【考案の詳細な説明】
本考案は熱硬化性樹脂あるいは熱安定性の悪い熱可塑性
樹脂等の成形を行う射出成形機の急冷装置に関する。[Detailed Description of the Invention] The present invention relates to a quenching device for an injection molding machine that molds a thermosetting resin or a thermoplastic resin with poor thermal stability.
射出成形機における加熱シリンダ内の樹脂は先づホッパ
等から供給された後、スクリュの移送作用により前方（
ノズルの方向）へ送られる。The resin in the heating cylinder of an injection molding machine is first supplied from a hopper, etc., and then transferred to the front (
(in the direction of the nozzle).
その間、前記樹脂は加熱シリンダの外側面に設けられた
加熱装置からの熱を受け、あるいはスオリュ回転による
摩擦熱を受けて溶融され、温度調節装置により一定温度
を維持するように制御されている。During this time, the resin is melted by receiving heat from a heating device provided on the outer surface of the heating cylinder or by frictional heat due to rotation of the heating cylinder, and is controlled to maintain a constant temperature by a temperature control device.
しかし、何等かの事故によりあるいは成形運転が終了し
、機械の運転が停止したときには加熱シリンダ内の樹脂
が熱硬化性樹脂あるいは熱安定性の悪い熱可塑性樹脂等
では、一定時間以上に加熱シリンダ内に逗るので加熱シ
リンダ、スクリュ等の残留する熱のため、硬化反応や分
解が起きる。However, if the resin in the heating cylinder is a thermosetting resin or a thermoplastic resin with poor thermal stability, if the resin in the heating cylinder is a thermosetting resin or a thermoplastic resin with poor thermal stability, the resin in the heating cylinder may remain in the heating cylinder for a certain period of time when the machine stops operating due to some kind of accident or when the molding operation ends. Because of the residual heat from heating cylinders, screws, etc., hardening reactions and decomposition occur.
いそのため硬化樹脂の場合には機械の再運転が不可能と
なり、また熱安定性の悪い樹脂の場合にはその分解によ
るガスのためスクリュやシリンダの腐食を起すこともあ
る、そのため機械の運転を停止した場合には、ノズルや
スクリュ等を素早く掃除し、加熱シリンダ内に樹脂が残
らないようにするのが通常である。This makes it impossible to restart the machine in the case of hardened resins, and in the case of resins with poor thermal stability, the gas from decomposition may cause corrosion of the screws and cylinders. When the heating cylinder stops, it is normal to quickly clean the nozzle, screw, etc. so that no resin remains inside the heating cylinder.
このことは非常に面倒なことであり、かつノズルやスク
リュ等を傷つけやすい。This is very troublesome and is likely to damage the nozzle, screw, etc.
本考案は前述のような欠点を取除き、機械の運転が停止
した場合でも加熱シリンダ内を樹脂が熱硬化や熱分解を
起さないようにすることであり、さらに詳しく本考案に
ついて述べると、加熱シリンダの加熱装置に液体あるい
は圧搾空気等を冷媒とする急冷装置を設は機械の運転が
停止し、一定時間が経過すると、前記急冷装置に前記冷
媒が流れるようにして加熱シリンダを急冷するようにし
た装置である。The purpose of this invention is to eliminate the above-mentioned drawbacks and to prevent the resin from thermally curing or thermally decomposing inside the heating cylinder even when the machine stops operating.To describe this invention in more detail, A quenching device using liquid or compressed air as a refrigerant is installed in the heating device of the heating cylinder, and when the machine stops operating and a certain period of time has elapsed, the refrigerant flows through the quenching device to rapidly cool the heating cylinder. This is a device designed for
次に第１図および第２図により説明すると１は加熱シリ
ンダで複数個のヒータ２により加熱される。Next, referring to FIGS. 1 and 2, a heating cylinder 1 is heated by a plurality of heaters 2. In FIG.
３は冷却用ジャケットで内部に冷却用の液体や圧搾空気
等の流体を流体源４から矢印のように電磁開閉弁５を介
して導入され、循環出来るようになっている。Reference numeral 3 denotes a cooling jacket into which a cooling liquid, compressed air, or other fluid is introduced from a fluid source 4 via an electromagnetic on-off valve 5 as shown by the arrow, and can be circulated.
前記電磁開閉弁５は第２図の電気展開図に示すように機
械の運転が停止された後、所定時間が経過すると作動す

内を循環するようになり、シリンダ１およびスクリュ９
が冷却される。As shown in the electrical development diagram in FIG. 2, the electromagnetic on-off valve 5 operates when the timer 6, which is set to operate after a predetermined period of time has elapsed after the operation of the machine is stopped, times out, and the relay 7 operates. The contact point 7A is connected, the solenoid 8 of the electromagnetic on-off valve 5 is energized, and the circuit from the fluid source 4 to the cooling jacket 3 is opened, allowing fluid to flow into the jacket 3.
It now circulates inside cylinder 1 and screw 9.
is cooled.
従って当初に掲げたような欠点が取除かれ、加熱シリン
ダ１やスクリュ９に残っている熱のため、熱硬化や熱分
解が起きない、尚１０は流量調整用の弁で、前記ジャケ

ある。Therefore, the drawbacks listed at the beginning are eliminated, and thermal curing and thermal decomposition do not occur due to the heat remaining in the heating cylinder 1 and the screw 9. Furthermore, 10 is a valve for adjusting the flow rate, and the valve 10 is a valve for adjusting the flow rate, This adjusts the amount of cooling fluid introduced.
