Description

Mold apparatus with leather patterns {Mold apparatus with leather patterns}

The present invention relates to a mold apparatus having a leather pattern, and in more detail, a plurality of parts which are protruded by milling from a lower mold among the mold apparatuses to enable the leather to be integrally manufactured on the surface of the resin through insert injection. Forming a space, and forming at least one of the plurality of spaces by corroding to form a dark area, thereby forming a pattern for forming an animal's leather pattern directly on the lower mold. The present invention relates to a mold apparatus in which a leather pattern is formed to produce a plastic resin material in which the leather pattern is formed on the leather.

Accessories and designs of various shapes have been formed so that small electronic products and accessories can be purchased according to consumer preferences. In particular, the appearance of a product made of plastic resin is forming a shape of the product through injection molding, and various products have been released.

However, there is a limit in forming a pattern directly on the appearance of the plastic product through the injection process. Therefore, most plastic injection molding products are mainly injection molded and finished by attaching or coating films or other exterior materials to the outside.

In particular, in the case of designs requiring expression of different heights, colors, and shades in the plane, such as animal skins, for example, crocodile or snakeskin, the film was applied to a film and adhered to the outer surface of the plastic product.

Therefore, in the related art, since the coating work through a separate cover or film is additionally performed on the appearance of the plastic resin product, there is a problem in that the manufacturing cost of the product is increased.

The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to form a plurality of spaces protruding from the lower mold and partitioned, and to at least one of the plurality of spaces by corrosion treatment dark The present invention provides a mold apparatus in which a leather pattern is formed to form an area displaying an area to directly form a pattern capable of representing an animal's leather pattern on a lower mold.

In another aspect, the present invention is a mold device that is formed on the surface of the leather is inserted into the mold together with the plastic resin when the product such as the housing of the portable terminal through the injection molding is formed of a leather pattern pattern for molding the leather pattern of the animal at the same time It is about.

Mold device formed with a leather pattern pattern according to the present invention devised to achieve the above object, the lower mold to form the leather pattern of the animal on the outer surface of the plastic injection molded insert by the upper mold and the lower mold A leather pattern is formed on the leather pattern, and the leather pattern is corroded to at least one of the space part partitioning the surface into a plurality of the lower mold, and the space partitioned inside the lower mold. It is possible to realize that the surface includes an oblique portion that forms a plurality of protruding grooves to extend and visually produce a dark space in contrast to the space portion.

In addition, it is feasible to form a leather pattern on the surface of the leather in the insert injection where the leather is integrally injected onto the surface of the plastic injection molding.

According to the present invention, a pattern of an animal's leather pattern is formed in the lower mold and the plastic resin is injected to form an insert injection molded product, and at the same time, a pattern of a specific shape can be formed on the surface of the leather inserted with the plastic resin. It has an effect.

Therefore, conventionally, after forming a pattern on the surface of the leather separately, the process of attaching the leather with the pattern formed on the outside of the plastic injection molded product can be omitted, thereby reducing the manufacturing cost.

1 is a perspective view illustrating a mold apparatus in which a leather pattern is formed according to the present invention;
2 is a perspective view illustrating a product injected through a mold apparatus in which a leather pattern is formed according to the present invention.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a mold apparatus having a leather pattern according to the present invention will be described in detail.

1 is a perspective view showing a mold apparatus formed with a leather pattern pattern according to the present invention, Figure 2 is a perspective view showing a product injected through a mold apparatus formed with a leather pattern pattern according to the present invention.

1 and 2, the mold apparatus having a leather pattern according to the present invention is composed of an upper mold 32 and a lower mold 31 into which plastic resin in a heated liquid state is introduced.

The lower mold 31 has a leather pattern 33 is formed on the inner surface. The leather pattern pattern 33 is formed by partitioning a plurality of space portions 331 protruding from each other, and at least one or more spaces in the partitioned space include an oblique portion 332 having a diagonal surface.

Therefore, the space portion 331 and the diagonal portion 332 partitioned as described above represent, for example, a leather pattern of a reptile such as a crocodile. This is as shown in FIG. The pattern 33 of the leather pattern according to the present invention is produced by engraving the inner surface of the lower mold 31, the space portion 331 to protrude upward inside the lower mold 31 through a milling device. It is possible to form

At this time, the space 331 is protruded and formed between the space 331 is recessed so that the space between the space 331 is partitioned.

In addition, in the inner surface of the lower mold 31 formed as described above, one or more of the plurality of spaces 331 is selected and subjected to corrosion treatment. An oblique portion 332 is formed to surface-treat the surface of the space 331 so as to give an uneven feel.

More preferably, a groove is formed on the surface of the oblique portion 332 that is corroded by using a sharp tip tool to form a plurality of diagonal lines. Therefore, the pattern 33 may be formed in each space having different shades.

When the leather is inserted into the upper portion of the lower mold 31 formed as described above, the upper mold 32 is brought into close contact and the liquid plastic resin is injected at high temperature and high pressure. As shown in FIG. Is formed. At this time, the leather is processed in a state where the leather pattern is formed on the surface by the space portion 331 and the oblique portion 332 of the lower mold (31).

At this time, the leather which is the surface of the injection molded product 1 is a dark area 12 contrasted with the bright area 11 by the bright area 11 formed by the space part 331 and the oblique part 332. As it is injected to be divided into), it is processed with the feeling of natural crocodile leather.

Preferably, the leather pattern 33 as described above can obtain a greater aesthetic effect in injecting a housing for protecting and decorating the back of the portable electronic device. This is because the user can feel the leather pattern partitioned by the space portion 331 and the oblique portion 332 as the tactile tactile sense of the portable terminal such as a mobile phone, a smartphone, a PDA, a netbook, and a tablet PC. It is good to apply to the case.

This means that when the case of the portable terminal has a leather pattern design by the leather pattern pattern 33 as described above, the friction between the portable terminal and the palm of the user can be increased by the leather pattern clearly distinguished through the touch. This is because the adhesion between the hand and the portable terminal is increased.

In addition, the present invention can be used permanently as compared to the method of forming each design on the surface of the existing film, the film is bonded to the portable terminal, the cost of purchasing and designing the film at the time of production, and the adhesion of the film The manufacturing cost can be saved because it is cheaper in the process and the resultant manufacturing labor and less work labor.

While the present invention has been described in detail with respect to the specific examples described, it will be apparent to those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention, and such modifications and modifications belong to the appended claims.
