Abstract
The utility model relates to an assembling structure of a riser bush special for shell castings, which comprises a prefabrication cavity arranged on a wet sand mold and a riser bush embedded in a cavity. The assembling structure of the riser bush special for shell castings is characterized in that the lower end of the riser bush is provided with a protrusion, the protrusion is a skirt-shaped protrusion or a flange-shaped protrusion, and a sand-pressing ring matched with the protrusion is positioned on the prefabrication cavity. The assembling structure adopts a structure that the protrusion is matched with the sand-pressing ring, thereby realizing accurate location of the riser bush in the cavity, separating liquid metal under a main body of the riser bush, avoiding forming jacketing on the riser bush, and effectively increasing casting product rate. The boiling defect caused by jacketing and using an exothermic riser in molding process of castings is avoided, thereby having no effects on the molding quality of castings. Meanwhile, mixed materials produced by jacketing scrap returns of different materials are avoided, thereby effectively improving economic benefits of casting productions.

Background technology
Rising head is to be located to supply in the casting mold to store the feeding a casting motlten metal in foundry goods manufacturing process, and the cavity of exhaust, the effect of collection slag is arranged.In actual production process, for improving the product yield of foundry goods, reduce the molten metal in the rising head, the insulating riser sleeve of being made by insulation material or refractory material is set in the position of rising head usually or the exothermic riser sleeve of being made by pattern of fever material occurred frequently is set.At present, riser buss commonly used in the shell casting formula is produced is a cup-like structure, the step that riser buss is installed in casting mold is: produce earlier the die cavity consistent with the riser buss shape 1 on the tide mould sand type in advance, then riser buss 2 is bonded at or is placed on the shell mould, the mode of having organized the following core of shell mould of core is placed on the tide mould sand type, riser buss and above-mentioned prefabricated die cavity are aligned.Reason owing to assembling, must leave the certain clearance amount between above-mentioned riser buss and the prefabricated die cavity, but when cast, molten metal overflows from the seam crossing of riser buss and shell mould very easily, make all or part of molten metal that is full of in gap between riser buss and the prefabricated die cavity, the cooling back forms involucrum.When using exothermic riser,, thereby reduce quality of castings owing to above-mentioned involucrum produces the fiery defective of choking.Because involucrum is thinner, come off easily during knockout in addition, very easily cause the foundry returns of unlike material to obscure, reduce the manufacturing cost of the yield rate and the raising foundry goods of foundry goods.
Summary of the invention
The utility model provides a kind of accurate location, prevents that molten metal from entering the gap between riser buss and the prefabricated die cavity for solving the technical problem that exists in the known technology, and then eliminates the special-purpose riser buss assembly structure of shell casting of the fiery defective of choking.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The special-purpose riser buss assembly structure of a kind of shell casting, comprise the prefabricated die cavity that is located on the tide mould sand type and embed the interior riser buss of die cavity, it is characterized in that: described riser buss lower end is shaped on projection, described projection is a skirt shape projection, the lower end of described prefabricated die cavity is provided with the consistent inclined-plane of skirt hypotenuse angle with projection, is shaped on the pressure sand ring that cooperates with the skirt hypotenuse of projection on the described inclined-plane.
Described skirt shape projection bottom and riser buss main part have the pattern draft of equidirectional.
Described skirt shape projection bottom and riser buss main part have rightabout pattern draft.
The technical scheme that the utility model can also be taked is:
The special-purpose riser buss assembly structure of a kind of shell casting, comprise the prefabricated die cavity that is located on the tide mould sand type and embed the interior riser buss of die cavity, it is characterized in that: described riser buss lower end is shaped on projection, described projection is the flange-like projection, is shaped on the pressure sand ring that matches with the upper surface of projection on the lower surface of described prefabricated die cavity.
Described flange-like projection has the pattern draft of equidirectional with the riser buss main part.
Described flange-like projection has rightabout pattern draft with the riser buss main part.
Advantage and the good effect that the utlity model has are:
The utility model is by being shaped on skirt shape or flange-like projection in the riser buss lower end, the pressure sand ring that cooperates with above-mentioned projection is set on prefabricated die cavity, realize the accurate location of riser buss in die cavity, molten metal is intercepted below the riser buss main part, avoid on riser buss, forming involucrum, effectively improve the casting yield rate; Avoid foundry goods in forming process, to use exothermic riser, influence the Forming Quality of foundry goods owing to the involucrum fiery defective that occurs choking; Avoid the involucrum foundry returns of unlike material to produce batch mixing simultaneously.Effectively improve the economic benefit of Foundry Production.
