    • PROBLEM TO BE SOLVED: To take out a formed article in a hot environment while preventing die oxidation.
      SOLUTION: A heating unit 13 is disposed so as to freely move between a heating position for heating around a pair of dies 11, 12 and a non-heating position left upward. The heating unit 13 is cylindrical and shields the pair of dies 11, 12 and a space around these when it is in the heating position. A cylindrical partition member 14 is attached to the lower side of the heating unit 13. The partition member 14 shields the pair of dies 11, 12 and a space around these when the heating unit 13 is in the non-heating position. When a formed article is taken out, an inert gas is fed into the space shielded by the partition member 14, and while keeping the space under high pressure, the formed article is taken out from a mouth 14a disposed in the partition member 14.

    • 要解决的问题:在热环境中取出成型制品,同时防止模具氧化。 解决方案:加热单元13设置成在一对模具11,12之间加热的加热位置和向上的非加热位置之间自由移动。 加热单元13是圆柱形的,并且在它们处于加热位置时屏蔽一对模具11,12和围绕它们的空间。 圆筒形分隔构件14附接到加热单元13的下侧。当加热单元13处于非加热位置时,分隔构件14屏蔽一对模具11,12和围绕这些的间隔。 当取出成形物品时,将惰性气体供给到被分隔构件14遮蔽的空间内,同时在保持高压空间的同时,将成形物从设置在分隔构件14上的口部14a取出。 P>版权所有(C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a glass forming apparatus in which the pressing force of a die is precisely controlled and the precise glass forming is carried out.
      SOLUTION: Control valves 31 and 32 for supplying an inert gas into a forming chamber 17 from gas supply passages 23, 24 and 25 carry out the supply and stoppage of the inert gas based on the direction given by a control apparatus 28 and gradually increase or decrease the pressure and the flow rate of the inert gas to be supplied up to a prescribed value. As a result, the radical pressure change (vibration) in the forming chamber 17 and the output change of the output (vibration) of a load detector 8b which occur with the supply and the stoppage or the change of the flow rate of the inert gas are suppressed to precisely control the pressing force.
