Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing, and specifically relates to a punching machine with a positioning structure. Background Technique

[0002] Plastic mold manufacturing refers to manufacturing plastic molds to produce plastic products. A plastic mold is a tool or device used to shape and form plastic products, and a punching machine will be used during the production process of plastic molds.

[0003] A punching machine is a mechanical device used to make holes in materials. It uses a punch to apply pressure and cutting force to the material, shearing or extruding a part of the material to form the required holes.

[0004] When the existing punching machine punches a plastic mold, since the material of the plastic mold is relatively more fragile than metal, a hollow punch will be used to punch the plastic mold. After the punching is completed, some of the materials on the plastic mold will be lifted into the punch, causing blockage of the punch, resulting in the punch being unable to operate normally, blocking the punching operation. Moreover, when the existing punching machine fixes the mold, it is impossible to determine whether the mold is fixed tightly, so it is very easy to occur that it is not fixed tightly, resulting in the plastic mold shifting during the punching process. To solve this problem, we propose a punching machine with a positioning structure. Content of the Utility Model
