s2, starting injection molding, wherein after the mold is filled with the plastic, redundant thermoplastic enters the movable hole (14), the movable rod (141) in the movable hole (14) is extruded, and the rotating wheel (143) is driven to rotate by the upper inclined rod (142);
s3, the clamping plate (146) is pulled back into the female die (1) through the lower inclined rod (144), so that the clamping block (22) is not blocked any more, the piston rod (21) is reset under the action of the reset spring, and the male die (2) is separated from the female die (1);
s4, at the same time, the piston rod (21) is reset to drive the rack plate (71) to move, the gear (83) drives the turntable (81) to rotate, and the T-shaped rod (82) is driven to extrude the arc-shaped rod (91)
S5, the arc-shaped rod (91) rotates along the breakpoint of the base (9) under the thrust action of the T-shaped rod (82), the rotating plate (93) is driven to rotate by taking the top end of the lever (92) as the center through the supporting action of the lever (92) on the rotating plate (93), and the push plate (94) is driven to move rightwards;
s6, finally, the arc-shaped rod (91) pushes the movable plate (41) to slide rightwards through the support column (6), and then the injection-molded workpiece inside is pushed out through the push rod (42), so that the effect of quick demoulding is achieved.
