Abstract
PURPOSE: To carry out gate cutting and eject by means of a knockout rod, eliminate the necessity of a hydraulic unit for gate cutting and secure the purity of a product by switching between the state of connecting a gate cutting component with the knockout plate side and the cut-off state.
CONSTITUTION: A movable side die 10 is brought into close contact with a fixed side mold 12, and molten resin in a cavity 14 is filled from an injection device through a spray 20 and a gate section 22. An electromagnetic actuator 46 is worked to project a plunger 48. The plunger 48 is fixed in a through-hole 50 to move a connecting plate 38 integrally with a knockout plate 24. The knockout plate 26 is moved forward and the knockout plate 24, a driving rod 32, the connecting plate 38 and a gate-cut sleeve 52 are moved to the right to carry out cutting of a gate section 22 of a molded product 16. The knockout plate 24 returns to the initial stopping position to release the connection of the driving rod 32 with the connecting plate 38. After mold opening, the knockout rod 26 is moved to the right, and a sprue knockout pin 34 pushes a sprue section 36.
