Many people may not understand the processing process of injection molds , so they will have no idea about the specific processing content and cost, which requires some understanding of the design process of injection molds.
1. Technical requirements for plastic products
The design requirements of injection molds are to understand the technical requirements of plastic products in advance, such as the use, usage status and related work requirements of plastic products. Process depth analysis should be carried out based on the dimensional accuracy, surface roughness, product shape and shape tolerance proposed in the figure. In addition, the geometric shape of the plastic products, process rounded corners, uniformity of wall thickness and mold release slope should be specifically analyzed to facilitate the production of plastic products to meet the molding process requirements.
2. Production technical requirements
During the injection mold processing process, the number of cavity holes and the model of the injection molding machine need to be determined based on the shape and size of the plastic product, the projection area of the injection, the estimated product volume, and the weight.
3. Main structural design of injection mold
In this process, the structure of the injection mold is mainly considered, the rationality of the mold processing and manufacturing process is required, and the special mechanisms required for the mold structure are also required.
4. Draw a sketch
Through the above detailed information, a complete structural diagram of the mold is drawn and effective.
V. Calculation
According to the relevant requirements for the dimensional accuracy of plastic products, the molding size of molded parts is calculated and the shrinkage rate of plastic molding can be accurately controlled, so as to improve the dimensional accuracy of plastic products.
6. Draw mold design and assembly work drawings
The mold assembly drawings of injection molded products mainly include mold sizes and certain technical conditions.
7. Parts and mold working drawings
In addition to drawing the entire injection molding module, it is also necessary to draw the working drawing of the parts, marking the dimensions, surface roughness, shape and position tolerances and accuracy, etc.
8. Review
Professionals review and proofread the drawings, and then they can be unloaded and put into mold processing.
9. Technology improvement and drawing and data setting
After the injection mold is qualified after relevant tests, mass production can be started.
