Molding and punching tool for producing thin-film sheet and manufacture method of thin-film sheet

Abstract

The invention relates to a die for manufacturing film sheets and a method for manufacturing film sheets with the die. The die comprises a first crest slab, a first upper film fixing plate which is fixed under the first crest slab, a first lower film fixing plate, a first upper film insert, a second upper film insert, a first upper film, a first lower film insert, a second lower film insert and a first lower film; the die also comprises a first elastic part, a second elastic part, a return rod and a knockout rod which are used for knocking out and restoration. With the die for manufacturing film sheet, tasks of punching film and hot molding of film which need two sets of dies originally can be fulfilled with one set of dies; therefore, the die number, operators and equipment are decreased and the productivity is promoted and the expenditure is decreased.

Description

technical field [0001] The present invention relates to a forming and punching die for manufacturing film sheet and a method for using the die to manufacture film sheet. Background technique [0002] There are often very beautiful patterns on the surface of car dashboards, air-conditioning panels, mobile phone buttons, casings, window lenses, household appliances, medical equipment and other products, and the pattern is covered with a layer of film sheet. Such a setting , can make the beautiful pattern on the product achieve long-lasting beauty under the protection of the film. Now the production of film sheet is usually to first print out the film blank with pattern and punch out the required positioning holes, then die-cut the film blank, and heat press the film sheet to form. Such processing steps have many procedures, and the required equipment and operators also increase accordingly, and multiple positioning is required, thus resulting in low production efficiency, inc...

AI Technical Summary

Problems solved by technology

[0003] The first technical problem to be solved by the present invention is to address the shortcomings of the existing process from the film blank that has printed the pattern and punched out the positioning hole to the finished film sheet that needs to include a punching die and a forming die. Provide a forming and punching die that only needs one film sheet to complete the above tasks

[0004] The second technical problem to be solved by the present invention is to provide another manufacturing method that requires only two molds for the existing process from the film blank that has printed the pattern and punched out the positioning holes to the film sheet that is completed. A manufacturing method that can be completed using a single forming and die-cutting die for film sheet production
