Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The feeding mechanism 2 includes a vertically arranged feeding pipe 21 and a vibration plate (not shown in the figure), so that the toothed nails are fed in sequence in the feeding pipe 21; the dislocation mechanism 3 includes a dislocation cylinder 31, a dislocation push block 32, and a clamping block 33. The dislocation cylinder 31 is fixedly connected to the mounting base 1 through a cylinder mounting member 34. The output end of the dislocation cylinder 31 is provided with a dislocation The positioning push block 32 is provided with a contoured groove 321 adapted to the toothed nail, and a notch is provided at the end of the contoured groove 321 away from the dislocation cylinder 31. The clamping block 33 extends into the notch and elastically clamps the toothed nail in the contoured groove 321. The toothed nail in the contoured groove 321 is moved between the discharge port of the incoming pipe 21 and the discharge position of the discharging mechanism 4 through the clamping block 33 and the discharging block 32; the discharging mechanism 4 is used to push the toothed nail at the discharge position out and allow it to enter the injection mold.

[0026] The utility model has a simple structure and is easy to assemble and disassemble. It can automatically load toothed nails, solving the problems caused by manual loading, avoiding damage to the mold caused by mistaken placement or omission, realizing unmanned injection molding, and increasing the workshop temperature to reduce the time of single injection molding, thereby improving injection molding efficiency. The toothed nails enter the vertically arranged incoming material pipe 21 in sequence through the vibrating disk, which can avoid the jamming of each toothed nail due to tooth meshing. Moreover, because the clamping block 33 elastically clamps the toothed nails, it can prevent the toothed nails from automatically falling into the discharge pipe of the discharge mechanism 4 due to gravity and disrupting the production rhythm. When discharge is required, the discharge mechanism 4 is activated to push the toothed nails out of the profiling groove 321, accurately controlling the discharge time of the toothed nails and ensuring the production rhythm. It should be noted that the utility model is also applicable to embedded parts without teeth, with wide applicability and high cost performance.

[0027] In the above structure, if Figure 1-3As shown, the mounting seat 1 is a split structure, including a mounting plate 11 and a mounting block 12. The mounting block 11 is vertically arranged to the mounting plate 12, and the discharge end of the feed pipe 21 is inserted into the mounting block 12. In order to reduce the movement resistance of the dislocated push block 32 and reduce friction, a groove 121 is provided in the middle of the bottom of the mounting block 12. The groove 121 is arranged across the outside of the profiling groove 321 and along the moving path of the toothed nail in the profiling groove 321, that is, the width of the groove 121 is greater than the outer diameter of the profiling groove 321. In addition, a gap is set between the bottom surface of the feed pipe 21 and the top surface of the dislocated push block 32 to further ensure that the dislocated push block 32 moves smoothly.

[0028] Among them, Figure 3-4 As shown, a slide 35 is disposed below the mounting block 12. A slot 351 is defined on the top surface of the slide 35. The offset pusher 32 is inserted into and slidably connected to the slot 351. Furthermore, the slide 35 and offset pusher 32 are constructed from heat-treated high-carbon, high-chromium alloy tool steel, offering excellent properties such as high hardness and wear resistance. This extends the service life of the slide and offset pusher and reduces maintenance frequency. Specifically, the offset pusher 32 is manufactured from SKD61, heat-treated to 50-58 HRC, while the slide 35 is manufactured from SKD11, heat-treated to 50-55 HRC.

[0029] like Figure 4 As shown, in order to ensure that the clamping block 33 accurately extends into the notch of the profiling groove 321, an opening groove 322 is provided at one end of the offset push block 32, and the opening direction of the opening groove 322 is the same as the notch direction of the profiling groove 321. One end of the clamping block 33 is inserted into the opening groove 322 and is slidably connected to the opening groove 322.

[0030] In addition, if Figure 3-4 As shown, the dislocation mechanism 3 also includes an elastic member, and the clamping block 33 elastically clamps the toothed nail through the elastic member. The elastic member includes a guide seat 36, a guide pin 37, and a spring 38. The guide seat 36 is fixed to the side of the mounting block 12 away from the dislocation push block 32, and is provided with a guide hole 361 in the form of a stepped hole. The guide pin 37 is inserted into the guide hole 361 and is limited in position by the outer boss cooperating with the stepped surface of the guide hole 361. The spring 38 is sleeved on the outer side of the guide pin 37, with one end connected to the clamping block 33 and the other end inserted into the large hole of the guide hole 361 and connected to the guide pin 37. The provision of the guide pin 37 ensures that the elastic force of the spring 38 is arranged along the axial direction of the guide pin, thereby ensuring that the clamping block 33 stably clamps the toothed nail.

[0031] Example 2

[0032] Based on the structure of Example 1, Figure 1 、 2As shown, the discharging mechanism 4 includes a discharging pipe 41 and a pushing assembly.

The pushing assembly is provided on the mounting plate 11 and is used to push the toothed nail moved to the discharging position into the discharging pipe 21.

[0033] In the above structure, if Figure 1 、 2 As shown, the pushing assembly includes a pushing cylinder 43, a push rod 44, and a guide tube 45. The pushing cylinder 43 is fixed on the top of the mounting plate 11, and a joint 46 is provided at its output end. The lower end of the joint 46 is provided with a T-slot, and the upper end of the push rod 44 is provided with a T-head connected to the T-slot, and the lower end is inserted in the guide tube 45 and slidably connected to the guide tube 45. The guide tube 45 is inserted in the mounting block 12 and is coaxially arranged with the discharge pipe 41.

[0034] In addition, if Figure 1 、 2 As shown, the incoming material mechanism 2 also includes a detection sensor 22, which is fixedly connected to the mounting base 1 and is located above the incoming material pipe 21. Specifically, the detection sensor 22 is installed on the cylinder body of the pushing cylinder 43, and is used to detect the amount of toothed nail material in the incoming material pipe 21 and control the incoming material rhythm.

[0035] The working principle of the utility model is as follows: the equipment is started, the vibrating disk arranges the toothed nails in sequence and discharges them to the incoming pipe 21, and the toothed nails follow the incoming pipe 21 into the docking interface (profiling groove) above the dislocation pushing block 32; then the dislocation mechanism 3 is started, the dislocation cylinder 31 is pushed forward, and after pushing forward a distance, the clamping block 33 extends into the notch of the profiling groove 321, the spring 38 is compressed, the clamping block 33 clamps the toothed nail, and the toothed nail is tightly fixed in the profiling groove 321, and then is pushed to the top of the discharge pipe 41 (discharge position) by the dislocation pushing block 32; when the feeding device moves to the place where discharging is required, the discharging mechanism 4 is started, and the push rod 44 pushes the toothed nail out of the profiling groove 321 under the action of the pushing cylinder 43, and falls into the discharge pipe 41, and finally reaches the discharge setting position.
