Gating system with wall-mounted gating riser and working method thereof

Abstract

The invention discloses a gating system with a wall-mounted runner riser. The gating system comprises a sand mold and a runner, wherein the sand mold comprises a product part and a riser part; the product part is connected with the riser part; the runner comprises a main runner and a side runner; the upper riser part and the lower riser part communicate through the main runner; the side runner isarranged on the sides of the main runner and the riser part; the bottom of the side runner communicates with the main runner; and pouring liquid flows into the main runner, the riser part and the product part from the bottom of the side runner. Since the side runner is located outside the riser part, space does not need to be occupied independently, thus effectively reducing the space occupied bythe riser and the runner and improving the production efficiency by 50%. By pouring from bottom to top, mixed bubbles in molten iron can be prevented. According to the gating system, the lateral runner is arranged outside the riser part, so that the riser can be effectively prevented from cooling in the product cooling process, and the cooling time of the riser is fully ensured to be longer than that of the product, thereby effectively ensuring feeding and avoiding defects such as slag holes.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a gating system for a wall-attached sprue riser. Background technique [0002] The main function of the riser is to feed shrinkage. Since the cooling and forming process of the casting will produce volume shrinkage, the riser will supply molten iron when the casting is formed to prevent internal defects such as shrinkage cavities and shrinkage porosity. Generally, in order to prevent the molten iron from damaging the sand mold and producing slag holes, the riser will introduce molten iron at the bottom and side, such as figure 1 , but the space occupied by the riser and the sprue is large, which is not conducive to the process layout and the production efficiency is low. Contents of the invention [0003] In view of the deficiencies of the above-mentioned prior art, the purpose of the present invention is to reduce the space occupied by the riser and the runner, and avoid defe...
