Upper punching structure for continuous deep drawing or molding die

Abstract

The invention discloses an upper punching structure for a continuous deep drawing or molding die. The upper punching structure comprises a drawing molding upper die and a drawing molding lower die, wherein the drawing molding lower die is provided with a punching male die, the drawing molding upper die is provided with a punching female die corresponding to the punching male de, when in die assembly, a punching material removing block is pressed down by the punching female die so that the punching male die stretches out to cooperate with the punch female die so as to complete upper punching operation after drawing molding. Under the premise of not changing the original drawing or molding direction, the punching direction is changed so as to guarantee the strength of the punching female die to guarantee the die to be produced stably, the problem of waste discharge is solved through a blowing manner, and the upper punching structure has the advantages of reasonable structure, stability in product machining, and the like.

Description

technical field [0001] The invention discloses an upper punching structure for a continuous drawing or forming mold, which belongs to the technical field of continuous mold manufacturing according to the International Patent Classification (IPC). Background technique [0002] Traditional mold punching generally adopts the way of punching down, that is, the punch moves up and down to realize the punching operation, while the continuous die usually uses the way of punching down, such as the Chinese document CN201210393450.2 Punch continuous die, including An upper mold, a lower mold and a base, the upper mold is provided with punches for punching, the lower mold is provided with inner guide posts, and the lower mold is provided with punching holes corresponding to the punches. However, for some products, such as electronic lead frames, it needs to be stretched or formed first, and then punched. The direction of stretching or forming has to be changed, but such a mold structur...

Problems solved by technology

However, for some products, such as electronic lead frames, it needs to be stretched or formed first, and then punched. The direction of stretching or forming has to be changed, but such a mold structure changes the already stable and recognized stretching or forming direction, and it will add difficulty or unstable factors to stretching or forming

[0003] The discharge of waste after punching of continuous stretching or forming molds is a major problem in the industry. Since the waste cannot be discharged in time, it affects the normal operation of the mold
