Example Embodiment

As shown in Figures 1 and 2, an anti-sand pouring channel includes a runner 1 connected to the casting cavity 5 and a sprue 2 connected to the runner. The bottom of the sprue 2 is provided with The arc platform 3 is provided with a sprue bowl 4 on the arc platform 3. The sprue bowl 4 adopts a ceramic structure. During casting, the molten metal rushes from the top of the sprue 2 to the sprue bowl 4 at the bottom of the sprue 2 to prevent sand loss, avoid sand inclusion in the casting, and improve the quality of the casting.

Abstract

The invention provides a pouring channel capable of preventing sand drop, comprising a runner connected with a casting chamber, and a sprue connected with the runner; wherein the bottom of the sprue is provided with an arc platform, and a pouring gate bowl is arranged on the arc platform. Molten metal rushes into the pouring gate bowl at the bottom of the sprue from the top of the sprue, so that sand drop is prevented, the sand is prevented from being contained in the casting, and quality of the casting is improved.

Description

An anti-sand pouring channel technical field The invention relates to the field of casting, in particular to a pouring channel for preventing sand loss. Background technique The pouring channel is an important part of introducing molten metal into castings, and the unreasonable design of the pouring channel will lead to serious product quality problems. The existing pouring channel includes a sprue and a runner, the two are directly connected, and the molten metal rushes in from the top of the sprue, forming a large impact force at the bottom of the sprue, where it is also very easy to wash sand, resulting in castings Defects such as sand inclusions reduce the quality of castings. Contents of the invention The technical problem to be solved by the present invention is to provide a pouring channel for preventing sand loss, which can prevent sand loss, avoid sand inclusion in castings, and improve the quality of castings. In order to solve the above-mentioned existing ...
