Abstract
The utility model provides a special clamp for welding an automobile glass edge covering strip and relates to a welding mould. The special clamp comprises a vertical clamping mould and a transverse clamping clamp, and is characterized in that each clamping mould is integrally provided with an upper mould core strip and a lower mould core strip; the outline shape of the section of the upper mould core strip is the same as that of the inner wall of an upper groove section of a curved-edge-shaped H-type edge covering strip; one end opening of the upper mould core strip is a 45-degree inclined cutting angle; the outline shape of the section of the lower mould core strip is the same as that of the inner wall of a lower groove section of the curved-edge-shaped H-type edge covering strip; the lower mould core strip is the 45-degree inclined cutting angle; in a welding process, the upper mould core strip and the lower mould core strip are respectively sleeved in upper and lower concave cavities of the edge covering strip; and an inclined cutting opening of the mould core strip is leveled with an inclined cutting opening of the edge covering strip. The special clamp has the advantages that in a welding process, the mould core strip rigidly supports the edge covering strip, so that the abutted matching degree is good, the precision is high and the deformation is not caused.
Description
Technical field:
The utility model relates to the melting welding mould, the special fixture of particularly a kind of automobile glass encapsulation bar welding.
Background technology:
The edge cover strip of vehicle glass PVC soft material is a kind of section bar of extrusion modling.Mostly the edge cover strip shape is abnormity, existing its bent limit of cross section type of being " H " font of a kind of edge cover strip, and cavity is the big shape chamber of little, the interior abdomen of opening of different sizes up and down.
Vehicle glass is rectangular-shaped, and then edge cover strip is a correspondingly-shaped, but extrudate is a strip, thereby can only cut into four edge strips.Each edge strip port is the miter angle of cutting sth. askew, and latter two adjacent edge strip two-port is implemented the butt joint thermofussion welding.Earlier one section side of two edges is clipped in respectively in vertical clamping that vertical each other port is 45 degree angles of chamfer, the horizontal clamping before the thermofussion welding.Each clamping by the following mould of symmetry and on turn over mould and form, both implement hinged respectively through fixing hinged hinge on it, the two interface is respectively arranged with trapezoidal rectangular positioning boss, the rectangular location cavity that disjunctor extends.The two interface is respectively arranged with strip half groove corresponding to the edge cover strip gabarit, and when the two matched moulds, the inner chamber behind the two and half groove matched moulds is corresponding with the edge cover strip gabarit.Butt joint is during melting welding, and two edge cover strips are enclosed within respectively in the vertical, horizontal mould on the sliding formwork frame, and cut sth. askew port and mould of two edge cover strips cut sth. askew after port aligns; Two mould slippages port of cutting sth. askew is fitted each other; It is motionless then to pin edge cover strip, will retreat 1-2mm respectively to mould in length and breadth, exposes the craft port of two edge cover strips; Then the melting welding head of fusing soldering welder stretches into the space that two moulds are sold, and edge cover strip is carried out thermofussion welding.After the thermofussion welding, the melting welding head withdraws from, and two mould slippages is fitted, to guarantee the hot gabarit down of the port butt joint typing of cutting sth. askew of two edge cover strips again.After treating two edge cover strip cooling curings, just open and turn over the edge cover strip that mould takes out the Corner butt joint of moulding.
The defective that this fusion welding method exists is: during two edge cover strip melting welding; Because the bent limit of edge cover strip be type " H " font, cavity about having, the port that yielding exposes 1-2mm are not had a rigidity; Be prone to produce distortion when the contact of melting welding head, heating; Equally also can be out of shape during cooling,, influence product quality so the two goodness of fit can produce distortion inaccuracy.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned defective, and the special fixture of a kind of automobile glass encapsulation bar welding is provided.
The scheme of the utility model is: comprise vertical clamping, laterally clamping; It is characterized in that: also set up a upper mold core bar, lower mold core bar in each clamping respectively; Cavity cross section inwall is identical on upper mold core bar cross section gabarit shape and type bent limit " H " the font edge cover strip; Upper mold core bar one port is 45 degree angles of chamfer, and cavity cross section inwall is identical under lower mold core bar cross section gabarit shape and type bent limit " H " the font edge cover strip, and lower mold core bar one port is 45 to spend angles of chamfer; During melting welding, upper mold core bar, lower mold core bar are linked in respectively in the cavity up and down of edge cover strip, and the core rod bar port of cutting sth. askew aligns with the edge cover strip angular cut.
The advantage of the utility model is: during melting welding, core rod bar rigid support edge cover strip makes it to dock that the goodness of fit is good, precision is high, indeformable.

Fig. 1 is existing clamp structure sketch map.
Fig. 2 is the A-A amplification view of Fig. 1.
Fig. 3 is the utility model structural representation.
The specific embodiment:
The utility model comprises vertical clamping 1, laterally clamping 2; It is characterized in that: also set up a upper mold core bar 4, lower mold core bar 5 in each clamping respectively; Cavity cross section inwall is identical on upper mold core bar 4 cross section gabarit shapes and type bent limit " H " the font edge cover strip 3; Upper mold core bar 4 one ports are 45 degree angles of chamfer, and lower mold core bar 5 cross section gabarit shapes are identical with type 3 times cavity cross sections of font edge cover strip, bent limit " H " inwall, and lower mold core bar 5 one ports are 45 degree angles of chamfer; During melting welding, upper mold core bar 4, lower mold core bar 5 are linked in respectively in the cavity up and down of edge cover strip 3, and the core rod bar port of cutting sth. askew aligns with edge cover strip 3 angular cuts.
During melting welding; Elder generation is inserted in edge cover strip 3 with the core rod bar and angular cut is alignd; Then put into die cavity, single mode matched moulds, two film slippage applying, yielding, melting welding, bimodulus secondary slippage applying, cooling, die sinking, get edge cover strip 3, the delivery core; Accomplish melting welding, the design of core rod bar realizes edge cover strip 3 rigidity butt welding.
