AI Technical Summary
The existing mold design for electric vehicle seat bucket covers is complex and bulky, especially when dealing with recessed structures, which requires multiple spring blocks to work together, resulting in wasted mold space and increased costs.
The large spring block structure is adopted, with the front end of the spring block having an inclined guide block and a side guide groove. Combined with the inclined guide groove and side guide groove of the upper mold base, the spring block can achieve stable sliding support, reduce the number of spring blocks, and simplify the mold design.
It simplifies the mold structure, saves internal space in the mold base and injection molding costs, reduces the failure rate, and improves demolding stability.
