Abstract
A compensating device for an injection molding machine is provided which enables the moveable mold part to be supported on stationary platen guide rails of the molding machine, thereby relieving the bending force normally applied by the moveable mold part on the platen bearings and avoiding bearing wear. The compensating device is constructed to permit multiple directional adjustment, including vertical mold adjustment to permit existing bearing wear to be compensated for.
Claims20
A device for use with an injection molding machine comprising a stationary mold part and a moveable mold part mounted on a platen for sliding movement on upper and lower horizontal rails into and out of mold cavity-forming relationship with said stationary mold part for compensating for a bending force on platen bearings produced by the moveable mold part, which comprises:
- a body member for mounting to the moveable mold part,
- cam means mounted in said body member for applying a camming action to the moveable mold part when the body member is mounted to the moveable mold part, and
- a slide member mounted to said body member for mounting said body member in sliding relation to the lower horizontal rails.
In an injection molding machine which comprises a stationary mold part and a moveable mold part mounted on a platen for sliding movement on upper and lower horizontal rails into and out of mold cavity-forming relationship with said stationary mold part, the improvement which comprises:
- means mounted to said moveable mold part and received in sliding relationship to said lower horizontal rails for compensating for a bending force on platen bearings produced by said moveable mold part.
