After the knocking is completed, the spring 704 resets the knocking rod 702, so as to knock repeatedly, so that the pressed product in the lower mold 2 vibrates, and the knocking action of the knocking assembly 7 causes the pressed product in the lower mold 2 to vibrate, and this vibration helps to break the adhesion between the product and the mold, so as to facilitate demoulding.
