Abstract
The utility model provides a compound co - extruded profiles's of unplasticized poly(vinyl chloride) and silicon rubber crowded mould altogether for door and window, be used for the extrusion molding with the fashioned sealed with silicone rubber strip of section bar integration includes the filling mould main part that is formed by left splint and right splintage combination, sets up the electrical heating board in the left splint and the right splint outside respectively, the one end that filling mould main part and extruder link to each other is opened there is the feed inlet, and it has inside runner and PVC section bar filling groove to communicate in proper order in the feed inlet, PVC section bar filling groove includes the filling groove notch with the compound co - extruded profiles's of silicon rubber install groove shape looks adaptation with unplasticized poly(vinyl chloride) for the door and window, is located the first seal groove that filling groove notch lower extreme just closes on inside runner, is located the second seal groove that inside runner was just kept away from to filling groove notch lower extreme, first seal groove and second seal groove pass through the runner intercommunication, the utility model discloses the mould solves that the easy shrink in the use of traditional sealing material shortens, turn -up and bent wrinkle, form sealed breach scheduling problem.
Description
Technical field
The utility model belongs to not plasticized polyvinyl chloride section bar field, is specifically related to the co-extruding mould of a kind of door and window not plasticized polyvinyl chloride and silicon rubber composite coextrusion section.
Background technology
Since using plastic door-window around nineteen sixty, polyvinyl chloride (PVC-U) door and window obtains the whole world and approves widely and use.Polyvinyl chloride (PVC-U) door and window of inexpensive, energy-saving and environmental protection, becomes the first-selection of China's Green energy-saving buildings undoubtedly.
In the manufacturing process of plastic door-window, reaching except energy-conservation and requirement of strength, inexpensive section bar except using, also needing to use the auxiliary material such as lockset, five metals, glass, encapsulant, just can complete the processing and making process of door and window.
Traditional encapsulant is the rubber weather strip adopting one-shot forming technique, complete separately at rubber molding plant, by traditional rubber extruding technique, produce the rubber adhesive tape that shape meets door and window instructions for use, after being purchased by door and window processing enterprise, by workman adhesive tape embedded in the polychloroethylene section bar simultaneously bought in processing factory.But due to larger contractility and the frictional force of adhesive tape, make adhesive tape and section bar adhesion in the longitudinal direction uneven, cause easily shrink shorten, crimping and bent wrinkle, affect sealing effectiveness, and production efficiency is also lower.
So plastic irregular profile sealing material Problems existing is urgently to be resolved hurrily.
Summary of the invention
For solving section bar in processing use procedure, encapsulant Problems existing, the purpose of this utility model is the co-extruding mould providing a kind of door and window not plasticized polyvinyl chloride and silicon rubber composite coextrusion section, the utility model mould solves the technical barrier of the macromolecular material co-extrusion of different qualities, solves conventional sealing material simultaneously and in use easily shrinks and shorten, crimping and bent wrinkle, form the problems such as seal gap.
To achieve these goals, the present invention is by the following technical solutions:
The co-extruding mould of a kind of door and window not plasticized polyvinyl chloride and silicon rubber composite coextrusion section, for the silastic sealing strip of extrusion molding and described section bar integrated molding, comprise the filling die main body formed by left clamping plate 1 and right clamping plate 2 fixed Combination, be separately positioned on the electric boiling plate 3 outside left clamping plate 1 and right clamping plate 2; One end that described filling die main body is connected with extruder has charging aperture 4, inner flow passage 5 and the filling groove 6 of PVC profile is communicated with successively in charging aperture 4, the filling groove of described PVC profile 6 comprises the filling groove notch 6-1 suitable with the mounting groove mouth-shaped of door and window not plasticized polyvinyl chloride and silicon rubber composite coextrusion section 7, be positioned at filling groove notch 6-1 lower end and close on the first seal groove 6-2 of inner flow passage 5, be positioned at filling groove notch 6-1 lower end and away from the second seal groove 6-3 of inner flow passage 5, described first seal groove 6-2 and the second seal groove 6-3 passes through flow passage.
Compared to the prior art comparatively, the utility model tool has the following advantages:
By the utility model mould by rubber and plastic extruder and the door and window combination of not plasticized polyvinyl chloride product production line, realize composite co-extruding, one-shot forming.Methyl vinyl silicone rubber and not plasticized polyvinyl chloride product forms are formed one, in use easily shrink and shorten to solve conventional sealing material, crimping and bent wrinkle, form the problems such as seal gap.

Detailed description of the invention
As depicted in figs. 1 and 2, the co-extruding mould of a kind of door and window not plasticized polyvinyl chloride of the utility model and silicon rubber composite coextrusion section, for the silastic sealing strip of extrusion molding and described section bar integrated molding, comprise the filling die main body formed by left clamping plate 1 and right clamping plate 2 fixed Combination, be separately positioned on the electric boiling plate 3 outside left clamping plate 1 and right clamping plate 2, for PVC profile by preheating object during mould, and to silicon rubber heating material, softening, ensure the mobility of material; One end that described filling die main body is connected with extruder has charging aperture 4, inner flow passage 5 and the filling groove 6 of PVC profile is communicated with successively in charging aperture 4, the filling groove of described PVC profile 6 comprises the filling groove notch 6-1 suitable with the mounting groove mouth-shaped of door and window not plasticized polyvinyl chloride and silicon rubber composite coextrusion section, be positioned at filling groove notch 6-1 lower end and close on the first seal groove 6-2 of inner flow passage 5, be positioned at filling groove notch 6-1 lower end and away from the second seal groove 6-3 of inner flow passage 5, described first seal groove 6-2 and the second seal groove 6-3 passes through flow passage.
As shown in Figure 3, operation principle of the present utility model is: the methyl vinyl silicone rubber particle crossed through maturation process, through the heating of rubber and plastic extruder, extrude, enter in filling die main body by charging aperture 4, the filling groove 6 of PVC profile is arrived by inner flow passage 5, wherein a part first arrives 1 first seal groove 6-2, enters the second seal groove 6-3 through inner flow passage, bonding at PVC profile filling groove 6 place with the PVC profile 7 through cooling and shaping.Make the silastic sealing strip shown in the shaping rear formation Fig. 4 of methyl vinyl silicone rubber.Make silastic sealing strip completely by designing requirement filling in PVC profile in the filling groove reserved, finally form door and window not plasticized polyvinyl chloride (PVC-U) of the present invention and silicon rubber composite coextrusion section product.
As shown in Figure 4, the silastic sealing strip of formation, by filling foundation 8, seals 9 and second with first of filling foundation 8 integrated molding and seals 10 and form.
