題であった。(Prior Art) In various extrusion moldings using plastics, more or less dust-like substances such as impurities are attached to the front surface of the die, and with time, the attachment of the dust-like substances increases and carbonizes. The carbide is eventually attached to the molded product and removed. In the wire coating, the carbide may impair the appearance and cause spark out. Generally, as a method for removing the eye blemishes, a method of kneading an additive or the like, or a method of burning off using a gas burner, etc.,
It is a problem that it is difficult to completely remove it, it has not been solved yet, productivity is poor, and there are drawbacks such as high cost.
（考案が解決しょうとする課題） 本考案はこれらの欠点を解消したものであり、ダイ先端
に滑性液状物を塗布することにより、目やにを防止で

供するものである。(Problems to be solved by the invention) The present invention solves these drawbacks, and by applying a slippery liquid material to the tip of the die, it is possible to prevent the eyes and eyes, and to carry out extrusion molding efficiently and economically. To provide a die for use.

る。(Means for Solving the Problem) In the present invention, the front surface of the die is formed in a conical portion 2 having an angle of 45 ° ± 10 °, the thickness 1 of the die tip is 1 mm or less, and the outer periphery of the conical portion is smooth. A die for extrusion molding, which is covered with a cloth-like material 3 for impregnating a liquid material having properties.
（作用） 本考案は、ダイ先端の厚み１を1mm以下にし、45°±10

により目やにの発生を防止する。(Operation) The present invention reduces the thickness 1 of the die tip to 1 mm or less and 45 ° ± 10
The cone-shaped portion 2 is cut, and the outer periphery of the cone-shaped portion 2 is covered with a cloth-like material 3 which is easily impregnated with a liquid material such as felt, and a liquid material such as silicone oil or a surfactant having a smoothness is used as the liquid material. The dripping oiler 4 or the like is dropped onto the cloth-like material 3, the liquid material is induction-coated on the die tip, and the die tip is mirror-finished to prevent the generation of eye and eye.
ダイ先端の厚みが1mm以上あると目やにの付着面積が大
きくなり、成形品に対して目やにの発生が大きくなる。
従ってダイ先端の厚みを1mm以下にすることによって目

により液状物が滴下されているので目やには除去され、
従って成形品に対しての目やにの発生は防止される。こ
の円錐状の角度が55°以上の傾斜だと液状物の流れが速
くなり液状物が過剰となり、35°以下の傾斜だと液状物
の流れが遅くなり効果がなくなってくる。If the thickness of the die tip is 1 mm or more, the area of adhesion to the eye and eye will be large, and the eye and eye will be large on the molded product.
Therefore, if the thickness of the tip of the die is less than 1 mm, the area of adhesion to the eye area will be reduced. Furthermore, the shape of the front surface of the die will be a cone with an angle of 45 ° ± 10 °, preferably 45 ° ± 5 °. Is removed from the eyes and
Therefore, it is possible to prevent the occurrence of eyes and eyes on the molded product. If the conical angle is inclined at 55 ° or more, the flow of the liquid substance becomes fast and the liquid substance becomes excessive, and if the angle is less than 35 °, the flow of the liquid substance becomes slow and the effect is lost.
（考案の効果） 本考案の押出成形用ダイを使用すると、ダイ先端に滑性
鏡面被膜が形成されるので、従来ダイ前面に付着増加し
ていた目やには発生しても微量で成形品と共に流れるの
で、目やには増大せず防止できるので、外観が良好な成
形品を効率良く成形することができる。(Effect of the device) When the extrusion molding die of the present invention is used, a slippery mirror surface film is formed on the tip of the die, so even if it is generated on the eyes and the surface of the die that had been increased in the past, it will flow with the molded product in a minute amount Therefore, since it can be prevented without increasing the size of the eyes, a molded product having a good appearance can be efficiently molded.
