PURPOSE:To prevent parallel movement of molds during ascending of the lower mold or mis-alignment, etc., at the time of mold clamping by freely movably disposing the lower mold mounted with a slider which is moved by plural pieces of high-precision guide devices to the bottom surface part of a molding chamber fixed with the upper mold in the upper part. CONSTITUTION:The molding chamber 14 consisting of a housing 13 is fixed to the upper part of posts 12 erected on a base plate 11 and the upper mold 15 is fixed via a plate 16 to the ceiling surface 14a in the upper part of the chamber 14. The lower mold 17 interlocked to a driving means 18 is positioned oppositely to the upper mold 15 and is disposed to the base 14b side in the lower part in such a manner that said mold can be freely lifted in the vertical direction. The driving means 18 is provided with a high-rigidity bracket 19 which is fixed to the bottom surface part of the housing 13 and has the strength to withstand the mold clamping force without causing deformation, a hydraulic cylinder 20 which is built to the under side thereof, a swivel joint 22 which is mounted to the top end of the cylinder 20, and plural pieces of the high-precision guide devices 24 which lift and guide the slider 23 built in the bracket 19 via the joint 22 in the vertical direction. The lower mold 17 is built and fixed to the top end part 26a of a press shaft 26 mounted to the slider 23.
