Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of aluminum alloy casting, especially relates to an aluminum alloy metal mold runner structure with cylindrical filter screen. BACKGROUND

[0002] In the aluminum alloy casting process, the use of filter screen is crucial to improve the quality of castings. The traditional filter screen placement method has many problems, such as difficult and complex positioning of the filter screen, which often requires complex tooling fixtures, increasing production costs and operation difficulty; moreover, the traditional filter screen is used at a high position, and unstable phenomena caused by aluminum liquid impacting the filter screen often occur during casting, leading to unstable filling of the aluminum liquid; at the same time, since impurities in the aluminum liquid cannot be effectively filtered, the castings are prone to have a large amount of gas and slag, which seriously affects the internal quality of the castings and reduces the product qualification rate.

[0003] Therefore, there is an urgent need to design a new structure to solve the above problems. UTILITY MODEL CONTENT

[0004] UTILITY MODEL OBJECTIVE: In order to overcome the above shortcomings, the utility model aims to provide an aluminum alloy metal mold runner structure with a cylindrical filter screen, which simplifies the positioning process of the filter screen by using a plug rod to assist in installing the cylindrical filter screen, eliminates the need for complex tooling fixtures, and reduces production costs and operation difficulty; at the same time, effectively filters impurities in the aluminum liquid, making the filling of the aluminum liquid more stable and improving the quality of the castings.

[0005] TECHNICAL SOLUTION: In order to achieve the above objective, the utility model provides an aluminum alloy metal mold runner structure with a cylindrical filter screen, which includes a fixed mold, a movable mold, a filter screen, and a plug rod; the movable mold is arranged opposite to the fixed mold; the fixed mold is provided with a fixed mold runner; the movable mold is provided with a movable mold runner; the fixed mold runner and the movable mold runner form a casting runner when they are folded together; the filter screen is cylindrical and is arranged in the casting runner; the plug rod is arranged above the filter screen and is used to insert the filter screen into the casting runner. The cylindrical filter screen is inserted into the casting runner with the help of the plug rod, ensuring stable positioning of the filter screen in the casting runner and avoiding movement of the filter screen during casting.

[0006] Further, a first limiting piece is arranged in the middle of the fixed mold runner; a fixed mold backflow channel is arranged on the upper part of the fixed mold runner; the height of the side of the fixed mold backflow channel close to the fixed mold runner is lower; and a fixed mold opening is arranged on the lower part of the fixed mold runner. The first limiting piece provides positioning for the filter screen; the fixed mold backflow channel ensures complete casting while the inclined design ensures the quality of the casting; and the fixed mold opening provides guidance for the flow of the aluminum liquid.

[0007] Further, the second limiting piece is arranged in the middle of the movable mold runner; the movable mold backflow channel is arranged in the upper part of the movable mold runner; the height of the movable mold backflow channel near the movable mold runner is lower; and the movable mold opening is arranged in the lower part of the movable mold runner. The second limiting piece provides positioning for the filter screen; the movable mold backflow channel ensures complete casting, and the inclined design ensures the quality of casting; and the movable mold opening provides guidance for the flow of aluminum liquid.

[0008] Further, the first limiting piece and the second limiting piece are folded to form a limiting table for limiting the filter screen. The limiting table cooperates with the filter screen and the plug rod to ensure that the filter screen is placed accurately and stably.

[0009] Further, the fixed mold backflow channel and the movable mold backflow channel are folded to form an inclined backflow channel. The inclined design of the backflow channel prevents the aluminum liquid that has not been filtered from flowing into the casting forming area, thereby reducing the quality of the casting.

[0010] Further, the fixed mold opening and the movable mold opening are folded to form a casting opening.

[0011] Further, during casting, the aluminum liquid first passes through the cylindrical filter screen, and impurities are effectively filtered; the filtered aluminum liquid smoothly passes through the casting opening for casting, thereby ensuring the stability of the filling process, reducing the amount of gas and slag in the casting, and improving the internal quality of the casting.

[0012] Further, a plurality of filter openings are arranged between the end faces of the filter screen. The filter openings between the end faces of the filter screen ensure that impurities are fully filtered, reduce the amount of gas and slag in the aluminum liquid, and improve the quality of the casting.

[0013] Further, a handle is arranged at the upper end of the plug rod. The handle facilitates holding and facilitates the insertion of the filter screen into the casting runner.

[0014] The above technical solution can achieve the following beneficial effects:

[0015] 1. The aluminum alloy metal mold runner structure with a cylindrical filter screen simplifies the positioning process of the filter screen, does not require complex tool clamps, and reduces production costs and operation difficulty.

[0016] 2. The aluminum alloy metal mold runner structure with a cylindrical filter screen is installed at a suitable position in the mold runner, avoids the instability caused by the direct impact of aluminum liquid on the filter screen, and makes the filling of aluminum liquid more stable.

[0017] 3. The aluminum alloy metal mold runner structure with a cylindrical filter screen effectively filters impurities in the aluminum liquid, significantly reduces the amount of gas and slag in the casting, improves the internal quality of the casting, and improves the product qualification rate.
