Ug how to calculate the number of icons on the inclined top of automobile grinding tools

Ug car abrasive inclined top drawing method is as follows:

1. When designing this type of inclined top, it should be noted that because our draft angle of inclined top is 12 degrees, the angle of inclined top is 2 degrees larger than the ejection angle. 2. At this time, the design should pay attention to the design benchmark, which is convenient for processing, positioning and marking. 3. Inclined top fixing method: straight ejector pin is adopted for fixing. 4. Fixing method of inclined ejector pin: MISUMI standard parts are adopted for fixing.

The inner buckle of automobile products is generally very long, so the stroke of the inclined top is very long and the ejection distance is very high. Both sides of the oblique plug must be angled (3-5 degrees) to prevent the oblique top from being burned to death by friction, and two datum planes must be made to facilitate processing.
