Abstract
PURPOSE: To omit finishing process, carry out reliable mold gassing by providing the gate means by which a gate is shutted when injection is finished and the vent blocking means by which an air vent is shutted when injection is nearly finished.
CONSTITUTION: Between an upper mold 6 and a lower one 7 is provided a cavity 1 and on the lower mold 7, beneath a connecting hole 8 of an air vent 4 to a cavity 1, viz. beneath a gate 2 are respectively arranged a vent blocking means 5, a gate blocking means 3 so that they may freely protrude upward. Pins, sliding doors, moving blocks may be served as their blocking means. When molding materials 11 are injected the pins are fully open and when the gas in the cavity 1 is pushed out the air vent is shutted, then when injection is completly finished the gate beomes shutted. The diameters of the gate, vent can be expanded, increased injection speed is capable of quick filling of injecting material, therefore molding cycle is made shorter.
