Description
Technical field
The present invention relates to a kind of foaming molding mold of thermoplastic expanded plastic pellet, especially relate to a kind of foaming molding mold of efficient energy-saving.
Background technology
With the styrofoam is the expandable thermoplastic particle of the in-molded foaming of the thermoplastic expanded plastics of being applied in of representative, after it is pre-expanded to desired expansion ratio earlier, again this thermoplastic molding's foamed plastic particle is imported in the mould, import the softening expansion second time of foaming of Steam Heating subsequently, treat the foaming of this prefoam thermoplastic particle melting be full of whole forming room after, then cool off entire die, after but product temperature to be formed is reduced to calcining temperature, the method of desirable foam molded product is taken out in the demoulding, is exactly the thermoplastic expanded plastic foamed moulding that generally is commonly called as.
The used foaming mould of above moulding process comprises parts such as die, punch.Die is fixed on above the fixed form of foaming machine, the another side punch is fixed on the moving die plate of foaming machine, punch is along with the hydraulic push rod drive shifting formwork base plate of make-up machine moves together, during the moulding foaming, die and punch combine, die core and punch core are entrenched togather mutually, form the forming cavity of a hollow, and thermoplastic expanded then plastic pellet is filled in this forming cavity by spray gun.The rear side of die core and punch core just is designed to vaporium separately, and vaporium is made up of separately framed, separately core installing plate and backboard separately.Design has separately steam inflow opening and cooling water inlet on the vaporium, and cooling water inlet is provided with cooling water inlet pipe in vaporium, the cooling water distribution tubule of dendritic numerous extensions also is set on the cooling water inlet pipe, cooling water distribution tubule distributes at interval uniformly, and, the end of cooling water distribution tubule also is provided with water-cooling-sprayer, in order to the cooling water atomized spray to the core of facing separately.Below vaporium, design has floss hole, core is provided with and prevents that foaming and intumescing from causing some of the fore-sets of core distortion separately, and die and being provided with imports thermoplasticity expandable plastic particle that spray gun in the forming cavity is some to be only reached assistance and will cool off some of the push rods that the moulding product of finalizing the design the back eject forming cavity.
In the foaming molding mold of above-mentioned matched moulds, thermoplastic expanded particle is injected in the forming cavity via spray gun, steam imports in the vaporium via steam inflow opening then, flow in the forming cavity via the core that gathers on the core again, thermoplastic expanded plastic pellet is heated to the softening expansion fusion of particle, be full of in the whole forming cavity, form desired formed body shape.Then cooling water inlet pipe imports cooling water, evenly is sprayed at the back side of core via shower nozzle, and the formed body in the forming cavity is cooled off.If be necessary, also mould can be vacuumized decompression evaporation and quicken cooling.After cooling finished, die and punch die sinking separated, with desired formed body by taking out in the mould.
But, in above-mentioned described moulding process, be directed to the steam in the foaming mould, in with the thermoplastic expanded plastic pellet heating in the forming cavity, also heat entire die simultaneously, that is to say, form the core of vaporium, and backboard framed, that core installing plate separately reaches separately separately also has been heated by steam simultaneously.Then, formed body in the forming cavity is when being used water quench by the shower nozzle in the vaporium, core and framed and core installing plate separately separately and backboard separately also have been cooled simultaneously, and be heated in the member of cooling at these, except core, all the quality with formed body does not have important direct relation.
So in heat temperature raising and the repeatable operation process that cools, most of heat energy of steam has just been consumed as the useless energy.So, produce the steam that thermoplastic expanded plastic shaped body consumes, having only very little part is that actual use is on heating products, most steam just is consumed in meaningless heating mould by aforesaid, steam, cooling, drainage piping, the mode with hot water has slatterned via floss hole then; And, these moulds, but the heats cold of steam, cooling, drainage piping needs the consumption plenty of time, has caused the elongation of molding time indirectly, and production efficiency reduces.So this is a big problem that exists in the production technology of thermoplastic expanded plastic shaped body.
