Technical Field

[0001] The utility model relates to the technical field of flat knife moulds, in particular to a new type of top block device mould for a flat knife. Background Art

[0002] In recent years, with the continuous development of electronic technology, electronic products are constantly updated, the size of their working components is getting smaller, the working speed and efficiency are getting higher, and the heat generation is getting larger. Therefore, it is not only required to be equipped with corresponding thermal conductive heat dissipation elements, but also to ensure that the thermal conductive heat dissipation elements have stronger thermal conductive heat dissipation capabilities to ensure the reliability of product performance and extend its service life. Graphite, as a thermal conductive heat dissipation material, has become the preferred material for modern electronic products to solve thermal conductive heat dissipation technology due to its unique low density, high thermal conductivity and heat dissipation coefficient and low thermal resistance. The heat dissipation graphite sheet can not only dissipate heat in the horizontal direction, but also in the vertical direction. In particular, the use of a lamellar structure can not only make it better suitable for the surface of any product, but also effectively play the role of thermal conductivity and heat dissipation. Die-cutting is to form customized product parts of different sizes through a mold according to a predetermined shape. In the production process of graphite sheets, a die-cutting flat knife mold needs to be used for die-cutting. The utility model is a flat knife new top block device mold.
