Problems solved by technology
After periodical mold closing, the first mold core 12 and the second mold core 14 will be tilted or worn to different degrees in the first mold sleeve 16 and the second mold sleeve 18, which will cause At this time, the joint surface 120 of the first mold core 12 and the mold joint surface 140 of the second mold core 14 cannot be bonded together, so that the manufactured lens will appear eccentric
At the same time, long-term wear will also affect the life of the mold itself

Embodiment Construction
[0013] see figure 2 and image 3 , The lens forming mold 30 of the first embodiment of the present invention includes a first mold core 32 and a second mold core 34 opposite thereto. The first mold core 32 is inserted into and accommodated in a first mold housing 36 , and the second mold core 34 is inserted into and accommodated in a second mold housing 38 .
[0014] Wherein, the opposite end of the first mold core 32 to the second mold core 34 has a first clamping surface 320 , and the first mold clamping surface 320 includes a first molding surface 322 . An end of the second mold core 34 opposite to the first mold core 32 has a second mold surface 340 , and the second mold surface 340 includes a second molding surface 342 . The first mold surface 320 and the second mold surface 340 are opposite and tightly closed when the first mold core 32 and the second mold core 34 are closed, and the first molding surface 322 and the second mold surface 342 are closed. A mold cavity ...

Abstract
The invention relates to an eyeglass forming mould, which comprises a first mould kernel, a second mould kernel relative to the first mould kernel, as well as a first mould sleeve and a second mould sleeve respectively sleeved outside the first mould kernel and the second mould kernel. The eyeglass forming mould further comprises a plurality of positioning parts, a plurality of positioning holes,a plurality of through-holes, and the positioning parts, wherein a plurality of positioning holes are formed on the outer side faces of the first mould kernel and the second mould kernel at equal intervals; a plurality of through-holes which are corresponding to the positions of the positioning holes of the first mould kernel and the second mould kernel and have the diameter matched with the first mould kernel and the second mould kernel are respectively arranged on the first mould sleeve and the second mould sleeve; the positioning parts penetrates through the through holes and revolves intothe positioning holes. The eyeglass forming mould has the advantages of stability and higher precision.
Description
technical field [0001] The invention relates to a mold, in particular to a lens forming mold. Background technique [0002] With the continuous development of science and technology, portable electronic devices, such as mobile phones, are widely used and tend to be lightweight, beautiful and multi-functional. Among them, the camera function is an additional function of the newly developed portable electronic device in recent years. Mobile phones with digital cameras are more and more favored by users because they can realize the instant shooting function and are easy to use. Due to the small volume of the mobile phone, the camera module installed in the mobile phone needs to have a small volume. While people are pursuing the miniaturization of digital camera modules for mobile phones, they also put forward higher requirements for its imaging quality. The imaging quality of objects depends to a large extent on the quality of the optical lenses in the camera module, and The...
