The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the specific embodiment of the present utility model is described in further detail, and to help those skilled in the art, inventive concept of the present utility model, technical scheme is had more complete, accurate and deep understanding.
Structure of the present utility model as expressed in Fig. 1 to Fig. 3 is co-extruding mould after a kind of extrusion molding four chamber press strips, comprises current divider 1, two shunt conduit, the little die head of co-extrusion, wet type shaper and water tanks.
Each shunt conduit comprises connector 4 under co-extrusion mouth upper connector 2, co-extrusion mouth, and co-extrusion mouth upper connector 2 is fixedly connected with current divider 1; Under the co-extrusion mouth, connector 4 is fixedly connected with co-extrusion die head.Under co-extrusion mouth upper connector 2, co-extrusion mouth, connector 4 connects fastening by attaching nut 3.
The little die head of co-extrusion is provided with die head template 5, mouthful mould 7, mouthful mould 8, die head cover plate 9; Also comprise section bar product 10.
As shown in Figure 2, die head template 5 is fastenedly connected with fixture 13.
In order to solve the problem that prior art exists and to overcome its defective, realize satisfying the requirement of profile shapes high speed extrusion production capacity, the goal of the invention that reduces production costs, the technical scheme that the utility model is taked is:
As shown in Figure 1 to Figure 3, after extrusion molding press strip provided by the utility model, co-extruding mould is provided with four press strip forming cavity, and each described shunt conduit is divided into two passages again in described co-extrusion die head, passes into respectively two press strip forming cavity.
The utility model adopts technique scheme, satisfied the requirement of profile shapes high speed extrusion production capacity, reduced production costs, greatly degree facilitates the producer's operation, improved the Multicarity utilization rate of co-extrusion section bar mould after the adhesive tape, for promoting the use of of co-extruding mould after adhesive tape lays the first stone.
Described co-extrusion die head is robbed connector 12 with baking and is fixedly connected with.Baking is robbed connector 12 and is robbed 11 with baking and be connected.
