Description

{TWO-COLOR CORE MOLD OF COSMETIC TOOL}

The present invention relates to a core material molding die for a cosmetic container, and more particularly, to a core material molding die for a cosmetic container, wherein a core material molding hole is divided into two parts inside the movable die facing each other, The mold is subjected to secondary molding by the moving mold at the home position returning position of the moving mold after the primary molding by the fixed mold so that the two parts can be manufactured in different colors and different components along the longitudinal direction of the core, The present invention relates to a mold for molding a tocolor core material having excellent productivity and productivity as well as improvement in merchantability and functionality.

In general, a cosmetic tool having a stick-shaped core can be used without tools such as a tip or a brush, and is being developed in various forms such as a lipstick, a stick-shaped lip balm, a foundation, a blusher, a highlighter and a sun stick.

Since the core material of such a conventional cosmetic material is manufactured by pouring the cosmetic raw material into the cavity of the mold, and then molding and cooling the cosmetic material, the core material can be manufactured with only a single color and a single component, I could not increase it.

For this reason, a variety of techniques have been disclosed for manufacturing a core material of a cosmetic tool in multiple colors as well as for manufacturing multiple components.

First, in Patent No. 10-1304933, a core pin is inserted into an upper shaping mold and a first lower shaping mold to form a primary outer lipstick, and then, in an upper shaping mold and a second lower shaping mold, A core lipstick of a dual structure having an outer lipstick outside the inner lipstick by molding the lipstick is formed so as to form different components and different colors

However, since the core has different components and different colors to the inside and the outside, internal lipstick is not well recognized outside the core, so that consumers can not perceive it as a multicolor. Also, Problems.

Since the two-stage molding is performed by combining the upper molding die and the second lower molding die separate from the upper molding die and the first lower molding die together with the core pin separation after the one-step molding, There is a problem in that the structure is complicated and the molding process is complicated, resulting in a low productivity and a high cost of production.

In addition, in Japanese Patent Registration No. 10-1447780, contents having fluidity at a high temperature (55 ° C to 95 ° C) are caused to flow in a transverse direction in a horizontally disposed filling mold, Shaped multicolor stick type cosmetics which are partitioned in a straight or oblique shape on the stick portion by the inclination angle change of the above-mentioned filling mold.

This technique is advantageous in that the manufacturing cost is reduced by a simple structure in which a secondary partition such as an interchangeable molding fixture or partition (hereinafter referred to as a molding frame) is not required in a filling mold for molding a multicolored stick type cosmetic product, There is a disadvantage that a cycle time is required to be long due to the injection molding of the contents, and it is difficult to repeatedly produce the same shape, so that there is a problem in that productivity and merchandising are inevitably lowered .

In addition, the conventional multi-colored stick type cosmetics manufactured as described above have a problem in that assembling workability is poor because the stick is molded and manufactured, and then the process of inserting and bonding the stick into the cosmetic container is manually performed.

Japanese Patent Application No. 10-0316447 discloses a technique for blowing compressed air from the opposite side of the cavity after stick forming in a molding die to push the stick cosmetic product and attaching the same to a cosmetic container placed at the outlet of the molding die, There is a problem that the extraction of stick cosmetics is not smooth due to the air, and the molding die is complicated due to a complicated structure for supplying compressed air.
