[0018] A metal die-casting molding process, applied to the metal die-casting integrated molding equipment as described above, comprising:

[0019] The hydraulic device drives the movable mold base to move downward, so that the movable mold base moves toward the mold cavity, and the receiving device drives the cone to move downward, so that the cone slides in the receiving cone hole.

[0022] Technical effects and advantages of the present invention:

[0023] 1. By setting the cone and the sliding column, the storage device drives the cone to move upward, so that the cone expands elastically and is inserted into the through hole of the metal die-casting. As the cone moves upward, the edge of the largest end of the cone's outer diameter can remove the burrs on the hole wall of the through hole. There is no need to add additional steps to remove the burrs, which increases the production cycle and improves the efficiency of die-casting.

[0024] 2. By setting a pressure spring to generate elastic resistance force on the piston plate, the piston plate generates pressure on the demoulding oil in the storage space, and then the demoulding oil enters the fine gap from the connecting hole, the first connecting hole, and the second connecting hole in sequence under the action of pressure, and when the movable die seat is away from the metal die-casting, the fine gap is sprayed to the surface of the metal die-casting and the gap between the movable die, the surface of the metal die-casting and the inner wall of the mold cavity, so that the surface of the metal die-casting is not easily damaged during demoulding;

[0025] 3. When the connecting column moves upward, the shift block will be pushed against the inner wall of the notch groove, so that the shift block drives the swing arm to swing and the scroll spring accumulates elastic potential energy. After the shift block is out of contact with the inner wall of the notch groove, the elastic potential energy accumulated in the scroll spring is released, thereby driving the swing arm to swing downward quickly and causing the knocking block to knock the movable die seat quickly, so that the movable die is subjected to knocking vibration force during demolding, thereby preventing the hardware die-casting from getting stuck on the movable die during demolding and being unable to fall quickly.

A cylinder bracket 8 is fixedly connected to the top of the die base 10, and a cylinder 7 is vertically installed on the top of the cylinder bracket 8. A connecting column 22 is fixedly connected to the end of the cylinder rod of the cylinder 7. The lower end of the connecting column 22 penetrates into the movable die base 10 and is coaxially fixed with the forming column 21. The hydraulic cylinder 6 is started, and its piston rod is extended and drives the movable die base 10 to move downward, so that the movable die base 10 and the movable mold 11 move toward the mold cavity until the lower surface of the movable die base 10 is tightly pressed against the top surface of the die-casting base 1. The cylinder rod of the cylinder 7 is extended, thereby driving the connecting column 22 and the forming column 21 to slide in the movable die base 10, and the lower end of the forming column 21 penetrates out of the movable mold 11 until the lower end surface of the forming column 21 is flush with the inner bottom wall of the mold cavity;

[0039] A sliding column 20 is vertically penetrated in the die-casting base 1, and a sliding hole for the sliding column 20 to slide freely is provided in the die-casting base 1. A cone 14 is coaxially fixed to the upper end of the sliding column 20. The outer diameter of the cone 14 decreases from top to bottom. The maximum outer diameter of the cone 14 is larger than the outer diameter of the forming column 21. A plurality of fine slits 30 are provided along the axial array of the cone 14. A storage cone hole for the cone 14 to engage is provided in the die-casting base 1. A lifting cylinder 12 is vertically installed at the bottom of the die-casting base 1. The piston rod of the lifting cylinder 12 penetrates the die-casting base 1 and is rotatably connected to the connecting rod 12. The upper end face of the connecting head 16 is coaxially fixed with a tie rod 15, and the upper end of the tie rod 15 is coaxially fixed to the lower end of the sliding column 20. When the piston rod of the lifting cylinder 12 is shortened, the tie rod 15 drives the sliding column 20 to slide downward, and the cone 14 slides downward in the receiving cone hole. During the downward sliding process, the periphery of the cone 14 is squeezed by the wall of the receiving cone hole, so that the periphery of the cone 14 is squeezed along the radial inner side, and then the cone 14 is transformed from the elastic expansion deformation state to the elastic contraction deformation. At this time, the upper end face of the cone 14 is in contact with the mold cavity. The inner bottom wall of the mold is flush, and after the molding column 21 moves downward, its lower end face is against the upper end face of the cone 14. In addition, the slit 30 will be in a closed state at this time. After the cone 14 is completely engaged in the receiving cone hole, the upper side opening of the receiving cone hole is sealed by the cone 14. At this time, the external injection equipment injects molten metal into the mold cavity through the injection port 2 set on the top surface of the movable mold base 10, so that the molten metal fills the entire mold cavity. After die casting and cooling, a hardware die-casting 13 is formed in the mold cavity. First, the cylinder rod of the cylinder 7 is shortened, and drives the connecting column 22 and the molding column 21 moves upward, so that the forming column 21 is retracted into the movable mold 11. At this time, a through hole is formed on the surface of the metal die-casting 13 at the position corresponding to the forming column 21. Then the lifting cylinder 12 is started, and the piston rod of the lifting cylinder 12 is extended, thereby driving the pull rod 15, the sliding column 20 and the cone 14 to move upward. The cone 14 will gradually break away from the extrusion state with the inner wall of the receiving cone hole, so that the cone 14 will change from the elastic contraction deformation state to the elastic expansion deformation state, thereby causing the outer diameter maximum end of the cone 14 to elastically expand and be stuck in the through hole of the metal die-casting 13;

