Description
Technical field
The utility model relates to the technical field of extrusion die, particularly, relate to a kind of plastic pipe adjust separately layer multi-layer co-extruded mould.
Background technology
At present, when domestic multi-layer tubes mould co-extrusion, is to be generally all directly coated on pipe outer surface by the runner of extrusion die, co-extruding flow channel is fixed in extrusion die, when the tubing of production high-quality in this way, need to be very high to the requirement on machining accuracy of mould; In the time occurring that co-extrusion is in uneven thickness, substantially cannot regulate the ratio between each layer, thereby cause the decline of pipe workpiece quality.
Utility model content
In order to overcome the deficiencies in the prior art, it is a kind of simple in structure, easy to adjust that the utility model provides, can realize the uniform plastic pipe of pipe co-extrusion layer adjust separately layer co-extruding mould.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of plastic pipe is adjusted separately the multi-layer co-extruded mould of layer, comprise a mouthful mould, plug, tapered shunting device, die body front-end block, die body intermediate mass and die body back-end block, described die body front-end block, die body intermediate mass is connected successively with die body back-end block, described die body intermediate mass is provided with outer extrusion, described die body back-end block is provided with intermediate layer extrusion, between described die body front-end block and die body intermediate mass, be embedded with outer regulating block separately, between described die body intermediate mass and die body back-end block, be embedded with the independent regulating block in intermediate layer, described outer extrusion is communicated with outer regulating block separately, described intermediate layer extrusion is communicated with the independent regulating block in intermediate layer.
Between the independent regulating block of described skin and die body, it is matched in clearance.
Between the independent regulating block in described intermediate layer and die body, it is matched in clearance.
The independent regulating block of the independent regulating block of skin of the present utility model and intermediate layer narrow gap respectively and together with existing between die body, described gap is for controlling the uniformity of tubing coextruded layer.
The independent regulating block of described skin is the sliding shoe with inclined-plane.
The independent regulating block of skin in the utility model is the sliding shoe with inclined-plane, the effect on inclined-plane can contribute to the circulation of stream material, also contribute to the space of inclined-plane and die body intermediate mass to regulate, when sliding shoe rises, the change of gap, inclined-plane is large, and outer laminar flow material can increase, and outer layer thickness increases, on the contrary, when the sliding shoe inclined-plane gap smaller that declines, outer laminar flow material can reduce, outer layer thickness attenuation.
The independent regulating block in described middle level is the sliding shoe with inclined-plane.
The independent regulating block in middle level in the utility model is the sliding shoe with inclined-plane, the effect on inclined-plane can contribute to the circulation of stream material, also contribute to the space between inclined-plane and die body back-end block to regulate, when sliding shoe rises, the change of gap, inclined-plane is large, and middle laminar flow material can increase, and intima-media thickness increases, on the contrary, when the sliding shoe inclined-plane gap smaller that declines, middle laminar flow material can reduce, intima-media thickness attenuation.
The independent regulating block of the independent regulating block of described skin and intermediate layer is adjusted the gap between itself and die body by screw.
Compared with prior art, the beneficial effect the utlity model has: plastic pipe of the present utility model is adjusted separately the co-extruding mould of layer, utilize the slip of independent regulating block, control the gap between slide block and extrusion die, realize and regulate tubing position in uneven thickness, avoided like this high request to Mould Machining precision, cannot regulate the problem of the uniformity ratio between each layer simultaneously, reduce the manufacturing cost of mould, improved the product quality of multi-layer tubes.
Accompanying drawing explanation
Fig. 1: a kind of plastic pipe is adjusted separately the multi-layer co-extruded mould structure schematic diagram of layer.
In figure: 1. mouthful mould; 2. plug; 3. current divider; 4. die body front-end block; 5. die body intermediate mass; 6. die body back-end block; 7. outer extrusion; 8. intermediate layer extrusion; 9. outer regulating block separately; 10. the independent regulating block in intermediate layer; 11. screws.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As Fig. 1, a kind of plastic pipe is adjusted separately the multi-layer co-extruded mould of layer, comprise mouthful mould 1, plug 2, tapered shunting device 3, die body front-end block 4, die body intermediate mass 5 and die body back-end block 6, described die body front-end block 4, die body intermediate mass 5 is connected successively with die body back-end block 6, described die body intermediate mass 5 is provided with outer extrusion 7, described die body back-end block 6 is provided with intermediate layer extrusion 8, between described die body front-end block 4 and die body intermediate mass 5, be embedded with outer regulating block 9 separately, described skin regulates separately 9 for the sliding shoe with inclined-plane, narrow gap together with having between the independent regulating block 9 of described skin and die body intermediate mass 5, between described die body intermediate mass 5 and die body back-end block 6, be embedded with the independent regulating block 10 in intermediate layer, the independent regulating block 10 in described middle level is the sliding shoe with inclined-plane, narrow gap together with having between the independent regulating block 10 in described intermediate layer and die body back-end block 6, described outer extrusion 7 is communicated with outer regulating block 9 separately, described intermediate layer extrusion 8 is communicated with the independent regulating block 10 in intermediate layer, the independent regulating block 10 of the independent regulating block 9 of described skin and intermediate layer is adjusted the gap between itself and die body by screw 11.
Operation principle of the present utility model: when plastics enter the independent regulating block 10 in intermediate layer, extruding pipe material intermediate layer from intermediate layer extrusion 8; Plastics enter outer regulating block 9 separately, extruding pipe material skin from outer extrusion 7.In the time of outer tube and intermediate layer pipe in uneven thickness, judge tubing position in uneven thickness with visual method, by regulating the screw 11 of independent regulating block of the external correspondence of the corresponding extrusion die in this position, outer regulating block 9 separately and the independent regulating block 10 in intermediate layer slide, the gap that makes regulating block and extrude between die body becomes large or dwindles, thereby control stream material size, until the thickness adjustment of tubing reaches even.
