Description of the invention: [Technical field of invention] The present invention relates to a method and structure for manufacturing a continuous plastic die for a plastic plastic, in particular to a plastic roll extruded from a plastic extruder to be heated into a ribbon-shaped plastic plate and maintained in plasticity. In the state, the strip plastic plate is processed into a semi-finished product by the molding device, and the semi-finished product is released from the molding device, so that the plastic material does not need to be heated a plurality of times to cause plastic quality change and waste of energy. [Prior Art] The process of vacuuming or sizing is one of the methods for manufacturing a finished plastic product, which has the advantages of rapid production and high accuracy, and is especially widely used in the manufacture of plastic thin shells. Please refer to the first figure, which is a schematic diagram of the processing process of the conventional plastic product mold. First, the plastic material is extruded into a piece of plastic plate, and then the formed plastic plate is cut. After being cut into a predetermined area and size, the cut plastic sheet is heated to a softened state of melting, that is, in a plastic state, and placed in a processing mold to be shaped into a semi-finished product by vacuum forming, and the semi-finished product is removed from the processing mold again. Processing and finishing, it is a finished product that can be sold. Please refer to the second figure, which is a simple structural diagram required for the processing of a conventional plastic product mold, wherein the plastic product processing mold (8) comprises a heating plate (81), a clamp (82), and a bottom. a die (83) and a vacuuming device (84) having a recess (831) of a desired predetermined shape, the vacuuming device (84) including an air passage 1306806 (841) to the bottom The pockets (831) of the mold (83) are in communication. When manufacturing, the plastic plate (85) which has been cut into the appropriate area size is firstly fixed by the clamp (82), and then the heating plate (81) is used for the plastic plate. (85) heating to the plastic plate (85) to soften, then covering the plastic plate (85) above the bottom mold (83) to seal the recess (831), and then passing the vacuum through the vacuum device (84) The air passage (841) removes the air in the recess (831), and deforms the plastic plate (85) against the bottom of the bottom mold (83) by the pressure difference between the inside and outside of the bottom mold (83). After cooling and setting, you can exit the bottom mold (83) and become a semi-finished product (86). Referring to the third figure, it is another single structural schematic diagram of a conventional plastic product processing wedge, wherein the plastic product processing mold (9) comprises a heating plate (91), a clamp (92), a bottom mold (93) having a recess (931), a vacuuming device (94) and a die upper mold (95), the vacuuming device (94) having an air passage (941) to the bottom mold The pockets (931) of (93) are connected, and when the plastic plate (96) is heated by the heating plate (91), the pressure is generated by the vacuum device φ (94). By pressing the upper die (95) toward the recess (931) of the bottom mold (93), the thickness and shape of the formed plastic plate (96) are more uniform. However, the above conventional manufacturing method or structure still has the following disadvantages: - 1. Time-consuming labor: The plastic material needs to be heated one time when it is made into a plastic plate: • The plastic plate is cut into a predetermined size and is shaped before being shaped. It needs to be heated once more, each heating time is long and time consuming. Moreover, the plastic plate needs to be cut into a predetermined size before entering the mold processing. This processing step needs to calculate its accuracy and bear the probability of processing failure in advance. At the same time, l3〇68〇6 is laborious. 2. Decrease in material properties: Conventional technology requires multiple heating and cooling of plastic materials, so that the material's thermal history material degradation may affect the overall structure of the finished product. 3. The heating quality is not easy to control: the heating of the plastic plate in a single direction of the heating plate tends to make the various parts of the plastic plate unheated, and it is more likely that the hard outer layer of the inner layer is soft, which causes the thickness of the plastic plate to be limited and cannot be uniformly formed. 4. Energy waste: The process of multiple cooling and heating of plastic sheets incurs energy waste and increased production costs. In view of this, the inventor of the present case has accumulated many years of design and manufacture of the inspections.
