Description

Technical Field

[0002] Molds are various molds and tools used in industrial production to obtain the desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In the mold production process, it is usually necessary to drill holes in the mold using a drilling device to facilitate the assembly and installation of the mold.

[0003] Since molds are not all regular cuboids, some molds may have inclined surfaces (as shown in the instruction manual). Figure 5 In molds, these inclined surfaces sometimes need to be drilled to install auxiliary accessories (or for assembly requirements). Most existing drilling equipment drills are perpendicular to the horizontal plane. When drilling holes in the inclined surfaces of the mold, it is difficult to ensure that the drill bit is perpendicular to the inclined surface of the mold, which easily results in the drilled holes being inclined, which in turn makes it impossible to install auxiliary accessories or assemble the mold.

[0004] Therefore, a die-punching device for mold manufacturing is proposed. Utility Model Content