[0040] A first connecting hole 31 is provided inside the pull rod 15, and a second connecting hole 32 extending to the tapered portion 14 is provided inside the sliding column 20. The first connecting hole 31 and the second connecting hole 32 are in a through-state, and the second connecting hole 32 is connected to the slit 30. A connecting port 26 connected to the first connecting hole 31 is provided on the periphery of the pull rod 15. A storage cavity 17 is provided in the die-cast base 1, and the connecting port 26 is connected to the storage cavity 17. A piston plate 18 is mounted on the periphery of the pull rod 15. The piston plate 18 is engaged with the storage cavity 17 and can slide vertically and freely in the storage cavity 17. The lower end surface of the piston plate 18 and the bottom wall of the storage cavity 17 form a storage space, and the storage space is filled with demoulding oil. The connecting port 26 is connected to the inside of the storage space. A pressure spring 24 is vertically installed in the storage cavity 17, and the two ends of the pressure spring 24 in the elastic force direction elastically press against the storage cavity 17 one by one. The top wall and the upper end surface of the piston plate 18, when the cone 14 expands elastically, the slit 30 changes from a closed state to an open state. Since the pressure spring 24 has a downward elastic resisting force on the piston plate 18, the piston plate 18 moves downward and generates pressure on the demoulding oil in the storage space, so that the demoulding oil enters the first communicating hole 31 from the connecting port 26, and then enters the second communicating hole 32 from the first communicating hole 31 in turn, and is sprayed out from a plurality of slits 30. The outer wall of the die-casting base 1 is provided with a replenishing port that is connected to the storage space, and a manual valve (not shown in the figure) is installed on the replenishing port. By opening the manual valve, the demoulding oil can be replenished to the inside of the storage space through the replenishing port. In addition, in this embodiment, the connector 16 has a limit on the downward movement of the piston plate 18, so that after the piston plate 18 moves downward into place, the inside of the storage space can still be connected to the replenishing port;

[0041] A fixing sleeve 19 is fixedly connected to the inner top wall of the storage chamber 17, and a sliding column 20 is coaxially inserted into the middle hole of the fixing sleeve 19 and slides freely. A ball 29 is rotatably embedded in the periphery of the sliding column 20. A spiral groove 33 for the ball 29 to engage is provided on the wall of the middle hole of the fixing sleeve 19. The ball 29 rolls freely in the spiral groove 33. When the cone 14 moves upward, the ball 29 will roll in the spiral groove 33. Since the connector 16 and the piston rod end of the lifting cylinder 12 are rotatably connected, the sliding column 20 and the cone 14 are rotated. In this way, the cone 14 can more fully scrape off the burrs on the inner wall of the through hole of the metal die-casting 13 by rotating.

