Description

  The present invention relates to the structure of a hot-press molding device, and in particular, when laminating workpieces, it is not necessary to print a position or mark a symbol, and can perform positioning quickly and accurately. The present invention relates to a hot-press molding apparatus that can prevent a mistake in the stacking order.

  Patent document 1 is illustrated as a conventional hot press molding apparatus. When operating Patent Document 1, an operator needs to sequentially stack a plurality of thermoplastic materials cut into a predetermined shape on a mounting table. Thereafter, a plurality of laminated thermoplastic materials are conveyed below the upper mold using the mounting table. Next, while pressing the lower mounting table with the upper mold by the pressure-increasing cylinder, a plurality of thermoplastic materials on the mounting table are heated using a heater provided on the upper part of the upper mold to perform hot-pressure molding. Complete. Thereby, pressurization and hot melt bonding of a plurality of thermoplastic materials can be performed to obtain a thermoplastic composite material.

  In the conventional hot-press molding apparatus, it is necessary to indicate a positioning symbol on the thermoplastic material of each layer in order to prevent the thermoplastic material from shifting when the operator laminates the thermoplastic material. Thereafter, the operator sequentially stacks the workpieces based on the symbols on the thermoplastic material of each layer. However, since a lot of time is spent notating the positioning symbols, the processing efficiency is affected. Also, in order to prevent the positioning symbol from affecting the aesthetics and quality of the thermoplastic composite after molding, the positioning symbol is generally written so as to be inconspicuous or easily erasable. . For this reason, when stacking workpieces, positioning is difficult or positioning is inaccurate. For example, when the positioning symbol is made smaller than the thermoplastic material of the upper layer, positioning of the thermoplastic material becomes difficult and inaccurate because the positioning symbol is covered with the thermoplastic material of the upper layer. In particular, when the upper thermoplastic material is larger than the lower thermoplastic material, a positioning symbol cannot be provided in advance in the lower thermoplastic material, increasing the difficulty of the laminating operation and significantly affecting the quality. Further, in order for the thermoplastic composite material to have various properties and styles, it is necessary to laminate a plurality of different materials and shapes of thermoplastic materials on the mounting table. Since the order of stacking the thermoplastic materials is different based on the style, if the positioning symbol is not clear or easily disappears, the stacking order is easily mistaken, and the defect rate is greatly increased.
