Description

本考案は固化押出成形装置に係り、詳しくは溶融軟化した熱可塑性合成樹脂に 背圧をかけつつ、フォーマ内で板状に展開、賦形したのち冷却固化する固化押出 成形装置に関する。 The present invention relates to a solidification extrusion molding apparatus, and more particularly, to a solidification extrusion molding apparatus that applies back pressure to a molten and softened thermoplastic synthetic resin, expands and shapes it into a plate in a former, and then cools and solidifies it.
【０００２】[0002]
従来、樹脂特に結晶性樹脂を溶融押出しつつ溶融軟化樹脂をフォーマ内で背圧 下に冷却して所定形状に賦形する固化押出装置においては、フォーマの上型及び 下型の内側には溶融樹脂の入口側から冷却固化する出口側に亘り、比較的厚手の 内面を平滑加工した一枚板からなる鋼板をボルト固定して使用していたが、設備 の大型化に伴ない重量の増大と相まって磨き加工費、旋盤加工費等が顕著に増加 すると共に、厚手の鋼板であるが故に熱伝達効率が悪く、特に冷却には長時間を 要するなど、エネルギーの損失が大きいと云う問題があった。 Conventionally, in a solidification extruder that melt-extrudes a resin, particularly a crystalline resin, and cools the melt-softened resin under a back pressure in a former to shape it into a predetermined shape, the molten resin is placed inside the upper and lower molds of the former. From the inlet side to the cooling and solidifying outlet side, a steel plate consisting of a single plate with a relatively thick inner surface smoothed was used by fixing with bolts, but with the increase in size of the equipment, the weight increased. In addition to the significant increase in polishing processing costs and lathe processing costs, the heat transfer efficiency was poor due to the thick steel plate, and in particular, cooling took a long time, resulting in a large energy loss.
【０００３】 また、熱可塑性合成樹脂のうちで特に溶融流動性の少ない樹脂、融点の高い樹 脂、或いは比熱が大きい樹脂などを押出成形する場合に、上記成形装置では生産 性が低く、コストアップは脱がれなかった。Further, when a resin having a particularly low melt fluidity, a resin having a high melting point, or a resin having a high specific heat is extruded among the thermoplastic synthetic resins, the productivity is low and the cost is increased by the above molding apparatus. Didn't come off.

本考案は、上記課題を解決するための取付具であって、その要旨は熱可塑性合 成樹脂を押出機より溶融押出しつつ溶融樹脂に背圧をかけて賦形固化する成形装 置であって、押出機にアダプタを介して連設するフォーマの上型と下型の内壁面 に、鏡面仕上面を内側にして薄鋼板を付設したことを特徴とする固化押出成形装 置である。 The present invention is a fixture for solving the above-mentioned problems, and its gist is a molding device for shaping and solidifying a thermoplastic synthetic resin by an extruder to apply back pressure to the molten resin to shape and solidify it. The solidification extrusion molding device is characterized in that thin steel plates are attached to the inner wall surfaces of the upper and lower molds of the former, which are connected to the extruder via an adapter, with the mirror-finished surface facing inward.

以下、図面に基づき本考案を具体的に説明する。図１は本考案の実施例を一部 省略側面図で示す。 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing a part of the embodiment of the present invention.
【０００６】 本考案は図１に側面図で示す如く、押出機１にアダプタ２を介して連設するフ ォーマ３の上型３３及び下型３４の内壁面に、鏡面仕上面を内側にして厚みが２ 〜３mm程度の薄鋼板５を付設した成形装置である。As shown in a side view of FIG. 1, the present invention has a mirror-finished surface on the inner wall surface of an upper mold 33 and a lower mold 34 of a framer 3 connected to an extruder 1 via an adapter 2. This is a forming apparatus provided with a thin steel plate 5 having a thickness of about 2 to 3 mm.
【０００７】 即ち、上記フォーマ３は押出機１側に加熱フォーマ３１を配設し、該加熱フォ ーマ３１に接続して後方に冷却フォーマ３２を配設してあり、加熱フォーマ３１ は、上型３３と下型３４の各々の内壁面に、薄鋼板５の鏡面仕上面を各々内側に した状態で側縁部を側板３５の上下に挟み込み、固定具３６により上型３３、下 型３４間を締付け固定する。That is, in the former 3, a heating former 31 is arranged on the side of the extruder 1, and a cooling former 32 is arranged behind the heating former 31 so as to be connected to the heating former 31. On the inner wall surfaces of the mold 33 and the lower mold 34, the side edge portions are sandwiched above and below the side plate 35 with the mirror-finished surface of the thin steel plate 5 inside, and a fixture 36 is provided between the upper mold 33 and the lower mold 34. Tighten and fix.
【０００８】 図１の実施例では、加熱フォーマ３１において、上型３３、下型３４の各々の 内側に板体４を介しボルト締結して薄鋼板５を付設し、冷却フォーマ３２におい て、板板４を介さずに薄鋼板５を加熱フォーマ３１から冷却フォーマ３２に亘り 連設したものを例示したが、これに拘束されず必要に応じてフォーマ３の全長に 亘り薄鋼板５を連設してもよい。In the embodiment of FIG. 1, in the heating former 31, a thin steel plate 5 is attached to the inside of each of the upper die 33 and the lower die 34 through the plate body 4 by bolts, and the thin plate 5 is attached to the cooling former 32. Although the thin steel plate 5 is continuously provided from the heating former 31 to the cooling former 32 without interposing the plate 4, the thin steel plate 5 is continuously provided to the entire length of the former 3 as needed without being restricted by this. May be.
【０００９】 本考案によって、押出機１からアダプタ２を通り、加熱フォーマ３１に溶融導 入される樹脂Ａは、加熱フォーマ３１内で引取機によりブレーキ背圧を受けなが ら板状に展開しつつ賦形されるが、この賦形段階において、上型３３及び下型３ ４の内面に付設されている薄鋼板５及びその鏡面仕上面により、樹脂温度を熱伝 導効率よくコントロールできると共に、加熱フォーマ３１に引続く冷却フォーマ ３４においても、冷却効率よく円滑に賦形固化されて、生産性よく成形板体Ｂが 得られる。According to the present invention, the resin A which is melted and introduced from the extruder 1 to the heating former 31 through the adapter 2 is spread in the heating former 31 into a plate shape while receiving a brake back pressure by the take-up machine. However, in this shaping step, the resin temperature can be controlled with good heat transfer efficiency by the thin steel plate 5 attached to the inner surfaces of the upper die 33 and the lower die 34 and the mirror-finished surface thereof. Also in the cooling former 34 subsequent to the heating former 31, the shaped plate body B can be obtained with good productivity by smoothly shaping and solidifying with good cooling efficiency.
