Abstract

The invention discloses an anticollision type side pumping slider mechanism of a plastic injection mould, and the mechanism is used for solving the locking-limit problem of a side pumping slider of the plastic injection mould. The anticollision type side pumping slider mechanism comprises an oil cylinder, a side pumping slider and a side pumping slider locking-limit unit, wherein the telescopic arm of the oil cylinder is fixedly assembled with the side pumping slider and the side pumping slider locking-limit unit is matched with the side pumping slider. The anticollision type side pumping slider mechanism is in cooperation with the mould disassembly and assembly processes of the plastic injection mould; and by utilizing the limit on the action of the side pumping slider of the side pumping slider locking-limit unit, the side pumping slider is prevented from colliding with a movable mould when the side pumping slider arrives ahead of time during mould assembly, so that the service life of the plastic injection mould is prolonged, the manufacturing cost of products is lowered and the normal production schedule is ensured.

Description

Slide block mechanism is taken out in a kind of injection mold Anti-collision side
Technical field
Slide block mechanism is taken out in the side that the present invention relates to a kind of injection mold, and slide block mechanism is taken out in especially a kind of injection mold side with position limiting structure, belongs to injection molding technology field.
Background technology
Automotive back door, door-plate class injection molding part are all provided with the side opening for installing lock core in latch position, for meeting vehicle modeling requirement, above-mentioned vehicle body outward appearance parts do not allow to there is the flaws such as injection moulding clamp, therefore, injection mold will design the smooth demoulding of side core-pulling mechanism guarantee product back-off position.Because existing side core-pulling mechanism does not generally have locking position limiting structure, frequent generation side is taken out slide block and to be put in place in advance when matched moulds phenomenon, makes side take out slide block and dynamic model bumps against, and causes mould to damage the consequence of even scrapping, not only have impact on the normal progress of production, and add the manufacturing cost of product.
