Detailed Description
In order that those skilled in the art will better understand the utility model and thus more clearly define the scope of the utility model as claimed, it is described in detail below with respect to certain specific embodiments thereof. It should be noted that the following is only a few embodiments of the present invention, and the specific direct description of the related structures is only for the convenience of understanding the present invention, and the specific features do not of course directly limit the scope of the present invention.
Referring to fig. 1 and 2, the utility model adopts the following technical scheme that the extrusion nozzle of the injection molding machine comprises a connecting body 1 connected with an extrusion port of the injection molding machine and a nozzle head 2 in threaded connection with the connecting body 1, wherein a vertical first communicating channel 3 is formed on the connecting body 1, a second communicating channel 4 communicated with the first communicating channel 3 is formed on the nozzle head 2, the inner diameter of the first communicating channel 3 is consistent up and down, a first thread 5 is formed on the inner wall of the nozzle head 2, a matching thread matched with the first thread 5 is formed on the outer wall of the connecting body 1, a groove is formed between the nozzle head 2 and the connecting body 1, and a sealing ring 6 is fixed in the groove.
One is as follows: the inner diameter of the second communicating channel 4 decreases in order from one side to the other side of the connecting body 1.
The second step is as follows: the second communicating channel 4 is communicated with the first communicating channel 3 to form a third channel 7, a first groove body 10 is formed in the nozzle head 2, and the third channel 7 is formed by the first groove body 10. The diameter of the third passage 7 is larger than the inner diameter of the first communicating passage 3 and is larger than or equal to the maximum diameter of the second communicating passage 4.
Either or both of these may be used alternatively.
One side of the nozzle head 2 close to the connector 1 is provided with a limiting ring 8, the limiting ring 8 and the nozzle head 2 are integrally formed, and the height of the limiting ring 8 is greater than that of the first thread 5. The outer equipartition of spacing ring 8 has strip recess 9, and spacing ring 8 not only can increase rotatory frictional force, can also increase the thickness of first screw thread 5 department, increases life, prevents the rupture damage.
Compared with the prior art, the utility model has the advantages that: the nozzle head 2 is simple in structure, the nozzle head can be detached from the connector 1, if the extrusion material in the connector 1 is blocked when meeting cold, and the first communication channel 3 is vertical, the extrusion material agglomerated inside can be pulled out, so that the nozzle head is convenient to use for multiple times, and the service life is prolonged.
