Description
Technical field
The present invention relates 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 are formed.Its product has that bending strength is big, shock resistance is good, light transmission is good, chemically stable
Property is good, good weatherability the advantages of.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 current hemispherical lucite 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
To overcome the deficiencies in the prior art, blown it is an object of the invention to provide a kind of lucite for being capable of Uniform Tension
Draw thermal forming device.
To achieve the above objectives, the technical scheme taken of the present invention is：
A kind of lucite blows drawing thermal forming device, including vertical fuselage, and fuselage is provided with four vertical guide pillars, and fuselage is interior to be installed
There are upper die and lower die, 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, lower mould bottom
Portion is provided with vertical master cylinder, and lower mould is moved up and down under master cylinder promotion, and upper mould is provided with the hemisphere cavity of depression directed downwardly, under
Mould be with hemispherical cavity to hemisphere, hemisphere face cavity is formed during upper and lower mould matched moulds, it is characterised in that intermode up and down
Provided with the workbench for being fixed on fuselage, the center of workbench is provided with seal sleeve, and seal sleeve passes through the center of workbench, close
The top of big envelope cylinder is flange face, and flange face is fixedly connected with the top surface of workbench, and lower mould is arranged in seal sleeve and upper
Lower lifting；Seal sleeve open top, the bottom surface of seal sleeve and the projecting shaft of master cylinder are slidingly sealed, the side of the seal sleeve
Air inlet and air bleeding valve are respectively equipped with wall.
Further, the bottom surface of the upper mould be provided with seal sleeve flange face for sealing ring.
Take after above technical scheme, beneficial effects of the present invention I be：The side that this equipment is combined using stretching with blowing
Formula, is placed on workbench, upper mould is descending and pushes down lucite, and now lucite covers close by the lucite of heating and softening
Big envelope cylinder forms sealing, first has and is pushed up on lower mould, is formed during being pushed up on hemispherical cover body, lower mould, lucite center section
Stretching is more, and the thick relative surrounding of material is thin, and behind upper top to certain position, lower mould stops, seal sleeve injection gases at high pressure, gas
Prop up half-formed cover body and continue stretching, now lucite surrounding starts expansion, and material is thick thinning, and become to ball-typeization
Change.Material stretching is uniform, is pushed up until lucite is touched in the inner chamber of mould, lower mould continuation, reaches and stop after predetermined altitude
Extruding lucite has been molded with uniform thin and thick, now lucite again.Open and be stripped after air bleeding valve, lucite air cooling
Complete 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 are uniform, intensity is high.
Brief description of the drawings
Fig. 1 is front view of the invention.
Embodiment
The embodiment of the present invention 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 vertical guide pillars
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 by the drives edge of upper cylinder half 5
Guide pillar 2 is slided up and down, and the lower bottom of mould 4 is provided with vertical master cylinder 6, and lower mould 4 is moved up and down under the promotion of master cylinder 6, and upper mould 3 is provided with
The hemisphere cavity 7 of depression directed downwardly, lower mould 4 is the hemisphere with 7 pairs of hemispherical cavity, and half is formed during upper and lower mould matched moulds
Sphere presss from both sides cavity, and 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, close
Big envelope cylinder 9 passes through the center of workbench 8, and the top of seal sleeve 9 is flange face 10, and the top surface of flange face 10 and workbench 8 is consolidated
Fixed connection, 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 seal sleeve 9
