Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts processing, and particularly to a device for removing injection-molded automotive interior parts. Background Art

[0002] As a part of an automobile, automotive interior parts usually use plastic materials with strong stability, good structural performance and light weight to reduce the load-bearing weight. Some existing automotive interior part productions adopt an injection molding process, in which thermoplastic or thermosetting plastics are injected into a molding die by an injection molding machine to make various-shaped automotive interior parts; after the injection-molded product is formed, it needs to be removed. Some existing removal methods of injection molding machines are to manually remove the parts, that is, to take out the processed injection-molded products in the die and then carry out the injection molding work of the next product. However, when manually taking the materials, not only is it easy to be scalded by the injection-molded workpieces, but also the picking efficiency is relatively low; some are to clamp the injection molding machine products by a manipulator. If the clamping force is too large, the injection-molded parts will be damaged, and if the clamping force is too small, they cannot be firmly clamped, resulting in poor clamping stability of the injection-molded products; especially when the injection-molded parts are ejected by the demolding mechanism in the die, if the existing manipulator cannot clamp the injection-molded parts in time, it will directly cause the injection-molded parts to fall and be damaged; and during the transfer of the injection-molded parts, shaking will inevitably occur, which also causes the injection-molded parts to fall, which is not conducive to actual use.

[0015] The beneficial effects of the present invention are as follows: 1.

At this time, drive the positioning mechanism to move through the unlocking mechanism, so that the positioning mechanism releases the lock on the smooth rod. Under the action of the elastic force of the return spring, the movable support seat drives the smooth rod to move forward for resetting. The smooth rod drives the drawing gas mechanism to move back for resetting, so that the drawing gas mechanism pushes the gas into the suction cup, making the suction cup release the adsorption of the injection-molded product, and the injection-molded product falls downward onto the blanking table, completing the process of taking out the injection-molded product from the mold.

[0017] 3. By separating the locking crown gear in the locking mechanism from the rotating crown gear, the rotating arm can rotate along the axis of the rotating shaft at this time, so as to adjust the position of the rotating arm. When the rotating arm rotates, it drives the adsorption mechanism to move, thereby changing the adsorption position of the adsorption mechanism, so that the adsorption mechanism can adsorb and connect products of different shapes; by screwing the locking nut outwards along the positioning column to separate the locking nut from the side surface of the rotating arm, the positioning column can be pushed to drive the positioning ring, positioning sleeve, air duct and suction cup to move synchronously at this time, so as to adjust the position of the suction cup, so that the suction cup can adsorb injection molded products of different shapes, greatly improving the applicable range of the taking-out device.

[0020] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the drawings of the specification. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 11 , the present invention provides a technical solution: a device for taking out automotive interior parts during injection molding, including a three-axis linear module 1. A vertical plate 11 is fixedly installed on the side of the slide of the three-axis linear module 1. The vertical plate 11 is fixedly installed on the slide of the Z-axis linear module in the three-axis linear module 1. The lower end of the vertical plate 11 is fixedly connected to a connecting seat 2. A plurality of round holes 21 are arranged in an annular array on the side of the connecting seat 2. An activity support seat 3 is arranged on one side of the connecting seat 2. A plurality of smooth rods 35 are fixedly connected in an annular array on the side of the activity support seat 3 close to the connecting seat 2. A return spring 37 is sleeved on each smooth rod 35. A plurality of card slots 36 are equidistantly arranged on the side of each smooth rod 35. One end of each smooth rod 35 passes through a corresponding round hole 21 and is fixedly sleeved with a limiting ring. The smooth rod 35 is slidably connected to the round hole 21. The two ends of the return spring 37 are respectively abutted against the connecting seat 2 and the activity support seat 3; The cylindrical surface of the movable support base 3 is provided with an annular groove 31. A plurality of rotating arms 4 are rotatably installed symmetrically left and right in the annular groove 31. A locking mechanism for fixing the rotating arms 4 is installed on one side of the movable support base 3 close to the connecting seat 2. Two adsorption mechanisms are installed on the rotating arms 4. The number of adsorption mechanisms on the rotating arms 4 can be increased or decreased according to needs. A positioning mechanism for locking the optical rod 35 is installed inside the round hole 21. A pulling gas mechanism is installed on one side of the connecting seat 2 away from the movable support base 3. The pulling gas mechanism is connected to the adsorption mechanism through a hose 67.

