The function of injection mold springs
Injection mold sprigs are indispensable components in injection mold processing, mainly used for the following aspects:
1. Ejector plate reset. After injection molding is completed, the spring pulls the ejector plate back to its original position for the next injection.
2. Side core pulling. After injection molding is finished, the spring pushes the side core out to remove the plastic product.
3. Positioning. The spring can be used to position various components in the mold, such as sliders and ejector pins.
4. Buffering. The spring can be used to buffer the impact force during injection molding, reducing mold wear.
When selecting injection mold springs, the following factors should be considered:
1. Spring type. Select the appropriate spring type according to the application requirements.
2. Spring size. The size of the spring should match the structure of the mold.
3. Spring material. The spring material should have sufficient strength and corrosion resistance.
4. Spring preload. The spring preload should ensure that the ejector plate or side core can be pulled back to its original position after injection molding is completed.
5. Spring service life. The spring service life should meet the molds’ use requirements.
Injection mold springs are commonly used parts in injection molds and play an important role in the injection molding process. In the mold design process, the type, size, and material of the spring should be fully considered to ensure the normal operation of the mold.
