Abstract

The invention discloses a mould ejection rod anti-rotation locating device which comprises an ejection rod, an ejection plate, nuts and threads. The device is characterized in that the device further comprises a rectangular locating block and an anti-rotation rectangular slot; the end part of the ejection rod is inserted into a ladder platform on the ejection plate from the top down and mounted on the ejection plate; the rectangular locating block is inserted into the anti-rotation rectangular slot from the lower end face of the ejection plate; the threads are screwed upwards by the nuts from the lower end of the ejection rod to allow a position of the ejection rod on the top plate to be fixed. The device has the benefits that the problems that the anti-rotation ejection rod is difficult to manufacture, assemble and replace are solved effectively.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a device for anti-rotation positioning of a mold ejector pin. Background technique [0002] The design of the traditional anti-rotation positioning method of the ejector rod is relatively complicated, which brings great inconvenience to the production, assembly, and maintenance. It is generally composed of the ejector rod, the top plate, and the splint. The anti-rotation positioning structure in the prior art mainly has the following technical problems: [0003] Difficult to manufacture: the ejector rod needs to be made of round steel in a "T" shape, the main body is cylindrical, and the end is made into a cuboid, and both of them need to have a positional and dimensional accuracy requirement of 0.05mm, so the production of the anti-rotation ejector rod is very difficult , high production cost; in order to achieve anti-rotation positioning effect. It is necessary to process...
