[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figure 1-5As shown, this utility model provides an automated temperature control and stress monitoring device for H13 steel extrusion cake, including a mold body 1, an inner module 2 installed inside the mold body 1, strain gauges 3 installed on the inner wall of the inner module 2, a heating wire 5 located outside the inner module 2 inside the mold body 1, a condenser tube 6 located above the heating wire 5 inside the mold body 1, a first partition plate 15 fixed to the bottom end of the mold body 1, a fixing block 16 fixed to the bottom end of the first partition plate 15, clamping plates 18 on both sides of the bottom end of the fixing block 16, a clamping plate 19 fixed to the opposite end of the two clamping plates 18, a driving structure 20 for driving the two clamping plates 18 to move in opposite directions or opposite directions inside the fixing block 16, and a stress monitoring module 24 and a temperature monitoring module 25 installed on the outer side of the mold body 1.

[0026] The overall effect of Embodiment 1 is that, through the setting of strain gauge 3 and stress monitoring module 24, when the extrusion cake is subjected to thermal stress, mechanical stress and shear stress, strain gauge 3 will produce corresponding physical changes as the extrusion cake deforms. The strain gauge 3 reflects the strain magnitude through the change of resistance value, and is transmitted to stress monitoring module 24 via data transmission line. Stress monitoring module 24 analyzes and processes the signal to calculate the stress magnitude, direction and distribution of each part of the extrusion cake. Through the setting of temperature monitoring module 25, the temperature inside the mold body 1 can be monitored, and the heating wire 5 can be controlled. The operation of the condenser 6 achieves the effect of regulating the temperature inside the mold body 1, making it more practical. Through the operation of the drive structure 20, the two clamping plates 18 can be driven to move in opposite directions. It is only necessary to open the corresponding slots of the clamping plates 18 and the clamping plates 19 on the worktable in advance. When the two clamping plates 18 move in opposite directions, they will drive the two clamping plates 19 to engage in the slots opened at the top of the worktable, thereby achieving the effect of clamping and holding the mold body 1. When disassembling, it is only necessary to move the two clamping plates 18 in opposite directions. Compared with the traditional screw installation and disassembly, this installation and disassembly method is faster and more practical.

[0027] Example 2, as Figure 1-5As shown, the drive structure 20 includes a motor 2001 located at one end of the fixed block 16. The output end of the motor 2001 passes through one side of the fixed block 16 and is fixed with a bidirectional screw 2002. Both ends of the outer wall of the bidirectional screw 2002 are threadedly connected to movable plates 2003. The ends of the two movable plates 2003 away from the bidirectional screw 2002 are slidably connected to limit posts 2004. The bottom ends of the two movable plates 2003 are fixed with connecting plates 2005. The bottom of the two connecting plates 2005... Both ends of the heating wire 5 and the condenser tube 6 pass through the fixing block 16 and are respectively fixed to the two clamping plates 18. The mold body 1 has an inner cavity 4. Multiple support plates 7 are fixed on the inner wall of the inner cavity 4. The heating wire 5 and the condenser tube 6 are fixed to the inner wall of the inner cavity 4 through the support plates 7. Heat-conducting plates 8 are fixed on the outer walls of the heating wire 5 and the condenser tube 6. One end of the heat-conducting plate 8 passes through the mold body 1 and abuts against the inner module 2. Both ends of the condenser tube 6 pass through the mold body 1. Flanges 9 are fixed on the outer walls of both ends of the condenser tube 6. The bottom ends of the body 1, strain gauge 3 and inner module 2 are all provided with a first opening 10. The bottom end of the first opening 10 is equipped with a mounting plate 11 by bolts 14. The top end of the mounting plate 11 is located inside the first opening 10 and is equipped with an electric telescopic rod 12. The output end of the electric telescopic rod 12 is fixed with a ejector pin 13. The end of the bidirectional screw 2002 away from the motor 2001 is rotatably connected to the fixing block 16. Both ends of the limiting post 2004 are fixed to the fixing block 16. The bottom ends of the fixing block 16 are respectively provided with moving grooves 21 that match the two connecting plates 2005. One end of the fixing block 16 is fixed with a fixing frame 22. The motor 2001 is installed on the end of the fixing frame 22 facing the fixing block 16. The first partition plate 15 and the mold body 1 are both provided with a second opening 17 that matches the mounting plate 11. Two second partition plates 23 are fixed to the outer wall of one end of the mold body 1. The stress monitoring module 24 and the temperature monitoring module 25 are respectively fixed to the mold body 1 through the second partition plates 23.

