Problems solved by technology

However, the existing groove mold is difficult to ensure the uniformity of the sample thickness, and the produced samples are very likely to have edge effects, resulting in the sample being thin in the middle and thick at the edge, which affects the accuracy of the performance test sample preparation, and thus makes the test The accuracy and consistency of the results are not high

Embodiment

[0045] see Figure 1-12, the film forming mold in the preferred embodiment of the present invention includes two templates arranged in pairs, that is, the first template 1 and the second template 2, separated by a gasket 3 between the two templates, and a certain shape is formed between the two templates. The wide gap is used for accommodating the mold sheet 4 of corresponding thickness, thereby realizing the forming of the film.

[0046] Specifically, the first formwork 1 and the second formwork 2 in the preferred embodiment respectively have a plate structure, and the two formworks are arranged opposite to each other, and the opposite end surfaces are smooth surfaces parallel to each other, so that the formwork 4 is clamped on both sides. between smooth surfaces. At the same time, in order to realize the accuracy of the distance between the two templates, a plurality of gaskets 3 are arranged between the two templates to ensure that the two templates can be accurately separ...

Abstract

The invention discloses a film forming mold, and belongs to the technical field of material forming, accurate and rapid forming of a film can be realized through corresponding arrangement of two mold plates and a mold sheet between the two mold plates, and films in different forms can be formed by arranging the mold sheet into a replaceable form and utilizing the optimization of different mold sheet thicknesses and different mold sheet cavity forms. The film forming mold disclosed by the invention is simple in structure and simple and convenient to use, can realize rapid and accurate manufacturing of a film sample, avoids the situation of nonuniformity during film manufacturing, and accurately controls the thickness of the sample; and meanwhile, by correspondingly replacing gaskets and the mold sheet, the manufacturing requirements of the films with different sizes and different forms can be met, the compatibility and convenience of the mold are improved, the application cost of a film mold is reduced, and the relatively good practical value and popularization prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of material forming, and in particular relates to a film forming die. Background technique [0002] In the process of laboratory research, it is often encountered that it is necessary to make standard samples. Typically, the material used to make samples in the laboratory is resin or rubber, such as resin castings, vulcanized rubber or thermoplastic rubber. At the same time, most of the molds used to prepare samples using the above materials are groove molds, and the mold materials are mainly polytetrafluoroethylene or silica gel. This is because the characteristics of polytetrafluoroethylene and silica gel are not sticky to resin or rubber, ensuring The performance test samples are easy to demould, thereby ensuring the efficiency of sample production. However, the existing groove mold is difficult to ensure the uniformity of the sample thickness, and the produced samples are very likely to have edge effec...
