PURPOSE: To make it possible to mount a lifting apparatus to a mold or to dismount the apparatus from the mold, by engaging cylinders that are fitted to rotatable arms attached to the lifting apparatus with window sections in projections and notches.

CONSTITUTION: The main body 12 of a lifting apparatus 4 can be moved along a frame 3 by a motor 13 that can be rotated forward or backward, and the undersurface of a support 16 thereof has pairs of cylinders 17, 18 that are secured to and extended through a cover body 6 for covering the upper opening section of a mold 5. Arms 22 attached to the lower ends of shafts 19 and projected from the lower ends of the cylinders 17 can be rotated within a specified range by the rotation of the motor 13. Each cylinder 18 is formed with a window section 18a into which the arm 22 will be admitted when the arm 22 is rotated. A flange section 23 formed around the opening of the mold 5 has projections 24 at positions opposite to the cylinders 18, and each projections 24 is formed with a notch 24a. The position of the notch 24a is situated such that when the projection 24 is fitted into the cylinder 18, the notch 24a coincides with the window section 18a in the cylinder 18. Thus the lifting apparatus can be easily mounted to the mold or dismounted therefrom.
