Description

[Technical Field]

[0001] This invention relates to the field of automation mechanism technology, and in particular to a mechanism for embedding nuts in a two-color mold side slider. [Background Technology]

[0002] In two-color molds, nuts need to be embedded in the side slide of the mold core according to the production requirements of the product. However, multiple nuts need to be placed in the side slide in a single sequence, which leads to low automated production efficiency. When the robot places the nuts, it can only place one type of nut at a time, which makes the production cycle of the product longer. In addition, the placement of nuts at the back door of the two-color machine requires robotic equipment, which leads to high production costs and large space occupation.

[0003] In view of this, it is necessary to provide a mechanism for embedding nuts in the side slider of a two-color mold to solve the above problems. [Summary of the Invention]

[0004] The technical problem this invention aims to solve is as follows: In two-color molds, according to product production requirements, nuts need to be embedded in the side slides of the mold core. However, multiple nuts need to be placed sequentially into the side slides, resulting in low automated production efficiency. Furthermore, when a robot places the nuts, it can only place one type of nut at a time, leading to a longer production cycle. Additionally, placing the nuts at the rear door of the two-color mold requires robotic equipment, resulting in high production costs and a large space requirement. Therefore, this invention provides a nut embedding mechanism for the side slides of a two-color mold to solve the above problems.

[0005] The solution to the technical problem of this invention is: a mechanism for embedding a nut in a side slider of a two-color mold, comprising:

[0006] A fixed plate is fixedly connected to a nut-picking and placing device at one end and to a product-picking and placing device at the other end away from the nut-picking and placing device. The fixed plate is provided with connecting holes, and the fixed plate is fixedly connected to the moving end of the robot arm through the connecting holes.

[0007] The nut-picking and placing device includes a support frame for supporting the device. A first driving member is located on one side of the support frame. The first moving end of the first driving member is fixedly connected to a fixing assembly. The fixing assembly includes a connecting frame, a fixing frame, and a limiting plate. The connecting frame is fixedly connected to the first moving end of the first driving member, and the fixing frame is fixedly connected to the connecting frame. The fixing frame has an extension hole at the end where the nut is picked up. A sleeve is located on the side of the extension hole away from the nut. A stepped groove is located on the side of the sleeve that contacts the extension hole. The stepped groove is used to place the fixing nut. A push rod is movably located inside the sleeve. A connecting block is fixedly connected to the side of the push rod away from the stepped groove. A second driving member is fixedly connected to the limiting plate. The second moving end of the second driving member passes through the limiting plate and is fixedly connected to the connecting block.

A controller is provided on the side of the support plate with the first core pin. The controller is fixedly connected to the base and is used to control the sixth drive component.

[0009] Preferably, a slider mechanism is provided on one side of the first driving member. The slider mechanism includes a slider and a slide rail. The slider is fixedly connected to the support frame, and the slide rail is fixedly connected to the connecting frame. It serves as a guide when the first driving member controls the movement of the connecting frame.

[0010] Preferably, the fixing frame is provided with a first guide hole, and a guide sleeve is provided in the first guide hole. The support plate is fixedly connected to a first guide rod on the side where the first core pin is located. When the nut is picked up or removed, the first guide rod and the guide sleeve are slidably connected to provide guidance.

[0011] Preferably, the support frame is provided with a limiting member, which cooperates with the female mold core when the nut is placed to limit the displacement of the nut picking and placing device. The limiting member includes, but is not limited to, a limiting screw.

[0012] Preferably, a second guide rod is provided on the side of the nut-picking and placing device that contacts the female mold core, and a second guide hole is provided on the female mold core.

The first moving end of the first driving component is connected to a fixing assembly, and the second driving component is fixed within the fixing assembly. The second moving end of the second driving component is connected to a push rod inside the ejector sleeve. A sixth driving component is provided within the fixture assembly. When the nut-picking and placing device picks up a nut, the nut on the first core pin is pushed into the extension hole by a push plate on the sixth driving component. When the nut-picking and placing device places a nut, the first driving component causes the fixing assembly to move to the second core pin inside the side slider of the mold core, and then the second driving component causes the push rod to push the nut onto the second core pin. This mechanism can pick up multiple nuts of different models at once and place them on the side slider of the mold core, effectively improving automated production efficiency, shortening the product molding cycle, and saving costs and space by using a molding machine robotic arm.

