Description

Technical Field

[0001] This utility model belongs to the field of molding die technology, and in particular relates to a vehicle-mounted EPB embedded forming gear die. Background Technology

[0002] The Electronic Parking Brake (EPB) system is a technology that uses electronic control to achieve parking braking. This system combines temporary braking during driving with sustained braking after parking. The EPB system controls the parking brake through electronic circuitry, functioning similarly to a traditional mechanical lever handbrake, but offering a more convenient and safer operating method. When starting the vehicle, the driver does not need to manually release the electronic parking brake; it will automatically disengage once the accelerator is pressed.

[0003] EPB gears refer to the gear transmission components used in the Electronic Parking Brake (EPB) system of automobiles. The EPB system utilizes an electric motor to drive the external and internal gear mechanisms to rotate. Because these two mechanisms rotate in opposite directions, they can drive the connected cable to move, thus completing the parking function. This gear mechanism acts as a force transmission medium, converting the rotational motion of the electric motor gears into tension.

[0004] In existing technology, EPB gears are manufactured using injection molding. However, existing molds have some defects, primarily concerning the accuracy of the embedded parts' installation position on the gear injection mold. These defects can lead to performance instability or shortened lifespan during gear use. Therefore, to ensure gear quality and performance, existing molds need to be improved to ensure accurate installation of the embedded parts. Utility Model Content
