Guide shoe for a guiding device of a plastic processing machine clamping unit

Abstract

The invention relates to a guide shoe (1) of a guiding device of a plastic processing machine clamping unit for supporting and guiding a moving mold platen (30) in the clamping direction of the plastic processing machine. The guide shoe (1) has a main part (2) which is elongated in the clamping direction and on which sliding and / or rolling elements can be fixed, and the guide shoe has a connecting element (10) which is spaced from the main part (2), which runs in a substantially vertical manner in the clamping direction (x direction), and which has a fixing region (12) for fixing the guide shoe (1) to a moving mold platen (30), wherein - the moving mold platen (30) can be fixed solely to the fixing region (12) of the connecting element (10) in a decoupled manner from the main part (2), - the connecting element (10) is designed as a deformation element (10), and - the deformation element (10) is fixed to the main part (2) via a connecting region (18) that forms a target bending zone with respect to a bend about a bending axis (B), which is substantially parallel to the clamping direction, such that the deformation element (10) additionally forms a target torsion zone about a torsion axis (T), which is substantially perpendicular to the clamping direction.

Description

Technical field [0001] The invention relates to a guide seat for a closing unit of a plastic processing machine, in particular a guide device for a closing unit of a double-plate injection molding machine with a stretching column. The present invention will be exemplarily described below with the aid of an injection molding machine. However, the present invention is not limited to this and can be transferred to other plastic processing machines with linearly guided closing units. Background technique [0002] In the injection molding machine, the two mold halves of an injection tool are housed by a fixed mold clamping plate and a movable mold clamping plate. These mold clamping plates move towards each other or move apart from each other during the injection cycle. Here, the fixed mold clamping plate is fastened to the injection molding machine in a fixed position. The mold can be opened and closed by the movable mold clamping plate. Therefore, the direction of movement of the...

Problems solved by technology

This complex design of the movable mold clamping plate not only leads to high manufacturing costs for the injection molding machine, but also results in a bulky and expensive design of the movable mold clamping plate, and thus high acceleration forces or deceleration force is required

[0021] This in turn leads—if one does not wish to endure prolonged cycle times—to considerably larger and more powerful drive units, which additionally increase the costs of the injection molding machine and impair the energy balance
