Grinding head for repairing mold

Abstract

The invention discloses a grinding head for repairing a mold. The grinding head comprises a shell, a worm gear, a motor, a grinding head body, a worm, a second gear tower, a first gear tower, a bevel gear, a hand wheel, a driven gear, a driving gear and a sliding frame. The shell is a supporting body, the motor drives the grinding head body to rotate, and feeding and retreating of the grinding head body can be achieved by rotating the hand wheel; the worm gear, a threaded shaft, a moving shaft, a fourth bevel gear, the worm, a third bevel gear, a second gear tower, a first gear tower, a second bevel gear, the hand wheel, a rear cover, a first bevel gear, a driven gear, a driven pinion, a second retaining rod, a transmission pinion, a driving gear, a driving pinion, a retaining piece, a first retaining rod, a pull rod, a spring, a shifting rod and a sliding frame form a five-gear variable-speed transmission mechanism capable of adjusting the transmission ratio according to feeding requirements, high-speed gear feeding can be adopted during idle stroke, the moving time of the grinding head is shortened, low-speed gear feeding can be adopted when the surface of the mold is trimmed, and the machining quality of the surface of the mold is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a grinding head used for repairing molds. Background technique [0002] Molds play an extremely important role in modern industry, and the quality of molds directly determines the quality of products. my country's mold industry has developed rapidly in recent years and has become one of the top three mold producing countries in the world. However, there is still a big gap between my country's mold industry and foreign advanced mold production levels, mainly in the long manufacturing cycle, low manufacturing precision, and mold production. In terms of short life, the problem of short mold life is particularly prominent, which directly leads to the waste of resources and the increase of production costs. Therefore, repair and reuse the failed molds to prolong the use time of the molds, thereby recovering unnecessary losses in production , will greatly promote the development of ...
