Machining method of pitched roof via hole hanging table

Abstract

The invention relates to a machining method of a pitched roof via hole hanging table. Process grooves are preformed in two joined side surfaces of a hanging table and a via hole; and after leads are inserted in the groove processes, a linear cutting slow wire feeding process is adopted to machine left and right two side surfaces of the hanging table and the inner wall, near the left and right two side surfaces of the hanging table, of the via hole. As the left and right two side surfaces of the hanging table and the left and right inner walls of the via hole are separately machined, and both adopt the linear cutting slow wire feeding process, round angles corresponding to cutters cannot be generated in the joined positions, the joined positions of the hanging table and the via hole can be more smooth, the machining quality of the pitched roof via hole hanging table is effectively improved, and the rework condition is prevented.

Description

technical field [0001] The invention relates to the technical field of injection mold manufacturing, and more specifically, relates to a processing method of a slanted top through-hole hanging platform. Background technique [0002] The inclined top mechanism is a commonly used name in the mold industry. It is a mechanism used to form barbs inside the product in mold design. [0003] The inclined ejector mechanism consists of ejector bottom plate, ejector panel, male formwork and rear mold core from bottom to top. The bottom end of the rod-shaped inclined ejector seat is fixedly connected with the ejector base plate, and passes through the ejector base plate and ejector panel, and its top is located inside the male formwork. , the bottom end of the inclined top body is slidingly connected with the inclined top seat, and the top end penetrates into the rear mold core. [0004] In the actual production process, the slanted ejector seat moves up and down driven by the thimble ...

AI Technical Summary

Problems solved by technology

[0005] like figure 1 As shown in , when the slanted top via hole hanging table is currently being produced, CNC rough machining is used first, and then the left and right inner walls of the via are processed by wire cutting and slow wire-feeding. However, there are multiple holes between the inner wall of the via hole and the hanging table. The joint position forms a corner at the joint position, and there will be a rounded corner corresponding to the tool at the corner part M processed by CNC, so EDM (Electrical Discharge Machining) must be used to process the rounded part in the future. However, , after EDM processing, the hanging table and wire cutting parts are difficult to connect, which often leads to rework, seriously affecting product quality and production efficiency

[0006] Therefore, how to improve the processing quality of the slanted top through-hole hanging table and avoid rework as much as possible is a technical problem that those skilled in the art need to solve urgently.
