[0022] The first vent 106 and the second vent 402 can prevent negative pressure from being generated inside the device, which would affect the preheating effect. A control system 105 is fixedly installed at the top center of the preheating box 101 to control the operation of the entire preheating mechanism.

[0023] like Figure 3As shown, the mold fixing assembly 2 includes a fixing frame 201 and two adjusting disks 202, the opposite sides of the two adjusting disks 202 are fixedly connected with adjusting handles 203, the opposite side walls of the two adjusting disks 202 are fixedly connected with double-headed screws 204 that penetrate into the fixing frame 201, the left and right outer walls of the two double-headed screws 204 are threadedly connected with threaded sleeves 205, the top of the threaded sleeve 205 is fixedly connected with a clamping plate 206, the outer wall of the threaded sleeve 205 is slidably connected with a groove 207 opened on the top of the fixing frame 201, the front and rear inner walls of the groove 207 are fixedly connected with a partition 208, the left and right sides of the partition 208 are rotatably connected to the left and right double-headed screws 204 respectively, and the left and right sides of the top of the fixing frame 201 are fixedly connected with connecting plates 200.

[0024] When in use, first open the sealing door 103, place the aluminum alloy casting mold in the fixed frame 201, and rotate the adjusting handle 203 to drive the adjusting disk 202 to rotate, thereby rotating the double-headed screw 204. The rotation of the double-headed screw 204 causes the threaded sleeve 205 to slide in the groove 207, thereby driving the clamping plate 206 to move, thereby clamping and fixing the mold. At the same time, the two double-headed screws 204 are rotatably connected to the partition 208. The two double-headed screws 204 can individually adjust the clamping plates 206 connected to their respective threads, so as to clamp and fix molds of different sizes, thereby increasing the adaptability of the device.

[0025] like Figure 4 As shown, the rotating assembly 3 includes a motor 1 301, the left side of the motor 1 301 is fixedly connected to the right side wall of the preheating box 101, the output end of the motor 1 301 is fixedly connected to a bevel gear 1 302, the left side of the bevel gear 1 302 is meshedly connected to a bevel gear 2 303, the left side of the bevel gear 2 303 is fixedly connected to a rotating rod 307 that penetrates the right inner wall of the preheating box 101, the left side of the rotating rod 307 is fixedly connected to a rotating disk 1 304, the left side of the rotating disk 1 304 is fixedly connected to a plurality of fixed cross bars 305 in an annular array, the left and right outer walls of the fixed cross bar 305 are rotatably connected to the left and right connecting plates 200 respectively, and the left end of the fixed cross bar 305 is fixedly connected to a rotating disk 2 306 rotatably connected to the left inner wall of the preheating box 101.

[0026] When it is necessary to rotate the fixed frame 201 so that the mold is heated evenly, the motor 301 is started through the control system 105. When the motor 301 is working, its output end drives the bevel gear 1 302 fixedly connected thereto to rotate, and the bevel gear 1 302 is meshed with the bevel gear 2 303 for transmission, so that the rotating rod 307 rotates, and then drives the rotating disk 1 304 and the fixed cross bar 305 to rotate. Since the fixed cross bar 305 is rotatably connected to the connecting plate 200, when the fixed cross bar 305 rotates, it drives the mold fixed on the fixed frame 201 to rotate, so as to achieve uniform preheating of all surfaces of the mold, thereby reducing the overall preheating time and improving production efficiency.

[0027] like Figure 4 , Figure 5 As shown, the preheating blowing assembly 4 includes a bellows 401, the bottom of which is fixedly connected to the top of the fixed plate 107, a second vent 402 is provided on the rear side wall of the bellows 401, a motor 2 403 is fixedly connected to the top of the bellows 401, a gear 1 404 is fixedly connected to the output end of the motor 2 403, a gear 2 405 is meshedly connected to the bottom of the gear 1 404, a blower 407 is fixedly connected to the front inner wall of the bellows 401, an air outlet pipe 411 is provided on the front side wall of the bellows 401, an air outlet pipe 411 is rotatably connected to the inner wall of the air outlet pipe 411, and an air guide pipe 408 is fixedly connected to the outer wall of the air guide pipe 408 and the inner wall of the gear 2 405 is fixedly connected.

[0028] like Figure 4 , Figure 5 As shown, one end of the air duct 408 away from the air outlet duct 411 passes through the rear inner wall of the preheating box 101 and is fixedly connected to a cross air duct 409, a front side wall of the cross air duct 409 is fixedly connected to a plurality of equally spaced air nozzles 410, and the upper and lower inner walls of the air box 401 are fixedly connected to a plurality of equally spaced heating wires 406, and the control system 105 is electrically connected to the motor 1 301, the motor 2 403, the heating wire 406 and the blower 407 respectively.

[0029] When the mold needs to be preheated by air blowing, the motor 2 403, the heating wire 406 and the blower 407 are turned on through the control system 105, the motor 2 403 drives the gear 1 404 to rotate, and the gear 1 404 drives the gear 2 405 to rotate, so that the air duct 408 rotates, and the wind is heated by the heating wire 406, and then blown evenly to the mold in the preheating box 101 through the cross air duct 409 and the air nozzle 410, so as to be adjusted according to different mold shapes and sizes. For molds with complex shapes, the rotating nozzle can flexibly adapt to their surface characteristics to achieve comprehensive preheating.

[0030] The working principle of the preheating mechanism for aluminum alloy casting mold is described in detail below.

[0031] like Figure 1-5As shown, when in use, first open the sealing door 103, place the aluminum alloy casting mold in the fixed frame 201, and rotate the adjusting handle 203 to drive the adjusting disk 202 to rotate, thereby rotating the double-headed screw 204. The rotation of the double-headed screw 204 causes the threaded sleeve 205 to slide in the groove 207, thereby driving the clamping plate 206 to move, thereby clamping and fixing the mold. At the same time, the two double-headed screws 204 are rotatably connected to the partition 208. The two double-headed screws 204 can adjust the clamping plate 206 separately, so that molds of different sizes can be clamped and fixed, thereby increasing the adaptability of the device.

[0032] When it is necessary to rotate the fixed frame 201 so that the mold is heated evenly, the motor 301 is started through the control system 105. When the motor 301 is working, its output end drives the bevel gear 1 302 fixedly connected thereto to rotate, and the bevel gear 1 302 is meshed with the bevel gear 2 303 for transmission, so that the rotating rod 307 rotates, and then drives the rotating disk 1 304 and the fixed cross bar 305 to rotate. Since the fixed cross bar 305 is rotatably connected to the connecting plate 200, when the fixed cross bar 305 rotates, it drives the mold fixed on the fixed frame 201 to rotate, so as to achieve uniform preheating of all surfaces of the mold, thereby reducing the overall preheating time and improving production efficiency.

[0033] When the mold needs to be preheated by air blowing, the motor 2 403, the heating wire 406 and the blower 407 are turned on through the control system 105, the motor 2 403 drives the gear 1 404 to rotate, and the gear 1 404 drives the gear 2 405 to rotate, so that the air duct 408 rotates, and the wind is heated by the heating wire 406, and then blown evenly to the mold in the preheating box 101 through the cross air duct 409 and the air nozzle 410, so as to be adjusted according to different mold shapes and sizes. For molds with complex shapes, the rotating nozzle can flexibly adapt to their surface characteristics to achieve comprehensive preheating.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
