Description

Inwall forms the extrusion molding device of the drainage pipe of spirality projection

The utility model relates to a kind of extrusion molding device of making drainage pipe, and particularly a kind of inwall forms the extrusion molding device of the drainage pipe of spirality projection.

The drainage pipe that now uses generally is to be raw material with resin or engineering plastics, makes pipe shape goods by single lead screw ex truding briquetting machine, and its inwall all is smooth.This drainage pipe is bigger to the resistance of current, and drainage efficiency is lower, and pipe material inner wall and the serious noise of waste water friction meeting generation.

The purpose of this utility model is to provide a kind of inwall to form the extrusion molding device of the drainage pipe of spirality projection, make the pipe material inner wall of extrusion molding form spiral salient, thereby the waste water that can make inflow is at the inner whirlpool that forms of tubing, so that waste water is discharged rapidly, can abate the noise, improve drainage efficiency.

The technical solution of the utility model is:

A kind of inwall forms the extrusion molding device of the drainage pipe of spirality projection, comprise and extrude die body, die sleeve, core rod, one end of this die sleeve is fixedlyed connected with the extrusion die body, core rod is set in die sleeve and extrudes within the die body, between core rod and extrusion die body and die sleeve, form and extrude runner, this extrudes runner one end and forms outlet, and the other end is connected with the side charging aperture that is located at this extruding dies body sidewall, it is characterized in that:

Extrude die body and the sheathed swivel bearing axle in core rod center, be provided with the extrusion runner of perforation at this swivel bearing axle center, the fixedly connected sprocket wheel cover of this swivel bearing axle one end, sprocket wheel puts and sets firmly a sprocket wheel, and sprocket wheel is connected with motor and variable transmission mechanism; A mould end cap is established in the sprocket wheel outside, and this mould end cap center and sprocket wheel cover center are equipped with the extrusion runner that the extrusion runner with swivel bearing axle center connects, and are formed centrally central charging aperture in this mould end cap; The other end of this swivel bearing axle is expanding into the bell mouth shape core retainer plate near described outlet place, in this core retainer plate, fix sheathed one conical fixedly shuttle, should be fixedly shuttle week sidewall be provided with a plurality of grooves, this gap that fixedly formation is connected with described outlet between shuttle sidewall and this core retainer plate inwall.

Effect of the present utility model is: liquid material enters the extrusion runner simultaneously from side charging aperture and central charging aperture, from the continuous extrusion molding drainage pipe of outlet, because the core retainer plate of swivel bearing axle and the fixedly turning effort of shuttle, make the drainage pipe inwall of moulding form the spirality projection, after in being installed to drainage pipeline, the waste water formation whirlpool of inflow is discharged rapidly, thereby improve drainage efficiency, reduce noise.

Fig. 1 is the structure cutaway view of a kind of preferred embodiment of the utility model.

Fig. 2 is the A-A cutaway view among Fig. 1.

Fig. 3 is the three-dimensional exploded view of the swivel bearing shaft portion among Fig. 1.

The utility model will be described in further detail as follows in conjunction with the accompanying drawings:

With reference to Fig. 1.The utility model comprises extrusion die body 1, die sleeve 2, core rod 3, die sleeve 2 is fixed on an end that extrudes die body 1, core rod 3 is set in and extrudes in die body 1 and the die sleeve 2, at core rod 3 and extrusion die body 1 and 2 formation extrusion of die sleeve runner 11, this extrudes runner 11 1 ends and forms outlet 13, the other end is connected with the side charging aperture 12 that is located at this extrusion die body 1 sidewall, extruding die body 1 and the sheathed swivel bearing axle 5 in core rod 3 centers, swivel bearing axle 5 centers are provided with the extrusion runner 4 of perforation, in conjunction with reference to Fig. 2 and Fig. 3, the fixedly connected sprocket wheel cover 10 of these swivel bearing axle 5 one ends, fixedly establish a sprocket wheel 9 on the sprocket wheel cover 10, sprocket wheel 9 is connected with motor and variable transmission mechanism, sprocket wheel cover 10 is bearing on the bearing 15, a mould end cap 16 is established in sprocket wheel 9 outsides, and the center of the center of mould end cap 16 and sprocket wheel cover 9 is equipped with the extrusion runner that communicates with the extrusion runner 4 at swivel bearing axle 5 centers, and forms central charging aperture 12 ' in the port.Swivel bearing axle 5 is held in addition at the core retainer plate 6 that expands into bell mouth shape near outlet 13 places, mat two screws fixing sheathed one conical fixedly shuttle 7 in the core retainer plate 6, fixedly shuttle 7 all sidewalls are provided with a plurality of grooves 8, fixedly form the gap that is connected with outlet 13 between shuttle 7 sidewalls and core retainer plate 6 inwalls.Liquid raw material is pressed into by extruding runner 11 from side material mouth 12 and extrudes from outlet 13, make continuous extrusion molding tubing P, simultaneously, also be pressed into raw material from central charging aperture 12 ', by extruding runner 4 from the tubaeform core retainer plate 6 of swivel bearing axle 5 and the fixedly process of the crack between the shuttle 7 process outlet 13 extrusion, form the one projection at the inwall of tubing P,, form spirality projection 14 at tubing P inwall along with the rotation of sprocket wheel 9 driven rotary bolsters 5.

The degree of depth of the groove 8 of the fixedly shuttle 7 of adjustment swivel bearing axle 5 can form different spirality projectioies at pipe material inner wall.
