[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-6 The present invention provides the following technical solution.

[0033] Example 1: To address the inconvenience of disassembling and replacing molds in existing technologies, this example provides a plastic clamp injection mold that facilitates demolding. The mold includes a lower mold 1, a base plate 2, positioning plates 3, mounting plates 4, protrusions 5, fixing rods 6, and fixing caps 7. The lower mold 1 rests on the base plate 2, and multiple sets of positioning plates 3 are fixedly connected to the corner of the upper end of the base plate 2. The positioning plates 3 are fitted against the lower mold 1. The mounting plates 4 are symmetrically positioned... The lower mold 1 of the injection mold has protrusions 5 for positioning on both sides and through the middle of the mounting plate 4. The protrusions 5 are fixedly connected to the left and right sides of the lower mold 1 of the injection mold. The mounting plate 4, together with the protrusions 5 and the lower mold 1 of the injection mold, forms a disassembly structure on the upper end of the base plate 2. The outer side of the positioning plate 3 is fixedly connected to a fixing rod 6, and the fixing rod 6 is inserted into the front and rear sides of the mounting plate 4. The outer side of the fixing rod 6 is threaded with a fixing cap 7 for limiting the position. The fixing cap 7 is fitted to the outer side of the mounting plate 4. Figure 1 , Figure 2 and Figure 3As shown, firstly, the lower mold 1 of the injection mold is placed on the upper end of the base plate 2. The positioning plate 3 can be used to position the base plate 2 and the lower mold 1 of the injection mold. Then, the mounting plate 4 is pulled towards the side closer to the lower mold 1 of the injection mold. The mounting plate 4 slides with the fixing rod 6, so that the protrusion 5 is inserted into the middle of the mounting plate 4, which facilitates the positioning of the lower mold 1 of the injection mold on the base plate 2. After the lower mold 1 of the injection mold is positioned, the fixing cap 7 connected to the outer surface of the fixing rod 6 is rotated so that the fixing cap 7 is respectively attached to the front and rear ends of the mounting plate 4, which limits the positioning between the mounting plate 4 and the fixing rod 6. In addition, the lower mold 1 of the injection mold can be disassembled and replaced by performing the above operations.

[0034] Example 2: To address the problem in existing technologies where molds reach high temperatures during long-term molding and processing, making cooling inconvenient and impacting plastic production, this example provides a plastic clamp injection mold with easy demolding. The mold includes a cooling mechanism consisting of an inlet 8, cooling channels 9, and an outlet 10. Cooling channels 9 are located at the left and right ends of the lower mold 1. Both the inlet 8 and outlet 10 are fixedly connected to the left and right sides of the lower mold 1. The inlet 8 is connected to the outlet 10 via the curved cooling channels 9. Both the inlet 8 and outlet 10 are bolted to external cooling pipes. Figure 1 and Figure 4 As shown, the inlet 8 and outlet 10 are connected to the external cooling pipes by bolts. The coolant is introduced into the cooling channel 9 through the inlet 8 through the external cooling pipes and then discharged through the outlet 10. This allows for continuous circulation cooling of the lower mold 1 during injection molding, preventing the lower mold 1 from overheating during long-term use and affecting the production of plastic clamps.

[0035] Example 3: To address the problem of complex demolding structures in existing technologies, this example provides a plastic clamp injection mold for easy demolding, comprising a demolding mechanism 11. The demolding mechanism 11 is located within the lower mold 1 of the injection mold and consists of a demolding module 12, a vertical rod 13, a movable block 14, a movable rod 15, a spring 16, and a movable push plate 17. The demolding module 12 is located inside the lower mold 1, and its upper end is fixedly connected to the vertical rod 13, which extends and retracts within the lower mold 1. The lower end of the demolding module 12 is fitted with the movable block 14, and the lower end of the module 12 engages with the upper end of the movable block 14. The front end of the movable block 14 is fixedly connected to the movable rod 15, which slides back and forth with the lower mold 1. A spring 16 is fitted onto the outer surface of the front side of the movable rod 15, and the front end of the movable rod 15 is fixedly connected to the movable push plate 17. Figure 1 , Figure 5 and Figure 6 As shown, after the plastic clip in the lower mold 1 of the injection mold is formed, by pressing the movable push plate 17 to the rear, the movable push plate 17 pushes the movable rod 15 to slide between the lower mold 1 of the injection mold. The movable push plate 17 squeezes the spring 16, causing the spring 16 to undergo elastic deformation. The movable rod 15 pushes the movable block 14 to move backward, causing the movable block 14 to push the ejector module 12 to move upward. At this time, the ejector module 12 drives the vertical rod 13 to slide upward, which can eject the formed plastic clip in the lower mold 1 of the injection mold, making it convenient for demolding and unloading.
