[0021] This utility model embodiment provides an energy-saving nozzle for an injection molding machine, such as... Figure 1-4 As shown, the nozzle body includes a nozzle body 1. Two partitions 2 slide inside the nozzle body 1. The partitions 2 are arranged vertically. A slide rod 3 is fixedly installed on one side of the two partitions 2 away from each other. The end of the slide rod 3 away from the partitions 2 is considered the outer end. Rings 11 are symmetrically welded on the left and right sides of the nozzle body 1. The outer end of the slide rod 3 passes through the nozzle body 1 and the rings 11 laterally. A membrane 4 is fixedly installed at the bottom of the partitions 2. The side of the membrane 4 away from the partitions 2 is fixedly connected to the inner wall of the rings 11.

[0022] The nozzle body 1 has symmetrical drive units on its front and rear sides. The control partitions 2 of the drive units are far apart from each other. The slide rod 3 is fitted with a spring 31. One end of the spring 31 is welded to the outer end of the slide rod 3, and the other end of the spring 31 is in contact with the outer wall of the nozzle body 1.

[0023] The drive unit consists of a motor-driven roller 5, a steel wire 51, a connecting rod 21, and an extension rod 15. The roller 5 is pivotally connected to the outside of the nozzle body 1. The connecting rod 21 is symmetrically fixedly installed at the lower end of the partition 2. Horizontal through slots 14 are symmetrically opened on the front and rear sides of the nozzle body 1.

[0024] The connecting rod 21 extends to the outside of the nozzle body 1 through the through groove 14. The extension rod 15 is symmetrically welded to the front and rear sides of the nozzle body 1. The extension rod 15 is aligned with the connecting rod 21. One end of the steel wire 51 is welded to the connecting rod 21, and the other end of the steel wire 51 passes through the extension rod 15 and is welded to the roller 5.

[0025] The nozzle body 1 has grooves 13 on both the left and right sides of its inner wall. The grooves 13 are aligned with the through grooves 14. The film 4 is fixedly inserted into the groove 13 on the side away from the partition 2. The film 4 extends to the outside of the nozzle body 1 through the through grooves 14 on the front and back sides.

[0026] A protrusion 12 is welded to the outside of the nozzle body 1. A motor is fixedly installed on the protrusion 12, and the motor drive shaft is fixedly connected to the roller 5.

[0027] The outer end of the slide bar 3 has a flange, and the spring 31 is welded to the flange.

[0028] Working principle: The motor drives the roller 5 to rotate, and the roller 5 winds the steel wire 51. The steel wire 51 pulls the connecting rod 21 towards the extension rod 15. This causes the two partitions 2 to move away from each other, and the membrane 4 to be retracted. At this time, the spring 31 is stretched, and the entire nozzle opens. When the motor stops working, the spring 31 contracts, causing the slide rod 3 to move into the nozzle body 1. The two partitions 2 come into contact with each other, and the membrane 4 unfolds, sealing the nozzle opening through the partitions 2 and the membrane 4.

[0029] In summary, the energy-saving nozzle of this injection molding machine has two partitions 2 slidingly fitted inside the nozzle body 1. The partitions 2 are connected to a slide rod 3, which extends to the outside of the nozzle body 1. A thin film 4 is connected to the bottom of the partitions 2. Through the cooperation of roller 5, steel wire 51, and spring 31, the partitions 2 are moved away from or closer to each other, thereby controlling the nozzle to close and playing an adjustment role, so that the nozzle can close in time and avoid excessive waste of injection molding material.
