Then, the vacuum unit (38) is used to extract the gas in the first working space and the second working space that have been isolated from the atmosphere, so that the space becomes a vacuum, and at the same time, the first heating The unit (36) and the second heating unit (37) provide heat to the mold, while the first vertical mold clamping mechanism (30) provides the mold with clamping force, so that the foamed polymer articles in the mold are subjected to heat It is given a specific shape by the action of pressure. Among them, in order to achieve a better vacuum degree, the above-mentioned air extraction operation can be completed before the mold is completely closed to avoid air remaining in the mold after the mold is closed. Therefore, in a vacuum environment, the heat energy supplied by each heating unit can be prevented from being dissipated into the gas, so as to reduce the waste of heat energy.

After the foamed polymer molded article in the mold has been repeatedly hot-pressed and shaped by the hot zone workstations of the two stations, it will then enter the cold zone workstations of the two stations for the cooling and shaping procedure, but for the cooling shaping and subsequent cleaning procedures , Which is not the technical feature of this creation, and is already disclosed by the prior art, so no further explanation will be given.
