Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0028] The gating system with the multi-stage split runner of the present invention includes a sprue cup, a sprue, a runner and an inner runner, and the runner includes at least two stages; each runner of each stage The midpoint of the runner is set as the split point, and the midpoint of the first-stage runner corresponds to the straight runner; each runner of each stage is symmetrically connected to two next-stage runners relative to the midpoint of the runner. Runner, the runner of the next level is perpendicular to the junction of the runner of the previous level; each runner of the last level is symmetrically connected with two inner runners relative to the midpoint of the runner, and the inner runner It is perpendicular to the connection with the last level runner.

[0029] The present invention utilizes the principle of symmetry and adopts th...

Abstract

The invention discloses a gating system with multistage split transverse runners, and belongs to the casting technology. The flow rates of the internal runners of the existing gating system are different, the transverse runners of the gating system disclosed by the invention comprises at least two stages; the central point of each transverse runner of each stage is set as a diverging point, and the central point of the first stage of transverse runners corresponds to a straight runner; each transverse runner of each stage is symmetrically connected with the next stage of two transverse runners relative to the central point of the transverse runner, and the next stage of transverse runners is vertical to the former stage of transverse runners at the communication sites; each transverse runner of the last stage is symmetrically connected with two internal runners relative to the central point of the transverse runner, and the internal runners are vertical to the last stage of transverse runners at the communication sites. According to the invention, multistage transverse runners are formed by the method of splitting the transverse runners, the two ends of the last stage of transverse runners are respectively communicated with one internal runner to finally form a gating system with the straight runner as a centre of symmetry, and the flow rate in each runner can be kept uniformly during casting.

Description

technical field [0001] The invention belongs to casting technology, in particular to a pouring system with multi-stage split runners. Background technique [0002] Casting is to melt metal into molten metal that meets certain requirements, and then pour it into a mold with a cavity of a specific shape (the casting term describing this process is called "pouring", and this cavity is called "cavity") , After solidification, cooling, unpacking and cleaning, etc., the process of obtaining blank parts with expected shape, size and physical and chemical properties. In order to pour liquid metal into the cavity, a process channel needs to be opened on the mold, which is the pouring system. The gating system usually includes sprue cups, sprues, runners and ingates. During pouring, the molten metal flows through the sprue cup, the sprue, the runner and the inner runner in turn, and finally enters the cavity. The gating system should allow the molten metal to enter the cavity smoot...
