This utility model relates to the field of automotive
stamping die
manufacturing technology, and in particular to a
compression molding and
punching die for lightweight composite LWRT parts for automobiles. It includes a lower die, an upper die, and an
electrical control system. The lower die includes a lower die base
assembly, a lower die core
assembly, a lower die pressure frame
assembly, and a lower die forming limiting mechanism. The upper die includes an upper die base assembly, an upper die core assembly, a floating die assembly, and an upper die pressure frame assembly, each assembly mounted on its corresponding die base. The
electrical control system includes
electrical control components for the lower die and upper die, respectively electrically connected to the lower die and upper die.
Integrated production is achieved by combining the lower die, upper die, and electrical
control system. The limiting block, in conjunction with a displacement sensor, enables time-sharing of forming and
punching actions. The electrical
control system communicates with the press equipment via a 16-pin socket, and, combined with the coordinated action of an induction plate,
solenoid valve, and cylinder, achieves full-process
automation, improving production efficiency and quality stability. This solves the problems of low forming and
punching quality stability and difficulty in achieving high-efficiency production requirements associated with traditional processes.
