Description
Technical field
The present invention be directed to a kind of brand-new designs of the continuous atmosphere sintering molding machine of air hermetic of hot press formed product, special
It is not a kind of to have that continuous, high efficiency, high quality be hot-forming, more uniform temperature in thermal field, the gas for reducing heat loss in thermal field
Close formula continuous hot-press molding machine.
Background technology
Hot-forming is a kind of processing method of high molecular material, will mainly have certain thickness material and is placed in mold
In, heating mould or environment are made material softening and are covered in die surface, then extruded with machine, after cooling stage cures,
Hot-forming product just can be obtained.
Hot-forming material, by taking glass as an example, glass is because have the characteristic of higher light transmission, therefore show equipment (such as
The electronic products such as mobile phone, wrist-watch) multiselect its shell as window portion.It can be seen that handheld electric products surface is typically provided with glass
Shell, to protect the display module of interiors of products.Glass shell is all largely the shape of tablet at present, so in electronic product
Upper surface can form seam.Further, since the periphery of electronic product must retain the mechanism section of one fixed width, to solid
Fixed flat glass, therefore the top surface of electronic product also can not be just utilized completely.Currently, three-dimensional or bend glass is gradually
Be employed on the glass shell of electronic product.
Flat glass shell is easier to manufacture, and the manufacture of the glass shell with three-dimensional shape is then more not easy.Currently, tool
There is the manufacture of the glass shell of three-dimensional shape usually there are two types of method, the first is：The flat glass unit of multi-disc is manufactured, then
Glass shell with three-dimensional shape is formed by the mode at stickup edge；It is for second：Certain thickness cuboid glass is manufactured,
Then in grinding multiple on the cuboid glass to be formed with multi-sided three-dimensional contouring.However, above-mentioned two kinds of methods are equal
It takes time and effort, speed of production is very slow.Generally, due to which glass material is for a tabular, made if to produce one and have
The glass of type, the preferable practice are that flat glass material is set to a upper mould piece and once between module, is then heated
Upper mould piece, lower module and glass material, so that glass material softens, when above-mentioned glass material softens, upper mould piece and lower die
Part can carry out die closing operation, so that upper mould piece moulds the shape of glass material along a molding direction jointly with lower module, with life
Produce corresponding moulded glass.China's patent announcement M452174 patent names are for manufacturing the former of moulded glass
(the patent announcement data reference of May 01 2013 day for announcing), it includes have a parent form mold members, one first male mold members,
One second male mold members, a supporting post-rod and a compression bar.The first male mold members are set to this in a manner of openable and closable
In parent form mold members, which is set between the parent form mold members and the first male mold members.The support
Mandril is arranged in the parent form mold members, which is used for ejection in the second male mold members, to support second male
A moulded glass is clamped with the first male mold members in mold members jointly.The compression bar is set to the one of the first male mold members
Side, the compression bar are pressed on the first male mold members under being used for, so that the first male mold members and the second male mold members phase
One die-closed position is moved to the parent form mold members, to be molded the moulded glass.However it is continuous, quick to be still unable to reach industry
The demand for manufacturing high quality model solid glass, lacks for it.
The notification number that present invention applicant is previously proposed patented power is that M536234 patent names are that air hermetic model is vertical
Body glass apparatus for continuous formation is a kind of brand-new design for the apparatus for continuous formation of model solid glass product design,
It is mainly closed by furnace body, and two ends are equipped with exchange system outside furnace body, and furnace interior is equipped with air-tight cavity；Exchange system,
It is set to two end of furnace body, is equipped with outer feed track between two end exchange system of furnace body, each exchange system includes to be set to furnace body side
Interior gas-tight door and the outer gas-tight door for being set to outer feed track side, form airtight space, and be equipped between interior gas-tight door and outer gas-tight door
Support plate is pushed into or is removed furnace body by gearshift；Air-tight cavity is set to furnace interior, includes air tight housing, in air tight housing
With interior feed track, gas-tight door in interior feed track connection two end exchange system of furnace body, and it is equipped with sliding rail, using what is moved as support plate
Track, the air-tight cavity are air hermetic, and import protective gas, and have heating zone, high-temperature molding area and cold according to manufacturing process differentiation
But at least one layer of insulation layer is equipped in area, heating zone and high-temperature molding area, and insulation layer center forms thermal field, is equipped with and regards in thermal field
There is cooling device, high-temperature molding area to be equipped with compression system for the heating component of manufacturing process required temperature, cooling zone；Outer conveying
Road connects two end exchange system of furnace body；Compression system is mainly made of cylinder pressure, pressuring shaft and pressured column；Thus configured originally
Invention, plate glass to be formed are placed in mould surface, and mold is then placed on support plate, and support plate enters airtight through exchange system
Chamber, the high temperature of preheating and high-temperature molding area through heating zone make Glass Transition in mould, and are pressurizeed by compression system and be molded, then
It after cooling zone cools down, is sent out outside furnace body through exchange system, then demould, can also reach continuous, high efficiency and height really
Quality is molded the effect of model solid glass.However since glass transition temperature now is higher and higher, it is soft especially to contain lead glass
Change temperature higher, in addition, hot-forming material in addition to glass, such as metal, ceramics or cermet heterogeneous material compound
It is hot-forming, due in air tight housing thermal field to temperature requirement higher, will evenly, it is necessary to for molding machine really
Thermal field etc. proposes more preferably effective design scheme, so that continuous hot-press molding machine is more they tended to perfect.
