Abstract

The invention relates to the technical field of gas-assisted injection molds, in particular to a gas-assisted flash optical lens injection mold which comprises an upper mold and a lower mold coaxially arranged. An upper mold hole and a lower mold hole form a complete injection molding cavity, and an upper mounting cavity and a lower mounting cavity are formed in the axis positions of the upper mold and the lower mold correspondingly. The upper mounting cavity and the lower mounting cavity are attached to form a complete mounting cavity, an upper connecting channel in the upper mold and a lower connecting channel in the lower mold are spliced between the mounting cavity and each injection molding cavity, the rotating mold is coaxially arranged in the mounting cavity, and an overflow collecting mechanism and a mold hole plugging mechanism are arranged in the rotating mold; and the rotating mold rotates around the axis to enable the flash collecting mechanism and the mold hole blocking mechanism to communicate with the connecting channel. According to the technical scheme, the technical problem of how to prevent redundant materials from remaining in the mold during gas-assisted forming from affecting subsequent machining is solved, and meanwhile, the technical problem of how to reduce burr forming is solved.

Description

technical field [0001] The invention relates to the technical field of gas-assisted injection molds, in particular to a gas-assisted overflow optical lens injection mold. Background technique [0002] Gas-assisted injection molding, also known as gas injection molding, is a new injection molding process and an extension of injection molding. It is developed on the basis of injection molding technology and structural foam injection molding. It can also be considered as a combination of injection molding and hollow molding. A certain kind of composite, the gas-assisted overflow optical lens injection mold with circular cavity distribution in the prior art has many shortcomings. During injection molding, multiple cavities cannot be injected at the same time, which greatly reduces production efficiency and wastes a lot of time. When the gas is injected and squeezed, the excess material cannot be discharged, which makes the material easily overflow to various positions in the mol...
