When die unit 8 is transported in the 2nd heating chamber 22, carry out the 2nd heating steps forming mould 52 of die unit 8 being heated to glass sag temperature level.In the 2nd heating chamber 22, guarantee identical with glass sag temperature or more temperature by well heater 34.Thus, the glass material 60 be transported in the die unit 8 in the 2nd heating chamber 22 is arrived glass sag temperature level by heating.
Through the productive temp time preset when the rotation of the universal stage 4 from last time, the gate be arranged between the circumferential direction end of inner shell 6 and each room is opened, and universal stage 4 is rotated counterclockwise 45 degree in plan view.Thus, die unit 8 is transported in equal hot cell 24.
When forming mould 52 is transported in equal hot cell 24, carry out the soak step of glass material 60 evenly heating making forming mould 52 and inner collecting.In equal hot cell 24, guarantee glass sag temperature level by well heater 36.Thus, the forming mould 52 in equal hot cell 24 is transported to and the glass material 60 in forming mould 52 carries out evenly heating with glass sag temperature.
Through the productive temp time preset when the rotation of the universal stage 4 from last time, the gate be arranged between the circumferential direction end of inner shell 6 and each room is opened, and universal stage 4 is rotated counterclockwise 45 degree in plan view.Thus, die unit 8 is transported in mold pressing room 26.
When die unit 8 is transported in mold pressing room 26, carry out molding process.In molding process, undertaken heating to make die unit 8 guarantee glass sag temperature level by well heater 38, and, pressed multiple forming moulds 52 of die unit 8 by molding mechanism 70 simultaneously, compression molding is carried out to glass material.Below, the mold pressing process by this molding mechanism 70, multiple forming mould 52 being carried out to mold pressing is described in detail.
As shown in Figure 6, when mold pressing process starts, the piston rod 82 of actuator 80 is in the state of retrogressing.Under this state, the length that whisker 106 becomes natural length(of wool) or compresses a little than natural length(of wool).Further, by making the nut 104 on the top being arranged on axle 100 engage with the upper surface of movable plate 86, under a mold pressing state that there is gap between 102 and forming mould 52, each axle 100 is kept.
When starting to carry out mold pressing process, first, actuator 80 makes piston rod 82 decline downward.As mentioned above, movable plate 86 keeps level by guide 81, and can move in the vertical direction.Therefore, actuator 80 makes piston rod 82 decline, thus, and movable plate 86 maintenance level and moving downward.
When movable plate 86 moves downward, the lower surface of movable plate 86 abuts with the top of whisker 106 or compresses whisker 106.Further, the below of whisker 106 abuts with the sticking department 101 of axle 100.Therefore, when movable plate 86 declines, axle 100 carries out downward pressing across whisker 106 mobile.Thus, the mold pressing 102 being arranged on the lower end of axle 100 abuts with the upper surface of forming mould 52.Now, by being arranged on the straight line sleeve 114 on framework lid material 110, the forming mould 52 towards correspondence reliably guides each axle 100.
After mold pressing 102 abuts with the upper surface of forming mould 52, before whisker 106 is retracted to specified length, actuator 80 makes piston rod 82 extend downward.Like this, by the contraction of whisker 106, pressing load is applied to each forming mould 52.In addition, to make the mode that the recuperability of whisker 106 is equal with the molding pressure load that will be applied to forming mould 52, determine the length of the contraction schedule of whisker 106.In addition, according to the material etc. of glass material, in the scope of 10 ~ 500kgf, set this molding pressure load (thrust).
Then, keep the specified time under the state making whisker 106 shrink like this (such as tens of second ~ several minutes).Thus, transfer printing molded shape on the glass material of collecting in forming mould 52 can compression molding be the glass forming body (optical element) of intended shape.
