Pneumatic sensor welding pin punching mold capable of realizing convenient material placing

Abstract

The invention discloses a pneumatic sensor welding pin punching mold capable of realizing convenient material placing. The pneumatic sensor welding pin punching mold is characterized by comprising a male mold positioned at the upper side and a female mold positioned right under the male mold, wherein a concave pit matched with the male mold is arranged on the female mold, a bottom mold matched with the male mold is arranged in the concave pit and is arranged on the female mold through a spring, after the spring is compressed, the bottom mold is recessed in the female mold, a position limiting block and a material placing table which are positioned at the two sides of the bottom mold are arranged on the female mold, continuous grooves are respectively formed in the female mold, the bottom mold and the inner wall, near the position limiting block, of the concave pit, the grooves extend on the material placing table for forming material clamping grooves, a groove is formed in the bottom surface of the male mold, the groove formed in the bottom surface of the male mold extends along the side surface, opposite to the position limiting block, of the male mold, and a spray nozzle connected with a high-pressure air source is arranged on the female mold. The pneumatic sensor welding pin punching mold has the advantages that the rejection rate of workpieces is avoided, the product qualification rate is improved, the production time is greatly saved, and in addition, the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a mold used in the sensor manufacturing industry, in particular to a punching mold for pneumatic sensor welding pins which is convenient for discharging. Background technique [0002] The automobile wheel speed sensor is mainly composed of induction head, wiring harness and accessories. The role of the induction head is to cooperate with the target gear installed on the chassis of the car to measure the speed of the car wheel, which is composed of coils, magnetic poles and other parts. On this basis, to ensure the normal operation of the sensor, the sensor must be properly installed on the chassis of the car, and there are many ways to install it. Now commonly used a kind of wheel speed sensor is to rely on the outer steel casing of the induction head to cooperate with a part, i.e. the elastic bush, and pack into the corresponding mounting hole of the chassis. When designing the sensor, it is necessary to combine the magnetic...
