Abstract
An injection molding machine is provided with a linear guide block configured to be guided on a linear guide rail and a guide mounting block which is secured to the linear guide block and supports the movable platen. Two mounting bolts and two adjust bolts are disposed individually at two positions, spanning between the movable platen and the guide mounting block. The size of a gap between the movable platen and the guide mounting block is adjusted by independently tightening the adjust bolts, whereby the horizontal tilt of the movable platen is adjusted.
Claims2
A movable platen support mechanism of an injection molding machine which comprises a base frame, a stationary platen and a movable platen disposed on the base frame, a linear guide rail secured to the base frame, a linear guide block configured to be guided on the linear guide rail, and a guide mounting block which is secured to the linear guide block and supports the movable platen, the movable platen support mechanism comprising:
- a spring element disposed between the movable platen and the guide mounting block;
- and
- a mounting bolt configured to compress the spring element, thereby elastically connecting the guide mounting block and the movable platen, wherein
- the spring element and the mounting bolt are mounted on the guide mounting block at two or more separate positions longitudinally relative to the linear guide rail, and
- the movable platen is configured to mesh with an adjust bolt which pulls the movable platen, or the guide mounting block is configured to mesh with an adjust bolt which pushes the movable platen.
