Composite machining die for switch shaft aluminum post

Abstract

The invention discloses a composite machining die for a switch shaft aluminum post. The composite machining die comprises an upper die and a lower die, wherein a casting groove consistent with a switch shaft in outline dimension is formed in each of the lower die and the upper die; a lug boss used for forming the inner cavity of the switch shaft is arranged at the top end of the casting groove of the lower die and is a replaceable metal post; the top end of the metal post is fixed through a connecting base; the connecting base is connected by a fine tuning control rod arranged on the outer side of the lower die. The composite machining die is ingenious in concept; due to the fact that the replaceable lug boss metal post is arranged on the connecting base, the application range of the die is widened, and the developing cost of the die is reduced; meanwhile, due to the fact that the fine tuning control rod is arranged on an indirect base, the metal post is adjusted by the fine tuning control rod to form the depth of the inner cavity of a casting, fine tuning can be performed in a production process, and an error caused when the metal post is used for a long time can be overcome.

Description

technical field [0001] The invention relates to a cast aluminum processing mold, in particular to a composite processing mold for an aluminum column of a switch shaft. Background technique [0002] The switch shafts commonly used in the mechanical switches of lamps are processed by aluminum casting process. The traditional aluminum casting process needs to develop corresponding casting molds according to different structures and sizes. In actual production, because a certain series of switch shafts only Because of the change of local dimensions, it is often necessary to develop multiple sets of molds to correspond to the production, which virtually increases the manufacturer's production cost investment. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a compound processing mold for the aluminum column of the switch shaft in view of the above shortcomings of the prior art. The column is cast to improve the proces...
