[0019] Example

[0020] like Figure 1-4As shown, this utility model proposes an automotive injection mold with a cooling structure, including a shell 1, a cooling mechanism 2 disposed inside the shell 1, and an annular cavity formed inside the shell 1. The cooling mechanism 2 is installed correspondingly to the annular cavity. The cooling mechanism 2 includes a coolant tank 21, the mounting end of which is installed correspondingly to the inner wall of the cavity and is fixedly connected to the inner wall of the annular cavity. A pipe mounting plate 28 is disposed above the coolant tank 21, the mounting end of which is installed correspondingly to the top of the coolant tank 21 and is fixedly connected to the coolant tank 21. A water pump 22 is disposed on the coolant tank 21, the mounting end of which is installed correspondingly to one side of the coolant tank 21 and is fixedly connected to the coolant tank 21. The water pump 22 is fixedly connected to the coolant tank 21. The suction port of the water pump 22 is located inside the coolant tank 21. The installation end of the water pump 22 is fixedly connected to the coolant tank 21. The outlet end of the water pump 22 is connected to an annular synchronizing pipe 23. The water pump 22 is configured to draw coolant from the coolant tank 21 into the annular synchronizing pipe 23. The installation end of the annular synchronizing pipe 23 is installed correspondingly to the top of the coolant tank 21 and is fixedly connected to the top of the coolant tank 21. Multiple sets of connecting pipes 24 are provided on the inner ring of the annular synchronizing pipe 23 above the coolant tank 21. Multiple sets of connecting holes are circumferentially opened on the annular synchronizing pipe 23. One end of each connecting pipe 24 is installed corresponding to a connecting hole. The mounting end is fixedly connected to the connecting hole. Each set of connecting pipes 24 has a conveying pipe 25 at one end. The conveying pipe 25 is arranged in a "Z" shape, with one end of the conveying pipe 25 corresponding to one end of the connecting pipe 24. The conveying pipe 25 is fixedly connected to the connecting pipe 24 and fits snugly against the outer side of the pipe mounting plate 28. The mounting end of the conveying pipe 25 is fixedly connected to the outer side of the pipe mounting plate 28. The conveying pipe 25 increases the cooling area, thus better cooling the injection mold and facilitating demolding. A connecting pipe 26 is provided at the end of the conveying pipe 25 away from the connecting pipe 24. The other end of the conveying pipe 25 is correspondingly installed with one end of the connecting pipe 26. One end of the connecting pipe 26 is connected to the conveying pipe 25. One end is fixedly connected, and one end of the connecting pipe 26 is provided with a cooling plate 27. Each group of cooling plates 27 has a connection port on its outer side. The end of the connecting pipe 26 away from the conveying pipe 25 is installed with the connection port. The other end of the connecting pipe 26 is fixedly connected to the connection port on the cooling plate 27. The inner side of each group of cooling plates 27 is set in a stepped shape at the middle position. Multiple groups of cooling plates 27 are stacked in a ring shape. The setting of multiple groups of cooling plates 27 can absorb and cool down the temperature of the injection molding on the module 3. The setting of the cooling mechanism 2 can greatly improve the cooling efficiency of the car knob mold. At the same time, the setting of multiple groups (27) in a ring shape can make the mold cool more evenly during the cooling operation, so that the operator can quickly demold the car knob and improve production efficiency.

[0021] The inner ring of the outer shell 1 is provided with a module 3, which includes a top mold 31 and a bottom mold 32. The outer circumferences of the top mold 31 and the bottom mold 32 are fitted together with the inner ring of the outer shell 1. The outer circumference of the bottom mold 32 is fixedly connected to the inner ring of the outer shell 1. The top mold 31 and the bottom mold 32 are tightly fitted together on one side. When the top mold 31 and the bottom mold 32 are in the assembled state, the injection groove is closed. Multiple sets of guide rods 33 are provided on the side of the top mold 31 near the bottom mold 32. One end of the guide rod 33 is installed corresponding to one side of the top mold 31 and is fixedly connected to the top mold 31. Multiple sets of positioning holes 36 are provided on one side of the bottom mold 32. The guide rods 33 are installed corresponding to the positioning holes 36 and are slidably connected to the positioning holes 36. The setting of the guide rods 33 and the positioning holes 36 can limit and guide the top mold 31 and the bottom mold 32 during the assembly operation, thereby avoiding misalignment between the top mold 31 and the bottom mold 32. In the event of misalignment causing injection failure, two sets of demolding handles 34 are provided on the top of the mold 31. The mounting ends of the demolding handles 34 are installed corresponding to the upper side of the mold 31, and the demolding handles 34 are fixedly connected to the mold 31. The demolding handles 34 facilitate the operator to quickly detach the mold 31 from the mold 32. The mold 31 is provided with an injection port 35 and an injection hole. The mounting ends of the injection port 35 are located at the injection hole position and are installed corresponding to the side of the mold 31, and the mounting ends of the injection port 35 are fixedly connected to the mold 31. The injection port 35 facilitates the operator's injection operation. The module 3 can be used to injection mold automotive knobs. At the same time, the cooling mechanism 2 can cool the molded knob mold after injection molding, thereby facilitating the operator to quickly demold the mold and improve production efficiency.

[0022] In this embodiment, the operator first inserts the top mold 31 above the bottom mold 32, guided by the guide rod 33 corresponding to the positioning hole 36, so that the top mold 31 and the bottom mold 32 are assembled. Then, the operator performs injection molding into the module 3 through the injection port 35. After the injection molding is completed, the operator starts the water pump 22. The water pump 22 draws the coolant in the coolant tank 21 into the annular synchronous pipe 23. The coolant in the annular synchronous pipe 23 is transported to the delivery pipe 25 through the connecting pipe 24, and then to the cooling plate 27 through the connecting pipe 26 to absorb heat, thereby cooling the injection area. When the mold temperature drops to the demolding temperature, the operator lifts the top mold 31 through the demolding handle 34, so that the top mold 31 and the bottom mold 32 are separated from the assembly state. Then the mold can be removed, completing the injection molding and demolding of the car knob.

[0023] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
