Description

Technical Field

[0001] This utility model relates to the field of casting equipment, and in particular to a liquid conversion structure and a low-pressure casting equipment having the same. Background Technology

[0002] The existing casting equipment is connected to a crucible furnace, whose lid has a gating gate through which molten aluminum flows into the casting equipment. Currently, the molten aluminum can only flow straight in and out. When the casting equipment needs to produce large castings, the molten aluminum can only flow into the casting equipment from the corresponding position in the middle of the casting. In other words, the existing gating gate cannot cover the entire casting, and the distance the molten aluminum travels from the middle to the edge of the casting is relatively long, resulting in excessive heat dissipation. However, the existing crucible furnace is commonly used equipment and is difficult to modify. Therefore, a structure is needed that, when installed in the crucible furnace, allows the gating gate to cover the entire casting. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a liquid-lifting conversion structure and a low-pressure casting device having the same.

[0004] The first aspect of the present invention provides a liquid-lifting conversion structure, which includes a liquid-lifting transition box. The liquid-lifting transition box has a channel assembly inside. The bottom of the liquid-lifting transition box has a liquid inlet communicating with the crucible furnace. The top of the liquid-lifting transition box has multiple liquid outlets communicating with the casting machine. Both the liquid inlet and the liquid outlets are communicating with the channel assembly.

[0005] Furthermore, the liquid inlet is configured to be multiple, and the channel assembly includes multiple liquid flow channels, each of which is connected to several liquid inlets and several liquid outlets.

[0006] Furthermore, the inner wall of the liquid flow channel has a heat-insulating coating.

[0007] Furthermore, the bottom surface of the liquid flow channel located on one side of the liquid inlet is inclined, with the end of the bottom surface closer to the liquid inlet being the lower end and the other end of the bottom surface farther from the liquid inlet being the higher end.

[0008] Furthermore, the liquid transfer tank includes a base and a plurality of covers detachably mounted on the base. Several liquid flow channels are formed between the base and each cover. The liquid inlet is located at the bottom of the base, and each cover is provided with several liquid outlets.

[0009] Furthermore, the cover is mounted to the top of the base by screws.

[0010] Furthermore, the plurality of liquid inlets are located in the middle of the bottom of the liquid transfer tank.

[0011] Furthermore, the bottom of the liquid transfer tank has multiple grooves, which are located on one side of the liquid inlet.

[0012] Furthermore, one portion of the liquid outlet is located in the middle of the liquid transfer tank, while the other portion of the liquid outlet is located at the edge of the liquid transfer tank.

[0013] The liquid-lift conversion structure of this utility model has at least the following technical effects:

[0014] 1. By setting up a liquid riser transition box between the crucible furnace and the casting machine, and the multiple liquid outlets of the liquid riser transition box can be distributed in the middle and far from the middle of the liquid riser transition box, the aluminum liquid discharged from the crucible furnace can flow to the middle and far from the middle of the liquid riser transition box. Thus, without modifying the crucible furnace, the aluminum liquid is guided to the middle and edge of the casting, so that the gate covers the entire casting. This is equivalent to guiding the aluminum liquid to the middle and edge of the casting through the channel assembly inside the liquid riser transition box.

[0015] 2. The inner wall of the liquid flow channel has a heat insulation coating to prevent the aluminum liquid temperature from dropping too quickly and to ensure the filling temperature of the aluminum liquid.

[0016] The low-pressure casting equipment of the second aspect of this utility model includes a liquid-lifting transition structure, a casting machine, and a crucible furnace as described in the first aspect. The casting machine includes a mold and a base plate. The liquid-lifting transition box is located on the top of the base plate. The mold is located on the top of the liquid-lifting transition box. The liquid outlet communicates with the cavity inside the mold. The top of the crucible furnace has a furnace cover. The furnace cover has a gating gate, and the gating gate communicates with the liquid inlet.

[0017] The low-pressure casting equipment according to this utility model has at least the following technical effects:

[0018] 1. The low-pressure casting equipment, by being equipped with the liquid-lifting conversion structure of the first aspect embodiment, can guide the aluminum liquid to the middle and edge of the casting without modifying the crucible furnace, so that the gate covers the entire casting.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figure 1 , 2 As shown in Figure 3, the liquid-lifting conversion structure of the first aspect embodiment of this utility model includes a liquid-lifting transition box 300. The liquid-lifting conversion structure is used to communicate with the crucible furnace 100 and the casting machine 200. The liquid-lifting conversion structure includes a liquid-lifting transition box 300, which has a channel assembly 310 inside. The bottom of the liquid-lifting transition box 300 has a liquid inlet 320 communicating with the crucible furnace 100, and the top of the liquid-lifting transition box 300 has multiple liquid outlets 330 communicating with the casting machine 200. Both the liquid inlet 320 and the liquid outlets 330 are connected to the channel assembly 310.

[0034] By providing a liquid riser transition box 300 between the crucible furnace 100 and the casting machine 200, and by distributing multiple liquid outlets 330 of the liquid riser transition box 300 in the middle and away from the middle, the aluminum liquid discharged from the crucible furnace 100 can flow to the middle and away from the middle of the liquid riser transition box 300. This allows the aluminum liquid to be guided to the middle and edge of the casting without modifying the crucible furnace 100, so that the gate 111 covers the entire casting. This is equivalent to guiding the aluminum liquid to the middle and edge of the casting through the channel assembly 310 inside the liquid riser transition box 300.

