Abstract
The utility model provides an extruding formation head for plastic products, comprising a core rod, a delamination extruding sleeve and an outer sleeve which are sheathed at the periphery of the core rod, a formation mold core which is fixed on the top of the core rod and a formation sleeve which is arranged at the periphery of the formation mold core and fixedly connected with the outer sleeve. The core rod and the outer surface of the delamination extruding sleeve are provided with a spiral flow passage. The extruding formation head for plastic products is characterized in that the core rod and the outer column surface of the delamination extruding sleeve are respectively provided with incremental distribution flow passages along the circumference evenly, and the distribution flow passages are communicated with spiral flow passages which are arranged on the surfaces of the delamination extruding sleeve and a delamination extruding feed inlet. The delamination extruding feed inlet is arranged on the outer sleeve of the head in a radial direction. Under the same extruding layer, the diameter of the extruding head of the utility model is smaller than the extruding head in the prior art, and the manufacturing equipment and the production efficiency are better than the prior art. The extruding formation head for plastic products is specially suitable for the extruding of the multi-layer composite plastic.
Description
Technical field
The utility model relates to a kind of plastic extruding forming head, belongs to the plastic extruder tooling device
Technical field.
Background technology
In plastic sheeting multi-layer forming extruding technology field, for different materials is extruded simultaneously, need a plurality of charging apertures and multilayer extrusion channel be set at head, and will make charging even, also need with the raw material of charging aperture again uniform distribution on the head circumference, the Canadian Bin Dun of the many employings of the head of plastic extruding forming at present company technology, its sub-material runner is a radial arrangement, head is provided with material separating disc, extruding layer is many more, the material separating disc diameter is big more, complex structure, and volume is bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of plastic extruding forming head, makes the sub-material runner extrude the axial arranged of cover in layering, material separating disc need be set, with simplified structure, and reduced volume.
The technical solution of the utility model is achieved in that this plastic extruding forming head, basic structure comprises: plug, cover is extruded in the layering that is sleeved on the plug periphery, overcoat, be fixed on the formation die core at plug top, be arranged on formation die core peripheral with overcoat affixed become jacket, the outer surface that cover is extruded in plug and layering is provided with helical flow path, it is characterized in that: plug and layering are extruded the cover outer cylinder and along circumference the sub-material runner that increases progressively evenly are set respectively, and the sub-material runner is communicated in that charging aperture is extruded in layering that the head overcoat radially is provided with and the helical flow path that the cover surface is provided with is extruded in layering.
The sub-material runner of described plastic extruding forming head increases with arithmetic series along the cylinder generatrix direction from charging aperture.
The layering of described plastic extruding forming head is extruded cover and can be set to one or more.
The layering of described plastic extruding forming head is extruded charging aperture and is arranged on the same cross section.
The sub-material runner section that the cover outer surface is extruded in the plug of described plastic extruding forming head and layering is a column structure, and the helical flow path section is a tapered structure.
Plastic extruding forming head provided by the utility model is set directly at plug with the sub-material runner and the cover outer surface is extruded in layering, has saved material separating disc, and the volume of head is reduced, and processing technology is simple, is particularly useful for the processing of multilayer extrusion plastic.

The specific embodiment
Fig. 1, be structure master's cutaway view of the present utility model, basic structure comprises: plug 4, the multilayer that connects together extruded cover 10, overcoat 9, moulding core 2, become jacket 1; Plug 4 and multilayer are extruded cover 10 outer surface tops helical flow path 7,8 are set, extrude cover outer cylinder bottom in plug and multilayer and sub-material runner 3 evenly is set along circumference, the sub-material runner from charging aperture along the cylinder generatrix direction with 1,2,4 ... ratio increase step by step, sub-material runner 3 is communicated with charging aperture 5,6 and helical flow paths 7,8; The sub-material road section that the outer surface of cover 10 is extruded in plug 4 and layering is a column structure, and the helical flow path section is a tapered structure; Layering is extruded cover 10 and can be set to one or more; A plurality of layerings are extruded charging aperture and can be arranged on the same cross section.
Fig. 2, Fig. 3, Fig. 4 have provided the radial distribution schematic diagram that charging aperture is extruded in sub-material runner that layering step by step extrudes and layering respectively.
Fig. 5, Fig. 6 have provided the schematic diagram that prior art layering extruder head material separating disc 16 is provided with.
By more as can be seen, under the identical situation of extruding layer, extruder head diameter of the present utility model is much smaller than the prior art extruder head, and manufacturing equipment and production efficiency are all because prior art especially is fit to extruding of multilayer composite plastic.
