[0021] 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.
[0022] Please see Figure 1-5 This utility model provides an embodiment of a charger housing molding die, comprising an upper mold 1, a lower mold 2, three-layer annular cooling water pipes 3, and a pusher mechanism 4. Guide pillars are fixedly connected to the four corners of the lower mold 2, and the guide pillars of the lower mold 2 are slidably connected to the upper mold 1. Nine mold core cavities 11 are opened at the top of the upper mold 1. Nine three-layer annular cooling water pipes 3 are fixedly connected inside the upper mold 1, and the positions of the three-layer annular cooling water pipes 3 correspond to the positions of the mold core cavities 11. Two injection grooves 12 are opened at the top of the upper mold 1. The pusher mechanism 4 is provided with nine... The ejector mechanism 4 includes a support rod 41, which is fixedly connected to the inner wall of the lower mold 2. The support rod 41 is slidably connected to a support rod 43, and a bracket 46 is fixedly connected to the top of the support rod 43. Push plates 47 are fixedly connected to both the front and rear ends of the top of the bracket 46. The inner wall of the mold cavity 11 can be quickly cooled by the three-layer annular cooling water pipes 3, thereby improving processing efficiency and facilitating subsequent demolding. The ejector mechanism 4 can automatically push out the outer shell when the upper mold 1 is detached, without the need for manual demolding, making it convenient and quick to use.
[0023] Furthermore, the inner walls at both ends of the mold cavity 11 are provided with slots 13. The top of the push plate 47 is slidably connected to the slots 13. When the upper mold 1 moves downward, the inner wall of the slots 13 of the upper mold 1 pushes the push plate 47 downward, causing the spring 45 to be compressed and contract.
[0024] Furthermore, nine cores 21 are fixedly connected to the top of the lower mold 2, and two injection grooves 22 are opened on the top of the lower mold 2. The cylinder drives the upper mold 1 to move downward, so that the upper mold 1 is inserted into the lower mold 2. The outer shell shape is formed by the cooperation of the mold cavity 11 and the cores 21. Molten plastic is injected into the upper mold 1 and the lower mold 2 through the injection grooves 1 and 22.
[0025] Furthermore, the lower mold 2 has nine sliding grooves 24 inside, and the bracket 46 slides up and down in the sliding grooves 24. The front and rear sides of the inner wall of the sliding grooves 24 are provided with slots 23. The bottom of the push plate 47 is slidably connected to the slots 23. When the support rod 43 retracts into the support rod 41, the push plate 47 is inserted into the slots 23.
[0026] Furthermore, the two three-layer annular cooling water pipes 3 are connected by a connecting pipe 31. The right side of the rightmost three-layer annular cooling water pipe 3 is fixedly connected to the inlet pipe 32, and the left side of the leftmost three-layer annular cooling water pipe 3 is fixedly connected to the outlet pipe 33. Coolant is injected into the three-layer annular cooling water pipe 3 through the inlet pipe 32, and the coolant cools the inner wall of the mold cavity 11, thereby achieving rapid shaping of the outer shell.
[0027] Furthermore, the front and rear sides of the support rod 41 are provided with sliding grooves 42, and the front and rear sides of the support rod 43 are fixedly connected with sliding rods 44. The sliding rods 44 slide up and down in the sliding grooves 42, and the sliding rods 44 play a limiting role. The sliding rods 44 prevent the support rod 43 from detaching from the support rod 41, and make the sliding of the support rod 43 more stable, thus improving stability.
[0028] Furthermore, a spring 45 is fitted inside the support rod 41. One end of the spring 45 abuts against the inner wall of the support rod 41, and the other end of the spring 45 abuts against the outer wall of the support rod 43. The push plate 47 moves downward, causing the spring 45 to contract under pressure. The cylinder drives the upper mold 1 to move upward, and the elastic force of the spring 45 pushes the bracket 46 and the push plate 47 to move upward, causing the push plate 47 to push out the outer shell.
[0029] Working principle:
[0030] During operation, the cylinder drives the upper mold 1 downwards, allowing it to engage with the lower mold 2. Molten plastic is injected into both molds through injection groove 12 and injection groove 22. After injection molding, coolant is injected into the three-layer annular cooling water pipe 3 through the water inlet pipe 32. The coolant cools the inner wall of the mold cavity 11, achieving rapid shell shaping. The three-layer annular cooling water pipe 3 provides rapid cooling of the inner wall of the mold cavity 11, improving processing efficiency and facilitating subsequent demolding. When the upper mold 1 moves downwards, the slot 13 of the upper mold 1... The inner wall pushes the push plate 47 downward, causing the spring 45 to contract under pressure, which in turn causes the support rod 43 to retract into the support rod 41, and the push plate 47 to insert into the slot 23. After the injection molding of the outer shell is completed, the cylinder drives the upper mold 1 to move upward, and the elastic force of the spring 45 pushes the bracket 46 and the push plate 47 upward, causing the push plate 47 to push the outer shell out. Through the large-area contact between the push plate 47 and the outer shell, the stability of the outer shell demolding is improved, and the outer shell will not be damaged. The push mechanism 4 can automatically push the outer shell out when the upper mold 1 is detached, without the need for manual demolding, which is convenient and quick to use.
