Problems solved by technology

This type of sprue cup has good thermal insulation, but the junction between the sprue cup and the mold cannot be smoothly transitioned, and the molten metal flow is not stable enough when it enters the cavity, and it is easy to splash and generate oxidized slag inclusions, forming oxidized slag inclusion defects in castings. Greatly reduced the pass rate of the product
[0004] The second sprue cup type, such as the cross-section controllable sprue cup proposed by Wenzhou Ruiming Co., Ltd., has an application number of 201210443819.6. The wall thickness of this cast iron sprue cup is about 15mm, and its heat storage capacity is good. The gate section of the molten metal entering the cavity is fixed, but the

Abstract

The invention relates to a gravity rotated casting pouring basin, which comprises a pouring basin body, the pouring basin body comprises a bottom and a side wall outwardly extended along the edge of the bottom; the pouring basin body is divided into a liquid inlet zone, a liquid filling zone and a casting gate in order along the cast liquid flow; the bottom is divided into a liquid inlet zone bottom, a liquid filling zone bottom and a casting gate bottom which are smoothly connected; and the liquid inlet zone bottom is an impact inclined plane. The gravity rotated casting pouring basin is capable of improving the flow characteristic of molten metal in the pouring basin and realizing the stable state casting of the molten metal.

Description

technical field [0001] The invention belongs to the technical field of casting mold structure design, and relates to a gravity tilting casting sprue basin. Background technique [0002] There are generally two types of sprue basins for gravity tilt casting: [0003] The first one is the gravity tilting pouring machine thermal insulation sprue cup proposed by Harbin Dongan Automobile Co., Ltd., and its patent number is 201220755199.5. The sprue cup is made of thin steel double-layer steel plates welded into the sprue cup, and the hollow layer is filled with thermal insulation materials. This type of sprue cup has good thermal insulation, but the junction between the sprue cup and the mold cannot be smoothly transitioned, and the molten metal flow is not stable enough when it enters the cavity, and it is easy to splash and generate oxidized slag inclusions, forming oxidized slag inclusion defects in castings. Greatly reduced the pass rate of the product. [0004] The second...
