SUMMARY OF THE INVENTION

However, when an auxiliary raw material disposed on a raw material is integrally molded with the raw material using the conventional forming mold, the following problems occur as described with reference to FIGS. 4A and 4B.

(1) An auxiliary raw material (31) is disposed on a raw material (30) disposed on a lower mold 10, and then an upper mold (20) is shape-coupled to the lower mold (10) to form a molded product. In this case, since an area of the auxiliary raw material (31) is relatively smaller than an area of the raw material, the auxiliary raw material (31) should be disposed at a predetermined position.

(2) That is, the auxiliary raw material (31) is disposed to partially overlap the area of the raw material (30) so that the auxiliary raw material (31) partially covers a surface of a molded product or is integrally formed with the molded product to achieve predetermined objectives of partially reinforcing rigidity, blocking heat transfer, and the like.

(3) In this case, when the auxiliary raw material (31) is not disposed at the predetermined position on the raw material (30) disposed on the lower mold (10), not only a desired function may not be obtained, but a molding defect may also occur.

(4) In addition, since an operation of arranging the auxiliary raw material (31) on the raw material 30 is performed manually, not only it is difficult to arrange the auxiliary raw material (31) at the predetermined position, but it also takes a long time to accurately arrange the auxiliary raw material (31) at the predetermined position. Accordingly, a time for forming the molded product increases, and as a result, productivity is lowered.

(5) In addition, there is a risk of accidents occurring when a position is adjusted to arrange the auxiliary raw material (31) at the predetermined position.

The present invention is directed to providing a forming mold in which a laser pointer is mounted on an upper mold and formed to mark a position of an auxiliary raw material disposed on a raw material disposed on a lower mold so that everyone easily accurately arranges the auxiliary raw material at a predetermined position and molds the auxiliary raw material to improve a molding efficiency.

In particular, the present invention is also directed to providing the forming mold in which the laser pointer is formed to mark vertex positions of the auxiliary raw material so that an operator arranges vertexes of the auxiliary raw material at the predetermined positions to quickly arrange the auxiliary raw material at the predetermined position and accurately mold the auxiliary raw material.

In this case, the present invention is also directed to providing the forming mold in which at least two laser points are mounted along an edge of the upper mold to mark vertices of the auxiliary raw material so that the auxiliary raw material is more quickly accurately disposed at the predetermined position and integrally molded.

According to an aspect of the present invention, there is provided a forming mold including a lower mold (100) on which a raw material (110) to be molded in a predetermined shape is disposed and an upper mold (200) installed to face the lower mold (100) and shape-coupled to and shape-separated from the lower mold (100), wherein at least one laser pointer (210) is mounted on the upper mold (200), and the laser pointer (210) marks a position of an auxiliary raw material (111) when the auxiliary raw material (111) is disposed on and integrally molded with the raw material (110).

The laser pointer (210) may be mounted to mark at least two vertices of the auxiliary raw material (111).

In addition, the laser pointer (210) may be provided as at least two laser pointers (210) installed along an edge of the upper mold (200) and mark vertices of the auxiliary raw material (111).

[Structure of Forming Mold]

As illustrated in FIGS. 5A, 5B, 6, and 7, a forming mold according to the present invention includes a lower mold 100 on which a raw material 110 is disposed and an upper mold 200 which faces the lower mold 100 to be shape-coupled to and shape-separated from the lower mold 100.

In particular, as at least one laser pointer 210 is mounted on the upper mold 200, when an auxiliary raw material 111 is disposed on and integrally molded with the raw material 110 disposed on the lower mold 100, a position at which the auxiliary raw material 111 is disposed on the raw material 110 is marked, and the auxiliary raw material 111 is quickly accurately disposed at a predetermined position on the raw material 110 and integrally molded with the raw material 110.

In this case, as the laser pointer 210 is formed to indicate a position at which a vertex portion of the auxiliary raw material 111 is disposed, a vertex of the auxiliary raw material 111 is determined and easily accurately disposed at a point indicated by the laser pointer 210 so that the auxiliary raw material 111 is accurately molded and a defect rate is reduced.

In addition, as at least two laser pointers 210 are installed on a perimeter of an edge of the upper mold 200 to indicate vertex portions of the auxiliary raw material 111, the auxiliary raw material 111 is accurately positioned at a predetermined position.

Hereinafter, such a structure will be described in more detail with reference to the accompanying drawings.

