トの製造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing plastic elements by injection molding. More specifically, the present invention relates to a method for manufacturing a plastic element having a right-handed or left-handed helical wing of a predetermined width that divides the interior of the scissor tube into at least two halves within a hollow cylindrical tube.

時間を要するといり欠点があった。Conventionally, when manufacturing an element having a spiral row that divides the inside of the bud tube into a hollow cylindrical tube, a right-handed or left-handed spiral array is individually injection molded, and then the spiral row is injected into a hollow cylindrical tube. Because the pipe is manufactured by inserting and gluing or welding, there is some gap between the inner wall of the pipe and the spiral blade. Another drawback is that adhesion or welding requires a great deal of labor and time.

! The injection mold for manufacturing is constructed as described above.
An example of manufacturing a plastic element of the present invention using this molding die is as follows.
先ず可ｍｓｍ板３、ストリッパプレート４及びコア６が
固定ｇＡ型板２に密着すると、図示されていないが成型
機ノズル９より溶解樹脂が樹脂流入路７％ランナーｌＯ
を通ってキャビティ８に流入する。First, when the flexible msm plate 3, stripper plate 4, and core 6 are brought into close contact with the fixed gA mold plate 2, the melted resin flows from the molding machine nozzle 9 (not shown) into the resin inflow path 7% runner lO.
It flows into the cavity 8 through.

ッパプレート４を分離する。After the resin molded product in the cavity 8 is cooled and solidified, the rotating mold 3, the stripper grating 4, and the core 6 are separated from the fixed mold 2. Thereafter, the # side template 3, core 6 and stripper plate 4 are separated.
この時コア６は可動側型板３に連動して螺旋翼の捻り方
向と逆方向に回転しながら成型品から分ａする。その後
ストリッパプレート４に密着している成型品を取り出す
。At this time, the core 6 is separated from the molded product while rotating in a direction opposite to the twisting direction of the spiral blade in conjunction with the movable mold plate 3. Thereafter, the molded product that is in close contact with the stripper plate 4 is taken out.
この実施例では螺旋翼ｔ９０ｏ捻っ九角度になっている
