Abstract

The application relates to a mold cooling system and its control method, control device and computer equipment. The mold cooling system includes: movable side cooling device; fixed side cooling device; water tank; and intermittent cooling device, the air inlet is used to connect the cooling air source, the first air outlet is connected to the air inlet of the movable side cooling device, The second air outlet is connected to the air inlet of the cooling device on the fixed side, the first water inlet is used to connect the water inlet pipe of the cooling device on the movable side, the second water inlet is used to connect the water inlet pipe of the cooling device on the fixed side, and the first water outlet is connected to the movable side The second water inlet of the side cooling device, the second water outlet is connected to the second water inlet of the fixed side cooling device; it is used to select the preset intermittent cooling mode according to the product temperature to locally cool the product. The mold cooling system can realize controllable and natural "sequential solidification" process measures by controlling the start and stop of the intermittent cooling device, water supply and ventilation time, realize natural feeding and solve the problem of shrinkage cavity inside the product.

Description

technical field [0001] The present application relates to the technical field of aluminum alloy casting, in particular to a mold cooling system and its control method, control device and computer equipment. Background technique [0002] During the casting process of aluminum alloy, the products are cut off, the shape of the internal sand holes is irregular, and the holes with rough surface are caused by the shrinkage cavity caused by the insufficient internal compensation of the product during the casting cooling process. The reason for the phenomenon of shrinkage cavity in the product is due to the inevitable phase transition and shrinkage when the liquid phase is transformed into a solid phase after the metal solution is filled. Since the solidification characteristic of high pressure casting is cooling from the outside to the inside, when the product wall thickness is large , the problem of shrinkage cavity will inevitably occur inside. If it cannot be solved, the intern...
