Technical Field
[0001] This utility model relates to the field of injection molding machine technology, specifically to an anti-clogging component for injection molds. Background Technology
[0002] An injection molding machine is a device that uses injection molds to make various shapes of plastic products from thermoplastic plastics. It utilizes the plasticizing flow of thermosetting plastics during the first heating, which quickly fills the cavity under pressure, and then produces a cross-linking reaction to solidify into products with a specific shape and size. The injection molding machine injects the raw material into the mold through the injection head.
[0003] The nozzle of the injection head of an injection molding machine is relatively small. During the injection process, impurities in the molten plastic material or incompletely melted plastic can easily clog the injection head when injected into the mold. Current technology usually adds a filter plate inside the injection head to prevent clogging.
[0004] However, it is inconvenient to quickly disassemble the filter plate, cannot guarantee the sealing of the connection, and is inconvenient to quickly disassemble and replace the injection head, making it impractical. To address these issues, an anti-clogging component for injection heads in injection molds is proposed. Utility Model Content

A sealing ring 15 is fixedly connected to the bottom of the connecting sleeve 1. An injection head 16 is provided at the bottom of the connecting sleeve 1. A telescopic groove 17 is opened at the top of the injection head 16. Multiple springs 18 are fixedly connected inside the telescopic groove 17. A sealing ring 19 is fixedly connected to the top of the spring 18. The sealing ring 19 can be moved and expanded within the telescopic groove 17 by the compression and contraction of the spring 18. Four limiting grooves 20 are opened on the inner wall of the connecting sleeve 1. The limiting grooves 20 play a limiting role. A filter plate 21 is provided at the bottom of the inner wall of the connecting sleeve 1. The filter plate 21 can filter impurities in the material and prevent clogging. Four limiting plates 24 are fixedly connected to the outer side of the filter plate 21. Connecting rings 22 are fixedly connected to the outer side of the bottom of the connecting sleeve 1 and the outer side of the top of the injection head 16.

[0033] Reference Figure 3 The disassembly assembly includes mounting bases 5, both of which are fixedly connected to the outside of the connecting sleeve 1. The top of the mounting base 5 is provided with a mounting groove 6, and a bidirectional threaded rod 7 is rotatably connected through the mounting groove 6. The outer ring of the bidirectional threaded rod 7 is threaded with movable clips 9 on both sides. The disassembly assembly can drive the two movable clips 9 to move relative to each other, so that the movable clips 9 can be inserted into the insertion holes 14 on both sides of the fixed block 13 to achieve a fixing effect, which facilitates the quick installation and disassembly of the injection head 16 below.
[0034] Reference Figure 2 and Figure 4Stabilizing blocks 12 are fixedly connected to both the front and rear sides of the mounting ring 11, and the lower end of the stabilizing block 12 is set in the stabilizing groove 4. After the stabilizing block 12 is inserted into the stabilizing groove 4, it can improve the stability of the connection between the connecting sleeve 1 and the mounting ring 11. The sealing ring 15 is set in the sealing groove 2, and the outer side of the sealing ring 15 is slidably connected to the inner wall of the sealing groove 2, so that the sealing ring 15 can be inserted into the sealing groove 2 to achieve the sealing effect.

The bidirectional threaded rod 7 can be rotated by the knob 8. The moving clamp 9 is set on both sides of the fixed block 13.
[0035] Working Principle: During installation, the filter plate 21 is first inserted along the limiting groove 20 on the inner wall of the connecting sleeve 1 via the limiting plate 24 on its outer side. Then, the top of the injection head 16 is inserted into the bottom of the connecting sleeve 1, aligning the connecting rings 22 at the bottom of the connecting sleeve 1 and the top of the injection head 16. Next, screws 23 are threaded through and connected to the two connecting rings 22, thus tightly connecting the injection head 16 and the connecting sleeve 1 together. At this time, the sealing ring 19 in the telescopic groove 17 at the top of the injection head 16 is in close contact with the bottom of the connecting sleeve 1 under the action of the spring 18, providing a seal and preventing material leakage. When connecting the connecting pipe 10 to the connecting sleeve 1, the mounting ring 11 at the bottom of the connecting pipe 10 is aligned with the top of the connecting sleeve 1, so that the sealing ring 15 at the bottom of the mounting ring 11 is inserted into the sealing groove 2 at the top of the connecting sleeve 1, achieving a sealed connection. Simultaneously, the stabilizing blocks 12 on both sides of the mounting ring 11 are inserted into the stabilizing grooves 4 in the connecting block 3, stabilizing the connecting pipe 10. Then, by rotating the knob 8 in the disassembly assembly, the bidirectional threaded rod 7 is rotated. The bidirectional threaded rod 7 drives the two movable clamps 9 on both sides to move towards each other along the mounting groove 6 and insert into the insertion holes 14 on both sides of the fixing block 13, thereby tightly clamping the fixing block 13 and further stabilizing the connection between the connecting pipe 10 and the connecting sleeve 1. During the injection molding process, the injection material enters the connecting sleeve 1 from the connecting pipe 10, is filtered by the filter plate 21, and then enters the injection head 16 for injection. The filter plate 21 can intercept impurity particles in the material to prevent them from clogging the injection head 16. When it is necessary to disassemble the connecting pipe 10 or the injection head 16 for cleaning or maintenance, rotate the knob 8 in the opposite direction to loosen the movable clamps 9 from the fixing block 13, and the connecting pipe 10 can be disassembled; unscrew the screws 23 on the connecting ring 22 to remove the injection head 16 from the connecting sleeve 1, which facilitates cleaning of various components, replacement of the filter plate 21, and other operations, ensuring the smooth progress of the injection molding process and effectively preventing the injection head 16 from clogging.
