Description

Technical Field

[0001] The present application belongs to the field of anti-gravity casting technology, and particularly refers to an anti-gravity casting system. Background Art

[0002] In the current application of anti-gravity casting technology, the working principle of the anti-gravity casting equipment is mainly to load the preheated casting liquid into the holding furnace, and then use the liquid riser connected to the holding furnace to pour the liquid into the mold through the action of the liquid pump to achieve filling. After the liquid solidifies, the casting process is completed.

[0003] As the liquid pump drives the liquid into the mold, it is necessary to pour the liquid in a fixed amount. Generally, the aforementioned counter-gravity casting equipment is also equipped with a fixed amount detection device to detect liquid flow signals, such as flow rate and time, and feed them back to the control terminal. The control terminal then adjusts the operating time of the liquid pump to ensure that the liquid pouring amount reaches the required value.

[0004] In practice, many factors influence the accuracy of quantitative pouring, with the holding furnace's liquid level having a significant impact. At varying liquid levels, the flow of the casting liquid, particularly the molten metal, within the pipes can be inconsistent, leading to unstable quantitative test results and making them difficult to control and adjust. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a counter-gravity casting system to solve the technical problem in the counter-gravity casting equipment of the prior art that the quantitative pouring accuracy is easily affected by the liquid level height in the insulation furnace, resulting in inconsistent liquid flow state in the pipeline and unstable quantitative detection results.

[0006] To achieve the above objectives, the technical solution adopted in this application is to provide an anti-gravity casting system, comprising:

[0007] A holding furnace for holding the liquid for casting;

[0008] a riser pipe connected to the holding furnace, the riser pipe being provided with a quantitative detection device and a first pump body, the quantitative detection device detecting the flow rate of liquid flowing through the riser pipe; the riser pipe having an input pipe section extending into the holding furnace, the input pipe section having an upwardly bent portion, an extended end of the bent portion extending beyond the liquid level in the holding furnace, such that a liquid inlet on the extended end is higher than the liquid level in the holding furnace;

[0009] A liquid extraction pipe is arranged on the insulation furnace and extends to the liquid in the insulation furnace; the liquid extraction pipe is provided with a driving device for driving the liquid to flow to the output end of the liquid extraction pipe, and the output end of the liquid extraction pipe extends to above the liquid inlet to replenish the liquid inlet pipe.

[0010] The counter-gravity casting system provided by this application has the following advantages: compared with the prior art, the internal structure of the holding furnace is improved. The riser pipe is equipped with a quantitative detection device and a first pump body. The first pump body pours the molten metal from the holding furnace into the mold through the riser pipe. The quantitative detection device detects the flow rate of the molten metal flowing through the riser pipe.

[0011] To ensure that the corresponding liquid levels for quantitative testing remain at the same height, the structure of the riser tube has been improved. Specifically, the inlet section of the riser tube has a bent portion that extends into the liquid and bends upward. The extended end of this bent portion extends above the liquid surface, so that the liquid inlet on the extended end is higher than the liquid level in the holding furnace. In this way, this liquid inlet serves as a quantitative detection device to detect the corresponding liquid level of the liquid flowing through the riser tube. Because the position of the liquid inlet is fixed, the corresponding liquid level heights for quantitative testing are all at the same height, ensuring that the flow state of the molten metal within the riser tube is consistent, stabilizing the quantitative detection results and thereby improving the accuracy of quantitative casting.

[0012] Based on the above, it is necessary to replenish the liquid in the riser tube to ensure continuous pouring. The holding furnace of this application also includes a liquid extraction pipe equipped with a drive device. The output end of the liquid extraction pipe extends above the aforementioned liquid inlet. When the drive device is activated, liquid in the holding furnace is drawn into the liquid extraction pipe and discharged to the output end, replenishing the liquid inlet.

[0013] Thus, in the anti-gravity casting system of the present application, the riser pipe inside the holding furnace is fixedly arranged to maintain a consistent liquid level corresponding to the quantitative detection, and the riser pipe is replenished with liquid in a timely manner through the liquid extraction pipe. This not only enables normal casting, but also improves the precision of quantitative casting, thereby improving casting efficiency.

