The present invention is an apparatus for forming an anti-stretch corrugated tube for extrusion molding a corrugated tube having vertical and horizontal drainage pipes, which are installed to promote dehydration of soft ground containing a lot of water such as tidal or coastal or swampy areas. More particularly, the present invention relates to a drainage material. More specifically, in a corrugated oil pipe forming device consisting of an extrusion die, a cutter device, and a multi-split mold, the die is formed by a mold formed by a groove formed on a discharge port side of an extrusion die for supplying a synthetic resin melt. The stretching prevention layer for forming a thick resin layer in the longitudinal direction of the corrugated oil tube extruded into the multi-divided mold is continuously formed to be extruded to prevent shrinkage and expansion of the extruded corrugated hole tube as well as stretching. And prevents warping, and configured to be coupled to the rear of the extrusion die It can be blown 360 ° from the inside of the mold by the injection holder and at the same time prevents air leakage by air packing, and it is possible to blow molding at low pressure.One side mold and the other side are formed from the corrugated oil pipe formed by the anti-curling bar. The present invention relates to a molding apparatus and a drainage material that facilitates desorption during desorption of a mold mold matched with a mold, and prevents the corrugated oil pipe from sticking to the mold mold.

Conventionally, an extruded tube having the same thickness is molded by a molding apparatus having an endless track, and perforated inward or outward to produce a perforated tube.

However, as described above, the hole tube having the same thickness had a drawback that temporary contraction and expansion occur depending on the degree of tension during installation.

In addition, spiral or asymmetric spiral tube pipes made of PE are also susceptible to problems of shrinkage and expansion, ductility, deformation, and warpage, and are easily ruptured by anchor plates coupled during installation. There was a problem of work delay due to the complexity and difficulty in installation, such as quality control being degraded due to the limited space of the inner pore treatment.

The present invention is made of a thick mold in the longitudinal direction of the corrugated hollow tube is formed into the mold mold by the groove formed on the discharge port side of the extrusion die for supplying a synthetic resin melt to solve the conventional drawbacks. The stretch prevention layer forming the ground layer is continuously formed to be extruded to prevent contraction and expansion of the formed corrugated hole, as well as to prevent stretching and warping, and by an air spray holder configured to be coupled to the rear of the extrusion die. 360 ° blowing inside the mold and at the same time prevents air leakage by air packing, so it is possible to blow at low pressure, and the one side mold and the other mold are matched from the corrugated pipe formed by the anti-curling bar.
