Tempered glass used as a cover of a mobile electronic device is generally manufactured by inserting an object into a mold, heating it with high heat, and then cooling it. Conventional glass forming apparatuses are each provided with a preheating, heating and cooling step in a plurality of chambers. Therefore, after each process is completed, the mold has to be transferred each time to carry out the next process, so that it is difficult to reduce the tact time and the productivity is lowered.

Further, in the conventional glass molding apparatus, a process of heating and molding a mold on which a glass is mounted is performed by a conventional electric heater that generates heat by electric resistance. Such an electric heater consumes a large amount of electric power, There was a problem that was difficult to lower.

In addition, the conventional glass forming apparatus can not transmit heat evenly to the mold on which the glass is mounted, so that there is a problem that the quality of the formed glass is uneven.

Further, the apparatus for pressing the mold in the conventional glass forming apparatus to give the pressing force to the glass mounted on the mold is more complicated than necessary, and the investment cost is increased, and it is difficult to uniformly apply the pressing force to each portion of the mold, There is a problem in that it is lowered.

In addition, among the various processes, a relatively long time is required in the process of cooling the heated mold, so that it is difficult to reduce the overall molding time, thereby increasing the molding cost.

In addition, there has been a problem that the glass is oxidized by contact with oxygen during the molding process. To improve this, the nitrogen is not effectively prevented from flowing out of the molding apparatus when injecting nitrogen, There has been a problem that the molding cost is increased.

The heating unit 1200 can heat the mold M in which the glass is housed. The heating unit 1200 may be one or more.

1 to 5, a heating unit 1200 according to an embodiment of the present invention includes a chamber 1210, a heating module 1220, a pressing module 1230, and a seating module 1240.

A heating space is formed inside the chamber 1210, and an entrance through which the mold M can enter and exit can be formed. A heating module 1220 to be described later may be located inside the chamber 1210. The chamber 1210 may be, for example, a hexahedron, but is not limited thereto.

The door module 1260 is coupled to the chamber 1210. The door module 1260 may be installed in the chamber 1210 at a portion where the door is formed to open or close the door.

The door module 1260 may include an opening and closing door 1261 and a door driving part 1262 for operating the opening and closing door 1261. For example, when the opening / closing door 1261 is moved upward by the door driving unit 1262, the door is closed. When the door 1261 is moved downward by the door driving unit 1262, the door can be opened. Here, a seal member may be interposed between the opening / closing door 1261 and the chamber 1210. The seal member (not shown) can prevent the nitrogen supplied to the chamber 1210 from being lost to the outside.

Although one door module 1260 is illustrated as being installed in the chamber 1210, a plurality of door modules 1260 may be installed in the chamber.

The heating module 1220 can heat the mold M containing the glass to mold the glass. The heating module 1220 is disposed inside the chamber 1210.

Referring to FIG. 5, a space is formed in the interior of the mold M to accommodate unformed glass having a flat plate shape, and the space may have a shape corresponding to the shape of the desired glass. The mold M is configured to be separated into an upper portion and a lower portion, for example, so that the injection of unformed glass into the mold M and the molded glass from the mold M can be easily separated.

The heating module 1220 may include a conventional electric heater or a high-frequency type heater. That is, the heating module 1220 may be a conventional electric heater or a high-frequency type heater, but a high-frequency heater is preferably used. However, the heating module 1220 is not limited to a high-frequency type heater, and an ordinary electric heater may be applied.

 The high-frequency type heater has a relatively low power consumption as compared with a conventional electric heater. For example, a high-frequency heater can generate the same heat while consuming about 50% less power than a conventional electric heater.

As described above, the heating module 1220 included in the heating unit 1200 according to the embodiment of the present invention lowers the power consumption by heating the glass with the high-frequency type heater, as compared with the case where the glass is heated only by the ordinary electric heater It is possible to reduce the cost of molding the glass.

The heating module 1220 may include a space member 1221 and a heating member 1222, for example.

The space member 1221 may be formed to surround the heating space. For example, the shape of the vertical section of the space member 1221 may be tubular. The space member 1221 may be made of ceramic. Alternatively, the space member 1221 may be made of refractory cement.

The heating member 1222 may be inserted into the space surrounding the heating space of the space member 1221 so as not to be exposed to the outside, so that a high-frequency current may flow. When a high frequency current is applied to the heat generating member 1222, heat is generated by the induction current, and such heat can be transferred to the mold M. The heating member 1222 may be, for example, a coil or a copper tube. The heating member 1222 may be inserted into the space member 1221 in a spring shape. A power supply unit 1223 is connected to the heating member 1222. The power supply unit 1223 supplies a high frequency current to the heating member 1222 to generate heat for heating the mold M. [

The space member 1221 described above can prevent the mold M from directly contacting the heating member 1222 as well as allowing the heat generated from the heating member 1222 to be uniformly transmitted to the mold M have. That is, when the glass is molded by the heating unit 1200 according to the present invention, the mold M is uniformly heated in the heating space of the heating module 1220 to stably form the glass structure, Can be even better. To this end, the mold M may be located at the center of the heating space, and the position of the mold M may be adjusted by operation of the seating module 1240.

