Manufacturing process of cemented carbide mold formed parts. The manufacturing process of formed parts and the types of processing processes. The modern cemented carbide mold manufacturing process has been very simplified. Among them, the standard parts of the mold not only have the accuracy and quality to meet the assembly requirements, but also can be purchased from the market. The blanks of the formed parts, Including forgings and rolling templates, they can also be purchased from the market. Therefore, the main process contents in the cemented carbide mold manufacturing process are only the manufacturing process of formed parts and the mold assembly process.

The manufacturing process and sequence of the formed parts are:

1. Forming processing of formed parts, including hole system processing, groove and plane processing, etc.

2. Finishing processing of the formed part surface, including quenching, nitriding process and surface strengthening process, etc.

3. Finishing processing of formed parts, including plastic model cavity skin texture processing, polishing and grinding processing.

It can be seen that the forming of stamping molds and forming molds has become a key processing technology. The commonly used forming processing methods of formed parts include the following:

1. CNC forming milling technology is the main process method for processing molded parts such as plastic injection molds and die-casting molds. In particular, the application of high-speed milling technology and 4-5 axis linkage machining technology has become the main method of modern processing technology for formed parts. .

2. The EDM forming process is often used for general precision forming model cavity processing. It is often used for precision machining of formed parts after forming milling to reduce the surface roughness value and reduce the workload of grinding and polishing.

3. CNC, precision coordinate hole system processing technology

4. CNC and precision wire EDM processing technology are often used in the final processing of general die-formed parts, and are also used in the pre-processing of high-precision molded parts.

5. Precision forming and grinding processing technology, mainly used for precision forming processing of punch and concave die punch blocks

6. Extrusion molding process of mold cavity and precision casting molding process. The former is mainly used for simple shape and shallow cavity processing, while the latter is mainly used for the forming of large concave molds in automobile rolling dies, etc.
