Abstract
A kind of minimizing plastic irregular profile color coextrusion surface tear device, comprise stock mould and cover plate thereof, die cavity is provided with in stock mould, the chamber wall of this die cavity is provided with multiple vacuum buffer groove, described each vacuum buffer groove is all communicated with die cavity, and the intersection of vacuum buffer groove and die cavity is all rounded down, vacuum buffer groove is also communicated with the vacuum room be arranged in cover plate by the exhaust passage be arranged in stock mould, the bleeding point place of vacuum room is connected with vacuum adapter, and each vacuum adapter is provided with the control valve for regulating vacuum room's internal vacuum size; The utility model can not only effectively regulate vacuum to avoid colored material to be adsorbed in vacuum buffer groove, and by effectively prevent the scuffing on plastic irregular profile color coextrusion surface to the setting of vacuum buffer groove rounding, greatly improve the qualification rate of product forms, thus save the resources costs of raw material, artificial each side, enhance productivity.
Description
Technical field
The utility model relates to plastic extrusion production equipment field, relates to a kind of minimizing plastic irregular profile color coextrusion surface tear device specifically.
Background technology
On the setting mould of colour section bar extrusion die first paragraph co-extrusion coloured surface, because the type embryo extruded remains viscous state, be easy to be attracted in vacuum buffer groove under the effect that vacuum is larger, existing mould vacuum buffer trough rim is wedge angle, colored Surface of profile is scratched by the surface of direct effect to colour section bar of corner after sucking the corner of vacuum buffer groove, affects the qualification rate of section bar surface quality and shape product.
Utility model content
The utility model is in order to solve technique scheme, there is provided a kind of and reduce plastic irregular profile color coextrusion surface tear device, it can not only effectively regulate vacuum to avoid colored material to be adsorbed in vacuum buffer groove, and by effectively prevent the scuffing on plastic irregular profile color coextrusion surface to the setting of vacuum buffer groove rounding, greatly improve the qualification rate of product forms, thus save the resources costs of raw material, artificial each side, enhance productivity.
The technical solution adopted in the utility model is: a kind of minimizing plastic irregular profile color coextrusion surface tear device, comprise stock mould and cover plate thereof, die cavity is provided with in described stock mould, the chamber wall of this die cavity is provided with multiple vacuum buffer groove, described each vacuum buffer groove is all communicated with die cavity, and the intersection of vacuum buffer groove and die cavity is all rounded down, this vacuum buffer groove is also communicated with the vacuum room be arranged in cover plate by the exhaust passage be arranged in stock mould, the bleeding point place of vacuum room is connected with vacuum adapter, each vacuum adapter is provided with the control valve for regulating vacuum room's internal vacuum size.
Diaphragm seal is provided with between described vacuum adapter and bleeding point.
Described vacuum adapter is connected with frequency conversion vavuum pump.
The beneficial effects of the utility model: the interface place of the utility model vacuum buffer groove and die cavity is rounded down, effectively prevent vacuum buffer rooved face and directly scratch coloured surface; Being provided with the control valve for regulating vacuum size in the utility model, effectively avoiding crossing ambassador's colour because of vacuum and expecting that being adsorbed onto vacuum buffer groove face inside causes scratch, improves the qualification rate of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1, stock mould, 2, cover plate, 3, vacuum buffer groove, 4, exhaust passage, 5, vacuum room, 6, vacuum adapter, 7, control valve.
Detailed description of the invention
As shown in the figure, a kind of minimizing plastic irregular profile color coextrusion surface tear device, comprise stock mould 1 and cover plate 2 thereof, die cavity is provided with in described stock mould 1, the chamber wall of this die cavity is provided with multiple vacuum buffer groove 3, each vacuum buffer groove 3 is all communicated with die cavity, wherein, each vacuum buffer groove 3 is all rounded down with the intersection of die cavity the scuffing avoiding color coextrusion surface, and vacuum buffer groove 3 is communicated with the vacuum room 5 be arranged in cover plate 2 by exhaust passage 4, described exhaust passage 4 is arranged in stock mould 1, the bleeding point place of vacuum room 5 is connected with vacuum adapter 6, vacuum adapter 6 is connected with frequency conversion vavuum pump, and be provided with diaphragm seal between vacuum adapter 6 and bleeding point, each vacuum adapter 6 is provided with the control valve 7 for regulating vacuum room 5 and vacuum buffer groove 3 internal vacuum size, to avoid because vacuum is excessive, color coextrusion surface is because expecting that soft being adsorbed in vacuum buffer groove 3 causes surface tear.
The interface place of the utility model vacuum buffer groove and die cavity is rounded down, and effectively prevent vacuum buffer rooved face and directly scratches coloured surface; Being provided with the control valve for regulating vacuum size in the utility model, effectively avoiding crossing ambassador's colour because of vacuum and expecting that being adsorbed onto vacuum buffer groove face inside causes scratch.
