One kind of oscillating rail arcuate pulling mechanism

The present invention relates to a rail swing arc core pulling means, disposed on a molding machine with a mold core back portion is placed in the fixed mold injection molding machine, comprising a guide plate, a guide groove, a guide pin, L-type swing bar, the locking mechanism, the arcuate guide and a slider block, L-type lever and a first rocking lever comprises a second lever; a first lever and the second lever is connected rotationally fixed on the movable mold part of the injection molding machine; a guide plate the fixed mold is fixed to the injection molding machine, the guide plate defines a guide groove, guide grooves and a certain angle from vertical, axially movable guide pins in the guide grooves and the guide pin and the other end of the first lever rotation, and the other end fixedly connected to the slider, the slider is fixedly connected to the core back portion of the mold, the movable mold section is provided with a locking mechanism of the second rod, such that the guide pin rises to the top of the locking mechanism when the locking slide guide groove Piece. The mechanism may utilize mold force to realize the movement of the injection molding machine, to reduce costs and save energy.
