An automobile weather strip includes an extrusion-molded portion and a die-molded portion. The die-molded portion includes: a mount base to be mounted on the periphery of the door; and a hollow seal integrally molded with the mount base and coming into elastic contact with the circumferential edge of a vehicle body opening. The mount base includes a bottom in the shape of a plate. The bottom has a core removal slit for removing a core, and the core removal slit extends in a longitudinal direction of the die-molded portion. The core removal slit has a length set shorter than the length of the core in the same direction. The bottom includes a thick-walled portion at a portion adjacent to an edge of the core removal slit. The thick-walled portion is thicker than the other portions of the bottom.

The weatherstrip includes a molded part formed from an elastic material and the molded part has an insert panel embedded therein. The molded part includes: a molded part through hole in which a clip for attaching the molded part to a vehicle body can be inserted; and a thinner portion provided in an outer peripheral portion of the molded part through hole and having a thickness smaller than that of other portions of the molded part in an area of the molded part where the insert panel is embedded in. The insert panel includes a clip through hole provided at a location corresponding to the molded part through hole and having a diameter larger than that of the molded part through hole; and a first additional through hole provided spaced from the clip through hole in an area corresponding to the thinner portion.

Weatherstrip

A door weather strip includes an installation base member and a main seal part. A die molded part on a corner part connects an extrusion molded part on a roof side and an extrusion molded part on a pillar side. An installation base member of the extrusion molded part on the roof side has a foam seal lip. An installation base member of the die molded part has a die molded seal lip connected to the foam seal lip by die molding. Thickness of the die molded seal lip is thicker in a range from a position on a straight part on a roof side of the die molded part to a position on a curve than in a range from a position of connection between the extrusion molded part on the roof side and the die molded part to the position on the straight part on the roof side.

There is provided a molded productwhich is formed by placing an insertin a molding spaceformed by an upper dieand a lower die, followed by an injection process of molding material to form a molded body. The insertis comprised of an insert bodywhich is embedded in the molded bodyand a removing partwhich is integrally formed with the insert bodyvia a thin partat one end while the other end is projected to expose at a non-front surfaceside. The removing partfunctions to prevent the insert bodyfrom moving from its proper position as the other end is firmly held between the upper dieand the lower dieduring a molding operation. The removing partis removed from the insert bodyby cutting the thin partafter released from the die mold.
