Description

Technical Field

[0001] This utility model relates to a gating system used in the casting process of thin-walled aluminum alloy investment casting parts, and belongs to the technical field of casting gating systems. Background Technology

[0002] When casting thin-walled aluminum alloy investment casting parts, multi-point injection filling is required to ensure the forming quality of the thin-walled castings.

[0003] The prior art can be found in Chinese Patent Publication No. CN206316323U. Due to the long length of the pouring cup and the sprue, the position of the pouring cup is prone to instability and does not correspond to the sprue. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a gating system used in the casting process of aluminum alloy investment casting thin-walled parts.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a gating system for use in the casting of thin-walled aluminum alloy investment castings, comprising:

[0007] Vertically distributed straight gating channels;

[0008] The top of the sprue has a pouring cup;

[0009] The bottom of the straight pouring channel has a horizontal pouring channel, which is connected to a vertical column pouring channel. The column pouring channel and the straight pouring channel are vertically spaced apart.

[0010] The top of the column gating system is connected to the pouring cup via reinforced gating system B.

[0011] A filter screen is installed on the horizontal runner near the column runner; the top of the column runner is connected to a riser via a reinforced runner A. The risers are multiple and spaced apart.

[0012] The column gating system has a horizontal ingate on its side. The ingate consists of multiple spaced-apart ingates, and the column gating system connects to the aluminum alloy thin-walled component through these multiple spaced-apart ingates.

[0013] The top of the column gating system is higher than the rim of the gating cup; the reinforced gating system B is located at the rim of the gating cup and connects to the top of the column gating system.

[0014] The beneficial effects of this utility model are as follows: when pouring molten metal into the pouring cup, the pouring cup is connected to the top of the column pouring channel through the reinforced pouring channel B, which ensures that the position of the pouring cup is stable and corresponds to the sprue. This solves the problem that the long length of the sprue can easily lead to an unstable position of the pouring cup and its correspondence with the sprue. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model;

[0016] In the diagram: 1-Pour cup; 2-Straight runner; 3-Horizontal runner; 4-Filter screen; 5-Column runner; 6-Ingate; 7-Riser; 81-Reinforced runner A; 82-Reinforced runner B; 9-Aluminum alloy thin-walled part. Detailed Implementation

[0017] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0018] like Figure 1 As shown.

[0019] This application discloses a gating system used in the casting of thin-walled aluminum alloy investment castings, comprising:

[0020] The top is equipped with a sprue 2 with a pouring cup 1, and the sprue 2 is vertically distributed; the bottom of the sprue 2 is equipped with a horizontal sprue 3, and the horizontal sprue 3 is connected to a vertical column sprue 5, which is spaced apart from the sprue 2.

[0021] A filter screen 4 is provided on the horizontal runner 3 near the column runner 5; the top of the column runner 5 is connected to the riser 7 through the reinforcing runner A81. The risers 7 are multiple and spaced apart.

[0022] The top of the column gating 5 is connected to the pouring cup 1 via the reinforced gating sprue B82.

[0023] The column gating 5 has a horizontal ingate 6 on its side. There are multiple ingates 6 spaced apart. The column gating 5 injects liquid into the aluminum alloy thin-walled part 9 through the multiple spaced ingates 6.

[0024] Molten aluminum alloy is poured into the gating cup 1 and flows through the sprue 2 onto the runner 3. The filter screen 4 on the runner 3 filters the molten metal. Then, the molten metal flows through the sprue 5 and the ingate 6 to fill the aluminum alloy thin-walled part 9. When pouring the molten metal into the gating cup 1, the gating cup 1 is connected to the top of the sprue 5 by the reinforced runner B82, which ensures that the position of the gating cup 1 is stable and corresponds to the sprue 2. This solves the problem that the long sprue length can easily lead to an unstable position of the gating cup and its correspondence with the sprue.

[0025] The top of the column gating 5 is higher than the mouth of the pouring cup 1; the reinforced gating B82 is located at the mouth of the pouring cup 1 and connects to the top of the column gating 5, ensuring that the molten metal flows from the pouring cup 1 to the sprue 2 first, and preventing the molten metal from flowing from the pouring cup 1 to the reinforced gating B82 first; after the molten metal emerges from the riser 7, through the reinforced gating A81 and the reinforced gating B82, when casting is completed, the molten metal fills the pouring cup 1, the sprue 2, the horizontal gating 3, the column gating 5, the ingate 6, the aluminum alloy thin-walled part 9, the riser 7, the reinforced gating A81, and the reinforced gating B82 to form a stable whole, avoiding the tendency of local side tilting and cracking.
