Embodiment 3
[0073] Embodiment 3: Apply the demoulding machine in the embodiment 1 to carry out the demoulding experiment to the rutting plate trial mold prepared in the embodiment 2
[0074] 1, the stripping machine in the application embodiment one carries out the stripping process as follows:
[0075] (1) Push the trial mold 2 of the formed rut plate into the trial mold frame 101, and the direction with the clamping plate 202 is the front and rear direction, so that the clamping plate 202 is stuck on the frame of the trial mold frame 101, and the trial mold 2 is carried out Fixed place, and then wait for demoulding;
[0076] (2) Press the power and down buttons. At this time, under the action of the motor 7, the elevating rod 401 rotates, and the elevating rod 401 drives the force application table 5 to descend simultaneously. The force application column 501 and the magnetic disk 502 resist the force application through the force application hole 201 Plate 203, as the force-applying p...
