By injecting resin into (q), a molded product of a predetermined shape (r
), and move the movable mold platen (m) in the opposite direction to obtain mold (p) rate (n) and ejecting rod (・〕)
(u) is extruded in the same direction, and the molded product (r) is placed in the mold (p).
It is designed to be taken out from the
第2図は成形品(r)が押出された状態を示している。FIG. 2 shows the molded article (r) in an extruded state.
成形品の取出しは人手、自動取出し装置あるいは自動落

い落下できない。The molded product can be taken out manually, by an automatic take-out device, or by automatic dropping, but automatic dropping takes the shortest time. In automatic dropping, the extruded molded product is allowed to fall as it is, but in FIG. 2, when the molded product (r) falls, it interferes with the ejecting rod (u) and gets caught, so it cannot fall.
また人手あるいは自動取出し装置による場合でも、第2

Since the molded article (r) must be moved that much more to avoid the ejecting rod (u) shown in the figure, it takes longer to take out the molded article (r). As mentioned above, in the conventional method, tJy
, when taking out the molded product (r), the molded product (r) protrudes.
- Since it interferes with page U), it cannot be dropped automatically, and it takes extra time to take it out manually or automatically.
従来射出成形機は、単一の押出し装置しか持っていなか
ったため、成形品の取出し上様々の問題があり、金型内
の押出し機構を工夫することにより伺とかカバーしてき
た。そのため、金型構造が複雑になり、コスト高となる
欠点があった。Conventional injection molding machines had only a single extrusion device, which caused various problems in ejecting the molded product, and these problems were overcome by devising the extrusion mechanism inside the mold. Therefore, there was a drawback that the mold structure became complicated and the cost increased.
本発明は前記従来の欠点を解消するために提案されたも
