Abstract
The utility model discloses a device for improving the dimensional accuracy of thick and large wax moulds undergoing precision investment casting, comprising a metal mould; a U-shaped water tank is arranged at the upper and lower parts of the metal mould; a water inlet and a water outlet are arranged on the upper surface of the U-shaped water tank; the water inlet and the water outlet are respectively connected with a water chiller via cooling water pipes; the water chiller is filled with cooling water; and a water pump is arranged at the upper end of the water chiller. In the utility model, water cooling is added in the mould, the cooling water circulates to take away the heat in the mould after wax pressing and then the wax moulds can be rapidly cooled and shaped in the mould, so that stable wax mould dimensions can be obtained.
Description
Technical field
The utility model relates generally to precision-investment casting molding field, relates in particular to a kind of device that improves thick big the wax-pattern dimensional accuracy of investment pattern precision casting.
Background technology
When the precision-investment casting wax-pattern was made, even each position of thick big wax spare of some wall unevennesses can not be solidified simultaneously, and influenced by product structure can to cause local contraction to be obstructed, and wax-pattern very easily produces distortion, thereby causes casting dimension overproof.Traditional method is to utilize the ice water system on the wax injector that mould is cooled off, but because mould is thick big, and cooling velocity is slower, and this patent is employed in the method that increases water-cooled in the mould, reaches the effect of quick cold wax-pattern, can obtain the wax spare of dimensionally stable with this.
The utility model content
The purpose of the utility model is exactly in order to remedy the defective of prior art, a kind of device that improves thick big the wax-pattern dimensional accuracy of investment pattern precision casting to be provided.
The utility model adopts following technical scheme:
Improve the device of smart thick big the wax-pattern dimensional accuracy of fusible pattern; Include metal die; It is characterized in that: the last mo(u)ld bottom half of described metal die is provided with " U " type tank, and the upper surface of described " U " type tank is provided with water inlet and delivery port, and described water inlet is connected with the frozen water machine with cooling water pipe respectively with delivery port; Fill it up with cooling water in the described frozen water machine, the upper end of frozen water machine is equipped with water pump.
The device of smart thick big the wax-pattern dimensional accuracy of described raising fusible pattern, it is characterized in that: described metal die material can be wrought aluminium or cast aluminium.
The device of smart thick big the wax-pattern dimensional accuracy of described raising fusible pattern, it is characterized in that: said cooling water is demineralized water or distilled water.
The beneficial effect of the utility model:
The utility model is in mould, to add water-cooled, and the heat in the mould is taken away in the cooling water circulation behind the pressure wax, and wax-pattern can cool off fast in mould, finalize the design, and can obtain highly stable wax-pattern size like this.
Description of drawings:
Fig. 1 is the metal die structural representation.
Fig. 2 is the structural representation of the utility model.
The specific embodiment:
As shown in Figure 1; Improve the device of smart thick big the wax-pattern dimensional accuracy of fusible pattern, include metal die 1, the last mo(u)ld bottom half 2 and 3 of described metal die 1 is provided with " U " type tank 5; The upper surface of described " U " type tank 5 is provided with water inlet 6 and delivery port 7; Described water inlet 6 is connected with frozen water machine 9 with cooling water pipe 8 respectively with delivery port 7, and described frozen water machine is filled it up with cooling water for 9 li, and the upper end of frozen water machine 9 is equipped with water pump 10.
The device of smart thick big the wax-pattern dimensional accuracy of described raising fusible pattern, described metal die material can be wrought aluminium or cast aluminium.
The device of smart thick big the wax-pattern dimensional accuracy of described raising fusible pattern, said cooling water is demineralized water or distilled water.
