The investment casting aluminum-copper alloy pouring system of Ningbo Suijin includes a sprue, the bottom of the sprue is connected with a runner, and the bottom of the runner is provided with a first buffer groove at a position corresponding to the sprue , The bottom of the runner is fixedly connected with a filter box, the bottom of the filter box is connected with a first inner runner, and the bottom of the filter box and located on the left side of the first inner runner is connected with a second inner runner The bottom of the filter box and the left side of the second inner runner is connected with a third inner runner, the end of the first inner runner away from the filter box is connected with a first connecting pipe, and the second inner runner The end of the sprue away from the filter box is connected with a second connecting pipe. The present invention solves the problem through the cooperation of the sprue, the cross runner, the filter box, the first inner runner, the second inner runner and the third inner runner. Traditional investment casting aluminum-copper alloy gating system has poor slag resistance, which directly affects the quality of castings.
The investment casting structure of Ningbo Suijin includes an investment main body, an investment core, a molding core, and an inner gate; the investment main body includes a support shaft, a first sleeve connected to one end of the support shaft, and a first sleeve connected to the other end of the support shaft. Two shaft sleeves; the investment core is built into the investment main body, the forming core is connected to the second shaft sleeve, and the inner gate is connected to the first shaft sleeve. The investment casting structure of this utility model is solved by embedding the investment core in the investment main body The problem of deformation of the investment mold due to its thickness is solved; the quality of the blind hole is ensured by the clamping of the second sleeve by the forming core; the diameter of the investment core is increased by setting the first sleeve on the investment core to ensure the product No manufacturing defects. The investment casting structure significantly improves production efficiency, improves product quality, and greatly reduces production costs.
