Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
Embodiment one
As shown in Figure 1,2,3, 4, the mold 100 for making predeformation plastic-sucking tray structure of the present embodiment, the mould
Tool includes supporting rack 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 A10 and upper surface B 11 of mold core ontology surrounding in the middle part of the mold core ontology is 2~3 °.
There is big square shape raised line 12, the big square shape raised line circumferentially-spaced to be provided with stair shape raised line 13 in the middle part of the mold core ontology
With X fonts raised line 14, the stair shape raised line and X font raised lines 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 present invention is fixed in mold slots.Plastic suction forming apparatus exists
In use, plastic sheet (being usually 2-6mm thick) is placed in advance in job position by staff, plastic sheet material conveying device is (defeated
It includes elevating mechanism to send device, and elevating mechanism connects a surface plate, and surface plate is surrounded by pressure rack, pressure rack include clamping piece and
Cylinder) it descends through pressure rack sheet material is clamped and risen；Turntable rack rotates, and plastic sheet is sent into heating furnace device to modeling
Media sheet is heated and softened；At this point, automatic infrared temperature measurer is started to work, and when plastic sheet reaches forming temperature, turntable
Rack rotates, and the plastic sheet after softening is sent to mold relative position, the plastics under plastic sheet material conveying device after general who has surrendered's softening
Sheet material is pressed on the mold core of mold, and at the same time vacuum pump generates negative pressure and plastic sheet is further adsorbed onto mold core
Plastics sucking moulding on surface, is transformed into support holder structure through cooling and shaping；Plastic sheet material conveying device rises, and takes support away from mold
Dish structure, the rotation of turntable rack, plastic sheet material conveying device decline, and pressure rack unclamps the clamping to support holder structure product, and work people
Member takes support holder structure product away.
Embodiment two
As shown in Figure 3,4, the present embodiment two and embodiment one are essentially identical, 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 is in blush because containing free phenol, and the proportion of entity average 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 makes, and support holder structure product and mold core are all plastic materials, has 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 configuration of the present invention is simple, it is at low cost；And it can be to front in crowned in the middle part of the support holder structure product made
State, i.e. support holder structure product first take predeformation measure, shrink rear tray structure product just in the stress of support holder structure product
It can automatically restore to formation state, ensure the quality of support holder structure product, meet the requirement of user；Additionally, due to mold core
It is made of phenolic resin material, in support holder structure formed product, avoids support holder structure product adhesion on mold core, greatly
Improve the quality and production efficiency of product.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