[0035] It is conceivable that the position of the liquid outlet 330 can be designed according to the size of the casting. For example, the liquid outlet 330 can be located in the middle of the liquid transfer tank 300, at the edge of the liquid transfer tank 300, or at both the middle and the edge of the liquid transfer tank 300.

[0036] Furthermore, such as Figure 3 , 4As shown in Figure 5, there are multiple liquid inlets 320 and multiple liquid flow channels 311 in the channel assembly 310. Each liquid flow channel 311 is connected to several liquid inlets 320 and several liquid outlets 330 to divide the channel assembly 310 into multiple liquid flow channels 311 and reduce the amount of aluminum liquid used.

[0037] For example, such as Figure 5 As shown, the liquid flow channel 311 at point C is connected to one inlet 320 and three outlets 330 (e.g., ...). Figure 4 As shown, β indicates the three liquid outlets 330.

[0038] Furthermore, the inner wall of the liquid flow channel 311 has a heat-insulating coating (not shown in the figure) to prevent the aluminum liquid temperature from dropping too quickly and to ensure the filling temperature of the aluminum liquid.

[0039] Specifically, the heat insulation coating uses heat-insulating fiber ceramic material, which can withstand high-temperature aluminum liquid temperatures above 730°C and can withstand filling pressures above 500 mbar.

[0040] Furthermore, such as Figure 3 As shown, the bottom surface of the liquid flow channel 311 located on one side of the liquid inlet 320 is inclined. The end of the bottom surface closer to the liquid inlet 320 is the low end, and the other end of the bottom surface away from the liquid inlet 320 is the high end. The bottom surface is inclined to ensure that the aluminum liquid can flow back into the crucible furnace 100 by its own gravity after filling.

[0041] Specifically, such as Figure 3 As shown, some of the liquid flow channels 311 have an inclined bottom surface, with the inlet 320 located at the lower end of the bottom surface; other liquid flow channels 311 have an upward protrusion 301 in the middle of the bottom, with the inlet 320 located on one side of the protrusion 301.

[0042] Furthermore, such as Figure 4 As shown, the liquid transfer tank 300 includes a base 340 and a plurality of covers 350 detachably mounted on the base 340. Several liquid flow channels 311 are formed between the base 340 and each cover 350. The liquid inlet 320 is located at the bottom of the base 340, and each cover 350 is provided with several liquid outlets 330.

[0043] Multiple covers 350 are detachably mounted on the base 340, and the covers 350 can be removed so that maintenance personnel can repair the heat insulation coating in the liquid flow channel 311; and having multiple covers 350 allows the liquid transfer tank 300 to be divided into sections, so that even if the heat insulation coating in one section is worn or damaged, we only need to treat and maintain the coating of that section, without having to replace the heat insulation coating of the entire tank, which facilitates subsequent maintenance.

[0044] Furthermore, the cover 350 is mounted on the top of the base 340 with screws, making it easy to install and remove the cover 350.

[0045] Furthermore, such as Figure 7 As shown, multiple liquid inlets 320 are located in the middle of the bottom of the liquid transfer tank 300, which facilitates communication with the gating port 111 of the crucible furnace 100.

[0046] Furthermore, such as Figure 7 As shown, the bottom of the liquid transfer tank 300 has multiple grooves 360, which are located on one side of the liquid inlet 320. These grooves can enhance the heat preservation capacity of the entire liquid transfer tank, allowing the aluminum liquid to maintain a certain temperature.

[0047] Furthermore, one part of the liquid outlet 330 is located in the middle of the liquid transfer tank 300, and the other part of the liquid outlet 330 is located at the edge of the liquid transfer tank 300, so that the aluminum liquid can flow to the middle and the edge of the casting.

[0048] like Figure 1 , 3 As shown, the low-pressure casting equipment of the second aspect of this utility model includes the liquid transfer structure of the first aspect embodiment, the casting machine 200 and the crucible furnace 100. The casting machine 200 includes a mold 210 and a base plate 220. The liquid transfer box 300 is disposed on the top of the base plate 220. The mold 210 is disposed on the top of the liquid transfer box 300. The liquid outlet 330 is connected to the cavity inside the mold 210. The top of the crucible furnace 100 has a furnace cover 110. The furnace cover 110 has a gate 111, which is connected to the liquid inlet 320.

[0049] The low-pressure casting equipment is equipped with a liquid transfer structure, which allows the molten aluminum to be guided to the middle and edge of the casting without modifying the crucible furnace 100, so that the gate 111 covers the entire casting.

[0050] During operation, the crucible furnace 100 pumps the molten aluminum inside to the gate 111 through pipes and pumps. The molten aluminum enters the liquid flow channel 311 through the gate 111 and the inlet 320, and then enters the cavity inside the mold 210 from the outlet 330.

[0051] Although the technical solutions of this utility model have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these technical solutions without departing from the principles and spirit of this utility model, the scope of which is defined by the claims and their equivalents.
