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 method for manufacturing a silica gel brush. The silica gel brush is obtained by extruding hot-melt silica gel in a cavity formed by a steel upper and lower template embedded with a copper core, wherein the copper core is provided with A plurality of tapered holes for forming brushes. The present invention adopts the method of inlaid copper core in the traditional steel mould, utilizes the characteristics that copper is softer than steel and can be cut easily, overcomes the problem of difficult processing of small holes in dense molds, reduces the processing difficulty of corresponding molds, and the cost of mold development is correspondingly greatly increased reduce. At the same time, the taper hole on the copper core is processed in sections to avoid the problem of easy breakage of the tool, improve the success rate and efficiency of mold opening, and the product quality of the processed silicone brush is also 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...
