摘要： An improved melt distribution system and method is provided for a multi-level stack mold having three or more moving platens. The injection machine communicates with a bifurcated sprue bar for providing pressurized melt through the first moving platen to a central distribution manifold in the second moving platen. From the central distribution manifold, the flow of pressurized melt is distributed to the first and third platens for transfer to a plurality of mold cavities.

摘要： An injection molding apparatus that includes a nozzle having a nozzle channel, a mold cavity in communication with the nozzle channel of the nozzle for receiving a melt stream of moldable material from the nozzle channel through a mold gate; and a valve pin that is axially movable through the nozzle channel of the nozzle between a first retracted position in which the valve pin closes the mold gate to block melt flow between the nozzle channel and the mold cavity, an extended position in which an end portion of the valve pin extends through the mold gate and into the mold cavity, and a third retracted position in which the end portion of the nozzle pin is withdrawn from the mold cavity into the nozzle and spaced apart from the mold gate thereby opening the mold gate. The end portion of the valve pin defines a melt flow path on an outer surface thereof that extends through the mold gate when the valve pin is in the extended position for transmitting the melt stream from the nozzle channel to the mold cavity when the valve pin is in the extended position.

摘要： A guide for a manifold plug of an injection molding apparatus comprises a guide body projecting from an inner wall of the manifold plug diametrically opposing an inlet of a manifold plug channel formed in the manifold plug. The inlet is aligned with a manifold channel of a manifold. The outlet of the manifold plug channel is aligned with a nozzle channel of a nozzle. The inlet is at an angle to the outlet. A guide surface is provided on the guide body for abutting a downstream portion of a valve pin extending into the manifold plug channel. The guide also facilitates flow of a melt stream of moldable material through the manifold plug channel.

摘要： A drool control apparatus having a piston disposed in a melt passage of a mold. The piston is moveable between a bypass position, where pressurised melt is permitted to flow past the piston to at least one nozzle, and a compression position, where the melt downstream of the piston is decompressed to inhibit drool at the nozzle.

摘要： A nozzle is provided for an injection molding apparatus. The nozzle includes a nozzle body, a heater, a tip, a tip surrounding piece. The nozzle body defines a nozzle body melt passage, which has an inlet that is adapted to be downstream from and in communication with a melt source. The heater is connected to said body for heating melt in said nozzle body melt passage. The tip defines a tip melt passage that is downstream from and in communication with said nozzle body melt passage. The tip melt passage has an outlet that is upstream from a gate in a mold component. The tip includes a tip sealing surface. The tip surrounding piece includes a first tip surrounding piece sealing surface. The first tip surrounding piece sealing surface and said tip sealing surface are separated by a gap. The gap is sized to inhibit the flow of melt between said first tip surrounding piece sealing surface and said tip sealing surface.

摘要： A nozzle for an injection molding apparatus is provided. The nozzle includes a nozzle body, a heater and a first gap seal surface. The nozzle body defines a nozzle body melt passage, that is adapted to be downstream from and in fluid communication with a melt source, and upstream from and in fluid communication with a gate into a mold cavity in a mold component. The heater is thermally connected to the nozzle body for heating melt in the nozzle body melt passage. The first gap seal surface is positioned on a structure that is connected at least indirectly to the nozzle body. The first gap seal surface is adapted to be separated by a gap with respect to a second gap seal surface on the mold component. The gap is sized to inhibit the flow of melt between the first gap seal surface and the second gap seal surface.
