Description

Technical Field

[0001] This invention relates to the field of tricycle manufacturing technology, specifically to an integrated die-cast aluminum alloy multi-purpose floor for tricycles and its die-casting process. Background Technology

[0002] A three-wheeled motorcycle consists of five major systems: body, interior and exterior trim, chassis, power, and electrical system. The body is composed of the front end, front floor, rear floor, left and right side panels, rear panel, and roof. The interior is composed of the dashboard, seats, carpets, decorative panels, and ceiling.

[0003] Currently, three-wheeled motorcycles are widely used for passenger transport in rural areas, suburban areas, tourist attractions, airports, train stations, bus stations, docks, and other locations. Existing three-wheeled motorcycles have a monocoque chassis, traditionally constructed from welded steel curved pipe beams or welded steel plate stampings. Some improved designs use aluminum alloys instead of steel, but the chassis structure is still made of multiple aluminum alloy plate stampings welded together using aluminum welding technology. The drawback of the existing technology is that the existing chassis floor structure is welded from more than ten independent parts, such as the front and rear floors. From processing each individual part to welding them into a whole, more than 50 steps are required, resulting in low production efficiency and high overall production costs.

[0004] Therefore, there is an urgent need for a three-wheeled vehicle integrated die-cast aluminum alloy multi-purpose floor and its die-casting process. Summary of the Invention

[0005] The purpose of this invention is to provide a three-wheeled vehicle integrated die-cast aluminum alloy multi-purpose floor and its die-casting process, so as to solve the problems mentioned in the background art.

A fan is provided on the outside of the support plate, and an air spray plate is provided on the outside of the fan. The outside of the air spray plate is fixedly connected to the outside of the support plate.

[0007] Preferably, a pressure casting machine spraying unit is fixedly connected to the top of the pressure casting machine tool, a feeding pipe is fixedly connected to the outside of the pressure casting machine spraying unit, and the top of the feeding pipe is fixedly connected to the bottom of the integral die casting mold.

[0008] Preferably, a feeding port is fixedly connected to the top of the injection unit of the pressure casting machine, and an injection pressure unit of the pressure casting machine is fixedly connected to the top of the injection unit of the pressure casting machine.

[0009] Preferably, a robotic arm is fixedly installed on the outside of the pressure casting machine tool, and the bottom of the robotic arm is adapted to the top of the fixed mold of the integrated die casting mold.

[0010] Preferably, a fixing ring is fixedly connected to the outer side of the fan, the outer side of the fixing ring is fixedly connected to the outer side of the support plate, a collecting hopper is fixedly connected to the inside of the fixing ring, the outer side of the collecting hopper is fixedly installed to the outer side of the fan, and the outer side of the collecting hopper is fixedly connected to the outer side of the spray plate.

[0011] Preferably, the collecting mechanism includes a first screen, the outer surface of which is fixedly connected to the interior of the pressure casting machine tool, a collecting hopper fixedly connected to the bottom of the first screen, a screen plate fixedly connected to the bottom of the collecting hopper, and a collecting box fixedly connected to the bottom of the screen plate.

[0012] Preferably, the bottom of the pressure casting machine tool is provided with a discharge pipe, and the outer side of the discharge pipe is fixedly connected to the outer side of the collection box.

[0013] Preferably, the top of the first screen is attached to the second screen, the bottom of the second screen is inserted into the interior of the pressure casting machine, the top of the second screen is fixedly connected to a baffle plate, the outer side of the baffle plate is fixedly connected to a handle, and the outer side of the baffle plate is adapted to the outer side of the air spray plate.

[0014] Preferably, the bottom of the pressure casting machine tool is fixedly connected to a support column, and multiple support columns are provided, which are arranged in a rectangular array.

