The invention discloses hot bending forming equipment which comprises a heating device used for keeping a product at a preset forming temperature and a lower die located below the heating device, wherein a forming groove is formed in the top of the lower die; the lower die is a heat insulation die, so that the temperature of the lower die is lower than the preset forming temperature of the product in the forming process; the lower die is provided with a lower die air outlet channel used for being connected with a negative pressure device, and an air inlet of the lower die air outlet channel extends to the forming groove; and / or the hot bending forming equipment further comprises an upper die located on the lower die, wherein the upper die is provided with an upper die air outlet channel used for being connected with a positive pressure device, and an air outlet of the upper die air outlet channel faces the forming groove. According to the hot bending forming equipment, air blowing and / or air suction are / is conducted on the product at the preset forming temperature, the upper surface of the product does not make contact with the upper die, the lower surface of the product makes contact with the low-temperature lower die, and die indentations and concave-convex points on the surface of the product are reduced.
Description
Technical field [0001] The present application relates to the technical field of glass styling equipment, and more particularly to a hot bending device. Background technique [0002] At present, in the process of thermally benting the glass, it is necessary to place the glass in the cavity of the mold. Since the graphite material is stable, the coefficient of expansion is small, so the mold is generally made of graphite material, and the mold is heated by the heating device, and the heat is conducted through the mold to the product, and the product is deformed in high temperature, and finally with the mold cavity The shape is maintained. [0003] However, in the actual processing, the glass surface will be squeezed by the mold, and there is a problem such as a multi-mold indentation, unevenness, affecting the product quality, and then requires polishing processes to remove the product surface. [0004] In summary, how to provide a thermal bending device, which is used for the sur...
