The Wonders and Innovations of Injection Molds

Injection molds, as an important cornerstone of modern manufacturing, the development and innovation of their technologies are of crucial importance.

The design process of injection molds is extremely complex and precise. From the initial analysis of the product, including the shape, size, accuracy requirements, etc., to determining the parting surface, the number and arrangement of cavities, every link requires rigorous consideration. For example, when designing the injection mold for a mobile phone case, the position selection of the parting surface should fully consider the structural characteristics of the case to ensure that the mold can smoothly eject the product from the cavity when the mold is opened without affecting the appearance of the product.

The determination of the number of cavities needs to comprehensively consider factors such as the production batch of the product, the specifications of the injection molding machine, and the cost of the mold. If the production batch is large, in order to improve production efficiency, a multi-cavity mold structure may be selected, but this will also increase the manufacturing difficulty and cost of the mold.

The selection of the injection molding machine is also a key link. Different injection molding machines have different parameters such as injection pressure, clamping force, and injection volume. It is necessary to select the appropriate injection molding machine model according to the specific requirements of the mold and the product.

The design of the gating system is related to whether the plastic melt can fill the cavity smoothly and affects the quality of the product. The main runner, the runner, the gate, and the cold slug well all need to be carefully designed. For example, the selection of the location and form of the gate directly affects the appearance and internal quality of the product. For some products with high appearance requirements, a submarine gate may be used to avoid leaving obvious gate marks on the product surface.

The design of the demolding mechanism must ensure that the product can be smoothly ejected from the mold after molding without causing damage to the product. Common demolding mechanisms include ejector pin demolding and ejector plate demolding. The design of its structure and quantity needs to be determined according to the shape and size of the product.

The cooling system plays an important role in controlling the molding cycle and quality of the product. By reasonably arranging the cooling water channels, the mold temperature can be effectively reduced, so that the plastic melt can be quickly cooled and solidified in the cavity, improving production efficiency and product quality.

In short, the design and manufacturing of injection molds is a comprehensive project that requires knowledge and technologies in multiple fields. Continuous innovation and optimization are the keys to promoting the development of the injection mold industry.

In this article, we will delve into the nuances of rubber compression molding, exploring its process, advantages, applications, and how it compares to other molding techniques, including the use of composite molds.

Understanding the Rubber Compression Molding Process

Rubber compression molding involves shaping rubber material by placing it into a heated mold cavity, where it is compressed into the desired form. The process typically follows these steps:

Preparation of the Rubber Material: The rubber material, often in the form of pre-measured blanks or preforms, is prepared. These preforms are made from raw rubber, mixed with additives to enhance their properties, such as curing agents, fillers, and stabilizers.

Mold Setup: The mold, usually made from metal, is preheated to a specific temperature. The preheating ensures that the rubber cures uniformly when compressed.

Loading the Preform: The rubber preform is placed into the mold cavity. The mold is then closed, and hydraulic or mechanical pressure is applied to force the rubber into the shape of the cavity.

Curing: As the mold is compressed, the heat causes the rubber to cure. Curing, or vulcanization, is a chemical process that enhances the elasticity and strength of the rubber. The curing time depends on the type of rubber and the complexity of the mold design.

Demolding: Once the rubber has cured, the mold is opened, and the part is removed. The part may require further processing, such as trimming excess material or post-curing, to achieve the desired properties.

Advantages of Rubber Compression Molding

Rubber compression molding offers several distinct advantages, making it the preferred method for specific applications:

Cost-Effective for Low-Volume Production: Compared to other molding processes like injection molding or the use of composite molds, compression molding is more cost-effective for low-volume production runs. The tooling costs are lower, and it’s suitable for prototyping and custom orders.

Complex Geometries: This process is well-suited for producing parts with intricate geometries and varying thicknesses. The ability to apply pressure uniformly across the mold allows for the creation of detailed and precise components.

Material Versatility: Rubber compression molding can accommodate a wide range of rubber materials, including natural rubber, silicone, EPDM, neoprene, and more. This versatility allows manufacturers to choose the best material based on the application’s specific requirements.

High-Strength Parts: The curing process in compression molding results in parts with high tensile strength and excellent durability. These properties are essential for applications that demand resilient components.

What Are the Classification of Injection Mold Processing?

What Are the Classification of Injection Mold Processing?

Ⅰ. The plastic injection mold processing

Injection molding is a relatively common manufacturing method of industrial products in machining processing. This processing technology obtains the required shape by processing rubber and plastic. There are many types of injection mold processing. In the process of processing, the processing technology should be selected according to the requirements of the injection product.

 Ⅱ. The classification of plastic injection mold processing

1. Single parting surface injection mold

 When the mold is opened, the movable mold and the fixed mold are separated, so that the plastic part is taken out, which is called a single parting surface mold. This processing method is the simplest of the plastic injection mold and molding. It can be divided into single-cavity injection molds or multi-cavity injection molds according to the design. It is widely used in today's production.

