Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to an adaptive flow control structure for a multi-channel casting system. Background Technology

[0002] Casting is a method of pouring molten metal into a mold cavity that conforms to the shape of the part, and then allowing it to cool and solidify to obtain the part or blank. Existing gating systems generally consist of a pouring cup, sprue, runner, and ingate. However, some mass-produced parts require multi-channel gating systems. But existing multi-channel gating systems simply guide molten metal into a large number of molds through various runners. Due to the different positions of the molds, the lengths and locations of the runners used for pouring molten metal vary, causing different molds to fill with molten metal at different times. When some molds are filled first and others are not, molten metal continues to be poured into the entire multi-channel gating system. This results in the runners of the molds that are filled first being filled with molten metal, which cannot enter other molds. As a result, a large amount of molten metal remains in the multi-channel gating system after each pour, making it unusable. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an adaptive flow control structure for a multi-channel casting system, which solves the problem that a large amount of molten metal remains in the multi-channel casting system during each casting process and cannot be used properly, resulting in low utilization of the molten metal.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adaptive flow control structure for a multi-channel gating system, comprising a top-opening gating box, a sprue at the bottom of the gating box, a horizontal runner connected to the bottom of the sprue, horizontal branch runners connected to both sides of the horizontal runner, a first solenoid valve installed on the branch runner, a vertical runner at the end of the branch runner, a mold connected to the bottom of the vertical runner via a gating end, an armored thermocouple installed inside the bottom of the vertical runner, a drain pipe at the bottom of the vertical runner, a second solenoid valve installed on the drain pipe, and a control display screen on the horizontal runner.

[0005] Preferably, a sealed heating box is provided on the direct casting channel.

[0006] Preferably, the side wall of the heating box is provided with a heating resistance tube.

[0007] Preferably, the bottom of the vertical gating system is provided with an upwardly inclined threaded hole near the bottom end.

[0008] Preferably, the surface of the armored thermocouple is provided with an external thread that corresponds to and engages with the threaded hole.

[0009] Preferably, the detection end of the armored thermocouple is tilted upward at a 45-degree angle and is located at the center line of the vertical gating system.

[0010] Preferably, the end of the drain pipe is connected to a liquid storage box that is fixedly connected to the pouring end.

[0011] Preferably, the end of the drain pipe is connected to a hollow pipe.

[0012] This invention provides an adaptive flow control structure for a multi-channel casting system, which has the following features:

[0013] Beneficial effects:

[0014] 1. This utility model uses a sheathed thermocouple installed at the bottom of the vertical runner to monitor the temperature inside the vertical runner at all times. When the mold is full, when the molten metal reaches the sheathed thermocouple and the molten metal level is detected, the first solenoid valve is closed to prevent excess molten metal from entering the sprue and vertical runner, thus preventing a large amount of molten metal from remaining in the multi-channel gating system and improving the utilization efficiency of molten metal.

[0015] 2. When the first solenoid valve is closed, the second solenoid valve is opened to allow the molten metal in the vertical gating channel to be discharged, thus preventing the armored thermocouple from being immersed in the molten metal for a long time and causing sleeve corrosion.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an adaptive flow control structure for a multi-channel gating system, including a gating box 1 with a top opening. The gating box 1 can be supported and fixed by a bracket. A straight gating 2 is provided at the bottom of the gating box 1. A horizontal gating 5 is connected to the bottom of the straight gating 2. Horizontal branch gating 13 is connected to both sides of the horizontal gating 5. A first solenoid valve 7 is installed on the branch gating 13. A vertical gating 6 is provided at the end of the branch gating 13. The bottom end of the vertical gating 6 is connected to a mold 11 through a gating end 10. A sheathed thermocouple 8 is installed inside the bottom end of the vertical gating 6. A drain pipe 601 is provided at the bottom of the vertical gating 6. A second solenoid valve 12 is installed on the drain pipe 601. A control display screen 14 is provided on the horizontal gating 5.

[0024] In this embodiment, a sealed heating box 3 is provided on the sprue 2, and a heating resistance tube 4 is provided on the side wall of the heating box 3. With this configuration, the heating resistance tube 4 is used to heat the heating box 3, thereby heating the molten metal flowing into the heating box 3 and preventing the molten metal from cooling and clumping. As a preferred embodiment, the heating box 3 can be omitted, and the heating resistance tube 4 can be directly wound around the sprue 2 to heat the molten metal.

[0025] In this embodiment, an upwardly inclined threaded hole is provided at the bottom of the vertical gating 6 near the bottom end, and the surface of the armored thermocouple 8 is provided with an external thread that corresponds to and mates with the threaded hole. This arrangement allows for easy assembly and disassembly of the armored thermocouple 8 through the engagement of the threaded hole and the external thread of the armored thermocouple 8, facilitating subsequent maintenance and replacement of the armored thermocouple 8.

[0026] In this embodiment, the detection end of the armored thermocouple 8 is tilted upward at a 45-degree angle and located at the center line of the vertical runner 6. This configuration allows the armored thermocouple 8 to constantly monitor the temperature of the molten metal. When the temperature of the molten metal is low, it can be heated by the heating resistance tube 4. Since the molten metal has just been poured into the vertical runner 6, the temperature detected by the armored thermocouple 8 is relatively high. Furthermore, because the molten metal falls vertically within the vertical runner 6, it does not always completely submerge the armored thermocouple 8. Therefore, the detected temperature curve will fluctuate dramatically. When the mold 11 is full and the armored thermocouple 8 is immersed in the molten metal, the molten metal has cooled down for some time, resulting in a lower temperature. Due to complete immersion, the detected temperature curve will gradually decrease. By observing these two different numerical conditions, it can be determined that the molten metal has filled the mold 11.

[0027] In this embodiment, the end of the drain pipe 601 is connected to a liquid storage box 9 that is fixedly connected to the gate end 10. By setting the liquid storage box 9, the molten metal soaking the armored thermocouple 8 can be drained in a timely manner, avoiding the armored thermocouple 8 from being immersed in the molten metal for a long time and causing sleeve corrosion.

[0028] In a preferred embodiment, the end of the drain pipe 601 can also be directly connected to a hollow pipe. By setting a hollow pipe, the molten metal soaking the armored thermocouple 8 can be drained in a timely manner, avoiding the armored thermocouple 8 from being immersed in the molten metal for a long time and causing sleeve corrosion.

[0029] Working principle:

[0030] In practical use, molten metal is poured into the gating tank 1. The molten metal flows sequentially into the mold 11 through the sprue 2, horizontal gating 5, branch gating 13, and vertical gating 6. At the same time, the temperature of the molten metal is constantly monitored by the armored thermocouple 8. When the temperature of the molten metal is too low, it can be heated by the heating resistance tube 4. When some molds 11 are filled first, the armored thermocouple 8 will be immersed in the molten metal. At this time, the temperature of the molten metal will be lower, and due to complete immersion, the detected temperature curve will tend to decrease gradually. The first solenoid valve 7 is closed by controlling the display screen 14 to prevent excess molten metal from entering the sprue 2 and vertical gating 6, and to prevent a large amount of molten metal from remaining in the multi-channel gating system, thereby improving the utilization efficiency of the molten metal. When the first solenoid valve 7 is closed, the second solenoid valve 12 is opened to drain the molten metal in the vertical gating 6, preventing the armored thermocouple 8 from being immersed in the molten metal for a long time and causing sleeve corrosion.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
