Description

Technical Field

[0001] The present invention relates to the technical field of die-casting machines, and more particularly to a demoulding device for a die-casting machine. Background Art

[0002] A die casting machine is a device used to make metal castings by injecting molten metal into a mold under high pressure. The die casting process is widely used in industries such as automobiles, aerospace, electronics and home appliances because it can efficiently produce metal parts with complex shapes, high precision and high quality.

[0003] After die-casting of a circular workpiece processed by a horizontal die-casting machine is completed, the demoulding device directly pushes out the workpiece, and then the workpiece directly falls into the storage box. The existing demoulding device cannot protect the workpiece well. Directly pushing it down will not only cause the workpiece to fall and be damaged, but also the workpieces will collide with each other and make a collision sound, resulting in a noisy production environment and unnecessary noise pollution. Before each die-casting of the workpiece, the worker needs to manually spray the demoulding agent to facilitate the smooth demoulding of the workpiece. Manual spraying not only requires repeated operations, but also makes it difficult to ensure the uniformity of spraying, reducing the demoulding effect. Therefore, it is necessary to propose a demoulding device for a die-casting machine to solve the above problems. Summary of the invention

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. During the die-casting operation, the lifting block drives the die-casting mechanism to slide downward. First, the pressure plate pushes the pressure rod to drive the piston column in the spray ring to slide downward, and the release agent in the liquid supply cavity is evenly sprayed out from the nozzle; the sliding of the piston column in the liquid supply cavity can not only quantitatively absorb the release agent into the liquid supply cavity, but also quantitatively spray the release agent in the liquid supply cavity evenly into the die-casting tank through the nozzle, thereby achieving uniform and controlled spraying of the release agent.

When the pressure plate contacts the top surface of the material transfer ring, the first rack on the pressure plate meshes with the rotating gear, and the spray ring is driven to rotate through the cooperation of the rotating gear and the bevel gear ring, so that the multiple nozzles on the inner side of the spray ring swing, so that the release agent sprayed by the nozzles is evenly covered in the die-casting groove in a circumferential manner; moreover, the piston column can also drive the nozzle to swing up and down through the meshing of the second rack and the swing gear, thereby increasing the coverage range of the nozzle and further improving the effect of spraying the release agent by the nozzle.

[0024] 3. The head of the die-casting head enters the die-casting tank for die-casting operation. When the die-casting is completed, the die-casting head is taken out of the die-casting tank, and the tray can simultaneously push the die-casting upward into the through hole. Then the moving mechanism drives the transfer ring to slide horizontally, and the transfer ring pushes the die-casting through the through hole to the conveyor belt for transportation. In this way, the die-castings will not contact each other, avoiding damage to the die-castings. At the same time, the action is gentle and quiet, which greatly reduces the noise generated during the processing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1, please refer to Figure 1-9 As shown, the present invention discloses a die-casting machine demoulding device, comprising a material receiving mechanism 1, the material receiving mechanism 1 comprises a die-casting seat 11, and a guide groove 13 is provided on the top surface of the die-casting seat 11;

[0038] A lifting mechanism 2 is installed on the side of the die casting seat 11. The lifting mechanism 2 includes a column 21 installed on the side of the die casting seat 11. A lifting block 25 is slidably connected to the side of the column 21.

[0039] The bottom surface of the lifting block 25 is provided with a die-casting mechanism 3, and the die-casting mechanism 3 includes a die-casting head 31 installed on the bottom surface of the lifting block 25;

[0040] The top surface of the die-casting seat 11 is provided with an ejection mechanism 4, and the ejection mechanism 4 includes a die-casting groove 41 provided on the top surface of the die-casting seat 11, and a tray 44 is slidably connected in the die-casting groove 41;

[0041] The top surface of the die casting seat 11 is slidably provided with a material shifting mechanism 6, which includes a material shifting ring 61 slidably connected to the top surface of the die casting seat 11, and the material shifting ring 61 is slidably connected to the top surface of the die casting seat 11, and a through hole 62 is penetrated in the middle of the material shifting ring 61, and a rotating cavity 63 is provided in the material shifting ring 61, and the rotating cavity 63 is communicated with the through hole 62;

[0042] A spray mechanism 7 is installed in the rotating chamber 63, and the spray mechanism 7 includes a rotating gear 71 rotatably connected to the rotating chamber 63. A spray ring 72 is rotatably connected to the rotating chamber 63. A bevel gear ring 73 is provided on the outer side of the spray ring 72. The rotating gear 71 is meshed with the bevel gear ring 73. A plurality of spray heads 792 are installed in an array on the inner side of the spray ring 72.

