[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] like Figures 5 to 14As shown, the structure and function of a syringe processing system are described in detail below. Due to the special shape of the limit block 15, a syringe processing system for processing the limit block 15 is designed;

A compression spring is fixedly connected between the forming mold 31 fixed on the device bracket 21 and the forming mold 31 sliding on the device bracket 21. A compression spring is fixedly connected between the multiple forming molds 31 sliding on the device bracket 21, and a compression spring is fixedly connected between the forming mold 31 and the pulling frame 23.

[0042] The forming mold 31 is provided with a forming groove 32, and the upper end of the forming mold 31 is provided with an exhaust groove 33, which is connected to the forming groove 32. A stripper plate 34 is slidably connected in the forming groove 32, and a connecting column 35 is fixedly connected to the stripper plate 34. The connecting column 35 is slidably connected to the forming mold 31. The connecting column 35 sliding in the forming mold 31 on the lower side is fixedly connected to the forming mold 31 on the upper side, and the connecting column 35 sliding in the forming mold 31 on the uppermost side is fixedly connected to the pulling frame 23;

[0043] The device bracket 21 is fixedly connected to a telescopic mechanism I 41, and the telescopic end of the telescopic mechanism I 41 is fixedly connected to a lifting bracket I 42. The lifting bracket I 42 is rotatably connected to an injection cylinder 43. The injection cylinder 43 is provided with a plurality of injection holes, and the plurality of injection holes are respectively located in a plurality of molding grooves 32. The lifting bracket I 42 is fixedly connected to a power mechanism II for driving the injection cylinder 43 to rotate. The power mechanism II is preferably a servo motor. The injection cylinder 43 is rotatably connected to a connecting cavity 44. The connecting cavity 44 is connected to the injection cylinder 43, and a connecting pipe 45 is fixedly connected to the connecting cavity 44.

[0044] The injection cylinder 43 can be inserted into the multiple molding dies 31;

[0045] A telescopic mechanism II 51 is fixedly connected to the lifting bracket I 42, and a lifting bracket II 52 is fixedly connected to the telescopic end of the telescopic mechanism II 51. A closing column 53 is rotatably connected to the lifting bracket II 52. The closing column 53 is slidably connected to the injection cylinder 43. A plurality of closing disks 54 are fixedly connected to the closing column 53. The closing disks 54 can close the injection hole, and a plurality of connecting holes 55 are provided on the closing disks 54.

[0046] When in use, the power mechanism I is started, the output shaft of the power mechanism I starts to rotate, the output shaft of the power mechanism I drives the screw rod 22 to rotate, the screw rod 22 rotates and drives the pulling frame 23 to move through the thread, and the pulling frame 23 drives the forming mold 31 to move through the compression spring, such as Figure 6 As shown, multiple forming molds 31 are stacked relatively, that is, one forming mold 31 falls on the upper side of another forming mold 31, and the pulling frame 23 is located on the upper side of the uppermost forming mold 31;

[0047] Start the telescopic mechanism I 41, which can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 41 drives the lifting bracket I 42 to move, and the lifting bracket I 42 drives the injection cylinder 43 to move, so that the injection cylinder 43 is inserted between the multiple molding molds 31, as shown in FIG. Figure 6 As shown, the injection cylinder 43 passes through the plurality of stripper plates 34 so that the plurality of injection holes are respectively located in the molding grooves 32;

[0048] The injection molding pipe is pre-connected to the connecting pipe 45. The injection molding is made of rubber material. The injection molding passes through the connecting pipe 45 into the connecting cavity 44 and then into the injection cylinder 43. The injection molding is performed into the multiple molding grooves 32 through the multiple injection holes, and the limit blocks 15 are formed by injection molding in the multiple molding grooves 32.

[0049] Furthermore, the power mechanism II can be started, and the output shaft of the power mechanism II starts to rotate, which drives the injection cylinder 43 to rotate, so that the injection cylinder 43 rotates between the multiple molding dies 31, thereby uniformly passing the injection molded product into the molding groove 32, thereby ensuring uniform molding of the limit block 15;

[0050] Furthermore, when the injection holes need to be closed, the telescopic mechanism II 51 is activated. The telescopic mechanism II 51 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 51 drives the lifting bracket II 52 to move. The lifting bracket II 52 drives the closing column 53 to move. The closing column 53 drives the multiple closing disks 54 to move. The closing disks 54 close the multiple injection holes, thereby controlling the injection state of the injection cylinder 43.

[0051] Further, when the injection molding is completed, the power mechanism I is started, the output shaft of the power mechanism I starts to rotate, the output shaft of the power mechanism I drives the screw rod 22 to rotate, the screw rod 22 drives the pulling frame 23 to move when rotating through the thread, the pulling frame 23 moves upwards, the pulling frame 23 drives the plurality of forming molds 31 to move, and then the plurality of forming molds 31 are separated from each other under the action of the compression spring, and then the forming mold 31 drives the material withdrawal plate 34 to move upwards, and then the material withdrawal plate 34 withdraws the limiting block 15 in the forming groove 32;

[0052] Further, the power mechanism II can be started, the output shaft of the power mechanism II starts to rotate, the output shaft of the power mechanism II drives the injection cylinder 43 to rotate, and then it is ensured that the limiting block 15 will not be adhered to the injection cylinder 43 after being cooled and formed in the forming groove 32, and then it is ensured that the injection cylinder 43 and the limiting block 15 can be separated;

[0053] Further, the forming mold 31 can be provided with a cooling component for cooling and forming the limiting block 15;

[0054] As shown in Figures 2 to 4 , the structure and function of an injector are described in detail below;

[0055] An injector includes a needle cylinder 11, a push head 12 is slidingly connected in the needle cylinder 11, a push rod 13 is rotatably connected on the push head 12, a mounting seat 14 is threadedly connected on the push rod 13, a limiting block 15 is fixedly connected on the mounting seat 14, a plurality of tapered protrusions are arranged on the outside of the limiting block 15, and the tapered protrusions are in contact with the needle cylinder 11;

[0056] The limiting block 15 is made of an elastic material;

[0057] In use, when normal use is needed, the push rod 13 is moved, the push rod 13 drives the push head 12 to move, the push head 12 slides in the needle cylinder 11, and then the needle cylinder 11 completes extraction and injection;

[0058] When accurate injection is needed, the push rod 13 is rotated, the push rod 13 moves on the mounting seat 14 through the thread, since the mounting seat 14 is fixedly connected with the limiting block 15, a plurality of tapered protrusions are arranged on the outside of the limiting block 15, the tapered protrusions are in contact with the needle cylinder 11, the tapered protrusions limit the limiting block 15, it is ensured that the limiting block 15 will not rotate, and then the push rod 13 can move through the thread, the push rod 13 drives the push head 12 to move, and then accurate injection is realized;

[0059] Further, as shown in Figure 4As shown, since the outer portion of the limit block 15 is provided with a plurality of conical protrusions, the outer portion of the conical protrusions is in line contact with the syringe 11, and thus when the push rod 13 is pushed to move, the conical protrusions and the push rod 13 move in the same direction, and thus no large assist force is generated, thereby facilitating the pushing of the push rod 13;

[0060] like Figure 1 As shown, the steps and functions of a syringe processing method are described in detail below;
