Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to an aluminum alloy casting equipment capable of reducing burrs on the surface of castings. Background Art

[0002] Aluminum alloy has good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials. It has a wide range of applications in aerospace, aviation, transportation, construction, electromechanics, light chemical industry and daily necessities. According to its composition and processing methods, it is divided into wrought aluminum alloy and casting aluminum alloy. Wrought aluminum alloy is first melted and cast into ingots, and then subjected to plastic deformation processing to make various plastic processing products through methods such as rolling, extrusion, stretching, forging, etc. Casting aluminum alloy is to melt the ingredients and then cast them into the blanks of various parts with casting equipment. Therefore, the Chinese authorized invention patent (publication number: CN116274976B) proposes an aluminum alloy casting equipment capable of reducing burrs on the surface of castings. This equipment solves the problem of burrs generated through this gap. In the invention, support plates are respectively fixedly installed at both ends of the top surface of the base, and a lower mold and an upper mold are respectively installed between the support plates. A control console is fixedly installed on the upper outer wall at one end of one side of the base. A first hydraulic telescopic column is fixedly installed in the inner cavity of the middle part at the lower end of the base. A concave top frame is fixedly installed at the output end of the first hydraulic telescopic column. A second hydraulic telescopic column is fixedly installed on the outer wall of the middle part at the upper end of the outside of the support plate, and a pressing block is fixedly installed at the output end of the second hydraulic telescopic column. The invention greatly reduces the gap between the lower mold and the upper mold, reduces the burrs on the surface of the casting, improves the casting quality, and reasonably utilizes heat energy.

[0003] However, this equipment fills the liquid alloy between the upper and lower molds through several feed pipes, making it difficult to control the filling amount and injection speed of the liquid alloy, and difficult to ensure that the liquid alloy can enter the mold evenly. It is easy to occur that the filling is too fast, causing pipeline blockage and affecting the casting efficiency. And this equipment is difficult to effectively cool the upper and lower molds, easily leading to too high mold temperature and scalding workers, affecting the operation safety of workers. The forming speed of aluminum alloy is slow, and the demoulding time is long, affecting the casting efficiency of aluminum alloy. Summary of the Utility Model

[0004] The utility model provides an aluminum alloy casting equipment capable of reducing burrs on the surface of castings. Through the cooperation of a feeding assembly, an electric linear module and a blower, the filling amount and injection speed of the liquid alloy can be effectively controlled, and the upper and lower molds can be effectively cooled quickly.

[0005] In order to achieve the above object, the utility model adopts the following technical solutions:

[0016] 2. Through the structural design of the electric linear module and the fan, when the temperatures of the lower die and the upper die are too high, the fan outputs air to the square pipe, enabling the air delivery hopper to blow air into the position between a pair of support plates through the square pipe. Then, through the sliding ends of the two pairs of electric linear modules, a pair of fixed brackets move downward uniformly in the vertical direction. Through the movement of the fixed brackets, the cooling air blown out by the air delivery hopper cools the upper die and the lower die, thereby being able to quickly and effectively cool the lower die and the upper die. This can prevent workers from being scalded due to excessive die temperature, ensuring the safety of workers during operation.

A lower die 3 and an upper die 4 are respectively arranged between the pair of support plates 2.

[0025] The feeding assembly 5 is installed on the upper die 4. The feeding assembly 5 includes a feeding bin 501 and a top cover 502. The top cover 502 is arranged on the feeding bin 501. A feeding hopper 503 is arranged on one side of the top cover 502. A movable clamping plate 504 is fitted on the feeding hopper 503. A pair of sliding grooves are formed on the feeding hopper 503. Sliders are arranged on both sides of the movable clamping plate 504. The pair of sliders are matched with the pair of sliding grooves. A pneumatic push rod 505 is installed in the placement frame. The placement frame is connected to the feeding hopper 503. The placement frame is a heat-insulating frame body. Pneumatic push rods 505 are installed on both sides of the feeding hopper 503. The output end of the pneumatic push rod 505 is provided with a fixing plate 506. One end of the fixing plate 506 is connected to the movable clamping plate 504. A number of feeding pipes 401 are arranged on the top of the upper die 4. An arc-shaped groove 5011 is formed in the feeding bin 501, which can ensure that the liquid aluminum alloy enters into the feeding pipes 401. A number of through holes 5013 are formed in the arc-shaped groove 5011. The number of feeding pipes 401 is in interference fit with the number of through holes 5013. The interiors of the number of feeding pipes 401 are communicated with the interior of the feeding assembly 5. A number of diversion grooves 5012 are formed in the feeding bin 501, which can ensure that most of the liquid aluminum alloy can flow into the feeding pipes 401 along the diversion grooves 5012. The number of diversion grooves 5012 corresponds to the number of through holes 5013.

[0026] When filling the liquid aluminum alloy, start the pair of pneumatic push rods 505. Push the fixing plate 506 to move in the vertical direction through the output end of the pneumatic push rod 505, so that the movable clamping plate 504 slides in the feeding hopper 503 under the pulling of the fixing plate 506, realizing the adjustment of the gap generated between the movable clamping plate 504 and the feeding hopper 503. The alloy liquid flows into a number of diversion grooves 5012 on the feeding bin 501 through the feeding hopper 503, and then flows into the corresponding feeding pipes 401 through the diversion grooves 5012, so that the liquid aluminum alloy can enter the upper die 4 and the lower die 3 evenly, and can quickly fill the gap between the lower die 3 and the upper die 4, realizing the casting of the aluminum alloy product. Thus, the filling amount and injection speed of the liquid aluminum alloy can be effectively controlled, ensuring that the liquid aluminum alloy can enter the mold evenly, avoiding pipeline blockage caused by too fast filling, improving the casting efficiency, reducing the generation of burrs, and improving the casting quality.

[0028] When the temperatures of the lower die 3 and the upper die 4 are too high, a pair of blowers 8 are started synchronously. The wind is conveyed to the square pipe 801 through the output ends of the blowers 8, so that the air delivery hopper 9 blows the wind into the position between the pair of support plates 2 through the square pipe 801. Then, through the sliding ends of the two pairs of electric linear modules 6, a pair of fixed brackets 7 move downward uniformly in the vertical direction. Through the movement of the fixed brackets 7, the cooling wind blown out by the air delivery hopper 9 cools the whole upper die 4 and the lower die 3 evenly and quickly, so that the lower die 3 and the upper die 4 can be effectively cooled quickly, which can avoid scalding workers due to too high die temperature, ensure the safety of workers' operation, can also accelerate the forming speed of the aluminum alloy, reduce the demoulding time of the aluminum alloy, and effectively improve the casting efficiency of the aluminum alloy.
