The extrusion die box 5 has at least two types: a flat die box 51 and a special-shaped die box 52. The extrusion template 4 and the extrusion die box 5 can be replaced at will according to the required shape, which is very convenient.

[0026] Combine Figure 4 and Figure 5 The lower surface of the extrusion template 4 and the upper surface of the extrusion die box 5 are both connected to a resistor plate 44. The exposed bottom surface of the resistor plate 44 is coated with a material with a large reflection coefficient for heating the PEEK sheet prepreg by infrared radiation while extruding it to cause it to deform rapidly.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] Working principle: Place the PEEK sheet prepreg on the hollow mold box 8, insert the hollow mold box 8 into the third card slot 14, insert the electric heating radiation plate 6 into the second card slot 13 and the fourth card slot 15 respectively, turn on the power, the electric heating radiation plate 6 generates heat to dry and preheat both sides of the PEEK sheet prepreg, then take out the PEEK sheet prepreg and place it in a suitable extrusion mold box 5, insert the extrusion mold box 5 into the first card slot 12 or the third card slot 14 or the fifth card slot 16, select the matching extrusion mold box. Press the die plate 4, connect the extrusion die plate 4 to the telescopic rod 3, and then sleeve the telescopic rod 3 onto the slide bar 2.
