Problems solved by technology

[0005] A disadvantage here is that the force exerted by the electric motor to move the movable mold clamping plate is introduced eccentrically into the mold clamping plate
Especially in the case of large closing units, the problem arises in that the parallelism of the plates or of the mold halves mounted on the clamping plates is not sufficiently parallel

Embodiment Construction

[0026] The following are common to the examples:

[0027] The closing unit has a movable mold clamping plate 2 and a fixed mold clamping plate 12 mounted on a frame 4 . The four beams 8 are guided through the movable mold clamping plate 2 and the fixed mold clamping plate 12 (this is done by means of the through holes provided in the movable mold clamping plate 2 and the fixed mold clamping plate 12 Bushing implementation). The movable mold clamping plate 2 can be locked relative to the beam 8 by means of a locking device 11 . This is achieved by means of a split nut with an inner contour. When the nut is closed, the inner contour engages with the outer contour of the beam 8 , thus forming a positive fit. The pressure pad 9 is mounted on that side of the fixed mold clamping plate 12 remote from the movable mold clamping plate 2 . The pressure pad is configured hydraulically. Its piston part is formed in connection with beams 8 or via these beams. The closing force is exe...

Abstract

The invention relates to a vertically closing closing unit for a molding machine, said closing unit having a movable mold clamping plate (2) and at least one device for positioning the movable mold clamping plate (2) relative to a motor (3) for the movement of the frame (4), in which at least two separate conversion devices (5) are arranged in said closed unit for converting the output motion of said at least one motor (3) into a movable The clamping plate movement of the mold clamping plate (2) is provided with a synchronization device (6) for synchronizing the clamping plate movement and / or output movement, wherein at least one electric motor (3) is designed as a hollow shaft motor , and the synchronization device (6) is constituted electronically. The present invention also relates to a molding machine with said closing unit.

Description

technical field [0001] The invention relates to a vertical closing unit for a forming machine and to a forming machine having said closing unit. Background technique [0002] JP2005231139A and JPH08229969A each disclose a vertical closing unit for an injection molding machine whose electric snap-action reciprocating device has a screw drive. [0003] Here, "molding machine" can be understood as an injection molding machine, a die casting machine, a press, and the like. [0004] A closing unit for a rubber die-casting machine is disclosed in DE 19848391 A1. The rubber die-casting machine has a vertically closed closing unit in which an electric motor is arranged for moving a movable mold clamping plate relative to a machine base. [0005] A disadvantage here is that the force exerted by the electric motor to move the movable mold clamping plate is introduced eccentrically into the mold clamping plate. In particular in the case of large closing units, the problem arises in ...