The seating module 1240 may be configured to be accessible to a portion of the heating module 1220. That is, the seating module 1240 can change the position of the mold M while supporting the mold M in a state where the mold M is positioned in the heating space. The seating module 1240 supports the mold M so that the mold M can be positioned in the center in the vertical direction of the heating space.

As a result, the generated heat is uniformly transmitted to the mold M, whereby it is possible to prevent only a specific portion of the mold M from being heated. Therefore, the glass inside the mold M can be uniformly heated.

To this end, at least one access hole H penetrating in the vertical direction may be formed on the lower side of the space member 1221. The seating module 1240 may include at least one seating member 1242 and a seating driving unit 1243 for moving the seating member 1242.

The seating member 1242 may be formed to have a length and be vertically positioned in the chamber 1210. The seat member 1242 can be moved up and down by the seat driving unit 1243 through the access hole H.

The upper side on which the mold M is seated in the seating member 1242 can be located in the heating space. The mold M introduced into the chamber 1210 may be seated on the seating member 1242. As the seat member 1242 is moved in the vertical direction, the height of the seated mold can be varied.

For example, when the mold M introduced into the chamber 1210 is relatively thick, the seating member 1242 may be lowered and the mold M may be positioned in the center in the vertical direction of the heating space . Alternatively, when the mold M introduced into the chamber 1210 is relatively thin, the seating member 1242 rises and the mold M can be positioned in the center in the vertical direction of the heating space.

At least one of the seating members 1242 is provided. When the plurality of the seating members 1242 are provided, the seating member 1242 may be connected to the seating plate 1241 and the seating plate 1241 may be connected to the seating driving unit 1243. Accordingly, the plurality of seating members 1242 can be raised or lowered simultaneously.

Alternatively, the seating plate 1241 may be omitted, and in this case, the seating member 1242 may be directly connected to the seat driving unit 1243.

In addition, the heating unit 1200 according to an embodiment of the present invention may include a pressing module 1230. The pressing module 1230 presses the mold M by an external force so that the glass positioned in the mold M can be uniformly molded.

The pressing module 1230 may include a pressing member 1232 and a pressing driving unit 1233 for operating the pressing member 1232. [

The pressing member 1232 may be provided on the upper surface of the space member 1221 and may include at least one through hole H penetrating the pressing member 1232 in the up and down direction. The mold M can be pressed while being moved by the operation of FIG.

The pressing member 1232 may be formed to have a length and be vertically positioned in the chamber 1210.

At least one of the pressing members 1232 is provided. The pressing member 1232 may be connected to the pressing plate 1231 and the pressing plate 1231 may be connected to the pressing driving unit 1233. In the case where the pressing member 1232 is provided in plurality, Accordingly, the plurality of pressing members 1232 can be simultaneously raised or lowered to press the mold M.

Alternatively, the pressure plate 1231 may be omitted, and in this case, the pressure member 131 may be directly connected to the pressure driver 1233.

The pressing drive unit 1233 and the seat driving unit 1243 may be exemplified by a motor, a cylinder, and the like, but the present invention is not limited thereto. The pressing drive unit 1233 and the seat driving unit 1243 may be any of those capable of moving the pressing member 1232 and the seating member 1242 It is possible to do it.

The pressing member 1232 and the seating member 1242 may have the same structure. The pressing member 1232 and the seating member 1242 may be plural. For example, the pressing member 1232 and the seating member 1242 may be six, such as the cap shown in Fig. The six pressing members 1232 can uniformly press the upper side of the mold M as a whole while the six seating members 1242 stably support the mold M. [

The pressure driver 1233 and the seating driver 1243 may be located outside the chamber 1210 as shown, but may be located within the chamber 1210. [ That is, although the pressing member 1232 and the seating member 1242 are illustrated as moving through the chamber 1210 in the drawing, the pressing member 1232 and the seating member 1242 are shown as being moved in the chamber 1210 , And the pressure driver 1233 and the seating driver 1243 may be installed inside or outside the chamber.

Further, the heating unit 1200 according to an embodiment of the present invention may include a nitrogen supply unit (not shown).

The nitrogen supply unit may be connected to the chamber 1210 to supply nitrogen into the chamber 1210. Accordingly, in the process of heating the mold M inside the chamber 1210, the inside of the chamber 1210 becomes nitrogen atmosphere, and the heating of the mold M can be stably performed. At this time, it is preferable that nitrogen is directly supplied to the heating space formed by the space member 1221.

In addition, the heating unit 1200 according to an embodiment of the present invention may further include a guide unit (not shown) for guiding the movement of the pressing module 1230 and the seating module 1240. The detailed structure of the guide portion for guiding the movement of the pressing module 1230 and the seating module 1240 is well known in the art, and thus a detailed description thereof will be omitted.

