Problems solved by technology

[0008] Using water as a heat removal fluid is more efficient than using air, but using a water cooling system necessarily creates some disadvantages
[0009] The first disadvantage is the thermal shock generated by the fluid circulation in suitable channels and suitable grooves usually provided in the body of the mould.
[0010] In the case of too large a thermal head difference between the water and the internal temperature of the mould, there is a risk that cracks will form in the mould, which irreparably damage the mould.
[0011] In water systems formed by parts separate from the mould, problems may arise with the sealing in the areas connecting these parts, with the risk of water leaking outside and inside the mould, with consequences affecting the correct operation of the mould.

Embodiment Construction

[0030] Referring to the accompanying drawings, a cooling system according to the invention for a molding plant, in particular for a casting mold, is indicated generally at 10 .

[0031] Such a cooling system 10 includes:

[0032] - a water treatment plant 11 arranged on the water supply line,

[0033] - a compressed air generating device 12 associated with the air supply line,

[0034] - a device 13 for pressurizing the treated water,

[0035] - Means 14 for mixing air with treated water and controlling the injection of atomized water under pressure towards the cooling circuit 16 of the molding device 15 .

[0036] Such as figure 2 The water treatment plant 11 shown in schematic form in FIG. 2 includes a reverse osmosis or demineralization type water treatment unit 17 to which water is supplied through a water supply main 18 .

[0037] The demineralized water leaving from the water treatment unit 17 enters the tank 20 through the pipe 19, while the subsequent device 22 fo...

Abstract

A cooling system (10) for molding equipment, in particular for casting moulds, the cooling system (10) comprising: water treatment equipment (11); compressed air generation equipment (12); means (13) for pressurizing the water; means (14) for mixing air with the treated water and for controlling the injection of atomized water under pressure towards the cooling circuit (16) of the molding apparatus.

Description

technical field [0001] The invention relates to a cooling system for molding equipment, in particular for casting moulds. [0002] The invention also relates to a device for mixing air with treated water and for controlling the spray of atomized water under pressure. [0003] In particular, such a system is applied on molds for the production of light alloy castings, permanent mold castings, low-pressure die-casting castings or high-pressure die-casting castings, but it is understood that it can be applied generally on molding equipment. Background technique [0004] Today, installations for mold casting of metal alloys are provided with a cooling circuit comprising coils arranged in areas of the plant where an efficient and rapid temperature reduction is required during solidification of the casting. [0005] In most cases, the fluid circulating in such cooling circuits is compressed air, which is blown into the coils and adapted to remove a predetermined amount of heat, w...
