目前，塑膠射出鏡片模具一般包括一模塊、一模仁及一背板。模塊包括一分模面。分模面開設一貫穿模塊的模仁孔。模仁收容於模仁孔內，其與分模面相背的一端開設有螺孔。背板放置於模塊與分模面相背的表面上，其開設有與螺孔對齊的通孔。塑膠射出鏡片模具還包括一第一螺合部。第一螺合部穿過通孔、螺入螺孔以將背板及模仁固定到模塊上。 At present, plastic injection lens molds generally include a module, a mold core and a back sheet. The module includes a parting surface. The parting surface opens a mold hole that penetrates the module. The mold core is housed in the mold core hole, and a screw hole is opened at one end opposite to the mold part surface. The back plate is placed on the surface of the module opposite to the parting surface, and the through hole is aligned with the screw hole. The plastic injection lens mold further includes a first screwing portion. The first screwing portion passes through the through hole and is screwed into the screw hole to fix the back plate and the mold to the module.
模制鏡片時，由於模仁於模仁孔內的位置會影響射出鏡片的偏心精度。因此，若檢測得出鏡片偏心度不符合要求時，需於模仁孔內旋轉模仁進行偏心度調整。此時，由於模仁與模塊固定，一般需要將第一螺合部螺出，拆開背板與模仁後調整模仁，操作複雜、費時。 When molding the lens, the position of the mold in the hole of the mold will affect the eccentricity of the injection lens. Therefore, if it is found that the lens eccentricity does not meet the requirements, it is necessary to rotate the mold core in the mold core hole to adjust the eccentricity. At this time, since the mold core and the module are fixed, it is generally required to screw out the first screwing portion, and the mold core is adjusted after the back plate and the mold core are disassembled, which is complicated and time consuming.
有鑒於此，有必要提供一種偏心度調整操作簡單的塑膠射出鏡片模具。 In view of this, it is necessary to provide a plastic injection lens mold which is easy to adjust the eccentricity.

請參閱圖5，若利用塑膠射出鏡片模具10成型的鏡片的偏心精度不符合要求，則需要調整模仁120在模仁孔116內的位置，先利用一旋轉件20藉由模塊110的分模面112的卡槽118與模仁120的調整孔126固定，再將固緊的固定件150與定位件140旋轉至鬆開，此時利用旋轉件20旋轉模仁120使模仁120在模仁孔116內調整到所需的位置，然後再將固定件150與定位件140螺合固緊，最後取下旋轉件20，即完成模仁120的位置調整。 Referring to FIG. 5, if the eccentricity of the lens formed by the plastic injection lens mold 10 does not meet the requirements, the position of the mold core 120 in the mold hole 116 needs to be adjusted, and the rotation of the module 110 is first performed by using a rotating member 20. The card slot 118 of the surface 112 is fixed to the adjusting hole 126 of the mold core 120, and then the fixed fixing member 150 and the positioning member 140 are rotated to be loosened. At this time, the mold member 120 is rotated by the rotating member 20 to make the mold core 120 in the mold core. The hole 116 is adjusted to the desired position, and then the fixing member 150 is screwed and fastened to the positioning member 140, and finally the rotating member 20 is removed, that is, the position adjustment of the mold core 120 is completed.
塑膠射出鏡片模具10藉由定位件140與模仁120的固定使背板130固定至模塊110上，同時使固定件150與定位件140可拆卸地連接固定，從而可藉由調節固定件150與定位件140使模仁120可在模仁孔116內被調整，無需拆開背板130，操作方便。 The plastic injection lens mold 10 fixes the back plate 130 to the module 110 by the fixing of the positioning member 140 and the mold core 120, and at the same time, the fixing member 150 and the positioning member 140 are detachably fixed and fixed, so that the fixing member 150 can be adjusted by The positioning member 140 allows the mold core 120 to be adjusted in the mold hole 116 without disassembling the back plate 130, which is convenient to operate.
可以理解，在其他實施方式中，模塊110可開設更多的模仁孔116，塑膠射出鏡片模具10可以包括更多的模仁、定位件及固定件。 It can be understood that in other embodiments, the module 110 can open more mold core holes 116, and the plastic injection lens mold 10 can include more mold cores, positioning members and fixing members.