[0014] The riser's inlet structure has been improved to create an upward-facing, flat opening, ensuring it is parallel to the liquid level within the holding furnace. This allows any overflowing liquid to naturally fall back into the original liquid within the holding furnace before being drawn back through the extraction tube. This ensures that the liquid level corresponding to the quantitative measurement is on a flat surface, serving as a reference for the measurement and facilitating subsequent parameter settings for the quantitative measurement device, ultimately improving measurement accuracy.

[0015] Optionally, the liquid inlet is a bell-shaped port, and the input pipe section between the liquid inlet and the bent portion is gradually narrowed. This increases the receiving space of the liquid inlet, allowing the liquid to fall accurately into the liquid inlet after being discharged from the output end of the liquid extraction tube, thereby effectively improving the accuracy of liquid delivery.

[0016] The riser tube structure is improved, with the section between the liquid inlet and the bend being an inclined section. This inclined section is preferably arranged to slope from the liquid inlet toward the bend. This allows the added liquid to flow naturally into the riser tube and, under the action of the first pump body, be smoothly poured into the mold.

[0017] Optionally, the bend on the input pipe section is an arc-shaped transition. On the one hand, within the pipe, this arc-shaped transition effectively ensures smooth internal liquid flow, avoiding narrow angles that could affect the natural flow of liquid; or, alternatively, preventing the formation of "slag collection" areas where molten metal easily solidifies and could cause pipe blockage. On the other hand, the arc-shaped transition also forms an arc section outside the pipe, effectively preventing the formation of "slag collection" areas that could cause blockage and ensure smooth liquid flow within the holding furnace cavity.

[0018] Optionally, the bend on the inlet pipe section is spaced apart from the inner bottom of the holding furnace. This allows the riser pipe to be spaced apart from the inner bottom of the holding furnace, at the lowest point within the holding furnace, i.e., the bottom of the bend. This prevents the bend from merging with the inner bottom of the holding furnace to form a blockage, thereby ensuring smooth flow of liquid within the holding furnace. Furthermore, the separation of the bend from the inner bottom prevents the riser pipe from connecting to the furnace bottom, effectively preventing external heat from directly transferring to the riser pipe and shortening its service life.

[0019] The structure of the liquid extraction tube has been improved. The tube is vertically installed within the holding furnace. The lower end of the tube can be inserted into the liquid within the holding furnace, and the output end extends laterally from one side of the tube to above the liquid inlet of the riser tube. The tube can be integrally formed within the holding furnace, which helps to strengthen the position of the tube. The output end of the tube is located above the liquid inlet, allowing the liquid output from the tube to accurately fall into the liquid inlet, effectively ensuring the accuracy of liquid transfer, allowing for continuous and smooth delivery of the entire pouring liquid, and thereby improving pouring efficiency.

[0020] The drive mechanism has been improved to include a second pump body. Both the second and first pump bodies are AC electromagnetic pumps, with the first pump body installed on the inlet section of the riser pipe. Taking advantage of the AC electromagnetic pump's compact size, it's easy to move and store. This eliminates the need for special modifications to the holding furnace, allowing both the first and second pump bodies to be installed inside the furnace, reducing modification costs.

[0021] Another improvement to the drive mechanism is a drive cylinder, located outside the holding furnace. Connected to the drive cylinder is a piston capable of displacement within the liquid extraction tube. This mechanism utilizes the drive cylinder, coupled to the piston, to pump liquid from the extraction tube and deliver it to the output end of the tube, thereby creating a vacuum and driving the liquid to the riser tube for replenishment, achieving the same technical effect.

[0022] The structure of the quantitative detection device is improved. The quantitative detection device is installed on the riser pipe section outside the holding furnace. In this way, the quantitative detection device is installed outside the holding furnace to reduce the impact of heat, effectively ensure the operational stability of the quantitative detection device, and extend its service life.

