Detailed Implementation

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] According to one embodiment of the present invention, in conjunction with Figures 1-6 The diagram shows an air conditioner outdoor unit injection molding equipment, including a workbench 1 and a support leg 14 fixedly connected to the bottom of the workbench 1. A connecting plate 12 is fixedly connected to one side of the workbench 1, a support plate 121 is fixedly connected to the top of the connecting plate 12, a top plate 1211 is fixedly connected to the top of the support plate 121, an upper mold 4 is provided below the top plate 1211, a lower mold 5 is provided at the top of the workbench 1, a cooling box 2 is provided at the bottom of the workbench 1, and a cooling component 3 is provided inside the cooling box 2.

[0025] In this embodiment, the cooling assembly 3 includes a mounting plate 31 fixedly connected to the inner wall of the cooling box 2, a first motor 32 mounted on one side of the mounting plate 31, a rotating shaft 321 fixedly connected to the output end of the first motor 32, a mounting base 33 fixedly connected to one end of the rotating shaft 321, a fan blade 331 fixedly connected to the outer surface of the mounting base 33, a partition 34 fixedly connected to the inner wall of the cooling box 2, a vent 341 opened on the outer surface of the partition 34, a cooling pipe 35 fixedly penetrating the cooling box 2, an air pump 36 mounted on the top of the workbench 1, a first air pipe fixedly connected to the input end of the air pump 36, a second air pipe 361 fixedly connected to the output end of the air pump 36, a branch pipe 37 fixedly connected to one end of the second air pipe 361, a connecting pipe 38 fixedly connected to the outer surface of the branch pipe 37, and a blower hood 39 fixedly connected to one end of the connecting pipe 38. The first air pipe is fixedly connected to the cooling box 2. External coolant is introduced into the cooling pipe 35. As the coolant flows inside the cooling pipe 35, it absorbs heat from the surrounding environment, thereby reducing its temperature. The first motor 32 drives the rotating shaft 321 and the mounting base 33 to rotate, which in turn drives the fan blades 331 to rotate. The rotation of the fan blades 331 generates airflow. This airflow is blown onto the cooling pipe 35 through the vents 341 on the outer surface of the partition 34, increasing the airflow speed around the cooling pipe 35. The air pump 36 is started, which draws the cooled air out of the cooling box 2 and transmits it to the blower shroud 39 in sequence through the first air pipe, the second air pipe 361, the split pipe 37, and the connecting pipe 38. The blower shroud 39 blows air directly onto the lower mold 5 to effectively reduce the temperature of the lower mold 5.

[0026] A baffle 34 is positioned above the fan blades 331, and a cooling pipe 35 is positioned above the baffle 34. A vent 11 is provided at the top of the workbench 1, and the vent 11 is connected to the cooling box 2. After the coolant in the cooling pipes 35 lowers the temperature of the surrounding air, the fan blades 331 rotate to blow the cold air, causing the cold air to concentrate and flow upwards, and directly act on the lower mold 5 through the vent 11 at the top of the workbench 1. This achieves directional delivery of the cold air flow, allowing the cold air to cover the outer surface of the lower mold 5 in a more uniform manner, further improving the cooling effect.

[0027] A groove 13 is provided at the top of the workbench 1. A second motor 6 is installed on one side of the workbench 1. A threaded rod 61 is fixedly connected to the output end of the second motor 6. A slider 611 is threadedly connected to the outer surface of the threaded rod 61. A connecting block 391 is fixedly connected to the bottom end of the blower shroud 39. The slider 611 is fixedly connected to the connecting block 391. One end of the threaded rod 61 is rotatably connected to the inner wall of the groove 13, and the other end of the threaded rod 61 rotatably passes through the groove 13. The second motor 6 drives the threaded rod 61 to rotate. The rotation of the threaded rod 61 drives the slider 611 to move along the axis of the threaded rod 61, thereby moving the connecting block 391 and the blower shroud 39. This allows the blower shroud 39 to cover a larger area, rather than being limited to cooling a fixed position. This helps to achieve comprehensive and uniform cooling of the lower mold 5.

