られている。2. Description of the Related Art Conventionally, an extrusion type coating apparatus has been widely used because it can perform uniform thin film coating. As the die head used in this coating apparatus, various types of die heads in which the tip portion of the die head is detachable from the die head body and can be replaced are available. That is, when the tip portion of the die head is worn by pigments or the like and becomes streaked, it is removed and replaced with another die head tip portion that has already been polished, or another die head tip portion of an arbitrary shape. Is to be replaced. In many types of die heads, as shown in FIG. 1, a die head tip portion 1 mainly contacts a die head main body 2 at one joint surface a and is fixed by bolts 3 in a direction perpendicular to the contact surface. In addition, the joining portion is provided with a portion to be joined at a point P such as a corner other than the joining surface a.

Since the die head tip portion 1 is fixed to the die head main body 2 by the bolts 3 in this contact state, the force F acts in the direction shown in FIG. There is a problem that the part 1 cannot be attached with high accuracy. Also,
Since there is provided a portion in contact with a point P such as a corner other than the joining surface a, there is also a problem that the die head tip portion 1 cannot be accurately attached due to a coating liquid or the like that cannot be sufficiently removed.

In particular, the angle with respect to the center line is 45 degrees. Most preferred.

る。FIG. 3 is a side view showing an example of a die head according to the present invention. As shown in the figure, this die head has a die head tip portion 11 which is a die head main body 1.
2 is a type that can be separated and exchanged.
By loosening and removing the die head tip portion 11, the die head tip portion can be freely replaced with another polished die head tip portion or another die head tip portion having an arbitrary shape. In addition, S in the figure is a slit portion serving as an outlet of the coating liquid.

問題はない。As shown in FIG. 4, the die head tip portion 11 and the die head main body 12 are symmetric with respect to the center line x of the bolt 13 parallel to the center line of the die head itself, and the angle α with respect to the center line x is 45 degrees. The two contact surfaces b and c are in contact with each other, and are fixed by bolts 13 in this state. Thus, the two joining surfaces b and c symmetric with respect to the center line x
As a result, the position accuracy of the die head distal end portion 11 can be easily obtained. Further, as can be seen from the definition of the plane stress, when the die head tip portion 11 is attached to the die head main body 12, the force F acts only in the direction parallel to the bonding surfaces b and c, so that the distortion generated in the die head main body 12 is minimized. In addition, the position accuracy of the die head tip portion 11 does not deteriorate. Note that the angle α with respect to the center line x is most preferably mechanically 45 degrees, but there is no practical problem if the angle α is about 45 degrees.

ない。Further, as shown in the figure, a chamfered portion 14 is provided near the intersection of the joining surfaces b and c in the die head tip portion 11 so that there is no portion other than the joining surfaces b and c that comes into contact at a point like a corner. is there. Eliminating the point-to-point contact portion in this way prevents the application accuracy of the die head tip 11 from deteriorating due to a coating liquid or the like that has not been sufficiently removed.
