Description
【0015】
【発明の実施の形態の使用方法】
次に発明の実施の形態の使用方法を説明する。
初めに、運転開始のための操作、即ち、液体循環路に液体を充填する操作につき説明する。
開閉弁80は閉じておく。また、流量調節弁30は少し開けておく。
その状態で、開閉弁38、第1開閉弁54、第2開閉弁49を開くと、液体供給源43から液体が開閉弁38、フロート室11を経て、液体循環路に供給される。
なお、液体循環路内の空気は、フロート室11、第1開閉弁54、第2開閉弁49を通って、排液管51より排出される。そして、ほぼ液体循環路内に液体が満たされると、上記の状態のまま液体循環用ポンプ71を作動して、液体を空気と共に排液管51より排出する。
そして、フロート15が上下動しなくなったことをもって液体循環路に液体が充填されたことを知る。
その後、第1開閉弁54、第2開閉弁49を閉じる。なお、開閉弁38は開いたままで保持する。[0015]
[Method of using the embodiment of the invention]
Next, how to use the embodiment of the invention will be described.
First, an operation for starting operation, that is, an operation for filling the liquid circulation path with liquid will be described.
The on-off valve 80 is closed. In addition, the flow control valve 30 is slightly opened.
In this state, when the on-off valve 38, the first on-off valve 54, and the second on-off valve 49 are opened, liquid is supplied from the liquid supply source 43 to the liquid circulation path through the on-off valve 38 and the float chamber 11.
The air in the liquid circulation passage is discharged from the drainage pipe 51 through the float chamber 11, the first on-off valve 54, and the second on-off valve 49. Then, when the liquid circulation path is substantially filled with the liquid, the liquid circulation pump 71 is operated in the above state to discharge the liquid together with the air from the drainage pipe 51.
Then, the fact that the liquid circulation path is filled with liquid is known from the fact that the float 15 has stopped moving up and down.
Thereafter, the first on-off valve 54 and the second on-off valve 49 are closed. The on-off valve 38 is held open.

次に金型26の交換について説明する。
まず、液体循環用ポンプ71・棒状のヒーター67・射出成形機を非作動状態とした後、開閉弁38をあけたままの状態で、第1開閉弁54、第2開閉弁49を開き、開閉弁80を開く。
そうすると、パージエアーが、金型26を経て液体と共に排液管51より排出される。なお、その際、液体循環路から排出される液体に液体供給源43からの常温の液体が混合されるので、液体循環路から排出される液体を冷却しつつ排出することが出来る。そして、所定時間後に開閉弁38を閉じ、更にパージを行なう。
なお、液体循環用ポンプ71や往路導管6内の液体は完全には抜けないが、それは逆止弁24の作用によって金型26を交換する際における支障とはならない。
その後、金型26を交換する。[0018]
Next, replacement of the mold 26 will be described.
First, after the liquid circulation pump 71, the rod-like heater 67, and the injection molding machine are inactivated, the first on-off valve 54 and the second on-off valve 49 are opened and opened while the on-off valve 38 is open. Open the valve 80.
Then, purge air is discharged from the drainage pipe 51 together with the liquid through the mold 26. At this time, since the normal temperature liquid from the liquid supply source 43 is mixed with the liquid discharged from the liquid circulation path, the liquid discharged from the liquid circulation path can be discharged while being cooled. Then, after the predetermined time, the on-off valve 38 is closed and the purge is further performed.
Although the liquid in the liquid circulation pump 71 and the liquid in the forward conduit 6 does not completely escape, the action of the check valve 24 does not hinder the replacement of the mold 26.
Thereafter, the mold 26 is replaced.
