PROBLEM TO BE SOLVED: To enable a stable degassing by constantly providing a certain gap between upper and lower molds and an optimum degassing by appropriately adjusting the magnitude of the gap. SOLUTION: An opening control device 32 comprises an oscillating lever 34 disposed on an upper mold 12 so as to be oscillatingly displaced by an operating means 36, an adjusting member 40 disposed in such a manner as to be freely adjusted back and forth in a state in which it protrudes from an oscillating tip portion of the oscillating lever 34, and a control member 38 disposed at a side portion at an open end of the lower mold 14. When gas is discharged from a cavity, the upper mold 12 is opened to a position where the adjusting member 40 is brought into abutment with the control member 38 in a state in which an engagement between a clamp lever 22 and an engagement member 26 is released, whereby a further opening of the upper mold 12 is restricted, and a gap S between the upper 12 and lower 14 molds is controlled so as to be constant at all times by adjusting the gap between the control member 38 and the adjusting member 40. |
