[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0018] like Figure 1-Figure 3As shown: a resin lens injection mold with stable bushing positioning in this embodiment includes an upper mold 1 and a lower mold 2, wherein the upper mold 1 is provided with an upper cavity, and the lower mold 2 is provided with a lower cavity, a bushing plate 11 is provided on the edge of the upper mold 1, and an opening 21 is correspondingly provided on the edge of the lower mold 2, and the opening 21 is connected with the lower cavity; when the upper mold 1 and the lower mold 2 are buckled together, the bushing plate 11 is arranged in the opening 21; the inner side of the bushing plate 11 is also provided with a protrusion 111 for demoulding, and the protrusion 111 is arranged in the opening 21.

[0019] In this embodiment, the upper die 1 and the lower die 2 are both cylindrical, and the cross section of the bushing plate 11 is arc-shaped.

[0020] In this embodiment, the upper mold 1 is further provided with an injection hole, and the injection hole is connected with the upper mold cavity through an injection channel.

[0021] In this embodiment, a slide groove 211 parallel to the axis of the cylinder is provided on the side of the opening 21, and a strip protrusion 112111 matching the slide groove 211 is provided on the edge of the bushing plate 11. The strip protrusion 112111 and the strip opening 21 can enhance the sealing between the upper mold 1 and the lower mold 2 to prevent the liquid resin from overflowing.

[0022] In this embodiment, the edge of the upper mold 1 is provided with a plurality of circumferentially arrayed bushing plates 11 , and the edge of the lower mold 2 is provided with a plurality of circumferentially arrayed openings 21 matching the bushing plates 11 .

[0023] The implementation principle of this application is as follows:

[0024] With the cooperation of the bushing plate 11 in the upper mold 1 and the opening 21 in the lower mold 2, the upper cavity of the upper mold 1 and the lower cavity of the lower mold 2 are combined to form a cavity, and the liquid resin is poured into the cavity formed by the upper mold 1 and the lower mold 2 through the injection hole. Due to the effect of the protrusion 111 on the inner side of the bushing plate 11, part of the liquid resin will flow into the cavity formed by the protrusion 111 and the inner wall of the bushing plate 11. After the liquid resin solidifies, when the mold is separated, the protrusion 111 of the bushing plate 11 will lift the parts in the lower mold 2, thereby completing the demolding, and the upper mold 1 and the parts can be demolded through other existing demolding mechanisms.

[0025] The utility model discloses a resin lens injection mold with a stable bushing positioning, comprising an upper mold and a lower mold, wherein the upper mold is provided with an upper cavity, the lower mold is provided with a lower cavity, the edge of the upper mold is provided with a bushing plate, the edge of the lower mold is correspondingly provided with an opening, and the opening is connected with the lower cavity; when the upper mold and the lower mold are buckled, the bushing plate is arranged in the opening; the inner side of the bushing plate is also provided with a protrusion for demoulding, and the protrusion is arranged in the opening. The present application replaces the positioning hole and the positioning column by the cooperation of the bushing plate and the opening, thereby saving mold space. At the same time, when the upper mold and the lower mold are separated, demoulding can also be carried out through the protrusion on the bushing plate, which saves time and labor.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
