How to improve the stability of mold has become a realistic problem faced by mold manufacturing enterprises.

The experience and skills of designers play a key role in the design and manufacture of molds. Whether the design is reasonable can only be confirmed by die test; The mold needs to be tried several times and revised repeatedly before it can be finally completed.

In production practice, once some molds are put into use on the production line, there will often be various problems, which can not meet the production requirements or technical requirements of the products, resulting in abnormal shutdown of the production line and many unstable factors.

Stability is divided into process stability and production stability. Process stability refers to the process scheme that meets the stability of qualified products; Production stability refers to the stable production capacity in the production process.

Because most domestic mold manufacturing enterprises are small and medium-sized enterprises, and quite a few of them are still in the traditional workshop-style production management stage, the stability of molds is often ignored, which leads to long mold development cycle and high manufacturing cost, which seriously restricts the development pace of enterprises.

Let's take a look at the main factors that affect the stability of die and stamping, namely: the use of die materials; Strength requirements of mold structural parts; Stability of stamping material performance; Fluctuation characteristics of material thickness; The range of material changes; Resistance of pull rod; Scope of BHF; Selection of lubricants, etc.

How to reasonably select mold materials has become one of the most important tasks in mold design. As we all know, there are many kinds of metal materials used in stamping dies. Because of the different functions of each part in the mold, the requirements and selection principles of materials are not the same. Therefore, in the selection of mold materials, in addition to high strength, high wear resistance and appropriate toughness, the characteristics and output requirements of processed product materials must be fully considered to meet the stability requirements of mold forming.

In order to solve the problem of mold stability, the following aspects must be strictly controlled:

1. In the process formulation stage, through the analysis of products, the possible defects of products in manufacturing are predicted, so as to formulate a stable manufacturing process plan;

2. Implement standardization of production process and production technology;

3. Establish a database and constantly summarize and optimize it;

4. With the help of CAE analysis software system, the optimal solution is obtained.
