Embodiment Construction

[0013] See Figure 1 to Figure 6 , the gating system 10 for solving the uneven inflow of the ingate includes a sprue 20 , a runner 30 and an ingate 40 , the upper end of the sprue 20 is used to connect the sprue basin, and the lower end is connected to the runner 30 , The bottom end of the sprue 20 is provided with a buffer dimple 201 for buffering molten iron. The cross-sectional area of ​​the buffer dimple 201 is larger than that of the sprue 20, and the cross-section of the buffer dimple 201 and the cross-section of the sprue 20 are concentric circles. , the upper end surface of the joint between the runner 30 and the sprue 20 is flush with the top surface of the buffer dimple 201, the buffer dimple 201 can buffer the impact of the molten iron, and shorten the iron at the corner of the sprue 20 and the runner 30. liquid turbulence zone, thereby guiding the molten iron to flow into the runner 30 smoothly and slowly.

[0014] See Figure 1 to Figure 6 , the runner 30 is a l...

Abstract

A gating system capable of solving inner runner inflow unevenness comprises a straight runner, a transverse runner and inner runners. The upper end of the straight runner is used for being connected with a pouring basin, and the lower end thereof is connected with the transverse runner. The transverse runner is a horizontal passage vertical to the straight runner. The upper surface of the transverse runner is a plane, the lower surface of the transverse runner is stepped, the longitudinal section of the transverse runner is variable, and the longitudinal section area gradually decreases from one end, close to the straight runner, to one end, away from the straight runner. The inner runner is vertical to the transverse runner. During cast pouring, molten iron flows slowly in the transverse runner, molten iron level rises stably, the molten iron reaches the inner runners at the same time and enters the inner runners at the same time, stable and even flow speed is achieved, molten iron splashing and jetting are avoided, risks of curling up and sand cut are lowered greatly, reliable cast quality is achieved, and yield is increased greatly.

Description

technical field [0001] The invention relates to the technical field of casting pouring, in particular to a pouring system for solving uneven inflow of an inner runner. Background technique [0002] Usually, the customary gating system used in gating system design is that the sprue, runner and inrunner are all of constant cross-sectional area. For the gating system with multiple inlets, the molten iron enters from the sprue , after flowing into the runner, it always rushes directly to the end of the runner, and takes the lead in flowing from the inner runner far away from the sprue, which makes the molten iron entering from the sprue not evenly distributed to each inner runner, In this way, the flow rate of each ingate is relatively fast, which also increases the risks of air entrainment, sand flushing, and splashing, resulting in defects such as pores and sand inclusions, resulting in poor casting quality. Contents of the invention [0003] It is necessary to provide a ga...
