Referring to fig. 5, 6, 7, 8, 9 and 10, in detail, in the present embodiment, the locking assembly 400 includes a cylinder 410, a sleeve 420 and a core 430.

The cylinder 410 is fixedly installed at one side of the positioning base 200 close to the extruder body 100, the sleeve 420 penetrates from one side of the positioning base 200 close to the extruder body 100 to one end wall of the second fitting hole 220 close to the first fitting hole 210, and the sleeve 420 extends into the second fitting hole 220. The sleeve 420 is fixedly connected with the positioning seat 200.

The core 430 is slidably received in the sleeve 420, and the core 430 is coupled to a piston rod of the cylinder 410 such that the core 430 is driven by the cylinder 410. The core 430 is slidably fitted into the sleeve 420 along the length of the sleeve 420.

The end of the core 430 remote from the extruder body 100 is formed with a groove 431, and the groove 431 is formed by recessing the outer wall of the core 430. The groove wall 431a of the groove 431 has an arc shape, and a plane of a circumference corresponding to the groove wall 431a of the groove 431 passes through the central axis of the core 430.

A stopper 432 is received in the groove 431, and the stopper 432 is hinged to an edge of the groove 431 on a side away from the extruder body 100. One side wall of the stop block 432, which is attached to the groove wall 431a of the groove 431, is in an arc shape corresponding to the groove wall 431a of the groove 431. The rotational axis of the stopper 432 is disposed perpendicular to the central axis of the core 430. When the stopper 432 is received in the groove 431, a side of the stopper 432 away from the groove wall 431a of the groove 431 is flush with the outer surface of the core 430, so that it can be ensured that the core 430 can slide along the sleeve 420 when the stopper 432 is received in the groove 431.

One end of the sleeve 420 far away from the extruder body 100 is provided with a notch 421 for the stop block 432 to be turned out, the notch 421 penetrates through the pipe wall of the sleeve 420, and the notch 421 extends along the length direction of the sleeve 420.

Gap 421 is spaced from the end wall of sleeve 420 remote from extruder body 100, and recess 431 is spaced from the end wall of core 430 remote from extruder body 100. The distance between indentation 421 and the end wall of sleeve 420 is greater than the distance between groove 431 and the end wall of core 430.

The inner wall of the sleeve 420 is provided with a projection 422, and the position of the projection 422 corresponds to the position of the notch 421. The core 430 is provided with a sliding groove 433 used for being matched with the bump 422, and the sliding groove 433 extends along the length direction of the core 430 and penetrates to a section of end surface of the core 430 far away from the extruding machine body 100. Runner 433 extends through groove 431. When the core 430 is received in the sleeve 420, the projection 422 fits in the slide groove 433, and the projection 422 is able to slide along the slide groove 433. When the stopper 432 is received in the groove 431, the projection 422 is located on the side of the groove 431 near the extruder body 100.

The die 300 is provided with a fitting through hole 310 for passing the sleeve 420 and the core 430, and in this embodiment, the fitting through hole 310 includes an expanding section 311 and a reducing section 312 which are communicated with each other, and the reducing section 312 is located on one side of the expanding section 311 close to the extruder body 100. The diameter of the reduced diameter section 312 is the same as the outer diameter of the sleeve 420, and the precise positioning of the die 300 during the installation of the die 300 can be realized by matching the matching through hole 310 with the sleeve 420.

When the die 300 is installed, the die 300 is fitted to the second fitting hole 220, and the sleeve 420 is inserted through the fitting through-hole 310 of the die 300, the sleeve 420 being able to penetrate into the expanded diameter section 311 of the fitting through-hole 310 through the reduced diameter section 312 of the fitting through-hole 310. When the die 300 is fitted to the end wall of the second fitting hole 220 adjacent to the first fitting hole 210, the die 300 is mounted in position with the notch 421 of the sleeve 420 positioned in the enlarged diameter section 311 of the fitting through hole 310. As shown in fig. 11.

The core 430 is driven by the cylinder 410 to move in the sleeve 420, so that the core 430 slides in the sleeve 420 to a side close to the extruder body 100, and since the projection 422 is fixedly connected to the inner side of the sleeve 420, relative movement occurs between the projection 422 and the core 430, and the projection 422 slides along the slide groove 433 of the core 430 relative to the core 430.

Since the projection 422 is initially located on the side of the groove 431 close to the extruder body 100, during the movement of the core 430, the projection 422 approaches the groove 431, and the projection 422 moves toward the groove 431 under the guidance of the slide groove 433, and when the projection 422 slides into the groove 431, it comes into contact with the stopper 432 received in the groove 431, as shown in fig. 12.

Since the protrusion 422 is in contact with the end of the stop block 432 close to the extruder body 100 and the end of the stop block 432 far from the extruder body 100 is hinged to the end of the groove 431 far from the extruder body 100, as the core 430 continues to slide, the protrusion 422 pushes the stop block 432 to start rotating, so that the stop block 432 turns up from the groove 431, as shown in fig. 13.

Since the protrusion 422 is disposed at a position corresponding to the position of the notch 421, after the protrusion 422 pushes the stopper 432 up, the stopper 432 turns up from the groove 431, and at the same time, the protrusion 422 can protrude out of the sleeve 420 through the notch 421, so as to be regarded as protruding out of the notch 421 of the sleeve 420.

As the core 430 continues to move to the side close to the extruder body 100, the turned-out stop block 432 can abut against the end wall of the diameter expanding section 311 at the end close to the diameter reducing section 312, and after the stop block 432 abuts against the end wall of the diameter expanding section 311, as the core 430 continues to slide to the side of the extruder body 100, the end wall of the diameter expanding section 311 can push the stop block 432 to be turned out completely from the groove 431, and the stop block 432 can be made to abut against the end wall of the diameter expanding section 311 fully, as shown in fig. 14.

In this way, the locking of the mouthpiece 300 is achieved, and the mouthpiece 300 is securely mounted into the second coupling hole 220.

It should be noted that when the stop block 432 is fully ejected from the groove 431, the stop block 432 will not block the movement of the protrusion 422, and because the sliding groove 433 extends all the way to the end wall of the body 100 of the extruder of the core 430, when the stop block 432 is fully ejected, the movement of the protrusion 422 is not obstructed, and the normal sliding of the core 430 will not be affected.

When the die 300 needs to be replaced, the core 430 is pushed by the cylinder 410 to the side away from the extruder body 100, so that the above-mentioned reverse rotation can be realized, and the stop block 432 can be smoothly turned back to the groove 431 under the pushing of the edge of the notch 421.

The whole process of replacing the neck ring mold 300 and fixing the neck ring mold 300 can be completed by the order control cylinder 410, and the process is simple, convenient, efficient and convenient.

In this embodiment, when the cylinder 410 assembly drives the core 430 to slide away from the extruder body 100, the core 430 slides to the limit where the end surface of the core 430 is flush with the end surface of the sleeve 420.

In conclusion, the novel improved plastic extruding machine 1000 can realize quick replacement and quick locking of the neck ring mold 300, is simple, convenient, stable and quick, greatly improves the efficiency of replacing the neck ring mold 300, shortens the idle time generated by replacing the neck ring mold 300, improves the linking efficiency between different production batches, and has positive significance for further improving the comprehensive yield.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
