のヒレ基部70上に流れ込むこととなる。In the conventional molding method as shown in FIGS. 4 to 7, the fin base portion 71 of the molding portion M is flush with the fin base portion 70 of the extrusion molding portion. Since the groove 20 for close fitting of the fin base portion 70 of the lower mold 10 has the same cross-sectional shape through the molding die, the cut line xx of the extrusion molding portion varies and the cut base portion is formed. If the protruding dimension a of 70 is not uniform, the connecting surface between the end surface E 1 or E 2 of the extrusion-molded portion and the die-molded portion M does not follow the set shape, or, for example, the dimension a becomes smaller than the set value. In this case, a gap is formed between the bottom surface of the groove 20 of the lower mold and the cut surface 8, and the molding material flows into the fin base 70 of the extrusion molding portion during molding.

The present invention provides a novel molding method that does not affect the molding even if the protrusion dimension a varies.

As shown in (A) and (B), the lower mold 1 is a conventional lower mold (FIG. 4).
On the other hand, only the shape of the groove 2 has a new structure. That is, the lower mold 1 is formed with a groove 2 for inserting the fin base portion 70 of the weather strip in the longitudinal direction, and one end face mounting reference line l 1 -l 1 of the weather strip of this groove 2 is formed. The distance D between the other end surface mounting reference line l 2 and l 2 is equal to the vertical partition wall 2
The groove is buried via E and 2E. The other middle dies, middle plates and upper dies have the same construction as the conventional example.

After a predetermined length is cut with, the one end surface E 1 and the other end surface E 2 of the weather strip are line l 1 -l 1 and line l 2 of the lower mold 1.
Aligned on -l 2, i.e., the partition wall 2 an end surface of the fin base 70
Set in a form of contacting with E and positioning, and projecting the fin bases 70 at both ends into the groove 2 of the lower mold 1,
After setting the middle mold, the middle plate, and the upper mold on the lower mold 1 and clamping the mold, a molding material is injected into the cavity formed on the space D of the lower mold 1 to mold both ends E 1 of the weather strip. , E

い。If the cut lines xx of the fins 7 at both ends of the weather strip are set in accordance with the intermediate reference line L between the bottom surface 2a and the top surface 2b of the groove 2 of the lower mold 1, the cuts of the fins 7 will vary. Even if there is, there is a problem that the cut surface 8 of the fin base 70 is caught by the groove bottom portion 2a to form a gap between the mounting surface s of the weather strip body 5 and the mounting portion 3 of the lower mold 1,
The occurrence of any one of the problem of forming a gap between the end surface of the fin base 70 and the partition wall 2E of the groove 2 can be maintained at the minimum probability. That is, the cut surface 8 may theoretically be located below the top surface 2b and above the bottom surface 2a.

A fin strip 70 is formed by cutting off the fins 7 protruding from the mounting surface s of the weather strip body 5 along the cut surface 8. That is, at the position (xx) protruding from the placement surface s defined by the line FF by the dimension a, the fin 7
When the present invention is applied to a cut piece (FIG. (A)), mold forming without a fin base can be achieved as shown in FIG. (B), and the same effect as Example 1 can be achieved.

きが発生しても型成形には何の影響も出ない。The fin base portion 70 of the weather strip has a shape protruding into the groove 2 more than the upper surface 2b of the groove 2, and the fin base portion
Since the end surface of 70 is injection-molded with the partition wall 2E of the groove 2 set in contact with it, the flow of the molding material into the extruding part can be completely prevented, and the cut line xx of the fin 7 varies. If it occurs, it has no effect on the molding.

の型成形方法。1. A lower mold (1) is provided with a groove (2) for inserting a fin base (70) of a weather strip, and one end surface of the weather strip is placed on the groove (2). The distance (D) between the reference line (l 1 -l 1 ) and the other end surface placement reference line (l 2 -l 2 ) is set to the groove (2) through both partition walls (2E, 2E).
Embedded in the weather strip, and cut the fins (7) on both ends of the weather strip with a line (xx) protruding from the placing surface (s) of the weather strip body (5) by a dimension (a). To form the fin base (70) and then each fin base (7
The end surface of (0) is brought into contact with both partition walls (2E, 2E) of the groove (2) so that both end surfaces (E 1 , E 2 ) of the weather strip are respectively placed on the mounting reference line (l 1 -l 1 , l 2 −l 2 ), the fin base (70) is set in the lower mold (1) so as to project into the groove (2), and then the middle mold, the middle plate and the upper mold are arranged in the lower mold (1). A method for molding a weatherstrip, in which a material is injected into a cavity formed on a space (D) between both end surfaces of the weatherstrip after the material is placed on the molds and the molds are clamped to connect both ends.
