[0002] Injection molding machines, also known as injection molding machines or injection machines, are the primary molding equipment used to convert heat-shrinkable plastics or thermosetting materials into various shapes using plastic molding molds. Injection molding machines are characterized by high production efficiency and high molding precision, making them widely used in mechanical processing. The material is melted by the melt barrel assembly, which requires the use of a nozzle.

[0003] When using existing nozzles, they are generally fixed in the injection molding machine. When plastic is injected, there will be a large number of impurity particles in the plastic, which can easily clog the nozzle after long-term use. However, since the nozzle is usually fixed to the injection molding machine by a large number of bolts, the nozzle is not easy to clean, thereby reducing the convenience of the nozzle.

[0010] A further improvement is that the shape of the connecting plate is L-shaped, the number of the connecting plates is two, and the connecting plates are symmetrically distributed on both sides of the nozzle. A limiting hole is opened on one side of the connecting plate, and one end of the threaded rod is threadedly connected to the inner wall of the limiting hole, so that the nozzle can be disassembled and assembled quickly and conveniently, and the filter cartridge can be better disassembled and assembled.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0026] Example 1:

[0027] A nozzle for an injection molding machine of thermoplastic plastics comprises a bolt 1 and a nozzle 2, wherein one end of the nozzle 2 is provided with an anti-blocking structure;

[0028] The anti-blocking structure includes a filtering mechanism 3 and a heating mechanism 4;

[0029] The filtering mechanism 3 includes a fixed rod 301, a limit block 302, a threaded rod 303, a connecting plate 304, and a nozzle 305. One end of the fixed rod 301 is connected to one side of the limit block 302. The inner wall of the limit block 302 is threadedly connected to the outer wall of the threaded rod 303. One end of the threaded rod 303 is threadedly connected to the inner wall of the connecting plate 304. One end of the connecting plate 304 is connected to one side of the nozzle 305. A clamping plate 306 is fixedly installed at one end of the nozzle 2. A filter cartridge 307 is clamped inside the clamping plate 306.

[0030] In this embodiment, there are two fixing rods 301, which are symmetrically distributed on both sides of the nozzle 2, and two limit blocks 302, which are symmetrically distributed on one end of the two fixing rods 301, so that the nozzle 305 can be better disassembled and assembled, and the injection molding work can be better performed;

[0031] Furthermore, the connecting plate 304 is L-shaped, and there are two connecting plates 304 symmetrically distributed on both sides of the nozzle 305. A limiting hole is provided on one side of the connecting plate 304, and one end of the threaded rod 303 is threadedly connected to the inner wall of the limiting hole, so that the nozzle 305 can be quickly and conveniently disassembled and assembled, and the filter cartridge 307 can be better disassembled and assembled.

[0032] Furthermore, the shape of the clip plate 306 is L-shaped, and there are two clip plates 306. The clip plates 306 are symmetrically distributed at one end of the nozzle 2, and the filter cartridge 307 is located between the two clip plates 306, so that the filter cartridge 307 can be quickly and conveniently disassembled and assembled, thereby enabling better filtering work.

[0033] When in use, when it is needed, the operator connects the nozzle 2 to the injection molding machine through the bolt 1, connects the filter cartridge 307 to one end of the nozzle 2, and inserts the nozzle head 305 into one end of the nozzle 2, so that it can be used, and the impurities in the raw material can be filtered through the filter cartridge 307, thereby effectively preventing the nozzle head 305 from being blocked. When it is necessary to disassemble the filter cartridge 307, the threaded rod 303 is rotated to move on the inner wall of the limit block 302, so that the threaded rod 303 can be pulled out from the connecting plate 304, and the limit fixation of the connecting plate 304 is cancelled. At this time, the connecting plate 304 is pulled out from the limit block 302, so that the nozzle head 305 can be removed from one end of the nozzle 2. At this time, the filter cartridge 307 can be pulled to be taken out from the clamping plate 306, and then the filter cartridge 307 can be disassembled. When it is necessary to install, the above steps can be repeated in reverse, so that it can be used better and the filter cartridge 307 can be disassembled and assembled quickly and conveniently.

[0034] Example 2:

[0035] On the basis of Example 1, the heating mechanism 4 includes a heating sleeve 401, a wire 402, an adjustment box 403, an adjustment plate 404, and a pull rod 405. The wire 402 is provided at one end of the heating sleeve 401, one side of the heating sleeve 401 is connected to one end of the adjustment box 403, the inner wall of the adjustment box 403 is slidably connected to both ends of the adjustment plate 404, one side of the adjustment plate 404 is connected to one end of the pull rod 405, and a wedge rod 406 is fixedly installed on the other side of the adjustment plate 404;

[0036] In this embodiment, there are two regulating boxes 403, which are symmetrically distributed on both sides of the heating jacket 401. A spring is fixedly installed between one side of the regulating plate 404 and the inner wall of the regulating box 403. A limiting groove is provided on one side of the nozzle 305, and one end of the wedge rod 406 is plugged into the inner wall of the limiting groove, so that the nozzle 305 can be better heated, thereby effectively preventing the melt from cooling and solidifying and clogging the nozzle 305. In addition, the heating jacket 401 can be quickly and conveniently disassembled and assembled.

[0037] Furthermore, one end of the bolt 1 is connected to one end of the nozzle 2, one side of the nozzle 2 is connected to one end of the fixing rod 301, and one end of the nozzle 305 is sleeved with one end of the heating sleeve 401.

[0038] When in use, after the injection molding work is stopped, the heating sleeve 401 is put on the nozzle head 305, and during the putting-in process, the nozzle head 305 can squeeze the wedge rod 406 to move, and the movement of the wedge rod 406 drives the adjustment plate 404 to slide inside the adjustment box 403, and the adjustment plate 404 slides and squeezes the spring. As the heating sleeve 401 continues to move, the wedge rod 406 can be inserted into the limiting groove provided on one side of the nozzle head 305, thereby fixing the heating sleeve 401 on the nozzle head 305, and the nozzle head 305 can be heated by the operation of the heating sleeve 401, thereby effectively preventing the melt from cooling and solidifying and clogging the nozzle head 305. When the heating sleeve 401 needs to be disassembled, the adjustment plate 404 can be moved by pulling the pull rod 405, and the adjustment plate 404 can be moved by the movement of the wedge rod 406, thereby the wedge rod 406 can be pulled out of the limiting groove, thereby the heating sleeve 401 can be removed, thereby enabling better use and improving the working efficiency of the nozzle.
