Detailed Implementation

[0024] 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.

[0025] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, this utility model provides a technical solution: an injection mold for an easily detachable handle, comprising: a base 1; a water-cooled plate 2 fixedly connected to the top of the base 1, wherein a cooling water pipe is embedded inside the water-cooled plate 2, the cooling water pipe having an S-shaped structure and both ends extending out from one side of the water-cooled plate 2; a lower mold 3 fixedly connected to the top of the water-cooled plate 2, wherein a mold core 7 is embedded inside the lower mold 3, wherein a molding cavity 19 is opened at the top of the mold core 7, wherein an ejector pin 18 is raised and lowered inside the molding cavity 19, and movable insert 10 and movable insert 2 15 are slidably installed at both ends of the molding cavity 19 for forming the middle hole of the handle; a driving part is provided on the outside of the lower mold 3 for driving the movable insert 10 and movable insert 2 15 to reset and move; and an upper mold 4 placed on top of the lower mold 3.

[0026] It should be noted that in this embodiment, positioning pins are fixed to the four corners of the top of the lower mold 3, and positioning holes that cooperate with the positioning pins are opened at the bottom of the upper mold 4. The upper mold 4 is placed on top of the lower mold 3, and the positioning pins cooperate with the positioning holes to achieve mold closing. Then, the drive unit drives the movable insert 10 and movable insert 2 15 to insert into the molding cavity 19. After the injection molding machine finishes injecting glue, cold water is injected from one end of the cooling water pipe by the water pump. After circulating inside the water cooling plate 2, it flows out from the other end of the cooling water pipe. During this process, the water cooling plate 2 carries away the heat inside the lower mold 3, thereby forming the workpiece inside the lower mold 3. Then, the upper mold 4 separates from the lower mold 3. Then, the drive unit drives the movable insert 10 and movable insert 2 15 to be pulled out from the molding cavity 19, and then the movable insert 2 15 pushes the workpiece out of the molding cavity 19 upward.

[0027] In one embodiment, a needle plate 17 is slidably connected to the middle of the base 1, and a pin 18 is fixedly connected to the needle plate 17.

[0028] It should be noted that in this embodiment, a metal rod is installed at the bottom of the needle plate 17. The metal rod is connected to a hydraulic cylinder or other driving equipment. The hydraulic cylinder drives the needle plate 17 to move towards the forming cavity 19 through the metal rod, thereby ejecting and separating the workpiece in the forming cavity 19 through the ejector pin 18.

[0029] In one embodiment, the drive unit includes a first cylinder 8 symmetrically fixed to both sides of the lower mold 3 and a second cylinder 16 symmetrically fixed to both sides of the lower mold 3. The output end of the first cylinder 8 is fixedly connected to a connecting plate 9, and the connecting plate 9 is fixedly connected to the movable insert 10.

[0030] It should be noted that in this embodiment, the hydraulic cylinder 8 is fixedly connected to the lower mold 3 through the mounting bracket. The hydraulic cylinder 8 drives the two movable inserts 10 to slide inside the lower mold 3 through the connecting plate 9. This allows the workpiece to be formed under the action of the movable inserts 10 and the molding cavity 19 during injection molding. During demolding, the hydraulic cylinder 8 drives the movable inserts 10 to separate from the molding cavity 19 through the connecting plate 9, thereby facilitating the workpiece to cooperate with the ejector pin 18 for material removal.

[0031] In one embodiment, a groove 11 is provided on the top of the mold core 7. Two right-angled trapezoidal inclined plates 13 are symmetrically slidably connected inside the groove 11. The inclined plates 13 are fixedly connected to the movable insert 15. A spring 14 is sleeved on the outside of the movable insert 15 and located between the groove 11 and the inclined plates 13. A drive plate 12 is fixedly connected to the output end of the hydraulic cylinder 16. The drive plate 12 is slidably connected to the inclined surface of the inclined plate 13.

[0032] It should be noted that, in this embodiment, after the mold is closed, the piston rod of the second hydraulic cylinder 16 extends and drives the drive plate 12 to slide inside the slide groove 11. During the movement of the drive plate 12, it contacts the inclined plate 13. The drive plate 12 pushes the inclined plate 13 to move towards the end of the slide groove 11. The inclined plate 13 drives the second movable insert 15 to move into the molding cavity 19. While the inclined plate 13 is moving, it compresses the spring 14, so that the second movable insert 15 is inserted into the molding cavity 19. Through the cooperation of the second movable insert 15 and the first movable insert 10, the end of the workpiece is made into a tubular structure. When the second hydraulic cylinder 16 drives the drive plate 12 to reset, the spring 14 drives the second movable insert 15 to reset through the inclined plate 13.

[0033] In one embodiment, the bottom of the upper mold 4 is fitted with a mold cavity 6 that mates with the mold core 7, the bottom of the mold cavity 6 is provided with a cavity that mates with the molding cavity 19, and the top of the upper mold 4 is fixedly connected with a top plate 5, and the top of the top plate 5 is fixedly connected with an injection hole.

[0034] It should be noted that, in this embodiment, when the upper mold 4 and the lower mold 3 are closed, the cavity 19 and the cavity 6 of the mold form a glue injection molding space. The injection molding machine injects glue through the glue injection hole, which enters the cavity 19 through the internal flow channel of the upper mold 4, thereby completing the injection molding.
