Abstract

The invention belongs to the field of car part machining molds, and particularly discloses a car U-shaped plate manufacturing mold. The car U-shaped plate manufacturing mold comprises a rack, a movable mold and a fixed mold are arranged on the rack, a hydraulic cylinder is fixed to the rack, the movable mold comprises a pressing plate connected to the bottom end of a piston rod of the hydraulic cylinder, bending punches are connected to the two sides of the pressing plate, a U-shaped mold cavity is formed between the pressing plate and the bending punches, the fixed mold comprises a positioning seat and a base, the positioning seat is matched with the mold cavity in size, a sleeve is arranged in a first through hole, a second air inlet pipe is communicated between the side wall of the sleeve and a cold air outlet end, a second air inlet one-way valve is arranged in the second air inlet pipe, a piston is in sliding connection into the sleeve, the lower side of the piston is fixedly provided with a first connecting rod, a groove communicating with the first through hole is formed in the bottom of the positioning seat, an air bag communicated with the sleeve is arranged in the groove,and a protruding part is arranged on the air bag. According to the scheme, the problem that a machined U-shaped plate is not prone to taking down, and the rejection rate is high is solved.

Description

technical field [0001] The invention belongs to the field of molds for processing automobile parts, and specifically discloses a mold for making automobile U-shaped plates. Background technique [0002] Die refers to a tool that can form a blank into a product of a specific shape and size under the action of external force. Among them, most of the auto parts are processed by stamping die. Stamping die refers to applying deformation force to the plate at room temperature to obtain a certain shape, size and performance. Special special tools for product parts. As a commonly used metal connector in the assembly process of auto parts, the U-shaped plate is processed through a stamping die. [0003] Usually, the stamping die has a specific contour or inner cavity shape, and is mainly composed of a movable die and a fixed die. The plate is placed on the fixed die, and then the movable die is driven to move relative to the fixed die. When the movable die and the fixed die are in c...
