The invention relates to a mold cooling system, a control method and device thereof and computer equipment. The mold cooling system includes a movable side cooling device, a fixed side cooling device,a water tank and an intermittent cooling device; an air inlet is used for being connected with a cooling air source, a first air outlet is connected with an air inlet of the movable side cooling device, a second air outlet is connected with an air inlet of the fixed side cooling device, a first water inlet is used for being connected with a water inlet pipe of the movable side cooling device, anda second water inlet is used for being connected with a water inlet pipe of the fixed side cooling device; a first water outlet is connected with a second water inlet of the movable side cooling device, and a second water outlet is connected with a second water inlet of the fixed side cooling device; and the intermittent cooling device is used for selecting a preset intermittent cooling mode to locally cool a product according to the product temperature. According to the mold cooling system, controllable natural 'sequential solidification' process measures can be achieved by controlling the start-stop time, the water supply time and the ventilation time of the intermittent cooling device, natural feeding is achieved, and the problem of shrinkage cavities in the product is solved.
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...
