Description of the Invention: [Technical Field] The present invention relates to a forming apparatus, and more particularly to a glass mold forming apparatus capable of simplifying the disassembly and assembly procedure of a continuous glass mold forming system. [Prior Art] 1 is a conventional mold for forming an optical glass lens, comprising an inner sleeve 1, a set of lower mold cores 2 which are connected to the inner sleeve and can be placed by a glass nitrate material 5. An upper mold core 3 movably sleeved in the inner sleeve, and an outer sleeve 4 detachably assembled outside the inner sleeve 1. As shown in FIG. 2, a conventional continuous glass mold forming system for forming an optical glass lens generally includes a forming chamber 7, a heating station 7, a first pressurizing station 702, and a second pressurizing station 703. A cooling station 704, a first disassembly station 705, a second disassembly station 706, a replacement station 707, a first, clothing station 708, and a second assembly station 7〇9. When the forming system starts to continuously produce the glass lens, the mold together with the glass nitrate material 5 is moved to the heating station 7 formed into the 7 to make the glass nitrate material 5 heated and softened; then, the mold will be sequentially It is pushed to the first and second pressurizing stations 7〇2, 7〇3. At this time, the upper pressing plates of the first and second pressurizing stations 702 and 7〇3 are moved down to -i: 4 The top end of the sleeve 4 is such that the top end of the upper mold core 3 is flush with the top end of the outer casing 4, and further the softened glass stone material is pressure-formed into a glass lens 6; then, the mold together with the glass The lens 6 is sequentially transported to the cooling station 7G4 to cool the glass lens 6; and, when the mold and the glass lens 6 are removed from the forming chamber 7, the mold 1272255 is moved to The first dismantling station) removes the material sleeve 4 by a robot arm (not shown); then, the inner sleeve i and the upper and lower mold cores 3, 2 are moved to the second disassembly Station) clamp the inner sleeve! And borrowing another machine jaw (not shown, the other mechanical arm (not shown) removes the upper =, the receiver, the inner sleeve 1 and the lower mold 2 will be moved to the replacement station 707, in order to remove the glass lens 6 for the lower mold core 2; then, the inner 1: placing another glass nitrate material 5 to the 卞-u and the lower mold core 2 will be moved ^ 3 7〇8' to borrow another mechanical arm (not shown) and another: two into the inner sleeve ^ Then, the inner sleeve 1 and the upper two 2 will be moved to the second group of stations 7 ° 9. The other outer sleeve 4 is assembled outside the inner sleeve i by means of a further machine diagram, after which the mold is moved along with the other broken text. Formed to the next cycle of production. Thus, the forming system continuously molds the glass nitrate material 5 in the mold into the glass mirror 6. Although the mold is available for recycling in the forming system, the glass nitrate material 5 is continuously formed into the glass sheet 6, but in the case of the mold, the mold has the following defects. The inner and outer sleeves 1 and 4 of the mold are usually only processed to a general fit precision (about 2〇χ 1〇-5m~3〇χ i〇_5m), and the upper and lower: two 3 The fit between the 2 and the inner sleeve 1 is processed to a more precise δ precision (about 2~3# m). In addition, there is no blocking between the inner and outer sleeves 4. Construction, therefore, in the removal of the upper mold 3 inch 'if the outer sleeve 4 is not removed first', when the upper mold 3 is pulled up by the robot arm, since the inner sleeve is the same The upper mold 3 is precisely matched, and the inner sleeve 1 is not restrained by any structure, so the inner sleeve 1 tends to move up with the upper mold 3 relative to the outer sleeve 4, and Resulting in poor demolding, according to which the forming system must be provided before the second dismantling station 706, and a first disassembling station 705 for removing the outer sleeve 4 is additionally provided. The associated robot arm, and thus the second assembly station 7〇9 and the associated robot arm for assembling the outer sleeve 4, must also be provided after the first assembly station 708, so that not only the mold is dismantled The assembly process is complicated and the equipment cost of the forming system is increased. 2. When the mold is moved between the heating station 7〇1, the first and second pressurizing stations, 703 and the cooling station 704, since the bottom end of the outer sleeve 4 is directly abutted The bottom plate of the station moves and moves relative to the bottom plate of the stations. Therefore, the operator cannot position a gasket (not shown) at the bottom end of the outer sleeve 4 and the bottom plate of the stations. In this way, the operator cannot finely adjust the center thickness of the formed glass lens 6 by changing the tip height of the outer (four) 4 . SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to simplify the disassembly procedure, that is, to provide a glass mold forming device which can simplify the disassembly and assembly procedure of the continuous glass mold forming system and finely adjust the center of the formed glass lens. thickness. The glass mold forming device which can simplify the disassembly and assembly procedure can be used to form a glass stone material having a thermal expansion coefficient into a glass lens, and the glass mold forming device comprises an outer sleeve, an inner sleeve and a lower mold. Ren, and - on the mold. The outer sleeve has a first and a first by the first peripheral wall I272255

