Abstract
PURPOSE:To largely shorten molding cycle time, by cooling the metallic mold with cooling water immediately after vacuum molding and, at the same time, by cooling the mold goods adsorbed on the surface of metallic mold by directly injecting cooling wind. CONSTITUTION:After fixing thermoplastic resin sheet 9 on the upper surface of outer circumference of metallic mold by using junk frame 8 so that they are airtightly contacted, the sheet 9 is softened. Next, the vacuum pump is operated to exhaust the air in an empty part, formed between the sheet 9 and surface of the metallic mold 1, through an exhaust hole 5. Then, the sheet 9 is adsorbed on the surface of metallic mold 1 to mold them in the form of diaphragm. While, the metallic mold 1 is cooled by flowing cooling water in cooling water path 7, and at the same time, the injection part of cooling wind 10 is moved on the upper part of the metallic mold. Directly cooling wind from cooling blower is injected to mold goods 9a in a form of a diaphragm which is adsorbed on the surface of the metallic mold to cool the mold goods 9a. Compressed air is blown to the modl goods 9a through an exhaust hole and peels off the mold goods 9a from the surface of the metallic mold 1.
