[0005] Preferably, the hydraulic cylinder is located at the upper end of the top frame, the output end of the hydraulic cylinder is fixedly connected to the upper surface of the upper mold, and the guide sleeve is slidably connected to the guide rod. Here, the upper mold is pushed by the hydraulic cylinder to realize the opening and closing of the mold. Through the design of the guide sleeve and the guide rod, the upper mold can be guided during the injection molding process to ensure that the closing and opening of the upper mold are stable and accurate.

[0006] Preferably, the suction end of the water pump extends to the water tank, one end of the connecting pipe extends to the interior of the lower mold, and one end of the circulation pipe extends to the interior of the water tank. Here, the coolant in the water tank is extracted by the water pump and transported to the interior of the lower mold through the connecting pipe, so that the injection mold can be cooled, and the water is transported to the interior of the water tank again through the circulation pipe to realize the water circulation effect, thereby improving the working efficiency of the injection mold.

[0007] Preferably, the output end of the motor is fixedly connected to one end of the rotating shaft 1. Here, the rotating shaft 1 is driven by the motor to rotate, so that the air is evenly blown to the surface of the injection molded part through the fan blades, which can promote the uniformity of the temperature of the entire injection molded part and accelerate the cooling of the surface of the injection molded part, thereby effectively enhancing the heat dissipation capacity and improving production efficiency and product quality.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

Through water cooling and air cooling, the injection molding device can achieve rapid, uniform and efficient heat dissipation, thereby optimizing the injection molding process and improving product quality. At the same time, the upper mold can be guided during the injection molding process to ensure that the closing and opening of the upper mold are stable and accurate, thereby significantly improving production efficiency.

[0013] 2. In the utility model, by setting a limit hole, a mounting plate, a limit rod, a limit disk and a spring B, the positioning rod can be quickly disassembled and replaced. The outer wall of the positioning rod will be worn after multiple mold closings. When the mold is closed again due to severe wear, a large gap will be generated when the positioning rod is embedded in the lower mold. This will reduce the accuracy of the mold closing and cause the mold to fail to close normally. In addition, since the existing positioning rod is integrally processed with the mold, it is inconvenient to replace it and a new mold needs to be manufactured for injection molding production, thereby effectively avoiding extending the production time and increasing the production cost.

[0025] See also Figure 1-4 The hydraulic cylinder 3 is located at the upper end of the top frame 2, and the output end of the hydraulic cylinder 3 is fixedly connected to the upper surface of the upper mold 4. The guide sleeve 6 and the guide rod 7 are slidably connected. The hydraulic cylinder 3 pushes the upper mold 4 to realize the opening and closing of the mold. Through the design of the guide sleeve 6 and the guide rod 7, the upper mold 4 can be guided during the injection molding process to ensure that the closing and opening of the upper mold 4 are stable and accurate. The suction end of the water pump 10 extends to the water tank 8, one end of the connecting pipe 11 extends to the inside of the lower mold 5, and one end of the circulation pipe 12 extends to the inside of the water tank 8. The coolant in the water tank 8 is extracted by the water pump 10 and transported to the inside of the lower mold 5 through the connecting pipe 11, so that the injection mold can be cooled and the cooling liquid is discharged through the circulation pipe 12. The water is transported to the inside of the water tank 8 again to realize the water circulation effect, thereby improving the working efficiency of the injection mold. The output end of the motor 20 is fixedly connected to one end of the rotating shaft 14, and the rotating shaft 14 is driven by the motor 20 to rotate, so that the air is evenly blown to the surface of the injection molded part through the fan blades 16, which can promote the temperature uniformity of the entire injection molded part and accelerate the cooling of the surface of the injection molded part, thereby effectively enhancing the heat dissipation capacity and improving production efficiency and product quality.

Example

[0026] See also Figure 5-6 A limiting hole 24 is provided on the side of the positioning sleeve 21, and a mounting plate 25 is fixedly installed on the side of the upper mold 4. A limiting rod 26 is slidably connected inside the mounting plate 25, and a limiting disk 27 is fixedly installed on the surface of the limiting rod 26. A spring B28 is fixedly installed on the side of the limiting disk 27, so that the positioning rod 23 can be quickly replaced, avoiding the outer wall of the positioning rod 23 from being worn after the upper mold 4 and the lower mold 5 are molded multiple times, which will cause a large gap when the positioning rod 23 is embedded in the lower mold 5 when the mold is closed again, resulting in failure to close the mold normally, thereby improving production efficiency. The limiting rod 26 is slidably connected to the limiting hole 24, and one end of the spring B28 is fixedly connected to the inner side of the mounting plate 25. The positioning sleeve 21 is fixed and stuck inside the upper mold 4 through the limiting rod 26. The design of the spring B28 facilitates the disassembly of the positioning sleeve 21.

[0027] Working principle: When it is necessary to inject medical devices, the hydraulic cylinder 3 is first started. The output end of the hydraulic cylinder 3 will drive the upper mold 4 to move. At this time, the upper mold 4 will drive the guide sleeve 6 to slide on the surface of the guide rod 7, thereby guiding the upper mold 4 to ensure that the closing and opening of the upper mold 4 are stable and accurate. When it moves to a certain position, the positioning rod 23 installed on the lower surface of the upper mold 4 will slide into the lower mold 5, thereby further improving the accuracy of the guidance. When the positioning rod 23 moves to a certain position, the spring A22 will be compressed, and the spring A22 set on the positioning rod 23 will be compressed. The spring A22 can provide a certain buffer force, thereby reducing the wear of the upper mold 4 during the opening and closing process. After the mold is closed, injection molding can be carried out. At this time, the water pump 10 is started, and the suction end of the water pump 10 absorbs the coolant from the inside of the water tank 8, and then transports it to the inside of the lower mold 5 through the connecting pipe 11, so that it can quickly absorb and take away the heat on the surface and inside of the injection molded part. The coolant that absorbs the heat flows into the water tank 8 through the circulation pipe 12. The cooling plate 9 set in the water tank 8 can cool the coolant flowing in again. At the same time, the operator can start the motor 20, and the motor 20 will bring The rotating shaft 14 and the pulley 17 are rotated. Since the pulley 17 and the pulley 2 18 are connected by a transmission belt, the rotating shaft 2 15 is rotated to make the fan blades 16 rotate, so that the air is evenly blown to the surface of the injection molded part through the fan blades 16, thereby accelerating the heat dissipation of the injection molded part. When the outer wall of the positioning rod 23 is worn due to multiple mold closing and needs to be replaced, first pull the limiting rod 26 to make it slide out of the limiting hole 24 opened in the positioning sleeve 21. At this time, the positioning sleeve 21 and the positioning rod 23 can be pulled out from the inside of the upper mold 4. When reinstalling, pull the limiting rod 26 first. The spring B28 of the positioning rod 26 is compressed at the same time, and then the positioning sleeve 21 is slid into the interior of the upper mold 4. At this time, the limiting rod 26 is released. The limiting rod 26 will be tightly attached to the outside of the positioning sleeve 21 under the action of the spring B28. At this time, the positioning sleeve 21 can be rotated. When the limiting rod 26 is in the same position as the limiting hole 24 opened in the positioning sleeve 21, the limiting rod 26 will automatically slide into the interior, so that the positioning sleeve 21 is fixed and stuck in the interior of the upper mold 4, so that the positioning rod 23 can be quickly disassembled and replaced without manufacturing a new mold for injection molding production, which effectively avoids extending the production time and increasing the production cost.