[0022] Please refer to Figure 3 、 Figures 8 to 10 , one end of the rotating arm 4 located in the annular groove 31 is fixedly inserted with a rotating shaft 44. The rotating arm 4 is rotatably connected to the movable support base 3 through the rotating shaft 44. The rotating arm 4 is in sliding contact with the annular groove 31. One end of the rotating shaft 44 passes through the movable support base 3 and extends to the outside and is connected to the rotating crown gear 45. The locking mechanism is arranged on the side of the rotating crown gear 45.

[0023] A plurality of fan-shaped grooves 32 are arranged in an annular array on the front and rear inner side walls of the annular groove 31. Fan-shaped blocks 43 are symmetrically and fixedly connected to the front and rear sides of the rotating arm 4. The fan-shaped blocks 43 are in sliding connection with the adjacent fan-shaped grooves 32.

[0024] When the rotating arm 4 rotates, it rotates around the axis line of the rotating shaft 44. When the rotating arm 4 rotates, it drives the fan-shaped block 43 to rotate along the fan-shaped groove 32, so that the rotating arm 4 can rotate stably.

[0025] The locking mechanism includes a threaded column 33 fixedly connected to one side of the movable support base 3 close to the connecting seat 2. Limiting plates 34 are symmetrically and fixedly connected to the upper and lower sides of the side surface of the movable support base 3 near the threaded column 33. A transmission plate 5 is slidably connected back and forth between the two limiting plates 34. A circular groove 51 is formed through the side surface of the transmission plate 5. A plurality of locking crown gears 52 are symmetrically and fixedly connected to one side of the transmission plate 5 close to the movable support base 3. The locking crown gears 52 are engaged with the rotating crown gear 45. An internal threaded sleeve 53 is movably inserted into the circular groove 51. The internal threaded sleeve 53 is sleeved on the threaded column 33. Annular seats 54 and adjusting sleeves 55 are respectively fixedly sleeved on both ends of the internal threaded sleeve 53. The annular seats 54 and the adjusting sleeves 55 are respectively in contact with both sides of the transmission plate 5.

[0026] Among them, the annular seat 54 is located on the side of the transmission plate 5 close to the movable support base 3, the adjusting sleeve 55 is arranged on the side of the transmission plate 5 away from the movable support base 3, and both the annular seat 54 and the adjusting sleeve 55 are in rotational contact with the transmission plate 5; By rotating the adjusting sleeve 55, the internal threaded sleeve 53 is driven to rotate along the circular groove 51. By setting the annular seat 54 and the adjusting sleeve 55 to cooperate to limit the position of the internal threaded sleeve 53, the internal threaded sleeve 53 can rotate stably along the circular groove 51.

[0027] Both the upper and lower sides of the transmission plate 5 are symmetrically provided with grooves, the limiting plate 34 is slidably connected to the grooves, and the internally threaded sleeve 53 is threadedly connected to the threaded column 33.

[0028] When the internally threaded sleeve 53 rotates, it will move back and forth along the threaded column 33. At the same time, the internally threaded sleeve 53 drives the annular seat 54 and the adjusting sleeve 55 to move. The transmission plate 5 is driven to move back and forth through the annular seat 54 and the adjusting sleeve 55. During the process of the transmission plate 5 moving back and forth, it slides along the limiting plate 34, so that the transmission plate 5 can move stably; In this application document, the side of the movable support seat 3 away from the connecting seat 2 is defined as the front side; When the transmission plate 5 moves forward, the transmission plate 5 drives the locking crown gear 52 to engage with the rotating crown gear 45, thereby locking the rotating crown gear 45, making the rotating shaft 44 and the rotating arm 4 unable to rotate, and further realizing the locking of the rotating arm 4; When the transmission plate 5 moves backward, the transmission plate 5 drives the locking crown gear 52 to separate from the rotating crown gear 45. At this time, the rotating crown gear 45 can rotate freely, enabling the rotating arm 4 to rotate along the axis of the rotating shaft 44, thereby adjusting the position of the rotating arm 4. When the rotating arm 4 rotates, it drives the adsorption mechanism to move, thereby changing the adsorption position of the adsorption mechanism, so that the adsorption mechanism can perform adsorption connection on products of different shapes.

