Description
Technical field
The present invention relates to a kind of heat pressing forming device and method thereof, particularly relate to a kind of a kind of heat pressing forming device and method thereof that the glue that overflows is avoided flash and burr of holding.
Background technology
Known LGP (Light Guide Panel, LGP) thermoforming way is that thing to be imprinted is positioned in the die cavity of impressing mould, and impressing mould comprises cope match-plate pattern, and cope match-plate pattern respectively has the impression face of impression optical grains.Thing to be imprinted is placed after the cope match-plate pattern surface with impression optical grains closed this impressing mould.At this moment, cope match-plate pattern can form a sealing die cavity, and impressing mould can make thing to be imprinted softening to plastic state by heating.Then, apply pressure to thing to be imprinted by impressing mould again, make impression lines moulding on thing to be imprinted of cope match-plate pattern, cooled off again at last thing to be imprinted, can take out products formed after impressing mould is opened.
Yet pressue device of the prior art is with oil pressure, air pressure or other drivers source as output pressure, cooperates bent axle or axle directly to link impressing mould and applies pressure to template.Yet, be large-area plane compared to template, can regard as a little with the pressure of bent axle or axle transmission template and exert pressure, so be difficult for making template to reach comprehensive pressurized.
In other words, the thing to be imprinted of pressurized by the pressure of bent axle or axle transmission template, its pressure that is subject to is also inhomogeneous, so the yield of impression finished product is difficult for promoting, and the size of impression finished product only can the moulding small sized article, the follow-up pressue device that has in addition multiaxis to exert pressure occurs and uses silica gel plate to make fender, and its effect only has a little improvement.
In addition, known heater is at cope match-plate pattern or impressing mould boring arranges the water route, passes to hot liquid or cold heating liquid again or cools off thing to be imprinted.Simultaneously, also have with heat pipe and water route cross-over configuration, heat pipe is used for heating thing to be imprinted, passes to cold liquid cools thing to be imprinted in the water route again.From above-mentioned known mode of heating can learn all must heat first the impressing mould body after, via heat conduction heat energy is reached thing to be imprinted again.But, the transmission of this kind mode heat energy is easily because the position that size, heating tube or the water route of impressing mould are buried underground and the reasons such as size of thing to be imprinted, transmit variable speed and form, and then the softening uneven phenomenon of thing to be imprinted occurs, the yield that therefore impresses finished product is not easy to promote.
In general, the optical grains on the template is quite meticulous lines, especially microstructure graph.If it should be noted that the template plane, make easily deposits yields burr to be imprinted or cause flash all around during impression.In order to solve the flash of deposits yields burr to be imprinted, necessary secondary operations is to remove burr.Yet template and mould all are quite meticulous structures, in case produce flash, may make the particle of flash fall into template and mould, cause whole group of device to damage.
Therefore, with demand, design a hot-press molding method and device thereof, effectively solve the problem that known technology causes, an instant subject under discussion that has become market to use.
