[0002] Currently, when producing aluminum alloy as-cast samples, due to the small production quantity, they are often produced by manual casting. However, the mechanical properties of aluminum alloy as-cast samples are greatly affected by factors such as the temperature, speed, and stability of manual casting, resulting in unstable mechanical properties and large deviations. This affects the accuracy of material research and development (or final product) testing, the determination of material properties, a large amount of experimental waste, a significant amount of production time, and reduced production efficiency. Summary of the Invention

The liquid outlet pipe has one end located at the bottom of the liquid storage container and the other end as the outlet. A solenoid valve, installed on the outlet pipe, is used to control the discharge of casting liquid. Both the liquid level sensor and the temperature sensor are installed inside the liquid storage container. The controller, the solenoid valve, the liquid level sensor and the temperature sensor are all connected to the controller via circuitry.

[0005] As a further technical solution, it also includes, A mold pushing device is disposed below the liquid outlet pipe. The mold pushing device is used to push the mold closer to or away from the outlet end of the liquid outlet pipe. When the mold is located close to the outlet end of the liquid outlet pipe, the mold inlet is connected to the liquid outlet pipe. A drain tank is movably positioned below the outlet pipe. After being moved, the drain tank approaches or moves away from the outlet end of the outlet pipe. When the drain tank is located near the outlet end of the outlet pipe, the drain tank is connected to the outlet pipe.

[0006] As a further technical solution, it also includes, The position sensor is installed on both the mold pushing device and the liquid discharge tank, and the position sensor is connected to the controller through a circuit.

[0007] As a further technical solution, it also includes, An alarm is connected to the controller via a circuit. The alarm will sound when the temperature and level of the casting liquid in the storage container do not meet the set values.

[0008] As a further technical solution, the mold pushing device includes, A first slider is slidably disposed below the liquid outlet pipe, and the first slider is used to place the mold. A first telescopic component is disposed on one side of the first slider. The telescopic rod of the first telescopic component is connected to the first slider. After the telescopic rod of the first telescopic component extends or retracts, the first slider slides towards or away from the liquid outlet pipe. The first telescopic component is connected to the controller via a circuit.

[0009] As a further technical solution, it also includes, A baking and drying device is disposed above the drain tank, and the baking and drying device is used to bake and dry the drain tank.

[0010] As a further technical solution, it also includes, A connecting pipe, one end of which is used to be installed at the inlet of the mold. A first housing has a first opening and a second opening that are opposite to each other. The first housing is disposed at the other end of the connecting pipe, and the first opening communicates with the connecting pipe. The second housing is rotatably disposed within the first housing. The second housing has a first through hole and a second through hole that are oppositely opened. After the second housing is rotated, the first through hole communicates with the first opening, and the second through hole communicates with the opening end of the liquid outlet pipe. When the first slider moves closer to the outlet pipe, one side of the outlet end of the outlet pipe contacts one side of the wall of the second through hole, causing the second housing to rotate. After the second housing rotates, the outlet end of the outlet pipe extends into the second through hole. The diameter of the second through hole is larger than the diameter of the liquid outlet pipe.

[0011] As a further technical solution, it also includes, A counterweight block is disposed on the outer wall of the second housing, and the counterweight block is located on one side of the second through hole. After the second housing rotates, the counterweight block blocks one side or the other side of the end of the second opening.

[0012] As a further technical solution When the counterweight block blocks one side of the end of the second opening, the second through hole is located outside the first housing and is used to insert the liquid outlet pipe. When the counterweight block blocks the other side of the end of the second opening, both the second through hole and the first through hole are located inside the first housing.

[0013] As a further technical solution, it also includes, A drain tank pushing device is disposed on one side of the drain tank for pushing the drain tank to move. The drain tank pushing device includes... The second slider is slidably disposed below the outlet pipe, and the discharge tank is disposed on the second slider.

[0014] The working principle and beneficial effects of this invention are as follows: In this invention, the liquid storage container is generally a liquid storage crucible. The liquid storage container has an insulating outer layer to prevent heat loss. When filling the mold with casting liquid, the controller transmits the temperature information of the casting liquid in the liquid storage container through a temperature sensor. When the appropriate temperature is reached, the controller controls the solenoid valve to open. When the liquid level sensor detects that a certain amount of casting liquid has been discharged, the controller controls the solenoid valve to close, thus completing the purpose of pouring casting liquid into the mold. The liquid level sensor can determine the discharge volume of casting liquid through the liquid level difference and can also display the current liquid level of the casting liquid. Pouring is only allowed when the appropriate liquid level is met to prevent the situation where the amount of casting liquid is insufficient for one pour, in which case the casting liquid needs to be replenished. In addition, the controller can control the degree of opening of the solenoid valve and control the flow rate of the casting liquid to meet the casting requirements. Compared with manual operation, the casting is more stable and the temperature is easier to control, which improves the repeatability and consistency of the produced aluminum alloy as-cast samples, improves the accuracy of the results of subsequent inspection of aluminum alloy as-cast samples, and facilitates the study of the influence of casting liquid temperature and flow rate on the mechanical properties of aluminum alloy as-cast samples.