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0037] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0038] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0040] In related technologies, such as Figure 1 As shown (the black area in the figure indicates the liquid flowing within the equipment), the counter-gravity casting equipment includes a holding furnace A, a riser pipe B, and a pump C. Holding furnace A holds the casting liquid. One end of riser pipe B connects to holding furnace A, and the other end connects to the mold (not shown). During the counter-gravity casting process, the molten metal in holding furnace A, driven by pump C, is injected through riser pipe B into the mold, filling the mold cavity and eventually solidifying, completing the casting.

[0041] To quantitatively detect the liquid flow rate, the equipment is also equipped with a quantitative detection device D. However, as the liquid in the holding furnace is gradually pumped out by the pump, the liquid level L1 in the holding furnace gradually decreases. This change in liquid level L1 will also affect the liquid flow state in the riser pipe, resulting in unstable quantitative detection results.

[0042] In order to solve the above technical problems, the present invention provides a novel anti-gravity casting system, which is now described in detail. Figure 2 and Figure 3 ( Figure 2 The black surface in the figure represents liquid), and a counter-gravity casting system includes a holding furnace 1, a liquid riser 2, and a liquid extraction pipe 3.

[0043] The holding furnace 1 is filled with liquid for casting. In this embodiment, the liquid is metal liquid, mainly aluminum liquid.

[0044] One end of the riser pipe 2 is connected to the mold (not shown), and the other end is connected to the holding furnace 1. The riser pipe 2 is provided with a quantitative detection device 4 and a first pump body 5. The quantitative detection device 4 detects the flow rate of the liquid flowing through the riser pipe 2.

[0045] Please also refer to Figure 2 and Figure 3 The rising pipe 2 has an input pipe section 21 extending into the insulation furnace 1. The input pipe section 21 has a bent portion 22 extending into the liquid and bending upward. The extended end of the bent portion 22 extends out of the liquid level in the insulation furnace 1, so that the liquid inlet 23 on the extended end is higher than the liquid level height L1 in the insulation furnace 1.

[0046] The liquid extraction pipe 3 is mounted on the holding furnace 1 and extends to the liquid in the holding furnace 1. A driving device 6 is provided on the liquid extraction pipe 3 to drive the liquid to flow toward the output end 31 of the liquid extraction pipe 3. The output end 31 of the liquid extraction pipe 3 extends above the liquid inlet 23 to replenish the liquid in the riser pipe 2.

[0047] Compared to the prior art, the counter-gravity casting system provided in the present embodiment features an improved internal structure of the holding furnace 1. Riser pipe 2 is provided with a quantitative detection device 4 and a first pump body 5. The first pump body 5 pours the molten metal from the holding furnace 1 through the riser pipe 2 onto the mold. The quantitative detection device 4 detects the flow rate of the molten metal flowing through the riser pipe 2.

[0048] In order to keep the corresponding liquid levels of quantitative detection at the same height, the structure of the rising pipe 2 is improved. Figure 2 and Figure 3As shown, the inlet section 21 of the riser tube 2 has an upwardly curved portion 22 that extends into the liquid. The extended end of this curved portion 22 protrudes above the liquid surface, allowing a liquid inlet 23 on the extended end to be higher than the liquid level L1 within the holding furnace 1. This inlet 23 thus serves as a quantitative detection device 4 for detecting the corresponding liquid level L2 of the liquid flowing through the riser tube 2. Because the position of the liquid inlet 23 is fixed, the corresponding liquid level L2 for quantitative detection is always at the same height, ensuring consistent flow of the molten metal within the riser tube 2. This stabilizes the quantitative detection results and improves the accuracy of quantitative pouring.

[0049] On the basis of the above, it is necessary to replenish the liquid on the riser 2 so that the pouring can be carried out continuously. Figure 2 and Figure 3 As shown, the holding furnace 1 of the present application is further provided with a liquid extraction pipe 3, on which a driving device 6 is provided. An output end 31 of the liquid extraction pipe 3 extends above the liquid inlet 23. When the driving device 6 is activated, the liquid in the holding furnace 1 is drawn into the liquid extraction pipe 3 and discharged to the output end 31, and the liquid is replenished to the liquid inlet 23.

