[0030] In this embodiment, the lower end surfaces of the plurality of fixing rods 11 are in contact with the corresponding convex strips 15, so that the upper end surface of the finished seat cushion body 17 has air holes, thereby increasing the air permeability of the seat cushion.

[0031] As a technical optimization solution of the utility model, the inner wall of the placement groove 3 is fixedly connected with an inner edge, and the lower end surface of the upper mold 4 is provided with a groove matching the inner edge.

[0032] In this embodiment, the groove of the upper mold 4 abuts against the inner edge of the placement groove 3 , so that the upper mold 4 is more stable inside the placement groove 3 .

[0033] As a technical optimization solution of the utility model, a sealing gasket 9 is fixedly connected to the inner wall of the mold cover plate 7 .

[0034] In this embodiment: the sealing performance of the mold cover plate 7 is increased by the sealing gasket 9 .

[0035] The working principle and use process of this utility model:

[0036] During processing, the mold cover plate 7 is closed, and the foaming material is placed in the mold cavity 2. The upper mold 4 is driven downward by the first electric telescopic rod 6 to make the upper mold 4 enter the interior of the placement groove 3, so that the lower end surfaces of the mold core 12 and the fixing rod 11 are respectively in contact with the protrusion 16 and the protrusion 15, and at the same time, the groove of the upper mold 4 is in contact with the inner edge of the placement groove 3, so that the upper mold 4 is more stable in the placement groove 3;

[0037] After the processing is completed, the upper mold 4 is first driven by the first electric telescopic rod 6 to move upward, so that the upper mold 4 drives the mold core 12 and the fixing rod 11 to move upward and detach from the interior of the finished seat cushion body 17, so that the upper end surface of the finished seat cushion body 17 has air holes and notches. The air holes make the finished seat cushion body 17 more breathable, and the notches prevent the finished seat cushion body 17 from compressing the coccyx of the human body, making the seat cushion more comfortable.

[0038] Then, the output end of the second electric telescopic rod 10 is extended to drive the mold cover plate 7 to flip downward, so that the finished seat cushion body 17 can be moved out from the interior of the mold cavity 2. A cavity is opened inside the finished seat cushion body 17 through the cross plate 14 and the two arc-shaped plates 13 to facilitate the installation of support parts and increase the support of the seat cushion. The bottom of the finished seat cushion body 17 is provided with multiple anti-slip strips through the convex strips 15 to increase the friction of the bottom of the seat cushion and prevent the foam seat cushion from deflecting and tilting.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
