【発明の詳細な説明】
（産業上の利用分野）
この発明は型締装置の下方から金型の交換を可能とする
横型の射出成形機に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a horizontal injection molding machine that allows molds to be replaced from below a mold clamping device.
（従来の技術）
横型の射出成形機における金型の交換は、型締装置の上
方から行う場合と側方から行う場合とがあり、それらは
特公昭５Ｂ−１８８９９号公報や特公昭５６−１９２５
１号公報により既に公知となっている。(Prior art) In a horizontal injection molding machine, there are two types of mold replacement: one is done from above the mold clamping device, and the other is done from the side.
It is already known from Publication No. 1.
（発明が解決しようとする問題点）
金型交換を上方から行う場合の問題点は、重量のある金
型を吊り上げて空中を搬送するため、地上を搬送する場
合に比べて、搬送装置を堅牢に作る・必要があり、それ
につれて装置が複雑となって大型となり易く、屋内に充
分な設置空間が必要となるなどの問題があった。(Problem to be solved by the invention) The problem when changing molds from above is that the heavy molds are lifted and transported in the air, so the transport device must be more robust than when transporting them on the ground. As a result, the device tends to become more complex and large, and there are problems such as the need for sufficient installation space indoors.
また側方から交換を行う場合には、上方からの交換のよ
うな問題点はないが、射出成形機の側部に金型搬送機器
などが設置されるため、射出成形機だけの場合に比べて
据付面積が増大し、床面積に限りのある所では射出成形
機の据付台数が減少することがあった。In addition, when replacing from the side, there are no problems like replacing from above, but mold conveying equipment is installed on the side of the injection molding machine, so compared to when only the injection molding machine is used. This increases the installation area, and in places with limited floor space, the number of injection molding machines installed may decrease.
また射出成形機と搬送装置とが別体となっていることか

ブレートの間隔を決めなければならないなど手間を要す
る。In addition, since the injection molding machine and the conveyor are separate, the height difference between the two must be considered during installation, and the mold is transferred from the conveyor to the mold clamping and loading side. The method used to do this is different from the one used for hanging, and in order to accurately set the mold in the predetermined position of the mold clamping device,
Rollers for transferring the mold must be installed with high accuracy on the side of the mold clamping device, and when transferring the mold, the spacing between the guide plates must be carefully determined so that the mold does not fall off the rollers. It takes time and effort.

記昇降シリンダ７を作動して、型締装置から外された金
型４を搬送器５の上に降す。When replacing the mold 4 set in the mold clamping device 3 with another mold, when the mold 4 is pre-temperature-controlled, operate the lifting cylinder 7 to remove the mold from the mold clamping device 3. The removed mold 4 is lowered onto the carrier 5.
また金型４の取外しは、予めピストン７ａを伸長して先
端のテーブル７ｂにより金型４を支えながら行う。Further, the mold 4 is removed while the piston 7a is extended in advance and the mold 4 is supported by the table 7b at the tip.
搬送器上に降された金型４は、温調位置に待機した交換
用金型が、昇降シリンダ７の位置に搬送されるとき、同
時に機台１の搬出口へと送り出される。The mold 4 that has been lowered onto the carrier is sent out to the exit of the machine 1 at the same time as the replacement mold that has been waiting at the temperature control position is transported to the position of the lifting cylinder 7.
この金型の交換は、所定量の成形品の完了ごとに行うこ