 2. Double parting surface injection mold

 Double parting surface injection molding has two parting surfaces. Compared with single parting surface injection molds, double parting surface injection molds have a movable intermediate plate in the fixed mold part, so this type of injection mold is called three-plate injection mold. It is most commonly used for single-cavity or multi-cavity molds with point gate feeding.

 3. Injection mold with lateral parting and core pulling mechanism

 When the plastic part has a side hole or a side depression, it needs to be formed with a core or slider that can move laterally. After injection molding, the movable mold will move down for a certain distance, and then the inclined surface of the bending pin fixed on the fixed template forces the slider to move outwards. At this time, the push rod of the ejection mechanism pushes the plastic part to take off from the core.

 4. Injection mold with movable forming parts

 Due to some special structures of plastic parts, injection molding will be required to be set into movable injection molded parts, such as movable punches, dies, movable inserts, movable threaded cores or shaped rings. During demolding, it can be moved out of the mold together with the plastic part and separated from the plastic part.

 5. Automatic thread unloading injection mold

 For plastic parts with threads, when automatic demolding is required, a freely rotatable thread core or ring can be set on the mold, and the mold opening action or the rotation mechanism of the injection molding machine can be used to drive the thread core or the threaded ring rotates and the plastic part comes out.

 6. Runnerless injection mold

 Runnerless injection mold refers to the method of adiabatic heating of the runner to keep the plastic between the nozzle and the cavity of the injection molding machine in a molten state, so that there is no condensate in the pouring system when the mold is opened and the plastic part is taken out.

 7. The injection mold of the demoulding mechanism on the fixed mold

 In the injection mold, the demolding device is installed on the side of the movable mold, which is of great help to the ejector device in the opening and closing system of the injection molding machine. In actual production, because of the shape limitation of some plastic parts, leaving the plastic parts on the side of the fixed mold is more helpful for forming.

Basic Requirements for Structural Design of Plastic Toy Molds

Introduction

The world of plastic toys is filled with creativity and imagination, bringing joy to children and collectors alike. Behind every successful plastic toy lies a well-designed mold that ensures its shape, functionality, and durability.The structural design of plastic toy molds plays a crucial role in manufacturing high-quality toys. In this article, we'll look at the fundamental conditions for producing high-quality plastic toy moulds.

Material Choice

Making the proper material choice is crucial when creating plastic toy moulds. The substance should have qualities like strong heat resistance, high strength, and dimensional stability.Commonly used materials for toy molds include hardened steel, aluminum alloys, and pre-hardened steel. Each material has its own benefits and drawbacks, so it's important to take into account things like production volume, price, and the complexity of the toy design.

Mould Cavity Concept

The final shape and characteristics of the plastic toy are determined by the mould cavity. It is crucial to build a cavity that faithfully reproduces the desired toy design. Factors such as draft angles, parting lines, and ejection mechanisms should be carefully considered to ensure smooth ejection and minimize defects like warping or flash. The mold cavity should also allow for easy assembly and disassembly for maintenance and repair purposes.

System for Cooling

In the moulding of plastic toys, effective cooling is essential for achieving shorter cycle times and lower production costs. The mold's cooling system aids in regulating the plastic's temperature and solidification, ensuring correct filling and avoiding deformations. Properly designed cooling channels, strategically placed near critical areas, can facilitate uniform cooling and minimize cycle time.

Venting

In order to allow air and gases to escape from the mould during the injection moulding process, venting is a crucial component of mould design. Insufficient venting can lead to issues such as incomplete filling, burn marks, or even damage to the mold. Adequate venting ensures high-quality parts with minimal defects. Air entrapment can be avoided and smoother filling is encouraged by strategically placing vents, which are normally found at the end of the flow route.

Ejection System

The ejection system is responsible for removing the molded toy from the mold cavity.  Designing an ejection system that delivers consistent and regulated ejection is essential in order to avoid damaging the toy or the mould. Common ejection mechanisms include ejector pins, ejector sleeves, and stripper plates.  To ensure safe and effective demolding, the design should take into account elements including part shape, undercuts, and the needed ejection force.

Mold Surface Finish

The surface finish of the mold directly affects the appearance of the final toy.   A smooth and polished mold surface minimizes the risk of imperfections and enhances the toy's overall quality. To give the mould the appropriate surface quality and texture, surface coatings or treatments, such as chrome plating or texturing, might be used.  The selection of suitable surface finishes that complement the toy's design and manufacturing specifications should be given careful thought.

Conclusion

Designing plastic toy molds requires careful attention to detail and consideration of various factors to ensure the production of high-quality toys.  Each component is crucial to the overall structural design, including material choice, mould cavity design, cooling systems, venting, ejection systems, and mould surface treatments. By adhering to these basic requirements, manufacturers can create molds that produce visually appealing, functionally sound, and durable plastic toys that bring joy and entertainment to children around the world.
