Abstract
The utility model relates to a negative-pressure sand box for lost foam casting, which comprises an inner box and an outer box, wherein the inner box is arranged in the outer box; flat strengthening ribs are arranged on the outer sides of the bottom and the middle of the inner box respectively; outward bent angle steel strengthening ribs are arranged at the top of the inner box; outward turned-over edges are arranged at the top of the outer box; slots are formed in four inner side surfaces of the outer box; isolating screen stencils are respectively arranged in the bottom and the slots of the outer box; and the inner box and the outer box are connected and fixed with each other through the outward turned-over edges at the tops of the inner box and the outer box. According to the structure adopted by the sand box, the slots are formed in the four inner side surfaces of the outer box, and the isolating screen stencils are inserted in the slots, so that the isolating screen stencils are convenient to replaced after being damaged; and meanwhile, the strengthening ribs are arranged at the bottom, the middle and the top of the inner box, so that the strength of the sand box is enhanced.
Description
Technical field
The utility model relates to a kind of casting sandbox, relates in particular to a kind of negative-pressure flask of lost foam casting.
Background technology
The negative-pressure flask of the lost foam casting that traditional lost foam casting uses, its structure is interlayer type, namely adopts a division board that the sandbox inner chamber is isolated.Be drilled with intensive thousands of hole on the division board, isolation screen cloth (304 stainless (steel) wire) is fixed with bolt and iron plate.Vertical strengthening ribs on the sandbox mainboard has a lot of bars, all is to keep at a certain distance away vertically to be fixed on the sandbox mainboard.The sandbox of this structure, processing and replacing screen cloth are very difficult, and useful space effect is little; The vertical strengthening ribs dynamics is inadequate, and the processing welding is also difficult.
Summary of the invention
The utility model provides a kind of and changes screen cloth conveniently, the negative-pressure flask of the lost foam casting that sandbox intensity is high.
The utility model is by the following technical solutions: negative-pressure flask comprises interior case and outer container, interior case is located in the outer container, described interior case bottom and the outside, middle part are respectively equipped with flat reinforcement, the top is provided with the angle stiffener that turns up, outer box top is provided with flanging, its four medial surfaces are provided with slot, in outer container bottom and the slot isolation screen cloth are set respectively, and interior case and outer container are connected and fixed by the flanging at both tops.
Described isolation screen cloth is 304 stainless (steel) wires.
Described isolation screen cloth be two-layer more than.
The utility model adopts above structure, utilizes four medial surfaces of outer container to be provided with slot, the isolation screen cloth of planting, and the replacing when convenient isolation screen cloth damages arranges reinforcement at interior case bottom, middle part and top simultaneously, has increased the intensity of sandbox.
Description of drawings
Now by reference to the accompanying drawings the utility model is further specified:
Figure l is the sectional structure schematic diagram of the utility model negative-pressure flask;
Fig. 2 is the plan structure schematic diagram of the utility model negative-pressure flask outer container.
The specific embodiment
Shown in Fig. 1 or 2, the utility model comprises interior case 1 and outer container 2, interior case 1 is located in the outer container 2, described interior case 1 bottom and the outside, middle part are respectively equipped with flat reinforcement 11,12, and the top is provided with the angle stiffener 13 that turns up, and outer container 2 tops are provided with flanging 21, its four medial surfaces are provided with slot 22, outer container 2 bottoms and the slot 22 interior isolation screen clothes 3,4 that arrange respectively, described isolation screen cloth 3,4 is iron screen cloth or copper screen cloth, described isolation screen cloth 3,4 be two-layer more than.Interior case 1 and outer container 2 are connected and fixed by the flanging at both tops.