[0029] Please refer to Figure 4 、 Figure 5 、 Figures 8 to 11 , a mounting groove 41 is penetrated through the side surface of the rotating arm 4. Guide grooves 42 are symmetrically provided on both inner side walls of the mounting groove 41. The adsorption mechanism includes a positioning column 6 movably installed in the mounting groove 41. One end of the positioning column 6 is provided with an external thread, the other end of the positioning column 6 is fixedly sleeved with a positioning ring 62. A locking nut 63 is threadedly connected to the end of the positioning column 6 provided with the external thread. A positioning sleeve 64 is fixedly connected to the side surface of the positioning ring 62. A through hole is penetrated through the positioning column 6, and an air duct 65 is penetrated and inserted into the through hole. One end of the air duct 65 extends into the inner cavity of the positioning sleeve 64. A suction cup 66 is fixedly sleeved at the end of the air duct 65 in the inner cavity of the positioning sleeve 64. The adsorption end of the suction cup 66 is outside the positioning sleeve 64, and there is a gap between the outside of the suction cup 66 and the positioning sleeve 64.

[0030] Guide blocks 61 are symmetrically and fixedly connected to the side surface of the positioning column 6. The guide blocks 61 are slidably connected to the guide grooves 42. The positioning ring 62 and the locking nut 63 are respectively located on both sides of the rotating arm 4.

[0031] The locking nut 63 abuts against the rotating arm 4. By providing the locking nut 63, the positioning column 6 can be locked in the mounting groove 41 of the rotating arm 4; When it is necessary to adjust the position of the positioning post 6, the locking nut 63 needs to be screwed outwards along the positioning post 6 first to separate the locking nut 63 from the side surface of the rotating arm 4. At this time, the positioning post 6 can be pushed to slide along the installation groove 41. At the same time, the positioning post 6 drives the guiding block 61 to slide along the guiding groove 42, so that the positioning post 6 can slide stably along the installation groove 41. When the positioning post 6 moves, it drives the positioning ring 62, the positioning sleeve 64, the air duct 65, and the suction cup 66 to move synchronously, thereby adjusting the position of the suction cup 66 so that the suction cup 66 can adsorb injection molded products of different shapes; When it is necessary to lock the positioning post 6, the locking nut 63 is screwed inwards along the positioning post 6 so that the side surface of the locking nut 63 abuts against the side surface of the rotating arm 4, so that the positioning post 6 is relatively fixed with the rotating arm 4. Furthermore, the positioning ring 62, the positioning sleeve 64, the air duct 65, and the suction cup 66 cannot move, completing the positioning of the suction cup 66.

[0032] Please refer to Figure 4 、 Figure 6 、 Figure 7 、and Figure 9 ., on the side of the round hole 21, there is an activity groove 22 opened. On the inner side wall of the activity groove 22, there are sliding grooves 23 symmetrically opened. The positioning mechanism includes an activity block 7 slidably installed in the activity groove 22. A contraction groove 71 is opened inside the activity block 7. On both sides of the activity block 7, there are sliding blocks 72 symmetrically fixed. The sliding blocks 72 are slidably connected with the sliding grooves 23. On the rear side surface of the activity block 7, there is a driving post 73 fixedly connected. A convex locking block 74 is slidably installed in the contraction groove 71. On one side of the convex locking block 74, there is an elastic sheet 75 fixedly installed. One side of the elastic sheet 75 abuts against the contraction groove 71. The protruding end of the convex locking block 74 passes through the contraction groove 71 and extends to the outside. The front side of the protruding end of the convex locking block 74 is a slope surface. The protruding end of the convex locking block 74 is clamped with the clamping groove 36. An unlocking mechanism is installed on the side surface of the connecting seat 2.

[0033] The elastic sheet 75 exerts an elastic force on the convex locking block 74. The convex locking block 74 is slidably connected with the activity block 7. Through the cooperation of the activity groove 22, the sliding groove 23, and the sliding block 72 provided, the activity block 7 can only slide along the activity groove 22.

[0034] The optical rod 35 is locked by the positioning mechanism provided. When the optical rod 35 slides backward along the round hole 21, during the movement of the optical rod 35, it will be in pressing contact with the slope surface of the protruding end of the convex locking block 74. The optical rod 35 pushes the convex locking block 74 to slide into the contraction groove 71. At this time, the convex locking block 74 presses the elastic sheet 75. Under the action of the elastic force of the elastic sheet 75, the convex locking block 74 always maintains a tendency to move outwards; When the card slot 36 on the side of the polished rod 35 moves to the position where it is aligned with the protruding end of the convex locking block 74, under the elastic force of the elastic piece 75, the protruding end of the convex locking block 74 is snapped into the card slot 36, preventing the polished rod 35 from moving back.

