Description

Technical Field

[0001] This utility model relates to the technical field of cosmetic brush processing equipment, and in particular to a cosmetic brush head forming mold. Background Technology

[0002] The brush head is the core structure of a makeup brush, and its manufacturing process includes selecting bristles, shaping, and winding. The shaping process involves manually placing the bristles into a special mold cup and then using manual or machine vibration to shape the bristles at the bottom of the cup into a spherical structure. The outer tips of the bristles are then trimmed evenly.

[0003] In the above-mentioned mold cups, whether picked up by hand or by machine, insufficient vibration will result in some bristles not being able to fully fit against the bottom of the cup, causing the bristles to fold and bend, which increases the workload of trimming the bristle heads. Secondly, common mold cups have a straight cylindrical structure, which cannot be used with automated assembly equipment for bristle insertion.

[0004] To address the aforementioned issues, a mold for forming makeup brush heads is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a mold for forming makeup brush heads, which solves the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A cosmetic brush head forming mold includes a cup body, the inside of which is threadedly connected to a storage tube, and a vibration mechanism is provided around the bottom of the storage tube.

[0008] The vibration mechanism includes a bottom cover threaded to the bottom of the cup body, a support frame welded to the top of the bottom cover, a rebound ramp integrally formed at the top of the support frame, a spring column hinged to the vertical wall of the rebound ramp, and a striking ball hinged to one end of the bottom of the spring column.

[0009] Furthermore, the cup body has an inverted conical structure, a boss is formed on the top of the cup body, a retaining ring is formed at the bottom of the boss along the periphery of the cup body, and a cup lid is fastened to the top of the cup body.

[0010] Furthermore, the cup lid has a through-hole formed inside, and a recessed platform is formed in the inner wall of the cup lid. The inner wall of the recessed platform engages with the protrusion, and the bottom of the recessed platform abuts against the retaining protrusion.

[0011] Furthermore, the storage hole is aligned with the opening of the storage tube, the bottom of the storage tube is a spherical structure, and the gap between the outer wall of the spherical structure and the striking ball is 1mm.

[0012] Furthermore, the top of the storage tube is formed with an ear ring, which is movably engaged with the boss. Directly below the ear ring, there is a female thread formed with the outer wall of the storage tube, which is engaged with the male thread on the inner wall of the boss.

[0013] Furthermore, the striking ball is made of silicone, while the rebound ramp and the support frame are both made of metal.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] This invention incorporates a support frame, striking ball, rebounding ramp, and spring column within a traditional molded cup. When the cup is vibrated, the striking ball, spring column, and rebounding ramp form a continuous rebounding excitation source, continuously striking the outer spherical edge at the bottom of the receiving tube. This increases the vibration within the receiving tube, enhancing the effect of the external vibration source on the internal structure. It also causes the brush bristles within the receiving tube to vibrate and fall, improving the neatness of the bristle heads in the bottom spherical groove, reducing bristle bending and folding, and minimizing trimming work.

[0016] The cup body of this invention is an inverted cone with a variable diameter structure, which can be fixed and hung on the rotating mechanism of automated equipment, making it convenient to adapt to automated equipment for wool insertion operations and solving the problem of low efficiency in manual wool insertion operations of traditional straight cups.

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-5 As shown, this embodiment provides a cosmetic brush head forming mold, including a cup body 1. A storage tube 103 is threadedly connected to the inside of the cup body 1. A vibration mechanism 104 is provided on the bottom periphery of the storage tube 103. The vibration mechanism 104 includes a bottom cover 104a threadedly connected to the bottom of the cup body 1. A support frame 104e is welded to the top of the bottom cover 104a. A rebound inclined plate 104d is integrally formed at the top of the support frame 104e. A spring column 104c is hinged to the vertical wall of the rebound inclined plate 104d. A striking ball 104b is hinged to one end of the bottom of the spring column 104c.

[0026] In the above structure, both the bottom cover 104a and the storage tube 103 can be freely disassembled for easy maintenance, and the rebound slope 104d is made of metal plate.

[0027] The cup body 1 has an inverted conical structure. The top of the cup body 1 is formed with a boss 102, and the bottom of the boss 102 is formed with a retaining ring 101 arranged along the periphery of the cup body 1. The top of the cup body 1 is fastened with a cup lid 2. The inverted conical structure makes the cup body 1 a variable diameter structure. In the work station hole of the automated equipment, the cup body 1 can be hung on the assembly for rotation processing, which facilitates the wool feeding operation of the automated equipment.

[0028] The cup lid 2 has a through-hole 201 formed inside, and a recess 202 is formed in the inner wall of the cup lid 2. The inner wall of the recess 202 is engaged with the protrusion 102, and the bottom of the recess 202 abuts against the snap ring 101. The storage hole 201 is a flared structure that expands outward.

[0029] The storage hole 201 is aligned with the opening of the storage tube 103. The bottom of the storage tube 103 is a spherical structure. The gap between the outer wall of the spherical structure and the striking ball 104b is 1mm, leaving a 1mm space to facilitate the vibration and rebound of the striking ball 104b within this space, continuously striking the outer wall of the storage tube 103.

[0030] The top of the storage tube 103 is formed with an ear ring 103a, which is movably engaged with the boss 102. Directly below the ear ring 103a, there is a female thread 103b formed with the outer wall of the storage tube 103, which is engaged with the male thread on the inner wall of the boss 102.

[0031] The striking ball 104b is made of silicone, while the rebound ramp 104d and support frame 104e are both made of metal.

[0032] The working principle of this device is as follows:

[0033] When in use, the bristles enter the storage tube 103 through the storage hole 201 of the cup lid 2. The bottom of the bristles fits into the spherical cavity at the bottom of the storage tube 103. Then, by hand or machine, vibration is applied, and the bottom of the bristles falls off and fits into the spherical cavity, forming a spherical head shape.

[0034] During this process, the striking ball 104b, which has a 1mm gap with the outer wall of the spherical cavity of the storage tube 103, is subjected to external vibration. It is then springed by the spring column 104c and rebounds to the outer wall of the spherical cavity of the storage tube 103 after contacting the rebounding inclined plate 104d. This vibration and striking action increases the vibration of the inner wall of the spherical cavity of the storage tube 103, allowing the bristles inside to be fully shaken to the bottom, reducing the chance of folding and bending.

[0035] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