Detailed Implementation

[0017] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of the present invention. For those skilled in the art, they can be understood as further technical solutions without creative effort. In some drawings, components with the same structure or function are only schematically illustrated, or only one is marked. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0018] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] like Figure 1-20 As shown, this invention proposes an automatic casting machine for casting mechanical property samples of aluminum alloys, comprising: The liquid storage container 1 is used to store the casting liquid. One end of the liquid outlet pipe 11 is located at the bottom of the liquid storage container 1, and the other end is the outlet end. The solenoid valve 21 is located on the liquid outlet pipe 11 and is used to control the discharge of the casting liquid. The liquid level sensor 22 and the temperature sensor 23 are both located inside the liquid storage container 1. The solenoid valve 21, the liquid level sensor 22 and the temperature sensor 23 are all connected to the controller 3 through a circuit.

[0021] In this embodiment, the liquid storage container 1 is generally a liquid storage crucible. The liquid storage container 1 has an insulating outer layer to prevent heat loss. When filling the mold with casting liquid, the controller 3 transmits the temperature information of the casting liquid in the liquid storage container 1 through the temperature sensor 23. When the appropriate temperature is reached (and the casting liquid level is appropriate, and the temperature and position of the mold are correct), the controller 3 can receive the casting or draining command. The controller 3 controls the solenoid valve 21 to open. When the liquid level sensor 22 detects that a certain amount of casting liquid has been drained, the controller 3 controls the solenoid valve 21 to close, thus completing the purpose of pouring casting liquid into the mold. The liquid level sensor 22 can, on the one hand, detect the liquid level... The position difference determines the discharge volume of the casting liquid, and on the other hand, it can display the current level of the casting liquid. Casting is only allowed when the appropriate level is met, preventing the situation where the amount of casting liquid is insufficient for one casting, in which case the casting liquid needs to be replenished. In addition, the controller 3 can control the degree of opening of the solenoid valve 21, and can control the flow rate of the casting liquid to meet the casting requirements. Compared with manual operation, the casting is more stable and the temperature is easier to control, which improves the repeatability and consistency of the produced aluminum alloy as-cast samples, improves the accuracy of the results of the subsequent inspection of aluminum alloy as-cast samples, and also facilitates the study of the influence of casting liquid temperature and flow rate on the mechanical properties of aluminum alloy as-cast samples.

[0022] Furthermore, the mold pushing device 4 is located below the liquid outlet pipe 11. The mold pushing device 4 is used to push the mold closer to or away from the outlet end of the liquid outlet pipe 11. When the mold is located close to the outlet end of the liquid outlet pipe 11, the mold inlet is connected to the liquid outlet pipe 11. The drain tank 51 is moved and located below the liquid outlet pipe 11. After the drain tank 51 moves, it is closer to or away from the outlet end of the liquid outlet pipe 11. When the drain tank 51 is located close to the outlet end of the liquid outlet pipe 11, the drain tank 51 is connected to the liquid outlet pipe 11.

[0023] In this embodiment, as Figure 2As shown, under the action of the mold pushing device 4, the mold can be located below the outlet pipe 11 and connected to it, or it can be moved to one side to facilitate the discharge of casting liquid from the outlet pipe 11 into the discharge tank 51. When discharging casting liquid into the mold through the outlet pipe 11, the discharge tank 51 is first moved below the outlet end of the outlet pipe 11 to collect the casting liquid. After opening the solenoid valve 21 to discharge a certain amount of casting liquid to clean and preheat the outlet pipe 11, the solenoid valve 21 is closed. Then, the preheated mold is pushed below the outlet end of the outlet pipe 11 through the mold pushing device 4, the solenoid valve 21 is opened, and a certain amount of casting liquid is discharged into the mold to complete the casting. In this way, discharging a certain amount of casting liquid into the discharge tank 51 first can flush and preheat the outlet pipe 11, improve the temperature consistency of the casting liquid poured into the mold, improve the casting quality, and help improve the consistency of the aluminum alloy cast sample. The discharge tank 51 is an open tank, which will be fully baked and dried before collecting the casting liquid.

[0024] Furthermore, it also includes a position sensor 24. The mold pushing device 4 and the liquid discharge tank 51 are both equipped with position sensors 24, and the position sensors 24 are connected to the controller 3 through a circuit.

