Description

Technical Field

[0001] The utility model relates to the technical field of aluminum scraping spoons, in particular to a double-rod aluminum scraping spoon used for a liquid riser pipe of a low-pressure casting machine. Background Art

[0002] Low-pressure casting is a method in which liquid metal fills a mold cavity from bottom to top under pressure and solidifies under pressure. Because the pressure used is relatively low (usually 0.02-0.05 MPa), it is called low-pressure casting. A low-pressure casting machine is a common device for low-pressure casting of aluminum alloy wheels. It consists of a main machine, a hydraulic system, a molten pool holding furnace, a liquid level pressurizing device, an electrical control system, and a mold cooling system. The riser is one of the components of a low-pressure casting machine. The process flow of a low-pressure casting machine is as follows: the mold is placed above a sealed crucible, and the liquid level pressurizing device then pressurizes the liquid metal in the crucible, creating a low pressure on the surface of the molten metal, causing the liquid metal to rise through the riser to fill the mold and control solidification.

[0003] After the molten metal flows through the riser, some molten aluminum or residue will adhere to the inner wall of the riser. This residue will affect the quality of the next casting and needs to be removed. The traditional way to remove it is to scrape it with an aluminum scraper. The working end of the existing aluminum scraper is flat and can only scrape the molten aluminum back and forth or shovel off the residue downward. On the one hand, it cannot collect the residue, causing the scraped aluminum residue to fall directly into the molten metal, which is not conducive to casting; on the other hand, for residues that adhere tightly, this aluminum scraper is difficult to clean, is very laborious to use, and is extremely inconvenient to operate in a small pipe space. Utility Model Content

[0004] The purpose of the utility model is to provide a double-rod aluminum scraper for a low-pressure casting machine riser pipe, so as to solve the problems that the existing aluminum scraper has no function of collecting residues, is very laborious to use and is extremely inconvenient to operate in a small pipeline space.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A double-rod aluminum scraper for a low-pressure casting machine riser pipe includes a bottom scraper, a hand-held rod and a slag bucket. The two hand-held rods are hinged to the upper surface of the bottom scraper. The slag bucket surrounds the outer circumference of the bottom scraper, and a slag storage cavity is formed between the slag bucket and the bottom scraper.

[0007] A further technical solution is: a first stopper is provided on the hand-held rod close to the feeding end of the bottom scraper, and a second stopper adapted to the first stopper is provided on the upper surface of the bottom scraper.

[0008] A further technical solution is that the outer side of the feeding end of the bottom scraper is configured as an arc-shaped structure that is compatible with the riser pipe.

[0009] A further technical solution is that a sharp portion is provided on the outer side of the feeding end of the bottom scraper.

[0010] A further technical solution is that the tail end of the handheld rod is threadedly connected to an extension rod.

[0011] A further technical solution is that: the upper outer edge of the slag blocking bucket is provided with a plurality of serrations.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] The utility model proposes a double-rod aluminum scraper for a rising pipe of a low-pressure casting machine. The aluminum scraper is handled by two hand-held rods. Firstly, it is labor-saving to use with both hands; secondly, the inclination angle of the bottom scraper can be changed by the two hand-held rods to better adapt to the diameter of the rising pipe and the distribution of aluminum liquid and residue on the inner wall of the rising pipe. The operation is more convenient and the scraping effect is improved.

[0024] Example 1:

[0025] This embodiment Figure 1 and Figure 2 As shown, a double-rod aluminum scraper for a low-pressure casting machine riser pipe includes a bottom scraper 1, a hand-held rod 2 and a slag bucket 3. The two hand-held rods 2 are hinged to the upper surface of the bottom scraper 1, and the slag bucket 3 surrounds the outer periphery of the bottom scraper 1, and a slag storage cavity is formed between the slag bucket 3 and the bottom scraper 1.

[0026] Before entering the riser pipe 6, if the aperture of the riser pipe 6 itself is small or the diameter is small due to the influence of adhered residue, the height difference can be generated by offsetting the two hand-held rods 2 up and down, so that the bottom scraper 1 is tilted to facilitate entry into the riser pipe 6. When scraping the material, the inclined bottom scraper 1 is used to scrape the molten aluminum. When shoveling the slag, the inclination angle of the bottom scraper 1 is appropriately adjusted according to the distribution of the residue to find a more labor-saving angle, or the two hand-held rods 2 can be moved up and down, so that the bottom scraper 1 can swing up and down to scrape off the residue. In addition, the bottom scraper 1 is provided with a slag bucket 3, and a slag storage cavity is formed between the slag bucket 3 and the bottom scraper 1 for collecting residue.

[0027] Example 2:

[0028] Based on the above embodiments, this embodiment Figure 2 As shown, a first stopper 4 is provided on the hand-held rod 2 near the feeding end of the bottom scraper 1 , and a second stopper 5 adapted to the first stopper 4 is provided on the upper surface of the bottom scraper 1 .

[0029] The first stopper 4 and the second stopper 5 cooperate to prevent the bottom scraper 1 from tilting at an excessively large angle, which would cause the residue collected in the residue storage chamber to fall out.

[0030] Preferably, the outer side of the feeding end of the bottom scraper 1 is configured as an arc-shaped structure adapted to the riser pipe 6 .

[0031] The feeding end of the bottom scraper 1 is arc-shaped, which can better fit the inner circumference of the rising pipe 6.

[0032] Preferably, a sharp portion is provided on the outer side of the feeding end of the bottom scraper 1 .

[0033] The sharp portion can chisel away the residues that are tightly adhered to the inner wall of the riser pipe 6 .

[0034] Preferably, if Figure 3 As shown, the tail end of the hand-held rod 2 is threadedly connected to an extension rod 7.

[0035] An extension rod 7 is threadedly connected to the tail end of the hand-held rod 2, which is suitable for a longer riser tube 6.

[0036] Preferably, the upper outer edge of the slag blocking bucket 3 is provided with a plurality of serrations 8 .

[0037] When the residue adhered to the inner wall of the liquid rising pipe 6 passes by, the serrations 8 on the outer edge of the slag blocking bucket 3 can be used to gradually scrape off the residue over and over again. Moreover, the serrations 8 disperse the force, which saves effort.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
