Abstract
The invention discloses a pipe extruding machine outlet mold. The pipe extruding machine outlet mold comprises a pipe mouth mold and a co-extrusion ring. The discharge end of the pipe mouth mold is connected with the feed end of the co-extrusion ring. The co-extrusion ring is provided with a pipe discharge through hole. The feed end face of the co-extrusion ring is provided with a main runner. The two ends of the main runner are connected with branch runners respectively. The two ends of each branch runner are provided with sprues respectively. The sprues are communicated with the pipe discharge through hole. The outer surface of the co-extrusion ring is inwards provided with a painting feeding channel. The painting feeding channel is communicated with the main runner. According to adoption of the structure, the co-extrusion ring is located at the uttermost front end of the whole mold, so that when a pipe is needed to be replaced and painting is needed to be smeared, the length of a waste pipe is merely approximately equal to the length of the co-extrusion ring. Therefore, the length of the produced waste pipe is greatly reduced, the rejection rate is effectively lowered, and the production cost is reduced.
Description
Technical field
The invention belongs to tubular object extruding field, be specifically related to a kind of pipe extruder outlet die.
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 pipe extruder outlet die, 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 pipe extruder outlet die of percent defective.
For achieving the above object, technical solution of the present invention is as follows:
A kind of pipe extruder outlet die, comprise tubing mouth mould (A) and co-extrusion ring (B), the discharge end of this tubing mouth mould (A) is connected with the feed end of described co-extrusion ring (B), this co-extrusion ring (B) 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 (B), 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 (B) is inwardly provided with coating material feeding passage (6), this coating material feeding passage (6) is communicated with described sprue (5).
Adopt above structure, co-extrusion ring (B) is positioned at whole mould 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 (B) is provided with at least one and installs notch (9).Adopt above structure, be convenient to the installation of co-extrusion ring (B).
As preferably: be provided with at least two bolt mounting holes (8) on described co-extrusion ring (B), this bolt mounting holes (8) passes the two ends of described co-extrusion ring (B) respectively.Adopt above structure, make the connection of tubing mouth mould (A) and co-extrusion ring (B) more firm.
As preferably: described co-extrusion ring (B) is fixedly connected with described tubing mouth mould (A) by bolt, this bolt is threaded with described tubing mouth mould (A) afterwards through described bolt mounting holes (8).Adopt above structure, simple, reliable and be easy to realize.
As preferably: be provided with die cavity (1) in described tubing mouth mould (A), this die cavity (1) discharge end and tubing go out material through hole (2) and are communicated with, and the internal diameter of described die cavity (1) feed end increases from inside to outside gradually.Adopt above structure, that effectively improves the production efficiency of tubing and co-extrusion bar smears efficiency.
Beneficial effect: the pipe extruder outlet die 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 Fig. 1, shown in Fig. 3 and Fig. 4, a kind of pipe extruder outlet die, comprise tubing mouth mould A and co-extrusion ring B, the discharge end of this tubing mouth mould A is connected with the feed end of described co-extrusion ring B, this co-extrusion ring B 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 B, 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, this cast gate 3 and described tubing go out material through hole 2 and are communicated with, namely described cast gate 3 goes out material through hole 2 hoop around described tubing and is uniformly distributed, the outer surface of described co-extrusion ring B is inwardly provided with coating material feeding passage 6, this coating material feeding passage 6 is communicated with described sprue 5.
