Problems solved by technology

[0003] When the sub-mold in the front lens mold is manually inserted into the corresponding installation groove, due to the inaccuracy of manual insertion, it is easy to cause the sub-mold to squeeze or collide with the inner wall of the installation groove, thereby causing damage to the sub-mold. damage, it is impossible to effectively guarantee the accuracy and safety of the sub-mould core during the installation process; and the current special-shaped lens mold core often needs other corresponding fixing structures after being inserted into the installation groove to ensure that the special-shaped lens mold core can be stable Fixed in the installation groove, it is impossible to fix the sub-mould core quickly and easily; at the same time, when the current special-shaped lens mold core is processing the lens, the thickness of the product cannot be freely adjusted according to the actual product needs, which makes the entire spliced ​​special-shaped lens The scope of application of the mold core is very limited

Embodiment 1

[0047] Example 1, such as Figure 1-8 As shown, when the upper lens groove 11 needs to be replaced, the inner threaded ring 203 is first rotated to force the four sets of clamping blocks 210 to leave the inside of the fixing groove 208, thereby releasing the position fixation of the third positioning post 6, and then the third positioning post 6. Take out the sub-mold core composed of the second positioning post 12 and the first positioning post 9 from the inside of the positioning hole 19, and then insert the sub-mold core of a new set of lenses into the inside of the positioning hole 19, and place it on the first positioning post. 9 After entering the inside of the positioning hole 19, manually rotate the internal thread ring 203 to force the rotating ring 202 to follow the rotation, and use the cooperation of the strip chute 206 and the movable column 207 to push the four sets of clamping blocks 210 to approach the first positioning column 9 , until the inner side of the cl...

Embodiment 2

[0048] Example 2, such as Figure 1-3 As shown, when processing special-shaped lenses, the first upper mold base 1 and the second upper mold base 5 are controlled to descend, so that the lower mold base 4 and the second upper mold base 5 are gradually spliced ​​together. 5 After complete splicing and bonding, the lower lens groove 10 and the upper lens groove 11 form a complete injection molding cavity, and then the injection nozzle is inserted into the injection hole 3, and molten raw materials are injected into the injection cavity, until After the raw materials in the injection molding cavity are cooled, the first upper mold base 1 and the second upper mold base 5 are controlled to rise, so that the lower lens groove 10 and the upper lens groove 11 are separated, and finally the special-shaped lens molded inside the lower lens groove 10 is formed. Take it out, and when it is necessary to increase the thickness of the special-shaped lens, turn the connecting cover 8 by a scr...

Abstract

The invention discloses a spliced special-shaped lens mold core and a processing method thereof. The spliced special-shaped lens mold core comprises a first upper mold base, a lower mold base and a second upper mold base, a clamping assembly is jointly arranged between the first upper mold base and the second upper mold base, a positioning hole is jointly formed in the inner side of the first upper mold base and the inner side of the second upper mold base, a third positioning column is arranged at the top of the inner side of the positioning hole, and a second positioning column is installed at the bottom of the third positioning column. Only an internal thread ring needs to be rotated, a rotating ring is forced to rotate along with the internal thread ring, a movable column slides in a strip-shaped sliding groove and gradually moves towards the center of the rotating ring, a first sliding block slides in a first sliding groove, so that four sets of clamping blocks are forced to get close to a third positioning column till the four sets of clamping blocks are all inserted into corresponding fixing grooves, the position of a sub-mold core in the positioning hole is rapidly fixed, the stability of the position of the positioning columns in the positioning hole is greatly guaranteed, and therefore the precision of a lens machined by the special-shaped lens mold core is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lens molds, in particular to a spliced ​​special-shaped lens mold core and a processing method thereof. Background technique [0002] The mold core is a mechanism in the lens mold. For products processed by the mold, the correctness of the product shape depends to a large extent on the manufacturing accuracy of the mold. Taking the lens used in the wafer-level lens as an example, the lens The processing accuracy depends more on the manufacturing accuracy of the lens mold core. [0003] When the sub-mold in the front lens mold is manually inserted into the corresponding installation groove, due to the inaccuracy of manual insertion, it is easy to cause the sub-mold to squeeze or collide with the inner wall of the installation groove, thereby causing damage to the sub-mold. damage, it is impossible to effectively guarantee the accuracy and safety of the sub-mould core during the installation process; and t...
