【考案の詳細な説明】
本案はスライドコアを案内し、あるいは押えるための一
対の突出部を備えたスライド用駒を利用したものである
。[Detailed Description of the Invention] The present invention utilizes a slide piece provided with a pair of protrusions for guiding or pressing the slide core.
各図において、１は固定側取付板、２は固定側型板、３
，４は可動側型板、５はスライドコアである。In each figure, 1 is the fixed side mounting plate, 2 is the fixed side template, 3
, 4 is a movable template, and 5 is a slide core.
従来の第１図あるいは第２図のものにおいては金型開閉
にともなうスライドコア５の移動を案内するための傾斜
ピン６と、型締め時にすライドコア５が射出圧に耐える
ようにそれを押えるためのストッパー７を、別々に固定
側板２に取付けていた。In the conventional one shown in FIG. 1 or 2, there is an inclined pin 6 for guiding the movement of the slide core 5 as the mold is opened and closed, and a tilt pin 6 for holding the slide core 5 so that it can withstand injection pressure when the mold is closed. The stoppers 7 were separately attached to the fixed side plate 2.
本案はこの点改めたものである。This proposal has been revised in this respect.
これを第３図、第４図を用いて説明する。This will be explained using FIGS. 3 and 4.
８はスライド用駒で、そのスライドコア５側の面には一
対の第１突出部８１と第２突出部８２がそれぞれ一体に
立設され、その中間のところに取付孔８３が形成されて
いる。Reference numeral 8 denotes a slide piece, on the surface of which faces the slide core 5, a pair of first protrusions 81 and a second protrusion 82 are integrally erected, and a mounting hole 83 is formed in the middle thereof. .
９はスライド用駒８を固定型板２におけるスライドコア
５側の面に固定したボルトである。Numeral 9 is a bolt that fixes the slide piece 8 to the surface of the fixed mold plate 2 on the slide core 5 side.
一方の第１突出部８１はスライドコア５の受孔５１に入
り、第１突出部８１の傾斜面が受孔５１の側面に接する
状況下で、金型開閉時の摺動作用にともなってスライド
コア５を移動させる。One of the first protrusions 81 enters the receiving hole 51 of the slide core 5, and when the inclined surface of the first protruding portion 81 touches the side surface of the receiving hole 51, it slides during the sliding operation when opening and closing the mold. Move core 5.
受孔５１の長さは、その工作が容易なように第１突出部
８１の全長よりも短かく定めであるが、すライドコア５
の移動範囲は第１突出部８１の全長によって定められる
。The length of the receiving hole 51 is set to be shorter than the entire length of the first protruding portion 81 so as to facilitate its machining.
The movement range of the first protrusion 81 is determined by the entire length of the first protrusion 81 .
しかして、第１突出部８１の先が受孔５１がらはみ出す
ので、それを受けるための凹廊３１が可動側型板３に形
成されている。Since the tip of the first protrusion 81 protrudes from the receiving hole 51, a recess 31 for receiving it is formed in the movable mold plate 3.
もう一方の第２突出部８２には型締め時にスライドコア
５の一部をスライドコア５が移動しないように押え込み
、キャビティ１０内の射出圧に対してスライドコア５が
耐えるようにするための傾斜面が具備されている。The other second protrusion 82 has an inclination for holding down a part of the slide core 5 so that the slide core 5 does not move when the mold is clamped, and for the slide core 5 to withstand the injection pressure inside the cavity 10. Equipped with a surface.
以上のように、本考案はすライドコア案内用がつ押圧用
の一体製のスライド用駒を利用したものである。As described above, the present invention utilizes an integral slide piece for guiding the slide core and pressing the slide core.
したがって、部品点数が少なく、またそれをまとめて同
時に取付けることができるので、金型全体のコストが低
減する。Therefore, the number of parts is small, and since they can be assembled and installed at the same time, the cost of the entire mold is reduced.

の突出部を示す。1 and 2 are respectively sectional views showing conventional molds, FIG. 3 is a sectional view showing the mold of the present invention, and FIG. 4 is an enlarged perspective view showing the sliding piece in FIG. 3. In the figure, 2 is the fixed side template, 3 and 4 are the movable side templates, 5 is the slide core, 8 is the sliding piece, 81 and 82 are the first and second
The protrusion is shown.
