The portion where the undercut process is performed linked along with the movement of mold opening. The amount of movement of the slide core and the angle and the length of the angular pin are key factors to this unit.
The locking block installed to the cavity plate receives the pressure from the injection when closing the mold. Upon opening of the mold, the slide core moves backward by the force from the angular pin and the spring, thus releasing the part.
Some import tips might be ignored for slide gibs on mold design. But these tips are critical to ensure an injection mold with a long life.
1. Gib cavity depth “A” not less than 1/3H. 2. Gib height “B” not less than 2/3H, exceed the center of gravity because the slides usually lay horizontally when working. 3. Gib length “C” not less than 0.6H and 0.6L. 4. There are two rules related to Z:
-If Z wider than 6-1/2 inch, need to add one rail in the middle of the slide.
-If Z wider than 4-1/2 inch, need to design two cam pins.
All of these things we made just have one goal, to let the slide moves stably.
