Slag blocking sprue for casting

Abstract

The invention discloses a slag blocking sprue for casting, which is high in manufacturing efficiency, can not cause waste of iron liquor, does not need additional fixed devices and can not lose the slag-blocking action in casting. The slag blocking sprue comprises a sprue main body (1), wherein the bottom part of the sprue main body (1) is provided with a groove which is arranged along the width direction of the sprue main body (1); a baffle part (7) which is integrated with the sprue main body (1) is arranged above the bottom part of the groove; at least one flowing unit (8) is buried between the baffle part (7) and the bottom part of the groove; all the flowing units (8) are provided with flowing holes (11) for communicating a first flow guiding groove (9) and a second flow guiding groove (10); the adjacent flowing units (8) are attached or a gap for flowing of the iron liquid is arranged between the adjacent flowing units (8); and the flowing units (8) are used for controlling the flowing rate of the iron liquid from the first flow guiding groove (9) to the second flow guiding groove (10).

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a slag blocking gate for casting. Background technique [0002] figure 1 , 2 Shown is the slag blocking gate for casting in the prior art, which is a split type or assembly type, that is, a slag blocking piece 5.1 is used to separate the inside of the gate body 1.1 into a pouring cavity 2.1 and a flow connected to the sprue 3.1. Cavity 4.1, slag stop piece 5.1 is fixedly connected with gate main body 1.1 through fixing device 6.1, such casting slag stop gate has the following disadvantages: 1. The production efficiency is low, that is, the gate body and slag stop piece need to be made separately first , Fixing device, after completion, assemble the slag blocking piece into the main body of the gate, and then fix it with the fixing device; 2. After the gate main body and the slag blocking piece are assembled together, there There are still gaps in the matching part of the gate,...

Problems solved by technology

[0002] figure 1 , 2 Shown is the slag blocking gate for casting in the prior art, which is a split type or assembly type, that is, a slag blocking piece 5.1 is used to separate the inside of the gate body 1.1 into a pouring cavity 2.1 and a flow connected to the sprue 3.1. Cavity 4.1, slag stop piece 5.1 is fixedly connected with gate main body 1.1 through fixing device 6.1, such casting slag stop gate has the following disadvantages: 1. The production efficiency is low, that is, the gate body and slag stop piece need to be made separately first , Fixing device, after completion, assemble the slag blocking piece into the main body of the gate, and then fix it with the fixing device; 2. After the gate main body and the slag blocking piece are assembled together, there There are still gaps in the matching part of the gate, so part of the molten iron will enter the gap during pouring, resulting in waste of molten iron; 3. Additional fixing devices are required. Since the main body of the gate and the slag blocking piece are not integrated, an additional fixing device needs to be made to block the slag. The slag is fixed on the gate body

4. The slag blocking sheet may float up, resulting in loss of slag blocking effect, that is, if the fixing device fails, the slag blocking sheet will float up under the buoyancy of the molten iron during the pouring process, so that the entire gate will lose the slag blocking effect
