摘要： An injection molding apparatus includes an injection piston that is slidable within a nozzle having a movable valve gate pin. The injection piston is movable from a retracted position to an extended position in order to force melt towards a mold cavity. A valve is located at a forward end of the piston to selectively block communication between a recess, which is provided in an outer wall of the piston adjacent the valve, and a melt chamber of the nozzle. Movement of the injection piston from the retracted position to the extended position causes the valve to close so that the predetermined volume of melt located below the valve is forced into the mold cavity, when the valve gate pin opens the mold gate.

摘要： To obtain simultaneous filling of all cavities (K1-K4) in multicavity injection moulds, the mould cavity pressure (p) patterns in all cavities (K1-K4) are detected and the times (t1-t4) measured from the beginning of filling till a suitably chosen reference pressure (pR) is reached for each cavity (K1-K4). By interventions in the individual heating systems of the individual hot runners (5), the temperatures in these are altered to bring the measured times of the individual cavities more in line.

摘要： A tooling assembly (10) having complementary die sections. Die section (12) includes a face portion (14) having a tooling insert (16) mounted therein. Insert (16) includes an impression configuration (20) formed therein. Flow device assemblies (40) are in communication with impression configuration (20). Flow device assemblies (40) are variably rotatably mounted in die section (12) and are operatively connected to respective flow device actuation assemblies (60). Activation of flow device assemblies (60) can be performed manually, or automatically by, for example, respective conventional motors (90). Motors (90) may be electrical motors each with a driving mechanism attached to a respective flow control device (60). Activation of a flow device actuation assembly (60) causes a respective flow device assembly (40) to rotate and to thereby change its posture of communication with respect to impression configuration (20).

摘要： An adaptive controller is provided for controlling the transition, in an injection molding apparatus, from the injection stage to the packing stage. The controller operates by controlling the velocity of the ram during the injection stage, and controlling the ram pressure during the packing stage. The controller anticipates the transition from the injection stage to the packing stage by monitoring the ratio of pressure to velocity. The divergence of this ratio forecasts the onset of the packing stage. At this time, a pressure relief valve is preset in anticipation of the packing stage, to prevent a pressure spike during the transition period. The flow control valve is held constant during the transition.

摘要： A method for manufacturing a glass plate equipped with a vehicle window-type resin frame includes performing injection molding of the resin frame by using two shaping molds having a cavity configured for the resin frame, disposing the glass plate inside the shaping molds such that the glass plate is retained by a retaining part that is adjacent to the cavity of the shaping molds, and injecting a resin into the cavity, wherein there is at least a partial gap between the glass plate and the retaining part, in a state in which the shaping molds are clamped together.
