The precision requirements of injection molding mold sliding components

The precision requirements of injection molding mold sliding components mainly include the following aspects:

The precision requirements of injection molding mold sliding components

1. Size accuracy: The size and accuracy of injection molding modules is high, especially mobile components involving molds, such as guide columns, guidelines, etc., the size accuracy requirements are within 0.005mm.


2. Parallelism: Injection molding modules need to maintain parallelity when working, that is, the parallelism between the axes of each slider is high, and generally requires within 0.02mm.


3. Surface cleanliness: The surface smoothness requirements of injection molding mold sliding components are high, especially in the part of the contact with plastic liquid, such as the mold cavity and the mouth, etc.

And the surface roughness requirement is within 0.8 μm.


4. Lubrication performance: Injection mold sliding components need to have good lubrication performance to reduce friction and wear, while ensuring the normal operation of the mold. You can use lubricating fat or lubricating oil to achieve the lubrication of sliding components.


5. Abrasion resistance: injection molding mold sliding components need to have high wear resistance to ensure its service life. It can be used to improve the wear resistance of sliding components by high -hardness materials or surface hardening.


In short, the precision requirements of injection molding mold sliding components are strict, mainly including size accuracy, parallel, surface smoothness, lubrication performance and
