Description

[0001] CURVED GLASS FORMING APPARATUS [0002]

Various embodiments of the present invention relate to a curved glass forming apparatus, for example, a curved glass forming apparatus that allows the same heat to be transferred to a glass-loaded mold.

Generally, in an electronic device such as a smart phone or a tablet, a display portion for displaying information may be located on at least one of the one side or the other side of the electronic device.

Such an electronic device has been generally manufactured in an angular shape. However, recent electronic devices are provided so that corner portions can be formed as curved surfaces to realize design, aesthetics, and high quality.

In addition, the electronic apparatus is provided with a glass for protecting the display unit or the case located on one side or the other side of the electronic apparatus, wherein at least one of the glass mounted on the front surface or the rear surface of the electronic apparatus, Should be provided so as to have a curved shape corresponding to the shape of the electronic device.

A generally used method of forming a curved surface of a glass is to polish the glass surface with a glue or the like to form a curved surface. However, the method of grinding the glass to form the curved glass has a limitation in the shape that can be molded, and may cause waste of the glass material. Therefore, a bending method in which a glass is heated to a working temperature by using a heating method and then bent is used instead of a method of forming a curved glass by polishing the glass. Such a bending method requires a glass forming apparatus suitable for mass production of curved glass.

Fig. 1 is a view showing a general curved glass forming apparatus 50. Fig.

1, the curved-surface glass forming apparatus 50 includes a mold 53 for molding a flat glass into a curved glass by heat transmitted by at least one of the glasses placed thereon, And a heating member for applying heat.

The mold 53 may include a lower mold and an upper mold, and a cavity in which the glass is seated can be formed.

Further, the mold 53 may be formed with a plurality of cavities adjacent to each other so that at least one of the at least one flat plate-shaped glass can be formed into a curved glass.

Alternatively, the upper mold and the lower mold may be combined to form a monolayer mold 53. Alternatively, at least one intermediate mold 53 may be formed between the upper mold and the lower mold, A multi-layered metal mold 53 may be provided.

The heating member is provided on the mold 53 so as to support the mold 53 and press it while transferring heat to the mold 53 to mold the flat plate glass into a curved glass .

The heating member may include a lower heating member (52) and an upper heating member (51).

The lower heating member 52 may be provided to transmit heat from the lower side of the mold 53 to the mold 53 while the mold 53 is seated.

The upper heating member 51 is disposed on the upper portion of the lower heating member 52 and rests on the upper portion of the metal mold 53 seated on the lower heating member 52 to press the upper portion of the metal mold 53, To transfer the heat from the upper part to the mold 53.

When the heat is transferred from the upper heating member 51 and the lower heating member 52 to the mold 53 by placing the lower heating member 52, the mold 53 and the upper heating member 51 in this order, 53 apply heat to the glass side mounted in the seating space to form a flat glass into a curved glass.

However, in the curved glass molding apparatus having the above structure, as the heating member applies heat to the upper and lower sides of the mold around the metal mold, heat may not be transmitted to the side surfaces.

Therefore, the same heat can not be transmitted as a whole to the mold, and heat transmitted to the glass placed inside the mold can not be uniformly transmitted.

Further, since a certain heat is not transferred to the glass, defects may occur in the shape of the curved glass or an accurate curved shape may not be formed.

The curved glass forming apparatus according to various embodiments of the present invention can uniformly distribute the heat transmitted to the mold on which the glass is placed and can achieve the same molding quality even if a plurality of curved glass is formed, So as to provide a curved glass molding apparatus capable of improving the curvature of the curved glass.

A curved glass forming apparatus according to various embodiments of the present invention includes:

A lower heating member disposed at a lower portion of a mold portion having at least one cavity for forming a curved glass and providing heat to the mold portion;

An upper heating member disposed on the upper side of the mold part and providing heat to the mold part; And

And a side heating member disposed on the side of the mold section and covering at least a part between the upper heating member and the lower heating member and providing heat to the mold section.

Further, the curved glass forming method according to various embodiments of the present invention includes:

Placing a glass with a cavity provided in a mold part;

Placing the mold with the glass mounted thereon on the lower heating member;

Placing an upper heating member on the lower heating member;

Moving the lower heating member and the upper heating member in directions adjacent to each other;

The side heating member provided on at least one of the lower heating member and the upper heating member on the opposite side of the lower heating member and the upper heating member covers the periphery of the mold portion; And

And transferring heat from the upper heating member, the lower heating member, and the side heating member to the metal mold to mold the curved glass.

The curved surface forming apparatus according to various embodiments of the present invention can transmit heat through not only the upper portion and the lower portion but also the side portion of the metal mold and can transmit heat uniformly to the entire surface of the metal mold,

As the heat is uniformly transmitted through all the surfaces of the mold, the heat transferred to the glass disposed inside the mold is constant, so that a curved glass having the same molding quality can be produced at the time of molding the curved glass, Can be increased,

The heat transfer to the entire mold can be made constant, and the productivity of the curved glass having the same quality can be improved. For example, even when forming a curved glass with a multi-layer mold as well as a single-layer mold, heat of the same temperature as the upper and lower surfaces is transferred to the mold side as well as the upper and lower sides of the mold, Therefore, even when a plurality of curved glass is molded at a time, a curved glass of the same quality can be obtained, and productivity can be increased.
