Abstract

The invention provides a die for processing a movable piece and further provides a production method for the die. By the adoption of the die and the production method, the precision of continuous processing can be ensured, the phenomenon of scrap jumping up can be effectively prevented, and the quality of products can be improved. The die comprises an upper die base and a lower die base. An upperdie backing plate, an upper die plate, a discharging back plate, a discharging plate, a lower die plate and a lower die backing plate are sequentially arranged between the upper die base and the lowerdie base. Embedding holes with different sizes are formed in the lower die plate in the strip length direction. Female die inserts are detachably arranged in the embedding holes. The female die inserts are adapted to a processing part of the movable piece in shape and size, and a cutting edge is arranged on each female die insert. A chute for preventing material jumping in the edge line of the cutting edge is formed in the inner wall of each female die insert. A male die on the upper die plate corresponds to each female die insert.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a mold for processing a movable piece and a preparation method of the mold. Background technique [0002] As one of the key components of the on-board relay, the movable piece transmits current through the contacts on the movable piece to control the input and output of signals. It has a bent three-dimensional shape, small size, light weight, and high precision requirements. During processing, it is necessary to bend the final formed flat metal sheet into shape, so the requirements for processing molds are relatively high. [0003] The concave mold in the existing movable connecting plate processing mold is generally a fixed one-piece type. During the mass production process, the concave mold is prone to wear and tear as the processing progresses, resulting in a decrease in precision, thereby affecting the quality of the product. In the process of processing, due to the ...
