[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides a zinc alloy casting guide device, including a guide pipe 1, which provides a conveying channel for liquid zinc alloy. One end of the guide pipe 1 is provided with a filter assembly 3. The filter assembly 3 prevents impurities from entering the mold through filtration, thus ensuring the quality of the casting. A first mounting flange 5 is fixedly connected to one side of the filter assembly 3, and a second mounting flange 4 is fixedly connected to one side of the guide pipe 1. The first mounting flange 5 facilitates the convenient connection and disassembly of the filter assembly 3 and the guide pipe 1, and also facilitates connection to the mold channel. The second mounting flange 4 facilitates connection to the output end of the liquid zinc alloy.

[0020] The first mounting flange 5 and the second mounting flange 4 each have a groove 7 on one side. A sealing gasket 6 is fixedly installed inside the groove 7. The sealing gasket 6 is inside the groove 7 to enhance the sealing of the flange connection and prevent leakage of liquid zinc alloy. The guide pipe 1 is equipped with a flow regulating component 2. The flow regulating component 2 can accurately regulate the flow rate of liquid zinc alloy in the guide pipe 1 and improve the casting quality.

[0021] The flow regulating component 2 includes a mounting box 28, which is fixedly installed on the outer surface of the guide pipe 1. A stepper motor 27 is fixedly installed inside the mounting box 28. The stepper motor 27 can precisely control the opening and closing degree of the ball valve 24 to achieve fine regulation of the liquid zinc alloy flow. A slot 22 is provided on one side of the mounting box 28. A cooling fan 23 for use with the stepper motor 27 is fixedly installed inside the slot 22. Heat dissipation holes 21 for use with the cooling fan 23 are symmetrically provided on both sides of the mounting box 28. The cooling fan 23 cooperates with the heat dissipation holes 21 to dissipate heat from the stepper motor 27 and ensure its stable operation.

[0022] Furthermore, a round rod 25 is fixedly connected to the output end of the stepper motor 27, and a seepage-proof gasket 26 for use with the round rod 25 is fixedly installed on the outer surface of the guide pipe 1. The round rod 25 and the seepage-proof gasket 26 are rotatably connected. The seepage-proof gasket 26 prevents liquid zinc alloy from leaking from the connection between the round rod 25 and the guide pipe 1, ensuring sealing. The bottom end of the round rod 25 passes through the guide pipe 1 and is fixedly connected to a ball valve 24. The ball valve 24 adjusts the flow rate of liquid zinc alloy in the guide pipe 1 under the action of the round rod 25.

[0023] The filter assembly 3 includes a filter screen 34, which is movably snapped onto one side of the guide pipe 1. The filter screen 34 intercepts impurities, and the movable snap-fit ​​facilitates cleaning and replacement. A positioning ring 31 is fixedly sleeved on the outer surface of the guide pipe 1. A clamping plate 32 that works with the filter screen 34 is movably snapped onto one side of the positioning ring 31. The positioning ring 31 and the clamping plate 32 position and fix the filter screen 34, ensuring filtration effect and ease of disassembly and assembly. The clamping part is equipped with a sealing structure to ensure its sealing during use. A positioning groove 36 that works with the filter screen 34 is opened on one side of the clamping plate 32. One side of the filter screen 34 is movably snapped into the positioning groove 36. The positioning groove 36 accurately positions the filter screen 34 to prevent it from shifting or loosening.

[0024] One side of the clamping plate 32 is fixedly connected to the first mounting flange 5. The clamping plate 32 and the positioning ring 31 are connected by a locking bolt 33. The positioning ring 31 has a first screw hole 35 arranged in a ring array on one side. The clamping plate 32 has a second screw hole 37 on one side. The locking bolt 33 is threadedly connected to the first screw hole 35 and the second screw hole 37. The locking bolt 33, by cooperating with the first screw hole 35 and the second screw hole 37, firmly fixes the filter screen 34 and facilitates disassembly.

[0025] Working principle: First, the second mounting flange 4 on one side of the guide pipe 1 and the first mounting flange 5 on the side of the filter assembly 3 are used to connect the device with other equipment or components. The sealing gasket 6 fills the gap when the flange is connected, which plays a sealing role, prevents the liquid zinc alloy from leaking, and ensures the safe and stable progress of the casting process.

[0026] After the liquid zinc alloy flows out from the casting source, it first passes through the filter component 3 at one end of the guide pipe 1, where impurities are intercepted by the filter screen 34, and then flows to the mold through the guide pipe 1. During this process, the flow regulating component 2 adjusts the flow rate of the liquid zinc alloy according to the casting requirements to ensure that it fills the mold cavity stably and evenly.

[0027] When it is necessary to adjust the flow rate of liquid zinc alloy, the stepper motor 27 is started through the flow adjustment component 2. When the stepper motor 27 rotates, it drives the round rod 25 fixedly connected to its output end to rotate. The round rod 25 passes through the guide tube 1 and drives the ball valve 24 at the bottom to rotate. By changing the opening and closing angle of the ball valve 24, the flow area of ​​liquid zinc alloy in the guide tube 1 is adjusted, thereby achieving precise control of the flow rate.

[0028] Meanwhile, the anti-seepage gasket 26 can prevent liquid zinc alloy from leaking from the connection between the round rod 25 and the guide pipe 1, ensuring sealing. In addition, the cooling fan 23, together with the heat dissipation holes 21 on both sides, dissipates heat for the stepper motor 27, ensuring its stable operation.

[0029] The filter screen 34 is movably snapped onto one side of the guide tube 1 via the filter assembly 3. The positioning ring 31 on the outer surface of the guide tube 1 cooperates with the pressure plate 32, and the positioning groove 36 on one side of the pressure plate 32 precisely positions the filter screen 34.

[0030] By passing the locking bolt 33 through the first screw hole 35 of the positioning ring 31 and the second screw hole 37 of the pressure plate 32, the pressure plate 32 is firmly connected to the positioning ring 31, thereby securing the filter screen 34.

[0031] When the liquid zinc alloy flows through, the filter screen 34 intercepts impurities to prevent them from entering the mold and affecting the quality of the casting. When the filter screen 34 needs to be cleaned or replaced, the locking bolt 33 can be unscrewed to remove the clamping plate 32 and easily take out the filter screen 34.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
