Abstract
The utility model discloses an extruded sheet broad width extrusion tooling, including Y section mould chamber, die lip, L groove, Y section mould chamber straightway is the feed zone, the opening section is the runner chamber, and the export of runner chamber sets gradually L groove and die lip, and the flow length in runner chamber is 7~8mm. The utility model discloses an improve the inside runner chamber type of die cavity, be 7~8mm with flow length for flow the chamber and possess the adjustability, adopt 600mm broad width mould can produce 900~1300mm panel.
Description
Technical field
This utility model is related to extruded sheet process units technical field and in particular to extruded sheet wide cut extrusion die.
Background technology
Extruded polystyrene foam board, also known as xps extruded sheet, is the material through there being special process continuous extrusion foaming molding
Material, the dura mater uniform ground that its surface is formed, internal closed-cell foam continuous uniform completely, become alveolate texture, therefore there is height
Resistance to compression, lightweight, do not absorb water, airtight wear-resisting, non-degradable characteristic, be one of inexpensive construction material of current building industry.
Extruded sheet follows legacy equipment for these years always and produces, and its operation principle is as follows: by feeding workman the raw material of certain formula
After mixing in blender, it is added in production equipment；Production equipment adds the double rank machine of single screw rod composition for single screw rod, is injected simultaneously into
Foaming agent, is gone out by mould through the double rank machine extruded plastic foam of single screw rod, then after screed and traction come adjustment length and width,
Cooled down by cooling frame, by saw blade ripsaw side, the crosscutting cut-out of saw blade, finally carry out length with heating wire again and accurately cut then to become
For finished product, packaging listing.In the extrusion of mould, the structure of extrusion die cavity, size are most important, existing extrusion die cavity
Size is non-adjustable, is only capable of producing a kind of product, adaptability is weaker, and production capacity is low, and production cost is high.
Content of the invention
Goal of the invention: for the deficiencies in the prior art, this utility model provides a kind of extruded sheet wide cut extrusion die, has
Controllability, can produce the extruded sheet of different size.
Technical scheme: extruded sheet wide cut extrusion die described in the utility model, including y pattern chamber, die lip, l groove；Y type
Die cavity straightway is feed zone, open section is flow passage chamber, and flow passage chamber outlet sets gradually l groove and die lip, the long flow path of flow passage chamber
Spend for 7 ~ 8mm.
Improve technique scheme further, the operation length of described flow passage chamber is 7.5mm.
Further, the flow passage chamber in described y pattern chamber is divided into outer tract and interior tract, and outer tract is with feed zone arc even
Connect, the pointed shape that the corresponding feed zone of interior tract is formed.
Beneficial effect: compared with prior art, advantage of the present utility model: this utility model passes through to improve mold cavity stream
Road lumen type, operation length is 7 ~ 8mm so that stream chamber possesses adjustability, can produce 900 ~ 1300mm using 600mm wide cut mould
Sheet material.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below by accompanying drawing, technical solutions of the utility model are described in detail.
Embodiment 1: extruded sheet wide cut extrusion die as shown in Figure 1, including y pattern chamber, die lip 1, l groove 2；Y pattern chamber
Straightway is feed zone 4, open section is flow passage chamber 3, and flow passage chamber 3 outlet sets gradually l groove 2 and die lip 1, the flow process of flow passage chamber 3
Length is 7.5mm.The flow passage chamber 3 in y pattern chamber is divided into outer tract and interior tract, and outer tract is connected with feed zone arc, interior tract
The pointed shape that corresponding feed zone is formed.
The operation length of flow passage chamber 3 is 7.5mm, with respect to conventional 10mm, y pattern chamber can be moved simultaneously in mould
Thus possess controllability, the sheet material of different size can be produced.
Although as described above, having represented with reference to specific preferred embodiment and having described this utility model, it must not
It is construed to the restriction to this utility model itself.In the spirit and scope of the present utility model defining without departing from claims
Under the premise of, can various changes can be made in the form and details to it.
Claims (3)
1. extruded sheet wide cut extrusion die it is characterised in that: include y pattern chamber, die lip, l groove；Y pattern chamber straightway is charging
