ABSTRACT:
A slide retaining device for an injection mold is disclosed. The slide retaining device has a device body which has a top surface and a bottom surface. A live bearing can be mounted in the device body such that a portion of the live bearing extends above a top surface of the device body. The device is secured such that the live bearing supports the travel of a slide. A shoulder surface is formed where a body head portion interfaces with a body base portion. A spring is disposed is around the body base portion such that a spring top is in communication with the shoulder surface, and a spring bottom extends below the bottom surface of the device body. The spring creates a “pre-load” force that will hold the slide in place. Optional washers can be added to the device to adjust the “pre-load”.
