PURPOSE:To contrive energy saving by heating a mold by uniformly, by controlling a flowing direction of hot air blowing against the mold body by a fin held on to a frame body. CONSTITUTION:The titled molding tool is so constituted that it is composed of a mold body 2 held on to the lower end surface of a frame body 1 and a fin 3 held on to the frame body 1 at an adjustable angle the mold body 2 is provided in such a manner that a mold surface 21 is faced outward of the frame body 1 and the back 22 is faced inward of the frame body 1 an hot air is blown against the back side of the mold body 2. The fin 3 hinged to the frame body 1 an angle of which is controlled so that the hot air abutted against the fin 3 is sent to a hollow part 23 of the back 22 of the mold body 2. Therefore, it is possible to send the hot air to the hollow part 23 which serves as a dead angle of a hot air passage by the fin 3, the whole of the mold body 2 is heated at about a uniform heating rate and waste of energy required for heating is saved. |
