【考案の詳細な説明】
この考案は射出成形に用いるスライドコアの型
締め装置に関するものである。[Detailed Description of the Invention] This invention relates to a mold clamping device for a slide core used in injection molding.
従来のスライドコアの型締め装置は第１図示の
ように、スライドコア１，２の型締め板３はスラ
イドコアの上部だけを型締めしている。しかし長
尺物の成形の場合はスライドコアも長くなるの
で、上部を型締めしても下部は射出圧力により開
き、バリが出やすいという欠点があつた。 In the conventional slide core mold clamping device, as shown in the first figure, the mold clamping plates 3 of the slide cores 1 and 2 clamp only the upper part of the slide core. However, when molding a long item, the slide core also becomes long, so even if the upper part is clamped, the lower part opens due to the injection pressure, making it easy for burrs to form.
この考案はこうした従来技術における欠点を解
決するためのものである。 This invention is intended to solve these drawbacks in the prior art.

押すものである。 Next, examples will be described. In Figs. 2 to 4, a mold clamping plate 5 is fixed to the mounting plate 4, and the mold clamping plate is provided with a recess 10 in which the upper parts of slide cores 6, 7, 8, and 9 having tapered surfaces on the outside engage. It is being This mold clamping plate 5 is provided with angular pins 11, 12, 13, and 14, and these angular pins are inserted into the holes of the slide core so that they can move forward and backward, and when the mold clamping plate 5 rises, the angular pins also rise, and the slide core opens. . Push rods 15, 16, 17, and 18 facing downward are fixed to the mold clamping plate 5. A presser plate 23 is provided on the movable template 19 on 20 and 21. This presser plate 2
3 has a hole 24 having an inclined inner circumferential surface in contact with the outer tapered surface of the slide cores 6, 7, 8, and 9.
is open. The above push rods 15, 16, 1
Reference numerals 7 and 18 are for pushing the presser plate 23 downward against the spring.

ていく。 When molding a molded product, when the mold clamping plate 5 is lowered as shown in the second figure, the push rods 15, 16,
The presser plate 23 is also pushed down by 17 and 18. When the mold clamping is completed, as shown in the third diagram, the upper parts of the slide cores 6, 7, 8, and 9 are clamped by the mold clamping plate 5, and the lower parts of the slide cores are also clamped by the presser plate 23. In other words, mold clamping is performed at two locations, upper and lower. After molding is completed, by raising the mold clamping plate 5, the mold clamping of the upper part of the slide core by the mold clamping plate 5 is released, and since the push plate 23 is also raised by the springs 20 and 21, the lower part of the slide core is also lifted. When opened, the slide core opens laterally by the angular pins 11-14.