[0043] Initial state, as attached Figure 1 When die-casting is performed, the lifting block 25 slides downward along the column 21, driving the die-casting mechanism 3 to descend. First, during the descent of the die-casting head 31, the pressure plate 391 first contacts the plurality of pressure rods 67 protruding from the top of the material transfer ring 61. The pressure of the pressure plate 391 causes the pressure rods 67 to slide toward the inside of the material transfer ring 61, thereby pushing the connecting ring 78 downward. The connecting ring 78 drives the piston column 77 to slide downward. The piston column 77 slides in the liquid supply cavity 74, and squeezes the release agent in the liquid supply cavity 74 into the nozzle 792 through the liquid infusion tube 793. The nozzle 792 evenly sprays the release agent in the die-casting tank 41 and on the tray 44. There is a certain distance between the pressure plate 391 and the bottom end of the die-casting head 31. The pressure plate 391 contacts the pressure rod 67 and presses the pressure rod 67 into 61 and then contacts the top surface of the transfer ring 61. The die-casting head 31 continues to descend, and the connecting column 36 slides in the slide groove 32. In the process when the bottom end of the die-casting head 31 slides down to the same level as the pressure plate 391, the piston column 77 just completely presses out the release agent in the liquid supply chamber 74, and then the die-casting head 31 continues to slide down, passes through the through hole 62 on the transfer ring 61, and enters the die-casting groove 41 until the top end of the connecting column 36 slides to the top end of the slide groove 32, and the lifting block 25 and the die-casting head 31 stop sliding down. The die-casting head 31 then injects the molten metal into the die-casting tank 41, and the molten metal quickly cools and solidifies in the space formed by the die-casting tank 41, the die-casting head 31 and the tray 44 to form a die-casting part 9 (the bottom of the base 43 contacts the bottom surface of the die-casting tank 41 to ensure that the base 43 and the tray 44 will not move due to the filling of the molten metal and the pressure).

[0044] Then the lifting block 25 drives the die casting head 31 to rise, and the die casting head 31 is separated from the die casting groove 41 and the through hole 62, and the tray 44 is released at the same time, and the tray 44 pushes the die casting part 9 upward into the through hole 62 (the top surface of the tray 44 is at the same level as the top surface of the die casting seat 11). During the rising process of the die casting head 31, the connecting column 36 slides relative to the slide groove 32 until the top end of the connecting column 36 moves to the bottom end of the slide groove 32, and then the die casting head 31 drives the pressure plate 391 to continue to rise through the connecting column 36 until it is completely reset.

[0045] After the pressure plate 391 leaves the top surface of the material transfer ring 61, the fourth spring 75 in the liquid supply chamber 74 pushes the piston column 77 upward, and the piston column 77 pushes the pressure rod 67 to reset through the connecting ring 78; suction is generated during the upward sliding of the piston column 77, and the mold release agent in the ring chamber 64 is sucked into the liquid supply chamber 74 through the connection between the liquid pipe 76 and the liquid distribution pipe 66, thereby filling the liquid supply chamber 74. The liquid storage chamber 53 in the moving block 51 is filled with mold release agent, which continuously enters the ring chamber 64 through the liquid injection pipe 65, thereby providing mold release agent for each liquid supply chamber 74; each time the piston column 77 slides down, all the mold release agent in 74 will be pressed into the nozzle 792, and each time it rises, the mold release agent in the ring chamber 64 will be sucked into the liquid supply chamber 74, thereby realizing quantitative supply, so that the volume of mold release agent sprayed by the nozzle 792 each time is the same, and then the amount of mold release agent sprayed in the die casting groove 41 each time is controlled to be the same. Moreover, both the liquid passage tube 76 and the liquid infusion tube 793 are equipped with a one-way valve 100. When the piston column 77 slides downward, the one-way valve 100 in the liquid passage tube 76 is closed, and the one-way valve 100 in the liquid infusion tube 793 is opened, so that the release agent in the liquid supply cavity 74 can enter the nozzle 792 through the liquid infusion tube 793; when the piston column 77 slides upward, the one-way valve 100 in the liquid passage tube 76 is opened, and the one-way valve 100 in the liquid infusion tube 793 is closed, so that the release agent in the annular cavity 64 enters the liquid supply cavity 74 through the liquid distribution tube 66 and the liquid passage tube 76, thereby quantitatively replenishing the release agent.