[0035] The unlocking mechanism includes a concave plate 8 fixedly installed on the side of the connecting seat 2 away from the movable support seat 3. A circular disc 81 is rotatably installed inside the concave plate 8. A plurality of inclined slots 82 are arranged in an annular array on the side of the circular disc 81. The number of inclined slots 82 is equal to the number of driving columns 73. The circular disc 81 is driven by the motor shaft of a servo motor fixedly installed on the concave plate 8. The driving columns 73 are inserted into the inclined slots 82 and are slidably connected to the inclined slots 82. The air pumping mechanism is installed on the concave plate 8.

[0036] By driving the circular disc 81 to rotate forward or backward through the motor shaft of the servo motor, when the circular disc 81 rotates, it drives the inclined slots 82 to rotate. At this time, the driving columns 73 slide along the inclined slots 82, and at the same time, the inclined slots 82 push the driving columns 73 to move, so that the driving columns 73 can reciprocate along the movable slots 22.

[0037] When the motor shaft of the servo motor drives the circular disc 81 to rotate forward, at this time, the inclined slots 82 on the circular disc 81 push the driving columns 73 to move inward along the movable slots 22. The driving columns 73 drive the movable blocks 7 to slide inward along the movable slots 22, and the movable blocks 7 drive the convex locking blocks 74 to move out of the card slots 36. When the motor shaft of the servo motor drives the circular disc 81 to rotate backward, at this time, the inclined slots 82 on the circular disc 81 push the driving columns 73 to move outward along the movable slots 22. The driving columns 73 drive the movable blocks 7 to slide outward along the movable slots 22, so as to reset the positioning mechanism.

[0038] Please refer to Figures 1 to 3 As shown in the figure, the air pumping mechanism includes an air cylinder 9 arranged on the side of the concave plate 8. The bottom of the air cylinder 9 is symmetrically and fixedly connected with L-shaped brackets 91. One end of the L-shaped brackets 91 is fixedly connected with the side of the concave plate 8. The open end of the air cylinder 9 is fixedly installed with a top cover 92. A piston rod 93 is slidably connected inside the top cover 92.

The end of the transmission rod 96 away from the cross-shaped frame 95 is fixedly connected with the polished rod 35.

[0039] One end of the hose 67 is fixedly connected to the side surface of the air cylinder 9, and the other end of the hose 67 is fixedly sleeved on the air duct 65. The air duct 65 is communicated with the inner cavity of the air cylinder 9 through the arranged hose 67; The piston seat 94 is driven by the piston rod 93 to slide outward along the inner cavity of the air cylinder 9. At this time, the piston seat 94 evacuates the gas in the suction cup 66 through the hose 67 and the air duct 65, so that the inner cavity of the suction cup 66 is in a negative pressure state, thereby enabling the suction cup 66 to firmly adsorb the injection molded product; The piston seat 94 is driven by the piston rod 93 to slide inward along the inner cavity of the air cylinder 9. At this time, the piston seat 94 pushes the gas in the inner cavity of the air cylinder 9 into the suction cup 66 through the hose 67 and the air duct 65, so that the suction cup 66 releases the adsorption of the injection molded product.

[0040] Working principle: When the automotive interior parts need to be taken out after injection molding, first open the mold, and then drive the taking-out device to move through the three-axis linear module 1, so that the suction cup 66 in the taking-out device is closely attached to the side surface of the injection molded product. At this time, the injection molded product is pushed outward along the mold cavity by the ejection mechanism in the mold for demolding; During the movement of the injection molded product, the suction cup 66 is first pushed to deform. When the suction cup 66 deforms to a certain extent, one end of the side surface of the suction cup 66 abuts against the positioning sleeve 64. At this time, the injection molded product continues to move outward along the mold cavity. The injection molded product drives the positioning sleeve 64 to move synchronously through the suction cup 66. The positioning sleeve 64 drives the positioning ring 62 and the rotating arm 4 to move synchronously. The rotating arm 4 drives the movable support seat 3 to move synchronously. The movable support seat 3 drives the optical rod 35 to move, so that the optical rod 35 slides backward along the circular hole 21. At this time, the movable support seat 3 presses the return spring 37.

[0041] During the backward movement of the optical rod 35, the cross-shaped frame 95 is driven to move backward through the transmission rod 96. The cross-shaped frame 95 drives the piston seat 94 to slide outward along the inner cavity of the air cylinder 9 through the piston rod 93. At this time, the piston seat 94 evacuates the gas in the suction cup 66 through the hose 67 and the air duct 65, so that the inner cavity of the suction cup 66 is in a negative pressure state, thereby enabling the suction cup 66 to firmly adsorb the injection molded product. When the injection molded product is removed from the mold cavity, the suction cup 66 can continuously adsorb and fix the injection molded product to prevent the injection molded product from falling downward.

