Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting technology, and in particular to an aluminum alloy quantitative casting device. Background Technology

[0002] Aluminum alloys are alloys based on aluminum with the addition of certain amounts of other alloying elements, and are one of the light metal materials. Aluminum alloys have good casting and plastic processing properties, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials. They have wide applications in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily consumer goods.

[0003] The casting process for aluminum alloy products is usually as follows: first, the aluminum alloy block is melted into molten aluminum, then the molten aluminum is poured from the distribution container into the mold cavity, and after the molten aluminum cools and solidifies, it is taken out of the mold. Finally, the product is completed through subsequent processes such as polishing. During the process of molten aluminum being poured into the distribution container through the slot, the liquid level in the distribution container will change continuously, which will directly affect the stability of the flow rate of the molten aluminum during pouring. If the flow rate of the molten aluminum is too fast or too slow, it will cause a large change in the pouring volume, resulting in the phenomenon of "too much material" or "too little material" in the casting. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where unstable aluminum molten flow rate during pouring leads to significant variations in pouring volume, affecting the quality of castings. Therefore, this invention proposes a quantitative pouring device for aluminum alloys.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design an aluminum alloy quantitative casting device, including a base, a support frame fixedly installed on the upper surface of the base, a storage box rotatably installed on the upper end of the support frame, a first electric heating jacket fixedly installed on the outer surface of the storage box, a casting nozzle fixedly installed on one side of the storage box, a ceramic filter screen fixedly installed inside the casting nozzle, a first electric telescopic cylinder fixedly installed on the upper surface of the base, a slider rotatably connected to the upper end of the first electric telescopic cylinder, a sliding seat fixedly installed at the bottom of the storage box, and the end of the slider slidably connected to the sliding seat.

[0006] Preferably, a second electric heating sleeve is fixedly installed on the outer surface of the pouring nozzle.

[0007] Preferably, the central axis of the first electric telescopic cylinder is parallel to the central axis of the storage box, and both are vertically arranged.

[0008] Preferably, a mounting bracket is also fixedly installed on the upper surface of the base, and a scraping mechanism is fixedly installed on the upper end of the mounting bracket.

[0009] Preferably, the scraping mechanism includes a second electric telescopic cylinder, a connecting frame is fixedly installed at the lower end of the second electric telescopic cylinder, a scraper is fixedly installed on one side of the connecting frame, a connecting rod is fixedly installed on the lower surface of the connecting frame, and a scraper disc is fixedly installed at the lower end of the connecting rod.

[0010] Preferably, the scraper is located directly above the pouring nozzle and is adapted to the shape of the inner side of the pouring nozzle.

[0011] Preferably, the scraper and the connecting frame have the same diameter and are both adapted to the inner side of the storage box, and the scraper and the connecting frame are parallel.

[0012] Preferably, the central axes of the storage bin, the second electric telescopic cylinder, the connecting frame, and the scraper are coincident.

[0013] The present invention provides an aluminum alloy quantitative and pouring device with the following advantages: During operation, the device heats the storage tank and the inside of the pouring nozzle using a first and second electric heating jacket, maintaining the internal temperature of the molten aluminum within a suitable range to prevent solidification and oxidation. A first electric telescopic cylinder tilts the storage tank, allowing the molten aluminum to be poured into the external cavity through the pouring nozzle. The stepped pouring method improves the stability of the pouring process. Furthermore, the horn-shaped pouring nozzle reduces the impact velocity of the molten aluminum, further stabilizing the pouring volume and achieving quantitative pouring. A ceramic filter screen prevents the removal of oxide slag from the molten aluminum. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1: Refer to Figure 1-3 A quantitative casting device for aluminum alloy includes a base 1, a support frame 3 fixedly installed on the upper surface of the base 1, a storage box 4 rotatably installed on the upper end of the support frame 3, the storage box 4 is used to store molten aluminum, and a first electric heating sleeve 9 is fixedly installed on the outer surface of the storage box 4. The first electric heating sleeve 9 can heat the side wall of the storage box 4, thereby maintaining a suitable temperature inside the storage box 4 and keeping the temperature of the molten aluminum within a suitable range, avoiding the problems of surface oxidation and decreased fluidity caused by the drop in temperature of the discharged molten aluminum.

