The Process Of Injection Molding Of Automobile Lamp Mold

The injection molding process is a very complex physical process. There are many factors that affect the quality of the finished plastic parts, including mold design.
Calculate manufacturing, raw material performance, injection molding machine performance and injection molding process parameters. In the actual injection molding production, facing the plastic parts
For most quality defect problems, the first method will be faster and more convenient, which is to adjust the injection molding process. If the problem cannot be solved
The question will only consider changing the material or mold structure. The traditional way to adjust injection molding process parameters is the technician
Relying on the injection experience of similar molded products, the technicians determine the range of process parameters, and then repeatedly debug within this range.
There are great limitations in terms of technical personnel experience level, product and material types, and this method is relatively cumbersome and passive.
low efficiency.
Driven by the rapid development of computer technology, injection molding CAE technology has also developed rapidly and matured.
Tool design and manufacturing and injection molding process play an increasingly important role. Use injection molding CAE technology to simulate injection molding
The process of filling, holding pressure, and cooling, and predict the defects that may appear after the molding of the plastic part. The technical staff can analyze
Simulate the simulation results, find the cause of the problem and its main influencing factors, and find out effective solutions. Injection molding
The use of CAE technology can prevent problems before they happen, guide the optimization of product design, mold design and injection molding test molds, and shorten products
The production cycle improves efficiency and reduces production costs. However, only relying on CAE analysis to optimize the injection molding process cannot
Provide system optimization plan, and intuitively obtain the optimal injection molding process parameter combination. Therefore, this article will test design and CAE technology
Through the statistical analysis of data, the influence mechanism of various process parameters on product quality is studied, and the injection molding
The mathematical model of chemical targets and process parameters, through data processing and optimization methods, obtains the optimal value of the target and the corresponding process parameters.