[0042] When the optical rod 35 slides backward along the circular hole 21, the convex locking block 74 will be pushed to slide into the contraction groove 71 during the movement of the optical rod 35. At this time, the convex locking block 74 presses the elastic piece 75, and under the elastic force of the elastic piece 75, the convex locking block 74 always maintains a tendency to move outward; When the injection molded product stops moving after being removed from the mold cavity, at this time, the polished rod 35 stops moving, and the card slot 36 on the side of the polished rod 35 moves to the position aligned with the protruding end of the convex locking block 74. Under the elastic force of the elastic piece 75, the protruding end of the convex locking block 74 is snapped into the card slot 36 to lock the polished rod 35, making the polished rod 35 unable to move back, that is, the polished rod 35 cannot move forward. At this time, the return spring 37 is in a compressed state, causing the movable support seat 3 to maintain a tendency to move forward.

[0043] Then, the three-axis linear module 1 drives the taking-out device to move. The suction cup 66 in the taking-out device drives the injection molded product to move, and transfers the injection molded product to the upper end of the blanking table. At this time, when the motor shaft of the servo motor drives the circular disk 81 to rotate forward, the inclined groove 82 on the circular disk 81 pushes the driving column 73 to move inward along the movable groove 22. The driving column 73 drives the movable block 7 to slide inward along the movable groove 22. The movable block 7 drives the convex locking block 74 to move out of the card slot 36, releasing the locking of the positioning mechanism on the polished rod 35. Under the elastic force of the return spring 37, the movable support seat 3 drives the polished rod 35 to move forward for resetting.

[0044] During the forward movement of the polished rod 35, it drives the transmission rod 96 to move forward. The transmission rod 96 drives the cross-shaped frame 95 to move forward. At this time, the cross-shaped frame 95 drives the piston seat 94 to slide inward along the inner cavity of the air cylinder 9 through the piston rod 93. At this time, the piston seat 94 pushes the gas in the inner cavity of the air cylinder 9 into the suction cup 66 through the hose 67 and the air guide pipe 65, causing the suction cup 66 to release the adsorption of the injection molded product, and the injection molded product drops downward onto the blanking table, completing the process of taking out the injection molded product from the mold.

[0045] Then, the motor shaft of the servo motor drives the circular disk 81 to rotate in reverse. At this time, the inclined groove 82 on the circular disk 81 pushes the driving column 73 to move outward along the movable groove 22. The driving column 73 drives the movable block 7 to slide outward along the movable groove 22, thereby resetting the positioning mechanism.

[0046] By rotating the adjusting sleeve 55, the internal thread sleeve 53 moves backward along the threaded column 33. The internal thread sleeve 53 drives the transmission plate 5 to move backward through the cooperation of the annular seat 54 and the adjusting sleeve 55. The transmission plate 5 drives the locking crown gear 52 to separate from the rotating crown gear 45. At this time, the rotating arm 4 can rotate along the axis of the rotating shaft 44, thereby adjusting the position of the rotating arm 4. When the rotating arm 4 rotates, it drives the adsorption mechanism to move, thereby changing the adsorption position of the adsorption mechanism, enabling the adsorption mechanism to adsorb and connect products of different shapes. After the adjustment is completed, rotate the adjusting sleeve 55 in the reverse direction, and the transmission plate 5 drives the locking crown gear 52 to engage with the rotating crown gear 45, thereby locking the rotating crown gear 45, making the rotating shaft 44 and the rotating arm 4 unable to rotate, and further realizing the locking of the rotating arm 4.

[0047] By screwing out the locking nut 63 along the positioning post 6 to separate the locking nut 63 from the side surface of the rotating arm 4, at this time, it is possible to push the positioning post 6 to drive the positioning ring 62, the positioning sleeve 64, the air duct 65, and the suction cup 66 to move synchronously, thereby adjusting the position of the suction cup 66 so that the suction cup 66 can adsorb injection molded products of different shapes, greatly improving the applicable range of the taking-out device; When it is necessary to lock the positioning post 6, screw the locking nut 63 along the positioning post 6 inward so that the side surface of the locking nut 63 abuts against the side surface of the rotating arm 4, thereby relatively fixing the positioning post 6 and the rotating arm 4, and further making the positioning ring 62, the positioning sleeve 64, the air duct 65, and the suction cup 66 unable to move, completing the positioning of the suction cup 66.
