Injection mould hydraulic or pneumatic core-pulling mechanism

- May 27, 2015 -

Active core relies on hydraulic system of pressure systems, and modern new type injection molding machine itself with this core-pulling devices, use more convenient. Hydraulic core-pulling mechanism with transmission, pullout strength, core advantages of long distance, but generally have no such device for injection molding machine, thus less. If core in the fixed half the side, in front of the mold cylinder moves the side core and mold, this structure without locking device and side holes must be through holes, so no back side core or cores to withstand side pressure is small, tight side core lock cylinder pressure can move.