[0028] The effect achieved by the entire embodiment 2 is that the operation of the motor 2001 drives the bidirectional screw 2002 to rotate, causing the two moving plates 2003 to move towards or in opposite directions under the limitation of the limiting post 2004. This, in turn, drives the two clamping plates 18 connected by the two connecting plates 2005 to move towards or in opposite directions. When installing or disassembling the mold body 1, it is only necessary to pre-open slots corresponding to the clamping plates 18 and the locking plates 19 on the worktable. When the two clamping plates 18 move towards each other, they will drive the two locking plates 19 to engage in the slots opened at the top of the worktable, thereby achieving the effect of clamping and holding the mold body 1. When disassembling, it is only necessary to move the two clamping plates 18 in opposite directions. Compared to traditional screw installation and removal, this installation and removal method is faster and more practical. The flange 9 facilitates the connection of both ends of the condenser pipe 6 to the external heat exchange device, making it easy to replenish condensate. The operation of the electric telescopic rod 12 can drive the ejector pin 13 to rise and fall, thereby ejecting the processed steel. The mounting plate 11 and bolts 14 facilitate the installation and removal of the entire electric telescopic rod 12. The first partition plate 15 and the second partition plate 23 can isolate the mold body 1 from the stress monitoring module 24, temperature monitoring module 25 and fixing block 16 respectively, preventing the temperature of the mold body 1 from affecting it and making it more stable.

[0029] Working Principle: When this device is in use, the strain gauge 3 and stress monitoring module 24 are configured. When the extruded cake is subjected to thermal stress, mechanical stress, and shear stress, the strain gauge 3 will undergo corresponding physical changes as the extruded cake deforms. The strain gauge 3 reflects the magnitude of the strain through changes in resistance value, which is transmitted to the stress monitoring module 24 via a data transmission line. The stress monitoring module 24 analyzes and processes the signal, calculating the magnitude, direction, and distribution of stress in various parts of the extruded cake. The temperature monitoring module 25 monitors the temperature inside the mold body 1. By controlling the operation of the heating wire 5 and the condenser 6, the temperature inside the mold body 1 can be regulated, enhancing its practicality. The operation of the motor 2001 drives the bidirectional screw 2002 to rotate, causing the two moving plates 2003 to move relative to the limiting post 2004. The two clamping plates 18 connected by the two connecting plates 2005 can move in opposite directions or to each other. When installing or disassembling the mold body 1, it is only necessary to open the corresponding slots of the clamping plates 18 and the clamping plates 19 on the worktable in advance. When the two clamping plates 18 move in opposite directions, they will drive the two clamping plates 19 to engage in the slots opened at the top of the worktable, thereby achieving the effect of clamping and holding the mold body 1. When disassembling, it is only necessary to move the two clamping plates 18 in opposite directions. Compared with the traditional screw installation and disassembly, this installation and disassembly method is faster and more practical. The flange 9 facilitates the connection of both ends of the condenser pipe 6 with the external heat exchange device, which is convenient for replenishing condensate. The operation of the electric telescopic rod 12 can drive the ejector pin 13 to rise and fall, thereby ejecting the processed steel.

Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring arrangements of the motor 2001, stress monitoring module 24, temperature monitoring module 25, heating wire 5, strain gauge 3, and condenser tube 6 will not be explained in detail.
