Since the upper mold core mold is used for the lower mold core and is used for eccentricity, the assembly of the male mold core is also generated correspondingly. The surface itself has an eccentricity. For example, flute-2, the lens formed by the mold is formed into a lens forming mold, and the shovel ', the lens 1 is the center point of the previous 2 surfaces 22, 24 is not in the form number fine 1 page 4 / total 1? Page 1003271623-0 1352691 On July 27, 100, the replacement page was corrected on the same vertical line, so there is eccentricity. In order to eliminate the eccentricity, it can only be negatively improved by machining. The machining is time-consuming and laborious, which also affects the accuracy of the lens. , surface finish. [0010] Therefore, it is necessary to provide a lens forming mold which can reduce the eccentricity of the lens. SUMMARY OF THE INVENTION [0011] An embodiment of the present invention provides a lens molding die that can reduce lens eccentricity. [0012] In order to achieve the contents of the embodiments, a lens forming mold is provided, comprising: an upper mold core, a mold core corresponding to the upper mold core, and a mold sleeve for mounting the upper mold core and the lower mold core. One end of the lower mold has a convex round table, a side surface of the circular table is formed with a groove, and a side of the mold sleeve is provided with a mounting hole corresponding to the groove, and the lens forming mold further comprises a connecting body and a fixed direction a pin, the connecting body is engaged with the groove through the mounting hole to limit the movement of the lower die, the pin sleeve is formed with a pin hole for receiving the fixing pin, and the lower die is provided with a plurality of positioning holes on the round table. The direction fixing pin • penetrates the pin hole from the outside of the die sleeve and protrudes into one of the plurality of positioning holes, and the direction fixing pin also exposes the outside of the die sleeve. [0013] Compared with the prior art, the lens forming mold provided in this embodiment reduces the eccentricity between the upper mold core and the lower mold core by changing the direction of the lower mold core, and the lower mold core rotates to a certain direction, the upper mold core When the eccentricity of the lower mold core reaches the predetermined requirement, the direction fixing pin cooperates with the positioning hole to fix the lower mold core so as not to rotate, and the desired lens can be formed at this time.

Referring to the second to fifth figures, the lens forming mold 1 for forming the lens 60 is provided in the embodiment, and the lens forming mold j includes: an upper mold core 1 一下, a lower mold core 2 〇, A positioning mechanism 30 between the upper mold core 1 and the lower mold core 2, and a mold sleeve 4 for mounting the upper mold core 1 , the lower mold core 20 and the positioning mechanism 3 . The upper plate may be made of tungsten carbide (wc), sic, yttrium (Si^4), titanium carbide (Tic) or tungsten carbide-cobalt alloy. The upper mold core ίο includes an upper mold body 110, and one end of the upper mold body 11 is formed with a top 120 of the upper mold body UQ concentrically, and the upper mold core & column 12 is provided with an upper molding surface 122. [0017] [0017], is made of carbonized town, carbon cut, nitrogen (four), titanium carbide or carbonized crane #口金. The lower mold core 2 includes a mold core body, and the lower mold body 21 protrudes to form a lower mold core column, and the other end radially extends to form a circular table 2 3 〇. The τ, X lower mold core stud 220 is provided with a molding surface 222 under the upper molding. The side of the truncated cone 230 is recessed to form a groove -Llfir is provided with four positioning holes. The positioning mechanism 30 is a ring-shaped girl, and. The structure can be made of steel, tungsten carbide, tantalum nitride, carbon chinch or reversed tungsten-my alloy. The four-column can be inserted into the positioning mechanism 30. [0018] The die sleeve 40 is a cylindrical structure, and includes a main body portion 410. One end of the main body portion 410 is radially protruded (four) into a flange portion _, and the flange portion 43 is disposed to match the fixed hole 232. When the pin hole 432 and the lower hole die ^~2() are mounted in the die sleeve 40 corresponding to the groove (10), the connecting body 70 is inserted through the women's hole 434 and the groove 234 to fix the lower mold core 2G. In the mold sleeve 4〇094119210 Form No. A0101 Page 6 / 17 page 1003271623-0 1352691 100 years in July 2, at this time, the lower mold core 20 can be rotated within the mold sleeve 4 不可 can not move up and down. The retaining pin can be a cylindrical structure that can extend through the locking aperture 432 and into the locating aperture 232 to secure the lower mold core 20 in a certain direction. [0020] During assembly, the lower mold core 20 extends from one end of the mold sleeve 40 mounting hole 434 into the mold sleeve 40, and the pin hole 432 corresponds to one of the positioning holes 232, and the connecting body 70 is inserted through the mounting hole 434. And extending into the groove 234 to fix the lower mold core 20 in the die sleeve 40, at which time the lower mold core 2 can be rotated, and then the direction fixing pin 50 is inserted through the pin hole 432 into the positioning hole 232 to lower the mold core. The fixing 20 prevents the lower mold core 20 from rotating, and then the positioning mechanism 3 is inserted into the mold sleeve 40 from the other end of the mold sleeve 4 and fits over the lower mold core projection 220. [0021] In use, a preform (not shown) is placed on the lower mold core 20, and then the upper mold core 10 is pressed down, and the upper mold core is pressed down by a distance, and a lens having a certain center thickness can be formed. . [0022] When the detector (not shown) measures the eccentricity between the upper molding surface 1 2 2 and the lower molding surface 2 2 2 by using the detected result, the lower mold core 2 转动 is rotated, and the detector repeatedly detects when When the detection result reaches the predetermined requirement, the rotation of the lower mold core 20 is stopped, and then the direction fixing pin 50 is inserted and penetrated through the pin hole 432 to protrude into the corresponding positioning hole 232 to fix the lower mold core 20. [0023] Please refer to the sixth figure, which is the lens 60 formed by the lens molding die 1 of the embodiment. The surfaces 62 and 64 of the lens 60 correspond to the upper molding surface 122 and the lower molding surface 222 respectively. In the direction, the centers of the upper molding surface 122 and the lower molding surface 222 are brought close to each other, so that the eccentricity between the surfaces 62, 64 of the lens 6 is reduced. [0024] 094119210 In addition, the positioning hole 232 on the lower mold core 20 is not limited to the number of embodiments.
