Problems solved by technology

[0002] The corners and round holes of automobile molds need to be chamfered. Smaller round holes are usually chamfered by drilling machines or pneumatic grinding wheel tools. Due to the large size of the automobile mold itself, it is inconvenient to carry and prolongs the production cycle of the mould. The cost of drilling machine equipment is high, the pneumatic grinding wheel needs an air source to drive, and the chamfering efficiency is low, resulting in high production costs

Abstract

The car mold round hole chamfering device includes a drill bit, a drill handle and a casing. The two ends of the drill handle are respectively connected to the drill bit and the casing. A spiral groove body, the spiral groove body is matched with the sliding sleeve, and a spring is connected to the end of the spiral groove body. The present invention does not require too much cutting force, so it does not need more pneumatic tools for preparation, and can conveniently chamfer the round hole of the automobile mold anytime and anywhere, so that the chamfering efficiency is greatly improved and the cost is also greatly reduced.

Description

technical field [0001] The invention relates to the field of automobile molds, in particular to an automobile mold round hole chamfering device. Background technique [0002] The corners and round holes of automobile molds need to be chamfered. Smaller round holes are usually chamfered by drilling machines or pneumatic grinding wheel tools. Due to the large size of the automobile mold itself, it is inconvenient to carry and prolongs the production cycle of the mould. The cost of drilling machine equipment is high, the pneumatic grinding wheel needs an air source to drive, and the chamfering efficiency is low, resulting in high production costs. Contents of the invention [0003] The technical problem solved by the present invention is to provide an automobile mold round hole chamfering device to solve the above-mentioned shortcomings in the background technology. [0004] The technical problem solved by the present invention adopts following technical scheme to realize: ...
