Description
Technical field
It the utility model is related to lucite field, and in particular to a kind of lucite blows drawing thermal forming device.
Background technology
Lucite be using methyl methacrylate monomer as raw material, by specific chemical molecular design with it is modified and
Polymerisation and high-temperature process form.Its product has that bending strength is big, shock resistance is good, light transmission is good, chemically stable
The advantages that property is good, good weatherability.Lucite hemisphere, lucite ball and other shapes of lucite case class product are
It is widely used in the fields such as business, light industry, building, chemical industry, such as lampshade, dome skylight, dust cover, protective cover, aquarium, technique system
Product etc..The production of hemispherical lucite at present be typically by blow molding or the mode of drawing and forming, which production
Lucite stretching is uneven, causes printing opacity uneven and profile has flaw lamp problem.
The content of the invention
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of organic glass for being capable of Uniform Tension
Glass blows drawing thermal forming device.
To achieve the above objectives, the technical scheme that the utility model is taken is：
A kind of lucite blows drawing thermal forming device, including vertical fuselage, and fuselage is provided with four vertical guide pillars, in fuselage
Upper die and lower die are installed, the corner of upper mould is connected to four guide pillars respectively, and upper mould is slided up and down by upper cylinder half drives edge guide pillar, under
Mould bottom is provided with vertical master cylinder, and lower mould moves up and down under master cylinder promotion, and upper mould is provided with the hemisphere die cavity of depression directed downwardly
Body, lower mould be with hemispherical cavity to hemisphere, hemisphere face cavity is formed during upper and lower mould matched moulds, it is characterised in that up and down
Intermode is provided with the workbench for being fixed on fuselage, and the center of workbench is provided with seal sleeve, and seal sleeve is passed through in workbench
The heart, the top of seal sleeve is flange face, and flange face is fixedly connected with the top surface of workbench, and lower mould is arranged in seal sleeve simultaneously
In oscilaltion；Seal sleeve open top, the bottom surface of seal sleeve and the projecting shaft of master cylinder are slidingly sealed, the seal sleeve
Side wall on be respectively equipped with air inlet and air bleeding valve.
Further, the bottom surface of the upper mould be provided with seal sleeve flange face for sealing ring.
After taking above technical scheme, the beneficial effects of the utility model I be：This equipment is combined using stretching and blowing
Mode, the lucite of heating and softening is placed on workbench, upper mould is descending and pushes down lucite, now plexiglass cover
Firmly seal sleeve forms sealing, first has and is pushed up on lower mould, hemispherical cover body is formed, during being pushed up on lower mould, among lucite
Part stretches more, expects that thick relative surrounding is thin, and behind upper top to certain position, lower mould stops, seal sleeve injection gases at high pressure,
Gas props up half-formed cover body and continues to stretch, and now lucite surrounding starts to expand, and material is thick thinning, and to ball-type
Change.Material stretching is uniform, until lucite touches the inner chamber of mould, lower mould continues upper top, stopped after reaching predetermined altitude
Only extruding lucite has been molded with uniform thin and thick, now lucite again.Air bleeding valve is opened, is taken off after lucite air cooling
Mould completes processing.
Die drawn is combined by the technical program with blowing, is ensured the uniform stabilization of wall thickness by three sections of processes, is
The shaping of product disposable thermal, and do not limited by sheet metal thickness, output product dimensionally stable, thickness is uniform, intensity is high.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Embodiment
Specific embodiment of the present utility model is further described below in conjunction with accompanying drawing：
As illustrated, a kind of lucite blows drawing thermal forming device, including vertical fuselage 1, fuselage 1 is provided with four vertically
Guide pillar 2, mould 3 and lower mould 4 are installed in fuselage, the corner of upper mould 3 is connected to four guide pillars 2 respectively, and upper mould 3 is driven by upper cylinder half 5
Dynamic to be slided up and down along guide pillar 2, the lower bottom of mould 4 is provided with vertical master cylinder 6, and lower mould 4 moves up and down under the promotion of master cylinder 6, upper mould 3
Hemisphere cavity 7 provided with depression directed downwardly, lower mould 4 be with hemispherical cavity 7 to hemisphere, shape during upper and lower mould matched moulds
Into hemisphere face clip cavity body, upper and lower intermode is provided with the workbench 8 for being fixed on fuselage 1, and the center of workbench 8 is provided with seal sleeve
9, seal sleeve 9 passes through the center of workbench 8, and the top of seal sleeve 9 is the top of flange face 10, flange face 10 and workbench 8
Face is fixedly connected, the bottom surface of upper mould 3 be provided with the flange face of seal sleeve 9 for sealing ring 13.Lower mould 4 is arranged on sealing shroud
In cylinder 9 and in interior oscilaltion；The open top of seal sleeve 9,9 bottom surfaces of seal sleeve and the projecting shaft of master cylinder 6 have slip close
