Method for manufacturing toothbrush marks, toothbrush with marks and marking mold

Abstract

The invention discloses a method for manufacturing toothbrush marks. The method comprises the steps that the marks are manufactured on a brush handle of a toothbrush body through a mold marker, wherein the marks are stereoscopic positive-energy words or sentence shapes or protrusions composed of English letters, the stereoscopic positive-energy words or sentences composed of the English letters contain a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z, A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y and Z, and the mold marker is manufactured through the laser engraving technology. The regular, designable and concave-convex stereoscopic characters with the high character fineness can be manufactured on the brush handle of the toothbrush through the mold marker, and the problems that single patterns or characters are arranged on the surface of the brush handle of the toothbrush, have no stereoscopic feeling and are likely to be aged in the prior art are changed.

Description

technical field [0001] The invention belongs to the technical field of toothbrush forming technology, and in particular relates to a method for making toothbrush marks, a marked toothbrush and a mark mold. Background technique [0002] Dental cleaning and health care is a daily homework for modern people. There are different opinions on how often people should brush their teeth at least every day. In principle, they should brush their teeth and clean their mouth after eating. And the food in the mouth, so as not to affect the health of teeth and oral cavity from the growth of bacteria. [0003] Although a wide variety of utensils are known for cleaning teeth and oral cavity, including toothbrushes, dental floss and floss picks, most people still use toothbrushes as the main utensil for cleaning teeth. The graphic and text marks of toothbrushes on the market are generally pasted on the handle with stickers. The brush handle made by this setting method is rigid in shape, easy...

AI Technical Summary

Problems solved by technology

The graphic and text marks of toothbrushes on the market are generally pasted on the handle with stickers. The brush handle made by this setting method is rigid in shape, easy to age and fade, has no three-dimensional effect, and lacks innovation; or use grooves on the toothbrush handle and then paste cartoon pattern marks in the groove. Although the pattern marks on the toothbrush handle of this structure are not easy to age and fade, they have no three-dimensional effect. If fonts are used, it is difficult to see clearly with the naked eye, and the aesthetics and delicacy are not good.

[0004] Nowadays, the commonly used domestic processing methods for setting characters or pattern marks on plastic or molds are through mechanical processing, such as processing through CNC machining centers; or making electrodes, processing with EDM, CNC processing cannot clear right angles or acute angles due to cutting tools, and thin walls part easily deformed

Moreover, molds with high hardness such as HRC60 or above are difficult to machine. The EDM production process is complicated. First, the corresponding electrodes are made, and then EDM electric discharge machining is performed. The cost is high and the cycle is long, and the characters or patterns obtained from the processing The edges and corners and the delicate effect are not good enough, which can no longer meet people's requirements for the precision of processed items to be more and more refined.

[0005] The working principle of the laser engraving machine is to irradiate the surface of the material with a high-energy laser beam, a small part of the laser is reflected, most of the light passes through the surface of the material, and is converted into heat energy in the material to heat the material. Due to the thermal effect of the material, the material Irradiated by a laser beam with sufficient power density to reach the melting and vaporizing temperature of the material surface, the material is vaporized or melted, and the required graphics and characters are engraved as permanent marks. With the development of industry, laser engraving machines are used for plastic or It is becoming more and more common to make graphics or text on the mold, but there is no report on its use for toothbrush marking, and there is no report on engraving high-precision positive energy fonts on toothbrush handles.
