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

[0028] The following are the common points of the embodiments:

[0029] The closing unit has a movable mold clamping plate 2 and a fixed mold clamping plate 12 assembled on the base 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 realization). 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 profile. If the nut is closed, the inner contour engages the outer contour of the beam 8, thereby forming a form fit. The pressure pad 9 is assembled on the side of the fixed mold clamping plate 12 away from the movable mold clamping plate 2. The pressure pad is constructed hydraulically. Its piston part is configured to be connected to the beam 8 or formed by these beams. By making th...

Abstract

The present invention relates to a vertically closed closing unit used for a molding machine. The closing unit is equipped with a movable die clamping plate 2 and at least one motor 3 used for enabling the movable die clamping plate 2 to move relative to a machine base 4, at least two individual conversion devices 5 are arranged in the closing unit and are used for converting the output motion of the at least one motor 3 into the clamping plate motion of the movable die clamping plate, and a synchronizing device 6 is also arranged to synchronize the clamping plate motion an / or the output motion, wherein the at least one motor 3 is a hollow shaft motor, and the synchronizing device is electronic. The present invention also relates to the molding machine possessing the closing unit.

Description

Technical field [0001] The present invention relates to a vertical closing unit for a molding machine having the features described in the preamble of claim 1 and a molding machine with the closing unit. Background technique [0002] JP2005231139A and JPH08229969A respectively disclose a vertical closing unit for an injection molding machine, and their electric quick-action reciprocating device has a screw drive device. [0003] Here, "molding machine" can be understood as an injection molding machine, a die casting machine, a press, and the like. [0004] A closed unit for a rubber die casting machine is disclosed in DE19848391A1. The rubber die-casting machine has a vertically closed closed unit, in which an electric motor is arranged for moving a movable mold clamping plate relative to the machine base. [0005] The disadvantage here is that the force applied by the electric motor for moving the movable mold clamping plate is introduced eccentrically into the mold clamping plate. ...
