[0009] In order to facilitate the realization of the above production functions, the following process is provided: After the foaming process is completed, the lower mold needs to be cleaned, and the upper and lower molds are closed. First, the cold water heater heats the water. After heating, the hot water transfers the heat to the lower mold through the temperature-controlled water pipe. The lower mold and the wax scale remaining in the mold are heated. After heating for 5 minutes, the water in the temperature-controlled water pipe is drained away. The dry ice cleaning machine guides the dry ice into the nozzle through the conduit. The nozzle guides the dry ice into the lower mold and quickly cools the wax scale in the lower mold to crack the wax scale. Then open the upper mold and clean up the cracked wax scale.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The invention discloses an automatic foaming production line for automobile seats and a process thereof, wherein the wax scale in the lower mold is heated and then rapidly cooled by dry ice. Such rapid thermal expansion and contraction can accelerate the cracking of the wax scale and the process is completed automatically without manual operation. BRIEF DESCRIPTION OF THE DRAWINGS
