Fig. 4 is the structural representation of above-mentioned guider ring.Please consult Fig. 3 and shown in Figure 4 simultaneously, in the present embodiment, the material of this guider ring 240 can be metallic substance or alloy material, alloy material can be stainless steel, for example SUS316 or SUS310, and guider ring 240 is high thermal expansion coefficient person, and its thermal expansivity is usually greater than optical mirror slip, mold 220 thermal expansivity with bed die 230.Wherein, the internal diameter of guider ring 240 is usually greater than the external diameter of optical mirror slip (not illustrating), is adhered on the guider ring 240 to avoid the optical mirror slip after the moulding.And the external diameter of guider ring 240 less than the internal diameter of cylindrical mould 210, produces the situation of distortion usually to avoid guider ring 240 to be expressed to cartridge type mould 210 when high temperature expands.In addition, guider ring 240 more is provided with four ease channelings 242 away from the end face 244 of bed die 230, discharges in order to the entrap bubble in the die cavity 250.Yet the number of ease channeling 242 is not limited only to four in the present embodiment, and it also can be set to greater or less than four.
Please consulting simultaneously shown in Fig. 5 A to Fig. 5 C, is each step synoptic diagram that above-mentioned modeling device for optical lens is used in mould model.At first, shown in Fig. 5 A that 210 groups of bed die 230 and cylindrical moulds is upright, and dispose the planar portions 232 of a guider ring 240 in bed die 230.Then, a glass nitre material 50 is placed on the central position of compacted under portion 231, and mold 220 is upright with bed die 230 and 210 groups of cylindrical moulds, and then form a die cavity 250.Wherein, must there be the formed gap 260 of a machining tolerance between mold 220 and bed die 230 and the cylindrical mould 210, the width of this tolerance clearance 260 is about 5～20 microns so that mold 220 and bed die 230 easily and 210 groups of cylindrical moulds upright.At this moment, this gap 260 may cause mold 220 organizing the tilt phenomenon that occurrence degree immediately differs, and make between the central shaft C2 of the central shaft C1 of mold 220 and bed die 230 and produce an angle theta, yet this problem can solve at next step.
Then, shown in Fig. 5 B, along with mold 220 pressing downwards gradually, glass nitre material 50 also begins compressive deformation.And, because the relation that mold 220 tilts makes that the glass nitre material 50 in the moulding also produces the situation of inclination with the contact surface 52 of mold 220.But, when the planar portions lower-most point 222a of mold 220 touches guider ring 240, can be subjected to stopping of guider ring 240 and stop downward pressing.At this moment, the higher-end 222b that planar portions 222 does not contact with guider ring 240 as yet can continue to be under pressure and pressing downwards, and is smooth on guider ring 240 until whole planar portions 222.
