いた。2. Description of the Related Art A mixing head of a foam molding machine generally used as a raw material mixer for molding a phenolic resin foam is generally configured as shown in FIG. 2, and a raw material such as a resole and a curing agent is set in a cylindrical chamber a. An agent, a foaming agent and the like are respectively injected through the orifice b, and these are mixed and stirred by the rotor c to prepare a mixed solution necessary for foaming. In this type of apparatus, when the forming work is finished and the raw material supply to the chamber is stopped, the inner wall of the chamber, the orifice b,
The mixed liquid adheres to the rotor c and the like. If the mixed liquid is left to stand as it is, the mixed liquid foams and hardens and sticks, resulting in the inability to supply the raw material and the inability to rotate the rotor. . Therefore, in the conventional apparatus, the nozzle d is provided on the upper wall of the chamber, and the nozzle d is immediately provided after the molding work is completed.
Alcohol having a function of dissolving the mixed solution is injected into the chamber, and the rotor is rotated to wash the mixed solution.

開始するまでにかなりな時間がかゝっていた。Problems to be Solved by the Invention In the conventional device, the nozzle is provided on the upper wall of the chamber as shown in FIG. 2 so that alcohol is sprinkled downward from the nozzle. The top wall, corners, and orifices of the product are not sufficiently cleaned or not cleaned at all, and the mixed liquid remains as it is, and the foamed cured material is often accumulated and the orifice is clogged. It took me a long time to melt and start the next operation.
この考案はアルコール洗浄不良によるチャンバー上部壁
への混合液の付着及びオリフィスの詰り等を解消して上
記の問題を解消しようとするものである。This invention is intended to solve the above problems by eliminating the adhesion of the mixed liquid to the upper wall of the chamber and the clogging of the orifice due to the poor alcohol cleaning.

うにしたものである。Means for Solving the Problems Therefore, in the present invention, the cleaning liquid is made to flow directly from the upstream side of the orifice to directly clean the orifice, and a guide flow path is connected to the orifice so that the cleaning liquid flowing out of the orifice passes through the guide flow path and is placed in an appropriate position in the chamber. It is further discharged so that a dead space where the cleaning liquid does not reach does not occur in the upper part of the chamber.

る。That is, according to the present invention, a jig arranged in the upper part of the chamber is connected to the outlet of the orifice provided on the raw material supply line, and there is no step in the jig and the flow path of the orifice, and the cross-sectional area is smoothly continuous. Gradually expands to form a guide flow path with the outlet opening downward in the chamber and to bend and form the lower surface of the jig in which the guide flow path outlet is formed. A cleaning liquid supply line equipped with a valve is connected on the upstream side of the nozzle, and the cleaning liquid that is injected from the cleaning liquid supply line through the valve and flows out of the orifice is discharged into the chamber through the guide channel in the jig. It is what

Reference numeral 1 is a flange tubular mixing chamber, 2 is a housing fixed on the flange portion, and a plurality of flow paths 3 that bend downwardly from the peripheral surface in an elbow shape are symmetrically arranged in the housing at regular intervals in the circumferential direction. The flow path changing jig 4 formed in a fixed shape is fixed, and each flow path formed on the peripheral surface of the jig has its inlet connected to the orifice without any step, the cross-sectional area gradually increases, and the outlet bends in a concave shape. Of the cleaning liquid supply line 12 and the valve holder 6 is connected to each orifice by the orifice holder 7 and extends radially. The raw material is supplied to the orifice holder 7. A supply port 9 connected to the line 8 is formed in the radial direction, and a valve 11 is provided in the valve holder 6, and the valve 11 is always closed so that the raw material enters the cleaning liquid supply line 12. Cleaning liquid supply line 12 to the cleaning liquid after together has thus not stopping the supply of the raw material
When it is injected through, the pressure is opened so that the cleaning liquid flows into the orifice 5, is discharged downward from the flow path 3 of the jig 4, and hits the rotor 14 which is rotationally driven by the drive shaft 13. . Then, the cleaning liquid injected from the cleaning liquid supply line cleans the orifice holder 7, the orifice 5, the flow path 3 of the jig 4, the inner wall of the chamber 1, the rotor 14, etc., which form a part of the raw material supply line.

面を伝い落ち、残ることがないなどの効果を有する。Effect of the Invention As described above, according to the invention, the cleaning liquid is injected from the upstream side of the orifice, and the outlet of the orifice is connected to the jig disposed in the upper part of the chamber, and the flow path of the orifice is provided in the jig. A guide flow path is provided in which the step area gradually expands continuously without any step, and the outlet opening that expands downward in the flow path is opened on the curved jig lower surface. It is formed smoothly without any steps, and since there are no steps or corners, the cleaning liquid does not adhere to and remain in the guide flow path or the connection part with the orifice. Because of the expansion, the cleaning liquid diffuses from the outlet, the dead space where the cleaning liquid does not reach the upper part of the chamber does not occur, the cleaning can be performed reliably, and the lower surface of the jig in which the guide channel is formed is curved. In addition, the cleaning liquid does not easily adhere, and even if it adheres, it has the effect of not falling down along the curved surface and remaining.
