Description

Technical Field

[0001] The present application relates to the technical field of injection molds, and in particular to an injection mold for a stop valve mounting seat. Background Art

[0002] New energy vehicles generally refer to vehicles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures.

[0003] New energy vehicles mainly include pure electric vehicles (BEV), hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), extended-range electric vehicles (REEV) and fuel cell electric vehicles (FCEV); the development of new energy vehicles has many advantages. On the one hand, they help reduce dependence on traditional fossil energy and reduce the risk of energy imports; on the other hand, they can effectively reduce exhaust emissions and alleviate environmental pollution and climate change problems.

[0004] For new energy vehicles powered by pure electricity, in order to ensure the safety of the whole vehicle, ensure energy consumption and cruising range, coordinate the temperature requirements of various components, etc., its thermal management system is particularly important. Among them, the stop valve is a component in the thermal management system of new energy vehicles. The function of the stop valve is mainly to control the flow of refrigerant. By opening and closing the stop valve, the cooling or heating process can be adjusted to ensure that the battery, motor and other components are at a suitable working temperature and improve the performance and safety of new energy vehicles. Usually, in order to ensure the stability of the stop valve installation, the stop valve is installed on the stop valve mounting seat to ensure that the stop valve will not shift or loosen due to vibration, bumps and other factors during the operation of the vehicle. In addition, it can also play a role in sealing and protection, precise positioning, transmission of force, and reduction of local stress concentration.

[0005] In order to facilitate the installation of the stop valve, the stop valve mounting seat needs to be integrally formed with the nut during molding. However, for nuts located lower, the space on the molding mold is limited, and the copper nut cannot be installed in the conventional mold structure space.

[0006] This application uses: valve seat, stop valve mounting seat, injection mold, nut, installation, etc. as keywords, and no relevant technical solutions are retrieved.

[0007] In summary, it is necessary to provide a new technical solution to solve the above technical problems. Utility Model Content