[0042] A hinge seat 9 is fixedly connected to the top of the movable mold seat 10, and a swing arm 3 is rotatably connected to the hinge seat 9 through an installation pivot. A knock block is fixedly connected to one end of the swing arm 3 facing the connecting column 22. A mounting sleeve 27 is fixedly connected to the side wall of the hinge seat 9. A volute spring 28 is installed in the mounting sleeve 27. Both ends of the volute spring 28 are respectively fixed to the inner wall of the mounting sleeve 27 and the periphery of the pivot. In the initial state, the volute spring 28 drives the pivot to rotate, so that the pivot drives the swing arm 3 to swing downward. A shift block 25 is fixedly connected to one end of the swing arm 3 away from the hinge seat 9. A plurality of notch grooves 23 are provided on the periphery of the connecting column 22. The shift block 25 cooperates with the notch groove 23. As the connecting column 22 moves upward, the shift block 25 moves downward. Movement, the end of the shift block 25 away from the hinge seat 9 will slide on the inner wall of the notch groove 23, that is, when the connecting column 22 moves upward, the end of the shift block 25 will alternately contact the inner wall of the notch groove 23, thereby driving the shift block 25 to move upward, and driving the swing arm 3 to swing upward along the hinge with the hinge seat 9, and at this time the pivot will begin to contract the spiral spring 28, and the spiral spring 28 accumulates elastic potential energy. When the shift block 25 is out of contact with the inner wall of the notch groove 23, the elastic potential energy accumulated in the spiral spring 28 is released, thereby driving the swing arm 3 to swing downward quickly, so that the knocking block knocks the top surface of the movable mold seat 10, thereby generating a knocking vibration force on the movable mold seat 10.

[0043] Working principle of the present invention:

[0044] Injection molding: The hydraulic cylinder 6 is started, and its piston rod is extended and drives the movable mold base 10 to move downward, so that the movable mold base 10 and the movable mold 11 move toward the mold cavity until the lower surface of the movable mold base 10 is tightly against the top surface of the die-casting base 1, and the cylinder rod of the cylinder 7 is extended, thereby driving the connecting column 22 and the molding column 21 to slide in the movable mold base 10, and the lower end of the molding column 21 passes through the movable mold 11. After the molding column 21 moves downward, its lower end surface is against the upper end surface of the cone 14. In addition, the slit 30 will be in a closed state at this time. After the cone 14 is completely engaged in the receiving cone hole, the upper side opening of the receiving cone hole is sealed by the cone 14. At this time, the external injection equipment injects molten metal into the mold cavity through the injection port 2 set on the top surface of the movable mold base 10, so that the molten metal fills the entire mold cavity. After die-casting and cooling, a hardware die-casting 13 is formed in the mold cavity;

[0045] Burr removal: Start the cylinder 7, the cylinder rod of the cylinder 7 shortens, and drives the connecting column 22 and the forming column 21 to move upward, so that the forming column 21 is retracted into the movable mold 11. At this stage, the lower end surface of the forming column 21 is flush with the lower surface of the movable mold 11. At this time, a through hole is formed on the surface of the metal die-casting 13 corresponding to the position of the forming column 21. Then the lifting cylinder 12 is started, and the piston rod of the lifting cylinder 12 is extended, thereby driving the pull rod 15, the sliding column 20 and the cone 14 to move upward, and the cone 14 will gradually The cone 14 is separated from the squeezed state of the inner wall of the receiving cone hole, so that the cone 14 is transformed from the elastic contraction deformation state to the elastic expansion deformation state, and then the end with the largest outer diameter of the cone 14 is elastically expanded and stuck in the through hole of the metal die-casting 13. As the cone 14 moves upward, the ball 29 rolls in the spiral groove 33 and drives the sliding column 20 and the cone 14 to rotate, so that the outer edge of the end with the largest outer diameter of the cone 14 can fully scrape the burrs on the inner wall of the through hole of the metal die-casting 13, reducing the blind area of ​​burr scraping;

[0046] Demolding: start the hydraulic cylinder 6 and the cylinder 7 simultaneously, the cylinder rod of the cylinder 7 continues to shorten, and then drives the connecting column 22 to move upward, and the end of the shift block 25 will alternately contact the inner wall of the notch groove 23, thereby driving the shift block 25 to move upward, and drive the swing arm 3 to swing upward along the hinge with the hinge seat 9, and at this time the pivot will begin to contract the volute spring 28, and the volute spring 28 accumulates elastic potential energy. When the shift block 25 is out of contact with the inner wall of the notch groove 23, the elastic potential energy accumulated in the volute spring 28 is released, thereby driving The swing arm 3 swings downward rapidly, so that the knocking block knocks the top surface of the movable die seat 10, thereby generating a knocking vibration force on the movable die seat 10. When the hydraulic cylinder 6 drives the movable die seat 10 and the movable die 11 to move upward, the upper surface of the metal die-casting 13 will be separated from the extrusion pressure of the movable die 11. At this time, due to the knocking vibration force on the movable die seat 10, the metal die-casting 13 is subjected to the vibration force during demolding, and is not easily stuck on the movable die 11, so that the metal die-casting 13 can fall off relatively easily, which is convenient for workers to collect.
