The temperature control accuracy is low and there is a lack of effective feedback mechanism, resulting in poor extrusion process stability and failing to meet the production requirements of high-precision aluminum profiles.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figures 1-6 This utility model discloses a high-precision aluminum profile extrusion die temperature control device, including a base 1 and a crossbeam 2 connecting the base 1, and also includes an extrusion assembly 3, a die cavity assembly 4, a temperature adjustment assembly 5, and a discharge cooling assembly 6, wherein:

[0025] Mold cavity assembly 4 includes mold block 41, mold cylinder 42 welded to the middle of mold block 41, and plastic molding part 43 fixed to the opposite side of mold cylinder 42 by bolts;

[0026] Please refer to the appendix. Figure 4 and appendix Figure 5 The temperature control component 5 includes a temperature controller 51, a heater 52, an electromagnetic coil 53, an infrared temperature sensor 54, and a cooling component. The temperature controller 51 is electrically connected to the heater 52. The electromagnetic coil 53 is symmetrically arranged on one side of the heater 52 and is nested on the outside of the mold cylinder 42.

[0027] Please refer to the appendix. Figure 6The discharge cooling assembly 6 includes a discharge trough 61, one end of which abuts against the molding part 43. A spray disc 62 and an infrared temperature sensor 54 are provided directly above the discharge trough 61. The spray disc 62 is connected to the main pipe 63 through a pipe. The main pipe 63 is connected to the water pump 64 through a solenoid valve 66. The solenoid valve 66 is electrically connected to the temperature controller 51. Specifically, the water pump 64 is started to draw cold water from the cold water tank 65 and introduce it into the main pipe 64, which is then sprayed out by the spray disc 62 to continuously cool the molded part. The infrared temperature sensor 54 feeds back the cooling temperature of the molded part to the temperature controller 51. The temperature controller 51 controls the flow rate of cold water on the molded part by controlling the opening of the solenoid valve 66, thereby controlling the cooling temperature of the molded part.

[0028] Side columns 11 are welded onto the base 1. The side columns 11 are symmetrically arranged. The two ends of the crossbeam 2 are fixed to the side columns 11 by bolts. The crossbeam 2 is welded to the bottom of the mold block 41.

[0029] The mold block 41 includes a feeding trough 411 and a forming trough 412. The feeding trough 411 and the forming trough 412 are separated by a partition plate 44, and each is equipped with an infrared temperature sensor 54 directly above it. The mold cylinder 42 passes through the partition plate 44.

[0030] The cooling components include cooling pipes 55 and water guide pipes 56. The cooling pipes 55 are symmetrically arranged in the feed tank 411 and the forming tank 412, and are welded to the outer wall of the mold cylinder 42. The two ends of the cooling pipes 55 are connected to the water guide pipes 56.

[0031] One end of the upper water pipe 56 is located above the cold water pool 65, and one end of the lower water pipe 56 is connected to the cooling pipe 55 through the solenoid valve 66, and the other end is connected to the water pump 64. One end of the water pump 64 is connected to the cold water pool 65.

[0032] In this embodiment, when the heating temperature of the mold cylinder 42 fluctuates, the infrared temperature sensor 54 feeds back the temperature change to the temperature controller 51 in real time. When the actual temperature is lower than the set value, the temperature controller 51 increases the heating temperature of the heater 52 to rapidly raise the actual temperature. When the actual temperature is higher than the set value, the temperature controller 51 disconnects the heater 52, starts the water pump 64 and opens the solenoid valve 66, drawing cold water from the cold water tank 65 and introducing it into the cooling pipe 55 through the water guide pipe 56, which then circulates rapidly outside the mold cylinder 42 to cool it down, thus achieving high-precision control of the heating temperature of the mold cylinder 42. Example 2

[0033] Based on the above embodiment 1, please refer to the appendix. Figure 2 as well as Figure 3 The extrusion assembly 3 includes a hydraulic cylinder 31, which is fixed to one side of the side column 11 by bolts. One end of the hydraulic cylinder 31 is provided with a hydraulic column 32, which passes through the side column 11 and is slidably engaged.

