Abstract: A casting apparatus according to the present disclosure includes an upper frame, a lower frame, a main link member, a sub-link member and a lifting/lowering mechanism. The upper mold is attached to the upper frame. The lower frame is disposed in parallel with the upper frame. The lower mold is attached to the lower frame. A top end part of the main link member is rotatably connected to the upper frame and a bottom end part thereof is rotatably connected to the lower frame. The sub-link member is disposed in parallel with the main link member, the top end part thereof is rotatably connected to the upper frame and the bottom end part thereof is rotatably connected to the lower frame. The lifting/lowering mechanism causes the sub-link member to lift or lower with respect to the main link member.

Abstract: The foundry sand binder supply apparatus of the present invention comprises a hopper for storing a binder therein, a binder transfer device for transferring the binder, a binder measuring and discharging device disposed beneath a distal end of the binder transfer device, and a binder supply amount control device. The binder measuring and discharging device comprises a measuring container for receiving the binder therein, a load cell for measuring the weight of the binder inside the measuring container, and a discharge device for discharging the binder from the measuring container. The binder supply amount control device is operable to control the discharge device to discharge the binder from the measuring container by a predetermined amount less than the whole amount of the binder inside the measuring container, and control the binder transfer device to supply the binder into the measuring container by the predetermined amount of the discharged binder.
