形装置。[Scope of Claim for Utility Model Registration] 1. A synthetic resin molding device that thermally softens a synthetic resin sheet clamped on a clamp stage and then molds it into a desired shape using a molding die, the molding device comprising a heater and a lower surface. includes a box-shaped vacuum chamber with an open opening, and when the synthetic resin sheet is softened, the vacuum chamber is airtightly placed on the clamp stage, and the heater softens the synthetic resin sheet while reducing the pressure inside the vacuum chamber. 1. A synthetic resin molding apparatus characterized in that a softened synthetic resin sheet is maintained horizontally. 2 The above heater is installed inside the vacuum chamber,
2. The molding apparatus according to claim 1, wherein a detecting means is disposed on the inner surface of the chamber near the opening, and the detecting means detects the degree of swelling of the softened synthetic resin sheet.
