Problems solved by technology
[0002] With the rapid development of science and technology, the vision of more and more people is declining faster, which has also led to the development of the glasses industry, which mainly includes spectacle frames, spectacle lenses and spectacle cases. In the prior art, spectacle cases usually It is produced by batch processing of molds, which can save a lot of cost and make it more competitive in the market. However, the glasses cases produced by existing molds are usually small in size and require secondary processing, which affects their commercial competitiveness.

Embodiment Construction
[0026] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the invention is not limited to these embodiments.
[0027] Such as Figure 1-3 Shown, a kind of spectacle case production mold comprises:
[0028] The punch 100, the punch 100 is a movable mold, in the process of mold closing and mold opening, it is all completed by the movement of the punch 100.
[0029] The concave mold 200, the concave mold 200 and the punch mold 100 are molded together to form a cavity, the concave mold 200 is provided with an inlet runner 210 and an inlet gate 220, and the two ends of the inlet runner 210 are respectively connected to both sides of the cavity, The gate 220 communicates with the middle part of the pouring runner 210, and the mold cavity formed by the mating of the concave mold 200 and the punch 100 determines the shape of the produced product....

The invention discloses a spectacle case production mold and its production industry, which belongs to the technical field of moulds, and solves the problem that the size of the spectacle case produced by the existing spectacle case production mold is not standard. The spectacle case production mold includes a convex mold and a concave mold. By setting the inlet runner vertically to connect with the inlet gate of the cavity, the volume at the inlet gate of the cavity is ensured at the same time. The distance between them is smaller than the distance between the lateral sides of the cavity, thereby shortening the length of the inlet runner, reducing the heat loss of the liquid material in the inlet runner, and avoiding the preservation caused by cooling and condensation at the inlet. If the pressure is not in place, the size will be non-standard. The production mold of this spectacle case has the advantage of standard product size.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to a production mold and a production process for a spectacle case. Background technique [0002] With the rapid development of science and technology, the vision of more and more people is declining faster, which has also led to the development of the glasses industry, which mainly includes spectacle frames, spectacle lenses and spectacle cases. In the prior art, spectacle cases usually Batch processing of molds can save a lot of cost and make it more competitive in the market. However, the glasses cases produced by existing molds are usually small in size and require secondary processing, which affects their commercial competitiveness. Contents of the invention [0003] The present invention is made in consideration of the foregoing problems, and the purpose of the invention is to provide a production mold and production process for a spectacle case, which can reach the standard s...
