摘要： PROBLEM TO BE SOLVED: To provide an injection molding apparatus comprising a mold block, a nozzle, a gating system and a slug heater. SOLUTION: The mold block 16 forms a mold cavity 32 with a mold cavity inlet. The gating system 18 comprises a valve pin 44 and an actuator 46. The valve pin is freely movable between an opening position where a melted body can flow into a mold cavity and a closed position where the valve pin closes a flow passage for the melted body so that the melted body does not flow into the mold cavity. The actuator moves the valve pin between the opening position and the closed position. When the valve pin exists at the closed position, a cooling system is provided on at least one of the mold block and the valve pin to selectively solidifying the melted body to form a slug just at the upstream of the valve pin. When the valve pin is separated from the slug, the slug closes the melted body flow passage to substantially stop leakage of the melted body through the slug. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： The present invention provides a hot runner injection molding apparatus comprising a melt conveying system (M), a mold cavity (16) and a manifold heater (106,50"'). The melt conveying system (M) having a melt distribution manifold (28) with melt passage (12) for transferring melt from a source of pressurised melt to the mold cavity (16) and an injection nozzle (10) with a melt bore (42) in fluid communication with the melt passage (12) and the mold cavity (16) adjacent to the nozzle (10). The manifold heater (106,50"') includes a film heating element (302) adapted to provide heat to the melt distribution manifold (28).

摘要： An injection molding apparatus comprises mold block; nozzle; gating system; and slug heater. The gating system includes valve pin and actuator, where valve pin is movable between open position where melt flow is permitted into mold cavity, and closed position where valve pin blocks melt flow passage to prevent melt flow into mold cavity. The actuator is operatively connected to valve pin. An injection molding apparatus comprises a mold block; nozzle (14); gating system (18); and slug heater. The mold block defines a mold cavity (32) having a mold cavity inlet (32a). The nozzle has a nozzle inlet fluidically connectable downstream from a melt source and upstream from the mold cavity inlet, and a melt flow passage extends from the nozzle inlet to the mold cavity inlet. The gating system includes a valve pin (44) and actuator (46), where the valve pin is movable between an open position where melt flow is permitted into the mold cavity, and a closed position where the valve pin blocks the melt flow passage to prevent melt flow into the mold cavity. The actuator is operatively connected to the valve pin to move the valve pin between the open and closed positions. The mold block and/or valve pin includes a cooling system for selectively solidifying melt to form a slug immediately upstream from the valve pin when the valve pin is in closed position, where, in use, the slug blocks the melt flow passage to prevent melt leakage past the slug when the valve pin is away from the slug. The slug heater is thermally connectable to the slug and is configured for selectively melting the slug to permit melt flow in the melt flow passage. An Independent claim is also included for a method for controlling melt flow in an injection molding apparatus, comprising providing at gate passage (33) of mold cavity, a valve pin that is movable between an open position where the valve pin is at least partially removed from the gate passage to permit melt flow through the gate passage, to a closed position where the valve pin cooperates with the gate passage to inhibit melt flow, where the valve pin is outside the nozzle melt channel in both the open and closed positions and is away from the mold cavity in both the open and closed positions; and moving the valve pin between the open and closed position to control the flow of melt into the mold cavity.

At least one of the mold block and the valve pin includes a cooling system for selectively solidifying melt to form a slug immediately upstream from the valve pin when the valve pin is in the closed position. In use the slug blocks the melt flow passage to substantially prevent melt leakage past the slug when the valve pin is positioned away from the slug.
