Description of the Related Art A sliding surface of a movable die plate in a mold clamping device of a die casting machine is used for dropping droplets of a water-soluble release agent and dropping of solidified pieces of molten metal such as burrs and flashes of a die-cast product. The lubricating oil mixes into a poorly cleaned state. For this reason, a wiper is provided on the sliding surface to prevent the mixed material from entering the sliding surface. In a large-sized machine, a cover that covers a sliding surface is configured to be extendable and contractable, and a wiper is provided in an extendable portion of the cover.

A mold (not shown) between the die 1 and the moving die plate 1 is opened, and a water-soluble mold release agent is sprayed on the mold opening surface, and the molten metal coagulated pieces such as burrs and flashes of the die-cast product are dissolved in the water-soluble mold release agent. At the same time, even if it falls on the belt 10, the fallen molten metal coagulated pieces and the water-soluble release agent are sent to the guide roller box 7 side with the movement of the belt 10 as the moving die plate 1 advances and retreats. The gutter 16 which is removed by the wiper 15 located at the upper end of the member 13 forming part of the sliding plate 3 and falls down to the lower side of the stepped slide plate 3 and then the gutter 16 adjacent to the lower side is removed. It flows out to a waste box (not shown). The width of the belt 10 is larger by a small dimension w on both sides than the width of the sliding surface 3a, and since the wiper 11 fixed to the upper part of the sliding plate 3 is in sliding contact with the back surface of the belt 10, the sliding surface 3a There is no infiltration of the molten metal coagulation pieces and the water-soluble release agent into the sliding surface 3a, and there is no mixing with the lubricating oil on the sliding surface 3a. Further, the molten metal coagulated pieces and the water-soluble release agent that have fallen onto the guide roller box 7 having the fully closed structure also flow out to the waste box (not shown) through the gutter 16.
