Description
Technical field
The present invention is relevant for a kind of film vacuum forming method and device thereof; Especially finger is a kind of can avoid heat energy loss and then make full use of heat energy; Make film shaped activity duration shortening, output increase, and can specifically reduce the film vacuum forming method and the device thereof of equipment cost.
Background technology
Press, existing film vacuum forming method is shown in figure 13, and it comprises: (1) places on the mould 91 with film; (2) electric heater is moved to the film top, to the film heating, make film temperature rise to deformation temperature 92 behind the sealing cover; (3) shift out electric heater 93; (4) insert the high pressure sealing cover; (5) with vacuumizing 94 between film and die surface; (6) film surface is applied high pressure, make film be affixed on die surface 95; (7) under uncolled mould state, make film shaped setting 96; (8) take off finished product 97 (uncolled).
Though the aforementioned film vacuum forming method that should have now can carry out the production of film implements, yet, still have disappearance to exist in its production method; For example, be that electric heater is shifted out at the third step of its method, the 4th step is inserted the high pressure sealing cover again; And then subsequent step such as vacuumize, add high pressure; To make that so the production effect is not good enough, and insert the high pressure sealing cover behind the electric heater again and can cause film temperature original (electric heater do not remove before) to reduce more than 2-3 ℃ that apply positive negative pressure to film (especially thickness is greater than more than the 0.5mm) this moment again because of removing; With its attaching degree that is attached on the mould is added to the difficulties, so generally need to use high pressure (100kg/cm
2More than) pressure that makes attaches, this will make that high-tension apparatus is with high costs, and process time is longer; Add the time consumption that electric heater shifts out before finished product is shaped; Again, take off finished product before finished product is uncolled for it, finished product is easily deformable; Make whole prouctiveness and quality to improve, and the design of nonideal film vacuum forming method.Therefore, how thoroughly improving to the existing disappearance problem that its prouctiveness of film vacuum forming method is relatively poor, cost equipment is high, really is that industry remains the emphasis direction probing into, break through
Do not attain the desirable fact in view of having now in its disappearance manufactured of film vacuum forming method and method thereof, the equipment design; The inventor is based on being engaged in the experience that this already researches and develops design for many years; Set about researching and developing its solution; Hope can be developed a kind of film vacuum forming method and device thereof of making economic benefit and product competitiveness that have more, and to promote the development of this industry, satisfying through for a long time design has generation of the present invention.
