That is, the extrusion molding machine nozzle structure according to the present invention includes a main nozzle that is attached to the tip of the extrusion molding machine and has a material passage formed therethrough with a shape corresponding to the desired molded product shape, and a main nozzle that is attached to the tip of the extrusion molding machine. It consists of a coating nozzle attached to the outside in an overlapping manner, and the coating nozzle has an opening slightly larger than the material passage formed therethrough, and has an opening corresponding to the desired liquid application area. A liquid discharge port is formed on the inner wall surface of the opening portion, and a wide fan-shaped liquid supply passage is formed inside the coating nozzle from the passage hole to the liquid discharge port, and further inside this liquid supply passage. It is characterized by being equipped with a flow rate control section to equalize the flow of liquid.

その際に、液吐出口から送り出される液、例えばコーテ
イング液や塗料が成形品表面に連続的に塗布される。The material plasticized inside the extruder is extruded through the material passage of the main die to form a molded product with a predetermined cross-sectional shape. The molded product extruded from the main nozzle then passes through the opening of the coating nozzle, but
At this time, a liquid, such as a coating liquid or paint, sent out from the liquid discharge port is continuously applied to the surface of the molded product.

As is clear from these figures, an opening 12, which is slightly larger than the material passage 9 of the main mouthpiece 5, is formed through the coating mouthpiece 6. In addition, at the application site of the coating liquid 35 described above, the inner wall surface 12a is precisely processed so as to have a slight step (approximately 0.5ff71) with respect to the inner wall surface 9a of the material passage 9. The shape of the portion has a considerably large margin with respect to the material passage 9. Furthermore, three through holes 13 are provided at a relatively upper portion of the applicator nozzle 6 to match the threaded holes 10 of the main nozzle 5, and three through holes 13 are provided at a relatively lower portion of the applicator nozzle 6. A positioning pin 14 that fits into the positioning hole 11 is implanted. The applicator cap 6 is positioned with respect to the main cap 5 by fitting the positioning pin 14, and then the three screws 15
They are fixed together as shown in FIG.

A groove-shaped liquid supply passage 17 extending from a passage hole 20 connected to the liquid supply pipe 16 to a desired liquid application area is recessed in the back surface of the coating nozzle 6 in the shape of a fan. .

。The liquid discharge port 18 at the tip of the liquid supply passage 17 opens into the inner wall surface 12a of the opening 12, as shown in FIGS. 1 and 6. Further, as shown in detail in FIG.
The flow rate control section 19 is formed shallower than the closer portion, and is provided here with a large number of grooves 19a' along the flow direction of the liquid. Note that the liquid supply pipe 16 is
Each is connected to a coating liquid supply device via a comb tube (not shown) or the like, so that a coating liquid made of urethane resin or the like is supplied at an appropriate pressure.

溝１９ａの深さ等を調整することによって、各液吐出口
１８からの吐出流量を簡単に調整することができる。In particular, in the configuration described in ``2'', there are a large number of grooves 1 in the liquid discharge port 18 portion.
．． Since the flow rate control unit 19 consisting of 9a is provided, the coating liquid can be uniformly supplied over the entire liquid discharge port 18, and as a result, the coating Tr! The coating thickness of i, 35 can be made uniform. That is, when one flow rate control section is not provided, the flow of the liquid that spreads out in a fan shape in the liquid supply passage 17 tends to be biased toward the center (section B in FIG. 7), and toward both sides (section B in FIG. 7). A
Although there is a possibility that the flow rate of the part) may decrease, the above configuration can prevent such imbalance in the flow rate. Moreover, by adjusting the depth of the groove 19a, etc., the discharge flow rate from each liquid discharge port 18 can be easily adjusted.

均一なものとすることができる。Next, FIG. 8 shows a different embodiment of the flow rate control section provided in the liquid supply passage 17. In this embodiment, a substantially diamond-shaped or hard-shaped protrusion 21 is formed in the center of the fan-shaped liquid supply passage 17, so that the coating liquid is positively guided to both sides by the protrusion 21.
The flow rate of the coating liquid flowing out from the liquid discharge port 18 can be made uniform in each part.

Note that the arc of the stepped portion 22 is convex toward the flow direction. In this embodiment as well, the flow of the liquid is bent to both sides due to the curvature of the stepped portion 22, so that the flow rate of the coating liquid discharged from the liquid discharge port 18 can be made uniform in each part.

In particular, it can be applied to the case where a liquid is applied to the inner circumferential surface of an extrusion molded product in the shape of a hollow tube.

となる利点もある。Effects of the Invention As is clear from the above explanation, according to the extrusion molding machine mouth structure according to the present invention, coating liquid or paint can be applied to the extrusion molding machine mouth part at the same time as extruding glass runs, weather strips, etc. Application can be carried out continuously. In particular, the flow rate control unit can uniformly discharge the liquid from the entire liquid discharge port, and even when the liquid application area is wide, uniform application is possible. Therefore, compared to the conventional case where coating is performed by spraying, the work process can be significantly simplified and equipment for spray coating is not required. Furthermore, it is possible to minimize the amount of coating applied only to the necessary areas, thereby preventing wasteful consumption of coating liquid and the like. Furthermore, when applied to partial coloring, there is an advantage that the boundary with non-colored parts becomes clear and masking is not necessary.
