An injection molding orientation device comprises a processing box 1, a cylinder 2 is fixedly connected to one side of the processing box 1, and a connecting rod 3 is fixedly connected to the piston rod of the cylinder 2.

[0024] In the specific implementation process, Figure 1 , Figure 2 and Figure 3 As shown, the control component 4 is arranged on the inner side of the processing box 1, and the control component 4 includes a support frame 41, a moving plate 42 and a fixed block 43.

[0026] The inner side of the support frame 41 is fixedly connected with a support block 6 , and the inner side of the support block 6 is slidably connected with a support rod 7 .

[0027] One end of the support rod 7 is fixedly connected to a positioning plate 8, the outer side of the support rod 7 is fixedly connected to a first support plate 9, one end of the support rod 7 is fixedly connected to the moving plate 42, and the outer side of the support rod 7 is fixedly connected to a second support plate 11.

[0028] A first mold 10 is fixedly connected to one side of the first support plate 9 , and a second mold 12 is fixedly connected to one side of the second support plate 11 . Heating tubes 13 are disposed inside the first mold 10 and the second mold 12 .

[0029] It should be noted that: under the drive of the cylinder 2, the connecting rod 3 drives the moving plate 42 to move under the support of the support rod 7, and under the action of the support rod 7, the positioning plate 8 is pushed to move, and under the fixation of the first support plate 9, the first mold 10 is driven to move. At the same time, under the connection of the fixed block 43, the connecting plate 45 near the moving plate 42 pushes the control frame 44 to rotate under the support and fixation of the support frame 41, so that the connecting plate 45 near the second mold 12 pulls the second support plate 11 to move, thereby pulling the second mold 12 to move, so that the first mold 10 and the second mold 12 are connected. The two molds 12 show an opening and closing movement.

[0030] refer to Figure 1 and Figure 4 As shown, the temperature control component 5 is arranged inside the processing box 1, and the temperature control component 5 includes a mounting frame 51 and a liquid storage box 52. The mounting frame 51 is fixedly connected to the inside of the processing box 1, and the inner side of the mounting frame 51 is fixedly connected to the liquid storage box 52.

[0031] The temperature control component 5 further includes a water pump 53 and a delivery pipe 54 . The water pump 53 is fixedly connected to the inner side of the mounting frame 51 , and the water outlet of the water pump 53 is connected to the delivery pipe 54 .

[0032] The water inlet of the water pump 53 is communicated with the interior of the liquid storage box 52 , and one end of the delivery pipe 54 is communicated with the interior of the liquid storage box 52 .

[0033] A fan 14 is disposed inside the processing box 1 , and a through hole 15 and a through slot 16 are respectively opened inside the processing box 1 .

[0034] It should be noted that the liquid storage box 52, the water pump 53 and the delivery pipe 54 are fixed by the mounting frame 51. Driven by the water pump 53, the coolant in the liquid storage box 52 flows in the delivery pipe 54, effectively reducing the ambient temperature. The fan 14 is started, and under the action of the through groove 16, the cooled air is blown to the surroundings of the first mold 10 and the second mold 12, which is beneficial to quickly reduce the mold cavity temperature, allowing the magnetic material to cool and solidify, which is beneficial to maintaining the degree of orientation and obtaining an injection molded magnet with a high degree of orientation.

[0035] The working principle of an injection molding orientation device provided by the utility model is as follows:

[0036] When in use, under the action of the cylinder 2, the moving plate 42 is driven to move through the connecting rod 3, and under the action of the support rod 7, the fixed block 43 drives the connecting plate 45 to move, thereby pushing the control frame 44 to rotate, pulling another connecting plate 45 to drive the second support plate 11 to move, thereby controlling the movement of the second mold 12. At the same time, under the action of the moving plate 42, the support rod 7 drives the positioning plate 8 to move, and then drives the first mold 10 to move under the support of the first support plate 9. When the connecting rod 3 pushes, the first mold 10 and the second mold 12 move away from each other. When the connecting rod 3 is reset, the first mold 10 and the second mold 12 contact, controlling the first mold 10 and the second mold 12 to move. The two molds 12 are in contact to form a mold cavity, and magnetic material is injected into the mold cavity. Under the action of the heating tube 13, the mold cavity is heated, which is beneficial to reduce the adhesion between the magnetic powders and facilitate mold filling, orientation and magnetization. After closing the heating tube 13, the coolant in the liquid storage box 52 circulates in the delivery pipe 54 under the drive of the water pump 53, which is beneficial to achieve rapid cooling. Under the action of the fan 14 and the through groove 16, the cooled air is blown to the first mold 10 and the second mold 12, so that the molten material in the mold cavity is solidified, which is convenient for obtaining injection molded magnets with high orientation, and is conducive to processing into high-quality injection molded magnets, thereby promoting the development of the injection molded magnet industry.
