Problems solved by technology

For smart wearable products, traditional watch straps are mostly monochrome, which makes it difficult to satisfy consumers' pursuit of product appearance
[0003] At present, although there are also two-color moldings for watch straps, the two-color molding process in the prior art has the following two methods: (1) separately molding two-color watch strap parts, and then applying a treatment agent and then hydraulically compounding them; The two-color molding method will cause glue bottlenecks and easily cause glue overflow; (2) The first color area is formed by hydraulic pressure once, and the second color raw material is formed by secondary hydraulic pressure; the secondary hydraulic pressure in this two-color molding method is easy to cause Extrusion deformation or glue overflow phenomenon

Abstract

The present invention relates to the technical field of electronic product accessories, in particular to a molding process of a two-color rubber watch strap, comprising the following steps: Step 1, one-time hydraulic molding; Step 2, deburring; Step 3, knife die punching; Step 4 1. Secondary hydraulic molding; Step 5, deburring; Step 6, 3rd hydraulic molding; Step 7, grinding; Step 8, spraying; Step 9, vulcanization and curing. The forming process of the two-color rubber watch strap uses a knife die to punch and shape the raw material of the second color, and the punched product with holes is put into the primary formed product for secondary oil pressure forming, and then the second color is formed. The raw materials of the two colors are put into the transfer groove of the tertiary molding mold, and the rubber covering of the lower half of the inner hole of the transfer molding is carried out to obtain a semi-finished product, which can avoid deformation in the extrusion hole, and can also avoid glue bottlenecks and glue overflow. Phenomenon.
