[0033] A preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0034] See also Figures 1 to 8 The present invention provides an automatic nail embedding and removing device for an injection mold, comprising: a workbench 8, a feeding device, a transfer mechanism, a manipulator and a nail embedding and removing mechanism. The feeding device and the transfer mechanism are both installed on the workbench 8. The manipulator can be arranged between the workbench 8 and the injection mold. The nail embedding and removing mechanism is installed on the manipulator, and the manipulator is used to drive the nail embedding and removing mechanism to reciprocate between the workbench 8 and the injection mold.

[0035] The feeding device comprises a vibration plate 1 and a discharging module, wherein the vibration plate 1 is used to transport a plurality of embedded nails 2 to the discharging module in an orderly and directional arrangement.

[0036] It should be noted that the vibration plate 1 adopts the existing conventional technology, and its specific structural principle of orderly directional arrangement of the embedded nails 2 is the same as that of the existing technology, so it will not be elaborated on. The embedded nail 2 in this embodiment is cylindrical, and one end of the embedded nail 2 has a small protrusion, and the diameter of the small protrusion is smaller than the diameter of the body of the embedded nail 2. The vibration plate 1 conveys the embedded nail 2 to the discharging module in the direction where the small protrusion is upward.

[0037] Furthermore, the transfer mechanism includes a linear module 3 and a loading platform 4 installed on the linear module 3. The transfer mechanism is also provided with a loading station and a picking station. The linear module 3 is used to drive the loading platform 4 to reciprocate between the loading station and the picking station. The loading platform 4 can receive the embedded nails 2 dropped one by one by the discharging module at the loading station.

[0038] Furthermore, the nail embedding and extracting mechanism includes a nail embedding module and an extracting module, and the nail embedding module includes a nail extracting cylinder 5, a push rod 6 and a nail pushing power device. The interior of the nail extracting cylinder 5 is provided with a central hole 501 passing through both ends thereof, so as to Figure 8 For reference, in the present embodiment, the inner diameter of the upper section of the center hole 501 matches the outer diameter of the push rod 6, and the push rod 6 is slidably inserted into the center hole 501 from the upper end of the nail removal tube 5; the inner diameter of the lower section of the center hole 501 is slightly larger than the outer diameter of the embedded nail 2, and in the reset state, the lower end of the push rod 6 does not extend to the bottom of the nail removal tube 5, that is, the bottom surface of the push rod 6 is higher than the bottom surface of the nail removal tube 5, and the portion of the center hole 501 not inserted by the push rod 6 (that is, the portion of the center hole 501 below the push rod 6) can be used for the embedded nail 2 to be inserted.

[0039] It is worth mentioning that the push rod 6 is provided with an air suction hole 601, the upper end of the air suction hole 601 is connected to a vacuum pump through a gas pipeline, and the orifice of the air suction hole 601 is located at the bottom of the push rod 6. The embedded nail 2 can be sucked by the air suction hole 601 while being inserted from the lower end of the nail extraction tube 5, thereby achieving stable grasping of the nail extraction tube 5. The upper end of the push rod 6 is fixedly connected to a nail pushing power device, which is used to drive the push rod 6 to push the embedded nail 2 out of the nail extraction tube 5.

[0040] In the present invention, the manipulator is used to drive the nail embedding module to take the embedded nails 2 on the loading platform 4 at the material taking station and place them into the injection mold. The manipulator is also used to drive the part taking module to take out the injection molded product from the injection mold.

[0041] The present invention integrates the automatic nail embedding and pickup functions into one, and the nail embedding and pickup mechanism is driven by a manipulator to move, and the embedded nail 2 is first embedded into the front mold of the injection mold by the nail embedding module, and then the manipulator drives the embedded nail pickup mechanism to move to the rear mold of the injection mold, and the product ejected from the rear mold is taken away by the pickup module, so as to realize the automatic operation of front mold nail embedding and rear mold pickup, which greatly improves the production efficiency, reduces the labor intensity, and realizes continuous production. At the same time, the present invention relies on the vibration plate 1 to cooperate with the discharging module to realize the orderly feeding of the embedded nail 2, and transfers the embedded nail 2 through the transfer mechanism to facilitate the embedding module to pick up the material. The embedding module stably grabs the embedded nail 2 through the nail picking tube 5 and the push rod 6, so as to realize non-destructive picking, effectively avoid damage to the embedded nail 2 during the embedding process, and finally, in the process of placing the embedded nail 2 into the injection mold, the push rod 6 is driven by the nail pushing power device to push the embedded nail 2 out of the nail picking tube 5, so as to ensure the accuracy of the embedded nail position and the consistency of the embedded nail depth, and effectively improve the product quality. In addition, the entire device has a compact structure, is easy to operate, has strong adaptability, and can be widely used in various injection mold production occasions.

[0042] See also Figure 1 and Figure 2 The vibration plate 1 is mounted on the top of the workbench 8 through the profile, the discharging module and the linear module 3 are both installed on the table top of the workbench 8, and the discharging module is mounted above the linear module 3 through the bracket 9, so that the discharging module can put the embedded nails 2 into the loading platform 4.