[0034] One end of the hydraulic column 32 is fixed with an extrusion column 33 by bolts. A cylindrical blank 7 is provided on one side of the extrusion column 33 along the axial direction. The cylindrical blank 7 is placed on the arc plate 34 and is directly opposite the opening of the mold cylinder 42.

[0035] In this embodiment, the cylindrical blank 7 is placed on the arc plate 34, and the hydraulic cylinder 31 is activated. The hydraulic cylinder 31 causes the hydraulic column 32 to move, which in turn drives the extrusion column 33 to push the cylindrical blank 7 into the mold cylinder 42 in the feed trough 411 area.

[0036] The working principle and usage process of this utility model are as follows: First, the heating temperature of the mold cylinder 42 in the feeding tank 411 and the forming tank 412, as well as the cooling temperature of the finished product in the discharge tank 61 after discharge, are set by the temperature controller 51. The forming temperature is lower than the feeding temperature. The infrared temperature sensor 54 above monitors the temperature in real time. Then, the temperature controller 51 is turned on to preheat the mold cylinder 42. The temperature controller 51 turns on the heating circuit of the heater 52. The heater 52 powers the electromagnetic coil 53 to generate an electromagnetic field around the mold cylinder 42, and the mold cylinder 42 is heated by electromagnetic induction.

[0037] The cylindrical blank 7 is then placed on the arc plate 34, and the hydraulic cylinder 31 is activated. The hydraulic cylinder 31 drives the extrusion column 33 through the hydraulic column 32 to push the cylindrical blank 7 into the mold cylinder 42 in the feeding trough 411 area to heat the cylindrical blank 7. At this time, due to the heat conduction of the mold cylinder 42 to the cylindrical blank 7 and the heat dissipation of the mold cylinder 42 to the surroundings, the heating temperature of the mold cylinder 42 fluctuates. The infrared temperature sensor 54 feeds back the temperature change to the temperature controller 51 in real time. When the actual temperature is lower than the set value, the temperature controller 51 increases the heating temperature of the heater 52 to make the actual temperature rise rapidly. When the actual temperature is higher than the set value, the temperature controller 51 disconnects the heating of the heater 52, starts the water pump 64 and opens the solenoid valve 66 to draw cold water from the cold water pool 65 and introduce it into the cooling pipe 55 through the water guide pipe 56, which circulates rapidly outside the mold cylinder 42 to cool the mold cylinder 42 and achieve high-precision control of the heating temperature of the mold cylinder 42.

[0038] After the temperature of the mold cylinder 42 stabilizes, the hydraulic cylinder 31 is started to drive the extrusion column 33 to push the heated cylindrical blank 7 into the mold cylinder 42 in the forming tank 412 area to start the forming extrusion operation. Since the aluminum material is at a high temperature and has strong fluidity, it quickly deforms and fills the cavity of the mold cylinder 42 under the extrusion action. However, the temperature at this time is higher than the forming temperature. The aluminum profile has too strong fluidity, and direct extrusion will cause the profile to deform and the dimensional accuracy to decrease. The temperature of the mold cylinder 42 in the forming area is adjusted by the feedback of the infrared temperature sensor 54 until the temperature drops to the set temperature. Then, the forming part is extruded with the shaping mold 43.

[0039] The molded part extends into the molding tank 412 and continues to advance below the spray plate 62. The water pump 64 is started to draw cold water from the cold water tank 65 and introduce it into the main pipe 64, which is then sprayed out by the spray plate 62 to continuously cool the molded part. The infrared temperature sensor 54 feeds back the cooling temperature of the molded part to the temperature controller 51. The temperature controller 51 controls the flow rate of cold water to the molded part by controlling the opening of the solenoid valve 66, thereby controlling the cooling temperature of the molded part. This enables differentiated temperature adjustment for different functional areas of the mold, adapting to the process requirements of different stages in the aluminum profile extrusion process, reducing extrusion resistance fluctuations and product defects caused by uneven temperature, and enhancing the stability of the extrusion process.
