Detailed description of the invention
The general eps foam mould of plastics 80 of a kind of steam, as shown in Figure 1 and Figure 2.Described mould 80 comprises that the patrix location-plate 5, the patrix that from top to bottom stack together successively are framed 4, lower mold core 2, framed 3, counterdie location-plate 1.Described framed 3 are enclosed within lower mold core 2.
As shown in figure 11, a steam vent 33 is provided with in the middle of described counterdie location-plate 1; Counterdie location-plate 1 is provided with two circle sealing slots 16;
As shown in Figures 9 and 10, the bottom surface of lower mold core 2 and sidewall are formed changes steam chest 10, and lower mold core 2 is arranged on above counterdie location-plate 1, and the sidewall of lower mold core 2 is embedded between two circle sealing slots 16 just, and conversion steam chest 10 communicates with steam vent 33; Sidewall is provided with carbonated drink through hole 25; Lower mold core 2 end face is provided with some core rod heads 23, is provided with ventilatory micropore 24 in the middle of core rod head 23, and ventilatory micropore 24 communicates with conversion steam chest 10.Be provided with carbonated drink runner between core rod head 23 and core rod head 23, carbonated drink runner communicates with described carbonated drink through hole 25; Core rod head 23 and carbonated drink runner are a disjunctor, when not arranging any O type packing ring, isolate with air water, so infiltrate products when cooling without any cooling water, therefore product surface is clean bright, smooth, be not polluted, really permanently effectively reach clean hygiene.In addition, when core rod cools, cooling water channel (carbonated drink runner) is arranged between core rod head 23, cooling water penetrates in cooling water channel, directly be connected with the external world, also cause the problems such as isolation is too large, too slow, the productivity ratio reduction of being heated without additional configuration separating plate, also not be used in steam passage two ends and all establish plug and plug screw to block.Ventilatory micropore 24 is vertical to be directly connected with conversion steam chest 10, and conversion steam chest 10 makes steam enter to be evenly distributed, and whole mould moisture isolates that effectively to improve frequent die change loaded down with trivial details.The steam time is grown and leads to shut up and gets rusty.Sealing slot 16 can also be provided with above sidewall.
As shown in FIG. 7 and 8, vertically run through and be provided with a ladder hole in the middle part of in the of framed 3, framed 3 are enclosed within lower mold core 2, and sidewall laterally runs through being provided with into water air intake 21, water inlet air intake 21 communicates with carbonated drink through hole 25.
As illustrated in Figures 5 and 6, patrix framed 4 is arranged on above in the of framed 3, and the bottom surface of patrix framed 4, sidewall and lower mold core 2 end face form die cavity; Die cavity communicates with ventilatory micropore 24; Framed 4 end faces of patrix are provided with stepped cylinder 18, and stepped cylinder 18 has the central through hole communicated with die cavity; The top of stepped cylinder 18 is provided with screw thread; On described sidewall, four drain outlets 22 and closed liquid bath 19, four drain outlets 22 communicate with liquid bath 19.
As shown in Figures 3 and 4, patrix location-plate 5 end face is provided with choked flow post 13, and when making the carbonated drink room between patrix framed 4 and patrix location-plate 5, carbonated drink velocity flow profile is even, is heated, cooling balance.
Center has charging aperture 17, stepped cylinder 18 is embedded in charging aperture 17, upper end is fixed by nut 6, make itself and patrix location-plate 5 stranded, sealing, prevents carbonated drink from flowing in product simultaneously, solves in existing mould, because the impulsive force of steam and water easily causes broken screw and silking to damage, carbonated drink is made to enter into the technical problem of products; Patrix location-plate 5 side is provided with two horizontal admission mouths of a river 11, and opposite side is provided with two horizontal delivery ports, 12, two horizontal admission mouths of a river 11 and two horizontal delivery ports 12 communicate with four drain outlets 22 respectively.The horizontal admission mouth of a river 11, compared to the admission mouth of a river of existing vertical direction, effectively can be reduced vapour with water to the impulsive force of mould, make its framed minimizing stress prolongation life cycle.Horizontal delivery port 12 makes water from bottom to top flow out from periphery, and extend the time of flowing in carbonated drink room, carbonated drink is evenly distributed, and raises the efficiency, and ensures product quality.
Described counterdie location-plate 1, framed 3, patrix are framed 4, patrix location-plate 5 is equipped with screw hole 15 and cover post holes 14, and alignment pin inserts in cover post holes 14, for accurate location; Stock screw inserts in screw hole 15, fixing counterdie location-plate 1, framed 3, patrix framed 4 and patrix location-plate 5.
During production, operating procedure following (in conjunction with Figure 12):
(1) insert in charging aperture 17 with special spray gun rifle head, utilize compressed air that the EPS bead foamed is injected die cavity;
(2) steam is injected from the water inlet air intake 21 on the horizontal admission mouth of a river 11, framed 3 patrix location-plate 5, wherein, the steam injected from the horizontal admission mouth of a river 11 refluxes at liquid bath 19, die cavity is heated, the steam injected from the water inlet air intake 21 framed 3 enters carbonated drink runner by carbonated drink through hole 25, heats lower mold core 2;
(3) inject steam from the steam vent 33 counterdie location-plate 1, steam flows into conversion steam chest 10, and enters die cavity by ventilatory micropore 24, makes it carry out thermoplastic to the EPS bead foamed;
(4), after sintering adhesion, inject cooling water from the water inlet air intake 21 on the horizontal admission mouth of a river 11, framed 3 patrix location-plate 5, mold cools down is made its formed product; Gas in the product simultaneously utilizing vacuum drawn machine to extract in die cavity from the steam vent 33 counterdie location-plate and moisture content.
(5) die sinking: utilize compressed air to inject air from charging aperture 17 and steam vent 33, the product of forming is departed from and blows out.
The above, the preferred embodiment of Gongwei's the utility model, therefore the scope that can not limit that the utility model implements according to this, the equivalence change namely done according to this utility patent scope and description with modify, all should still belong in scope that this practicality contains.
