Multiply material in discharging channel 503 is not susceptible to mixing, ensure that the surface quality of the product of extrusion.
As shown in Figure 8, the close-up schematic view E of attached drawing 6 is shown as, can more be put down for the ease of multiply material
Slide, smoothly enter in the second extrusion manifold 503, the outside wall surface of shunting core 30 is with multiple along radially extending for shunting core 30
Second protrusion 3031, multiple second protrusions 3031 together constitute the second buffer part 303 of shunting core 30 and shunting core 30
The surface roughness of outside wall surface is 0.4~0.6, preferably 0.4.
As shown in Figure 9, it is in place around axial line expanded schematic diagram, the outside wall surface of shunting core 30 to be shown as part shunting core 30
Axially extended and the second dovetail-shape groove in being offered in each second charging material path 40, and the lower part tool of the second groove
There is an angle in 90 °~120 °, preferably 120 °；The lower part of second groove and the second buffer part 303 are adjacent, and shunting core 30
Outside wall surface on positioned at adjacent two strand second charging material path 40 between be provided with the second separating part 304, each second separating part 304
Thickness be 10~15 ㎜, preferably 15 ㎜.This is because the second charging material path of traditional continous way parison die is too short, from the
The material that two feed inlets 101 are squeezed into not yet is in time for expansion and is put into the second extrusion manifold 503, and multiply material easily occurs mixed
Melt and uneven, the shunting core 30 of the present embodiment can enable material to put down using the second charging material path 40 of this structure
Delay, uniformly enter in the second extrusion manifold 503, and multiply material second charging material path 40 in it is mutually isolated, material into
It can uniformly be unfolded after entering the second extrusion manifold 503, be spaced clearly between each material, it may therefore be assured that the plastics system of extrusion
The surface quality of product.
As shown in Figure 10, the F-F cut-away illustrations of attached drawing 9 are shown as, shunting core 30 has perforative second centre bore
301, the second aligning bar 60 is located in the second centre bore 301, and the second aligning bar 60 and 30 clearance fit of shunting core.The present embodiment
In continous way parison die 200 have compared with the prior art can manufacture color and quality is more various, surface quality more
The advantages of high plastic products.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that spirit is made, should be covered by the protection scope of the present invention.
