[0022] like Figures 1-5 As shown, this utility model provides a technical solution: an adjustable injection molding equipment for cap production, including an injection molding machine 1, a lower mold groove 3, and a connecting plate 4. The top surface of the injection molding machine 1 is provided with an adjusting part 2 capable of adjusting and fixing the injection molding connecting pipe. The adjusting part 2 includes:

[0023] The bottom surface of the fixed disc 21 is fixedly connected with the top surface of the injection molding machine 1, the top surface of the fixed disc 21 is rotationally connected with a knob 22, the inner side of the knob 22 is provided with a pushing groove 23, the shape of the pushing groove 23 is arc-shaped, the side surface of the knob 22 penetrates a pull rod 24, the pull rod 24 is slidingly connected with the knob 22, one end of the pull rod 24 located at the inner side of the knob 22 is fixedly connected with a ratchet pawl 25, the surface of the ratchet pawl 25 is fixedly connected with a spring 26, and the end of the spring 26 away from the ratchet pawl 25 is fixedly connected with the inner side of the knob 22. The fixed disc 21 penetrates and is fixedly connected with a ratchet wheel 27, because the bottom surface of the fixed disc 21 is fixedly connected with the top surface of the injection molding machine 1, and the ratchet wheel 27 is penetrated and fixedly connected with the fixed disc 21, the ratchet wheel 27 can always keep in a fixed state, and the top surface of the fixed disc 21 is provided with a sliding groove 28. The inner side of the sliding groove 28 penetrates a push rod 29, the bottom of the push rod 29 is rotationally connected with a sliding block 210, and the sliding block 210 is located at the inner side of the sliding groove 28 and is slidingly connected, so that the sliding groove 28 limits the sliding block 210, and the sliding block 210 can only slide in the sliding groove 28, so that when the push rod 29 is pushed by the pushing groove 23, the sliding block 210 slides in the sliding groove 28 and pushes the push rod 29, and the push rod 29 is slidingly connected with the fixed disc 21. One end of the push rod 29 close to the axis of the fixed disc 21 is fixedly connected with a locking block 213, when the push rod 29 is pushed, the locking block 213 is in contact with the injection connecting pipe and locks the injection connecting pipe, and when the knob 22 rotates, the ratchet pawl 25 is limited by the pull rod 24, the ratchet wheel 27 can limit the ratchet pawl 25 in one direction, so that the knob 22 cannot reverse after being twisted, thereby stably fixing the injection pipe, and the end of the push rod 29 away from the locking block 213 is fixedly connected with the sliding block 210. The sliding block 210 penetrates the sliding groove 28, and the sliding block 210 is slidingly connected with the inner side of the sliding groove 28, and the sliding block 210 and the inner side of the sliding groove 28 are fixedly connected with a spring 212. The top end of the sliding block 210 penetrates a push rod 211, the knob 22 is rotated, the arc-shaped pushing groove 23 in the inner side of the knob 22 pushes the push rod 211 in the pushing groove 23, the push rod 211 slides along the arc-shaped pushing groove 23, the push rod 211 is rotationally connected with the sliding block 210, and the top end of the push rod 211 is inserted into the pushing groove 23. The number of the locking blocks 213 is three, when the three groups of circumferentially arranged locking blocks 213 move to the center of the fixed disc 21 at the same time, the injection pipes of different sizes can be fixed, and the pipes cannot be inclined and always keep vertical downward, and the spring 215 is fixedly connected between every two groups of locking blocks 213, and the inner side of the three groups of locking blocks 213 penetrates the elastic ring 214.

[0024] Based on the above embodiment, when the injection molding device is in use, the upper mold base is first fixed with the connecting plate 4, then the lower mold base is placed in the lower mold groove 3 and fixed, and the injection molding conveying pipe is inserted into the inner side of the fixed disc 21. Since the bottom surface of the fixed disc 21 is fixedly connected with the top surface of the injection molding machine 1, and the ratchet wheel 27 is penetrated by the fixed disc 21 and fixedly connected, the ratchet wheel 27 can always remain in a fixed state. At this time, the rotating knob 22 is rotated, so that the arc-shaped push groove 23 in the inner side of the rotating knob 22 pushes the push rod 211 located in the push groove 23, so that the push rod 211 slides along the arc shape of the push groove 23. However, the bottom of the push rod 211 is rotationally connected with the sliding block 210, and the sliding block 210 is located in the inner side of the sliding groove 28 and is slidingly connected. Therefore, the sliding groove 28 limits the sliding block 210, so that the sliding block 210 can only slide in the sliding groove 28. Therefore, when the push rod 211 is pushed by the push groove 23, the sliding block 210 slides in the sliding groove 28 and pushes the push rod 29. When the push rod 29 is pushed, it will abut against the locking block 213 to lock the injection molding connecting pipe. When the rotating knob 22 is rotated, the pawl 25 is driven by the pull rod 24 to be limited, and the pawl 25 is unidirectionally limited by the ratchet wheel 27. Therefore, after the rotating knob 22 is twisted, it will not be reversed, so that the injection molding pipe can be stably fixed. Pulling the pull rod 24 makes the pawl 25 no longer engage with the ratchet wheel 27, so that the rotating knob 22 can be reversed. The forward and reverse rotation of the rotating knob 22 can adjust the locking degree of the locking block 213, and further fix the injection molding pipe of different sizes, so that the application range is wider, and the replacement and cleaning of the injection molding pipe are more convenient.

[0025] When the three groups of circumferential array locking blocks 213 move to the center of the fixed disc 21 at the same time, the injection molding pipe of different sizes can be fixed, and the pipe can be prevented from tilting and always remain vertically downward, so that the leakage of raw materials caused by the tilting of the injection molding pipe is avoided.

[0026] The above has made a detailed description of the general description of the present application, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, without departing from the modification or improvement of the spirit of the present application, it is within the protection scope of the present application.
