Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a processing mold for a sealing cover plate of an automobile gearbox. Background Art

[0002] The sealing cover plate of the automobile gearbox is a key component, located on the outer shell of the gearbox, used to seal the lubricating oil or liquid inside the gearbox to prevent leakage and protect the internal mechanical parts from the external environment. The sealing cover plate is usually made of metal materials, such as aluminum alloy or steel, to ensure that it has sufficient strength and durability. It usually has several important features and functions: Sealing performance: The main function of the sealing cover plate is to ensure that the lubricating oil or liquid in the gearbox does not leak into the external environment. Therefore, the sealing cover plate must have good sealing performance to prevent oil leakage and avoid damage to mechanical parts due to lack of lubrication. Mounting interface: The sealing cover plate usually has a mounting interface that matches the gearbox housing for easy installation and fixing on the gearbox. These interfaces may include bolt holes, gasket grooves, etc. to ensure a tight connection between the sealing cover plate and the gearbox housing. Heat dissipation function: Since the gearbox generates heat when working, the sealing cover plate is usually also designed with a heat dissipation function to help dissipate the heat inside the gearbox and maintain a proper working temperature. This may include designs such as heat dissipation grooves and heat dissipation fins to help improve the cooling effect of the gearbox. Durability and corrosion resistance: Since the sealing cover is located at the bottom of the car and is exposed to various harsh road conditions and environments, it must have good durability and corrosion resistance. The sealing cover is usually treated with rust-proof treatment or special coating to increase the corrosion resistance of its surface and ensure that it will not be damaged during long-term use. Lightweight design: With the development of lightweight technology for automobiles, sealing covers are also increasingly inclined to adopt lightweight designs to reduce the overall weight of the car and improve fuel efficiency and performance. Therefore, the use of lightweight materials and optimized structural design are usually considered when designing sealing covers. As an important part of the gearbox, the sealing cover has an important impact on the performance, reliability and safety of the car. Therefore, when designing and manufacturing the sealing cover, various factors need to be fully considered to ensure that it has good functions and performance.

[0003] In the prior art, after the gearbox cover is formed, the upper mold of some processing molds moves upward after the stamping is completed, and the cover is attached to the lower mold, which is difficult to remove and inconvenient for subsequent stamping, reducing the continuity of the cover forming.
