Description

Technical Field

[0001] This utility model relates to the field of die-casting mold technology, specifically to a die-casting mold for an aluminum alloy fuel tank bracket. Background Technology

[0002] Die casting molds are tools used to cast metal parts, specifically for completing the die casting process on a specialized die casting and forging machine. The basic die casting process involves molten metal being poured into the mold cavity at low or high speed. The mold has movable cavity surfaces, which are pressurized and forged as the molten metal cools, eliminating shrinkage cavities and porosity defects in the blank and achieving a forged, fragmented grain structure. This significantly improves the overall mechanical properties of the blank.

[0003] Chinese patent document CN222133409U discloses a novel die-casting mold for aluminum alloy foot pedal components. The mold includes a worktable, a first support fixedly mounted on the upper surface of the worktable, a hydraulic cylinder fixedly mounted on the left surface of the first support, and a movable die-casting mold fixedly mounted at the output end of the hydraulic cylinder. This invention, through the cooperation of the worktable, first support, hydraulic cylinder, movable die-casting mold, push rod, top plate, aluminum alloy liquid processing tank, second support, fixed die-casting mold, sealing groove, slide groove, sealing push plate, slide rod, sleeve, damping spring, and other structures, can add an automatic demolding device to the die-casting mold itself while ensuring die-casting sealing. This allows the product to be directly demolded from the mold after the two molds separate following molding, facilitating rapid entry into the next die-casting operation and improving the efficiency of die-casting aluminum alloy foot pedal components.

[0004] However, in the above-mentioned solutions and existing technologies, the moving mold moves under the drive of the hydraulic cylinder and seals with the fixed mold. Aluminum alloy liquid is injected into the cavity formed by the moving mold and the fixed mold through the injection pipe, and then the aluminum alloy fuel tank bracket is die-cast. When the aluminum alloy fuel tank bracket is demolded, some debris will remain in the mold cavity. Usually, the operator needs to use a brush to clean out the debris, which is cumbersome and inconvenient and needs to be improved and optimized.

[0005] Therefore, this utility model proposes an aluminum alloy fuel tank bracket die-casting mold to solve the above problems. Utility Model Content

[0019] The trapezoidal jet plate 8 is movably positioned between the fixed mold 1 and the moving mold 2, making it easy to adjust the position of the trapezoidal jet plate 8 to adapt to different cleaning needs.

[0020] The trapezoidal jet plate 8 has air nozzles 9 evenly spaced on both sides of its inclined surface. The air nozzles 9 are inclined downwards. An air inlet hose 10 is connected to the top of the trapezoidal jet plate 8. The air inlet hose 10 passes through the cross plate 7. The L-shaped support plate 11 is rotatably mounted on the side wall of the L-shaped frame plate 5.

[0021] The air nozzles 9 on both sides are tilted downwards and aligned with the inner cavities of the fixed mold 1 and the moving mold 2, which can thoroughly clean the debris in the mold cavity. The air inlet hose 10 is connected to the output end of the blower to provide a gas source for the trapezoidal jet plate 8.

[0022] The inner sidewall of the L-shaped support plate 11 is in close contact with the bottom wall of the cross plate 7. A positioning groove 12 is provided on the end wall of the L-shaped support plate 11. An L-shaped protrusion plate 13 is connected to the end wall of the L-shaped frame plate 5. A positioning pin 14 is movably inserted into the end wall of the L-shaped protrusion plate 13. A pull frame 15 is connected to the top of the positioning pin 14. The bottom end of the positioning pin 14 is inserted into the positioning groove 12.

[0023] The L-shaped support plate 11 is rotatably mounted on the side wall of the L-shaped frame plate 5 to support the cross plate 7. The bottom end of the positioning pin 14 is inserted into the positioning groove 12 to achieve positioning of the L-shaped support plate 11.

[0024] The positioning pin 14 is fixedly fitted with a push plate 16. A trapezoidal slider 17 is connected to the side wall of the push plate 16. A trapezoidal groove 18 is opened on the side wall of the L-shaped protrusion 13 and is movably engaged with the trapezoidal slider 17. A spring 19 is fitted on the positioning pin 14. The two ends of the spring 19 are in contact with the inner side wall of the push plate 16 and the L-shaped protrusion 13, respectively.

[0025] The trapezoidal slider 17 is movably engaged with the trapezoidal groove 18 to ensure the stability of the push plate 16 movement. The spring 19 resets and pushes the push plate 16 and the positioning pin 14 to provide power for downward movement.

[0026] A trapezoidal moving groove 20 is provided on the end wall of the L-shaped protrusion 13. A fixed magnetic block 21 is fixedly embedded on the side wall of the trapezoidal moving groove 20. A trapezoidal magnetic block 22 is movably engaged in the trapezoidal moving groove 20. The trapezoidal magnetic block 22 and the fixed magnetic block 21 attract each other. An L-shaped pad 23 is connected to the end wall of the trapezoidal magnetic block 22. The end of the L-shaped pad 23 contacts the top of the pull frame 15.

[0027] The end of the L-shaped pad 23 contacts the top of the pull frame 15 to keep the positioning pin 14 unlocked, and the end of the L-shaped pad 23 contacts the bottom of the pull frame 15 to facilitate support for the pull frame 15.

[0028] Start hydraulic cylinder 3. The output end of hydraulic cylinder 3 pushes the moving mold 2 towards the fixed mold 1 until the moving mold 2 and the fixed mold 1 are sealed and fitted together, forming a cavity for die-casting aluminum alloy oil tank bracket. Subsequently, molten aluminum alloy is injected into the cavity through the injection pipe 4 on the fixed mold 1. After the molten aluminum alloy cools and solidifies, the hydraulic cylinder 3 drives the moving mold 2 to reset, completing the die casting of the aluminum alloy fuel tank bracket. After the aluminum alloy fuel tank bracket is demolded, if there are residual debris in the mold cavity, the operator first moves the end of the L-shaped pad 23 to separate it from the top of the pull frame 15, and then pulls the pull frame 15. The pull frame 15 drives the positioning pin 14 to move upward, and the positioning pin 14 drives the push plate 16 to compress the spring 19. At the same time, the trapezoidal slider 17 slides upward in the trapezoidal slide groove 18 until the bottom end of the positioning pin 14 disengages from the positioning groove 12 on the L-shaped support plate 11, completing the unlocking of the L-shaped support plate 11. Then, the L-shaped pad 23 is moved in the trapezoidal moving groove 18. Since the trapezoidal magnetic block 22 and the fixed magnetic block 21 attract each other, the L-shaped pad 23 can be fixed at the bottom of the pull frame 15 to support the pull frame 15 and keep the L-shaped support plate 11 in the unlocked state. Then, rotate the L-shaped support plate 11 so that it no longer supports the cross plate 7. At this time, the cross plate 7 can be moved within the cross groove 6 with the help of the handle according to the position of the mold cavity. The cross plate 7 drives the trapezoidal air jet plate 8 to move up and down between the fixed mold 1 and the moving mold 2, and adjust it to a suitable cleaning position. Gas is introduced into the trapezoidal air jet plate 8 through the air inlet hose 10. The gas is sprayed out at an angle downward through the air nozzles 9 on both sides of the trapezoidal air jet plate 8, blowing away the debris in the mold cavity. The operation is simple. The air jets are sprayed out at an angle downward through the air nozzles 9, which quickly blow away the debris remaining in the mold cavity. There is no need for the operator to manually clean the debris with a brush, which greatly simplifies the cleaning operation process.
