Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle mesh bottom shell technology, and relates to a core-pulling and demolding mechanism for the bottom shell mold of electric four-wheeled vehicle mesh. Background Technology

[0002] An electric four-wheeled vehicle is a four-wheeled vehicle with one front steering wheel on each side and one rear drive wheel on each side. Both front wheels have steering capabilities, and at least the rear drive wheels have driving capabilities. Currently, most electric four-wheeled vehicles on the market use a one-piece frame structure. The electric four-wheeled vehicle's underbody is an important component of the vehicle chassis, primarily responsible for protecting the battery pack, optimizing space utilization, and improving safety. The electric four-wheeled vehicle's underbody typically consists of components such as the battery pack underbody, water-cooling plate, and insulation plate, and is directly installed below the battery pack to fix the battery cells and protect the power battery pack from external impacts. Additionally, some models integrate a water-cooling system into the underbody, using circulating liquid for heat dissipation.

[0003] Traditional mesh bottom shell structures are directly processed by injection molding. During injection molding, traditional molds are ejected directly by ejector pins, resulting in the modules being molded as a single piece. This means that the side structures of the modules can only be molded as a single piece and cannot be adjusted according to different mesh bottom shell side structures. Improvements are needed, and the side fixing structures of the mesh bottom shell also need to be molded as a single piece. Summary of the Invention

[0004] The purpose of this utility model is to provide a core-pulling and demolding mechanism for the bottom shell mold of the grille of an electric four-wheeled vehicle, so as to solve the problems mentioned in the background art.