[0025] In this embodiment, the position sensor 24 is used to transmit the position information of the mold pushing device 4 and the drain tank 51 to the controller 3. The controller 3, as a further technical solution, discharges the casting liquid into the drain tank 51 at a certain flow rate. After casting is completed, when it is necessary to drain the casting liquid in the storage container 1, it is also necessary to control the solenoid valve 21 to open to a large flow rate to facilitate the rapid drainage of the casting liquid and make the discharge cleaner.

[0026] Furthermore, the alarm 25 is connected to the controller 3 via a circuit. When the temperature and level of the casting liquid in the storage container 1 do not meet the set values, the alarm 25 will sound an alarm or provide a notification.

[0027] In this embodiment, the alarm 25 is set to remind the operator to perform casting when the conditions are met, or to prompt the operator to perform the next operation. This improves the casting accuracy, reduces the difficulty of operation for the operator, and enhances the overall safety.

[0028] Furthermore, the mold pushing device 4 includes a first slider 41 slidably disposed below the liquid outlet pipe 11, the first slider 41 being used to place the mold, a first telescopic member 42 disposed on one side of the first slider 41, the telescopic rod of the first telescopic member 42 being connected to the first slider 41, and after the telescopic rod of the first telescopic member 42 extends or retracts, the first slider 41 slides toward or away from the liquid outlet pipe 11, and the first telescopic member 42 is connected to the controller 3 through a circuit.

[0029] In this embodiment, as Figure 2As shown, the controller 3 controls the extension and retraction of the first telescopic component 42, which pushes the first slider 41 to slide, thereby driving the mold to move. The first telescopic component 42 is an electric cylinder or a pneumatic cylinder.

[0030] Furthermore, the vibrator 61 is mounted on the first slider 41 and is close to the mold.

[0031] In this embodiment, as Figure 3 As shown, the vibrator 61 can vibrate the mold during demolding, making demolding easier and increasing the demolding rate.

[0032] Furthermore, one end of the connecting pipe 62 is used to be set at the entrance of the mold. The first housing 63 has a first opening 64 and a second opening 65 that are opened opposite each other. The first housing 63 is set at the other end of the connecting pipe 62. The first opening 64 is connected to the connecting pipe 62. The second housing 66 is rotatably set inside the first housing 63. The second housing 66 has a first through hole 67 and a second through hole 68 that are opened opposite each other. After the second housing 66 rotates, the first through hole 67 is connected to the first opening 64. The second through hole 68 is used to connect to the opening end of the liquid outlet pipe 11. When the first slider 41 moves towards the liquid outlet pipe 11, one side of the outlet end of the liquid outlet pipe 11 contacts one side of the hole wall of the second through hole 68 and drives the second housing 66 to rotate. After the second housing 66 rotates, the outlet end of the liquid outlet pipe 11 extends into the second through hole 68. The diameter of the second through hole 68 is larger than the diameter of the liquid outlet pipe 11.

[0033] In this embodiment, as Figure 8 , Figure 12 and Figure 16 as well as Figure 9 , Figure 13 and Figure 17 This refers to the rotation process of the second housing 66 when the first slider 41 pushes the mold to move, i.e., in its natural state, such as... Figure 9 The second through hole 68 on the second housing 66 faces the liquid outlet pipe 11. During the movement towards the liquid outlet pipe 11, as... Figure 13 One side wall of the outlet pipe 11 will contact one side wall of the second through hole 68, and continue to move closer to the outlet pipe 11, such as Figure 17 The liquid outlet pipe 11 drives the second housing 66 to rotate and insert into the second through hole 68. At this time, the first through hole 67 is connected to the first opening 64, which is very convenient and can also prevent the liquid from colliding with the mold inlet when the liquid outlet pipe 11 discharges the casting liquid, causing the casting liquid to splash. This achieves the function of stable discharge of casting liquid and improves safety. The diameter of the second through hole 68 is slightly larger than the diameter of the liquid outlet pipe 11, which will satisfy the requirement that the liquid outlet pipe 11 is inserted into the second housing 66 while it rotates. The first housing 63 and the second housing 66 are spherical. Because the inner cavity is large, it will further reduce the possibility of casting liquid splashing.

[0034] Furthermore, a counterweight block 69 is disposed on the outer wall of the second housing 66. The counterweight block 69 is located on one side of the second through hole 68. After the second housing 66 is rotated, the counterweight block 69 blocks one side or the other side of the end of the second opening 65.

[0035] In this embodiment, as Figure 9 As shown, the counterweight block 69 is located on one side of the second through hole 68. Due to its offset from the center of gravity, it will cause the second housing 66 to remain in the position as shown. Figure 9 In its natural state, when not in use for a long time, it can be manually switched to such a position. Figure 5 In the closed state, the opening of the mold can be sealed to prevent contaminants from entering, further improving the casting quality.

