Abstract
The invention discloses a novel front-placed co-extrusion ring which comprises a co-extrusion ring body, wherein a pipe discharging through hole is formed in the co-extrusion ring body; a main runner is formed in the end surface of the feeding end of the co-extrusion ring body; branch runners are connected at the two ends of the main runner; sprues are formed in the two ends of each branch runner; the sprues are communicated with the pipe discharging through hole; a paint feeding channel is formed in the outer surface of the co-extrusion ring body inwards, and is communicated with the main runner; at least two bolt mounting holes are formed in the co-extrusion ring body; and the bolt mounting holes penetrate through the two ends of the co-extrusion ring body. Through the adoption of the structure, the front-placed co-extrusion ring is positioned at the headmost end of a pipe mouth mold of a pipe forming extruder, and when the pipe painting color needs to be changed, the length of waste pipes is approximately equal to the length of the xo-extrusion ring, so that the length of the generated waste pipes is greatly shortened, the rejection rate is effectively decreased, and the production cost is reduced.
Description
Technical field
The invention belongs to tubular object extruding field, be specifically related to a kind of novel preposition co-extrusion ring.
Background technology
Plastic pipe, because having the advantages such as current loss little, energy-conservation, material-saving, protecting ecology, completion is convenient, is widely used in the fields such as building water supply and drainage, cities and towns plumbing and Gas Pipe, becoming the main force of new century urban construction pipe network.Co-extrusion ring is arranged on the middle part of mould by existing novel preposition co-extrusion ring, when needing the color changing the co-extrusion bar spread upon on tubing, can produce and approximate mould adds the remaining Paint Daubs of co-extrusion ring one large section of useless tubing in the length of the forward part of co-extrusion ring, create great waste, overcome the above problems and become the task of top priority.
Summary of the invention
For solving above technical problem, the invention provides a kind of by preposition for co-extrusion ring, effectively can reduce the novel preposition co-extrusion ring of percent defective.
For achieving the above object, technical solution of the present invention is as follows:
A kind of novel preposition co-extrusion ring, comprise co-extrusion ring body (1), this co-extrusion ring body (1) is provided with tubing and goes out material through hole (2), its main points are: be provided with sprue (5) at the feed end end face of described co-extrusion ring body (1), the two ends of this sprue (5) are connected to branch flow passage (4), the two ends of this branch flow passage (4) are respectively equipped with cast gate (3), this cast gate (3) and described tubing go out material through hole (2) and are communicated with, the outer surface of described co-extrusion ring body (1) is inwardly provided with coating material feeding passage (6), this coating material feeding passage (6) is communicated with described sprue (5), described co-extrusion ring body (1) is provided with at least two bolt mounting holes (8), this bolt mounting holes (8) passes the two ends of described co-extrusion ring body (1) respectively.
Adopt above structure, the present invention is positioned at the tubing mouth mould of tube forming extruder foremost, when color smeared by needs replacing tubing, the length of useless tubing only approximates co-extrusion ring length, greatly reduce the length of the useless tubing of generation, effectively reduce percent defective, reduce production cost.
As preferably: described branch flow passage (4) is just to setting.Adopt above structure, rationally distributed.
As preferably: described cast gate (3) goes out material through hole (2) hoop around described tubing and is uniformly distributed.Adopt above structure, the co-extrusion bar smeared at pipe outer surface is evenly distributed, elegant in appearance.
As preferably: the feed end edge of described co-extrusion ring body (1) is provided with at least one and installs notch (9).Feed end edge be provided with at least one install notch (9).Adopt above structure, be convenient to installation and removal.
Beneficial effect: the novel preposition co-extrusion ring adopting above technical scheme, novel structure, is easy to realize, and greatly reduces the length of the useless tubing produced when changing co-extrusion bar and smearing color, effectively reduces percent defective, reduce production cost.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
As Figure 1-4, a kind of novel preposition co-extrusion ring, comprise co-extrusion ring body 1, this co-extrusion ring body 1 is provided with tubing and goes out material through hole 2, sprue 5 is provided with at the feed end end face of described co-extrusion ring body 1, the two ends of this sprue 5 are connected to branch flow passage 4, described branch flow passage 4 is just to setting, the two ends of this branch flow passage 4 are respectively equipped with cast gate 3, described cast gate 3 goes out material through hole 2 hoop around described tubing and is uniformly distributed, this cast gate 3 and described tubing go out material through hole 2 and are communicated with, the outer surface of described co-extrusion ring body 1 is inwardly provided with coating material feeding passage 6, this coating material feeding passage 6 is communicated with described sprue 5, described co-extrusion ring body 1 is provided with four bolt mounting holes 8, this bolt mounting holes 8 passes the two ends of described co-extrusion ring body 1 respectively.
As shown in Figure 1, Figure 3 and Figure 4, the feed end edge of described co-extrusion ring body 1 is provided with two and installs notch 9.
During use, form the feed end of tubing from the discharge end feeding co-extrusion ring body 1 of tubing mouth mould through cooling and shaping, carry out smearing of co-extrusion bar simultaneously, complete the tubing smeared and pass from the discharge end of co-extrusion ring body 1.
Finally need explanation; foregoing description is only the preferred embodiments of the present invention, those skilled in the art under enlightenment of the present invention, under the prerequisite without prejudice to present inventive concept and claim; can make like multiple types and representing, such conversion all falls within protection scope of the present invention.
