Stream valve system closes injection hole, and knock-pin is parallel with mold core bottom end, and first motor shuts down, and water pump stops operation, back-shaped
Coolant liquid stops circulation in water cooling tube, and device restPoses
Wherein, the configuration of the present invention is simple, it is easy to operate, by way of machine driving group, to realize that automated production is promoted
What is operated is safety-type, by the up and down motion of the first fixed plate, completes the automatic open-close mold process of mold；It is being returned by coolant liquid
Shape water cooling tube shuttling movement, remains at mold work temperature within the scope of optimum working temperature；Pass through the second fixed plate
Movement, completes the automatic demoulding work of mold, and the design of fluid stopping valve system makes device stop charging when dividing mould, to save
Raw material.
