るとともにエアホース６７の移動抵抗を減じている。When the trolley floating valve of the air switching valve 66 is opened and compressed air is sent to the dolly 50 for mold replacement, the air pad 52 swells upside down like an arm and the air ejected from the hole in the lower surface causes the air pad 52 to swell. The dolly 50 floats above the floor away from the floor. The trolley 50 is moved to the front of the target molding machine 75 by hand and the traveling wheels 57a and 57b of the trolley body 51. That is, when the vertical or horizontal traveling valve of the air switching valve 66 is opened, the traveling wheel 57 is moved by the air cylinder 60.
a or the traveling wheel 57b descends and comes into contact with the floor, and at the same time, the air motor 61 rotates and the carriage 50 travels vertically or horizontally. The direction is changed by manually operating the handle 56 to rotate the carriage 50. When you reach the front of the molding machine 75,
First, the V-shaped convex block 54 provided on the trolley body 51 side is fitted into the V-shaped concave block 70 provided on the molding machine 75 side, and the flat block 55 on the trolley body 51 side is fitted.
Is brought into contact with the flat block 71 on the molding machine 75 side, and the air in the air pad 52 is released while maintaining this state. The dolly 50 descends and abuts the leg pads 53 on the lower surface of the dolly body 51 on the floor pad 72 on the floor side to stop. The height of the floor pad 72 is equal to that of the drive conveyor 63 of the mold moving device 62 on the side of the carriage 50.
The height is adjusted in advance so that the height of the drive conveyor 73 on the side of the molding machine 75 is the same. Next, the mold 74 is moved in and out of the molding machine 75 using the mold moving device 62 provided on the carriage main body 51. The drive conveyor 63 is driven by the air motor 64. The air hose 67 is fed from a reel (not shown) provided at the base. A hose protection roller 69 is provided at a place where the carriage 50 bends so as to prevent the hose protection roller 69 from hitting peripheral devices and reduce movement resistance of the air hose 67.

が十分に行われる。[0008] A conventional truck running on a rail needs a rail for the truck to travel, and when a plurality of molding machines are supported, these molding machines must be arranged in the same direction. Therefore, it is difficult to deal with a plurality of molding machines that are arbitrarily arranged. In particular, although it cannot be applied to a molding machine that is arranged obliquely or at a right angle, the mold replacement carriage is an air floating type using the air pad 52, and the mold replacement carriage 50 is floated by compressed air. At the same time, two sets of traveling wheels 57a and 57b provided orthogonally to the lower surface of the carriage 50 are driven by the air motor 61 to move in two orthogonal directions. In addition, a set of V-shaped blocks provided at intervals in the horizontal direction with respect to the molding machine 75 are fitted in a concave-convex shape, and a set of flat blocks are in contact with each other at two points. In the vertical direction, four flat leg pads 53 and a floor pad 72 fixed to the floor are brought into contact with each other for positioning. Further, a hose protection roller 69 is provided to protect the air hose 67 at a position where the carriage 50 changes its moving direction. Mold 7 using this mold replacement cart
4 is exchanged, the compressed air is supplied to the air pad 52 by the air hose 67 to float the truck 50 from the floor surface, and two sets of traveling wheels 57 on the lower surface of the truck body 51 of the human body.
The carriage 50 is moved to the front of the target molding machine 75 using a and 57b, and the V-shaped convex block 54 provided on the carriage 50 side is changed to the V-shaped concave block 70 provided on the molding machine 75 side. After the insertion, the flat blocks 55 and 71 on the side of the carriage 50 and the molding machine 75 are brought into contact with each other, and when the air of the air pad 52 is removed while maintaining this state, the carriage 50 descends and is fixed to the lower surface of the carriage main body 51. Since the leg pad 53 provided is placed on the floor pad 72 fixed on the floor side and stopped, the die moving device 62 provided on the carriage 50 is used to form the die 74. Put in and out at 75. In this way, the molds 74 can be moved and replaced regardless of the positions and directions of the molding machines 75. Further, since rails and guide wires are unnecessary and only compressed air is used as an energy source, the structure of the carriage 50 is simplified and the cost is reduced. In addition, the hose protection roller 69 sufficiently protects the air hose 67.
