[0025] Embodiment:

[0026] Please refer to Figure 1-8 , the present application provides a technical solution: a new type of full-automatic in-mold hardware transfer device, including a moving mold 1 and an ejection unit 3 connected inside the moving mold 1. A second mold core 4 is also fixedly connected inside the moving mold 1. An activity cavity 11 is opened inside the moving mold 1. The ejection unit 3 includes a mounting plate 32 movably connected inside the activity cavity 11, a ejector pin 33 inserted inside the mounting plate 32, and a top plate 31 fixedly connected to one side of the mounting plate 32 for limiting the ejector pin 33.

[0027] A transfer unit 6 is connected to the inner wall of the activity cavity 11. The transmission unit includes two cylinders 61 symmetrically fixedly connected inside the moving mold 1, a driving plate 62 movably sleeved on the outer surface of the ejector pin 33, a driving column 65 fixedly connected to one side of the driving plate 62, a guide rail plate 63 fixedly connected to the inner wall of the activity cavity 11, a material cavity 64 opened inside the guide rail plate 63, and a discharge port 67 communicated with the material cavity 64. The telescopic ends of the two cylinders 61 are fixedly connected to one side of the driving plate 62. A channel for conveying hardware is opened inside the moving mold 1. A guiding and discharging part 5 for conveying hardware is fixedly connected inside the second mold core 4 and is connected to the channel inside the moving mold 1.

[0028] By setting the above solution, when the injection molding is completed and the moving mold 1 and the fixed mold move apart, the ejection mechanism of the injection molding machine can push the top plate 31 in the direction of the mounting plate 32. The top plate 31 and the mounting plate 32 move simultaneously and drive the ejector pin 33 to move. The movement of the ejector pin 33 can eject the formed product in the second mold core 4. After the above actions are completed, the ejection mechanism of the injection molding machine can drive the top plate 31 and the mounting plate 32 to move, causing the ejector pin 33 to move in the direction of the top plate 31. One end of the ejector pin 33 retracts into the second mold core 4. Then, the ejection mechanism of the injection molding machine closes the moving mold 1 and the fixed mold. At this time, the two cylinders 61 work and contract, driving the drive plate 62 to move in the direction of the guide rail plate 63 (the two cylinders 61 are connected in parallel and connected to an external air supply device through an air pipe, enabling the two cylinders 61 to act simultaneously. The method of enabling the two cylinders 61 to act simultaneously is not limited to the above parallel connection method, and other techniques in the prior art can also be used, which will not be elaborated here). The drive post 65 on one side of the drive plate 62 can be inserted into the material cavity 64 in the guide rail plate 63 and push the metal product in the material cavity 64 in the direction of the second mold core 4, causing the product in the material cavity 64 to enter the channel in the moving mold 1 through the discharge port 67, and then enter the guiding discharge part 5 from the channel in the moving mold 1. Since there are multiple metal products arranged in sequence in the channel, the metal product that just enters the channel can push the multiple metal products previously located in the channel to move. Since the metal product at the forefront in the guiding discharge part 5 combines with the material injected into the mold and is discharged together with the ejected product, when the ejector pin 33 ejects the formed product from the second mold core 4, the metal product at the forefront in the guiding discharge part 5 will be discharged together with the formed product. At this time, the drive post 65 pushes a new metal product in one material cavity 64 into the channel, causing the multiple arranged metal products previously existing in the channel and in the guiding discharge part 5 to move. The metal products in the guiding discharge part 5 move and fill the position of the previous metal product discharged along with the injection molded product, realizing the automatic transfer of the metal products. Then, the cylinder 61 works and extends, driving the drive plate 62 to move in the direction of the mounting plate 32 to reset the drive plate 62 and wait for the next material pushing action. After waiting for the above actions to be completed, materials are injected into the cavity of the mold to form an integral body with the metal products; the feed port of the material cavity 64 is connected to the discharge end of an external vibrating sorting feeder (vibrating disk). The vibrating sorting feeder numbers multiple metal products one by one and makes the metal products fall into the material cavity 64.

[0029] Please refer to Figure 1 and Figure 8, in this embodiment, one side of the second mold core 4 is connected to the first mold core 2. A limiting disk 21 for limiting the workpiece is fixedly connected to the inner wall of the first mold core 2, and a guiding column 22 for guiding the workpiece is fixedly connected to one side of the limiting disk 21. In order to prevent the position of the hardware product at the outlet of the guiding and discharging part 5 from changing after mold closing, the limiting disk 21 and the guiding column 22 are arranged inside the first mold core 2 to limit the hardware product. After mold closing, the guiding column 22 can be inserted into the hollow cavity of the hardware product, and at the same time, the limiting disk 21 can contact one side of the hardware product to prevent the hardware product from shifting during the injection molding process.