The controller 407 is used to control the sixth drive member 404. When the nut pick-and-place device 200 touches the controller 407 while picking up the nut 20, the robot (not shown in the figure) drives the nut pick-and-place device 200 to stop moving. At the same time, the controller 407 controls the sixth moving end of the sixth drive member 404 to push the push plate 402, so that the push plate 402 pushes the nut 20 on the first core pin 406 into the extension hole 206 of the fixing frame 205. In this embodiment, the first core pin 406 is provided in five sets according to the number of nuts 20 in the molded product, and the sleeve 210 and the push rod 220 are provided in five sets according to the number of first core pins 406.

[0031] The support frame 201 is provided with a limiting member 270, which is used to limit the displacement of the nut picking and placing device 200 when the nut 20 is placed by the nut picking and placing device 200. The limiting member 270 cooperates with the female mold core 500 to limit the displacement of the nut picking and placing device 200. The limiting member 270 includes, but is not limited to, a limiting screw.

[0032] The nut-picking and placing device 200 is provided with a second guide rod 250 on the side that contacts the female mold core 500, and the female mold core 500 is provided with a second guide hole 501. When the nut-picking and placing device 200 places the nut 20, the second guide rod 250 and the second guide hole 501 are slidably connected to provide guidance.

[0033] The first drive component 202, the second drive component 230, and the sixth drive component 404 include, but are not limited to, cylinders.

[0034] The controller 407 includes, but is not limited to, limit switches.

[0035] The working process of this invention is as follows:

[0036] Nut 20 pick-up and place: The robot (not shown in the figure) drives the nut pick-up and place device 200 to move to the fixture assembly 400. Through the cooperation of the first guide rod 410 and the guide sleeve 241, the extension hole 206 of the nut pick-up and place device 200 is sleeved on the first core needle 406 of the fixture assembly 400. When the nut pick-up and place device 200 touches the controller 407, the robot (not shown in the figure) drives the nut pick-up and place device 200 to stop moving. At the same time, under the control of the controller 407, the sixth driving member 404 pushes the push plate 402 to move, so that the push plate 402 pushes the nut 20 on the first core needle 406 into the extension hole 206.

[0037] Nut Placement 20: The robotic arm (not shown in the figure) moves the nut placement device 200 away from the fixture assembly 400, and first moves the product placement device (not shown in the figure) to the male mold to grab the molded product after the injection molding is completed. Then, it moves the nut placement device 200 to the female mold core 500 of the female mold. Through the cooperation of the second guide rod 250 and the second guide hole 501, the position of the nut placement device 200 relative to the female mold core 500 is positioned. When the limiting member 270 in the nut placement device 200 touches the female mold core 500, the robotic arm (not shown in the figure) moves the nut placement device 200 to stop. At this time, the first moving end 203 of the first driving member 202 retracts inward and drives the fixing assembly 280, so that the extension hole 206 in the fixing frame 205 slides to the side. The second core pin 511 at end 510 moves, and then the second moving end 231 of the second drive member 230 controls the drive connecting block 235, so that the connecting block 235 drives the ejector rod 220 through the sleeve 210, pushing the nut 20 in the extension hole 206 onto the second core pin 511 of the side slider 510. Then, the first moving end 203 of the first drive member 202 extends outward and drives the fixing component 280, so that the fixing component 280 moves away from the side slider 510. Then, the second moving end 231 of the second drive member 230 drives the ejector rod 220 back to its original position through the connecting block 235. Finally, the robot (not shown in the figure) drives the nut picking and placing device 200 away from the side slider 510 of the female mold core 500 and exits the mold. The molding machine rotates the male mold to close the mold and enter the next injection molding cycle.

[0038] The beneficial effect of this invention is that it provides a nut-embedded mechanism for a two-color mold side slider. This mechanism involves fixing a nut-picking / placing device 200 to the moving end of a robotic arm (not shown in the figure). The nut-picking / placing device 200 includes a first driving member 202 and a second driving member 230. The first moving end 203 of the first driving member 202 is connected to a fixing assembly 280. The second driving member 230 is fixed within the fixing assembly 280, and its second moving end 231 is connected to a push rod 220 within a sleeve 210. A sixth driving member 404 is provided within a fixture assembly 400. When the nut-picking / placing device 200 picks up the nut 20, the first core pin 40... Nut 20 on the 6 is pushed into extension hole 206 by push plate 402 on sixth drive member 404. When nut 20 is placed by nut pick-and-place device 200, the fixing component 280 is moved to the second core pin 511 in the side slider 510 of the female mold core 500 by first drive member 202. Then, the ejector rod 220 is pushed onto the second core pin 511 by second drive member 230. This mechanism can pick up multiple nuts 20 of different models at one time and place them on the side slider 510 of the female mold core 500, effectively improving the production efficiency of automation, shortening the product molding cycle, and saving cost and space by using molding machine robot (not shown in the figure).
