Abstract: A heated injection molding nozzle having a rear member and a forward member which is removable. A channel extends through the rear and forward members to convey pressurized melt to one or more gates extending through the mold to a cavity. The rear member has an electrical heating element with a spiral portion which extends around the melt channel. The forward member has a tapered rear portion which extends rearwardly into a matching tapered well in the rear member. The taper is sufficient so the tapered portion is frictionally retained in the well to removably mount the forward member to the rear member. This allows the forward member to be easily turned or driven out of engagement in the well to replace it with a new forward member or a forward member having a different configuration to provide a different type or arrangement of gating.

Abstract: A nozzle for injecting molten plastic includes a housing having an inlet and an outlet. Wires embedded in the housing serve to heat the housing. The housing defines a chamber, and a strainer is disposed in the chamber between first and second guides which are respectively located adjacent to the inlet and the outlet. The strainer and the guides divide the chamber into an outer compartment which surrounds the strainer and an inner compartment within the strainer. A rod extends through the inner compartment and carries first and second pistons which are slidably supported by the first and second guides, respectively, so that the rod can be moved between two terminal positions. Each of the pistons is provided with an axial blind bore and several radial bores which radiate from the associated blind bore. In a first terminal position of the rod, molten plastic from the inlet flows successively through the bores in the first piston, the inner compartment the strainer, the outer compartment and the outlet leaving contaminants in the inner compartment. In the second terminal position of the rod, molten plastic from the inlet flows successively through the bores in the first piston, the passages in the first guide, the outer compartment the strainer, the inner compartment, the bores in the second piston and a tube in register with the axial bore in such piston to flush the contaminants from the inner compartment.

Abstract: In an injection molding machine combined with a peripheral apparatus, control units capable of interchanging signals are provided for the molding machine and the peripheral apparatus. Each control unit comprises a memory device storing set molding data applied with numbers or identifications. When the control unit of the molding machine sends the set data number or identification to the control unit of the peripheral apparatus to read out from the memory devices, the set molding data are formed when the numbers or identifications coincide with each other.

Abstract: There is provided an apparatus for the manufacture of plastic parts from thermoplastic, thermoset and/or elastomer material by injection molding or reaction injection molding. The apparatus includes a multi-station locking unit of horizontal or vertical configuration adapted to hold a number of molds, and an associated injection unit for the simultaneous injection of the molds. The apparatus further has a movable center mold clamping plate sectioned lengthwise relative to the locking direction, the two parts of the plate being kept together by a high-speed clamping device and having arranged between the parts a melt conduction system having one or a number of separate melt conduction rails. Each melt conduction rail is rigidly clamped at its face between the sectioned mold clamping plate lengthwise relative to the direction of flow of the melt. The apparatus further includes a median centering collar and a widened melt inlet with rounded side walls adapted to receive the nozzle system and which are arranged on a flange of the melt conduction rail. The nozzle system includes a movable cut-off nozzle system part capable of being displaced within itself in the direction of injection and a stationary part which is rigidly mounted on the face side of the melt conduction rail. A melt compensation system is associated with the cut-off nozzle system and located within the melt conduction rail.
