[0042] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0043] First, combine Figures 1 to 4 The invention provides a hexagonal wrench injection molding embedding tooling according to an embodiment of the invention, which is used for automatic embedding of hexagonal wrenches during injection molding and has a wide range of application scenarios.

[0044] like Figures 1 to 4 As shown, an embodiment of the utility model is an injection-molded embedded tooling for an hexagonal wrench, which comprises a housing 100, a rotating module 200, a loading platform 300, two loading racks, a lifting module, a pre-positioning module and a manipulator 700.

[0045] Specifically, the rotating module 200 is disposed on the top of the housing 100 to provide a rotational driving force. The rotating module 200 may be a rotating mechanism that provides a rotational driving force in the prior art.

[0046] Specifically, the loading platform 300 is arranged at the output end of the rotating module 200 and rotates driven by the rotating module 200. A loading station 301 and a preparation station 302 are provided on the loading platform 300. The preparation station 302 is a station for placing the hex wrench on the loading rack, and the loading station 301 is a station for taking out the hex wrench from the loading rack.

[0047] Specifically, two loading racks are respectively arranged on the loading station 301 and the preparation station 302 on the loading platform 300, and are used to stack the Allen wrenches. The two loading racks rotate with the rotation of the loading platform 300, thereby switching from the loading station 301 and the preparation station 302 respectively. Any loading rack includes: a plurality of positioning columns 401, a fixing frame 402 and a lifting plate 403. The bottom ends of the plurality of positioning columns 401 are connected to the loading platform 300, and the plurality of positioning columns 401 form two placement areas, which are used to stack the Allen wrenches; the fixing frame 402 is arranged on the top of the plurality of positioning columns 401 to ensure the stability of the top of the plurality of positioning columns 401; the lifting plate 403 is movably mounted on the plurality of positioning columns 401. By moving the lifting plate 403, the Allen wrenches in the placement area can be lifted one by one.

[0048] Furthermore, each loading rack also includes two first clearance slots 404 and four support columns 405. The two first clearance slots 404 are located on top of the lifting plate 403 to provide clearance space for the robot arm 700 to grab the last Allen wrench. The four support columns 405 are located on top of the loading platform 300 to support the lifting plate 403 when it is in its lowest position.

[0049] Specifically, the lifting module is connected to the housing 100 and is used to lift the hexagonal wrench on the loading rack at the loading station 301. The lifting module includes: four through holes 501, a motor belt transmission mechanism 502, two guide pillars 503, a movable plate 504, and two lifting pillars 505. Two of the through holes 501 are opened at the loading station 301 of the loading platform 300, and the other two through holes 501 are opened at the preparation station 302 of the loading platform 300; the motor belt transmission mechanism 502 is set on the housing 100; the two guide pillars 503 are set inside the housing 100; the movable plate 504 is mounted on the two guide pillars 503, and the movable plate 504 is connected to the belt of the motor belt transmission mechanism 502; the bottom ends of the two lifting pillars 505 are set on the movable plate 504, and the top ends of the two lifting pillars 505 pass through the housing 100 and correspond one-to-one to the two through holes 501 at the loading station 301. When the motor belt drive mechanism 502 is running, it drives the movable plate 504 to lift upward, thereby lifting the two lifting columns 505, passing through the two through holes 501 at the loading station 301, contacting the lifting plate 403, and then lifting the lifting plate 403 to realize the lifting of the hexagonal wrench.

[0050] Furthermore, the lifting module also includes two ejector pins 506 and two positioning holes 507. The two ejector pins 506 are located at the top of the two lifting columns 505, respectively; the two positioning holes 507 are respectively provided on either lifting plate 403. When the lifting columns 505 are lifted and contact the lifting plate 403, the two ejector pins 506 are first inserted into the two positioning holes 507, respectively, to achieve the lifting position and ensure the stability of the lifting movement.

[0051] Specifically, the pre-positioning module is mounted on the housing 100 and is used to pre-position the hexagonal wrench to be injected. The pre-positioning module comprises a bracket 601, two positioning brackets 602, and two positioning cylinders 603. The bracket 601 is mounted on the housing 100; the two positioning brackets 602 are mounted on top of the bracket 601, each with a positioning area; and the two positioning cylinders 603 are mounted on either side of the two positioning brackets 602.

[0052] Furthermore, the two positioning frames 602 are each provided with a second clearance groove 604 , which provides clearance space for the manipulator 700 to grab the hexagonal wrenches on the two positioning frames 602 .

[0053] Specifically, the robot 700 is located on the outside of the casing 100, and is used to grab the hex wrench on the loading rack located at the loading station 301 to the pre-positioning module for pre-positioning, and then grab the pre-positioned hex wrench to the external injection molding machine 900, take out the injected hex wrench, and bury the hex wrench to be injected into the external injection molding machine 900.

[0054] Furthermore, the present invention's hexagonal wrench injection molding tooling further includes a detection port 801 and a detector 802. The detection port 801 is located on one side of any mounting bracket 402; the detector 802 faces the detection port 801 on the mounting bracket 402 at the loading station 301. The detector 802 detects whether the hexagonal wrench has reached the gripping position of the robot arm 700.

[0055] When in use, the loading rack at the material preparation station 302 is filled with hexagonal wrenches, and then the loading platform 300 is rotated 180 degrees under the drive of the rotating module 200, and the loading rack at the material preparation station 301 is moved to the material preparation station 302 for loading, and the loading rack at the material preparation station 302 filled with hexagonal wrenches is rotated to the loading station 301 to prepare for loading;

[0056] The motor belt drive mechanism 502 is controlled to operate, driving the movable plate 504 to move upward, thereby lifting the two lifting columns 505, passing through the two through holes 501 at the loading station 301, contacting the lifting plate 403, and then lifting the lifting plate 403 to realize the lifting of the hexagonal wrenches one by one. When the detector 802 detects that the hexagonal wrenches are in place, the robot 700 grabs the hexagonal wrenches that are lifted into place one by one to the positioning area, and then the positioning cylinder 603 is operated to pre-position the hexagonal wrenches. Then the robot 700 grabs the pre-positioned hexagonal wrenches to the external injection molding machine 900, takes out the injected hexagonal wrenches, and buries the hexagonal wrenches to be injected into the external injection molding machine 900.

[0057] Above, refer to Figures 1 to 4 The present invention describes an injection molding and embedding tooling for hexagonal wrenches according to an embodiment of the invention, which significantly improves production efficiency, greatly saves labor costs, and effectively reduces the physical burden on workers. The tooling can automatically complete the continuous loading and precise embedding operations of the hexagonal wrenches, thereby greatly optimizing the production process and realizing efficient and low-cost intelligent manufacturing.
