Abstract

The invention relates to the field of rail transit, in particular to a rail transit composite material end wall molding tool, which includes a bottom mold, a guide structure and a movable slider group, the bottom mold has a female mold surface, and the movable slider group encloses a cavity to form a cavity. The cavity is for workers to enter and exit the cavity. The guide structure is fixed on the bottom mold. The movable slider group can slide along the guide structure. The movable slider group has a movable surface. When the movable surface and the movable surface are offset, the movable slider group and The bottom mold encloses and forms a molding groove for laying the prepreg, and the movable surface is arranged on the side close to the cavity. The setting of the cavity in the present invention is convenient for laying prepreg on the inside of the mold manually, and the operation is convenient, and the internal demoulding can be achieved through the setting of the movable slider group and the guiding group, and the demoulding stroke is small, which effectively reduces the workload of workers , improving the molding efficiency.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit composite material end wall forming tooling. Background technique [0002] The existing rail transit vehicle body mainly adopts the metal structure car body, but due to the limitation of the quality, performance and cost of the metal structure car body, in order to meet the growing new demand of rail transit, the rail transit lightweight building is gradually developed Become a new trend of rail transit. The new composite car body is divided into multi-section car bodies for winding and laying intermediate unit modules, end walls and other components, but there is no molding mold corresponding to the composite material car body. Therefore, how to provide a rail transit composite material end wall molding Tooling to adapt to the production of composite material end walls is a technical problem that those skilled in the art need to solve at present. In view of...