[0028] The slider 611 is slidably connected to the groove 13, and the connecting tube 38 is a flexible tube. The sliding connection between the slider 611 and the groove 13 ensures that the blower cover 39 maintains a straight line during movement and prevents deviation from the track. The connecting tube 38 adopts a flexible tube design, which allows the blower cover 39 to move freely with the slider 611 without restricting the movement range of the blower cover 39 or affecting its normal operation.

[0029] A connecting frame 7 is provided at the bottom of the cooling box 2, and a filter plate 71 is fixedly connected inside the connecting frame 7. The outer surface of the filter plate 71 has filter holes 711. The filter holes 711 facilitate the filtration of dust, particulate matter and other impurities carried in the air, ensuring that the air entering the cooling box 2 is cleaner.

[0030] A first threaded hole 21 is provided at the bottom of the cooling box 2, and a second threaded hole 72 is provided on the outer surface of the connecting frame 7. A locking bolt 8 is threadedly connected between the first threaded hole 21 and the second threaded hole 72. The locking bolt 8 is passed through the second threaded hole 72 and connected to the first threaded hole 21 to facilitate fixing the filter plate 71 to the bottom of the cooling box 2. When it is necessary to clean the filter plate 71, the locking bolt 8 can be removed.

[0031] An electric push rod 9 is installed at the bottom of the top plate 1211. The telescopic end of the electric push rod 9 is fixedly connected to the upper mold 4, and the top of the upper mold 4 is fixedly connected to the injection tube 41. The telescopic function of the electric push rod 9 facilitates the control of the up and down movement of the upper mold 4, thereby realizing automated mold opening and closing operations. The injection tube 41 is directly connected to the upper mold 4, which facilitates the injection of molten plastic into the mold cavity by external injection equipment through the injection tube 41.

[0032] One end of the cooling pipe 35 is fixedly connected to a water inlet pipe 351, and a first valve 3511 is fixedly connected to the outer surface of the water inlet pipe 351. The other end of the cooling pipe 35 away from the water inlet pipe 351 is fixedly connected to a water outlet pipe 352, and a second valve 3521 is fixedly connected to the outer surface of the water outlet pipe 352. The water inlet pipe 351 and the water outlet pipe 352 are respectively connected to external pipes. The first valve 3511 and the second valve 3521 facilitate independent control of the inflow and outflow of coolant. Coolant enters the cooling pipe 35 through the water inlet pipe 351 and is discharged from the water outlet pipe 352 after completing heat exchange. This circulating cooling method facilitates the continuous removal of heat from the area around the mold.

[0033] In use, the extension and retraction of the electric push rod 9 facilitates the control of the up and down movement of the upper mold 4, thereby realizing automated mold opening and closing operations. The injection pipe 41 is directly connected to the upper mold 4, allowing external injection equipment to inject molten plastic into the mold cavity through the injection pipe 41. External coolant enters the cooling pipe 35 through the water inlet pipe 351. The first valve 3511 is used to control the inflow and flow rate of the coolant. When the coolant flows inside the cooling pipe 35, it absorbs heat from the surrounding environment, thereby reducing its temperature. The first motor 32 drives the rotating shaft 321 and the mounting base 33 to rotate, thereby driving the fan blades 331 to rotate. The rotation of the fan blades 331 generates airflow. This airflow is blown towards the cooling pipe 35 through the vents 341 on the outer surface of the partition 34, increasing the airflow speed around the cooling pipe 35. The air pump 36 is started, which draws the cooled air from the cooling box 2. The air is extracted from the bottom and sequentially transmitted through the first air pipe, the second air pipe 361, the diverter pipe 37, and the connecting pipe 38 to the blower hood 39. The blower hood 39 blows air directly onto the lower mold 5 to effectively reduce the temperature of the lower mold 5. At the same time, the fan blades 331 rotate to blow cold air, causing the cold air to flow upward and directly act on the lower mold 5 through the air vent 11 at the top of the worktable 1. This achieves directional delivery of cold air, allowing the cold air to cover the outer surface of the lower mold 5 in a more uniform manner, further improving the cooling effect. The second motor 6 drives the threaded rod 61 to rotate, and the rotation of the threaded rod 61 drives the slider 611 to move along the axis of the threaded rod 61, thereby driving the connecting block 391 and the blower hood 39 to move. This allows the blower hood 39 to cover a larger area, rather than being limited to cooling in a fixed position. This helps to achieve comprehensive and uniform cooling of the lower mold 5.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
