The molten aluminum in the melting furnace is still mostly transferred manually using a crucible spoon for the subsequent die-casting or pouring operation. As a result, personal injury accidents caused by high-temperature molten aluminum are frequent, affecting casting efficiency. In addition, the frequent use of crucible spoons to transfer molten aluminum will expose it to many impurities, which will also affect the quality of the molten aluminum. Utility Model Content

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0030] like Figures 1 to 7 In the embodiment of the precision aluminum block casting equipment of the present invention shown, the precision aluminum block casting equipment includes a melting furnace 200, a casting feed assembly 100 provided on the melting furnace 200 for conveying molten aluminum, and other precision aluminum block casting equipment such as a die-casting machine or a pouring mold. The casting feed assembly 100 is used to convey molten aluminum from the melting furnace 200 to other precision aluminum block casting equipment such as a die-casting machine or a pouring mold in the same process, replacing the currently widespread manual transfer of molten aluminum using a crucible spoon. In this embodiment, the casting feed assembly 100 can be used not only in the melting furnace 200 that can melt molten aluminum, but also in a holding furnace that can keep molten aluminum warm, and of course, it can also be used in a holding melting furnace that can both melt and keep molten aluminum warm.

[0031] The casting feeding assembly 100 includes a feeding curved tube 1, a piston 2 and a bracket 3. The piston 2 is arranged in the feeding curved tube 1. The feeding curved tube 1 and the piston 2 cooperate to transfer the molten aluminum in the melting furnace 200. The bracket 3 is used to support the feeding curved tube 1 and the piston 2. The bracket 3 can be used to conveniently set the feeding curved tube 1 and the piston 2 at specific positions on the melting furnace 200 to ensure the functionality of both; the bracket 3 is fixedly connected to the melting furnace 200 and / or the bottom surface. In the figure, the bracket 3 is provided with a support leg fixedly connected to the bottom surface. Of course, it can also be set on a related clamp or support leg fixedly connected to the melting furnace 200.

[0032] The feeding curved tube 1 includes an integrated immersion tube 11 and a fixed tube 12. The feeding curved tube 1 is in the shape of a pipe, wherein the immersion tube 11 is the pipe head and the fixed tube 12 is the pipe handle; the immersion tube 11 is partially immersed in the furnace chamber of the smelting furnace 200, and the fixed tube 12 is fixedly connected to the bracket 3; a piston cavity 101 is vertically provided in the immersion tube 11, and a feeding channel 102 is connected to the bottom of the piston cavity 101. The feeding channel 102 extends from the bottom of the immersion tube 11 to the top of the inlet tube 11, and then extends to the tail end of the fixed tube 12; the side wall of the feeding curved tube 1 is also provided with a feeding port 103 that communicates with the piston cavity 101. The feeding port 103 is a through hole on the side wall of the feeding curved tube 1, and the top of the feeding port 103 is lower than The height of the molten aluminum liquid level, so the molten aluminum will fill a part of the piston cavity 101 and a part of the feeding channel 102 from the feed port 103; at this time, when the piston 2 slides downward in the piston cavity 101, the molten aluminum in the piston cavity 101 will be pressed toward the feeding channel 102 to complete the feeding; specifically, when the piston 2 starts to slide downward at the top of the piston cavity 101, until the piston 2 is at the lower side of the feed port 103, the end of the piston 2 contacts the molten aluminum liquid level in the piston cavity 101 and fully applies force to the molten aluminum liquid level. Therefore, the molten aluminum is discharged outward from the feeding channel 102 that is connected to the bottom of the piston cavity 101 until it is sent to the tail end of the fixed tube 12, and then sent to the die-casting machine or the casting mold.

[0033] In this embodiment, there is no restriction on the shapes of the radial cross-sections of the piston cavity 101 and the piston 2. As an example: if the radial cross-section of the piston cavity 101 is set to a circle, then the piston 2 is correspondingly set to a cylinder, and a piston ring can be provided on the piston 2 to increase the sealing between the piston 2 and the side wall of the piston cavity 101; if the radial cross-section of the piston cavity 101 is set to a rectangle or a similar rectangle (for example, a rectangle with rounded corners as shown in the figure), the amount of molten aluminum transported in a single piston stroke can be increased (compared to a circle).

[0034] The casting feeding assembly 100 in the precision aluminum block casting equipment of the present invention replaces the currently widespread method of manually using a crucible spoon to transfer molten aluminum. The method of using a feeding curved tube 1 immersed in the molten aluminum in conjunction with a piston 2 to transfer the molten aluminum can also reduce the probability of the molten aluminum contacting impurities during the transfer process, prevent personal injury accidents caused by high-temperature molten aluminum, and ensure the quality of the molten aluminum to a certain extent.

[0035] In one embodiment of the present application, preferably, an end cover 13 is fixedly provided on the top surface of the piston cavity 101, and the end cover 13 can be used to prevent the molten aluminum from being pushed out when the piston 2 slides upward; the end cover 13 can also be used to limit the sliding of the piston handle 21 at the top end of the piston 2 in the radial direction to prevent the piston 2 from radially offset; the top surface of the piston cavity 101 is also provided with a return port 104, and the return port 104 is set as a through hole on the side wall of the top end of the piston cavity 101, and the return port 104 connects the piston cavity 101 and the furnace cavity of the smelting furnace 200, and the return port 104 is opened on the side wall of the immersion tube 11 away from the fixed tube 12. When the piston 2 slides upward in the piston cavity 101 to the end cover 13, the molten aluminum at the upper end of the piston 2 will return to the cranial cavity through the return port 104.

[0036] In one embodiment of the present application, preferably, the end cover 13 is provided with a shielding edge block 131 outside the return port 104, and the end cover 13 body and the shielding edge block 131 together guide the molten aluminum back into the furnace chamber to prevent the molten aluminum from colliding with the end cover 13 when it flows back and causing splashing.

[0037] In one embodiment of the present application, preferably, the upper end surface of the piston 2 is tilted, with the tilted surface facing the return port 104 , which is more conducive to the reflux of molten aluminum.

[0038] In one embodiment of the present application, preferably, the bracket 3 includes a gantry 32, a telescopic cylinder 33 is fixedly provided on the top of the gantry, the output end of the telescopic cylinder 33 is fixedly connected to the piston handle 21, the piston handle 21 is fixedly connected to the piston 2, and the piston handle 21 is passed through the end cover 13.

[0039] In one embodiment of the present application, preferably, a fixing rod 321 is provided between the gantry 32 and the end cover 13, and the gantry 32 and the end cover 13 are fixedly connected by the fixing rod 321, so that the feeding curved pipe 1 will also be fixed by the gantry 32 and become more stable.

[0040] In one embodiment of the present application, preferably, the feed curved tube 1, the end cover 13, the piston 2, and the piston handle 21 are all made of refractory materials, such as heat-resistant alloys or heat-resistant ceramic materials.

[0041] In one embodiment of the present application, preferably, the diameter of the piston chamber 101 is greater than the diameter of the feed channel 102, so as to reduce the retention amount of molten aluminum in the feed channel 102 as much as possible and increase the amount of molten aluminum transported in a single piston stroke.

[0042] In one embodiment of the present application, preferably, the bracket 3 further includes a curved pipe bracket 31 , the top end of the curved pipe bracket 31 is configured as a clamp-type flange, and the fixed pipe 12 is passed through the clamp-type flange.

[0043] In one embodiment of the present application, preferably, a connecting flange 121 is provided at the tail end of the fixed tube 12 to connect to a pouring pipe, or to connect to a conduit that can provide molten aluminum to the die-casting machine.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
