Problems solved by technology
However, the generalization rate of the integrated aluminum alloy cylinder head casting mold water cooling circulation system is very low, and one product can only meet the needs of one model
At the same time, the water-cooling circulation system of the aluminum alloy cylinder head casting mold that is integrally formed has high requirements for production equipment and tooling due to its large shape, and the manufacturing efficiency is low, and the economic benefits are not good.

Embodiment Construction
[0023] The present invention will be further described below in conjunction with accompanying drawing.
[0024] Such as figure 2 and image 3 As shown, a water-cooling circulation system for aluminum alloy cylinder head casting molds includes a large circulation and a small circulation. Composition of pump valves. Small circulation mainly includes circulating water cooling device, casting water area and related pipelines and pump valves. The pure water making and replenishing device mainly includes a water tank 2, a filter 3, a backwashing device 4, a reverse osmosis device 5, pipelines, and water valves. The circulating water cooling device mainly includes primary heat exchanger 9, secondary heat exchanger 8, chilled water inlet pipe 18, circulating water inlet pipe 19, water inlet pipe 20, circulating water outlet pipe 21, chilled water outlet pipe 22 and water outlet pipe 23 etc. The casting water area mainly includes casting molds 12 and return water tanks 13 .

The invention discloses a water-cooling circulation system for an aluminum alloy cylinder cover casting mold. A water tank is connected with a filter, the filter is connected with a backwashing device, the backwashing device is connected with a reverse osmosis device, and the reverse osmosis device is connected with a circulating water tank; the circulating water tank is connected with the castingmold through a circulating booster pump, the casting mold is connected with a water return tank, the water return tank is connected with a water return pump which is connected with a buffer water tank, and water in the water return tank is pressed into the buffer water tank through the water return pump; the buffer water tank is connected with the water return booster pump, and the water return booster pump is connected with a primary heat exchanger through a water inlet pipe; and the primary heat exchanger is connected with a seondary heat exchanger which is connected with the circulating water tank through a water outlet pipe. Continuous and effective cooling can be provided for the aluminum alloy cylinder cover casting mold, sewage and treatment of the sewage are avoided, and the demand for pure water supplementing amount is small.
Description
technical field [0001] The invention belongs to the technical field of engine cylinder head casting, and in particular relates to a water cooling circulation system for an aluminum alloy cylinder head casting mold. Background technique [0002] The water-cooling circulation system of the existing aluminum alloy cylinder head casting mold adopts an integrated molding scheme, and the mold is manufactured at one time. Such as figure 1 As shown, in the existing casting mold water cooling circulation system, the tap water 1 flows into the soft water tank 15 for softening, and then the softened industrial circulating water flows into the industrial circulating water pool 16 . Then the industrial circulating water in the industrial circulating water pool 16 is pressed into the casting mold 12 to cool the mold, and the generated waste water is discharged to the waste water pool 17 of the factory for sewage treatment. However, the generalization rate of the integrated aluminum allo...
