a suitable dip angle for designing a tilted lifter mechanism is very important
a suitable dip angle for designing a tilted lifter mechanism is very important, I think the pin’s dip angle B should be taken 5—25 degree ， […]
I have a tip for designing the tilted lifter mechanism of a mold
I have a tip for designing a tilted lifter mechanism, to endow the mechanism with restoration function, the length of circular bead for restoration should be adopted preferably larger under possible conditions, […]
angle pin core-pulling mechanism
in first-rate mold solution co, ltd, our designer often design an angle pin core-pulling mechanism, […]
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.
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.
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.
Plastic part remains on the moving mold
When the slide is set on the fixed mold, […]
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 [...]