[0043] The discharge module includes a storage barrel 10 fixed on the bracket 9 in the vertical direction. The storage barrel 10 is a hollow cylindrical shape, which is used to accommodate the embedded nails 2 transported by the vibration plate 1. The upper and lower ends of the storage barrel 10 are respectively provided with a feed port and a discharge port. The feed port is connected to the vibration plate 1 through a pipeline, and the discharge port is used for the embedded nails 2 to fall. The vibration plate 1 transports the embedded nails 2 into the storage barrel 10 through the pipeline through the feed port, and the embedded nails 2 are arranged and distributed in the storage barrel 10 in the vertical direction.

[0044] See also Figure 3 The discharging module further includes two material blocking mechanisms located beside the storage barrel 10. The two material blocking mechanisms are both mounted on the bracket 9 in the horizontal direction and are spaced apart from each other. The two material blocking mechanisms each include a first cylinder 11 and a material blocking rod 12 mounted on the first cylinder 11. The storage barrel 10 is provided with two material blocking holes 1001 corresponding to the two material blocking rods 12 in the radial direction. The two first cylinders 11 are used to drive their respective material blocking rods 12 to extend from the corresponding material blocking holes 1001 into the storage barrel 10 to stop the embedded nails 2.

[0045] In this embodiment, the first cylinder 11 may specifically be a pen-shaped cylinder.

[0046] See also Figure 4The top of the loading platform 4 is provided with a positioning hole 401 for receiving the embedded nails 2 dropped by the discharging module.

[0047] At the same time, a first cylinder 11 at the bottom drives the material blocking rod 12 thereon to retract, so that the lowest embedded nail 2 in the storage barrel 10 falls downward into the positioning hole 401 of the loading platform 4 due to its own gravity. Then, a first cylinder 11 at the bottom drives the material blocking rod 12 thereon to extend, and another first cylinder 11 at the top drives the material blocking rod 12 thereon to retract, and the operation is repeated in this way to realize the placement of the embedded nails 2 one by one.

[0048] The bracket 9 is also provided with a photoelectric sensor 13 for detecting the embedded nails 2 falling from the discharge port, which can detect whether any embedded nails 2 have fallen to avoid missing embedded nails.

[0049] like Figure 5 As shown, the loading platform 4 is also provided with a blowing port 402 at the bottom of the positioning hole 401, and the blowing port 402 is connected to the air compressor through a gas pipeline. Since the embedded nail 2 is a metal part with a certain weight, when the manipulator drives the embedded nail taking mechanism to take the embedded nail 2 from the loading platform 4, the embedded nail 2 is inserted from the lower end of the nail taking tube 5, and the top of the embedded nail 2 is not able to completely contact with the suction hole 601 of the push rod 6. The suction force is small due to the gap between the two, so it is impossible to ensure that the embedded nail 2 can be taken from the loading platform 4 by relying on the suction force of the suction hole 601 every time. The present invention is also provided with a blowing port 402 at the bottom of the positioning hole 401. When the nail taking tube 5 cooperates with the push rod 6 to absorb the embedded nail 2, the embedded nail 2 is blown upward through the blowing port 402, thereby ensuring that the suction hole 601 of the push rod 6 can absorb the embedded nail 2, thereby improving stability and reliability.

[0050] See also Figure 6 and Figure 7The nail embedding and extracting mechanism also includes a cylinder mounting plate 14 and a fixed plate 15, and the cylinder mounting plate 14 and the fixed plate 15 are fixedly connected by a plurality of connecting columns. The nail extracting barrel 5 is fixed on the fixed plate 15, and the nail pushing power device includes a second cylinder 7, which is fixed on the cylinder mounting plate 14, and a lifting plate 16 is fixedly connected to the output end of the second cylinder 7, and the lifting plate 16 is located between the cylinder mounting plate 14 and the fixed plate 15. The push rod 6 is fixed on the lifting plate 16. When the second cylinder 7 drives the lifting plate 16 to move, it can synchronously drive the push rod 6 to slide in the nail extracting barrel 5.

[0051] In addition, the fixing plate 15 is also provided with but not limited to two positioning posts 19 , which are used to cooperate with two positioning grooves provided on the front mold of the injection mold for positioning to ensure the accuracy of the embedded position of the embedded nail 2 .

[0052] like Figure 6 As shown, the pick-up module of the present invention includes a rotary cylinder 17 and two vacuum suction cups 18, the rotary cylinder 17 is fixed on the cylinder mounting plate 14, and the two vacuum suction cups 18 are mounted on the rotary cylinder 17. In the process of taking out the product, the rotary cylinder 17 drives the vacuum suction cups 18 to rotate 90 degrees, so that the two vacuum suction cups 18 are opposite to the back mold of the injection mold, so as to facilitate taking out the product; after the manipulator drives the nail embedding and picking mechanism to leave the injection mold, the rotary cylinder 17 drives the vacuum suction cups 18 to rotate 90 degrees in the opposite direction to reset, so as to facilitate placing the product on the subsequent station.

