Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Embodiment one
As shown in Figure 1,2,3, 4, the mold 100 for being used to make predeformation plastic-sucking tray structure of the present embodiment, the mould
Tool includes support frame 1, mold core 2, die ontology 3, be set to water inlet pipe 4 on the die ontology, outlet pipe 5, vacuum chamber,
Vacuum connection tube 6；Water inlet pipe, outlet pipe are connected to by water pump with external water source, and support frame as described above supports the die ontology, institute
The upper end that mold core is set to the die ontology is stated, cooling water pipe is equipped in the die ontology, the cooling water pipe is connected to institute
Water inlet pipe, outlet pipe progress water circulating cooling are stated, for the vacuum connection tube for connecting vacuum pump, the mold core includes mould
Core skeleton frame 7, the mold core ontology 8 with tray shape, mold core skeleton frame 7 are concordant with the upper end of die ontology 3.In the mold core ontology
Portion is in protuberance state, then constantly extends from middle part toward surrounding and drops, several aspirating holes 9, institute are evenly equipped on the mold core ontology
It states aspirating hole to be connected to the vacuum chamber, the vacuum chamber is connected to the vacuum connection tube.
The angle a of the upper surface B 11 of upper surface A10 and mold core ontology surrounding in the middle part of the mold core ontology are 2~3 °.
There is big square shape raised line 12, the big square shape raised line circumferentially-spaced is provided with stair shape raised line 13 in the middle part of the mold core ontology
With X font raised line 14, the stair shape raised line and X font raised line are connected separately with small openning shape raised line 15 and half square shape raised line
16.The mold core is made of aluminum material.Support frame as described above is I-shaped shape, is convenient for being connected in mold slots in this way.
The plastic suction forming apparatus of the prior art includes the mold slots equipped with T-shaped slot, and turntable rack is set in turntable rack
Plastic sheet material conveying device, heating furnace device.The mold 100 of the utility model is fixed in mold slots.Plastics sucking moulding
When in use, plastic sheet (usually 2-6mm is thick) is placed in advance in job position, plastic sheet material conveying device to machine by staff
(conveying device includes elevating mechanism, and elevating mechanism connects a surface plate, and surface plate is surrounded by pressure rack, and pressure rack includes clamping piece
And cylinder) descend through pressure rack sheet material is clamped and risen；The rotation of turntable rack, plastic sheet is sent into heating furnace device
Plastic sheet is heated and softened；At this point, automatic infrared temperature measurer is started to work, when plastic sheet reaches forming temperature,
The rotation of turntable rack, the plastic sheet after softening are sent to mold relative position, under plastic sheet material conveying device after general who has surrendered's softening
Plastic sheet is pressed on the mold core of mold, and vacuum pump generates negative pressure and plastic sheet is further adsorbed onto mould at the same time
Plastics sucking moulding on the surface of core, is transformed into support holder structure through cooling and shaping；Plastic sheet material conveying device rises, and takes from mold
Walk support holder structure, the rotation of turntable rack, plastic sheet material conveying device decline, clamping of the pressure rack release to support holder structure product, work
Support holder structure product is taken away as personnel.
Embodiment two
As shown in Figure 3,4, the present embodiment two is basically the same as the first embodiment, the difference is that mould described in the present embodiment
Core 2 is made of thermosetting phenolic resin material.It is yellow, transparent, amorphous bulk that the phenolic resin, which is solid phenolic resin,
Substance be in blush because containing free phenol, and the specific gravity of entity is averaged 1.7 or so, is soluble in alcohol, not soluble in water, to water, weak
Acid, weak caustic solution are stablized.Phenol and formaldehyde under catalysts conditions polycondensation, it is neutralized, washing and made of resin.Because selecting
The difference of catalyst can be divided into two class of thermosetting property and thermoplasticity.Phenolic resin has good acid resistance, mechanical property, resistance to
Hot property is widely used in the industries such as anticorrosion engineering, adhesive, fire proofing, grinding wheel manufacture.Since mold core uses phenolic aldehyde
Resin material production, and support holder structure product and mold core are all plastic materials, have the function of lubrication, institute between plastics and plastics
In support holder structure formed product, greatly to avoid support holder structure product adhesion on mold core, the significant increase matter of product
Amount and production efficiency.
The utility model structure is simple, at low cost；And it can be to front in grand in the middle part of the support holder structure product made
The state of rising, i.e. support holder structure product first take predeformation measure, shrink rear tray structure in the stress of support holder structure product and produce
Product will restore automatically to formation state, ensure the quality of support holder structure product, meet the requirement of user；Additionally, due to
Mold core is made of phenolic resin material, in support holder structure formed product, avoids support holder structure product adhesion on mold core,
The significant increase quality and production efficiency of product.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