Now, there is deviation in the height of the support 12B of mould supporting station 12, and the height of the upper surface of multiple forming mould 52 exists error sometimes.Like this, even if the height of the upper surface of multiple forming mould 52 exists error, whisker 106 also absorbs the error of this upper level, so, whole forming mould 52 can be pressed.But, like this, although the error of the height of the upper surface of forming mould 52 can be absorbed by whisker 106, due to the error of this upper level, the length of the contraction schedule of whisker 106 produces difference.Like this, when the length of the contraction schedule of whisker 106 there are differences, the molding pressure load for forming mould 52 also produces difference.
On the other hand, in the present embodiment, because whisker 106 is arranged on the outside of framework 2, so, as whisker 106, the whisker that total length is longer can be used.Like this, by using the longer whisker of total length as whisker 106, the difference in height of forming mould 52 reduces relative to the ratio of the length under the contraction schedule of whisker 106.Thereby, it is possible to suppress smaller to become to the difference of the molding pressure load that each forming mould 52 applies the degree not having materially affect.
Then, after mold pressing process terminates, actuator 80 makes piston rod 82 retreat.By making piston rod 82 retreat, movable plate 86 rises.Thus, whisker 106 is elongated to natural length(of wool) again, is removed the molding pressure load that forming mould 52 applies.And then actuator 80 makes piston rod 82 retreat, make movable plate 86 increase, thus, the nut 104 being arranged on the top of axle 100 abuts with the upper surface of movable plate 86, makes axle 100 increase.Thus, mold pressing 102 and forming mould 52 leave.By above operation, mold pressing process completes.
Then, molding process completes, and through the productive temp time when the rotation of the universal stage 4 from last time, the gate be arranged between the circumferential direction end of inner shell 6 and each room is opened, and universal stage 4 is rotated counterclockwise 45 degree in plan view.Thus, the forming mould 52 of die unit 8 is transported in the 1st slow cooling room 28.
In the 1st slow cooling room 28, carry out being adjusted to the temperature of mould 52 and the 1st slow cooling step of Slow cooling forming mould 52 by well heater 40.In the scope of 10 ~ 100 DEG C/minute, preferably suitably set speed of cooling now.
Then, the 1st slow cooling step completes, when from the rotation of last time through the productive temp time preset, the gate be arranged between the circumferential direction end of inner shell 6 and each room is opened, and universal stage 4 is rotated counterclockwise 45 degree in plan view.Thus, the forming mould 52 of die unit 8 is transported in the 2nd slow cooling room 30.
In the 2nd slow cooling room 30, carry out being adjusted to the temperature of mould 52 and the 2nd slow cooling step of Slow cooling forming mould 52 by well heater 42.In the scope of 10 ~ 100 DEG C/minute, preferably suitably set speed of cooling now.
Through the productive temp time when the rotation of the universal stage 4 from last time, the gate be arranged between the circumferential direction end of inner shell 6 and each room is opened, and universal stage 4 is rotated counterclockwise 45 degree in plan view.Thus, the forming mould 52 of die unit 8 is transported to chilling portion 44 from the 2nd slow cooling room 30.
When forming mould 52 is transported in chilling portion 44, carry out quench step.In chilling portion 44, well heater is not set, become with device around the temperature of same degree.Therefore, the glass forming body of the inside of die unit 8 and forming mould 52 is cooled rapidly.Preferred speed of cooling is now faster than the speed of cooling in slow cooling step, such as, suitably set in the scope of 30 ~ 300 DEG C/minute.Further, also cooling gas can be blown out towards die unit 8 as required.
And then through the productive temp time preset when the rotation of the universal stage 4 from last time, universal stage 4 rotates 45 degree, and die unit 8 is shifted into move-in/move-out portion 46.When the die unit 8 of the glass forming body after containing forming processes and completing arrives move-in/move-out portion 46, make die unit 8 increase by hoisting appliance, from move-in/move-out mouth to the outside of device framework 2 take out of simultaneously multiple forming processes complete after forming mould 52.
