Description

【発明の詳細な説明】 この発明は芯材人押出成形品製造装置に関する。[Detailed description of the invention] The present invention relates to an apparatus for manufacturing core extrusion molded products.

従来、補強芯の埋入された無機質押出成形品を製造する
場合、無機質混練物成形ダイ内に押出方向に沿わせて芯
材を挿入し、もって成形ダイ吐出時に上記芯材が成形体
内に埋入された状態となって押出されるようにして製造
することが行われる。Conventionally, when manufacturing an inorganic extrusion molded product with a reinforcing core embedded, the core material is inserted into the inorganic kneaded material molding die along the extrusion direction, and the core material is embedded in the molded product when the molding die is discharged. Manufacture is performed by extruding the product in a state in which it is placed in a container.

しかしながら、上記芯材は押出成形品と共に押出方向に
沿って連続した状態であるから、製品とする場合、所定
長さ毎に切断する必要があり、この切断時に芯材に張力
が加わり、成形品の型崩れを生じさせ、後に整形を必要
とするといった欠点があった。However, since the core material is continuous along the extrusion direction along with the extrusion molded product, it is necessary to cut it into predetermined lengths when making it into a product. The disadvantage was that it caused the body to lose its shape and required plastic surgery later.

即ち、押出直後の成形体はそれ自身の保形性は有するが
、他の外力が加われば容易に変形し得る塑性状態にあり
、従って芯材を切断す°る際に、芯材に加えられるせん
断力に原因して、芯材が引張られたり、あるいは偏位し
たりすると、これに伴って、成形体が変形するといった
問題があった。In other words, the molded product immediately after extrusion retains its own shape, but is in a plastic state that can easily deform if other external forces are applied to it. When the core material is pulled or displaced due to shear force, there is a problem in that the molded article is deformed accordingly.

従来、このような問題を解消するため、例えば一定長さ

となどが行われていたが、上記いずれの場合も製造ライ
ンを一旦停止しなければならない、手作業を必須とする
など効率が悪く、自動的な大量生産には向かないといっ
た欠点があった。Conventionally, in order to solve this problem, for example, after extruding a molded product to a certain length, the extrusion molding was temporarily stopped, and the reinforcing core material was artificially cut off near the tip of the molding die using a convenient device such as pliers. Or, alternatively, a core material cut in advance to a certain length is artificially fed into the molding die, and on the other hand, for the extruded molded product, the interrupted part of the core material is visually measured and cut with a cutter. However, in all of the above cases, the production line had to be temporarily stopped, manual work was required, and the efficiency was low, making it unsuitable for automated mass production.
