Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing, in particular to a mold manufacturing hole expanding device. Background Art

[0002] Mould manufacturing is a manufacturing process that uses metal or non-metallic materials as raw materials and uses certain process methods to manufacture moulds to achieve industrial production. During the production process of the mould, holes need to be drilled on its surface to meet the needs of use; mould manufacturing hole expansion is to enlarge the already processed holes. Generally, a larger diameter drilling tool is used to achieve this.

[0003] When the mold is expanding, a lot of debris will be generated. The debris will remain on the surface of the processing table or enter the bottom of the mold, which will affect the flatness of the mold during expansion, resulting in the position of the hole being offset during expansion. In addition, the mold needs to be limited and fixed during expansion. When fixed, usually only one side is set with an adjustable fixing structure. However, different molds need to expand the position of the hole differently, so the adjustable fixing structure at one end will affect the adaptability of the expansion device to the expansion of different molds.

[0004] Therefore, we make improvements on this and propose a hole expanding device for mold manufacturing. Utility Model Content
