Abstract

PURPOSE:To make it possible to mold a corner part of a weather strip in a precise shape, by positioning and fixing a cut-left lip part at the belt-like part along the bottom when molded in a mold. CONSTITUTION:A solid rubber layer 330 of the outer side face of a lip part 33 of a weather-strip 3 is integrally extrusion-molded with a main body part of a sponge rubber. When a corner part A is molded, on the end of the weather strip 3, other part except the lip part 33 and a belt-like part 34 of the base part side along the giving-up line (a) is cut off. The end of the cut-off weather- strip 3 and the end of a weather-strip 4 are set in a mold 6 by holding them between a cavity for molding a corner To sel the lip part 33 of the weather-strip 3, the belt-like part 34 is fixed at a precise position by using molds 62 and 63 and the whole is thereby positioned. A mold 61 is set to close the mold and a sponge rubber is poured in the cavity. The precise position and shape of the lip part 33 are thereby ensured.

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for molding door weather strips, particularly corner portions thereof.

[Prior Art] A door weather strip for sealing between the door sash and the door opening of the vehicle body is attached to the door sash of an automobile.

As shown in FIG. 3, the door weather strip includes a mounting base 31 held on the outer periphery of the door sash 1;
A weatherstrip 3 is used that includes a hollow seal portion 32 that protrudes from the vehicle body and contacts the side edge 21 of the door opening of the vehicle body, and a lip portion 33 that extends upward from the base portion 31 and contacts the drip 22. This weather strip 3 is first extruded from sponge rubber.

By the way, since sponge rubber has a rough surface and lacks luster, a solid rubber layer 330 is formed on the outer surface of the lip portion 33 that appears on the outside as a design surface to improve the appearance.

On the other hand, when the weather strip 3 is installed along the door sash 1, it is attached to a corner of the door sash 1, for example, from the rear end of the upper side to the vertical part, so if the weather strip is bent at a right angle, the cross-sectional shape becomes large. Since the shape will be distorted, only the corner portions are first formed by molding.

[Problems to be Solved by the Invention] Conventionally, as shown in FIGS. 4 and 5, the above-mentioned molding has been performed using a weather strip 3 having a lip portion 33 having a solid rubber coating layer 330 on its outer surface. , the ends of another weatherstrip 4 connected to this through the corner part are set in a mold 6 in a direction that intersects at almost right angles, and the corner part A is molded by injecting sponge rubber between them.

However, in the corner portion A formed by this method, a clear difference in color tone appears at the boundary 5 with the lip portion 33 having the solid rubber coating layer 330, and the appearance is not good.

Therefore, as shown in FIGS. 6 and 7, the end of the weatherstrip 3 is cut off except for the lip portion 33 having the solid rubber coating layer 330, and the corner portion A is molded. It is taken. As a result, the entire design surface of the corner part becomes a solid rubber surface, which improves the appearance.

When setting the terminal with the lip portion 33 left in place in the mold 6, the remaining lip portion protrudes elongately and is unstable, making positioning difficult. It is divided into 61.62. However, even if the lip portion 33 is positioned accurately, twisting or protrusion may occur before the mold 61 is closed.
Since the displacement cannot be visually recognized after the mold 61 is closed and the mold 61 is closed, it often happens that molding is carried out with the displacement still in place.

Therefore, when molding the corner portion of a weatherstrip in which the outer surface side of the lip portion 33 is the designed surface of the solid rubber layer, the lip portion can be set in the mold without misalignment and with ease of work, and can be placed in the desired position. The purpose of this invention is to provide a method for molding a corner portion into an accurate shape, thereby solving the problems of the conventional method.

[Operation and Effect] During molding, the uncut lip portion 33 is positioned and fixed by the band-shaped portion 34 along its root. Therefore, even if there is twisting or the like in the elongated lip portion left uncut, the lip portion is firmly held at the base, so no deformation or displacement occurs, and the reliability of molding is greatly improved. As a result, a corner portion having a predetermined shape can be formed without variation for each product.
