How to distinguish the punch and concave mold of the mold?

1. Definition and classification of punch and die

The male and female molds are the core components of molds (molds are tools used to make formed products). The punch is a mold with a convex shape. Its function is to force the material to flow to the convex parts of the mold during the forming process to achieve the purpose of forming. The concave mold is a mold with a concave shape. The material flows to the concave part to obtain the corresponding concave-shaped product.

From the perspective of the production process, the punch mold is generally used for the upper mold of formed parts or for one-time molding with a simple structure. Generally, the manufacturing difficulty is low and the manufacturing process is simple; while the female mold is used for the lower mold of formed parts or the work progress is more complicated. The multiple moldings are relatively difficult to produce and the process is complex.

2. Distinguishing the shape of punch and concave mold

The most obvious difference between the punch and the die is their shape. The shape of the punch mold is convex, which is the same as the shape of the product. It is often used to manufacture parts with raised patterns. The surface can also be set to be smooth or textured to produce different effects; while the concave mold The shape is concave, as opposed to the shape of the product, and is often used to make parts with concave patterns. The shape and size of the male and female molds must correspond to the molded parts, especially where there are beveled sides, the requirements are stricter to ensure the accuracy and quality of the molded products.

3. The difference between the manufacturing process of punch mold and concave mold

There are also certain differences in the manufacturing processes of punch and concave molds. The manufacturing process of the punch mold is relatively simple and can generally be made by stamping, casting, machining, etc. The manufacturing process of the concave mold is more complex and generally requires high-precision process technology such as electric discharge machining. During the production process, special attention needs to be paid to the shape formulation, material selection, CNC processing, smoothness, etc. to ensure the accuracy and quality of the molded products.

4. Combination application of punch and concave mold

In actual processing, punch and concave molds often need to be used in combination, so that more complex products can be manufactured. For example, when manufacturing a product with a convex-concave structure, two parts, the male mold and the female mold, need to be made first and then combined.

5. Summary

In practical applications, male and female molds are often used together to manufacture products with complex structures. For example, in the injection molding process, the combination of male and female molds can be used to manufacture plastic parts of various shapes. The design of male molds is mostly used in scenarios that require cutting, pressing, stamping or drilling holes on the surface of raw materials, while female molds It is often used to manufacture products that require protruding surfaces or where the surface shape needs to be pressed into raw materials.

Punch and die molds play an important role in modern manufacturing. The correct application of punch and die can greatly improve product manufacturing efficiency and improve production efficiency.
