Problems solved by technology
[0004] However, in this case, the molten plastic does not fill well from the front to the area where the condenser lens is formed
As a result, the molding surface of the condenser lens will be vulnerable to the unbalanced impact of the molten plastic, which is not conducive to the complete molding of the condenser lens, and ultimately affects the optical effect of the condenser lens.
In addition, when the molten plastic reaches the front end of the condenser lens, it will flow to both sides. Thus, the molten plastic will directly impact the insert forming the optical fiber receiving hole in the mold cavity in the transverse direction, and the insert, especially the front end of the insert, will be easily impacted. Deformation or even breakage of the thinner part will affect the final molding of the optical fiber connector and further affect the production yield of the product

Description
technical field [0001] The invention relates to the communication field, in particular to an injection molding device and an injection molding method for an optical fiber connector. Background technique [0002] With the application of optical fiber in the field of communication more and more widely, the electronic signal transmission cable system of many information products, communication audio-visual equipment and other equipment that are widely used nowadays has gradually changed from the early metal wires to high-efficiency optical fiber connectors. The main medium of signal transmission. The optical fiber connector is a device capable of detachable connection between optical fibers. By precisely butting the two end faces of optical fibers, the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, so that The signal is transmitted through the fiber optic core wire housed inside the fiber optic connect...
