[0017] The specific implementation methods of the utility model are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model.

[0018] like Figure 1-5As shown in the figure, the utility model provides an injection molding device for plastic pipe clamps, which includes a fixed mold 2, a main injection molding device 4 and a movable mold 6. The fixed mold 2 is arranged on a fixed mold base 3 on an injection molding machine 1. The main injection molding device 4 is arranged on the injection molding machine 1 and its injection head extends into the fixed mold 2. The fixed mold base 3 is connected to a mounting seat 5 on the main injection molding device 4 through a pull rod 7. The movable mold 6 is slidably connected to the pull rod 7. A moving plate 8 is also slidably connected to the pull rod 7. A sliding sleeve 81 sleeved on the pull rod 7 is arranged between the moving plate 8 and the movable mold 6. A material discharging assembly 9 corresponding to the pipe clamp mold cavities on the movable mold 6 is arranged on the side of the moving plate 8. An oil cylinder 51 is arranged outside the mounting seat 5, and the end of the piston rod of the oil cylinder 51 is connected to the side of the moving plate 8.

[0019] In addition, the material discharging assembly 9 includes a guide rod 91 and a spring 93. The guide rod 91 is slidably connected to the movable mold 6 and a mounting frame 92 on the side of the movable mold 6. The mounting frame 92 is of a "U" - shaped structure and its opening faces the direction of the moving plate 8. One end of the guide rod 91 is inserted into the pipe clamp mold cavity on the movable mold 6. A rubber pad 95 is arranged at the other end of the guide rod 91. The spring 93 is sleeved on the guide rod 91 and is located between the moving plate 8 and a push plate 94 on the guide rod 91. By arranging the rubber pad 95 and the spring 93 on the guide rod 91, the guide rod 91 is buffered during the moving process, avoiding hard collision between the guide rod 91 and the device and causing damage.

[0020] In addition, four pull rods 7 are arranged in a rectangular array between the fixed mold base 3 and the mounting seat 5. By arranging multiple pull rods 7, the movable mold 6 and the moving plate 8 are guided, enabling the movable mold 6 and the moving plate 8 to move smoothly.

[0021] Specific implementation method and principle:

[0022] When the utility model is actually applied, the piston rod of the oil cylinder 51 on the mounting seat 5 is controlled to extend. The piston rod of the oil cylinder 51 drives the moving plate 8 and the movable mold 6 to move towards the fixed mold 2 along the pull rod 7. When the movable mold 6 and the fixed mold 2 are closed, raw materials are injected into the pipe clamp mold cavity of the movable mold 6 through the injection head of the main injection molding device 4. After injection molding, the piston rod of the oil cylinder 51 is controlled to retract. The piston rod of the oil cylinder 51 drives the moving plate 8 and the movable mold 6 to move away from the fixed mold 2 along the pull rod 7. When the guide rod 91 on the material discharging assembly 9 contacts the inner side of the mounting seat 5, it drives the guide rod 91 to move and unload the formed parts in the pipe clamp mold cavity. The spring 93 on the guide rod 91 is compressed. When the moving plate 8 and the movable mold 6 move towards the fixed mold 2 again, under the action of the elastic force of the spring 93 on the guide rod 91, the end of the guide rod 91 in the pipe clamp mold cavity retracts into the movable mold 6 again, avoiding damaging the forming of the parts during injection molding.

[0023] To sum up, when the tube clamp mold cavity of the driven mold 6 needs to be unloaded, the molded parts are unloaded through the guide rod 91 of the material return assembly 9. During the unloading process, the spring 93 and the rubber pad 95 on the guide rod 91 provide a buffering effect, which effectively avoids the direct collision between the guide rod 91 and other hard objects, thereby preventing damage to the guide rod 91 and the mounting seat 5. This design increases the service life and stability of the equipment, reduces maintenance costs, and makes the production process smoother.

[0024] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
