[0001] The present invention relates to the technical field of die-casting molding, and particularly to a die-casting molding device for processing aluminum alloy fittings of an automobile hood lock. Background Art

[0002] The buckle is an important component on the automobile hood. It is usually of a U-shaped structure and has a mounting seat at its end. The buckle is usually produced by die-casting. Since its base area is large and its thickness is thin while the buckle part is generally not too thick, this results in a relatively deep and narrow cavity in the die-casting mold corresponding to the base of the die-casting, which in turn makes it inconvenient to clean the debris and apply the release agent on the inner wall of this part of the cavity. When cleaning, due to the narrow cavity, the debris is likely to scratch the cavity wall. Summary of the Invention

[0017] Please refer to Figures 1-12 , the present invention provides a technical solution: a die-casting forming device for processing aluminum alloy fittings of automobile hood locks, including a frame body 1 and two molds 2 installed on the frame body 1 and in an inverted state, a support plate 3 is provided at the bottom of the frame body 1, and frames 4 are installed at the bottom of both molds 2 on the support plate 3, and a cleaning mechanism is provided inside the frame 4; The cleaning mechanism is used to clean the debris in the deep mold cavity of the mold 2 without scratching the inner wall of the mold cavity; The cleaning mechanism includes a belt body 5 and a rotating shaft 6 disposed within the frame body 4. The rotating shaft 6 is rotatably connected to the frame body 4 and is in contact with the inner wall of the belt body 5. A first motor 7 is fixedly connected to the frame body 4, and the output shaft of the first motor 7 is fixedly connected to the rotating shaft 6. Support assemblies one are provided on both the upper and lower sides within the belt body 5, and the bottom support assembly one is mounted on the frame body 4. The support assembly one is used to laterally expand the belt body 5. A support assembly two is provided between the two support assemblies one. The support assembly two is used to support the two support assemblies one and can simultaneously adjust the support range of the two support assemblies two. A plurality of first brushes 8 are fixedly connected to the belt body 5 at equal intervals, and the first brushes 8 are inclinedly distributed. A coating mechanism is provided on the belt body 5, including a plurality of second brushes 9 fixedly arranged on the belt body 5 at equal intervals. The first brushes 8 and the second brushes 9 are respectively distributed at the front and rear positions on the belt body 5. A feeding assembly is provided on the support plate 3 near the frame body 4. The feeding mechanism is used to sequentially apply the release agent to each second brush 9. A mold closing mechanism is provided on the frame body 1. The mold closing mechanism is used to drive the two molds 2 to close for die-casting the buckle. A driving mechanism is provided on the support plate 3. The driving mechanism is used to drive the support plate 3 to move. During operation, after the die-casting of the buckle is completed, the mold closing mechanism is started to open the two molds 2 to take out the buckle. At this time, there will be debris remaining in the deep mold cavity in the mold 2. The driving mechanism is started to drive the support plate 3 to move to the bottom of the frame body 1 and make the two belt bodies 5 on the support plate 3 respectively extend into the deep mold cavity. At this time, the first brushes 8 and the second brushes 9 on the belt body 5 are both in contact with the inner wall of the mold cavity. While the driving mechanism drives the support plate 3 to move, by continuously adjusting the vertical position of the support plate 3, it can be ensured that the first brushes 8 and the second brushes 9 on the belt body 5 always maintain a state of being in contact with the mold cavity. Before the belt body 5 extends into the mold cavity, adjust the width and length of the belt body 5 according to the width and depth of the mold cavity. By starting the support assembly one and the support assembly two, the width and width of the belt body 5 can be adjusted. During the adjustment process, the wider the belt body 5, the shorter the length. After the belt body 5 extends into the mold cavity, start the motor. The motor drives the rotating shaft 6 to rotate, and the rotating shaft 6 will drive the belt body 5 to transmit. When the belt body 5 transmits, it drives the plurality of first brushes 8 and second brushes 9 connected to it to transmit. Since the first brushes 8 are located in the front position of the second brushes 9, when the support plate 3 moves forward, the first brushes 8 will first come into contact with the inner wall of the mold cavity and clean the debris on the inner wall of the mold cavity. Since the mold 2 is in an inverted state, when the first brushes 8 clean the debris on the inner wall of the mold cavity, the debris will directly fall downward, which can avoid scratching the inner wall of the mold cavity. Since the first brushes 8 are in an inclined state, when cleaning the debris, the first brushes 8 will push the debris forward, which can prevent the debris from falling into the frame body 4. After the first brush 8 cleans the inner wall of the mold cavity, the feeding assembly applies a fixed amount of release agent onto the second brush 9. After the belt body 5 drives the second brush 9 into the mold cavity, the second brush 9 will automatically brush the release agent onto the inner wall of the mold cavity. Since the mold 2 is in an inverted state, the excess release agent on the inner wall of the mold cavity will automatically flow down. At this time, a receiving tool can be installed at the rear side of the frame 4 to catch the flowing release agent. The second brush 9 can brush an excessive amount of release agent on the inner wall of the mold cavity, and the excess release agent can automatically flow out and be recycled, which can ensure that the inner wall of the mold cavity is fully coated with release agent and the release agent in the mold cavity is not excessive. While ensuring the die-casting effect of the mold 2, it can effectively improve the convenience of demolding the mold 2.

