Abstract
The utility model provides a cooling device for the extrusion molding a pipe. The cooling device is arranged on pipe extrusion molding equipment, and the whole shape thereof is in a ring shape, wherein a hollow channel is arranged inside the ring; water inlet pipes are connected outside the ring for cooling water to be poured into the hollow channel; and the ring is also provided with a plurality of minor-caliber water outlet holes for the cooling water to spray from the hollow channel. By adopting the utility model, the water ring is arranged on the front segment of a vacuum tank, high-pressure water sprays out even water columns upwards, downwards, leftwards and rightwards around a sizing sleeve by the intensive small holes in the water ring, and thereby, a high-effective cooling area is formed between the sizing sleeve and the water ring, and the requirements that pipes are cooled and molded quickly at the moment of entering the sizing sleeve is realized, thus ensuring that the pipes have smooth surface and high molding accuracy.
Description
Technical field
The utility model belongs to the extruder fittings equipment of tubing production equipment, particularly relates to a kind of cooling device of tubing extrusion molding.
Background technology
At present in the plastic pipe extruding production line, just from the mould plasticizing forming, diameter is
Following tubule, temperature is very high; After entering vacuum sizing cover,, under the effect of the strong pulling force of high-speed tractor, make tube surfaces produce burr, not attractive in appearance easily if cooling effect is bad, even distortion.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, the cheap and cooling device of the significant tubing extrusion molding of cooling effect.
To achieve these goals, the technical scheme of employing is as follows:
A kind of cooling device of tubing extrusion molding, described cooling device is installed on the extrusion molding production equipment of tubing, its integral body in the form of a ring, the inside of ring is hollow channel, encircle external water inlet pipe, inject cooling water by water inlet pipe toward hollow channel, described ring also is provided with a plurality of small-bore apopores, and cooling water is outwards sprayed from hollow channel.
The inboard of described ring is provided with intensive small-bore apopore.
Described ring each side be connected with water inlet pipe.
Described ring adopts annulus, and the internal diameter of annulus is greater than the external diameter of calibration sleeve on the tubing extrusion molding production line, and described annulus is enclosed within the outer surface of calibration sleeve.
Further, the utility model adopts two or more annulus side by side, can determine according to the length of calibration sleeve.
The utility model also is provided with the annulus flange, described annulus flange is arranged on a side of annulus, it is arranged with two water inlet pipe installing ports, the circumference of annulus flange also is provided with the installation screw hole that is installed in the vacuum tank inside on the tubing extrusion molding production line, and also is provided with the calibration sleeve screw hole that is connected with calibration sleeve.
Adopt the utility model, after vacuum tank was loaded onto water ring, because the leading portion of vacuum tank is loaded onto water ring, water under high pressure was by the intensive aperture in water ring the inside, about spraying, about to well-proportioned water column around calibration sleeve; This moment, calibration sleeve and water ring have formed an efficient cooling zone, and when having realized that tubing has just entered calibration sleeve, the rapid technological requirement of cooling forming makes smooth surface, the formed precision height of tubing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structural representation of the present utility model as shown in Figure 1, wherein left-half is a cutaway view, right half part is a side view, it comprises water ring 1, water ring flange 2, water ring left and right sides water inlet 3, calibration sleeve fixed screw holes 4, water ring fixed screw holes 5.
Operation principle of the present utility model is as follows:
Vacuum sizing is applied mechanically on the screw hole 4 that screw is fixed on water ring flange 2, make water ring 1 on the peripheral equipment of calibration sleeve as the high-pressure spraying device, by water ring fixed screw holes 5 water ring flange 2 is fixed on the vacuum tank leading portion with screw, after water ring 1 left and right sides water inlet 3 connects water under high pressure, water under high pressure gushes out from the thickly dotted aperture in water ring 1 the inside, water column from about, up and down, be sprayed onto on the calibration sleeve equably, this moment, formed an efficient cooling zone in the interval of calibration sleeve and water ring 1, just from the mould plasticizing forming, diameter is
Following tubule, temperature is very high, enter behind the calibration sleeve cooling forming rapidly, tube surfaces through water ring 1 cooling is smooth, the formed precision height, it is bad because of cooling effect to have solved prior art, causes under the effect of the strong pulling force of high-speed tractor, cause tube surfaces burr, not attractive in appearance, even the defective of distortion.
