What are the basic knowledge of injection molding (plastic) mold structure?

Injection molding (plastic) mold structure basic knowledge introduction. Injection molding (plastic) mold is a mold used to manufacture plastic products, and its manufacturing process needs to go through a number of steps, including plastic mold design, plastic mold processing, plastic mold assembly and debugging.

The following is a detailed explanation of the basic knowledge of injection molding (plastic) mold structure:

1. What are the basic structural components of injection molds

The basic structure of injection mold is mainly composed of mold bottom plate, mold core, mold cavity, guide post, guide sleeve, thimble, ejector rod, roof, positioning ring, cooling water channel and other parts. Among them, the mold bottom plate is the basic part of the mold, the mold core and the mold cavity are the core part for forming plastic products, the guide column and guide sleeve are used to locate the mold core and the mold cavity, the thimble and the ejector rod are used to ejector the forming part, the roof is used to fix the thimble and the ejector rod, the positioning ring is used to locate the mold core and the mold cavity, and the cooling water channel is used to cool the mold core and the mold cavity.

2. What are the manufacturing processes of injection molds

The manufacturing process of injection mold includes the steps of design, processing, assembly and debugging.

(1) Injection mold design. It is necessary to design the mold according to the shape and size of the plastic products, and determine the structure and size of the mold and other parameters. Then, according to the design drawings for mold processing, including CNC machining, EDM, wire cutting and other processes.

(2), injection mold processing and assembly. Assemble the processed mold parts, including mold core, mold cavity, guide post, guide sleeve, thimble, ejector rod, top plate, positioning ring, etc.

(3) Injection mold debugging. Carry out mold debugging, including adjusting the position of the mold core and mold cavity, adjusting the position of the thimble and the ejector rod, adjusting the flow of the cooling channel, etc.

3, what is the application range of injection mold

Injection moulds are widely used in the production of plastic products, including home appliances, automobiles, electronics, medical equipment, daily necessities and other fields. The application range of injection mold is more and more extensive, and its manufacturing technology and process are also constantly developing and innovating.

In summary, injection mold is a mold used to manufacture plastic products, and its manufacturing process needs to go through multiple steps, including design, processing, assembly and debugging. Injection molds have a wide range of applications, and their manufacturing technologies and processes are constantly developing and innovating.
