Description

Technical Field

[0001] This utility model relates to the field of gravity casting, specifically to a gating basin for gravity tilting casting. Background Technology

[0002] In gravity tilting casting, low-pressure casting uses riser pipes to pressurize clean molten metal from the bottom of the holding furnace into the mold cavity. Slag can be avoided in gravity casting via the gating system. Tilting casting is a popular casting method in recent years, where molten aluminum is poured directly from the gating bowl into the mold cavity by tilting the equipment. Currently, the gating bowls used in gravity tilting casting include... Figure 1 As shown, due to the lack of a slag-blocking and filtering device, this type of pouring basin has the following problems:

[0003] 1. If the surface of the sprue basin has oxide scale and oxide residue, the gold liquid will enter the mold cavity along with the surface layer.

[0004] 2. Turbulent flow of slag from the gating bowl into the mold cavity causes severe slag inclusion in the product;

[0005] 3. The filling speed is uncontrollable due to the tilting speed, making it difficult to adjust for stable filling.

[0006] Therefore, a sprue bowl that can prevent residues in the molten aluminum from entering the mold cavity is needed. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a gravity-driven tilting pouring basin. This basin prevents slag from entering the mold cavity, thus ensuring the quality of the molten aluminum.

[0008] The purpose of this utility model is achieved by the following solution: a gravity tilting pouring sprue basin, including a sprue basin connecting plate fixed to the mold, a sprue basin is provided on the upper end surface of the sprue basin connecting plate, the sprue basin includes a bottom of the sprue basin and a side wall of the sprue basin extending along the edge of the bottom of the sprue basin, the space between the bottom of the sprue basin and the side wall of the sprue basin is a space for holding molten aluminum, the sprue basin includes a sprue basin inlet area provided at the front end of the sprue basin and a sprue basin outlet area provided at the rear end of the sprue basin, a slag baffle is provided between the sprue basin inlet area and the sprue basin outlet area, the left and right ends of the slag baffle are respectively fixed to the left and right side walls of the sprue basin, an outlet is left between the bottom of the slag baffle and the inner side wall of the rear end of the sprue basin, a filter screen seat connecting bracket is provided at the upper end of the outer side wall of the front end of the sprue basin, the filter screen seat connecting bracket is fixed to the filter screen, and the filter screen is provided above the sprue basin inlet area.

[0009] The gating basin connecting plate is integrally formed with the gating basin.

[0010] The pouring basin connecting plate is connected and fixed to the mold by bolts.

[0011] The bottom of the pouring basin is provided with a weight-reducing groove, and a reinforcing rib is provided between the outer wall of the rear end of the pouring basin and the pouring basin connecting plate.

[0012] The pouring basin is made of cast iron QT400-600.

[0013] The advantage of this invention is that the pouring basin has a simple structure and can prevent oxide scale and slag on the surface of the pouring basin from flowing into the riser, thus ensuring the quality of the molten aluminum and preventing slag inclusions in the product.

[0018] like Figures 2 to 4 As shown, a gravity tilting pouring gating basin includes a gating basin connecting plate 6 that is fixedly connected to the mold. The gating basin connecting plate 6 is fixedly connected to the mold by bolts 5. A gating basin is provided on the upper end surface of the gating basin connecting plate 6, and the gating basin connecting plate 6 and the gating basin are integrally formed. The pouring basin includes a bottom and sidewalls extending along the edge of the bottom. The space between the bottom and sidewalls is for holding molten aluminum. The pouring basin includes a liquid inlet area 2 at the front and a liquid outlet area 4 at the rear. A slag baffle 3 is installed between the liquid inlet area 2 and the liquid outlet area 4. The left and right ends of the slag baffle 3 are connected and fixed to the left and right sidewalls of the pouring basin, respectively. A liquid outlet 7 is provided between the bottom of the slag baffle 3 and the inner sidewall of the rear end of the pouring basin. A filter screen holder connecting bracket 1 is installed at the upper end of the outer sidewall at the front of the pouring basin. The filter screen holder connecting bracket 1 is connected and fixed to the filter screen, which is positioned above the liquid inlet area 2. A weight-reducing groove 8 is provided at the bottom of the pouring basin, and a reinforcing rib 9 is provided between the outer sidewall of the rear end and the pouring basin connecting plate 6. The pouring basin is made of cast iron QT400-600.

[0019] The molten metal is poured into the inlet area of ​​the gating basin, passes through the outlet at the bottom of the baffle plate, and the clean molten metal enters the outlet area of ​​the gating basin, where it is turned over and flows into the mold cavity. At the same time, the oxide slag on the surface of the inlet area of ​​the gating basin is blocked by the baffle plate and finally enters the riser in the mold cavity, preventing slag inclusions in the product.