Therefore, the researcher carries out years of researches to this problem, mainly contains following so several settling mode:
1, early stage settling mode is, to the irrelevant vaporium inner face of foam molded product quality, utilize the rubber line with rubber construction about 3～9mm, improve thermal insulation, reduce the meaningless energy waste that heating and cooling caused.And rubber lined material, again with relatively cheap, easily the butyl rubber (IIR) of processing is main.But, the shortcoming of this mode is: the maximum operation (service) temperature of butyl rubber is about 100～120 ℃, and be example with the eps expanded polystyrene (EPS), the needed steam maximum temperature of its moulding is about 110 ℃, soon near the serviceability temperature upper limit of butyl rubber, the cooling of heating repeatedly through after a while inevitably can occur wearing out the phenomenon of peeling off.And at foaming melt temperature higher expanded material, expanded polypropylene (EPP) for example, the vapor (steam) temperature of its fusion is 150 ℃ of front and back, the upper limit considerably beyond the butyl rubber serviceability temperature, the result causes butyl rubber lining thermal insulation layer aging more ahead of time, peels off, and effect of heat insulation significantly reduces.Can be blocked in the floss hole and peel off the butyl rubber that comes off, perhaps the butyl rubber of aging efflorescence can be blocked on the core of core, perhaps along with steam is attached on the surface of white moulding product, causes moulding product quality to reduce.These all are to have the insoluble for a long time difficult point of industry.In addition, rubber lining is a technology that needs the professional, and the construction cost height causes the cost of foaming mould rubber lining thermal insulation layer high, adds easily aging shortcoming, uses not general.So industry is being sought low cost always, easily construction, the new solution that the life-span is long.
2, the anti-spraying barrier plate is set between vaporium entodorsum and cooling water pipe, prevents that the cooling water splash is to backboard.But, the shortcoming of this method is to reduce the steam loss DeGrain, and splash guard is set needs additional space, if use on ready-made mould, the distance that will cause spraying water shortens, and cooling effect reduces, if die sinking again, cause cost significantly to rise again, in addition, splash guard also need the to heat up circulation of cooling itself also needs to consume steam.
3, in order to reduce difficulty of construction and to increase the life-span, adopt the solution of silicone-coating insulating moulding coating.But, because the hot line expansion rate of metal material is 10 * 10
-6/ ℃～30 * 10
-6/ ℃, but the hot line expansion rate of this heat-barrier material is less than 10 * 10
-6/ ℃, exist coating different with the thermal coefficient of expansion of mould base material, cause when cooling heating, because the difference of degrees of expansion, caused heat insulating coat and peeling off of base material and come off, reduced effect of heat insulation.Also have, in order to increase effect of heat insulation, coating needs thickening, but the coating thickening causes cracking again easily, causes and peels off.And the material cost height of silicones own, if the production number of times of mould is very few, will faces cost and reclaim as yet, finish to cause the shortcoming of losing money die life.
Summary of the invention
The objective of the invention is: a kind of foaming molding mold of efficient energy-saving is provided, its simple in structure, easy construction, cost is low; Life-span is long, and is stable and reliable for performance; Can effectively reduce steam consumption, save steam thermal energy, and improve production efficient, be beneficial to popularization.
Technical scheme of the present invention is: a kind of foaming molding mold of efficient energy-saving, comprise die, punch, die inside is provided with vaporium, vaporium by die core, framed, installing plate, backboard is enclosed constitutes, punch inside is provided with vaporium, vaporium by punch core, framed, installing plate, backboard is enclosed constitutes, framed, the installing plate of described die, at least a portion on the surface of vaporium of backboard or all be provided with hexsteel; Framed, the installing plate of described punch, at least a portion on the surface of vaporium of backboard or all be provided with hexsteel; Described hexsteel outside is coated with thermal insulation layer.
