Principles of processing mold production

Plastic products have long been used in all walks of life. Injection molds are an indispensable tool in the production of plastic products. Plastic molds determine the structure and size of the product. Therefore, if you want to make plastic products, you must understand the production principles of plastic injection processing molds. ,Summarized as follows:

1. At the beginning of the design of each injection product, the mold opening direction and parting line must be determined first to ensure that the core-pulling slider mechanism is minimized and the effect of the parting line on the appearance is eliminated.

2. Understand the details of each mold design and the purpose of the parts.

3. Appropriate demoulding slope can avoid product top damage, such as top white, top deformation, and top break.

4. Summarize the experience of injection molding process mold manufacturing in the work.

5. When designing injection products, the contradiction between product appearance, performance and process must be considered comprehensively. Sometimes a part of the manufacturability can be sacrificed to get a good appearance or performance.

6. Learn more about the working process of the injection molding machine to deepen the relationship between the mold and the injection molding machine.

7. Design the buckle device to share multiple buckles at the same time, so that the overall device will not be inoperable due to the damage of individual buckles, thereby increasing its service life, and more filtering and rounding corners to increase strength.

8. Under the factory, understand the process of processed products, and recognize the characteristics and limitations of each process.

9. The product identification is generally set on the inner surface of the product on a relatively flat surface, and adopts a convex form. Choose the surface where the normal direction and the mold opening direction ruler may be consistent to set the logo to avoid strain.

10. Understand the results of mold trial and mold modification of the mold designed by yourself, and learn lessons.

11. Inserting inserts in injection molded products can increase local strength, hardness, dimensional accuracy and set small threaded holes (shafts) to meet various special needs. At the same time, it will increase product costs.

12. When designing, try to use the more successful mold structure before.

13. Setting a reasonable fillet can also improve the processing technology of the mold. For example, the cavity can be directly milled with an R cutter to avoid low-efficiency electrical processing.

14. Know more about the impact of mold water on products.

15. As far as possible, the pillar should not be used alone. It should be connected to the outer wall or used with reinforcement ribs as far as possible. The purpose is to strengthen the strength of the pillar and make the rubber flow more smoothly.

16. Research some special mold structures and learn about the latest mold technology.