[0015] On the other hand, a die-casting process for an integrated die-cast aluminum alloy multi-purpose floor for tricycles is also provided, with the following steps: S1 Mold Closure: The moving mold of the integrated die-casting mold is moved along the guide mechanism to fit tightly with the fixed mold of the integrated die-casting mold, completing the mold closing action and forming a closed cavity inside the mold; S2 feeding: Molten aluminum alloy is fed into the injection unit of the pressure casting machine through the feeding port; S3 Spray Filling: Start the spray pressure unit of the pressure casting machine to provide high pressure power and spray the aluminum alloy molten metal in the spray unit of the pressure casting machine into the mold cavity at high speed to complete the filling; S4 Cooling and Solidification: Keep the mold closed, allowing the liquid aluminum alloy inside the mold to cool and solidify naturally under pressure to obtain the desired workpiece shape; S5 Mold Opening and Part Removal: After the workpiece has completely solidified, the moving mold of the integrated die-casting mold moves away from the fixed mold of the integrated die-casting mold again to complete the mold opening action and expose the workpiece; then the workpiece is picked up by the robotic arm, moved out of the mold area, and sent to the next process.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention utilizes a die-casting mechanism to integrate more than ten independent parts, such as the front and rear floor of a vehicle body, into a single integral part through a single die-casting process. This reduces the more than 50 steps required for traditional steel vehicle body floor construction to just four steps, increasing production efficiency by approximately 30%. The integrated die-casting eliminates the need for separate stamping and welding of individual parts, completing the entire structure in a single forming process. The front and rear load-bearing beams are connected as a single unit, avoiding abrupt changes in cross-section and welding defects caused by welding more than ten individual parts. Welded joints often contain defects such as heat-affected zones, porosity, and incomplete fusion, making them weak points in terms of strength and rigidity. Integrated die-casting eliminates these weaknesses, improving the overall rigidity and strength of the floor by approximately 10%. The number of processes is reduced from more than 50 to 4, significantly reducing equipment usage. The reduction in manual operation, energy consumption, and inter-process logistics costs results in an overall production cost reduction of approximately 10%. Aluminum alloy material has a density of approximately 2.7 kg / dm³, only about 35% of that of steel. Compared to steel chassis floors, the aluminum alloy multi-functional floor effectively reduces weight by about 40%, improving the tricycle's range and handling performance. During the die-casting process, a dense alumina protective layer naturally forms on the finished product surface, making it resistant to rust and corrosion. In contrast, steel chassis are prone to rust and corrosion, requiring regular rust prevention treatment. Therefore, the multi-functional floor of this technology has a much longer service life than traditional steel chassis. The integrated design also incorporates the function of interior carpets, eliminating the need for separate carpet installation and reducing the risk of harmful gas emissions and flammability associated with plastic or fabric interiors. Secondly, in this invention, forced air cooling significantly shortens the cooling time of the workpiece compared to natural cooling, allowing the workpiece to proceed to subsequent processes more quickly and improving the overall production cycle. The airflow is gathered by the air hopper and then evenly sprayed through the air spray plate, ensuring that the cooling speed of all parts of the workpiece surface is consistent. This avoids thermal stress concentration and warping deformation caused by uneven cooling, and ensures the dimensional accuracy of the all-in-one floor. While cooling the workpiece, the high-speed airflow can also blow away some of the material residue and dust attached to the workpiece surface, playing a preliminary cleaning role and providing convenience for subsequent processes.

[0017] Third, in this invention, the first screen, the second screen, and the screen plate constitute a three-stage screening system, which can classify and separate aluminum alloy slag of different particle sizes, facilitating subsequent classified smelting and recycling, improving the recycling rate of aluminum alloy materials, reducing raw material waste, and the baffle plate effectively blocks and guides dust-laden airflow to prevent slag and dust from spreading and polluting the workshop air, thus protecting the occupational health of operators. The collection box centrally stores waste and discharges it regularly through the discharge pipe, avoiding the accumulation of waste in the workshop and reducing the frequency and labor intensity of manual cleaning.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention provides the following technical solutions: Example 1

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A three-wheeled vehicle integrated die-cast aluminum alloy multi-purpose floor includes a front floor 1, a rear floor 2 fixedly installed on the outside of the front floor 1, a die-casting mechanism 3 adapted to the outside of the front floor 1, a cooling mechanism 4 installed on the outside of the die-casting mechanism 3, and a collection mechanism 5 installed at the bottom of the die-casting mechanism 3. The die-casting mechanism 3 includes a pressure casting machine tool 301. A pressure casting moving mold frame 305 is mounted on the top of the pressure casting machine tool 301. An integrated die-casting moving mold 306 is fixedly connected to the outside of the pressure casting moving mold frame 305. An integrated die-casting fixed mold 308 is provided on the outside of the integrated die-casting moving mold 306. A pressure casting machine fixed mold frame 307 is fixedly connected to the outside of the integrated die-casting fixed mold 308. The outside of the pressure casting machine fixed mold frame 307 is installed with the outside of the pressure casting machine tool 301. The integrated die-casting fixed mold 308 is adapted to the front floor 1 of the vehicle body and the rear floor 2 of the vehicle body.

