After the raw materials are injected, the upper electromagnet 902 and the lower electromagnet 903 repel each other, so that the upper mold seat 8 moves downward and is sealed with the lower mold seat 5, so that the raw materials are foamed and formed between the lower mold seat 5 and the upper mold seat 8, avoiding the displacement caused by the movement of the lower mold seat 5 and the upper mold seat 8 during foaming, thereby damaging the foamed seat.

[0029] Embodiment 2:

[0041] Embodiment six:

[0042] See also Figure 1-4 The utility model provides a technical solution based on the first embodiment: an angle locking assembly 13 is provided on the base 1, a positioning seat 1304 is symmetrically provided inside the base 1, a moving rod 1303 is slidably connected to the top of the positioning seat 1304, a friction disc 1302 is fixedly connected to the top of the moving rod 1303, an annular electromagnet 1301 is fixedly installed on the upper surface of the base 1, and a third spring 1305 is fixedly connected between the annular electromagnet 1301 and the base 1. The upper surface of the friction disc 1302 is set as a friction surface, and an anti-skid pad with the same size as the friction disc 1302 is fixedly connected to the bottom of the rotating table 4.

[0043] Analysis of the above content: When the rotating table 4 needs to rotate, the annular electromagnet 1301 is energized, and the annular electromagnet 1301 generates magnetic force to attract the friction disc 1302, so that the friction disc 1302 squeezes the third spring 1305 and moves downward, so that the friction disc 1302 is separated from the rotating table 4, and the reduction motor 2 can drive the rotating table 4 to rotate.