[0036] Furthermore, when the counterweight block 69 is blocked on one side of the end of the second opening 65, the second through hole 68 is located outside the first housing 63 for inserting the liquid outlet pipe 11. When the counterweight block 69 is blocked on the other side of the end of the second opening 65, both the second through hole 68 and the first through hole 67 are located inside the first housing 63.

[0037] In this embodiment, as Figure 5 and Figure 9 As shown, the second housing 66 is in different states when the counterweight block 69 is in different positions.

[0038] Furthermore, the drain tank pushing device 7 is disposed on one side of the drain tank 51 for pushing the drain tank 51 to move. The drain tank pushing device 7 includes a second slider 71 slidably disposed below the outlet pipe 11, the drain tank 51 disposed on the second slider 71, and a second telescopic member 72 disposed on one side of the second slider 71. The telescopic rod of the second telescopic member 72 is connected to the second slider 71. After the telescopic rod of the second telescopic member 72 extends or retracts, the second slider 71 slides towards or away from the outlet pipe 11. The second telescopic member 72 is connected to the controller 3 through a circuit.

[0039] In this embodiment, as Figure 2 As shown, the second telescopic component 72 is an electric cylinder or a pneumatic cylinder, which drives the second slider 71 to slide.

[0040] Furthermore, the plate 81 is located below the outlet pipe 11. The first slider 41 and the second slider 71 are slidably disposed on the plate 81. The ends of the first slider 41 and the second slider 71 that are close to each other are hook ends. The plate 81 has a groove 82. The hook member 83 is hinged in the middle and disposed in the groove 82. The hook member 83 has a first hook part 84 and a second hook part 85. The first hook part 84 and the second hook part 85 are respectively located on both sides of the hinge. After the first slider 41 slides towards the outlet pipe 11, the second hook part 85 is squeezed into the groove 82 by the first slider 41. The first hook part 84 extends out of the groove 82 and hooks the hook end of the first slider 41. After the second slider 71 slides towards the outlet pipe 11, the first hook part 84 is squeezed into the groove 82 by the second slider 71. The second hook part 85 extends out of the groove 82 and hooks the hook end of the second slider 71.

[0041] In this embodiment, as Figure 4 , Figure 16 and Figure 20 As shown, the first hooking part 84 of the hooking member 83 is used to hook the hooking end of the first slider 41, and the second hooking part 85 of the hooking member 83 is used to hook the hooking end of the second slider 71.

[0042] Furthermore, the first hook portion 84 and the second hook portion 85 each have a guide slope on the side that is far apart from each other, and a hook surface on the side that is close to each other.

[0043] In this embodiment, as Figure 16 As shown, when the first slider 41 moves toward the liquid outlet pipe 11, it first squeezes the guide slope, so that the second hook part 85 is squeezed into the groove 82. Correspondingly, the first hook part 84 extends out of the groove 82 to limit the hook end of the first slider 41. Through mechanical means, the stability of use is further improved.

[0044] Furthermore, it also includes a temperature measuring and cooling device 91, located on one side of the mold, used to measure the mold temperature and cool the mold. The temperature measuring and cooling device 91 includes a temperature sensor and a cooling fan 92.

[0045] In this embodiment, as Figure 1 As shown, one side of the mold has a temperature measuring and cooling device 91 to detect the temperature of the mold. Before formal casting, the mold needs to be preheated by pouring casting liquid into it. That is, the temperature of the mold is raised by pouring casting liquid. When the mold temperature reaches a suitable temperature or slightly higher than the suitable temperature for formal casting, the preheating casting stops. The temperature sensor is used to measure the temperature of the mold. When the measured temperature is higher than the suitable temperature for formal casting, the cooling fan 92 will start. When the temperature drops to the suitable temperature for formal casting, the cooling fan will turn off, and then formal casting can be carried out normally.

[0046] Furthermore, the baking and drying device 94 is disposed above the drain tank 51, and the baking and drying device 94 is used to bake and dry the drain tank 51.

[0047] In this embodiment, the baking and drying device 94 uses electric heating wire to bake and dry the drain tank 51, improving safety. In addition, a second cooling fan 95 is provided on one side of the baking and drying device 94, which can cool the drain tank 51 and also work with the baking and drying device 94 to better dry the drain tank 51.

[0048] A heating device is installed outside the liquid storage container 1. The heating device uses an electric heating wire, and the heating power is controlled by controlling the current. In this way, the heat exchange rate between the liquid storage container 1 and the outside can be controlled by controlling the power of the heating device. When the temperature of the casting liquid in the liquid storage container 1 reaches the appropriate casting temperature, the heating power of the heating device only needs to meet the heat dissipation rate of the casting liquid. This increases the time it takes for the casting liquid in the liquid storage container 1 to reach the appropriate temperature, which is convenient for subsequent operations.

[0049] like Figure 2 As shown, the liquid storage container 1 is mounted on the plate 81 via columnar support rods on both sides.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
