As shown in fig. 1, a preferred embodiment of the present invention provides a mica part hot pressing mold structure, which is used for hot pressing mica paper to form a mica part 4, the surface of the mica part has protrusions or grooves, the mica part hot pressing mold structure includes:

the templates are respectively arranged in parallel at intervals, and the mica paper to be treated is placed between every two adjacent templates; wherein, be located two at both ends the template still establishes the round bounding wall respectively along its four sides to form respectively upper die 1 and bed die 2, upper die 1 with bed die 2 is set up respectively on the film pressing machine. Except two templates at two ends of all the templates, the rest templates are profiling plates 3 made of heat conducting materials.

For any two adjacent templates, two surfaces, close to each other, of the two templates are respectively provided with a groove or a protrusion matched with the protrusion or the groove of the two surfaces of the mica part to be formed, so that the mica paper to be processed, which is clamped between the two templates, is subjected to hot pressing treatment to obtain the mica part; i.e. the mica paper to be treated, which is sandwiched between the upper die 1 and the profile plates 3, between two adjacent profile plates 3, or between the profile plates 3 and the lower die 2, is subjected to a hot pressing treatment.

In the above embodiment, the mica paper is hot-pressed by using the mica part hot-pressing mold structure, in which a stack of mica paper is placed on the lower mold 2 in order; b, moving the profile plate 3 to the upper surface of the mica paper in the step A, and positioning the profile plate 3 in the process; c, placing another pile of mica paper on the upper surface D of the profiling plate 3 in the step B in order, repeating the actions of B and C, placing for a plurality of times, E, starting a mould pressing machine to close the mould, keeping the temperature and the pressure for tens of minutes, and opening the mould to take out the product.

The number of said cams 3 is not limited and may be one or more than one.

By adopting the mica piece hot-pressing die structure in the embodiment, a plurality of products can be produced by one-time die pressing, the production efficiency is greatly improved, and for a factory, the number of the die pressing machines can be reduced, so that the cost is saved, and meanwhile, the productivity of a single die pressing machine can be multiplied.

It should be further noted that the surface shape of the mica element 4 is not limited, and may be as shown in the schematic drawing, the distribution of the surface protrusions or grooves may be as shown in fig. 1, or may be other shapes, and the shape of the protrusions or grooves may be determined according to the actual situation, and may be a triangle or an arc, and is not limited to the square in fig. 1 of the specification.

The profiling plate 3 has good heat conducting property and can be heated and pressed better and quickly, and the profiling plate 3 is a metal plate or a non-metal plate made of non-metal heat conducting materials. The thickness of the profile plate 3 is designed to meet the strength requirement of hot die pressing, and the profile plate is not required to be too thick, so that the loss of the heat conduction process is reduced as much as possible.
