Description of the Related Art As a device for manufacturing a window molding attached to a front window of an automobile, a cross-sectional shape in which the thickness of a head of an upper portion gradually expands upward as approaching a side portion through a corner portion. In addition, there has been disclosed a method in which the upper portion and the side portion are continuously and integrally extruded so that the depth of the cutout of the rainwater receiving groove is gradually increased as approaching the side portion (for example, Japanese Patent Application Laid-Open No. HEI 9-1997). 174658).

As shown in FIG. 6, a fixed die 100 and a first die 101 for forming a main body of a molding are used.
And a second die 102 for forming a rainwater receiving groove, and the first die 101 approaches or separates from the extrusion molding port 104 side (moves in the vertical direction in FIG. 6) by the rotation of the drive motor 101a, The second die 102 has a drive motor 102a
With the rotation of, it approaches or moves away from the extrusion opening 104 side (moves right and left in FIG. 6).
By changing the shape of the extrusion opening 104 by moving the first die 101, the cross-sectional shape of the head of the window molding is changed from the upper portion to the corner portion and to the side portion. A rainwater receiving groove is formed on the head.

First Embodiment FIG. 1 is a front view showing a window molding manufacturing apparatus according to a first embodiment of the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. From the state of FIG.
FIG. 6 is a front view showing a state where the die 11 is lowered and the second die 12 is moved to the left.

This apparatus for manufacturing a window molding is mainly for mounting on a front window of an automobile and continuously extruding a window molding from an upper portion to a side portion through a corner portion while changing its cross-sectional shape. An apparatus, comprising: a fixed die 10 having a flat plate shape arranged in the XY plane; a first die 11 having the same flat shape stacked on the plane of the fixed die 10; and a second die further stacked on the plane of the first die 11. A first die 12 and a first die 11 that are movable in the X direction (the vertical direction in FIG. 1).
A first motor 13 is provided as a driving device, and a second motor 14 is provided as a second driving device that allows the second die 12 to be movable in a substantially Y direction (left-right direction in FIG. 1). A hydraulic or pneumatic cylinder may be used instead of the motors 13 and 14. The motors 13 and 14 are connected to the first die 11 and the second die 12 by joints 15 and 16, respectively.

The XY plane may be a horizontal plane or a vertical plane, but in this embodiment, it is defined as a vertical plane. Fixed die 1
0, an opening 2 having a shape corresponding to the maximum value of the cross-sectional shape of the window molding and mainly including a head forming portion 21 and a leg forming portion 22 and having no rainwater receiving groove formed therein.

The liquid is continuously discharged in a direction (horizontal direction in the present embodiment: a direction from the back surface to the front surface in FIG. 1). Here, the shape corresponding to the maximum value of the cross-sectional shape of the window molding refers to the cross-sectional shape of the maximum value of the side portion of the window molding, and at this time, the corner portion is cut off at the upper portion, rounded on the curve, and The head forming part 21 is the largest (the state shown in FIG. 1).

The first die 11 is slidably movable in the X direction (vertical direction) so as to close the opening 20.
The shape of the opening 20 can be changed from at least a fully open state corresponding to the side part (FIG. 1) to a half open state corresponding to the upper part (FIG. 3). That is, below the first die 11 in the X direction, there is formed an extending portion 11a which protrudes downward and extends.
And a substantially inverted "" -shaped curve 11b constituting the contour of the maximum value of the cross-sectional shape of the head of the window molding is formed along the base of the extension 11a.
When the first die 11 is slightly lowered in the X direction, the shape of the head forming portion 21 of the opening 20 is cut off from above by the curved portion 11b of the first die 11, and by further lowering the first die 11, the curved portion 11b becomes As shown in FIG. 3, the opening 20 is in a half-open state. As a result, the extruded molding whose head gradually changes from the maximum head to a small one is formed.

The second die 12 is fixed by a guide 26 so as to be slidable substantially in the Y direction (left and right directions), and intersects with the opening 20 to form a closed area for forming a rainwater receiving groove, ie, synthetic resin or heat. The portion where the molding material such as a plastic elastomer is not discharged is formed from the periphery of the opening 20 toward the inside. Here, as shown in FIG. 2, the base 12 a of the second die 12 is overlapped with the fixed die 10, but the tip 12 is a portion forming the straight rainwater receiving groove R.

Is not blocked by the second die 12,
The first die 11 does not prevent the movement of the die 12.

Therefore, the sectional shape is deformed by the movement of the first die 11 and the rainwater receiving groove R is formed by the movement of the second die 12.
Is formed at the same time without a lime lag. For example, when the window molding of the upper portion having a constant cross-sectional shape is changed to the side portion, the rainwater receiving groove R is formed from the start portion of the change of the corner portion. As a result, it is possible to form a long-looking rainwater receiving groove R as shown in FIG. 7B.

The tip of the extension 11a is connected to the opening 2
Even when the first die 11 is moved to a position where the shape of 0 is fully opened (the state shown in FIG. 1), the opening 20 is positioned closer to the leg forming portion 22 than the head forming portion 21 of the opening 20. It is. According to this, since the tip of the extension portion 11a is always located closer to the leg portion forming portion 22 than the head forming portion 21 of the opening 20, no streak or mark is formed on the head of the window molding. There is an advantage that the appearance is further improved.