As shown in Figures 4 and 5, the present invention can be recycled to a continuous glass mold forming system for forming optical glass lenses. The forming system includes a forming chamber 300, a heating station 310, and a first pressurizing station 320. A second pressurizing station 330, a cooling station 340, a disassembling station 350, a receiving station 36A, and an assembly station 370. When the forming system begins to continuously produce a glass lens, the present invention, along with the glass nitrate 100, is moved to a heating station 3 10 in the forming chamber 3, the heating temperature of the heating station 3 10 is about the softening temperature of the glass nitrate material. Above one Baidu, the glass nitrate material can be heated and softened; then the invention is sequentially pushed to the first pressure station 320, and the heating temperature of the first pressure station 320 is about softened in the glass nitrate material. 50 degrees above the temperature point, since the first thermal expansion coefficient α1 of the outer sleeve 是 is greater than the thermal expansion coefficient α of the glass material 100, the second thermal expansion coefficient α2 of the inner sleeve 20, and the lower mold core 30 The third coefficient of thermal expansion α 3 and the fourth coefficient of thermal expansion of the upper mold core 4 ', therefore, the expansion amount of the outer sleeve 1G is much larger than the glass stone material UK), the inner sleeve 20, the lower mold core 3 〇 该 该 该 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 The first pressure station 32 〇 a forceshikou roof 321 moves down Pressing on the first-top surface (1) of the outer sleeve 1〇, the upper moving plate 3 2 1 can be 兮 伊 伊 γ 6 into the second socket of the 5 杈 upper 杈 40 40 ' π king is pressed into the inside of the inner hole 12 of the brother, and the upper mold is moved to the top surface 45 盥兮笙 ^ /, = Haidi - the top surface 112 is flush, and thus the 3 11 1272255 The glass material 100 is initially formed into a thin glass lens. During this process, the gas of the inner sleeve 20 can escape from the gap between the inner and outer sleeves and the inner hole through the escape holes 216. To the outside; then, the present invention is sequentially pushed to the second station 330. The heating temperature of the second station 33 is lower than the temperature-down station 320, below the glass transition temperature point. Twenty degrees. Since the heating sleeve is lowered from the first transfer station 32〇 to the second pressurizing station 33〇, the shrinkage amount of the outer sleeve 1G is much larger than the glass nitrate material _, the inner sleeve 胄20, The lower mold core 3〇 and the upper mold core 4〇 (for the sake of clarity, in the drawing, the shrinkage # is enlarged), therefore, when the upper pressurizing plate 331 of the second pressurizing station 330 is pressed down When the first top end face ι 2 of the outer sleeve 1〇 is placed, the upper pressing plate 331 can continue to dust the upper mold core 4G as the outer sleeve 1() contracts, thereby making the top end face 45 continuously with the first top moon, so that the center thickness of the glass lens can be stably and precisely controlled, and the first and second shaping shapes can be accurately transferred to the glass. (4) on the surface; then, the present invention is sequentially pushed to the cooling station 34() together with the glass lens, so that the glass lens 200 is cooled to a normal temperature and shaped; then, when the present invention is accompanied by the glass lens 200 Moving out of the forming chamber class &, the invention will be moved to the dismantling station 350' to be removed by a mechanical arm (not shown) The upper mold core 4〇, in the process, since the first bearing surface (1) of the outer sleeve 1〇 can abut the second bearing surface (1) of the inner sleeve 2G, the inner sleeve is restrained Therefore, when the mechanical jaw (Fig. 4) clamps the outer sleeve ig, the robot arm can smoothly move the upper mold core 4G away from the inner and outer sleeves 2, then The outer sleeves 20, 10 and the lower mold core 3 are moved 12 1272255 to the transfer station 360' to remove the glass lens 200, and another glass nitrate material 1 is placed in the lower mold core 3 Then, the inner and outer sleeves, 1 〇 and the lower mold core 30 are moved to the assembly station 370 to join another upper mold core by another mechanical arm (not shown). The inner and outer sleeves (9), 10, and the present invention, together with the other glass nitrate material, are again moved into the forming t 300 for the next-stage cycle production process. Thus, the forming system can continuously form the (4) glass nitrate mold of the present invention into the glass lens 200. Through the above description, the advantages of the present invention can be further summarized as follows: - The first bearing surface (1) of the outer sleeve 1G of the present invention can abut against the second bearing surface 213 of the inner sleeve 20, and The inner sleeve 2 is limited, so that when the present invention is moved to the disassembly station 35G, and the outer claw 1G is sweetened by the machine claw (not shown), the machine f (the figure is not The upper right armor 40 can be grasped, and the ya hai hai ren ren 4 〇 smoothly moves upwardly away from the inner and outer sleeves 20, 10'. Therefore, the present invention can be used without removing the outer sleeve. The forming system smoothly removes the upper mold 〇4〇, and can effectively prevent the inner sleeve 20 from being displaced with the upper mold core 4Q to cause mold release failure. - The forming system cooperating with the present invention does not need to be separately set. Stations = in addition to the outer pure 10', of course, there is no need to set up another station to assemble the jacket η ίο Compared with the forming system of Baizhi, the forming system matched with the present invention can not only simplify the overall disassembly and assembly process , which can effectively reduce the overall equipment cost. As shown in Fig. 6, it is a preferred embodiment of the two brothers. The second preferred embodiment is similar to the first preferred embodiment, and the difference is that 13 1272255. The second preferred embodiment further includes a spacer 5〇 disposed on the inner sleeve. The second bottom end surface 215 of the second peripheral wall 21 of the barrel 20 is between the annular shoulder surface 33 of the lower mold core 30. Thus, the second preferred embodiment can achieve the same as the above-described first preferred embodiment. In addition to the purpose and effect, the operator can further change the height of the top end surface 45 of the outer sleeve 1 by the height of the top end surface 45 of the outer sleeve 1 by the spacer 50, thereby fine-tuning the formed glass lens. The center thickness of 200. / In summary, the glass mold forming device of the present invention which simplifies the disassembly and assembly procedure can not only simplify the disassembly and assembly process of the continuous glass mold forming system, but also reduce the equipment cost of the forming system, and can be used by the mat.
