Disclosure of Invention
The utility model aims to: aiming at the defects and shortcomings of the prior art, the utility model provides a novel pouring structure, through a multilayer pouring structure, timely feeding can be performed according to the structural characteristics of castings, the thin-wall castings with the thickness of 4-5mm can be guaranteed to be completely poured, and the yield of the castings is improved; can realize the casting molding of large and medium thin-wall castings with the length of more than 1 meter.
The technical scheme is as follows: the utility model relates to a novel pouring structure, which is characterized in that: the multi-layer stepped annular pouring structure comprises an upper dendritic runner and a lower annular runner, wherein the dendritic runner is connected with the annular runner through a plurality of straight runners; the dendritic cross runner is connected with the pouring cup, and the dendritic cross runner and the annular cross runner are provided with air outlet holes and inner runners.
The branch-shaped cross gate comprises 2 cross gates and a plurality of inclined gates, and the air outlet holes are formed in the end parts of the branch-shaped cross gate.
The pouring cup is funnel-shaped with a wide upper part and a narrow lower part, and is communicated with the dendritic runner.
Wherein, the sprue is vertically arranged, and the sprue is communicated with the dendritic cross runner at the upper layer and the annular cross runner at the lower layer.
Wherein, the sprue is provided with a plurality of ingates.
Wherein, the annular cross gate is provided with a plurality of inner gates facing inwards.
Wherein, thin wall tin bronze foundry goods is located the dendritic runner and cyclic annular runner's coverage.
The beneficial effects are that: compared with the prior art, the utility model has the following remarkable advantages: the multi-layer stepped annular pouring system can timely feed according to the structural characteristics of castings, ensure that 4-5mm thin-wall castings can be completely poured, and improve the yield of the castings. The annular pouring system can enable copper liquid to fill the sand mold cavity rapidly and stably through the multi-layer pouring structure, pouring temperature can be properly reduced in the casting process, and casting defects of shrinkage porosity and shrinkage cavity can be reduced due to low pouring temperature. The multi-layer stepped annular casting system can realize the casting molding of large and medium thin-wall castings with the thickness of more than 1 meter, and the wall thickness of the castings is reduced from 8-10mm to 4-5mm, so that the production cost of the castings is reduced.

Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings and the specific embodiments.
The utility model develops a novel pouring structure aiming at the problems of unreasonable setting of a pouring system of a thin-wall tin bronze casting in the prior art, general casting quality, low product yield, thicker wall thickness of the tin bronze casting with more than 1 meter, higher cost and the like, which are limited by the process of the pouring system.
The novel pouring structure adopts a multi-layer stepped annular pouring structure and comprises an upper dendritic runner 3 and a lower annular runner 5, wherein the dendritic runner 3 and the annular runner 5 are connected through a plurality of straight runners 6; the dendritic cross runner 3 is connected with the pouring cup 2, and the dendritic cross runner 3 and the annular cross runner 5 are provided with an air outlet hole 1 and an inner runner 4. The dendritic cross runner 3 comprises 2 cross runners and a plurality of inclined runners, and the air outlet hole 1 is formed in the end portion of the dendritic cross runner 3. The pouring cup 2 is funnel-shaped with a wide upper part and a narrow lower part, and the pouring cup 2 is communicated with the dendritic runner 3. The straight pouring gate 6 is vertically arranged, and the straight pouring gate 6 is communicated with the dendritic transverse pouring gate 3 at the upper layer and the annular transverse pouring gate 5 at the lower layer. The sprue 6 is provided with a plurality of ingates 4. The annular runner 5 is provided with a plurality of inward ingates 4. The thin-wall tin bronze casting is positioned in the coverage range of the dendritic runner 3 and the annular runner 5.
The multi-layer stepped annular pouring system can timely feed according to the structural characteristics of castings, ensure that 4-5mm thin-wall castings can be completely poured, and improve the yield of the castings. The annular pouring system can enable copper liquid to fill the sand mold cavity rapidly and stably through the multi-layer pouring structure, pouring temperature can be properly reduced in the casting process, and casting defects of shrinkage porosity and shrinkage cavity can be reduced due to low pouring temperature.
