Embodiment Construction

[0018] The present invention provides a silicone brush and its manufacturing method. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] The invention provides a method for manufacturing a silicone brush, wherein the silicone brush is obtained by extruding hot-melt silica gel in a cavity formed by a steel upper and lower template inlaid with a copper core, wherein the copper core is A plurality of tapered holes for forming brushes are provided. Each bristle of the silicone brush obtained by the above method is fully formed, and the product yield rate is obviously higher than that of the injection molding method.

[0020] Wherein, the copper core is detachably arranged on the steel upper formwork and ...

Abstract

The invention discloses a silica gel brush manufacturing method; a silica gel brush is obtained by extruding hot melting silica gel in a molding cavity formed by upper and lower steel templates embedded with copper cores, wherein multiple taper holes for forming the brush are formed in the copper cores. Copper core are embedded in a traditional steel mold; since copper is soft and easy to cut then steel, the problem of difficult machining of dense small mold holes is overcome; the corresponding mold machining difficulty is reduced; and the mold development cost is largely reduced. Meanwhile, the taper holes in the copper core are machined in a segmented manner to prevent the problem of easy break of a cutter, so that the mold opening success rate and the mold opening efficiency are improved, and the product quality of the machined silica gel brush is improved.

Description

technical field [0001] The invention relates to the technical field of silica gel product preparation, in particular to a silica gel brush and a manufacturing method thereof. Background technique [0002] At present, when processing products such as silicone brushes, it is difficult to use traditional steel molds to make small-diameter porous molds. The processing tools are easy to break, and the entire mold is likely to be scrapped because it is difficult to remove the broken blade after a certain aperture is broken, and thus As a result, the mold opening time of silicone brush products is long, and the mold opening cost is greatly increased. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a silicone brush and its manufacturing method, aiming at solving the problems of difficulty and high cost of mold openin...
