Why Do You Need Inserts For Injection Mold Processing?
Aug 18, 2021
Mold inserts are widely used in injection mold processing, mainly used in front molds, rear molds, sliders and inclined tops. So why do injection mold processing require inserts, and what is the purpose of injection mold processing inserts? Let's take a look together.
1. Save injection mold manufacturing materials
As we all know, the injection mold uses a relatively regular block steel with a fixed shape to fix the material, but the material of the front and rear molds is determined by the height of z, whether it is the front mold or the rear mold, if one place is higher than other places , You can make inserts to reduce the height of the mold.
2. Convenient to change the mold
Where the injection mold is frequently modified, it can be disassembled to make inserts. When changing the mold in the future, only need to change the inserts, and even several more inserts can be replaced when the mold is opened, so that it is convenient to modify the mold.
3. Conducive to the exhaust of injection molds
The exhaust of the injection molding mold is very important. If the venting is not good, air traps will appear in the mold cavity, especially in relatively deep bones. During injection molding, the product is prone to defects such as bubbles or shrinkage, lack of glue, whitening or black spots. Therefore, inserts can be added where the mold needs to be vented, and the fitting gap of the inserts can be used for venting.
4. Convenient injection mold processing
There are some deep bones in the injection mold, and it is difficult for the tool to process. Although it can be processed by EDM, the EDM processing speed is slow and the processing efficiency is not high. Therefore, the insert is generally selected to reduce the processing difficulty and facilitate the exhaust. The other is the deep-bone type saving mold, because it is inconvenient to save the mold in the place where the mold must be saved, but it is much more convenient to open the insert in these places and disassemble the save.
5. Extend the service life of the injection mold
Generally speaking, the place where the insert is designed for the injection mold is often the easily damaged place in the mold. Once the insert is damaged, it can be replaced, thereby prolonging the service life of the injection mold and saving time and money.
