Abstract

The present invention relates to a core molding apparatus of a cosmetic pencil, which is capable of further improving quality by respectively supplying a raw material of the core at a front surface of core molding units and inserting the molded core into a pencil casing by means of an insertion pin. The apparatus comprises: a fixed block (30) in which a plurality of core molding apparatuses (100) are radially provided on a rotary table (10) of an apparatus for producing a cosmetic pencil, and of which the upper side is fixed to the rotary table (10) and the lower side is vertically coupled to a pair of guides (50); a plurality of core molding units (40) which penetrate through the upper side and the lower side of the fixed block (30) and are vertically coupled thereto, and in which a molding hole (41) penetrating through the upper side and the lower side thereof is formed, and at the lower side thereof a raw material injection hole (42) communicating with the molding hole (41) is formed; and a moving block (60) which is coupled to the guide (50) so as to be vertically movable and to which a plurality of insertion pins (70) inserted in the molding hole (41) are vertically coupled. Accordingly, the present invention supplies the raw material of the core with the same pressure at the front surface of the plurality of core molding units, and inserts the molded cores into each of the pencil casings by respective insertion pins, so that cores with uniform lengths and density can be formed at all times, and the defect rate can be reduced, thereby being capable of remarkably improving the quality of a cosmetic pencil. In addition, since the raw material of the core is injected from the side, there is an effect that a cosmetic pencil having a small diameter can be easily manufactured.

Description

Body forming device of side injection type cosmetic pencil

The present invention relates to a device for molding the core of the pencil used in the makeup of the lips or eyelashes, and more particularly, the raw material of the core is supplied from the front of the core molded part, respectively, and the molded core is inserted into the pencil case by the insertion pin. The present invention relates to a body injection molding apparatus for a side injection type cosmetic pencil which can further improve quality.

Lip liners and eyeliners are generally cosmetic products used by women for lip or eye makeup. These cosmetics are provided in the inner pencil case the core that plays the most important role in the contour makeup of the lips or eyelashes.

Since the role of the body is based on the contour of the lips, eyebrows or eyelashes, it must be thinly formed so that delicate and detailed makeup can be performed. Therefore, it is possible to maximize the life and productability only when the diameter of the core is reduced and there is no loss of use.

Patent No. 10-0416788 in the molding process to minimize the occurrence of bubbles in the contents of the core body is compact, there is no damage to the appearance can be used without breaking, the core is molded to the smallest diameter as possible to maximize the productability A core molding method and a molding mold thereof are provided.

However, the above-mentioned core molding mold has a problem in that the contents are passed through the contents guide passage and the contents connecting passage in turn and are filled in the core molding holes at different distances, so that the same pressure does not work and the lengths of the cores are different.

In addition, the upper molding mold and the lower base mold has to be manufactured separately, and there is a problem in that it takes a lot of cost and time to mold because the operation of combining or separating the lower base mold to the upper mold is repeated.

In addition, since the compressed air is used when the core is inserted into the inside of the pencil case, there is a problem in that a poor coupling occurs frequently depending on the pressure change.

In particular, since the conventional core molding apparatus is a method of inserting the nozzle of the core from the upper side, it is impossible to manufacture a cosmetic pencil having a diameter of less than a predetermined.

The present invention is to solve the above problems, to provide a core molding apparatus of the side injection method cosmetic pencil that can always mold a core of a certain length and density by improving the core material supply method. have.

Another object of the present invention is to provide a core injection molding apparatus for a side injection type cosmetic pencil which can reduce a defective rate by improving a method of inserting a molded core into a pencil case.

In the core injection molding apparatus for side injection cosmetic pencil according to the present invention, a plurality of core molding apparatuses are radially installed on a rotating table of a device for manufacturing a cosmetic pencil, and the upper side is fixed to the rotating table, and a pair is provided on the lower side. A fixed block to which the guides are vertically coupled; A plurality of core molding parts which are vertically coupled to penetrate the upper side and the lower side of the fixed block, and have a forming hole penetrating the upper side and the lower side thereof, and having a raw material injection hole communicating with the forming hole at the lower side thereof; It is coupled to the guide so as to move up and down, a plurality of insertion pins inserted into the molding hole is a vertically coupled moving block; characterized in that it comprises a technical feature.

According to the core molding apparatus of the side injection cosmetic pencil according to the present invention, the core material is supplied at the same pressure from the front of the plurality of core molding parts, and the molded core is inserted into the pencil case by the respective insertion pins. The core can be molded to a certain length and density, and the defect rate can be reduced, thereby significantly improving the quality of the cosmetic pencil. In addition, since the method of injecting the raw material of the core from the side, there is an effect that can easily manufacture a small cosmetic pencil.
