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.
the slide should be in the chute after moving completion
Upon completion of core-pulling, the slide left in the chute should not be less than 2/3 of total length of slide.
the number of molding cycles is between 500K and 1M, used for volume production.
