A casting apparatus includes an upper frame, a lower frame, an opening/closing mechanism, a first main link member, a first sub-link member, a drive unit, a base frame and a retracting mechanism. The first main link member is provided with a first rotating shaft at a central part thereof. The first sub-link member is disposed in parallel with the first main link member. The first sub-link member is provided with a first bearing at a central part thereof. The drive unit is connected to the first rotating shaft and causes the first main link member to rotate around the first rotating shaft. The base frame includes a second rotating shaft. The second rotating shaft rotatably supports the first sub-link member via the first bearing with the first bearing placed thereon. The retracting mechanism causes the second rotating shaft to retract.

Casting device

A casting apparatus includes a first drive unit closing or opening an upper mold and a lower mold, a second drive unit tilting the closed upper mold and lower mold, an optical sensor and a control unit. When the optical sensor detects an object during a casting period after molten metal is supplied to the upper mold and the lower mold tilted by the second drive unit until the molten metal is cooled, the control unit does not shut off power supplies to the first drive unit and the second drive unit, causes the first drive unit to continue mold closing and causes the second drive unit to hold the tilting position.

Casting device and emergency stop method

A casting apparatus includes an upper frame to which an upper mold is attached, a lower frame to which a lower mold is attached, an opening/closing mechanism, a first main link member whose central portion is provided with a rotating shaft, a first auxiliary link member whose central portion is provided with a rotating shaft, and a drive unit. The upper frame, the lower frame, the first main link member, and the first auxiliary link member constitute a first parallel link mechanism.

Casting device and mold replacement method for casting device

A casting apparatus of a casting equipment includes an upper frame to which an upper mold is attached, a lower frame to which a lower mold is attached, a mold closing mechanism, a pair of main link members each of which has a central portion provided with a rotating shaft, a pair of auxiliary link members each of which has a central portion provided with a rotating shaft, and a drive means. The upper frame, the lower frame, the main link member, and the auxiliary link member constitute a parallel link mechanism.

Casting facility

Casting machine

A casting machine is provided for producing an as-cast product by using horizontally split type metal molds, which are closed and held horizontally to define a cavity, and by pouring molten metal from a holding furnace into the cavity. The casting machine includes a metal drag held horizontally at a fixed position; a plurality of upwardly-facing cylinders disposed around the metal drag and mounted on a floor or a base, each cylinder having a cylinder rod that extends and retracts; and a cope die base mounted for vertical movement on the distal ends of the cylinder rods of the upwardly-facing cylinders for horizontally holding a metal cope at a position above the metal drag so that the metal cope is mated with the metal drag to define the cavity when the cope die base is lowered by the upwardly-facing cylinders.