[0050] Thus, in the anti-gravity casting system of the present application, the riser pipe 2 is fixedly arranged inside the holding furnace 1, so that the liquid level corresponding to the quantitative detection remains consistent, and the riser pipe 2 is replenished with liquid in a timely manner through the liquid extraction pipe 3. This can not only achieve normal casting, but also improve the precision of quantitative casting, thereby improving casting efficiency.

[0051] In the related art, to replenish liquid in riser tube 2, a lifting mechanism (not shown) may be installed on riser tube 2, allowing the section of riser tube 2 located inside holding furnace 1 to extend and retract. This allows automatic replenishment of liquid in riser tube 2 while maintaining the same liquid level for each test, and eliminates the need for extraction tube 3. However, the addition of a lifting mechanism changes the shape of riser tube 2 and requires additional displacement and positioning, making modification difficult and costly. Furthermore, the driving components of the added lifting mechanism must meet high-temperature resistance and rigidity requirements; otherwise, they are susceptible to damage and have a short service life, further increasing the difficulty of modification.

[0052] In the anti-gravity casting system provided in the embodiment of the present application, the riser pipe 2 is fixedly arranged or preferably integrally formed on the holding furnace 1, so that the height of the liquid inlet 23 is fixed, the liquid level L2 corresponding to the quantitative detection remains unchanged, the quantitative detection structure is stable, and the quantitative casting accuracy is effectively improved. In addition, by adding a liquid extraction pipe 3 to replenish the liquid in the riser pipe 2, the liquid extraction pipe 3 is also fixedly arranged or preferably integrally formed on the holding furnace 1, and can realize the delivery of liquid to the liquid inlet 23 of the riser pipe 2. The structure of the liquid extraction pipe 3 is simple and easy to implement, effectively controlling the cost of modification.

[0053] In the embodiments of this application, please refer to Figure 3 and Figure 4 The liquid inlet 23 of the rising tube 2 is preferably an upward-facing flat opening, ensuring that the flat opening 23 is parallel to the liquid level within the holding furnace 1. This allows any overflowing liquid to naturally fall back into the original liquid within the holding furnace 1 and be circulated and extracted by the liquid extraction tube 3. This ensures that the liquid level L2 corresponding to the quantitative measurement is located on a flat surface, facilitating the subsequent parameter setting of the quantitative measurement device 4 to improve measurement accuracy.

[0054] Preferably, if Figure 4 As shown, the liquid inlet 23 of the riser tube 2 is a bell-shaped opening, and the input pipe section 21 between the liquid inlet 23 and the bend 22 is gradually narrowed. This increases the receiving space of the liquid inlet 23, allowing the liquid discharged from the output end 31 of the liquid extraction tube 3 to accurately fall into the liquid inlet 23, effectively improving the accuracy of liquid delivery.

[0055] In the embodiments of this application, please refer to Figure 3 and Figure 4 The section of the riser tube 2 between the liquid inlet 23 and the bend 22 is an inclined section 24. In this embodiment, this inclined section 24 is preferably arranged to be inclined from the liquid inlet 23 toward the bend 22. This allows the added liquid to flow naturally into the riser tube 2 and, under the action of the first pump body 5, be smoothly poured into the mold.

[0056] Among them, such as Figure 4 As shown, the bend 22 on the inlet pipe section 21 is preferably an arc-shaped transition.

[0057] On the one hand, for the interior of the pipeline, the arc-shaped transition bend 22 can effectively ensure the smooth flow of the internal liquid, avoid the existence of narrow angles that affect the natural flow of the liquid; or avoid the formation of "slag collection" areas after the metal liquid easily solidifies in these narrow angles, causing blockage of the pipeline.

