[0030] When the above device is actually used, the workpiece is placed in the shaping unit, and the workpiece is subjected to high temperature pressure shaping by operating the button 6. The upper drive motor 3 and the lower drive motor 4 drive the workpiece to undergo high temperature pressure shaping.

[0031] Combination Figure 4 , Figure 5 and Figure 6The shaping unit includes a middle mold template 12, which is connected to the mold frame 5. The upper end of the middle mold template 12 is provided with a plurality of symmetrically arranged upper guide pillars 13, and the outer side of the upper guide pillar 13 is sleeved with an upper punch template 14. The upper punch template 14 is connected to the output end of the upper drive motor 3 through a ball screw. The side of the upper guide pillar 13 is fixedly connected with a guide sleeve 15. The lower end of the middle mold template 12 is provided with a plurality of symmetrically arranged guide shafts 16, and the outer side of the guide shaft 16 is sleeved with a lower pull-down plate 17. The lower pull-down plate 17 is connected to the output end of the lower drive motor 4 through a ball screw. The screw rod is connected, and a heating rod seat 18 is arranged on the pull-down plate 17. A fixing plate 19 is sleeved on the outer side of the heating rod seat 18. The fixing plate 19 is sleeved on the outer side of the guide shaft 16. The fixing plate 19 is used to limit the heating rod seat 18. A heating rod body 20 is arranged on the upper end of the heating rod seat 18. The side surface of the heating rod body 20 and the lower end of the upper punch template 14 are cooperated with a heating body 21 for heating the workpiece. The heating body 21 is electrically connected to the control button 6 through a thermocouple 22. The thermocouple 22 is used to adjust the temperature of the heating body 21.

[0032] The mold frame 5 is provided with a pressure sensor 23 , and the pressure sensor 23 is electrically connected to the display screen 7 . The pressure sensor 23 monitors the pressure exerted on the workpiece on the middle mold plate 12 .

[0033] A heat preservation plate 24 is disposed at the lower end of the upper punch plate 14 , and the heat preservation plate 24 is electrically connected to the heating body 21 .

[0034] The middle mold template 12 is provided with a positioning pin 25 , and the positioning pin 25 is used for quickly changing the mold of the middle mold template 12 .

[0035] The outer side of the guide shaft 16 is sleeved with a graphite bushing 28 for blocking the heat generated by the heating body 21 . The fixing plate 19 and the upper punch template 14 are provided with a water circulation system 29 for blocking the heat from being transferred to the mold frame 5 .

[0036] When the above-mentioned shaping unit is actually used, the ball screw of the lower driving motor 4 and the upper driving motor 3 converts the rotational motion into a linear motion, thereby driving the upper punch template 14 and the lower pull plate 17 to reciprocate, and the lower pull plate 17 is connected to the middle mold template 12 through the guide shaft 16 to drive the middle mold template to move the upper punch template 14, the insulation plate 24, the middle mold template 12, the fixed plate 19, and the mold installation area are all heated by the heating rod body 20, and the thermocouple 22 detects the temperature to achieve temperature control. The connection between each template and the mold is treated with a heat insulation plate 27 to isolate the temperature, and each template is designed with a water circulation cooling system to further block the heat transfer. By forming the end face area of ​​the upper punch The design of adding the insulation plate 24 allows the upper punch to be heated evenly, avoids deformation due to heat, and increases the service life of the upper punch. The insulation plate 24 and the upper punch template 14 adopt the design of an upper guide column 13 plus a mold spring 26. The upper guide column 13 plays a guiding and limiting function. The mold spring 26 provides power so that when the upper punch is pressed down into the cavity of the middle mold template 12 for molding, the insulation plate 24 is blocked by the middle mold template, the mold spring 26 is compressed, and the upper punch template 14 leaks out of the insulation plate 24 and enters the cavity of the middle mold template 12. After molding is completed, the upper punch template 14 separates from the middle mold template 12 and rises, and the mold spring 26 releases the pressure and returns to its original position, so that the upper punch is in the cavity of the insulation plate 24 to maintain the temperature.

[0037] While ensuring accuracy, the temperature during pressing is kept above 400°C. In order to maintain the temperature while taking into account the accuracy of the machine, the equipment uses an integrally formed casting as the main frame to improve rigidity. The heating part uses multiple heating rods 20 to provide heat and multiple thermocouples 22 to detect heat to ensure that each area is controllable and the heating body 21 is evenly heated. The mold frame 5 body is made of special heat-resistant mold steel to reduce thermal deformation. The grease in the guide lubrication part will evaporate and become ineffective due to heat. Therefore, a graphite bushing 28 with a no-oiling function is used, and the shaft is treated with a ceramic coating process to increase wear resistance and reduce the impact of thermal deformation. The mold connection part of the mold frame 5 uses insulation materials to isolate and ensure the heat of the mold part while reducing the heat transfer to the mold frame 5. A water circulation cooling system is also made between the layers of the mold frame 5 to further reduce the heat transfer to the mold frame 5 and reduce the accuracy.
