摘要： A mold clamping device includes a base, a stationary platen fixed to the base and supporting a stationary mold, a movable platen movable on the base and supporting a movable mold, and a mold clamping mechanism for clamping the movable mold against the stationary mold. Tie bars extend from the stationary platen completely through both the movable platen and the mold clamping mechanism. A shaft supporting plate is fixed to the ends of the tie bars and terminates at its lower end portion in two spaced-apart shoes that have flat bottom surfaces in direct sliding contact with the base. The flat bottom surface of each shoe has a larger area than the cross-sectional area of the shaft supporting plate situated vertically above the shoe.

摘要： A plastic injection molding machine and molding method related to an injection molding machine for stack molds, wherein the central portion of the mold remains fixed and it has two molding faces that act on the fixed central portion by means of a hydraulic chamber that produces the clamping force and prevents the deformations due to bending on the molding faces. Likewise, it relates to a molding method.

摘要： A mould-closing unit for an injection moulding machine for processing plastics has a mould support which is movable relative to a stationary mould support (10). A mould-moving device is provided to move the movable mould support into and out of closure of an injection mould. At least one force transmission element is connected to the movable mould support and at its end remote from the movable mould support has a section (14a) which is assigned to the stationary mould support (10) and can be actuated for operative engagement. The stationary mould support (10) is assigned a locking device (15), which can be moved into interlocking operative connection with the actuatable section (14a) to apply a closing force during closure of the injection mould. According to the method, these elements are used to create a method for locking a force transmission element to a mould support of the injection moulding machine. The fact that the locking device (15) has floating clamping jaws (16) which can be moved into interlocking operative connection with the actuatable section (14a) during closure of the mould to lock the force transmission element and the stationary mould support (10) and at the same time are connected to at least one piston (18) of a piston-cylinder unit (17) for applying the closing force, means that a mould-closing unit is created in which the locking mechanism for locking the tie bars to the mould support is integrated in a common unit with the unit for applying the closing force.

摘要： Provided is a mold clamping device that can simplify the component count or structure by including a mold thickness adjustment mechanism that reduces the load on a power source, is easily maintained, and has high design flexibility. Also provided is a mold clamping device that can set a long distance (daylight) between molds without having to upsize the entire mold clamping device and can simplify the component count or structure.
A mold clamping device for split molds includes a first platen, a second platen, a pressure receiving platen, and a mold thickness adjustment mechanism disposed on the pressure receiving platen. At least one of the first platen and the second platen is able to move back and forth so as to approach or depart from the other. The pressure receiving platen is located on a side remote from the first platen, of the second platen. The mold thickness adjustment mechanism includes a rod-shaped rotation member, a power source configured to rotate the rotation member around a rotation axis of the rotation member, the rotation axis being parallel to a longitudinal direction of the rotation member, and a pair of converters configured to convert rotation direction of the rotation member into a movement direction of the second platen. A mold clamping device for split molds includes polygonal first and second platens, a pressure receiving platen, and a toggle mechanism. At least one of the first platen and the second platen is able to move back and forth so as to approach or depart from the other. The pressure receiving platen is located on a side remote from the first platen, of the second platen. The toggle mechanism is disposed between the second platen and the pressure receiving platen and on a diagonal line of the second platen and configured to cause the first and second platens to approach or depart from each other.-

摘要： A toggle mold closure assembly for injection presses includes: fixed, mobile and reaction planes, mounted on columns; a control unit of the toggle, having four pairs of levers, arranged symmetrically at two sides, in upper and lower parts of the structure, interconnected by a pin and to the reaction plane and mobile plane by respective pins; and an actuation unit of the control element. The control unit is placed on the axis of the toggle in the middle of the pairs of main side levers, which have an outward movement. The control unit is connected, by control connecting rods, to the levers of the toggle connected to the reaction plane, and is placed between the central connection pin of the levers and the reaction plane. The control unit is provided with heads for connection to the connecting rods external to the reaction plane and turned towards the reaction plane.

摘要： The clamping device has tie bars which are connected to a fixed platen and have engaged parts at a movable platen side, clamping cylinders which are provided on movable platens, half nut devices which are connected to pistons of the clamping cylinders and can mesh with the engaged parts, and stopper devices which restrict the movement of the half nut devices. Each stopper device has at least a driving unit and a stopper part which is driven in a mold opening and closing direction relative to the movable platen by driving of the driving unit and can engage with the half nut device from the fixed platen side. No winding transmission mechanism is interposed between the driving unit and the stopper part.
