When it is lowered, the engagement plates at the tips fit into the engagement grooves of both positioning blocks. Also, the lower side of the side plate located on the fixed board side is fitted with the recess of the stopper. At this time, since both sides of the recess are formed in a V-shape, if the position of the lower side is shifted laterally, the lower side is pushed laterally by the inclined surface of the recess as it descends and reaches the fitting position. You will be guided. The lateral force due to the inclined surface is also transmitted to the bogie, so that the level of the bogie and the lateral positioning are simultaneously performed.

行うことができるなどの利点を有する。Accordingly, the carriage on which the mold is placed is moved to the side of the mold clamping device, the both side plates of the roller unit are placed on the line of the positioning block, and the engaging plate at the tip is located on the engaging groove to reduce the seat height of the carriage. Positioning can be performed reliably by simply lowering the height to the set height, and since the bogie is locked to the molding machine via the roller unit by the engagement plate, the mold is being transferred from the roller unit to the mold clamping device. Even if an external force acts on the trolley, the trolley does not move away from the trolley and the mold will not be in an unstable state, so that there is an advantage that the dies can be changed more safely and more efficiently than before. .