[0018] Refer to Figures 5-8 As a further solution of the present invention, the first support assembly includes a first connecting block 10 and struts 11 located on the left and right sides of the first connecting block 10. The struts 11 are in contact with the inner surface of the belt body 5. Two first connecting rods 12 are rotatably connected to the struts 11. At the other ends of the two first connecting rods 12, there is a second connecting block 13 that is rotatably connected to the four first connecting rods 12 on the left and right sides simultaneously. The first connecting rods 14 are symmetrically and rotatably connected to the left and right sides of the first connecting block 10, and the other ends of the first connecting rods 14 are rotatably connected to the two first connecting rods 12 on the same side. A self-locking first lead screw 15 is rotatably connected to the first connecting block 10. The first lead screw 15 penetrates through the second connecting block 13 and is threadedly connected to the second connecting block 13. Four sliders 16 are slidably connected to the frame 4, and the four sliders 16 are respectively rotatably connected to the front and rear ends of the lower two struts 11. During operation, by driving the rotation of the first lead screw 15, the first lead screw 15 pulls the first connecting block 10 and the second connecting block 13 closer. When the first connecting block 10 and the second connecting block 13 approach, under the action of the first connecting rod 14, the first connecting rod 14 will push the strut 11 outward. When the left and right struts 11 move outward simultaneously, the distance between the two struts 11 becomes larger at this time, and the width of the belt body 5 will become wider.

[0019] Refer to Figures 5-7 As a further solution of the present invention, the second support assembly includes a telescopic rod 17 located between the upper and lower first lead screws 15. The telescopic rod 17 has elasticity, and the upper and lower ends of the telescopic rod 17 are respectively fixedly connected to the upper and lower second connecting blocks 13. The end of the first lead screw 15 is inserted into the telescopic rod 17 and is vertically slidably connected to the telescopic rod 17. A screw 18 is threadedly connected to the lower part of the telescopic rod 17, and the screw 18 is used to lock the telescopic rod 17. An adjusting unit is provided on the telescopic rod 17, and the adjusting unit is used to adjust the distance between the two struts 11. The adjusting unit includes a first bracket 19. The first bracket 19 is fixedly connected to the frame 4, and a first bevel gear 20 and a second bevel gear 21 that mesh with each other are rotatably connected to the first bracket 19. The first bevel gear 20 is sleeved on the telescopic rod 17 and is slidably connected to the telescopic rod 17. A rotating disk 22 is fixedly connected to the front end of the second bevel gear 21. During operation, the elasticity of the telescopic rod 17 can support the upper connecting block two 13 above the belt body 5, so as to tighten the belt body 5. During operation, the telescopic rod 17 can be locked by rotating the screw 18, so as to fix the shape of the belt body 5 and prevent the belt body 5 from deforming. When it is necessary to adjust the width of the belt body 5, the turntable 22 is started to rotate at this time. The turntable 22 drives the bevel gear two 21 to rotate, the bevel gear two 21 drives the bevel gear one 20 to rotate, and the bevel gear one 20 will drive the telescopic rod 17 to rotate. The telescopic rod 17 drives the lead screws one 15 on the upper and lower sides to rotate at the same time. When the lead screws one 15 rotate, the distance between the two corresponding support rods 11 can be adjusted.

