Description

Technical Field

[0001] This utility model relates to a lightweight anti-splash pouring cup, belonging to the field of wet sand casting technology. Background Technology

[0002] Moist sand casting is one of the most commonly used processes in sand casting. It mainly uses moist sand (wet molding sand) as the molding material to make the mold. The sand mold (core) does not need to be dried and can be used directly for pouring molten metal.

[0003] Traditional vertical pouring cups for wet sand casting often use cylindrical or conical shapes, which present problems such as splashing and turbulence during the pouring process, affecting the quality of the cast product. Furthermore, the large amount of molten iron consumed by the pouring cup results in low iron utilization and increases production costs. Therefore, this invention provides a lightweight, anti-splash pouring cup that can solve all of the above problems simultaneously. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a lightweight anti-splash pouring cup, which can avoid the phenomena of splashing and turbulence of molten iron during the pouring process, while the pouring cup occupies a small amount of molten iron and has a high molten iron utilization rate.

[0005] The lightweight anti-splash sprue cup of this utility model includes a cup body, which is installed on the top of a vertical mold. The cup body is composed of two identical half-cup bodies joined together. Both sides of the lower part of the half-cup body are provided with a horizontal sprue connector for connecting to the horizontal sprue, and the bottom of the half-cup body is provided with a vertical sprue connector for connecting to the vertical sprue. The cross-sections of both the horizontal sprue connector and the vertical sprue connector are trapezoidal to facilitate connection with the horizontal sprue and vertical sprue of the gating system.

[0006] The outer edge of the top of the assembled cup is round to facilitate the introduction of molten iron into the pouring system. The diameter of the top of the cup can be adjusted according to the pouring speed. There is a regular hexagonal opening in the center of the top of the cup. There is an arc transition section in the middle of the cup, which connects the top and bottom of the cup to form a complete pouring cup.

[0007] The technical solution of this utility model is to provide a lightweight anti-splash pouring cup. The cup body is installed on the top of a vertical mold, and one half-cup is placed on one side of the mold. The two half-cup bodies form a complete cup body. The horizontal runner joint of one half-cup body is connected to the horizontal runner, and the vertical runner joint is connected to the vertical runner. Molten iron is added through the regular hexagonal opening at the top of the cup body, flows through the runner, and enters the mold to complete the pouring. The molten iron is buffered by the cavity of the other half-cup body to avoid splashing and turbulence during the pouring process. At the same time, the arc transition part can reduce the volume of the cup body cavity. Therefore, this utility model has a small amount of molten iron required, a high molten iron utilization rate, and reduces production costs.

[0008] Preferably, the arc transition portion uses an R30 arc for the transition.

[0009] Preferably, the bottom width and height of the trapezoidal cross-section of the horizontal runner joint and the vertical runner joint are equal, both being F, and the top dimension of the trapezoidal cross-section of the horizontal runner joint and the vertical runner joint is E, and F = 2*E.

[0010] Preferably, the height C between the top surface of the cup body and the lower edge of the horizontal runner joint is between 66-92mm.

[0011] Preferably, the dimensions of C, E, and F in the cup can be adjusted according to the size of the product being poured, thereby achieving matching of the pouring rhythm.

[0012] The advantages of this utility model compared with the prior art are:

[0013] The lightweight anti-splash pouring cup of this utility model has a horizontal sprue joint connected to the horizontal sprue and a vertical sprue joint connected to the vertical sprue during use. Molten iron is added through the regular hexagonal opening at the top of the cup body, and the molten iron is buffered through the cavity of the other half of the cup body to avoid splashing and turbulence during pouring. At the same time, the arc transition part can reduce the volume of the cup body cavity. Therefore, this utility model has a small amount of molten iron required, a high molten iron utilization rate, and reduces production costs. Attached Figure Description
