Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example 1: an injection tooling die change structure, referring to fig. 1, comprises an upper boosting plate 2 and a lower boosting plate 1. The lower boosting plate 1 is horizontally arranged and fixed on a rack of the injection molding machine, and the length direction of the lower boosting plate 1 is arranged along the replacement moving direction of the injection tool. The upper booster plate 2 is located above the lower booster plate 1, and is slidably connected to the lower booster plate 1 in the longitudinal direction of the lower booster plate 1. Go up boost plate 2 and be used for supporting injection frock, through sliding last boost plate 2, and then with injection frock propelling movement to the set position, perhaps push away the injection frock from the set position.
