Referring to fig. 1 to 4, a positioning structure for preventing rotation of a mold ejector includes an ejector 21 and a positioning block 31.
As shown in fig. 1 and 2, the ejector pin 21 is installed in the mold 11, and the specific shape of the ejector pin 21 can be seen in fig. 3, in this embodiment, the ejector pin 21 is provided with at least one positioning plane 22, and the positioning plane is disposed on the peripheral surface of the ejector pin 21. The positioning block 31 is mounted on the mold 11 by a fastening assembly, and the positioning block 31 abuts against the positioning plane 22 so that the ejector rod 21 does not rotate.
It can be understood that, with reference to fig. 3 and 4, after the positioning block 31 abuts against the positioning plane 22 of the ejector rod 21, even if the fixing screw of the ejector rod is loosened under stress, the ejector rod 31 cannot rotate, that is, radial offset cannot occur.
Specifically, the ejector rod 21 passes through a guide hole of the mold 11, and the positioning block 31 is installed near the guide hole. Wherein, the locating plane 22 is provided with one, and the cross section of the mandril 21 at the position where the locating plane 22 is arranged is D-shaped.
