The output end of the first hydraulic push rod 124 is fixedly connected to a push plate 125. After the foaming agent is sprayed on all the foaming molds 2, the top pressing plate 3 moves above the foaming molds 2, and the first hydraulic push rod 124 is started to drive the push plate 125 to press down to extrude the top pressing plate 3, so that each mold cavity is sealed by the upper mold bottom plate 201 and the top pressing plate 3, and the shaping is completed after a certain period of time.

[0024] As Figure 6 and Figure 7 shown, the foaming mold 2 further includes a sliding wheel 204 and a belt connecting block 205.

The sliding pin 212 of one mold assembly 21 is pushed out, and the locking block 213 is pushed into the locking hole 215. After the clamping block 217 is lifted, the locking block 213 is pushed to the bottom. Then, the clamping block 217 is pulled down to make the clamping block 217 be clamped outside the locking block 213 to lock the locking block 213. The two mold assemblies 21 can be connected together. In this way, the cavity size can be freely changed to meet diversified production. Rotating connection seats 211 are fixedly connected to both ends of the mold assembly 21. The two mold assemblies 21 can rotate relative to each other through the rotating connection seats 211.

Electrify the heating wire inside the mold bottom plate. The longitudinal moving component drives the transverse moving component to move above the foaming mold. The transverse moving component drives the mixing component and the strip-shaped nozzle to move from one end of the foaming mold to the other end. Meanwhile, after being mixed by the mixing component, the foaming agent is sprayed out onto the surface of the foaming mold through the strip-shaped nozzle, and then the longitudinal moving component drives the transverse moving component to rise. S6. Repeat step S5 multiple times to complete the spraying operation of the foaming agent in multiple foaming molds. S7. Start the motor to drive the top layer driving pulley to rotate, and pull the top layer pressing plate to move above the foaming mold and then stop.
