Description

Technical Field

[0001] This utility model relates to the field of brake pad pressing molds, and more specifically, to a brake pad pressing mold. Background Technology

[0002] Brake pads, also known as brake discs, are the most critical safety component in a car's braking system. The effectiveness of braking depends entirely on the brake pads; therefore, good brake pads are considered the guardians of both people and vehicles. Brake pads generally consist of a steel plate, an adhesive heat insulation layer, and friction blocks. The steel plate undergoes coating to prevent rust, and the coating process uses an SMT-4 oven temperature tracker to monitor temperature distribution and ensure quality. The heat insulation layer is composed of a non-heat-conducting material for heat insulation. The friction blocks consist of friction materials and adhesive. During braking, they are pressed against the brake disc or brake drum to generate friction, thus achieving the purpose of vehicle deceleration and braking. Due to friction, the friction blocks gradually wear down. Generally speaking, the lower the cost of the brake pads, the faster they wear. The pressing process for brake pads requires the use of pressing molds.

[0003] In existing brake pad pressing molds, such as the one disclosed in patent announcement CN210257354U, a brake pad pressing mold includes a base plate, a lower brake pad pressing mold body, a U-shaped bracket, an upper brake pad pressing mold body, a top plate, and pillars. Pillars are symmetrically arranged on the upper left and right sides of the base plate, with the tops of the pillars positioned at the bottom left and right ends of the top plate. A motor is located in the middle of the bottom of the top plate, with a ball screw connected to the bottom of the motor. A first sleeve is fitted around the outside of the ball screw. The upper brake pad pressing mold body is connected to the bottom of the first sleeve. A second sleeve is fitted onto the pillars, with a first connecting block at the end of the second sleeve near the first sleeve. The lower brake pad pressing mold body is mounted on the U-shaped bracket. This invention, by incorporating an external threaded post, nut, connecting rod, first sleeve, motor, ball screw, controller, second sleeve, first connecting block, L-shaped bracket, and second connecting block, solves the problems of existing brake molds being limited to pressing brake pads of the same specifications and the poor stability of the upper brake pad pressing mold during movement.

[0004] In the aforementioned patent, after the brake pads are pressed by the mold, the brake pads that have been pressed inside are fitted into the mold cavity. When the mold is opened, it is not convenient to quickly unload the material, which affects the processing efficiency. Utility Model Content

Lifting rods 9 are fixedly connected to the upper surfaces of the left and right sides of the positioning strip 7. Lifting blocks 10 are fixedly connected to the upper surface of the lifting rods 9. Through the integrated lifting structure, a lifting component is set at the bottom of the brake pad pressing lower mold and the brake pad pressing upper mold linkage structure. When the brake pad pressing upper mold is lifted, it can automatically drive the bottom top pin to rise and eject the formed brake pad. The ejection is convenient and simple, and the processing efficiency is improved.

[0025] The inner surface of the mold cavity 5 of the brake pad pressing mold 1 is provided with a T-shaped hole, and the inner surface of the T-shaped hole is slidably connected to the ejector pin 6. The ejector pin 6 is distributed on the left and right sides of the mold cavity 5. The ejector pin 6 can be embedded in the mold cavity 5, will not protrude from the mold cavity 5, and will not cause obstruction. When the ejector pin 6 is lifted, the formed workpiece can be lifted through both sides.

[0026] The upper end of the upper mold 2 for pressing brake pads has through holes on both the left and right sides. The outer surface of the lifting rod 9 is slidably connected to the inner surface of the through hole. This facilitates sliding. When the upper mold 2 for pressing brake pads moves up and down, it can slide around the lifting rod 9.

[0027] A flange block 30 is provided on the lower end face of the hydraulic rod of the hydraulic cylinder 3, and is fixedly connected to the upper surface of the brake pad pressing mold 1 through the flange block 30; the installation is firm due to the flange installation.

[0029] The lifting block 10 adopts a circular block structure and is welded and fixed to the upper surface of the lifting rod 9. It is firmly fixed.

When the ejector pin 6 is lifted, the workpiece after being formed can be lifted through both sides. The lifting block 10 adopts a round block structure and is welded and fixed to the upper surface of the lifting rod 9. It is firmly fixed. When lifting, the brake pad presses the upper mold 2, which can drive the lifting block 10 to move upward, drive the lifting rod 9 to move upward, drive the bottom positioning strip 7 and the ejector pin 6 to move upward, and eject the pressed workpiece.

[0031] When the hydraulic cylinder 3 drives the brake pads to press the upper mold 2 down and merge, the lifting block 10 can fall back to its original position after it no longer has upward pressure. The integrated stripping structure is simple in structure and low in cost.
