Abstract
The utility model is achieved in that composite co-extruding die head, be made up of upper die body, lower mold body, upper die lip, lower die lip, it is characterized in that: upper die body, lower mold body, on die lip, lower die lip is provided with oily circulation port, upper die lip is made up of front die lip and rear die lip, upper and lower die lip is fixed on upper and lower die body by trip bolt, between front die lip and rear die lip, be provided with gathering sill, the gap between gathering sill and upper and lower die lip is through.Gathering sill between front die lip and rear die lip is arc line type shape, and the melt flow channel between upper and lower die body has angle.The angle that gathering sill and runner are formed is acute angle.The base material entering gathering sill is steel band, netted glass etc.The utility model has the advantages that the upper die lip split-type structural design of employing, have gathering sill in the middle of die lip, this gathering sill is arc line type shape, and is acute angle with the angle that runner is formed, be convenient to outside base material and enter runner and melt compound by gathering sill, coextrusion die orifice together.
Description
Technical field
The utility model relates to a kind of composite co-extruding die head, refers to the outside base material of importing and the co-extrusion die head of melt compound especially.
Background technology
Now used in injection moulding industry extrusion die is all upper and lower die body, up and down die lip.When outside base material needs to enter runner and melt compound through die body, together during coextrusion die orifice, the die head of current routine just cannot realize, urgently existing extrusion die is improved, runner and melt compound is entered to have guaranteed outside base material, coextrusion die orifice together, forms composite.
Summary of the invention
The utility model, in order to overcome the problems referred to above, provides a kind of composite co-extruding die head, is convenient to outside base material and enters runner and melt compound, coextrusion die orifice together through die body.To achieve these goals, the utility model is achieved in that composite co-extruding die head, be made up of upper die body, lower mold body, upper die lip, lower die lip, it is characterized in that: upper die body, lower mold body, on die lip, lower die lip is provided with oily circulation port, upper die lip is made up of front die lip and rear die lip, upper and lower die lip is fixed on upper and lower die body by trip bolt, between front die lip and rear die lip, be provided with gathering sill, and the gap between gathering sill and upper and lower die lip is through.Gathering sill between front die lip and rear die lip is arc line type shape, and the melt flow channel between upper and lower die body has angle.The angle that gathering sill and runner are formed is acute angle.The base material entering gathering sill is steel band, netted glass etc.
The utility model has the advantages that the upper die lip split-type structural design of employing, have gathering sill in the middle of die lip, this gathering sill is arc line type shape, and is acute angle with the angle that runner is formed, be convenient to outside base material and enter runner and melt compound by gathering sill, coextrusion die orifice together.

Detailed description of the invention
Composite co-extruding die head, be made up of upper die body, lower mold body, upper die lip, lower die lip, upper die body, lower mold body, on die lip, lower die lip is provided with oily circulation port, upper die lip is made up of front die lip and rear die lip, upper and lower die lip is fixed on upper and lower die body by trip bolt, between front die lip and rear die lip, be provided with gathering sill, the gap between gathering sill and upper and lower die lip is through.Gathering sill between front die lip and rear die lip is arc line type shape, and the melt flow channel between upper and lower die body has angle.The angle that gathering sill and runner are formed is acute angle.The base material entering gathering sill is steel band, netted glass etc.
As Fig. 2 can shown in Fig. 3, die head forms by by upper die body 1, lower mold body 5, upper die lip 2, lower die lip 6.Die body 1,5, die lip 2,6 is provided with oily circulation port 7, and upper and lower die lip 2,6 is fixed on upper and lower die body 1,5 by trip bolt.Upper die lip 2 is made up of front die lip 21 and rear die lip 22.Form gathering sill 4 between front die lip 21 and rear die lip 22 mating surface, this gathering sill is arc line type shape, and is acute angle with the angle that melt flow channel is formed, and outside base material 3 enters runner and melt compound by gathering sill 4, coextrusion die orifice together.
When needing the goods preparing variable thickness, changing lower die lip 6 and can change die orifice size, both having obtained the goods of different-thickness.
Claims (4)
