[0002] The production of car seat foam is a complex physical and chemical process, mainly using polyurethane foam materials. The foaming process can be divided into low-pressure foaming and high-pressure foaming, which differ in mixing methods and equipment investment. During the foaming process, the polyurethane material undergoes foaming reaction and gel reaction in the mold to form a mesh-like porous closed-cell foam;

[0003] At present, during the foaming operation of automobile seats, the products need to be quickly moved to the cooling room for cooling and fixing after demoulding. This will undoubtedly waste a lot of time during the transfer, and the work is difficult and not conducive to stable production operation.

[0012] Furthermore, an elastic ball is provided on the outer side of the sealing gasket to engage with a positioning groove on the inner side of the inner mold core to fill the gap and form a seal.

[0013] Furthermore, the lower end of the sealing gasket is an inwardly bent inclined plate structure for automatically aligning the sealing gasket with the open groove.

[0014] The utility model has the following beneficial effects:

[0015] When the upper mold and the lower mold are combined, the utility model can automatically insert the sealing gasket into the inside of the open groove to form a seal, and then after the foaming operation, cold air can be directly poured into the air guide pipe to cover the inner mold core to achieve the effect of cooling and curing.
