Description
Technical field
The utility model relates to a kind of Casting Equipment, particularly relates to a kind of accurate casting mold apparatus improving casting quality.
Background technology
Casting technique pours in mold by the metal liquid of molten condition, after supercooling, cleaning process, obtain the process of foundry goods, and it is the technique on foundry industry basis the most.
But existing Casting Equipment is all adopt the mode of artificial observation or estimation to carry out casting metal liquid usually, and cause metal liquid dosage inaccurate, cause casting quality poor, ratio of briquetting is low, and precision is low.And for complex-shaped foundry goods, then need to carry out shaking just can complete, equipment investment cost is high, and production cost is high, ratio of briquetting and quality are also difficult to ensure.
Utility model content
In order to solve the problem, the utility model provides a kind of accurate casting mold apparatus, and its structure is simple, and easy to use, cost is low, and reduce equipment investment cost and use cost, ratio of briquetting is high, and casting quality is good.
To achieve these goals, the technical solution of the utility model: accurate casting mold apparatus, is characterized in that, comprise foundry sand room, foundry sand indoor are provided with mold shell, and the mold sprue gate of mold shell is provided with quantitative liquid feeding device, and mold sprue gate is connected with quantitative liquid feeding device is airtight;
Lower end, foundry sand room is provided with vacuum chamber, is isolated between vacuum chamber and foundry sand room by separation net, is arranged with a circle high-temperature resistant seal ring outside foundry sand room and vacuum chamber junction;
Vacuum chamber is by vacuum pump evacuation, and vacuum chamber is connected by vacuum tube with vavuum pump, and vacuum tube porch is provided with screen pack;
Sewage draining exit is provided with bottom vacuum chamber.
In some embodiments, quantitative liquid feeding device is controlled by fluid supplier controller.
In some embodiments, vacuum tube is provided with pressure tester.
In some embodiments, described pressure tester is Pressure gauge.
In some embodiments, vavuum pump is controlled by vavuum pump control valve.
The accurate casting mold apparatus that the utility model provides compared with prior art, has the following advantages:
The utility model structure is simple, and easy to use, cost is low.Have employed dosage fluid supplier, make feed flow accurate, avoid waste, improve precision simultaneously, also improve the quality of ratio of briquetting and foundry goods.In addition, adopt the mode that vacuumizes, such that molten metal physical efficiency is whole to be filled in mold shell, reduce the generation of bubble, also eliminate the vibrations equipment of cost intensive simultaneously, and then reduce equipment investment cost and production cost.In addition, also can prevent impurity from entering vavuum pump, prevent vavuum pump from damaging, the impurity of filtering can be got rid of in time in vacuum chamber.
Accompanying drawing explanation
Fig. 1 is the structural representation of the accurate casting mold apparatus of a kind of embodiment of the utility model.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, explanation is described in further detail to the technical solution of the utility model.
Fig. 1 schematically shows the accurate casting mold apparatus provided according to a kind of embodiment of the utility model.
As shown in Figure 1, in this embodiment of the present utility model, accurate casting mold apparatus comprises foundry sand room 1, mold shell 2 is provided with in foundry sand room 1, the mold sprue gate 21 of mold shell 2 is provided with quantitative liquid feeding device 3, mold sprue gate 21 is connected with quantitative liquid feeding device 3 is airtight, and quantitative liquid feeding device 3 is controlled by fluid supplier controller 31.Lower end, foundry sand room 1 is provided with vacuum chamber 4, is isolated between vacuum chamber 4 and foundry sand room by separation net 5, is arranged with a circle high-temperature resistant seal ring 7 outside foundry sand room 1 and vacuum chamber 4 junction.
As shown in the figure, vacuum chamber 4 is vacuumized by vavuum pump 6, and vavuum pump 6 is controlled by vavuum pump control valve 12.Vacuum chamber 4 is connected by vacuum tube 8 with vavuum pump 6, and vacuum tube 8 is provided with pressure tester 11, and preferably, this pressure tester is Pressure gauge.
In addition, vacuum tube 8 porch is provided with screen pack 9; Sewage draining exit 10 is provided with bottom vacuum chamber 4.
The accurate casting mold apparatus that the utility model provides, have employed dosage fluid supplier, makes feed flow accurate, avoids waste, improve precision simultaneously, also improve the quality of ratio of briquetting and foundry goods.In addition, adopt the mode that vacuumizes, such that molten metal physical efficiency is whole to be filled in mold shell, reduce the generation of bubble, also eliminate the vibrations equipment of cost intensive simultaneously, and then reduce equipment investment cost and production cost.In addition, also can prevent impurity from entering vavuum pump, prevent vavuum pump from damaging, the impurity of filtering can be got rid of in time in vacuum chamber.
Below be only the utility model preferred embodiment; it should be pointed out that to those skilled in the art, under the prerequisite not departing from the utility model creation design; can also make some similar distortion and improvement, these also should be considered as within the protection domain of utility model.
