Structure and composition of injection mold
Author:
Injection mold is a common mold used to manufacture plastic products. Its main structure is composed of mold base, mold core and mold cavity.
The mold base is the foundation of the entire injection mold, which is responsible for positioning the mold core and mold cavity, and supporting the entire mold. Mold holders are usually made of high-strength alloy steel or engineering plastics to ensure adequate stability and strength.
The mold core is the internal cavity part of the mold used to form the internal shape of the product. It is usually made of high-hardness tool steel for durability and resistance to wear and deformation during injection molding at high temperatures and pressures. The geometry and size of the mold core depends on the requirements of the final product.
The mold cavity is the external shape part of the mold used to form the external shape of the product. It is usually made of the same or similar material as the mold core. Like the mold core, the geometry and size of the mold cavity depends on the requirements of the final product.
In addition to the above three main components, the injection mold also includes some other necessary parts, such as positioning pins, guide posts, thimbles, etc. These components position, guide and control the injection molding process during the use of the mold.
In short, the structure of the injection mold is mainly composed of the mold base, the mold core and the mold cavity. They each bear different functions and are used together to achieve the production of plastic products. For the plastic products production industry, it is very important to understand the structure and composition of injection molds, which helps to improve production efficiency and product quality.
