Description

Technical Field

[0001] The utility model relates to the technical field of brake pad molds, in particular to a general mold for brake pad backplate samples. Background Technique

[0002] The brake pad is the most critical safety part in the vehicle braking system. The brake pad plays a decisive role in the quality of all braking effects. Generally, the brake pad is composed of a steel plate, an adhesive heat insulation layer and a friction block. The steel plate needs to be painted to prevent rust. The friction block is composed of a friction material and an adhesive. When braking, it is squeezed against the brake disc to generate friction, so as to achieve the purpose of vehicle deceleration and braking. With the continuous improvement of the living standards of human beings, the demand for automobiles gradually increases, and the demand for brake pads also increases accordingly. The brake pads are mass-produced through molds. At present, the stability of the molds themselves is not strong. After long-term use, the upper die base and the lower die base cannot be fully meshed for manufacturing, which greatly reduces the service life of the molds. It is possible to enhance the stability and balance of the molds themselves to ensure that the brake pads can be continuously manufactured in a balanced and stable manner, improve the utilization rate of the molds, and it is impossible to install and disassemble the samples of the molds and replace them. It is possible to add the installation and disassembly function to improve the flexibility and diversity of the brake pad molds. It is impossible to eject the manufactured molds upward, which is inconvenient for taking. It is possible to add an ejection function to quickly eject the manufactured molds upward for easy taking.
