The profiling upper die 6 is located directly above the profiling lower die 4. The profiling upper die 6 is fixedly connected to the lifting device 7 through the connecting clamp 8. A right-angle groove 41 with an upward opening is provided on the upper end surface of the profiling lower die 4. The lower end of the profiling upper die 6 has a conical head 61 with a right-angle cross-section that can cooperate with the right-angle groove 41, and the tip of the conical head 61 is set to a round head structure.

[0023] In the embodiment of the present invention, the lifting device 7 can be connected to a control switch for controlling the start and stop of the lifting device 7, and Figure 3 Only part of the profiling device 2 is shown, and the fixed platform 3 and the lifting device 7 can be extended to both sides, and multiple profiling lower molds 4 and profiling upper molds 6 can be installed for batch production, and the lifting device 7 can be connected to the fixed platform 3 through devices such as lifting cylinders to form an integrated mechanical equipment.
