Some of these classification methods cannot fully reflect the structure and forming processing characteristics of various molds, as well as their use functions. To this end, a comprehensive classification method based on the process properties and use objects of forming processing using molds is adopted, and the molds are divided into ten categories, and can be divided into several subcategories or varieties according to the mold structure, materials, use functions and mold making methods.

What are the structural types of mold processing in Dalian

There are many classification methods for Dalian mold processing, and they were often used in the past:

Classified according to the mold structure form, such as single-process mold, compound punching die, etc.;

Classification by object of use, such as automobile cover mold, motor mold, etc.;

Classified according to the nature of processing materials, such as molds for metal products, molds for non-metal making, etc.;

Classified by mold manufacturing materials, such as cemented carbide molds, etc.; Classified according to process properties, such as deep drawing die, powder metallurgy die, forging die, etc.

The determination of the process scheme is an important link that should be carried out after the processability analysis of stamping parts. It includes:

1) According to the requirements of the shape characteristics, dimensional accuracy and surface quality of the workpiece, conduct process analysis, judge its main properties, and determine the nature of the basic process. That is, the basic processes of blanking, punching, bending, deep drawing, flanging and expansion. List the single and complete operations required for stamping, which can generally be determined directly from the product part drawing requirements.

2) According to the process calculation, determine the number of processes. For stretched pieces, the number of deep drawings should also be calculated. The bent parts and blanking parts should also be processed one or several times according to their shape, size and accuracy requirements.

3) According to the deformation characteristics of each processing, dimensional accuracy requirements and the convenience of operation, determine the sequence of processes. For example, punching first and then bending, or bending first and then punching.

4) According to various factors such as production batch, size, precision requirements, mold manufacturing level, equipment capacity, etc., the single process that has been preliminarily arranged in sequence is given to the possible process combination. Such as composite stamping process, continuous stamping process, etc. Generally, thick material, low precision, small batch, large size stamping parts should be produced in a single process, and simple molds should be selected; Thin material, small size, large number of punching parts should be produced continuously using progressive dies; For punching parts with high type accuracy, composite dies should be used for stamping.

After determining the nature, sequence and combination of processes, the process scheme of stamping is determined. That is, the structural type of the mold in each process is determined.