[0053] In the present invention, the linear module 3 adopts any one of a ball screw linear module, a synchronous belt linear module, a linear motor module, and a gear rack linear module. In this embodiment, a ball screw linear module is preferred; the manipulator adopts a five-axis manipulator or a six-axis manipulator. In this embodiment, a five-axis manipulator is preferred to reduce costs.

[0054] In this embodiment, two storage barrels 10 are provided and distributed side by side, and four positioning holes on the loading platform 4 are provided and distributed in a rectangular shape. Correspondingly, the nail embedding module is provided with four nail removal barrels 5 and four push rods 6. The four nail removal barrels 5 are all fixedly mounted on the fixed plate 15, and the four push rods 6 are all fixedly mounted on the lifting plate 16 and are slidably inserted into the four nail removal barrels 5 one by one, and the four push rods 6 are synchronously driven by the second cylinder 7, so that four embedded nails 2 can be embedded in the injection mold at one time.

[0055] The working principle of the automatic nail embedding and removal device for injection molds of the present invention is as follows: the embedded nails 2 are poured into the vibration plate 1, and the vibration plate 1 automatically arranges the embedded nails 2 in an orderly and directional manner and transports them to the two storage barrels 10; the linear module 3 drives the loading platform 4 to move to the loading station, so that two of the positioning holes 401 on the loading platform 4 are directly opposite to the discharge ports of the two storage barrels 10; then the blocking mechanisms on the sides of the two storage barrels 10 start to move, and each of them puts one embedded nail 2 into the positioning hole 401 below; thereafter, the linear module 3 drives the loading platform 4 to move again, so that the other two positioning holes 401 on the loading platform 4 are directly opposite to the discharge ports of the two storage barrels 10, and the embedded nails 2 are also put into these two positioning holes 401; then the linear module 3 drives the loading platform 4 to carry the four embedded nails 2 to return to the removal station. The robot drives the nail embedding and picking mechanism to move to the picking station. As the nail embedding and picking mechanism moves downward, the four embedded nails 2 on the loading platform 4 are inserted from the lower ends of the four nail picking tubes 5 respectively, and the suction hole 601 of the push rod 6 starts to absorb air. At the same time, the blowing port 402 on the loading platform 4 starts to blow air, so that the suction hole 601 of the push rod 6 can adsorb the embedded nails 2; next, the robot drives the nail embedding and picking mechanism to move between the front mold and the back mold of the injection mold, so that the four embedded nails 2 are aligned with the embedded positions of the front mold, and move toward the front mold to place the embedded nails 2 in the front mold, and then the second cylinder 7 drives the lifting plate 16 to drive the push rod 6 to push the embedded nails 2 out of the nail picking tube 5, and at the same time, the suction hole 601 of the push rod 6 stops absorbing air to complete the embedding. After the pre-embedding is completed, the rotary cylinder 17 drives the vacuum suction cup 18 to rotate 90°, so that the two vacuum suction cups 18 are opposite to the back mold of the injection mold, and the robot drives the nail embedding and removing mechanism to move toward the back mold, and the product ejected from the back mold is removed by the vacuum suction cup 18.

[0056] It can be seen that the automatic nail embedding and picking device for injection molds of the present invention integrates the automatic nail embedding and picking functions into one, and the nail embedding and picking mechanism is driven by a robot to move, and the embedded nails 2 are first embedded in the front mold of the injection mold through the nail embedding module, and then the robot drives the nail embedding and picking mechanism to move to the rear mold of the injection mold, and the product ejected from the rear mold is taken away by the picking module, thereby realizing the automated operation of front mold nail embedding and rear mold picking, which greatly improves production efficiency, reduces labor intensity, and realizes continuous production. At the same time, the present invention relies on the vibration plate 1 to cooperate with the discharging module to realize the orderly feeding of the embedded nails 2, and transfers the embedded nails 2 through the transfer mechanism to facilitate the embedding module to take the material. The embedding module absorbs and grabs the embedded nails 2 through the nail taking tube 5 and the push rod 6, which can improve the stability and reliability of taking away the embedded nails 2, and realize non-destructive material taking, effectively avoiding damage to the embedded nails 2 during the embedding process. In the process of placing the embedded nails 2 into the injection mold, the push rod 6 is driven by the nail pushing power device to push the embedded nails 2 out of the nail taking tube 5, ensuring the accuracy of the embedded nail position and the consistency of the embedded nail depth, and effectively improving the product quality. Further, the present invention is provided with a blowing port 402 at the bottom of the positioning hole 401 of the loading platform 4. When the nail taking tube 5 cooperates with the push rod 6 to absorb the embedded nail 2, the embedded nail 2 is blown up through the blowing port 402, thereby ensuring that the suction hole 601 of the push rod 6 can absorb the embedded nail 2, improving stability and reliability. In addition, the present invention has a compact overall structure, is easy to operate, and has strong adaptability, and can be widely used in various injection mold production occasions.