[0023] The top of the pressure casting machine tool 301 is fixedly connected to the pressure casting machine spraying unit 302, and the outside of the pressure casting machine spraying unit 302 is fixedly connected to the feed pipe 310. The top of the feed pipe 310 is fixedly connected to the bottom of the integrated die casting mold fixed mold 308.

[0024] A feeding port 304 is fixedly connected to the top of the injection unit 302 of the pressure casting machine, and a injection pressure unit 303 of the pressure casting machine is fixedly connected to the top of the injection unit 302 of the pressure casting machine.

[0025] A robotic arm 309 is fixedly installed on the outside of the pressure casting machine tool 301. The bottom of the robotic arm 309 is adapted to the top of the integrated die casting mold fixed mold 308.

[0026] Through the above technical solution, by cooperating the moving mold 306 and the fixed mold 308 of the integrated die-casting mold, a cavity is formed inside the mold that is consistent with the overall structure of the front floor 1 and the rear floor 2 of the vehicle body. This allows more than a dozen independent parts that originally needed to be processed separately to be combined into a single part in one die-casting process. The front and rear load-bearing beams are connected as one, avoiding abrupt changes in cross-section. The jet pressure unit 303 of the pressure casting machine provides high-pressure power to inject molten aluminum alloy into the mold cavity at high speed through the feed pipe 310, ensuring that the molten metal fills every tiny corner of the mold in a very short time, thus guaranteeing the dimensional accuracy and surface quality of the workpiece. After the mold is opened, the robotic arm 309 automatically grabs the workpiece and moves it to the next process, realizing the automated connection between the die-casting process and subsequent processes such as slag removal, flash removal, and machining, reducing manual intervention. Example 2

[0027] Please see Figure 3 , Figure 6 A three-wheeled vehicle integrated die-cast aluminum alloy multi-purpose floor, the cooling mechanism 4 includes a support plate 401, the bottom of the support plate 401 is fixedly connected to the top of the pressure casting machine tool 301, a fan 402 is provided on the outside of the support plate 401, and an air spray plate 405 is provided on the outside of the fan 402, the outside of the air spray plate 405 is fixedly connected to the outside of the support plate 401.

[0028] A fixing ring 403 is fixedly connected to the outside of the fan 402. The outside of the fixing ring 403 is fixedly connected to the outside of the support plate 401. An air collecting hopper 404 is fixedly connected inside the fixing ring 403. The outside of the air collecting hopper 404 is fixedly installed to the outside of the fan 402. The outside of the air collecting hopper 404 is fixedly connected to the outside of the air spray plate 405.

[0029] With the above technical solution, the temperature of the aluminum alloy die casting is still high when it is taken out of the mold. If natural cooling takes a long time and the cooling is uneven, the high-speed airflow generated by the fan 402 is accelerated by the air collecting hopper 404 and then evenly sprayed onto the surface of the workpiece by the air spray plate 405, which carries away a large amount of heat and makes the workpiece cool down to a suitable temperature quickly. This accelerates the stabilization process of the internal structure of the aluminum alloy. The combined design of the air collecting hopper 404 and the air spray plate 405 enables the airflow to evenly cover the surface of the workpiece, avoiding thermal stress concentration and workpiece deformation caused by inconsistent local cooling rates, and ensuring the dimensional accuracy and flatness of the multi-in-one floor. Example 3

[0030] Please see Figure 3 , Figure 7 A three-wheeled vehicle integrated die-cast aluminum alloy multi-purpose floor, the collection mechanism 5 includes a first screen 501, the outer surface of the first screen 501 is fixedly connected to the inside of the pressure casting machine tool 301, the bottom of the first screen 501 is fixedly connected to a collection hopper 505, the bottom of the collection hopper 505 is fixedly connected to a screen plate 506, and the bottom of the screen plate 506 is fixedly connected to a collection box 507.

