The technical level of mold design and manufacturing is also a comprehensive standard to measure the technical capabilities of an enterprise. Mold manufacturing and design are directly related to the production efficiency, quality and production cost of stamping parts.

Stamping dies can be called cold stamping dies, also commonly known as cold stamping dies. Stamping dies process materials in the cold stamping process and are a special processing equipment. The materials can be metallic or non-metallic materials. Stamping is a kind of The pressure processing method is carried out at room temperature. The mold is installed on the press, and pressure is applied to the material to separate or plastically deform the material, and then obtain the required parts.

Material selection in stamping die design

The materials used in stamping dies mainly include carbon steel, cemented carbide, low melting point alloy, zinc-based alloy, aluminum bronze, alloy steel, cast iron, cast steel, synthetic resin, polyurethane rubber, plastic, birch laminate, etc., which can be metal materials , It can also be a non-metallic material.

The material used to make the mold is also very strict. It not only requires high hardness, high strength and high wear resistance, but also requires proper toughness, high hardenability, no deformation during heat treatment, and no cracking during quenching.

In order to ensure the service life of the mold, it is necessary to select the mold material reasonably, implement the heat treatment process correctly, and select the appropriate steel grade and heat treatment process to correspond to the different uses of the mold. In addition, attention should be paid to the working state, stress conditions, and processing materials of the mold. The performance, production batch and productivity of the product, and should pay attention to the above requirements and performance.

According to the role of the mold in the composition structure, the mold structure is mainly composed of process parts and structural parts. Process components directly participate in the process until the process is completed. And in direct contact with the blank, the process part mainly includes the positioning part, the working part, the unloading part and the pressing part. However, structural parts are completely different from process parts. They do not directly participate in the process and have no direct contact with the blank. They only ensure the completion of the process or improve the function of the mold. The structural parts mainly include fasteners, guides, standard parts, etc. However, it should be noted that not all stamping dies must contain these parts.

The level of mold design and manufacturing is also a measure of a country's manufacturing capabilities, so it plays a decisive role in product quality, efficiency and new product development capabilities to a large extent. Therefore, related industries and enterprises should improve mold design and manufacturing capabilities.
