What is the difference between mold core and cavity?

1. Definition of core and cavity

Molds are commonly used processing tools in industrial production and are used to manufacture various industrial products. The mold consists of two parts, the upper part is the upper template and the lower part is the lower template. When the upper and lower templates are closed, a mold space is formed in the middle, corresponding to the appearance and internal structure of the product respectively. The space in the mold is divided into two parts, namely the core and the cavity.

The core generally refers to the convex part of the space in the mold, such as holes and bumps in parts. The cavity refers to the convex part of the space in the mold, such as the shape and edge of the component.

2. The difference between core and cavity

The core and cavity in the mold have different functions, so they have different structural forms. The core and cavity have different positions in the mold. The core is in the lower template and the cavity is in the upper template. The core is the internal protrusion of the workpiece, while the cavity is the external shape of the workpiece. The core is a raised part that needs to be cut out from other workpieces; the cavity is a part of the mold used for shaping and positioning.

3. The importance of core and cavity

The core and cavity are both very important parts of the mold. They form the shape and size of the product parts in the mold. The size, parallelism and position of the gap between the core and the cavity will affect the size, quality and accuracy of the product. In order to ensure that the product meets the design requirements and specifications, the core and cavity must be accurately manufactured when manufacturing the mold, and the gaps and distances between them must be strictly controlled to ensure the correctness and consistency of the product.

4. Summary

In mold manufacturing, the core and cavity are very important parts of the mold. They have different functions and different positions, but their accuracy has a great impact on t
