Claim Text:
1. A pressure-controlling foam molding method comprising steps of: a.1. preparing a mold seat, drivable over a pair of parallel first guide rails by a first power member installed therebetween, including a.2. positioning a first mold and a second mold in the first receiver and the second receiver, respectively, b. using the first mold to mold at least one blank; c. moving the first mold plate and the second mold plate in a direction parallel to a pair of second guide rails, which run perpendicular to the first guide rails and are slidably disposed with a body section, said body section powered by a second power member, through the first opening and the second opening, respectively, into an upper opening and a lower opening of a closed pressure-controlling space, respectively, wherein the pair of parallel first guide rails, the first power member, the pair of second guide rails, and the second power member are all installed on a base seat; and d. keeping a pressure in the pressure-controlling space at a predetermined transfer pressure and under a transfer pressure environment, moving the blank out of the first mold pit of the first mold plate along a moving axis in parallel to gravity direction; and e. with the plane on which the opening of the second mold pit is positioned as a projection face and with the shape and position of the opening of the second mold pit corresponding to the vertical projective shape and position of the blank, moving the blank into the second mold pit of the second mold plate along the moving axis.