[0031] The bottom of the pressure casting machine tool 301 is provided with a discharge pipe 508, and the outer side of the discharge pipe 508 is fixedly connected to the outer side of the collection box 507.

[0032] The top of the first screen 501 is attached to the second screen 502, the bottom of the second screen 502 is inserted into the interior of the pressure casting machine tool 301, the top of the second screen 502 is fixedly connected to the wind baffle 503, the outside of the wind baffle 503 is fixedly connected to the handle 504, and the outside of the wind baffle 503 is adapted to the outside of the air spray plate 405.

[0033] The bottom of the pressure casting machine tool 301 is fixedly connected with a support column 509. Multiple support columns 509 are arranged in a rectangular array.

[0034] Through the above technical solution, the first screen 501, the second screen 502, and the screen plate 506 constitute a three-stage screening system, which avoids the presence of impurity particles in the waste liquid, facilitates subsequent classification and recycling, and improves the resource utilization rate of waste. The baffle plate 503 effectively guides and blocks the airflow blown out by the air spray plate 405, preventing the airflow carrying material residue and dust from spreading and polluting the workshop environment, ensuring the occupational health of operators and the cleanliness of the workplace. The collection box 507 centrally stores the screened waste, and the discharge pipe 508 can periodically discharge the waste in the collection box, avoiding the waste from scattering and accumulating in the workshop, reducing the labor intensity of manual cleaning, and improving the cleanliness of the workshop and production safety. At the same time, the second screen 502 is easy to lift and replace. Example 4

[0035] Please see Figure 1 A die-casting process for an integrated aluminum alloy multi-purpose floor for tricycles, including a die-casting step, is as follows: S1 Mold Closure: The moving mold 306 of the integrated die-casting mold is moved along the guide mechanism to fit tightly with the fixed mold 308 of the integrated die-casting mold, completing the mold closure action and forming a closed cavity inside the mold. S2 feeding: Molten aluminum alloy molten metal is fed into the injection unit 302 of the pressure casting machine through the feeding port 304; S3 Spray Filling: Start the spray pressure unit 303 of the pressure casting machine to provide high pressure power and spray the aluminum alloy molten metal in the spray unit 302 of the pressure casting machine into the mold cavity at high speed to complete the filling; S4 Cooling and Solidification: Keep the mold closed, allowing the liquid aluminum alloy inside the mold to cool and solidify naturally under pressure to obtain the desired workpiece shape; S5 Mold Opening and Part Removal: After the workpiece has completely solidified, the moving mold 306 of the integrated die-casting mold moves away from the fixed mold 308 of the integrated die-casting mold again to complete the mold opening action and expose the workpiece; then the robotic arm 309 grabs the workpiece, moves it out of the mold area, and sends it to the next process.

[0036] During operation, the operator adds molten aluminum alloy metal to the injection unit 302 of the pressure casting machine through the feeding port 304. The moving mold frame 305 of the pressure casting machine moves the moving mold 306 of the integrated die casting mold until it is in contact with the fixed mold 308 of the integrated die casting mold, completing the mold closing. A closed cavity is formed inside the mold. The injection pressure unit 303 of the pressure casting machine provides high pressure, which sprays the molten aluminum alloy metal into the mold cavity at high speed through the feeding pipe 310. The high-temperature and high-pressure aluminum alloy liquid fills, cools, and solidifies in the mold. After the forming is completed, the moving mold frame 305 of the pressure casting machine moves the moving mold 306 of the integrated die casting mold away from the fixed mold 308 of the integrated die casting mold. 08. After mold opening is completed, the formed multi-functional floor workpiece is exposed. The robotic arm 309 grabs the workpiece and moves it to the next process. After the workpiece is removed from the mold, the fan 402 of the cooling mechanism 4 is started. The airflow is gathered and accelerated by the air collecting hopper 404 and then evenly sprayed onto the surface of the workpiece through the air spray plate 405 to quickly and forcibly cool the workpiece. During this process, the material residue attached to the surface of the workpiece falls off under the blowing of the airflow. At the same time, the first screen 501, the second screen 502 and the screen plate 506 of the collection mechanism 5 perform multi-stage screening of the fallen material residue. The baffle plate 503 prevents the spread of dust-laden airflow. The screened waste enters the collection box 507 for temporary storage and is discharged periodically through the discharge pipe 508.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
