Masters: Hello! Excuse me, how to calculate the angle of inclined top, inclined guide post and slider in plastic mold design, thank you! Better have a formula.

I don't know what mold you make, but I used to make notebook molds.

In the factory, the oblique pin is called the oblique pin, and the angle is calculated by trigonometric function according to your ejection stroke. The angle of ordinary oblique pin shall not exceed ten degrees. The length of the inclined guide post is calculated by trigonometric function according to the length of the demoulding part of your slider+safety distance.

The slider has no angle, only the slider wedge has inclination, which is generally 2 ~ 3 degrees larger than the inclined guide post.
