Special trimming machine for high-precision laser positioning die ejector rod

Abstract

The invention provides a special trimming machine for a high-precision laser positioning die ejector rod. The special trimming machine comprises an angle grinder, an angle grinder mounting block and an angle grinder dismounting block. Two main and auxiliary connecting rods are arranged, the left ends of the main and auxiliary connecting rods are connected to the inner wall of the right side of a cutting head main board, the right ends of the main and auxiliary connecting rods are connected to the inner wall of the left side of a cutting head auxiliary board, the bottoms of the cutting head main board and the cutting head auxiliary board are respectively sleeved and fixed on the outer end surfaces of the left side and the right side of a rotating shaft, the left end and the right end of therotating shaft are rotatably connected in two bearings correspondingly, and a pressing handle is mounted on the top end face of the angle grinder mounting block. Linear laser light is projected to agrinding groove part through a linear laser marker, the rotary trimming portion of the angle grinder is marked, so that personnel can adjust the position of the ejector rod inside a grinding groove according to the laser projection part of the linear laser marker, and the grinding precision of the ejector rod is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mold ejector pin processing, and more specifically relates to a special mold repairing machine for high-precision laser positioning mold ejector pins. Background technique [0002] In the mold production process, the grinding of the ejector pin is a necessary process for each set of molds. [0003] The model repairing machine can refer to the CN207901075U patent, which mainly includes a workbench, at least one mold repairing mechanism on the workbench, a storage box on the workbench, a cabinet under the workbench, and a cabinet located on the workbench. The hook on at least one side of the workbench; the mold repairing mechanism includes a roller frame, a roller mounted on the roller frame, a fastening screw connecting the roller frame and the roller, and its number is two, two The distance between the rollers is adjustable, the surface of the rollers is provided with a rough structure, and the rough str...

AI Technical Summary

Problems solved by technology

[0004] When the existing similar mold repairing machines are in use, the grinding effect on the ejector rod is poor, and it mostly relies on the workers to operate the ejector rod. It is cumbersome; and the flatness and dimensional accuracy of the ejector rod after grinding have large errors, which cannot meet the requirements for mold production and processing.
