    摘要: The invention relates to a device for producing hollow bodies from thermoplastically deformable plastic films, wherein a forming tool (2) is arranged in relation to a deformation unit in such a manner that the separation movement to eject manufactured hollow bodies can be directed downwards. Unforced guidance of a swivel table (1) into a guide groove (6) enables the proper weight of the swivel table (1) to be used in conjunction with the forming tool (2) to carry out the downward and swivel movement, thereby substantially streamlining construction design of the swivel mechanism. Specific modification in the shape of the cam plate (8) and in the design of the guide groove (6) also enables acceleration and deceleration forces to be minimized in the respective end points thereby substantially reducing wear and tear of the device and providing a high degree of operational reliability at reduced cycle times.

    摘要: A twin sheet thermoformer apparatus using hydraulic cylinders to draw the upper and lower platens together for uniform seam forming of the part. A flow divider insures uniform travel of each hydraulic cylinder. An adjustment mechanism enables simultaneous adjustment of the position of four locking shafts on one platen coupled to form locking shafts on the other platen preparatory to operation of the hydraulic cylinders. The adjustment mechanism includes nut members each threaded onto a locking shaft with a recirculating chain engaged with a sprocket on each nut member. Driving the chain enables simultaneous adjustment of each shaft to allow the platen positions to be quickly and accurately adjusted. An encoder generates signals corresponding to the lower platen travel caused by operation of the hydraulic cylinders, which are transmitted to the lower platen drive servo motor to drive the lower platen correspondingly.

    摘要: . A clamping apparatus and method for clamping an injection mold assembly in which clamp assemblies (12, 14) are located only along the parting line (22) between the first (16) and second (18) mold sections of an injection mold unit (10). The clamping assemblies (12, 14) both hold the first and second mold sections (16, 18) in their closed position during the injection molding of a plastic article and separate the first and second mold sections toward their open position after the injection molding of the plastic article. The clamp assemblies (12, 14) being located only at the parting line (20) and in physical contact with both the first and second mold sections (16, 18) eliminate the need for both heavy platens, tie bars and expensive clamping systems of the prior art while providing for uniform or varied clamping pressure where desired along the parting line.

    摘要: Reaction injection molding presses often are very large and require high pressures and special clamping means to prevent leakage from the mold. The press of the invention has fixed platen (11) and movable platen (12) for clamping a composite mold (12/22) therebetween at a closed mold position, plural high pressure hydraulic cylinders (17), mounted on carrier (13) for movable platen (21) and locking mechanism (29) having plural spaced locking positions along locking rods (24) is effective to lock carrier (13) selectively at such positions. A pair of low power hydraulic piston-cylinder assemblies (16) connected with carrier (13) adjacent its opposite ends move the carrier (13) and movable platen (21) to a closed position. Short stroke connecting rods (19) operated by high pressure cylinders (17) are independently movable into engagement with movable platen (21) at plural locations within the area of the composite mold (12/22).

    摘要: A process and an apparatus for manufacturing a product of a thermoplastic resin are disclosed. The apparatus includes a pair of moulds each having a peripheral flange provided with a mating surface. The moulds are clamped by a suitable number of clamp assemblies for clamping the flanges of the moulds so that the moulds are secured together with the mating surfaces in contact with each other. The clamp assembly includes a pair of clamp members (2, 3) for engagement with the flanges of the moulds, a shaft (4) passing through the clamp members, a first stop member (5) provided on the shaft for engagement with one of the clamp members, a spacer (6) provided on the shaft for axial slidable movement and adapted for engagement with the other of the clamp members, a second stop member (8) provided on the shaft for engagement with the spacer at an end opposite to the other of the clamp members. The shaft is made of a material having a coefficient of thermal expansion which is smaller than that of a material from which the spacer is made so that the spacer has a thermal expansion in the axial direction which is not smaller than a thermal expansion in the axial direction of the shaft under the same temperature increase.
