Introduction to Cosmetic Silicone Wax and the Manufacturing Method of a Vacuum Release Device for Wax-based Cosmetics Production

Apr 19, 2021

Background technique:
Cosmetics and skin care products are commonly used products for modern women. Appropriate makeup can help women have a better appearance and vitality, and enhance their self-confidence. There are many types of cosmetics, which can be classified according to the object of use or the part of use, or according to the production process. At present, the current cosmetics production license in my country is classified according to the latter, which is divided into general liquid unit, cream and emulsion unit, powder unit, and gas. Spray and organic solvent unit, wax-based unit, toothpaste unit and other units. The wax-based unit refers to cosmetics with wax as the main base material, such as lipstick, lipstick, eyeliner, etc.

Regarding this type of wax-based cosmetics, there are two common production methods, one is the filling method, and the other is the filling method. The filling method is to pour the hot melt paste into the mold, take out the upper mold after cooling, insert the lipstick tube, and then draw the mold; the filling method is to directly place the lipstick tube back into the hot melt paste, and draw directly after cooling. The production efficiency of the filling method is higher than that of the filling method, and it is also the more common lipstick production method at present.

However, in the process of filling and producing lipstick, how to separate the molded and cooled paste from the mold while keeping the paste intact is a problem that needs to be overcome. In addition, today's lipstick not only pays attention to the product's own material, but also has many changes in appearance. Concave and convex patterns may be set on the paste, which increases the difficulty of separating the paste from the mold.

The Chinese utility model patent with the patent number 20072002170.9 discloses a lipstick mold. A plurality of silicone forming molds are assembled on a fixed frame, and a demolding mechanism is correspondingly provided below the silicone forming mold. There is a chamber for the corresponding accommodating of the silicone molding mold, and the side of the chamber and the bottom of the chamber are respectively provided with suction holes and blowing holes; thus, the suction holes can be firstly pumped to make the silicone mold molds. Expand so that the silica gel forming mold is completely separated from the lipstick strip poured into it, and when air is blown into the silica gel forming mold from the blow hole, the lipstick strip can be smoothly pushed to the upper lipstick box base to be combined. The technical effect achieved by the utility model patent is to effectively prevent the uneven pattern formed on the surface of the lipstick strip from being scratched during the lipstick manufacturing process.

However, in the above-disclosed technical solution, a plurality of holes are provided in the demolding mechanism for air extraction, the mold setting is not simple enough, and multiple air extraction devices need to be connected externally, and the efficiency is limited.

Technical realization elements:
The purpose of the utility model is to overcome the above shortcomings of the prior art and provide a vacuum release device for wax-based cosmetics production. The release device has a simple structure and high production efficiency. At the same time, it can effectively prevent wax-based cosmetics such as lipstick from being released. Surface abrasion caused by the process, mass production of wax-based cosmetics with concave and convex patterns on the surface.

In order to solve the above technical problems and achieve the above technical effects, the technical solution adopted by the present invention is: a vacuum mold release device for wax-based cosmetics production, which is characterized in that it includes a perfusion cavity, a silicone mold, and a vacuum cavity;

The pouring cavity is provided with a plurality of molding holes inside, and the bottom end of the molding hole is provided with a through hole penetrating the pouring cavity;
The silicone mold is placed in the molding hole to match the size of the molding hole;
The vacuum cavity is movably embedded with the bottom end of the filling cavity, and the cavity is provided with a vacuum connection hole which penetrates the inside and outside of the cavity and is connected with a vacuum pump.

In the production process of wax-based cosmetics, the silicone mold is placed in the molding hole of the casting cavity, and then the wax-based raw material is poured into the silicone mold by hot melt. After the wax hot-melt-based raw material is cooled and formed, the casting cavity is vacuumed. The cavities are embedded and connected to the vacuum pump through the vacuum connection hole of the vacuum cavity. After the vacuum pump is started, negative pressure is formed in the vacuum cavity, and through the through hole at the bottom of the forming hole, the inner wall of the forming hole also forms a negative pressure, The outer wall of the silicone mold in contact with the molding hole and the inner wall in contact with the wax-based raw material form an air pressure difference, which separates the silicone mold from the wax-based raw material, and can easily take out the processed wax-based raw material without abrading the patterns on it. .

Further, the perfusion cavity further includes an inverted trapezoidal clamping position, the inverted trapezoidal clamping position is located at the bottom of the perfusion cavity and can be embedded in the vacuum cavity, and the upper part of the inverted trapezoidal clamping position is a clamping position. The inverted trapezoidal card position makes the fitting and sealing of the filling cavity and the vacuum cavity better, and at the same time reduces the space in the vacuum cavity, improves the working efficiency of the vacuum pump, and makes each silicone mold and the processed molding The wax-based raw materials are separated more quickly.

Furthermore, the clamping position is clamped to the vacuum chamber. The buckling position relative to the trapezoidal buckling position makes the vacuum cavity and the pouring cavity better fit and tightly, and improves the vacuum efficiency.

Further, the length of the silicone mold is higher than the depth of the molding hole. This makes the two ends protrude when placed in the molding hole, which can be turned down and fixed on the pouring cavity, which facilitates the separation of the silicone mold in a vacuum state.

Furthermore, the inner wall of the silicone mold is provided with concave and convex patterns. The concave-convex pattern can form a pattern on the surface of the wax-based raw material during the cooling process of the poured hot-melt wax-based raw material.

The beneficial effect of the utility model is to provide a vacuum release device for wax-based cosmetics. The release device has a simple structure and high production efficiency. At the same time, it can effectively avoid the surface caused by wax-based cosmetics such as lipsticks during the demolding process. Abrasion, mass production of wax-based cosmetics with concave and convex patterns on the surface.