[0058] On the other hand, the bend 22 forms an angled portion M outside the pipe. If this angled portion M is too small, liquid, particularly metal used in casting, could solidify and form "dross," creating a blockage that could hinder liquid flow. Therefore, the curved transition bend 22 also forms an arc segment outside the pipe, effectively preventing this area from forming a "dross" blockage and ensuring smooth liquid flow within the inner cavity of the holding furnace 1.

[0059] Preferably, if Figure 4As shown, the bend 22 on the inlet pipe section 21 of the riser pipe 2 is spaced apart from the inner bottom surface of the holding furnace 1, such that a distance X is provided between the bend 22 and the inner bottom surface of the holding furnace 1. Thus, the riser pipe 2 is spaced apart from the inner bottom surface of the holding furnace 1 at the lowest point inside the holding furnace 1, i.e., the bottom of the bend 22. This prevents the bend 22 from merging with the inner bottom surface of the holding furnace 1 to form a blockage, thereby ensuring smooth flow of liquid within the holding furnace 1.

[0060] In addition, the bent portion 22 is separated from the inner bottom surface of the insulation furnace 1, which can also prevent the riser pipe 2 from being connected to the inner bottom surface of the insulation furnace 1, and effectively avoid the heating device set outside the insulation furnace 1 from directly transferring the heat used to heat the insulation furnace 1 to the riser pipe 2, causing damage to the riser pipe 2 and shortening the service life of the riser pipe 2.

[0061] In the embodiments of this application, please refer to Figure 3 and Figure 5 The liquid extraction pipe 3 is vertically arranged in the holding furnace 1. The lower end of the liquid extraction pipe 3 can extend into the liquid in the holding furnace 1. The output end 31 extends horizontally from one side of the pipe body of the liquid extraction pipe 3 to above the liquid inlet 23 of the riser 2. The liquid extraction pipe 3 can be integrally formed in the holding furnace 1, which is conducive to strengthening the position fixation effect of the liquid extraction pipe 3. The output end 31 of the liquid extraction pipe 3 is located above the liquid inlet 23, so that the liquid output from the liquid extraction pipe 3 can accurately fall into the liquid inlet 23, effectively ensuring the accuracy of liquid transmission, making the entire casting liquid conveyance continuous and smooth, thereby improving casting efficiency.

[0062] In one embodiment of this application, please refer to Figure 3 and Figure 5 , the driving device 6 on the liquid extraction pipe 3 is a second pump body, and the second pump body and the first pump body 5 are both AC electromagnetic pumps, and the first pump body 5 is arranged on the input pipe section 21 of the liquid lifting pipe 2. For electromagnetic pumps used in anti-gravity casting equipment, DC electromagnetic pumps are large in size, so the DC electromagnetic pumps need to be arranged outside the insulation furnace 1, resulting in the insulation furnace 1 needing to be specially customized, increasing production costs. In the anti-gravity casting system of the present application, each pump body adopts an AC electromagnetic pump. The AC electromagnetic pump has a small size and is convenient for movement and storage. The insulation furnace 1 does not need special modification, so that the first pump body 5 and the second pump body can be arranged inside the insulation furnace 1, thereby reducing the modification cost.

[0063] In another embodiment of the present application (not shown), the driving device 6 on the liquid extraction pipe 3 is preferably a driving cylinder (not shown), which is disposed outside the holding furnace 1 and is connected to a piston (not shown) capable of displacement within the liquid extraction pipe 3. In this manner, the driving cylinder, connected to the piston, is used to draw liquid from the liquid extraction pipe 3 and deliver it to the output end 31 of the liquid extraction pipe 3 for output, thereby creating a vacuum and driving the liquid to replenish the liquid in the riser pipe 2, thereby achieving the same technical effect.

[0064] In the examples of this application, please refer to Figure 3 The quantitative detection device 4 is arranged on the riser pipe 2 outside the holding furnace 1. In this way, the quantitative detection device 4 is arranged outside the holding furnace 1 to reduce the influence of heat, effectively ensure the operation stability of the quantitative detection device 4, and extend its service life.

[0065] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
