摘要： A multi-level stacked mold having at least two and as many as four levels of cavities has a stock distribution mold block centred axially of the stacked mold blocks, the axially extending stock inlet passage to the distribution block connecting with radially off-set stock transfer passages that cross the axially openable mold block interfaces, into the adjoining mold blocks. These openable stock transfer passages, are each provided at their respective, non-encapsulated, radially off-set, opening interfaces with a valveless anti-drool arrangement. The mold flow passage system is subject to continual, extreme, thermal cycling and cyclical mechanical loading, during the repeated opening-and-closing cycles of the mold. Each separable anti-drool sealing interface has a relatively axially displaceable portion extending to bridge the initial gap opening between adjacent mold blocks and serving as an expansible piston means. This extension of the displaceable "expansible piston means" portion is pressure responsive and serves to increase the internal volume of the adjacent transfer passage, while permitting equalizing the pressure of stock in the passage to atmospheric pressure, thus reducing the likelihood of the drooling of liquid plastic into the opening interspace, or the induction of atmospheric air into the flow passages.

摘要： An injection mold typically defines multiple cavities. A mold gate is provided which comprises a rotary spherical member having a sprue conduit extending transversely therethrough. Highly accurate sequential molding of multiple cavities can be achieved in this manner, as well as other advantages. Also, this arrangement permits a linear, straight sprue conduit which is free of any sharp turns.

摘要： Injection molding machines for making plastic articles having a stack mold arrangement frequently suffer from the problem of unbalanced forces. Various novel techniques for counteracting and/or avoiding the production of these forces are disclosed. These techniques include the use of latches to lock an injection nozzle to a sprue bar, the use of shutters to lock the sprue bar to a stationary platen, the use of a force compensator in a moving stack mold half, and the use of an injection nozzle axially offset from the sprue bar.

摘要： A stack injection molding system for conveying melt from an upstream heated nozzle seated in a fixed mold platen to an aligned downstream heated nozzle in a movable mold platen. The upstream dowstream nozzles each have a nose portion with a forward face which abuts against each other in the parting line in the closed position. The melt passage extends through aligned central melt bores in the nozzles which taper inwardly adjacent the forward faces to form a sprue gate where they join. While both nozzles have an integral electrical heating element, only the heating element of the upstream nozzle has a circular forward portion which is brazed in the nose portion to encircle the melt bore and provide more heat and better control adjacent the sprue gate. Before the mold is opened along the parting line for ejection during the injection cycle, power to the heating elements of the nozzles is turned off to avoid drooling of melt from the open sprue gate.

摘要： This invention relates to injection molding and particularly to a melt transfer system for stack molding. According to the invention, a novel combination of known melt flow control valve units are arranged and operated to control the flow of pressurized melt from the stationary platen adjacent the molding machine to a manifold in the center moving platen. One control valve unit is located in the stationary platen in alignment with another control valve unit located in the moving platen. When the moving platen is in the closed position adjacent the stationary platen, the gates of the two control valve units abut and when the valve pins of the two control valve units are actuated to the open position, pressurized melt will flow through the gates from the stationary platen to the moving platen. The hot runner passage extends from the molding machine through the control valve unit located in the stationary platen. Through the gates into the control valve unit located in the moving platen, and then through the manifold system to the cavities located on opposing faces of the moving platen. In a second embodiment, a first cavity is located between the above two gates, and a third control valve unit is located in the moving platen in abutting alignment with the second control valve unit and its gate extends to a second cavity of the opposite face of the moving platen.

摘要： The present invention relates to a method for use in injection molding with the capability to have precise and adjustable control of the molten plastic flow when molding at least two (2) non-identical (i.e. with more than 50% difference in weight or form) or identical complex-shaped and intricate plastic parts at the same time, utilising a mold with at least two (2) parting layers via a standard conventional injection machine. This invention incorporates the principle of having two (2) valve pins in which their movements are back-to-back and can be independently opened and closed as controlled by stepper, servo or linear motors linked to a separate independent tool controller. The two (2) valve pins are positioned at the floating half of the mold for sequential, stack or multi-layer mold with multiple cavities.
