The invention is characterized in that: a, the co-extrusion mould is provided with a small diamond, wherein, the top of the small diamond is provided with the co-extrusion boss and a forming channel, and the small diamond is connected with the left co-extrusion template as a whole; b, a core rod is hung in the performing channel and the forming channel, the core rod is provided with an axial cold air channel, one end of the core rod is inserted in the right co-extrusion template, and the right co-extrusion template is provided with an air feed channel which is communicated with the cold air channel. The invention has the advantages of producing and maintaining conveniently, saving replacing cost and the like. According to the invention, the O-shaped sealing joint strip and the plastic door and window profile shapes can be co-extruded for molding.
Description
(1) technical field: the present invention relates to the plastic door and windows profile processing mold, especially a kind ofly maintain easily co-extruding mould after the totally-enclosed embedded O type adhesive tape.
The (2) background technology: modern society improves the sealing requirements of door and window, and the pattern of sealing joint strip also becomes development in pluralism, but the sealing of the plastic door-window on the market relies on frame, fan, glass, rubber adhesive tape to realize mostly.Adhesive tape combines with door and window profile material; Normally when door and window is made, K type adhesive tape is embedded in the T-slot of profile shapes with instrument by manual work, but because the big contractility and the frictional force of adhesive tape; Cause adhesive tape and section bar adhesion in the longitudinal direction inhomogeneous; Easy contraction shortens, crimping or bent wrinkle, influence sealing effectiveness, and production efficiency is also lower.
Co-extruding mould after a kind of K type adhesive tape of the plastic door and windows profile that is referred to as welded type is arranged at present; Mainly be by the adhesive tape mould and be fixed on its outside electric boiling plate that insert the compositions such as thermocouple of mold, it is after the profile shapes fused materials is by the moulding of extruder die head; Through doing typing, wet setting, will getting into before hauling machine, fixed length cutting, the packing; Once more the binding site of profile shapes and adhesive tape is heated to little state that melts with electric heater, the adhesive tape material of fusion is extruded on the T-slot edge of profile shapes through the back co-extruding mould by co-extrusion machine, make its bonding mould; Its structure is: it has left and right sides co-extrusion template; Two co-extrusion templates splicing one, the tip designs of two co-extrusion templates has the co-extrusion boss, and the outside of two co-extrusion templates is equipped with left and right sides electric boiling plate and is inserted the left and right sides thermocouple of two electric boiling plates; In the co-extrusion template of right side, have feed channel; In the co-extrusion template of left side, have supply channel and be communicated with feed channel, co-extrusion template top bit offers preforming material road and final shaping unit material road below the co-extrusion boss in the left side, and the preforming material road is communicated with supply channel.Coextruding die after this K type adhesive tape because final shaping unit material road and preforming material road design on same co-extrusion template, expects that the road is very dark, makes difficulty, and cleaning, modification, maintenance are very inconvenient.Particularly in mould used, final shaping unit material road is often wearing and tearing in advance partly, in case the wearing and tearing of final shaping unit material road will be changed monoblock co-extrusion template like this, cause waste very big, and the enterprise production cost is increased.On the other hand; Co-extruding mould receives structural limitations after the K type adhesive tape, can only carry out the coextrusion mold processing of K type adhesive tape and plastic door and windows profile, and the bonding intensity of K type adhesive tape and profile shapes is difficult for guaranteeing; And technique controlling difficulty is big, and is high to the requirement of adhesive tape material adhesive property.
The (3) summary of the invention: the object of the invention is exactly will solve the coextrusion mold that co-extruding mould after the existing adhesive tape can only carry out K type adhesive tape and plastic door and windows profile to process; And the bonding intensity of K type adhesive tape and profile shapes is difficult for guaranteeing; And easy contraction distortion influences sealing effectiveness, and mould is made difficulty; Clear up, revise, safeguard problems such as inconvenience, a kind of co-extruding mould after the totally-enclosed embedded O type adhesive tape that maintains easily is provided.
Concrete scheme of the present invention is: a kind ofly maintain easily co-extruding mould after the totally-enclosed embedded O type adhesive tape; Has left and right sides co-extrusion template; Two co-extrusion templates splicing one, the tip designs of two co-extrusion templates has the co-extrusion boss, and the outside of two co-extrusion templates is equipped with left and right sides electric boiling plate and is inserted the left and right sides thermocouple of two electric boiling plates; In the co-extrusion template of right side, have feed channel; In the co-extrusion template of left side, have supply channel and be communicated with feed channel, co-extrusion template top bit offers preforming material road connection supply channel below the co-extrusion boss in the left side, and it is characterized in that: a. is designed with a blockage; The tip designs of blockage has the co-extrusion boss; The below that the top of blockage is positioned at the co-extrusion boss has final shaping unit material road, and blockage adopts bolt and left side co-extrusion template to fuse, and the co-extrusion boss on the blockage distinguished for one, one corresponding the connection with final shaping unit material road with co-extrusion boss and preforming material road on the co-extrusion template of left side; B. hang in the final shaping unit material road of preforming material road on the co-extrusion template of left side and blockage plug is housed; Have axial cold air road in the plug; One end of plug is inserted on the co-extrusion template of right side, and on the co-extrusion template of right side, has the cold air road that air supply duct is communicated with plug.
The thickness of blockage described in the present invention is 2/3～1 of left side coextruding die plate thickness.
Spacing equals the moulding wall thickness of O type adhesive tape between the inwall in outer wall of plug described in the present invention and preforming material road or final shaping unit material road.
The present invention compared with prior art has the following advantages:
Because " O " type sealing joint strip top that goes out with this Mold Making is directly embedded in the T type groove of profile shapes, so to the cementability no requirement (NR) of adhesive tape material, and section bar combines evenly, reliable and stable with adhesive tape, can not produce contraction, crimping or song and wrinkle etc.; And do not need electricity consumption hot blast pre-blowing section bar, saved expensive rapid wear electric heating wind element,, reduce cost so can save electric energy; Be designed with a cold air road in its deuterzooid mold core rod, be blown into cold wind specially, so the adhesive tape extrusion temperature is low, product deformation is little, is difficult for decomposing; Expressing technique is controlled easily, and is simple to operate, easy to maintenance.
The present invention simultaneously since with the design of final shaping unit material road at one independently on the blockage; Again blockage and left side co-extrusion template plate dress are one; Form a kind of composed structure mode, it is obvious that: the manufacturing of mould, maintenance, modification, cleaning are with very convenient; In case final shaping unit material road wearing and tearing in using simultaneously only need to change blockage and can continue to use, and have just reduced the production cost of producer so virtually.
