INJECTION MOLDING DIE AND AN INJECTION MOLDING METHOD USING A BMC(BULK MOLDING COMPOUND), CAPABLE OF PREVENTING UNFINISHED MOLDING BY FORMING AN OVERFLOW RECEIVING UNIT AT REGULAR INTERVAL AT UPPER AND LOWER CAVITIES

摘要

PURPOSE: An injection molding die and an injection molding method using a BMC(Bulk Molding Compound) is provided to eject easily a finished product and a sprue from a manifold by preventing the temperature of a mold from be dissipated to the outside or a sprue unit using a heat insulating panel unit and a cooling block.;CONSTITUTION: An injection molding die(1000) comprises a sprue bush and a manifold(1300). The sprue bush is installed in the upper center. The manifold guides BMC material ejected through the sprue bush to a runner unit, and a gate unit or a sprue unit. The manifold supplies BMC material to upper and lower cavities(1121,1211). The manifold maintains keeps BMC material supplied to a cavity at the temperature of 50~60°C in not solid or melted state but fluid state.;COPYRIGHT KIPO 2010
