INJECTION MOLDING APPARATUS

摘要

PURPOSE: An injection molding device is provided to omit a coating process by absorbing gas of a pre-set part which is pre-set in a mold cavity. CONSTITUTION: An injection molding device comprises a first sensor(100), a suction hole(200), a gas suction regulating unit(300), and a valve(400). The first sensor detects that melted resin is injected in a mold cavity(C). The fused resin is inserted to the cavity of the mold. The suck hole inhales gas from a specific part of the mold cavity. The gas suction regulating unit forms a part among one side of the cavity of the mold. If the fused resin is inserted to the cavity of the mold, a valve opens the suction hole. After the fused resin is accepted to the cavity of the mold, a pre-set time passes and the valve closes the suction hole.
