In order to achieve the above object, the utility model adopts the following technical solutions:

A new sprue cup for large-scale wind power castings, including a sand mold body, the sand mold body is a cuboid groove-shaped structure, a slag retaining plate is arranged in the middle of the sand mold body, and the slag retaining plate separates the sand mold body into two parts, A downwardly recessed stabilizing groove is provided between the bottom of the slag retaining plate and the bottom surface of the sand mold body.

In particular, one part of the sand mold body is an iron inlet, and the other part is an iron tap.

In particular, the taphole extends to the bottom of the sand mold.

In particular, the slag retaining plate is fixedly connected with the sand mold body.

In particular, the slag retaining plate is made of refractory materials.

In particular, the sprue cup is 500mm high, 800-950mm long, and 480-550mm wide.

The beneficial effects of the utility model are:

1. The structure of the new sprue cup is simple, and the outer frame can be reused to save cost.

2. The steady flow groove provided at the bottom of the new sprue cup can ensure that the pouring liquid enters the sprue effectively and smoothly, and the steady flow effect is good.

3. During the pouring process of the slag retaining plate set by the sprue cup, it can effectively reduce defects such as slag inclusion and sand inclusion in the casting process of the casting, and the slag retaining effect is outstanding.

4. The manufacturing cost of the new sprue cup is low, and the skill requirements for on-site workers are low, so it is suitable for mass production.

detailed description

In order to clearly illustrate the technical features of this solution, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

Example 1

A new sprue cup for large-scale wind power castings, as shown in Figure 1 and Figure 2, includes a sand mold body, the sand mold body is a cuboid groove structure, and a slag retaining plate is arranged in the middle of the sand mold body, and the slag retaining plate will The sand mold body is divided into two parts, and a downwardly concave stabilizing groove is arranged between the bottom of the slag retaining plate and the bottom surface of the sand mold body.

One part of the sand mold body is an iron inlet, and the other part is an iron outlet.

The taphole extends to the bottom of the sand mold.

The slag retaining plate is fixedly connected with the sand mold body.

The slag retaining plate is made of refractory material.

The sprue cup is 500mm high, 900mm long and 520mm wide.

Example 2

A new sprue cup for large-scale wind power castings, as shown in Figure 1 and Figure 2, includes a sand mold body, the sand mold body is a cuboid groove structure, and a slag retaining plate is arranged in the middle of the sand mold body, and the slag retaining plate will The sand mold body is divided into two parts, and a downwardly concave stabilizing groove is arranged between the bottom of the slag retaining plate and the bottom surface of the sand mold body.

One part of the sand mold body is an iron inlet, and the other part is an iron outlet.

The taphole extends to the bottom of the sand mold.

The slag retaining plate is fixedly connected with the sand mold body.

The slag retaining plate is made of refractory material.

The sprue cup is 500mm high, 800mm long and 480mm wide.

Example 3

A new sprue cup for large-scale wind power castings, as shown in Figure 1 and Figure 2, includes a sand mold body, the sand mold body is a cuboid groove structure, and a slag retaining plate is arranged in the middle of the sand mold body, and the slag retaining plate will The sand mold body is divided into two parts, and a downwardly concave stabilizing groove is arranged between the bottom of the slag retaining plate and the bottom surface of the sand mold body.

One part of the sand mold body is an iron inlet, and the other part is an iron outlet.

The slag retaining plate is fixedly connected with the sand mold body.

The slag retaining plate is made of refractory material.

The sprue cup is 500mm high, 950mm long and 550mm wide.

The production method of the new sprue cup:

First, make a mold according to the shape of the new sprue cup, then place an iron frame the same size as the mold on the mold, use a sand mixer to fill the gap between the mold and the iron frame with sand and pound it tightly After the sand is hardened, take out the sand mold, put a slag retaining board fired with refractory materials into the mold and use sand to seal the gaps around the slag retaining board tightly, and coat the surrounding of the slag retaining board after the sand is hardened Paint, ready to use.

The working principle of the new sprue cup:

When pouring, the molten iron ladle is poured on the side away from the runner. The new sprue cup is filled quickly in the first few seconds of pouring. Since the density of the slag is lighter than that of the molten iron, the slag floats on the surface of the molten iron. During the subsequent pouring process, due to The slag retaining plate is in the middle, the slag will always float on the side away from the gate, the molten iron enters the gate through the bottom steady flow tank, and the floating slag inclusions will not enter the casting. This structure can effectively prevent the pouring molten iron from rushing directly to the runner cup, reduce the generation of broken sand and improve the quality of castings.

The shape of the original sprue cup is as shown in Figure 3 and Figure 4. The sprue cup simply plays the role of pouring the molten liquid into the runner. The iron inlet and the iron outlet are at the same position, and there is no slag blocking plate to stop the slag The effect and the steady flow effect of the steady flow tank.
