となつている。An example of a conventional resin injection device will be described with reference to FIG.
As shown in FIG. 3, a liquid curing agent 1 and a liquid main resin, that is, a main agent 2 and a solvent 3 contained in each of the containers 11 to 13 are used, and these are respectively a hardener valve 4 and a main agent valve.
5. Open the solvent valve 6 to connect to the resin mixing device 8.
Then, the resin mixing device 8 stirs the injected material by the mixing motor 7 and injects the mixed material into the mold 9 from the outlet. The controller 10 electrically controls the valves 4 to 6 and the motor 7 in accordance with an operation procedure described later.
次に動作について第４図のフローを参照して説明する。Next, the operation will be described with reference to the flow of FIG.

の溶剤３によつて樹脂混合装置８の内部を清掃できる。First, when the resin injecting device starts operating, both the curing agent valve (V 1 ) 4 and the main agent valve (V 2 ) 5 are opened by the electric signal output from the controller 10, and the solvent valve (V 3 ) 6
Is closed. As a result, the curing agent 1 and the main agent 2 are delivered into the resin mixing device 8 (step 30). At the same time, an electric signal output from the controller 10 causes the mixing motor (M) 7 to rotate to stir the injected material (see the same paragraph 3).
1). Therefore, the mixture of the curing agent 1 and the main agent 2 is injected and injected into the mold 9 from the outlet of the resin mixing device 8 (32).
At the end of operation, the hardener valve (V 1 ) 4 and the main agent valve (V 2 ) 5 are closed by an electric signal from the controller 10, and the solvent valve (V 3 ) 6 is now opened. . As a result, the solvent 3 is delivered into the resin mixing device 8 (see
3) Similarly, the mixing motor 7 is rotated by an electric signal output from the controller 10. Therefore, the solvent 3 is discharged from the outlet of the resin mixing device 8 together with the mixture remaining inside, that is, the already mixed agent (the same 34, 35), and the inside of the resin mixing device 8 can be cleaned by this solvent 3. .

Both the hardener valve (V 1 ) 4 and the main agent valve (V 2 ) 5 are opened by the electric signal output from the controller 10 (step 20). As a result, the curing agent 1 and the main agent 2 are delivered into the resin mixing device 8. At the same time, the mixing motor (M) 7 is rotated by the electric signal output from the controller 10 to stir the injected material (21). Therefore, the mixture of the curing agent 1 and the main agent 2 is injected and injected into the mold 9 from the outlet of the resin mixing device 8 (22). At the end of the operation, the hardener valve (V 1 ) 4 is closed and the main agent valve (V 2 ) 5 is opened by an electric signal from the controller 10. As a result, only the main agent 2 is delivered into the resin mixing device 8 (at 23), and the mixing motor 7 is rotated by the electric signal similarly output from the controller 10 to perform stirring.
