Abstract

PURPOSE:To improve the quality of a name part, abrasion-proof and displaying a coloring agent by causing the colored rubber packed in the recessed groove to adhere integrally and in a projected shape to the surface of the rubber product to be molded. CONSTITUTION:The coloring agent of golden color is added into natural or synthetic rubber and is kneaded, whereby a golden rubber 1 is obtained. It is dipped in the solvent such as toluene, and is agitated, whereby it is caused to become like clay. Said rubber is packed in and fill the recessed groove 4 for a name provided in a bottom force 3 of a mold comprising top and bottom forces 2, 3 warmed at about 40 deg.C as normal temperature. The rubber 5 for molding a rectangular plate is inserted into the bottom force 3, after toluene has been evaporated, and then the top force 2 is placed on the bottom force 3 and they are closed. Then, the temperature of the mold surface is raised to 140-200 deg.C under pressure and the rubber is vulcanized. By mold release after the vulcanization, is released from the mold the product integrally molded with the rubber rectangular plate 5a of specified dimensions and the projected name part whose lower surface is made of the golden rubber.

After filling and evaporating the solvent, rubber for product molding is inserted into the mold for molding the product, and the colored rubber filled in the groove is molded by heat and pressure vulcanization. A method of forming a convex colored part on a rubber molded product by integrally protruding and attaching it to a non-defective surface.

できるものとなる。By demolding after vulcanization, a rubber square plate 5a of predetermined dimensions is formed.
A label 4a made of golden rubber is integrally molded in a protruding shape on the lower surface of the plate and then taken out.The above embodiments are examples in which a rubber rectangular plate and a label containing a coloring agent are protruded and molded on one side of the rubber square plate. As explained above, by pre-filling the groove that forms the name and this groove with colored rubber that has turned into clay, it is possible to create molds and molding methods for other rubber products (can be applied to watch bands, etc.). It is possible to protrude and mold names, patterns, etc. containing colorants on various rubber products such as camera cases from the plate body that makes up the product.