[0046] Then the moving block 51 slides in the guide groove 13, driving the material transfer ring 61 to move together, and the material transfer ring 61 drives the die casting 9 to move through the through hole 62. When the moving block 51 reaches the other end of the guide groove 13, the material transfer ring 61 just drives the die casting 9 to move to the conveyor belt 12, and the conveyor belt 12 conveys the die casting 9. Then the moving block 51 drives the material transfer ring 61 to reset.

[0047] Example 2: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 9 The material receiving mechanism 1 further includes a conveyor belt 12 installed on the side of the die casting seat 11 , and a guide rail 14 is installed in the guide groove 13 .

[0053] A reset mechanism 8 is installed inside the die-casting seat 11, and the reset mechanism 8 includes a column 81 fixed to the bottom of the lifting block 25. A socket 82 is provided on the top surface of the die-casting seat 11. A sinker 83 is slidably connected to the die-casting seat 11 near the socket 82. A fifth spring 84 is installed at the bottom end of the sinker 83, and a pressure groove 85 is provided on the side of the sinker 83. A sixth spring 86 is installed inside the die-casting seat 11. A movable plate 87 is installed on the top of the sixth spring 86, and one end of the movable plate 87 is slidably connected to the inside of the pressure groove 85. A limiting head 88 is fixed on the top surface of the movable plate 87. A limiting block 891 is slidably connected to the inside of the die-casting seat 11. The head of the limiting block 891 is slidably connected to the socket 82, and the head of the limiting block 891 contacts the top of the connecting rod 45. A seventh spring 89 is also installed inside the die-casting seat 11. One end of the seventh spring 89 is installed on the limiting block 891, and a limiting groove 892 is provided at the bottom of the limiting block 891.

[0054] A lifting groove 22 is provided on the side of the column 21 . During die casting, the motor 24 drives the stud 23 to rotate in the lifting groove 22 , and the stud 23 drives the lifting block 25 to slide downward in the lifting groove 22 .

[0055] In order to enable the die casting head 31 to continue to slide downward after the pressure plate 391 pushes the pressure rod 67 into the material transfer ring 61 and the pressure plate 391 contacts the top surface of the material transfer ring 61, a locking block 34 is provided at the bottom end of the slide groove 32. In the process of the pressure plate 391 contacting the material transfer ring 61, the locking column 37 protruding from the bottom of the pressure plate 391 will contact the top surface of the material transfer ring 61 before the pressure plate 391, and the locking column 37 is pushed into the connecting column 36 by the material transfer ring 61. The locking column 37 compresses the second spring 39 and drives the pin block 38 at the top end to slide out of the locking groove 35, releasing the locking block 34. Since the bottom surface of the locking block 34 is an inclined surface, when the die casting head 31 and the connecting column 36 slide relative to each other (according to the attached Figure 8The locking block 34 is finally disengaged from the groove on the connecting post 36 that matches the locking block 34, and the connecting post 36 slides upward in the chute 32, and the inner side wall of the connecting post 36 always presses the locking block 34 inside the die-casting head 31, thereby ensuring that when the pressure plate 391 contacts the top surface of the material transfer ring 61, the locking block 34 immediately releases the lock on the connecting post 36, allowing the connecting post 36 to slide in the chute 32, and then the die-casting head 31 can continue to slide downward; after the die-casting head 31 slides upward, the connecting post 36 slides downward along the chute 32 relative to the die-casting head 31, and the connecting post 36 is pressed downward by the first spring 33. When 36 slides to the bottom end of the slide groove 32, the groove on the connecting column 36 that is adapted to the locking block 34 is aligned with the locking block 34, and the first spring 33 pushes the locking block 34 into the groove, and then the die-casting head 31 continues to rise. Since the connecting column 36 is connected to the die-casting head 31 through the locking block 34, the die-casting head 31 drives the connecting column 36 to rise together, and the connecting column 36 drives the pressure plate 391 to rise. At this time, the pressure of the material shifting ring 61 on the bottom of the locking column 37 gradually decreases, and then the second spring 39 gradually pushes the locking column 37 to slide downward, and the bottom end of the locking column 37 protrudes from the bottom surface of the pressure plate 391 again, and the pin block 38 at the top of the locking column 37 is reinserted into the locking groove 35 on the top surface of the locking block 34, so that the locking block 34 cannot move, thereby making the die-casting head 31 and the connecting column 36 relatively fixed.

