としている。Hitherto, as this type of window frame gasket type automobile weather strip, one having the structure shown in FIGS. 1 and 2, for example, has been known.
The IJ knob is located at 7 of body panel 1 as shown in Figure 2.
272 part 1 a* i b K The flange lip 2 that is fitted to and clamps the window glass 3, the outer and inner glass lips 4a and 4b that are fitted to and clamps the window glass 3, and the body panel 1 that is elastic. Consisting of the contacting outer lip 5 and cushion lip 6, etc., the straight general part is formed by extrusion molding, but the corner part other than the - general part is formed by upper and lower type type separately from extrusion molding as shown in Fig. 3. The weather strip is molded using a mold M, whereby the entire weather strip is shaped like a frame.

低下して水洩れ誘発の原因になるという問題がある。By the way, when performing the above-mentioned mold molding, it is necessary to set an injection gate for injecting the rubber dough at a required position in the corner molding area, and this injection gate 7 is shown in Fig. 3. When it is set near the base of the cushion lip 6 as shown in FIG. Although this gate remaining portion 7a is finally cut by a cutting machine, etc., due to variations in the cutting condition, a part of the product may be cut, or a part of the product may be cut off.
11Q Extra portion 7a remains partially and uncut portion 7
If b exists (FIG. 2), there is a problem in that it reduces sealing performance and causes water leakage.

を形成したことを特徴としている。In view of the above-mentioned points, the present invention has been made for the purpose of making it easier to cut off the remaining portion of the gate, and also to prevent a deterioration in sealing performance due to the remaining portion of the gate being left uncut. For this purpose, in the present invention, a gate residual portion serving as an injection gate is formed at a part of the base corner of the cushion lip that comes into elastic contact with the body panel, and the vicinity of this gate residual portion is made larger than other portions. It is characterized in that it is recessed to be one step lower and that a narrowed portion is formed at the base of the remaining gate portion so that the remaining gate portion can be easily separated.

In a corner part 0 of the IJ knob, that is, in a part of the corner of the cushion lip 6 that comes into elastic contact with the body panel 1 as described above, an injection gate 7 serving as a fK rubber fabric injection port is set at a position corresponding to the base of the cushion lip 6. A gate residual portion 7a is integrally formed at the base of the cushion lip 6, and a circular concave portion 8 is formed near the base of the gate residual portion 7a, whereby the vicinity of the gate residual portion 7a is connected to other parts. It has a single depression so that it is one step lower than the other.

うまでもない。Here, the corner part ○ is molded by die molding separately from the extrusion molding of the straight general part as described above, but in this case, the entrance gate 7 of the mold M is
As shown in FIG. 9, a protrusion 10 corresponding to the concave portion 8 and a protrusion 11 corresponding to the narrowed portion 9 are provided. Incidentally, since the remaining gate portion 7a is completely useless as a product, it goes without saying that it will ultimately be cut and discarded.

い。Therefore, according to the above configuration, since the narrowing part 9 exists, the gate remaining part 7 can be removed using scissors or the like as in the past.
Instead of the cutting operation in step a, the remaining gate portion 7a can be easily separated by simply pulling the remaining gate portion 7a.
In addition to making the work extremely simple, variations in the cutting state are eliminated and the cutting becomes uniform. Moreover, even if an uncut portion 7b is generated as shown in FIG. 8 when cutting the remaining gate portion 7a, the narrowed portion 9 is set so as to fall within the depth h range of the recessed portion 8. Therefore, the top of the uncut portion 7b is the cushion lip 6.
The weatherstrip does not protrude beyond the outer surface of the weatherstrip, and even if some uncut portion 7b exists, this does not affect the sealing performance of the weatherstrip in any way.

は水洩れを未然に防止できる効果がある。As is clear from the above description, according to the present invention, a gate residual portion serving as an injection gate is formed at the base of a part of the corner of the cushion lip, and the vicinity of this gate residual portion is recessed so as to be one step lower than the pond portion. At the same time, by forming a narrowed part at the base of the gate remaining part, it is sufficient to simply pull the gate remaining part when cutting the gate remaining part, which makes the cutting operation extremely easy. Uniformity can be achieved by eliminating variations in . In addition, according to the present invention, even if there is some uncut portion when cutting the remaining portion of the gate, the narrowed portion itself is set to fit within the concave recess, so that the uncut portion is removed from the cushion lip. It does not protrude from the outer surface of the gate, which has the effect of preventing sealing failure and water leakage caused by uncut portions of the gate.
