Abstract
An investment casting pouring system of a small casting comprises a sprue cup and a sprue which are connected, wherein a plurality of cross runners are arranged on the sprue and distributed at intervals, the cross runners are in a hollow spiral shape, one end, far away from the sprue cup, of each cross runner is connected with the sprue through a transition runner, a slag filter groove is arranged on the inner spiral surface of each cross runner, and a plurality of casting wax mold welding surfaces are distributed on the outer spiral surface of each cross runner; the utility model discloses structural design is ingenious, simple and practical, can effectively improve the metal liquid and fill type, pushing off the slag effect at the pouring in-process, promotes the foundry goods quality, can realize the tree group technology of flexibility simultaneously, promotes the technology yield of smallclothes, reduction in production cost.
Description
Technical Field
The utility model belongs to the technical field of the investment casting gating system and specifically relates to an investment casting gating system of miniature foundry goods.
Background
In investment casting, the design of the gating system plays a crucial role in production efficiency and quality of castings. At present, a sprue system of a sprue-ingate type or a cross sprue-ingate type is mostly adopted in investment casting, risers are added to partial products with complex structures to form a combined sprue system, the sprue systems are weak in slag blocking capacity, the casting quality problem is easily caused by serious molten metal turbulence phenomenon in the pouring process, and meanwhile, for single-weight small castings, the process yield is low and the production cost is high.
Disclosure of Invention
For solving that investment casting gating system pushing off the slag ability weak, pouring in-process metal liquid turbulent flow, simultaneously for promoting small casting technology yield, reduction in production cost's demand, the utility model provides an investment casting gating system of small casting.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an investment casting gating system of small casting, includes pouring basin and the sprue that connects, its characterized in that: be equipped with a plurality of interval distribution's cross gate on the sprue, the cross gate is hollow heliciform, and the one end of keeping away from the pouring basin on the cross gate is connected with the sprue through the transition runner, is equipped with the filter residue groove on the interior helicoid of cross gate, and it has a plurality of foundry goods wax matrix weld faces to distribute on the outer helicoid of cross gate.
The technical scheme is further limited, the number of turns of each cross gate is one, the spiral surface of each cross gate gradually and stably rises from the lower end to the higher end, and a spiral split ring is formed; the cross pouring channel with the circle structure can further improve the mold filling and slag stopping effects, and is beneficial to improving the casting quality.
The utility model has the advantages that: 1) helical runner: the molten metal can be stably filled from bottom to top, the turbulence phenomenon is eliminated, and the quality of the casting is improved; 2) a slag filtering groove: slag oxide in molten metal can be adsorbed on the slag filtering groove with the concave-convex structure, so that the quality of the casting is improved; 3) welding surfaces of the casting wax molds: the welding surfaces are not on the same plane and height, so that variable welding surfaces are formed, the number of the welding surfaces can be adjusted according to actual requirements, flexible adaptation can be realized according to the structure of a casting, the process yield is improved to the maximum extent, and the production cost is reduced; the utility model discloses structural design is ingenious, simple and practical, can effectively improve the metal liquid and fill type, pushing off the slag effect at the pouring in-process, promotes the foundry goods quality, can realize the tree group technology of flexibility simultaneously, promotes the technology yield of smallclothes, reduction in production cost.

Detailed Description
As shown in fig. 1 and fig. 2, an investment casting gating system for small castings comprises a sprue cup 1 and a sprue 2 which are connected, wherein the sprue is provided with three hollow spiral runners 3 which are distributed at intervals, the number of turns of each runner is one, and the spiral surface of each runner gradually and stably ascends from the lower end to the higher end to form an open ring similar to a spiral shape; the one end of keeping away from the pouring basin on the cross gate is connected with the sprue through transition runner 4, and the low side of cross gate is connected with the sprue through transition runner promptly, is equipped with multiunit concave-convex structure's slag trap 5 on the radial internal helicoid of cross gate, and it has a plurality of foundry goods wax matrix weld faces 6 to distribute on the radial outer helicoid of cross gate, and the foundry goods wax matrix 7 carries out module group tree on being connected to the weld face through ingate 8.
The details not described in the present specification are conventional in the art.
Claims (2)