[0056] As the lifting block 25 slides downward, the plug post 81 at the bottom thereof moves downward together and is inserted into the insertion hole 82 on the die casting seat 11. When the die casting head 31 reaches the die casting groove 41 for die casting, the bottom end of the plug post 81 reaches the bottom end of the insertion hole 82, and the plug post 81 contacts and squeezes the limit block 891 at the bottom end of the insertion hole 82, and the limit block 891 slides to the right under pressure (see the attached diagram). Figure 5The limiting head 88 drives the movable plate 87 to slide downward and compresses the sixth spring 86. Then the limiting groove 892 is aligned with the limiting head 88, and the limiting head 88 loses the pressure of the limiting block 891. The sixth spring 86 pushes the movable plate 87 and the limiting head 88 to reset upward. The limiting head 88 enters the limiting groove 892 to lock the limiting block 891. After the limiting block 891 is pushed away by the plug post 81, its head no longer contacts the top of the connecting rod 45 (assuming that the connecting rod 45 of an L-shaped structure is composed of a long side and a short side, the long side is horizontally arranged, and the short side is vertically arranged. The push block 46 is fixed to the side of the short side of the connecting rod 45. Initially, the bottom surface of the head of the limiting block 891 contacts the top of the short side of the connecting rod 45). After die casting is completed, the die casting mechanism 3 moves upward, and the lifting block 25 drives the plug 81 to slide out of the plug hole 82. Under the elastic force of the third spring 42 (in the initial state, the third spring 42 is in the compressed state of the base 43), the base 43 drives the tray 44 to slide upward (according to the attached Figure 3orientation), the tray 44 inserts the die-casting 9 into the through hole 62. At the same time, the base 43 also drives the connecting rod 45 to slide upward, the short side of the connecting rod 45 enters the socket 82, and the short side drives the push block 46 to rise until it hits the bottom surface of the sinking block 83. Then the linear motor 52 at the bottom of the moving block 51 is started, driving the moving mechanism 5 and the material transfer mechanism 6 to slide along the guide groove 13, the linear motor 52 moves along the guide rail 14 in the guide groove 13, and the material transfer ring 61 drives the die-casting 9 in the through hole 62 to move, and pushes the die-casting 9 onto the conveyor belt 12 (the linear motor 52 is also called a linear motor, which directly converts electrical energy into linear motion. A permanent magnet or coil is installed on the linear motor 52, and another magnet or coil is correspondingly installed on the guide rail 14. The linear motor 52 is driven by electromagnetic force to move along the guide rail 14). During this process, the material transfer ring 61 contacts and pushes the sinking block 83, and the sinking block 83 slides downward into the die-casting seat 11. While the sinking block 83 compresses the fifth spring 84, its bottom pushes the connecting rod 45 downward through the pushing block 46, and the connecting rod 45 drives the base 43 and the tray 44 to slide downward, and the base 43 compresses the third spring 42 again. When the sinking block 83 completely enters the die-casting seat 11, the bottom surface of the base 43 just contacts the bottom surface of the die-casting groove 41. During this process, the pressing groove 85 on the side of the sinking block 83 slides relative to the movable plate 87. When the movable plate 87 contacts the top of the pressing groove 85, the sinking block 83 presses the movable plate 87 downward. The movable plate 87 compresses the sixth spring 86 and drives the limit head 88 to slide out of the limit groove 892. Then the limit block 891 is unlocked, and the seventh spring 89 pushes the limit block 891 to slide to the left, and its head contacts the top of the short side of the connecting rod 45 again, so that the entire ejection mechanism 4 will not rise. Afterwards, the material transfer ring 61 returns to the initial position and no longer conflicts with the sinking block 83. The fifth spring 84 pushes the sinking block 83 upward, and the sinking block 83 and the pressing groove 85 are reset. The pressing groove 85 no longer conflicts with the movable plate 87. The sixth spring 86 pushes the movable plate 87 and the limit head 88 to rise to the initial position.

