Embodiment Construction

[0028] In the following embodiments, the principle of hot pressing is mainly to transfer heat energy to the cut piece through the mold to make it shaped, or to weld the two cut pieces together. Welding is to use energy to combine two or more pieces of materials, let the welding surface reach its activation temperature through heat transfer, and use positive pressure to make the welding surface produce mechanical bonding force in the interface area after solidification, and the two welding surfaces Due to the transmission of high temperature, the molecules absorb energy to generate intermolecular force, and then make the two pieces produce sufficient bonding strength.

[0029] In an embodiment of the present invention, heat is generated during heat transfer by converting electric energy into thermal energy by controlling the electric heating tube through an electric control system. The electric control system has an electric control interface, which includes temperature setting...

Abstract

The invention relates to a hot press molding process, a molding system and a mould group thereof, which can replace the conventional stitching manufacture manner. A first mould is provided with an annular hot press part, a second mould is provided with a hot press surface, a plurality of air absorbing holes are formed in an outer ring of the hot press surface, an air duct is internally arranged in the second mould and is used for connecting an air source, the air absorbing holes are communicated with the air duct, an outer ring cutting sheet is sleeved on the sidewall of the second mould so that a flange of the outer ring cutting sheet faces the hot press surface of the second mould, an air absorbing system is used for absorbing air in the air duct of the second mould so that the flange of the outer ring cutting sheet is smoothly located on the outer ring of the hot press surface depending on the air absorbing holes, the hot press part of the first mould is heated, and the flange of the outer ring cutting sheet is pressed in a hot state by the hot press part so as to enable the flange to be molded; in addition, a central cutting sheet is arranged on the outer ring cutting sheet, and the central cutting sheet and the flange of the outer ring cutting sheet are melted by utilizing the hot press part of the first mould.

Description

technical field [0001] The invention relates to a thermocompression forming system and process, in particular to a backpack thermocompression forming system and process. Background technique [0002] Due to the complicated production process of the traditional seamless fusion backpack, it has to rely on a lot of manual craftsmanship. In addition to the extremely long working hours, excessive manpower allocation and material loss add a lot of unnecessary costs, and the finished product is often due to The quality varies depending on the operator. Contents of the invention [0003] Aiming at the foregoing problems, a thermoforming process, a forming system and a mold set thereof are provided to replace the traditional sewing method. [0004] A mold set for a hot pressing forming process is characterized in that it includes a first mold and a second mold, the first mold has a ring-shaped hot pressing part, the second mold is provided with a hot pressing surface, and the oute...
