side core position in the core-pulling mechanism of a mold
The core should be set preferably in the moving or fixed mold vertical against the parting line so that the side core can be pulled out through mold opening or the pulling action.
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.
Prevent mutual interference in the core-pulling mechanism of a mold
Try not to make the projection of the ejector pin coincide with that of the active core on the parting line to prevent mutual interference of the slide and the ejector unit during restoration.
core-pulling distance in the core-pulling mechanism of a mold
Pull the active core out from the molding position to a place not interfering ejection of the plastic parts, and the distance moved by the active core or slide is called core-pulling distance. Generally, core-pulling distance equals to the depth of side hole plus a safety distance of 2—3mm. A core-pulling mechanism for pulling a 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, […]