[0018] A pouring nozzle 7 is fixedly installed on one side of the storage tank 4. The pouring nozzle 7 is funnel-shaped, which can reduce the impact speed during the pouring of molten aluminum and act as a buffer. A ceramic filter screen 8 is fixedly installed inside the pouring nozzle 7, which can mechanically intercept oxide slag mixed in with the molten aluminum. A second electric heating jacket 10 is fixedly installed on the outer surface of the pouring nozzle 7. The second electric heating jacket 10 can heat the side wall of the pouring nozzle 7, so that the pouring nozzle 7 can keep the molten aluminum heated during the pouring process, so that the molten aluminum can maintain a suitable temperature range and not solidify when passing through the pouring nozzle 7.

[0019] A first electric telescopic cylinder 6 is also fixedly installed on the upper surface of the base 1. The central axis of the first electric telescopic cylinder 6 is parallel to the central axis of the storage box 4 and both are vertically set. The upper end of the first electric telescopic cylinder 6 is rotatably connected to a slider 5. The bottom of the storage box 4 is fixedly installed with a slide block 16. The end of the slider 5 is slidably connected to the slide block 16. When the first electric telescopic cylinder 6 is started, it can drive the slider 5 to move upward. The slider 5 can slide in the slide block 16, and the slider 5 will drive the storage box 4 to move upward on this side through the slide block 16. Then the storage box 4 will tilt and pour out the aluminum liquid.

[0020] The first electric telescopic cylinder 6 tilts the storage tank 4 to pour out the molten aluminum. However, besides the tilt angle of the storage tank 4, the flow rate of the molten aluminum at the pouring nozzle 7 is also affected by changes in the molten aluminum level inside the storage tank 4. For example, when the storage tank 4 is at the same tilt angle, the molten aluminum level is high at the beginning of pouring, resulting in a faster flow rate and a larger pouring volume; conversely, the molten aluminum level is low at the end of pouring, resulting in a slower flow rate and a smaller pouring volume. Therefore, a "stepped pouring" method (controlling the angle in 2-3 stages) should be adopted according to the specific situation. Initially, the pouring is done at a small angle and low speed; in the middle stage, the angle is increased to accelerate the pouring; and finally, the angle is decreased to finish the pouring. This avoids sudden changes in flow rate, maintains a stable pouring volume, and achieves quantitative pouring.

[0021] Working principle: When the aluminum alloy quantitative casting device is working, the first electric heating jacket 9 heats the inside of the storage tank 4, and the second electric heating jacket 10 heats the inside of the casting nozzle 7, keeping the internal temperature of the aluminum liquid within a suitable range to prevent solidification and oxidation. The first electric telescopic cylinder 6 is activated to move the slider 5, which pushes the slide block 16 upward, thereby tilting the storage tank 4. The aluminum liquid is poured into the external cavity through the casting nozzle 7. According to the stepped segmented casting, the amount of aluminum liquid poured can be kept stable, realizing quantitative casting. The ceramic filter screen 8 can block the oxide slag inside the aluminum liquid.

[0022] Example 2: In Example 1, solidified aluminum alloy residue easily remains on the inner wall surface of the pouring nozzle 7, which affects the stability of the aluminum liquid flow rate during the next pour. Therefore, this example is proposed. (Refer to...) Figure 1-2 As another preferred embodiment of this utility model, based on embodiment 1, a mounting frame 2 is also fixedly installed on the upper surface of the base 1. A scraping mechanism is fixedly installed on the upper end of the mounting frame 2. The scraping mechanism includes a second electric telescopic cylinder 11. A connecting frame 12 is fixedly installed on the lower end of the second electric telescopic cylinder 11. A scraper 13 is fixedly installed on one side of the connecting frame 12. The scraper 13 is located directly above the pouring nozzle 7 and is adapted to the shape of the inner side of the pouring nozzle 7. When the scraper 13 moves downward, it can enter the pouring nozzle 7. The outer edge of the scraper 13 can be used to clean the residue adhering to the side wall of the pouring nozzle 7. A connecting rod 14 is fixedly installed on the lower surface of the connecting frame 12. A scraper 15 is fixedly installed at the lower end of the connecting rod 14. The scraper 15 has the same diameter as the connecting frame 12 and is adapted to the inner side of the storage box 4. The scraper 15 is parallel to the connecting frame 12. The central axes of the storage box 4, the second electric telescopic cylinder 11, the connecting frame 12, and the scraper 15 coincide. When the scraper 15 moves downward, it can enter the storage box 4. The outer edge of the scraper 15 can be used to clean the residue adhering to the side wall of the storage box 4. Timely cleaning of the residue on the inner wall of the storage box 4 and the pouring nozzle 7 can keep the inside of the storage box 4 and the pouring nozzle 7 smooth, which can make the subsequent aluminum liquid pouring smoother and more stable.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