[0057] The top of the sinking block 83 and the head and tail of the limit block 891 are all inclined surfaces. The top of the sinking block 83 is an inclined surface so that the material transfer ring 61 can be pushed into the die-casting seat 11 when it hits the sinking block 83; the inclined surface of the head of the limit block 891 is so that the plug column 81 can be pushed to the right when it hits the limit block 891; the inclined surface of the tail of the limit block 891 is so that it can slide to the right and push the limit head 88 and the movable plate 87 to slide downward when it hits the limit head 88.

[0058] Example 3: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 9The spraying mechanism 7 also includes a plurality of liquid supply chambers 74 arrayed in the spraying ring 72, each of which is equipped with a fourth spring 75, and each of which is connected to a liquid through tube 76 on the bottom end side of each liquid supply chamber 74, and the liquid through tube 76 is connected to the corresponding liquid distribution tube 66, and each of which is slidably connected to a piston column 77, and the bottom end of each piston column 77 abuts against the corresponding fourth spring 75, the top ends of the plurality of piston columns 77 are fixed to the bottom surface of the connecting ring 78, and the bottom ends of the plurality of pressure rods 67 abut against the top surface of the connecting ring 78, and a second rack 79 is fixed to the side of each piston column 77, and a swing gear 791 is installed on each nozzle 792, and each second rack 79 is meshedly connected with the corresponding swing gear 791, and each nozzle 792 is connected to a liquid infusion tube 793, and the other end of each liquid infusion tube 793 is connected to the corresponding liquid supply chamber 74.

[0059] In order to further improve the spraying uniformity and effect of the release agent, during the descending process of the pressure plate 391, the first rack 392 thereon will be inserted into the through groove 68 provided on the top of the material transfer ring 61, and the first rack 392 will be meshed and connected with the rotating gear 71, and drive the rotating gear 71 to rotate, and the rotating gear 71 drives the spray ring 72 to rotate in the rotating chamber 63 through the bevel gear ring 73 (the spray ring 72 drives the piston column 77 to rotate together during the rotation process, and the connecting ring 78 fixed on the piston column 77 can make the pressure column 67 contact the connecting ring 78, so as to ensure that the pressure column 67 can always push the piston column 77 to slide), and the spray ring 72 drives the multiple nozzles 792 installed on the inner side thereof to rotate synchronously, so that during the spraying process of the nozzle 792, the release agent can be sprayed in the die casting tank 41 in a circumferential, multi-directional and uniform manner. The liquid distribution pipe 66 and the liquid distribution pipe 76 are connected by a corrugated pipe, and the connection between the liquid distribution pipe 66 and the liquid distribution pipe 76 will not be affected during the rotation of the spray ring 72. At the same time, as the piston column 77 slides downward, the second rack 79 is meshed with the swing gear 791 to drive the nozzle 792 to swing upward, thereby increasing the coverage of the nozzle 792 and further improving the effect of the nozzle 792 in spraying the release agent.
