Pouring system with gate runner

Abstract

The invention discloses a pouring system with a gate runner and belongs to the fields of pouring systems. The existing pouring system adopts a dross filter so that a cost of dross filtration is high and a casting produces doped grid wires easily. The pouring system with a gate runner comprises an outer pouring gate, a sprue, the gate runner and ingates. The pouring system with the gate runner is characterized in that the top of the gate runner is provided with gates; front sides of the gates form slag retention spaces; and lower sides of the gates form a runner of which the cross area is reduced. The pouring system with the gate runner has the advantages that the gates can be directly made on a runner wood mold and be formed with a casting mold in molding sand feeding so that a dross filter purchase cost is reduced and economic benefits are obvious; a molding sand feeding process is more convenient than dross filter arrangement so that popularization and utilization are promoted; and good slag blocking effects are obtained only through control of gate height and a distance between at least two gates, wherein the control of gate height and a distance between at least two gates is carried out by a process designer according to demands.

Description

technical field [0001] The invention belongs to a gating system, in particular to a gating system with a gate runner, which ensures the purity of molten iron flowing into a mold cavity by blocking the molten slag through the gate. Background technique [0002] A general gating system is composed of an outer sprue, a sprue, a runner, and an inner runner that are connected in sequence. The molten iron is poured from the outer sprue, and flows into the mold through the sprue, the runner, and the inner runner ( cavity) to form a casting after solidification. To obtain high-quality castings, the runner must have a strong slag-retaining effect, so that high-purity molten iron flows into the mold, which can prevent castings from being scrapped due to casting defects such as slag holes and slag inclusions. In this way, the quality of the castings is guaranteed, the scrap rate is reduced, and the economic benefits are improved. It has been successfully applied to large-scale wind po...