[0020] Refer to Figures 9-10 As a further solution of the present invention, the feeding assembly includes a bracket two 23 fixedly connected to the support plate 3. The bracket two 23 is adjustable in position on the support plate 3 and a fixed frame 24 is fixedly connected to the bracket two 23. A sponge 25 is installed in the fixed frame 24. A push plate 26 is arranged outside the sponge 25 in the fixed frame 24. A material box 27 containing a release agent is fixed on the bracket two 23. A material pipe one 28 is fixed to the bottom of the material box 27. A valve 29 is installed on the material pipe one 28 and the end of the material pipe one 28 is slidably connected to a material pipe two 30. The material pipe two 30 is fixedly connected to the push plate 26 and the material pipe two 30 penetrates through the push plate 26. An extrusion unit is arranged on the bracket two 23 for extruding the release agent stored in the sponge 25 by extruding the sponge 25. A feeding unit is arranged on the bracket two 23 for briefly opening the valve 29 to allow the release agent in the material box 27 to flow into the sponge 25 after the extrusion unit extrudes the release agent in the sponge 25. The extrusion unit includes a push frame 31 slidably connected to the fixed frame 24. The push frame 31 is fixedly connected to the push plate 26 and a connecting rod three 32 is rotatably connected to the bottom of the push frame 31. A turntable 33 is rotatably connected to the front side of the frame body 4. The turntable 33 is fixedly connected to the rotating shaft 6. One end of the bottom side of the connecting rod three 32 is rotatably connected to the edge part of the turntable 33. The feeding unit includes a driving block 34 fixedly connected to the valve core in the valve 29. A baffle 35 is arranged on the side of the driving block 34 away from the valve 29. The baffle 35 is fixedly connected to the bracket two 23. A spring 36 is connected between the baffle 35 and the driving block 34 and two support blocks 37 are fixedly connected to the side of the baffle 35 close to the driving block 34. The side of the support block 37 close to the driving block 34 is inclined upward. Two sliding rods one 38 are slidably connected to the driving block 34. The bottom ends of the sliding rods one 38 are in contact with the support blocks 37. A sliding rod two 39 is slidably connected to the push frame 31 at the same height position as the sliding rods one 38. The direction of the sliding rod two 39 close to the valve 29 is a slope. During operation, when the first motor 7 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the turntable 33 to rotate. The turntable 33 drives the push frame 31 to slide back and forth left and right through the third connecting rod 32. When the push frame 31 moves towards the valve 29, it drives the push plate 26 to squeeze the sponge 25. At the same time, one of the second brushes 9 just moves to a position where it fits the sponge 25. As the belt body 5 drives the second brush 9 to move upward, the push plate 26 continuously squeezes the sponge 25, and the release agent in the sponge 25 is continuously extruded onto the second brush 9; when the second brush 9 separates from the sponge 25, the push frame 31 drives the push plate 26 to reset. During the reset process of the push frame 31, the inclined surface part of the second sliding rod 39 on the push frame 31 will fit with the first sliding rod 38 and push the first sliding rod 38 to move. When the first sliding rod 38 moves, it drives the driving block 34 to move, and the driving block 34 drives the valve core to move. At this time, the valve 29 is opened, and the release agent in the material box 27 flows into the sponge 25 through the first material pipe 28 and the second material pipe 30; as the push frame 31 continues to reset, the second sliding rod 39 pushes the first sliding rod 38 to continue moving. When the first sliding rod 38 moves, it gradually moves downward along the track of the support block 37. When the first sliding rod 38 moves along the support block 37 to the bottom position of the second sliding rod 39, at this time, under the action of the spring 36, the driving block 34 automatically resets, and the valve 29 closes again; When the second sliding rod 39 moves towards the valve 29, the inclined surface part on the second sliding rod 39 will fit with the first sliding rod 38, and the first sliding rod 38 will push the second sliding rod 39 to move upward through the inclined surface of the second sliding rod 39.
