Problems solved by technology

[0002] The casting mold has a cavity and a sprue. After the pouring is completed, the casting will shrink, and the pouring liquid in the sprue will drop. In the case of a small casting, the pouring liquid in the sprue can meet the requirements, but there are The castings are relatively large, and this part of the pouring liquid cannot meet the requirements, which often leads to waste products. In order to prevent the lack of pouring liquid, a feeding chamber is set up. In the prior art, the feeding chamber is set separately on the mold. Such a mold It has the disadvantage of many parts, and the formed green body needs to cut the extra part in the feeding chamber, which has the disadvantage of troublesome processing

Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing.

[0011] Such as figure 1 As shown, a casting mold with a feeding chamber includes a mold body 1, the mold body has a cavity 2 and a sprue 3, and a pouring tube 4 is connected to the sprue and the cavity, and the feature is: in the spouting tube There is an enlarged small chamber 5 in the middle, and said small chamber is exactly an enlarged cavity.

[0012] In this way, since there is no need to set up a feeding chamber separately, after the green body is formed, there is only one redundant part, that is, the part where the pouring pipe is connected, so that the processing is easy.

[0013] Further, the volume of the small chamber is 1 / 100 of the cavity volume. This can ensure the function of the feeding chamber without causing waste.

[0014] Further, the distance between the bottom of the small chamber and the upper part of the cavity is 1-1.5 cm. This ensures that the...

Abstract

The invention relates to the technical field of casting, in particular to a casting die with a feeding chamber. The casting die with the feeding chamber comprises a die body. The die body is provided with a cavity and a casting opening. A casting pipe is connected with the casting opening and the cavity. A small chamber which can becomes larger is formed in the middle of the casting pipe. The volume of the small chamber is 1% of the volume of the cavity. The distance between the bottom of the small chamber and the upper portion of the cavity is 1-1.5 cm. By the adoption of the structure, the casting die with the feeding chamber has the advantages that the number of components is small, and machining is easy.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a casting mold. Background technique [0002] The casting mold has a cavity and a sprue. After the pouring is completed, the casting will shrink, and the pouring liquid in the sprue will drop. In the case of a small casting, the pouring liquid in the sprue can meet the requirements, but there are The castings are relatively large, and this part of the pouring liquid cannot meet the requirements, which often leads to waste products. In order to prevent the lack of pouring liquid, a feeding chamber is set up. In the prior art, the feeding chamber is set separately on the mold. Such a mold It has the disadvantage of many parts, and the formed green body needs to cut the excess part in the feeding chamber, which has the disadvantage of troublesome processing. Contents of the invention [0003] The object of the present invention is to address the above disadvantages and provide a ...
