摘要： An apparatus for injection molding of plastics material in accordance with a gas or liquid injection method. The apparatus includes a nozzle which can be applied to the injection molding die or the injection mold. This nozzle enables selectively the sole injection of plastics material melt, the simultaneous injection of plastics material melt and medium as well as the sole injection of medium into the mold cavity of the injection molding die or injection mold. The melt is supplied to the nozzle mouth by the extruder screw cylinder of the extruder around a nozzle torpedo, while the medium is introduced into the nozzle so as to be spaced from the nozzle mouth. The automatic operation of the apparatus in the course of all three types of operation is made possible by locating a check valve in the melt supply line of the nozzle between the upstream end of the nozzle torpedo and the junction piece of the extruder screw cylinder, which check valve can be automatically brought into its closed position in direction counter to the extruder screw cylinder.

摘要： It is proposed that a pressure control device and/or pressure regulating device (8) be used for a fluid medium, in particular air or gas, preferably nitrogen, which is to be supplied to an injection mold in addition to the molten plastic, this pressure control device and/or pressure regulating device (8) being provided as a stationary, but preferably as a mobile unit between a pressure generator/pressure accumulator (7) and an injection system associated with the injection mold (3), e.g., in a nozzle head or add-on building block. The device has a main line (21) which leads from the pressure generator/pressure accumulator (7) to the injection system (27) and which is switchable by means of valve control only in such a way that it either lets through or blocks the inflow of media, a first branch line (28) leading to a receiver side of a pressure sensor (29) whose other receiver side is sensitive to the pressure of the medium in the injection mold, and a second branch line (30) which can be switched so as to let through or block flow via a valve control influenced by the pressure sensor (29) and, in so doing, forms a media outflow from the injection mold, in particular a return of media to the pressure generator/pressure accumulator (7). Essential features of this device consist in that the main line (21) branches into at least two parallel flow paths (23a and 23b), that each flow path (23a and 23b) is outfitted with a media inflow control valve (24a and 24b) which may be operated to let through or block flow, as required, that the media inflow control valves (24a and 24b) have different flow cross sections (25a, 25b), and that these media inflow control valves (24a and 24b) can be controlled individually and/or jointly in a stepwise manner depending on the pressure difference determined by the pressure sensor (29).

摘要： A closing unit for injection mold machines is disclosed which generally includes two end plates, guide crosspieces connecting the end plates at a distance from one another, an intermediate plate which is parallel to the end plates and displaceable longitudinally relative to the guide crosspieces and moving cylinders which abut an end plate and act at the intermediate plate via their piston rods. The moving cylinders also displace the intermediate plate along the guide crosspiece in the closing and opening direction to vary its distance from the other end plate. The intermediate plate and the other end plate form a gripping plate for the two mold halves of a form tool which is brought into its closing position by the two gripping plates. Increased closing force may be applied to the form tool at a central die via a pressure cushion insertable between one end plate and the intermediate plate.

摘要： The invention relates to a non-return valve, which is situated at the end of a plasticizing and injection screw to control the flow of plastic melt from the region of the screw channels of the plasticizing and injection screw to the region of the space in front of the screw of a preplasticizing cylinder, where the plasticizing and injection screw is situated, the non-return valve having a basic body, which is rigidly connected to the plasticizing and injection screw, and an outside part, which can move translationally and preferably also rotationally relative to the basic body, so as to allow the flow of plastic melt in a first position and block the flow of plastic melt in a second position. To improve the locking behavior of the non-return valve and to simplify its structure, the outside part has at least two melt lines, which are not connected to one another, and the basic body has at least one melt line, such that the melt lines, of which there are at least two, of the outside body, together with the melt line of the basic body, in the first position jointly form a fluidic connection between the region of the screw channels and the region of the space before the screw, and such that the fluidic connection between the region of the screw channels and the region of the space before the screw is interrupted in the second position by a region of the basic body.

摘要： An arrangement for securing a die to a die holder for use as a molding die in an injection molding machine permits the die to be oriented on the die holder in a number of different angularly rotated positions. Clamping bolts secured to the die extend perpendicularly of a contacting plane between the die and die holder and project into corresponding holes in the die holder. Slides are provided in passageways in the die holder with the passageways extending parallel to the contacting plane. The slides are displaceable in the passageways into securing and clamping engagement with the clamping bolts. The slides are wedge-shaped and inter-engage corresponding wedge-shaped recesses in the outer surface of the clamping bolts. The slides can be displaced by actuating members. Hydraulic piston cylinder units can be used as the actuating members for holding the slides in the clamped position during operation. The recesses in the clamping bolts are formed by circumferentially extending secant-like cuts in the outer surface of the bolts with the cuts having a wedge-shape corresponding to the wedge-shaped slides.
