式の金型反転装置を提供することである。In the mold reversing device described in the above publication, the piston rod of the hydraulic cylinder is horizontal when the piston rod of the hydraulic cylinder is extended to switch the mold supporting plate to the vertical posture. Since the lower side of the support shaft passes through the support shaft in an intersecting manner, the hydraulic cylinder is positioned sufficiently low with respect to the horizontal support shaft, and the height of protrusion of the bracket downward from the mold support plate is high. Needs to be large enough. As a result, the total height of the mold reversing device becomes large, and the pit dug down from the floor for disposing the mold reversing device becomes deep, which is disadvantageous in terms of equipment cost. A base frame is required to connect the ends of the cylinder body of the hydraulic cylinder to both ends of the, and the large number of large members such as this base frame and bracket increase the size and weight of the die reversing device,
There are problems such as being disadvantageous in manufacturing cost. An object of the present invention is to provide a hydraulic cylinder type mold reversing device that can be reduced in size and weight by reducing the overall height, and can reduce manufacturing costs and equipment costs.
