Optical mold structure capable of simultaneously injecting two materials

Abstract

The utility model discloses an optical mould structure capable of simultaneously injecting two materials, which comprises a lower mounting seat and an upper mounting seat, the bottom of the upper mounting seat is fixedly connected with an upper mould, main circulating pipes are arranged in the upper mould and the upper mounting seat, the top of the lower mounting seat is fixedly connected with a lower mould, and the lower mould is fixedly connected with the lower mounting seat. A convex face die head is fixedly connected in the lower die, two interval plastic parts are connected to the upper surface of the convex face die head in a clamped mode, a single-head circulation groove is formed between the upper die and the lower die, the single-head circulation groove is communicated with the main circulation pipe, a double-head circulation groove is formed between the upper die and the lower die, and an auxiliary circulation pipe is connected to the top of the lower installation base in an embedded mode. According to the utility model, one kind of liquid is injected between the two spaced plastic parts from the main circulating pipe and the single-head circulating groove, and meanwhile, the other kind of liquid is injected outside the two spaced plastic parts from the auxiliary circulating pipe and the double-head circulating groove, so that two different materials are simultaneously injected, and the error of the plastic parts is further reduced.
