Process

The mold is clamped, and the viscous fluid plastic melt after plasticization is injected, held, cooled and fixed. The nozzle of the injection machine moves backward, and the main flow condensate is released from the sprue bush due to the rebound action of the spring 28, and the mold is opened along the I-I parting surface under the action of the spring 6, when the limit screw 4 acts as a limit position, The flow channel puller 7 pulls off the dot gate, and pulls the aggregate out of the cavity plate 25 to automatically fall. The cavity plate 25 continues to move backward under the moving template of the injection machine, and the limit screw 26 is limited. When the action is fixed, the fixed part stops moving; due to the shrinkage effect of the melt cooling, the plastic part is wrapped on the core, and the movable part continues to move backwards under the driving of the moving template of the injection machine, and the plastic part is released from the cavity, at the same time The inclined guide post 18 is opened by the Hough block 22 to complete the side core pulling action, and the movable mold part continues to move backward. When the limiting plate 20 acts as a limit, the pusher plate 9 causes the plastic part to be disengaged from the core. The mold clamping, the demolding mechanism, and the side core pulling mechanism are reset, and an injection cycle is completed.
