What are the basic knowledge of injection molds?

Injection molds are a tool for making plastic products, which plays a vital role in the plastic processing industry.

Below is the basic knowledge of 7 common injection molding molds:

(1) mold classification:
The injection molding mold can be divided into single -cavity molds, multi -cavity molds, household appliance molds, car molds, medical device molds, etc. according to structure and use. Different types of molds are suitable for different product manufacturing.

(2) Mold material:
Common mold materials include steel and aluminum alloy. Steels are usually used to make large and high -precision molds, while aluminum alloy is suitable for small and low -cost mold manufacturing.

(3) mold structure:
The injection molding mold is composed of the mold cavity, the core, the top -out mechanism, the guide agency, and the cooling system. The mold cavity and the mold core are the part of the shape of the product. The top -out institution is used to top the finished product, and the guide agency is used to ensure that the mold positioning is accurate and the cooling system is used to control the temperature of the mold.

(4) Mold design:
Mold design is a key link for the manufacturing of injection molds. Reasonable mold design can improve production efficiency, reduce costs, and ensure product quality. The design of the mold needs to consider the shape, size, and material characteristics of the product.

(5) Mold manufacturing process:
The mold manufacturing process includes mold processing, heat treatment, assembly and other links. Moom processing usually includes craftsmanship such as turning, milling, and grinding. Thermal treatment can improve the hardness and abrasion resistance of the mold. The assembly is to assemble each component into a complete mold.

(6) mold maintenance:
During use, the mold needs to be regularly maintained and maintained to ensure its normal operation and extend the service life. Maintenance work includes cleaning molds, lubrication molds, checking mold wear, etc.

(7) Mold life:
The life of the mold refers to the time or number of times that the mold can use normally. Mold life is affected by various factors, such as material selection, design quality, and use conditions. Reasonable use and maintenance of molds can extend their life.

To sum up, injection molding mold is an indispensable tool in the production process of plastic products. Understand the basic knowledge of injection molds, including mold classification, materials, structure, design, manufacturing process, maintenance and life, which helps improve the understanding and application of injection molds, so as to better produce plastic products.
