[0041] The heating element fixing heat conducting plate 63 is made of a plate having a heat conducting material such as copper, and conducts heat to the heating element and conducts it to the heat conducting nut removing press head 67 .

[0042] The heat-conducting nut-removing press head 67 adopts a hard press head made of heat-conducting materials such as copper, and adopts a column structure adapted to the nut model.

[0043] After pressing the start button on the control panel, the equipment starts to work. The controller controls the heating element 66 to heat, and uses the temperature sensing element 65 to monitor the temperature. After the temperature reaches the set value of 200°C, the operation starts.

[0044] Place the plastic injection molded product 74 with the nut to be removed on the product carrier 7. By pressing down the handle of the quick clamp 5, the punching mechanism 6 will also press down synchronously along the slide rail 3.

[0051] First, after pressing the start button, the machine controller controls the preheating. After about twenty minutes of preheating, the actual temperature of the preheating mechanism of the heating element 66 reaches the preheating temperature. After confirming that the actual temperature is normal, the personnel can operate this machine to perform the nut withdrawal operation.

[0052] Place the plastic injection molding product 74 that needs to have its nuts removed on the nut removal carrier. After confirming that the temperature is normal, press down the handle of the manual clamp 5. The punch mechanism 6 will also press down along the slide rail 3. After contacting the copper nut, the pressure rod will transfer its own temperature to the copper nut. Each nut position has a corresponding pressure rod. Preheat for about 5-10 seconds. After the copper nut melts the surrounding plastic, press the manual clamp 5 down again. The nuts on the plastic injection molding product will all be removed at once and returned to the nut collection box. Lift the handle of the manual clamp 5 upward, the preheating mechanism returns to the original position, remove the product with the nuts removed, and repeat this action in sequence.

[0053] Because there are flat embedded nuts and angled embedded nuts on the product, one machine has two nut removal mechanisms, such as Figure 1 As shown, the left one is for withdrawing the flat nut, and the right one is for withdrawing the angle nut. The operation method is the same.
