Technical Field

The invention relates to an auxiliary vulcanization shaping method and device for a special-shaped automobile sealing strip, and belongs to the technical field of automobile product manufacturing.

Background

As shown in fig. 3 and 4, when the special-shaped automobile sealing strip is extruded, because the downward radian of the lap of the automobile sealing strip 8 is large, the supporting rib 7 is required to support the automobile sealing strip 8 during extrusion so as to assist in vulcanization molding of the sealing strip. However, this approach can present two problems: 1. the supporting ribs 7 are non-product structural members, the supporting ribs 7 need to be torn off after extrusion and vulcanization are completed, and the workload of extrusion line personnel is increased; 2. the torn support ribs 7 have no use value, are discarded as waste products, cause an increase in manufacturing cost, and pollute the environment.

Disclosure of Invention

The invention aims to provide an auxiliary vulcanization shaping method and device for a special-shaped automobile sealing strip, which are labor-saving, material-saving, low in manufacturing cost and capable of ensuring product quality, and overcomes the defects in the prior art.