A. Lower Mold

As illustrated in FIGS. 5A and 5B, the raw material 110 required for molding a molded product is disposed on the lower mold 100, and the lower mold 100 supports the raw material 110. As the upper mold 200, which will be described below, is shape-coupled to the lower mold 100, the raw material 110 is molded in a predetermined shape to produce the molded product.

Accordingly, as illustrated in FIG. 5FIGS. 5A and 5B, a cavity in a spatial type is formed in a surface of the lower mold 100 facing the upper mold 200 to form a shape of the molded product. In addition, although the raw material 110 is formed into a complex three-dimensional shape after being molded, the raw material 110 which has a flat shape or is flexible like fabric is mainly used when the raw material 110 is disposed on the lower mold 100.

In addition, as illustrated in FIGS. 5A, 5B, 6, and 7, the auxiliary raw material 111 is disposed on the surface, which faces the upper mold 200, of the raw material 110 disposed on the upper mold 200. In this case, the auxiliary raw material 111 refers to a member disposed to partially overlap the surface of the raw material 110 and integrally molded to obtain secondary effects of reinforcing rigidity, improving noise performance, and the like.

As illustrated in FIG. 5, the lower mold 100 formed as described above is installed to face the upper mold 200.

B. Upper Mold

As illustrated in FIGS. 5A, 5B, and 6, the upper mold 200 is installed to face the lower mold 100 described above. In addition, on a surface of the upper mold 200 facing the lower mold 100, a cavity is formed in a shape of the molded product formed of the raw material 110.

In addition, as illustrated in FIGS. 5A, 5B, and 6, at least one laser pointer 210 is mounted on the upper mold 200. In this case, the laser pointer 210 is mounted at a position at which the laser pointer 210 is not interfered with when the lower mold 100 and the upper mold 200 are shape-coupled, and when the upper mold 200 is shape-separated from the lower mold 100, the laser pointer 210 may emit a laser beam onto a surface of the raw material 110 to indicate a stacking position of the auxiliary raw material 111 disposed on the raw material 110.

In the exemplary embodiment of the present invention, as illustrated in FIG. 6, as the laser pointers 210 are mounted on the upper mold 200 to emit laser beams at vertex positions of the auxiliary raw material 111 when emitting the laser beams onto the surface of the raw material 110, when the auxiliary raw material 111 is disposed on the raw material 110, at least two vertices of the auxiliary raw material 111 may be disposed at points indicated by the laser pointers 210 to quickly arrange the auxiliary raw material 111 at a predetermined position on the surface of the raw material 110 so that the auxiliary raw material 111 is molded.

In addition, in an exemplary embodiment of the present invention, as illustrated in FIG. 7, as at least two laser pointers 210 are mounted on an edge portion of an upper mold 200, and the laser pointers 210 are formed to mark vertex positions of an auxiliary raw material 111, the auxiliary raw material 111 can be more accurately quickly disposed at a predetermined position on a surface of the raw material 110 so that the auxiliary raw material 111 is molded.

As described above, in the present invention, as the laser pointer is mounted on the upper mold and installed to indicate a position at which a vertex of the auxiliary raw material is disposed, the auxiliary raw material can be easily quickly accurately disposed and molded at a predetermined position on the surface of the raw material. In this case, as at least two laser pointers are installed to indicate vertex positions of the auxiliary raw material, the auxiliary raw material can be more easily accurately disposed at a desired position so that a molding process may be performed.

A forming mold according to the present invention has the following effects.

(1) As a position of an auxiliary raw material disposed on a raw material is accurately pointed using a laser pointer, everyone can easily accurately arrange the auxiliary raw material at a predetermined position on the raw material.

(2) Accordingly, when the raw material and the auxiliary raw material are integrally molded, the auxiliary raw material can be quickly disposed at the predetermined position, and thus a raw material molding efficiency can be improved.

(3) In addition, since the auxiliary raw material is accurately disposed at the predetermined position as described above, the auxiliary raw material can be prevented from deviating from the predetermined position to reduce a defect rate and improve productivity.

(4) Meanwhile, as the laser pointer is formed to mark a position according to a position at which vertexes of the auxiliary raw material are positioned on the raw material, everyone can use the vertexes of the auxiliary raw material to accurately arrange the auxiliary material at the predetermined position.

(5) In this case, as at least two laser pointers are installed on a perimeter of an upper mold and mounted at positions at which the laser points can mark vertices of the auxiliary raw material, the auxiliary raw material can be more accurately quickly disposed at the predetermined position and integrally molded.
