【考案の詳細な説明】
［考案の目的］
（産業上の利用分野）
この考案は、発泡スチロール成形において金型
の雌雄型に多数設けた供給孔に嵌込む噴射スリツ
トに関する。[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to injection slits that fit into a number of supply holes provided in male and female molds in styrofoam molding.
（従来技術）
これまで用いられている噴射スリツトには大別
して、前壁に多数の噴射孔を設けるとともに控部
を円筒状（即ち内部空間を有する容器状）に形成
したものと、所定幅の円柱の軸方向に多数の噴射
孔を貫設したものの二態様がある。(Prior art) The injection slits that have been used so far can be roughly divided into those that have a large number of injection holes on the front wall and have a cylindrical retaining part (i.e., a container shape with an internal space), and those that have a predetermined width. There are two types of cylinders with a large number of injection holes extending through them in the axial direction.
しかし前者には、控部の空間内にスチーム凝縮
水が溜まり、これによつて原料の詰り、充填不
良、密着性不良、発泡温度条件が阻害されるなど
の難点を生ずる。また後者は、凝縮水の問題は解
決するが透過性が劣化する難点を有する。 However, in the former case, steam condensed water accumulates in the space of the holding part, which causes problems such as clogging of raw materials, poor filling, poor adhesion, and obstructing the foaming temperature conditions. In addition, although the latter solves the problem of condensed water, it has the drawback of deteriorating permeability.
（本考案が解決しようとする問題点）
本考案は、従来のかかる実情に鑑みてなされた
もので、噴出孔およびそれに至る溝の形状に工夫
を凝らすことにより上記難点を解消したものであ
る。(Problems to be Solved by the Present Invention) The present invention has been made in view of the conventional situation, and has solved the above-mentioned difficulties by devising the shape of the ejection hole and the groove leading to it.
［考案の構成］
（実施例）
以下図面の実施例によつて説明すると、第１図
乃至第５図に示すように、１がスリツト本体で、
その前壁１ａに同心円状の噴出孔２を二条設け
る。[Structure of the invention] (Example) The following will be explained with reference to the embodiments shown in the drawings. As shown in Figs. 1 to 5, 1 is a slit main body,
Two concentric jet holes 2 are provided on the front wall 1a.
またその控部１ｂには前記噴出孔２に通ずる縦
溝３を二条設けて構成される。 Further, the retaining portion 1b is provided with two vertical grooves 3 communicating with the ejection holes 2.
［作用並びに効果］
今これを使用するには、第６図乃至第８図に示
すように、金型の雌型４、雄型５の各供給孔６に
本案スリツトを向合う方向に嵌込む。[Functions and Effects] To use this now, as shown in Figs. 6 to 8, insert the slits of the present invention into the respective supply holes 6 of the female mold 4 and male mold 5 of the mold in opposite directions. .
さて、その供給孔６から原料とともにスチーム
が噴射されるが、本考案にあつては前記のように
スリツト本体１の前壁１ａに同心円状の噴出孔２
が設けられ、またその控部１ｂに該噴出孔２に通
ずる縦溝３が設けられているから、スチームはそ
の縦溝３より効率的に同心円状噴出孔２に導か
れ、その各円状内周面に沿つて回流しつつ円滑に
噴射される。 Now, steam is injected together with the raw material from the supply hole 6, but in the present invention, the concentric jet hole 2 is formed in the front wall 1a of the slit body 1 as described above.
is provided, and since the longitudinal groove 3 that communicates with the jet hole 2 is provided in the retaining portion 1b, the steam is efficiently guided to the concentric circular jet hole 2 through the vertical groove 3, and the steam flows through each circular hole. It is smoothly injected while circulating along the circumferential surface.
従つて先に挙げた凝縮水の滞留による不都合を
解消し、品質の著しい向上を図ることができる。 Therefore, the above-mentioned inconvenience caused by the accumulation of condensed water can be eliminated, and the quality can be significantly improved.
