Problems solved by technology

As the size of the horizontal injection molding machine becomes larger and larger, the overturning moment to be supported is also larger and larger; however, the linear guides with dovetail groove cross-sections required for this are quite expensive and cannot be used in large horizontal injection molding machines. cannot be used in

Embodiment Construction

[0011] The invention is described with the aid of a two-platen horizontal injection molding machine. A fixed mold clamping plate 2 is fixed on a frame 1, while a movable mold clamping plate 3 is movably mounted on solid slides 4 and suitable linear guides. The movable mold clamping plate 3 can be moved by means of hydraulic servo drives 5 and 6 arranged diagonally to one another. These servo drives are fixed on the one hand (for example with cylinders 5a, 6a) on the respective supports 7 and 8 connected to the frame and on the other side (for example with their piston rods 5b, 6b) on the movable mold clamping plate 3. However, the hydraulic servo drives 5 and 6 can also be arranged between the fixed and movable mold clamping plates. The mold clamping plate 3 itself consists of the inherent mold clamping plate 3a and a pressure plate 3b, between which four pressure pads for applying the closing pressure are arranged, of which only the rear pressure pads can be seen in the figu...

Abstract

The invention relates to a horizontal injection moulding machine, in particular a double-plate injection moulding machine, comprising a fixed (2) and a displaceable (3) mould clamping plate with columns (11a, 12a, 11b, 12b) that run between the two mould clamping plates and a base plate (18), which is situated between the mould clamping plates (2, 3) and which can be displaced parallel to the longitudinal axis of the machine by means of first drive elements (19, 20). A rotary table (21) is rotatably mounted on said base plate to rotate about a vertical axis and mould-half carriers (23) for the mould halves (24a, 25a) of injection moulding tools are fixed to said rotary table (21). The invention is characterised in that the machine is equipped with a yoke (30), which extends between the upper columns (11a, 11b), can be displaced in relation to the latter and comprises a recess, that a pivot pin (26) is provided on the upper face of the central mould-half carrier, said pin being rotatably mounted in the recess of the yoke (30) and that additional drive elements (32, 33) are provided on both sides of the pivot pin (26) between the yoke (30) and one of the two mould clamping plates (2, 3) for displacing the yoke (30) in relation to the latter (2, 3). The yoke (30) is preferably supported on the central mould-half carrier (23).

Description

Technical field [0001] The present invention involves a horizontal injection molding machine with a moving backing device for each mold semi -body semi -body for each injection mold. Background technique [0002] WO 01 / 010624 revealed a dual -boarded injection molding machine with a fixed mold clamping board with some activity on some pillars and a setting between two mold clamping boards and can be parallel parallel in parallel in parallel in parallel onThe rotation device that can be used for injection molds by the vertical axis of the machine and can turn around a vertical axis.The rotating device includes a bottom panel that moves along the vertical axis of the machine by the first driver, and a turntable is set on the bottom plate. The turntable can be rotated around the vertical axis with the second drive device.In order to move the bottom plate, hydraulic servo drivers are usually set, and they are fixed on the bottom plate and the other side is fixed on the rack and fixe...
