Talking about the main points of mold design, do you know?

Mold design is a very important process before production. It requires certain professional knowledge to make good use of molds. So what are the important points of mold design.

1. Generally, flat finished products should not be fed in between to prevent bending and deformation.

2. When there is a thimble under the slider or the oblique tip is broken, the upper and lower ejection plates must be equipped with a forced return mechanism.

3. The draft angle of the finished product is based on the reduction of material.

4. When designing the waterway, try not to use water pipes directly connected to the mold core, but use the mold inlet pipe to repair the "O" RING to connect the mold core.

5. Three principles of cooling water: A. Fast cooling, B. Uniform mold temperature, C. Convenient processing.

6. The oblique tip distance from the mold center should be rounded.

7. The method of handling the inner barb is generally to use the oblique tip, the inner slider, and the peeling plate (ejecting the middle plate). The ejector tip should be avoided under the slider to avoid collision or interference.

8. Generally, the mold core exceeds the contour of the finished product by 20-30mm, and the distance from the center of the mold should be rounded. The template is 20-30mm away from the frame of the mold core. If there is a slider, consider increasing the template, and pay special attention to avoiding interference with the return pin.

The above are the basic and important points of mold design, which must be understood. Of course, there are many important points besides the above. You have to use your own experience to summarize and analyze, I hope it will be helpful to everyone. Ruibole is a ten-year mold technology manufacturer who can provide you with drawings for free.
