Description

Nozzle

Technical Field

The utility model relates to a nozzle technical field that the plastic raw materials production was used especially relates to a nozzle.

Background

In the injection molding process, the material needs to be sprayed and guided to the corresponding position through the nozzle. The conventional injection molding nozzle of the conventional nozzle comprises a connecting part for connecting an injection molding machine, an outer hexagon nut for screwing the connecting part to the injection molding machine, and a spray cavity and a spray nozzle which are integrally formed with the connecting part and the outer hexagon nut. The head of the traditional nozzle is straight (please refer to A in figure 1), when LCP materials are produced, cold material residues are caused due to easy damage in holes, high-temperature foaming of products is caused, injection pressure is unstable, and the like, so that the problems that the nozzle needs to be repaired frequently, and the time is wasted due to too long disassembly and assembly time, the production efficiency is influenced, and the production cost is increased.

To this end, it is necessary to provide a nozzle that overcomes the above-mentioned drawbacks.

Disclosure of Invention

The utility model provides a nozzle through will penetrate the unilateral inclination that increases 3 of mouth head, can effectively improve cold charge and remain the problem, and then improved the life of penetrating the mouth, reduced the maintenance number of times of penetrating the mouth, improved production efficiency, reduced manufacturing cost.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is:

a nozzle, comprising: the nozzle comprises a connecting part used for connecting an injection molding machine and a nozzle main body connected with the connecting part, wherein a spout is formed in one end, far away from the connecting part, of the nozzle main body, and the slope of 3 degrees is increased in the spout.

Preferably, the diameter of one end of the nozzle close to the connecting part is 1.5mm, and the diameter of one end of the nozzle far away from the connecting part is 2.5 mm.

Preferably, a through hole is formed in the nozzle body near one end of the connecting part.

Preferably, the wall of the through hole is a polished surface.

Preferably, the connecting portion is provided with a second connecting hole.

Preferably, one end, far away from the nozzle body, of the second connecting hole is cylindrical, and one end, close to the nozzle body, of the second connecting hole is arranged to be circular truncated cone-shaped.

Preferably, the diameter range of the cylinder of one end of the second connecting hole far away from the nozzle body is as follows: the diameter of the lower bottom surface of the circular truncated cone at one end, close to the nozzle main body, of the second connecting hole is 20mm-20+0.03mm, and the diameter of the top surface of the circular truncated cone is 12 mm.

Preferably, the height of the cylinder is 10mm, and the height of the circular truncated cone is 10 mm.

Preferably, the length of the nozzle is 146.5mm, and the length of the spout is 10 mm.

The utility model discloses a penetrate the mouth, through increase 3 inclinations in the spout for raw materials for production can flow smoothly, avoided the cold burden to remain in penetrate on the mouth, reduced penetrate the number of times of mouth maintenance, further improved production efficiency and reduced manufacturing cost.

Detailed Description

The following embodiments of the present invention will be specifically explained with reference to the accompanying drawings, which are only used for reference and illustration, and do not limit the scope of the present invention.

Referring to fig. 2, the present invention provides a nozzle, including: connecting portion 1 and nozzle main part 2, wherein, connecting portion 1 is used for being connected with the injection molding machine, nozzle main part 2 with connecting portion 1 is connected. The length of the nozzle is 146.5 mm.

Specifically, connecting portion 1 has seted up second connecting hole 11, second connecting hole 11 is kept away from the one end of nozzle body 2 is the cylinder type, second connecting hole 11 is close to the one end setting of nozzle body 2 is the round platform type, second connecting hole 11 is kept away from the diameter scope of the cylinder of the one end of nozzle body 1 is: 20mm-20+0.03mm, the diameter of the lower bottom surface of the circular truncated cone, close to one end of the nozzle main body 2, of the second connecting hole 11 is 20mm-20+0.03mm, the diameter of the top surface of the circular truncated cone is 12mm, the height of the cylinder is 10mm, and the height of the circular truncated cone is 10 mm. Further, the end of the second connection hole 11 away from the nozzle body 1 may not be chamfered. It should be noted that the size of the connecting portion 1 is not limited to the above description, and can be prepared according to a certain ratio according to actual needs.

And one end of the nozzle body 2, which is far away from the connecting part, is provided with a nozzle 21, and the inclination of 3 degrees is increased in the nozzle 21. Specifically, the inner wall of the nozzle 21 is provided with an inclined surface with an inclination angle of 3 °. More specifically, the diameter of the end of the nozzle 21 close to the connecting portion 1 is 1.5mm, the diameter of the end of the nozzle 21 far from the connecting portion 1 is 2.5mm, the inside of the nozzle body 2 close to the end of the connecting portion 1 is provided with a through hole 22, the wall of the through hole 22 is a polished surface, and the length of the nozzle 21 is 10 mm.
