use that kind of core-pulling mechanism in a mold
Use preferably core-pulling mechanism wherein the angle pin is located in the fixed mold and the slide in the moving mold.
use a suitable angle in the core-pulling mechanism of a mold
Wedge angle of the wedge block should be larger than the obliquity of angle pin, usually larger than 2—3 degrees; otherwise, the angle pin can not drive the slide.
dip angle of angle pin in the core-pulling mechanism of a mold
The size of dip angle is not only related with the bending force of angle pin and the actually realized pulling force but also connected with the working length of angle pin, […]
