Abstract:
1. A mold comprising: a first mold half comprising a first mold base and a first mold core connected to the first mold base, the first mold core comprising a first molding face, the first mold core further comprising four side faces extending from the first mold base to the first molding face and perpendicular to the first molding face and the first mold base, the four side face being respectively a first side face, a second side face, a third side face, and a fourth side face; a second mold half opposite to the first molding face of the first mold half; and a first thermoelectric generator comprising: a second thermoelectric generator positioned in contact with the second mold half, wherein the second mold half comprises a second mold base and a second mold core connected to the second mold base, the second mold core comprises a second molding face corresponding to and facing the first molding face, the second mold core further comprises four side surfaces extending from the second mold base to the second molding face and perpendicular to the second molding face and the second mold base, the four side surface is respectively a first side surface, a second side surface, a third side surface, and a fourth side surface, the second thermoelectric generator comprises a second high temperature conductive portion, a second semiconductor electricity-generating portion, and a second low temperature conductive portion exposed to the air; the second high temperature conductive portion defines a receiving space having a shape substantially identical to that of the second mold core, the first high temperature conductive portion is configured to enclose and contact the four side surfaces of the second mold core and configured to conduct the heat emitted from the second mold half to the second semiconductor electricity-generating portion when the second mold core mates with the receiving space; the second semiconductor electricity-generating portion is sandwiched between the second high temperature conductive portion and the second low temperature conductive portion, and positioned in contact with the second high temperature conductive portion and the second low temperature conductive portion; the second semiconductor electricity-generating portion is configured for forming a voltage difference according to a temperature difference between the second high temperature conductive portion and the second low temperature conductive portion.
