Field of the Invention The present invention relates to a forming apparatus, and more particularly to a fixed glass mold forming apparatus which can simplify a core take-up operation. [Prior Art] As shown in FIG. 2 and FIG. 2, a conventional type for forming an optical glass lens includes an upper mold unit 2, which can be separated from the lower mold unit 1 by an upper mold unit 2 . The lower die unit i has a lower mold base (8) and a lower mold core 1 () 2 installed in the lower mold base (8). The upper mold unit 2 also has an upper mold base 2〇1 and is mounted thereon. The upper mold in the mold base 2〇1 is moved. When the glass 3 is placed on the lower mold 1 () 2, the upper mold unit 2 can be moved down during the high temperature molding process and is brought into engagement with the lower mold sheet & i, and the glass is The nitrate material 3 is press-formed into a glass lens 4. In the imaginary line of Fig. 1 and the imaginary line shown in Fig. 3, the glass stone material 3 is placed in a private state, and the center position may deviate from the central axis position of the lower mold 卩iG2, when the upper and lower mold units are opposite. When the glass is in close contact, the glass bowl 3 will cause partial meat. Or because the upper and lower mold cores 2 () 2, (10) have a smooth surface, and the glass nitrate material 3 has an elliptical shape. When the upper and lower mold units 2 and 1 are relatively close to each other, the glass cross-section is easily displaced. Because of the partial meat, the glass sapphire 3 may also be formed into the eccentric lens 5 and become a defective product. ~4, 'Whether the glass lens 4 or the partial lens 5/moulding operator needs to manually rotate the core to take the mold ό, to be sandwiched between the core take-up molds 6 Between the glass lens 4 or the partial lens 5 spoons, the shovel is found (in the case of the glass lens 4 in Fig. 4), and then 252842 dan stalks a stone and an end face 402, so that The glass lens 4 becomes a finished lens 4' having a guest outer diameter D j and a sin surface 401. However, the outer peripheral surface 4 of the glass lens 4 is formed when the glass lens 4 or the partial lens 5 is formed. 〇1 (or the outer peripheral surface of the partial lens 5) is not restricted by a specific structure, and therefore, the glass lens 4 or the partial lens 5 does not have a completely uniform outer diameter configuration, and the operator performs the core. When taking the homework, it usually takes a considerable amount of time to find the core point, especially the partial lens 5 is more expensive; more time, because the outer diameter of the glass lens 4 or the partial lens 5 is not Both = /, and the operator is operating the core picking mold 6 by experience and feeling, which often causes the finding The actual optical axis of the finished lens 4 is deviated from the position of the finished lens 4, which causes a problem of poor core alignment. In addition, there is no outer peripheral surface of the deformed sheet 4 or the outer peripheral surface of the partial lens 5. Subject to: 4 or (4) (4) The outer diameter of $ will be much larger than the outer diameter of the air port lens 4, and the turning time of the cloud and the long time from the soil truck can be single-cut to meet the specifications. SUMMARY OF THE INVENTION Therefore, the object of the present invention, the position, and the mold, is known to provide an accurate eccentricity of the stone, which is formed along the beveled surface, and can prevent the partial meat from simplifying the core picking operation. The 疋-type glass mold is shaped to form a device.

The use of the glass lens 2〇〇 can smoothly prevent Zheng M p from the left eye. The sea-shaped shape of the same piece 20 is demoulded and can be used, so that the glass lens can be finely cored. The above description can further summarize the advantages of the present invention as follows: The restricting cylinder member 20 can guide the broken glass rhyme _, and can be tightly pressed with the seat hole 143 after being swelled by the moon... ΘBetter and better positioning. When the x-glass lens 200 is formed by heating, the tapered surface 23 of the same shape 20 can damage the outer peripheral surface of the glass lens, and the glass-lined lens 200 is Formed as an outer guard 6 gossip H. + Van Wang uniform lens, therefore, the correct core position of the correct core ... not to find no deviation 3 "not only effectively Reducing the core point and the % of the core can improve the eccentricity of the core. 3. By using the tapered hole 24 of the limited-shaped tubular member 2G, the outer diameter of the formed glass lens 200 can be designed to be close to the outer diameter of the finished lens of the finished lens. Thus, the outer peripheral surface of the glass lens can be reduced. The degree of turning can significantly reduce the required turning time. Although only a pair of lower and upper mold cores 12, 32 are shown in Figs. 5 and 7, the mold of the present invention can be simultaneously molded by multiple molds, as will be understood. In addition, as shown in FIG. 8, the lower die unit (7) of the second embodiment of the present invention also has a lower die holder 11', and a mold core 12 disposed under the lower mold base (1) along an axis L. The lower mold base u has a lower mold 13' and a lower mold 13' which are interlocked in the axial direction, and the lower mold core 12 has a column shape and has a lower molding surface 121'. - a lower bearing surface 122 surrounding the lower molding surface 121', and the lower seat hole 143 is formed into a narrow, wide and wide class hole shape, and 10 1252842 Μ - approaching the lower clamping surface 142, the small diameter portion i44, a large diameter portion 145 that approaches (4) the surface 141, and a shoulder surface H6 between them.
