Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a split injection mold. Background Technology

[0002] Injection molds are essential tools in the plastics processing industry for producing plastic products. They are used by an injection molding machine to inject molten plastic into a mold cavity, where it cools to obtain the desired plastic product shape.

[0003] In the prior art, a search revealed a Chinese patent disclosure entitled "A Split-Type Injection Mold," application number "202323383724.2." This patent mainly includes a base plate, with a cooling mechanism fixed to the top of the base plate. An injection cavity is formed at the top of the cooling mechanism. Connecting shafts are provided on both sides of the base plate, with screws fixed to the top of the connecting shafts. A top plate is fixed to the outer sides of the two screws, and a moving mold is fixed to the bottom of the top plate. The moving mold cooperates with the injection cavity. The cooling mechanism includes a fixed mold with an internal cavity for holding coolant. A connecting rod is rotatably connected inside the fixed mold, with multiple cooling blades fixed to the outer sides of the connecting rod. Fan blades are rotatably connected to both ends of the connecting rod inside the fixed mold, located above it. One end of a support rod and both ends of the connecting rod extend out of the fixed mold and are connected to the connecting shaft by a connecting piece. While this invention can improve the efficiency of mold cooling and shaping, it is not universally applicable. However, after the coolant completes heat exchange inside the mold, its temperature rises significantly. Relying solely on the vent pipe to allow the cooled coolant to contact the outside air for heat dissipation is inefficient. This is because the natural convection and thermal conductivity of air are limited, making it difficult to effectively remove the large amount of heat from the coolant in a short time. This may result in the coolant not being adequately cooled during circulation, thus affecting the overall cooling effect of the mold. Therefore, this invention provides a split-type injection mold to solve the problems mentioned in the background section. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model discloses a split injection mold, which includes a fixed mold 1, a movable mold 3 disposed above the fixed mold 1, and an injection cavity 2 disposed inside the fixed mold 1. Multiple cooling pipes 4 are uniformly fixedly connected to the inner wall of the injection cavity 2 to ensure efficient heat exchange. Both ends of the cooling pipes 4 are fixedly connected to inlet pipes 5, and one end of adjacent inlet pipes 5 is fixedly connected to a first connecting pipe 6. A cooling box 8 is provided on one side of the fixed mold 1, and a water pump 12 is provided between the cooling box 8 and the fixed mold 1. One side of the water pump 12 is fixedly connected to a water pipe 13 connected to the first connecting pipe 6. The water pump 12 and the cooling box 8 are connected by a pipe. Additionally, one end of adjacent inlet pipes 5 is fixedly connected to a second connecting pipe 7, which is connected to the cooling box 8.

[0024] When the water pump 12 starts, the coolant flows into the first connecting pipe 6 through the water supply pipe 13, and then is distributed to the cooling pipe 4 for cooling. The second connecting pipe 7 is connected to the cooling tank 8 to realize the return of the coolant, thus achieving a high-efficiency and uniform cooling effect.

[0025] A first rotating shaft 10 is rotatably connected inside the cooling box 8. Multiple stirring blades 9 are evenly fixedly connected to the outer side of the first rotating shaft 10. A radiator 11 is embedded on one side of the cooling box 8. A fixing frame 21 is fixedly connected to the side of the cooling box 8 near the radiator 11. A fourth rotating shaft 24 is rotatably connected inside the fixing frame 21. A fan blade 23 is fixedly connected to the end of the fourth rotating shaft 24 away from the radiator 11. A mounting frame 25 is fixedly connected to the side of the moving mold 3 near the cooling box 8. A rack 15 is fixedly connected to the bottom of the mounting frame 25. A gear 15 is fixedly connected to one end of the first rotating shaft 10. The transmission gear 14 is meshed with the first shaft 10 and the fourth shaft 24. A transmission assembly for driving the fourth shaft 24 to rotate is provided between the first shaft 10 and the fourth shaft 24. The transmission assembly includes a fixed plate 18 fixedly connected to the outside of the cooling box 8, a second shaft 19 rotatably connected to the inside of the fixed plate 18, and a third shaft 22 rotatably connected to the inside of the fixed frame 21. A bevel gear 20 is fixedly connected to the outside of the first shaft 10, both ends of the second shaft 19, both ends of the third shaft 22, and the end of the fourth shaft 24 near the radiator 11. Every two adjacent bevel gears 20 mesh with each other.

[0026] When the moving mold 3 moves up and down, the mounting bracket 25 drives the rack 15 to move up and down. The rack 15 drives the transmission gear 14, which meshes with it, to rotate, thereby driving the first rotating shaft 10 to rotate. The stirring blade 9, following the rotation of the first rotating shaft 10, can effectively stir the coolant, improving the cooling efficiency of the coolant. The rotation of the first rotating shaft 10 synchronously drives the bevel gear 20 on it to rotate. Under the meshing action of the second rotating shaft 19, the third rotating shaft 22, the fourth rotating shaft 24, and the bevel gear 20, the fan blade 23 can rotate. When the radiator 11 dissipates the heat from the coolant into the air, the rotating fan blade 23 enhances the airflow near the radiator 11, further improving the cooling efficiency of the coolant. This allows the coolant to reach the ideal temperature range more quickly, thus reducing the energy consumed by the semiconductor cooling chip 17 and achieving a certain energy-saving effect.

[0027] To further improve the cooling effect, a semiconductor cooling chip 17 is embedded on one side of the cooling box 8, and a temperature sensor 16 is fixedly connected to the inner wall of the cooling box 8. The semiconductor cooling chip 17 operates according to the coolant temperature detected by the temperature sensor 16 to ensure that the coolant is always kept within the optimal operating temperature range.

[0028] The cooling pipe 4 is made of copper, which makes the cooling pipe 4 have better thermal conductivity. The radiator 11 is made of aluminum, which can quickly dissipate the heat in the coolant into the air.

[0029] Working principle: When the water pump 12 starts, the coolant flows into the first connecting pipe 6 through the water supply pipe 13, and then is distributed to the cooling pipe 4 for cooling. The second connecting pipe 7 is connected to the cooling tank 8 to realize the return of the coolant, thus achieving a high-efficiency and uniform cooling effect.

[0030] When the moving mold 3 moves up and down, the mounting bracket 25 drives the rack 15 to move up and down. The rack 15 drives the transmission gear 14, which meshes with it, to rotate, thereby driving the first rotating shaft 10 to rotate. The stirring blade 9, following the rotation of the first rotating shaft 10, can effectively stir the coolant, improving the cooling efficiency of the coolant. The rotation of the first rotating shaft 10 synchronously drives the bevel gear 20 on it to rotate. Under the meshing action of the second rotating shaft 19, the third rotating shaft 22, the fourth rotating shaft 24, and the bevel gear 20, the fan blade 23 can rotate. When the radiator 11 dissipates the heat from the coolant into the air, the rotating fan blade 23 enhances the airflow near the radiator 11, further improving the cooling efficiency of the coolant. This allows the coolant to reach the ideal temperature range more quickly, thus reducing the energy consumed by the semiconductor cooling chip 17 and achieving a certain energy-saving effect.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
