Abstract
The utility model relates to an american plastic profile's extrusion tooling, including the die body that sets gradually, mounting panel, cylinder manifold, bush no. 3, bush no. 2 and bush no. 1 to dispose the mandrel, the shaping has die cavity and an interior runner, the die body inner chamber is provided with feeding reposition of redundant personnel awl, bush no. 2 disposes the plug, the tip shaping of plug is bored for the reposition of redundant personnel, just reposition of redundant personnel awl stretch into to interior runner. This structure has realized that material flow and the pressure from interior two die cavities of runner inlet port mould in is adjustable to guaranteeing material fashioned density in the die cavity, helping obtaining better section bar quality, this design is particularly suitable for the complicated american plastic profile preparation of cross sectional shape, can improve the shaping quality of section bar.
Description
Technical field
The utility model relates to the extrusion molding field of profile shapes, is specifically related to a kind of extrusion die of American plastic irregular profile.
Background technology
Profile shapes is cross section is non-circular extruded product, is often referred to the plastic irregular profile of plastics for main material, is widely used in the industries such as construction and decoration.Plastic irregular profile is mainly obtained by extrusion molding, its general flow can sketch into by polymeric particles material in barrel through screw mixing, heating and melting is viscous state uniformly, material under the promotion of rotary screw to heading screw, enter the mould of head, die cavity at high temperature under high pressure through mould realizes shunting compression forming, extrude the parison of approximately prepd section, then vacuum cooled sizing is realized through shaper, reach Products Design requirement, and then through bosh, draw-gear, namely final molding product is obtained after the follow-up equipment processing such as cutting machine.In whole profile shapes process, the mode of heating of material, the control of the sizing of the mass transfer mode of material between head and barrel, parison and the type of cooling, hauling speed and each workshop section job parameter all can have an impact to the final mass of profile shapes goods, and the qualification rate extrusion molding apparatus of existing profile shapes being continued to optimize to improve to product is the problem that those skilled in the art constantly explore.
American profile shapes is compared other section bars and is had more complicated cross sectional shape, corresponding mold structure is also more complicated, time shaping, material enters the flow of die cavity by runner and pressure all can have a direct impact shaping quality, by controlling the flow of material in mould and pressure to adapt to the shaping needs of section bar, and then the section bar obtaining more high-quality is the problem that those skilled in the art constantly explore.
Utility model content
Technical problem to be solved in the utility model is the extrusion die providing a kind of profile shapes for above-mentioned prior art, be particularly suitable for the shaping of American profile shapes, the adjustment of mass flow and pressure in inner flow passage and die cavity can be realized, be beneficial to obtain more shaping quality.
The technical scheme in the invention for solving the above technical problem is: a kind of extrusion die of American plastic irregular profile, comprise the die body, supporting plate, cylinder manifold, mouth mould three, mouth mould two and the mouth mould one that set gradually, and be configured with core, form die cavity and inner flow passage, described die body inner chamber is provided with charging spreader, it is characterized in that: described mouth mould two is configured with plug, and the end of described plug is shaped to spreader, and described spreader stretches to described inner flow passage.
In the utility model, it is fastening that above-mentioned each building block realizes connection by screw.
Compared with prior art, the utility model has the advantage of: by the plug end at mouth mould two, spreader is set, the adjustment entering mass flow in die cavity and pressure from inner flow passage can be realized, thus ensure the density that material is shaping in die cavity, contribute to obtaining better section bar quality, this design is particularly suitable for the American plastic irregular profile preparation of cross sectional shape complexity, can improve the Forming Quality of section bar.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figures 1 to 6, the extrusion die of the American plastic irregular profile in the present embodiment, comprise die body 1 and be successively set on the supporting plate 2 of die body rear end, cylinder manifold 3, mouth mould 34, mouth mould 25 and mouth mould 1, aforementioned each building block is connected by trip bolt 7, core 9 is configured with in mould, form die cavity A and inner flow passage B, die body inner chamber is provided with charging spreader 8, mouth mould 25 is configured with plug 10, the end of described plug 10 is shaped to spreader 11, and spreader 11 stretches to described inner flow passage B.
The extrusion die of said structure, achieve material in the adjustment entering corresponding cavity pressure and flow from inner flow passage B, thus ensure the density that material is shaping in die cavity, contribute to obtaining better section bar quality, this design is particularly suitable for the American plastic irregular profile preparation of cross sectional shape complexity, can improve the Forming Quality of section bar.
