How to arrange a lightweight pouring channel in a wind power large casting product is a technical problem to be solved.
Disclosure of Invention
For the above-mentioned technical problem who exists among the example solution prior art the utility model provides a water the runner form structure, specifically do:
a lightweight pouring channel applied to wind power products comprises a main pouring gate, wherein the main pouring gate is positioned in a casting sand mold and is characterized in that the main pouring gate comprises a first vertical section, a horizontal connecting section and a second vertical section; the bottom ends of the first vertical section and the second vertical section are respectively connected with the head end and the tail end of the horizontal connecting section; the top end of the first vertical section is connected with a sprue of the casting sand mold; the horizontal connecting section is positioned below the cavity; the axis of the second vertical section is superposed with the central axis of the cavity; the side surface of the second vertical section is a molten iron outlet which is communicated with the bottom of the cavity; and the outermost end of the top of the cavity is provided with a riser and an exhaust port, and the riser and the exhaust port are communicated with the top of the casting sand mold through a molten iron flow path.
The cavity is in an axisymmetric structure, a molten iron flow path which communicates the second vertical section with the bottom of the cavity is in a shape of a thin pancake, the outer edge of the thin pancake-shaped molten iron flow path is communicated with the cavity, and the middle of the thin pancake-shaped molten iron flow path is connected with the second vertical section.
And a scum collecting cavity is arranged at the top of the second vertical section and is arranged above the molten iron outlet of the second vertical section.
Technical scheme principle explanation:
the lightweight pouring channel of the wind power product is characterized in that a structure (a cavity) is taken out by a wood mold during molding, and a molten iron flow path is directly made by the sand mold. The front end of the molten iron flow path is connected with the tail end of the straight pouring channel (main pouring channel), and the rear end of the molten iron flow path is directly connected with the cavity by self-feeding water, so that the molten iron can be directly filled.
The technical method has the advantages and beneficial effects that:
1. the technical scheme can realize the shortening of the molten iron mold filling path. Molten iron flowing out of the sprue passes through the upper end to collect slag, and then enters the cavity from the sheets (cake-shaped molten iron flow paths) on the two sides, so that the probability of sand washing of the sprue and formation of oxidation slag by air contact due to stirring of the molten iron is reduced, the product quality is effectively improved, and the rejection rate is reduced.
2. The technical scheme can reduce the consumption of raw materials and improve the yield of the molten iron of the casting.
3. The technical scheme can reduce the workload of modeling workers and post-processing workers and reduce potential safety hazards.
4. The technical scheme can realize simple structure and convenient operation.
Drawings
FIG. 1 is a schematic view showing a structure of a lightweight runner of this embodiment in a casting sand mold;
FIG. 2 is a schematic top view of the lightweight runner of the present embodiment;
FIG. 3 is a plan view of the molten iron flow path connecting the second vertical segment and the bottom of the cavity in this example;
in the figure: the casting sand mold comprises a first vertical section 1, a horizontal connecting section 2, a second vertical section 3, a cavity 4, a molten iron outlet 5 of the second vertical section, a riser/exhaust port 6, a molten iron flow path 7 for communicating the second vertical section with the bottom of the cavity, a scum collecting cavity 8 and a casting sand mold 9.
Detailed Description
The present disclosure is further described with reference to the following drawings and detailed description:
referring to fig. 2, the cast article of this example is irregular in shape, having a "bowl" shaped body with folds at its upper and lower edges facing away from the central axis, and a plurality of "notches" in the side walls of the body. The cavity is difficult to manufacture by adopting the traditional sprue and cross runner type structure, and even after the cavity which can be used for casting is manufactured, a plurality of cross runners are needed to inject molten iron into the cavity. In the scheme, the shape of the cavity is consistent with that of the casting.
By adopting the pouring channel, the second main pouring gate is arranged at the central position of the bottom surface of the bowl, and the cavity at the bottom of the bowl is used as a transverse pouring gate. Molten iron enters a cavity of the edge folding part at the lower part of the bowl and a cavity of the bowl wall part from the thin sheet position at the bottom of the bowl, gradually reaches the upper edge of the bowl from bottom to top and enters the cavity of the edge folding part at the lower part of the bowl, and the cavity is provided with a riser/an exhaust port.
