Example Embodiment

[0023] The present invention will be further described below with reference to the drawings and embodiments.

[0024] Such as Figure 4 As shown, a sand sprue cup mold for casting train wheels has a mold cover (9). The mold cover (9) is the upper core box of the floating core box commonly used in sand molding. The mold cover (9) is pressed tightly. On the lower mold box (2).

[0025] Such as figure 1 , image 3 , Figure 4 As shown, the bottom of the lower mold box (2) is fixed on the bottom plate (1) by screws (8); the inner side of the bottom of the lower mold box (2) has a cone-shaped protrusion (4), and the top of the cone-shaped protrusion (4) There is a cylindrical straight hole mold (7), the cone-shaped protrusion (4) and the straight hole mold (7) are a whole; the cone-shaped protrusion (4) is evenly distributed with exhaust plugs (5) on the outside of the bottom circumference; the bottom plate ( 1) There is a handle (3) on it. The central axis of the cone-shaped protru...

Abstract

The invention discloses a sand mold sprue cup die for casting a train wheel, which comprises a die cover and is characterized in that the die cover is of an upper core box of a float core box commonly used for casting a sand mold and is tightly pressed on a lower die box, the bottom of the lower die box is fixed on a bottom plate by a screw and is provided with a conical bulge at the inside, the conical bulge, provided with a cylindrical straight hole die at the top end, and the straight hole die are integral, venting plugs are uniformly distributed at the periphery outside of the bottom of the conical bulge, and a handle is arranged at the bottom plate. According to the sand mold sprue cup die for casting the train wheel, the fineness and strength of the contact surface between a sand mold sprue cup and steel liquid are higher, and a straight sprue of the sprue cup is round and complete and has no float sand.

Description

technical field [0001] The invention relates to a sand sprue cup mold for casting train wheels. Background technique [0002] After the bottom pouring bag pours the train wheel mold, use a sample spoon to scoop molten steel in the mold and pour it into a small model to form a sample, and then test the chemical composition of the sample to know whether the chemical composition of the train wheel meets the quality standards. A sand sprue cup is placed at the gate of the small model, and the function of the sand sprue cup is to accept the molten steel from the bottom casting bag and guide the molten steel into the small model. [0003] If the strength and smoothness of the sand sprue cup are not enough, the sand sprue cup washed by the high temperature of molten steel is very easy to be worn, and the part of the washed away material is carried into the small model by the molten steel, which is likely to cause the chemical composition of the sample to be different from that of t...
