[0022] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0023] like Figures 1 to 5 , which is a schematic structural diagram of an automatic transfer device for pin molds provided by the present invention. The automatic transfer device for pin molds includes a turntable 10, a plurality of mold clamping devices 20 disposed on the turntable 10, and a drive mechanism 30 disposed on the turntable 10 facing away from the mold clamping devices 20. It is contemplated that the automatic transfer device for pin molds may also include other functional structures, such as fastening screws, drive belts, etc., which are well known to those skilled in the art and will not be further described here.

[0024] The turntable 10 includes a turntable body 11 and a rotation shaft hole 12 disposed in the middle area of ​​the turntable body 11 .

[0025] See also Figure 1 The two symmetrical ends of the turntable body 11 are arc-shaped, and the other two ends are parallel sides that intersect with the arcs on both sides.

[0026] The rotating shaft hole 12 is fixedly connected to the driving mechanism 30, so that the rotating disk 10 can rotate with the driving mechanism 30. A plurality of positioning holes 13 are arranged around the rotating shaft hole 12. The plurality of positioning holes 13 are arranged around the central axis of the rotating shaft hole 12, further fixing the rotating disk 10 and the driving mechanism 30, and preventing relative rotation between the rotating disk 10 and the driving mechanism 30.

[0027] The turntable body 11 is also symmetrically provided with at least one set of weight-reducing holes 14. The symmetrical arrangement of the weight-reducing holes 14 ensures the balance of the turntable body 11 during rotation and evenly distributes the load after the mold clamping device 20 is installed, reducing stress concentration, thereby reducing the weight of the turntable body 11 and the load on the drive mechanism 30.

[0028] The mold clamping device 20 and the turntable body 11 can be fixed by pin insertion, so as to achieve the purpose of quick disassembly and assembly.

[0029] The mold clamping device 20 includes a base plate 21, two mold plug-in parts 22 arranged near one end of the base plate 21, two first cylinders 23 arranged on the other end of the base plate 21, and two second cylinders 24 arranged on the end surface of the mold plug-in part 22 facing away from the first cylinders 23.

[0030] The end of the bottom plate 21 away from the mold plug-in part 22 is screwed to the turntable body 11 and fixed at the corner of the turntable body 11, so that the weight is evenly distributed and it is convenient for a robot arm (not shown) to grab it. The bottom plate 21 includes a bottom plate body 211, and two blocks 212 are provided at one end near the end of the two mold plug-in parts 22. The outer contour of the two blocks 212 is "U"-shaped, which is used to reduce weight. The end faces of the two blocks 211 facing the mold plug-in part 22 are flush with the end face adjacent to the mold plug-in part 22, which plays a role in quickly positioning the mold.

[0031] The mold plug-in portion 22 is used to plug in the mold, so that a robot arm (not shown) can grab the mold clamping device 20, thereby being able to load at least two molds at a time, thereby improving production efficiency.

[0032] The mold inserting portion 22 includes a mold platform 221 and an avoidance hole 222 provided on one side of the mold platform 221. The mold platform 221 is used to prevent the mold, and the avoidance hole 222 is used to cooperate with the second cylinder 24, which will be described below in conjunction with the second cylinder 24.

[0033] The number of the first cylinders 23 and the second cylinders 24 corresponds to the number of the mold inserting parts 22, so that each mold inserting part 22 corresponds to one first cylinder 23 and one second cylinder 24. The movable ends of the two first cylinders 23 are arranged toward the mold inserting part 22. Figure 4 The two second cylinders 24 are arranged toward the same side to improve space utilization. The first cylinder 23 and the second cylinder 24 are both driven by an external air pump, which is a prior art and will not be described in detail here.

[0034] The movable end of the first cylinder 23 is provided with a claw 231 for securing the mold. The movable end of the second cylinder 24 is provided with a pressure plate 241. One end of the pressure plate 241 extends from the escape hole 222 to the other end surface of the base plate 21. Driven by the second cylinder 24, the pressure plate 241 presses against one end surface of the mold. It is conceivable that the thickness of the pressure plate 241 is smaller than the width of the escape hole 222, ensuring that the pressure plate 241 can reciprocate within the escape hole 222.

[0035] Two cylinder slots 25 are spaced apart on one end of the base plate 21, away from the mold insertion portion 22. The two first cylinders 23 are inserted into these cylinder slots 25, respectively. These cylinder slots 25 and the mold platform 221 are coaxially aligned. This ensures that when the first cylinders 23 are inserted into these cylinder slots 25, they are aligned with the mold platform 221, ensuring a balanced force applied to the mold by the claws 231 of the first cylinders 23 when the mold is secured.

[0036] The drive mechanism 30 includes a rotating shaft assembly 31 and a drive motor 32 that drives the rotating shaft assembly 31. The output shaft of the rotating shaft assembly 31 is fixed to the rotating shaft hole 12 and the positioning hole 13. The drive motor 32 is connected to the rotating shaft assembly 31 via a gear or belt transmission, thereby driving the rotating shaft assembly 31 and the turntable 10 to rotate. The rotating shaft assembly 31 and the drive motor 32 are conventional and will not be described in detail here.

[0037] During use, the robotic arm places the mold onto the mold platform 221. The movable end of the first cylinder 23 moves toward the mold to engage it. The movable end of the second cylinder 24 contacts the side of the mold, cooperating with the mold platform 221 to clamp the mold, thus securing the mold. Next, the drive mechanism 30 rotates the turntable 10, proceeding to the next assembly step between the base plate 21 and the mold. The angular changes in the mold clamping device 20 caused by the rotation of the turntable 10 can be compensated for by a multi-axis robotic arm, which is a prior art and will not be further described here.

[0038] Compared to the prior art, the present invention provides an automatic transfer device for stitch molds. By connecting a turntable 10 to a drive mechanism 30 and installing at least two sets of mold clamping devices 20 on the turntable 10, the device can rapidly transport molds by rotating the turntable 10. The mold platform 221, the avoidance hole 222, the first cylinder 23, and the second cylinder 24 are located on the base plate 21. The first and second cylinders 23, 24 clamp the molds to the mold platform 221, allowing them to be secured to the mold platform 221 without the use of fasteners. This facilitates assembly and disassembly, resulting in high practicality.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