Further, the heating unit 1200 according to an embodiment of the present invention may further include a temperature sensor (not shown) for directly measuring the temperature of the mold M. An entrance hole (not shown) similar to the above-described access hole H is formed in the space member 1221 for installing a temperature sensor (not shown), and the temperature sensor is connected to the mold M through the access hole Can be installed adjacent to each other. When the temperature sensor is used, the temperature of the mold M to be heated can be directly measured.

6 is a view showing a heating unit according to another embodiment of the present invention.

The heating unit according to another embodiment of the present invention has substantially the same structure as the heating unit according to the previous embodiment, but further includes a pressure adjusting module 1250.

The pressure regulating module 1250 may include a cylinder 1251 and a regulator 1252 connected to the cylinder.

An auxiliary plate 1253 may be connected to the pressing member 1232 and the cylinder 1251 may be connected to the auxiliary plate 1253 and the pressing plate 1231. Also, the cylinder 1251 may be connected to the regulator 1252.

The pressure adjusting module 1250 adjusts the deviation of the pressing force caused by machining variations of the mechanical parts and the like. The pressing force is adjusted by the cylinder 1251 and the regulator 1252 connected to the cylinder 1251.

More specifically, when the pressing member 1232 presses the mold M, an appropriate pressing force is set. When a plurality of pressing members 1232 are formed, the pressing force may be set differently for each pressing member 1232, and all the pressing members 1232 may be set to be the same.

When the pressing member 1232 presses the mold M by the action of the pressure driver 1233, the pressing member 1232 is pressed against the mold M by the machining deviation of the constituent elements (mechanical parts such as the guide part) The pressing force for pressing the mold M may be different from the pressing force for setting the pressing force.

The pressure adjusting module 1250 is for adjusting the pressing force when the pressing force is different from the pressing force as described above and the cylinder 1251 and the regulator 1252 connected to the cylinder 1251 are operated to set the pressing force .

7 is a view for explaining a heating unit according to another embodiment of the present invention. The heating unit according to the present embodiment has substantially the same configuration as that of the heating unit according to the foregoing embodiment, and only the pressure adjusting module is changed.

That is, in this embodiment, the pressing force is adjusted by the spring 1254 and the adjusting bolt 1255 instead of the cylinder 1251 and the regulator 1252 connected to the cylinder 1251.

More specifically, an auxiliary plate 1253 can be connected to the pressing member 1232, and the auxiliary plate 1253 can be connected to the spring 1254. The spring 1254 is provided with a spacer (not shown) connected to the adjusting bolt 1255 1256 may be connected.

The pressure adjusting module included in another embodiment of the present invention having the above-described configuration is configured such that when the pressing member 1232 is different from the pressing force for pressing the mold M, The pressing force is adjusted to the set pressing force by adjusting the elastic force of the pressing member 1254.

By adjusting the pressing force applied to the mold M by the pressure adjusting module as described above, glass having more stable quality can be molded.

The mold M is conveyed to the first cooling unit 1300 by the first conveyance unit 1400 when the heating unit 1200 completes the molding by heating. The first transfer unit 1400 will be described later.

The first cooling unit 1300 cools the mold M. [ More specifically, the first cooling unit 1300 slowly cools the mold at room temperature so that the quality of the formed glass can be stabilized. The first cooling unit 1300 may include at least one first cooling chamber 1310. The first cooling chamber 1310 may allow cooling of the mold M transferred from the heating unit 1200 by the first transfer unit 1400 in a state in which the mold M is hermetically sealed. The first cooling chamber 1310 may be installed on a first rotating plate, which will be described later, to cool the mold M while being rotated. That is, the first cooling chamber 1310 can continuously cool the mold during rotation and for a period of time waiting to receive another heated mold.

1, 8 and 9, the first cooling unit 1300 includes a first rotating plate 1330, a first rotating unit 1340, and a plurality of first cooling chambers 1310 .

The first rotating plate 1330 may have a circular shape. The first cooling chamber 1310 may be positioned at regular intervals along the edge of the upper surface of the first rotating plate 1330. For example, when the first cooling unit 1300 includes eight first cooling chambers 1310, the first cooling chamber 1310 is rotated at a 45 degree angle with respect to the central portion of the second rotating plate 1330, However, the number of the first cooling chambers 1310 is not limited to eight. However, considering that it takes much more time for the cooling process than the heating process in the normal glass forming process, it is preferable that the number of the first cooling chambers 1310 in the present invention is larger than the number of the heating units 1200 , Which is also true of the second cooling chamber to be described below.

The first rotating means 1340 may be coupled to the first rotating plate 1330 to rotate the first rotating plate 1330. More specifically, the first rotating unit 1340 may be coupled to the first rotating plate 1330 to rotate the first rotating plate 1330 clockwise or counterclockwise.

During the rotation of the first rotating plate 1330, the mold M can be received in the first cooling chamber 1310 and cooled. It is also possible that the cooling of the mold M proceeds in a state where the rotation of the first rotation plate 1330 is stopped for a predetermined time after the rotation of the first rotation plate 1330 by a predetermined angle.

The first cooling chamber 1310 is formed with an inner space for cooling the mold M and an opening and closing door 1320 may be installed on one side of the first cooling chamber 1310 so that the heated mold M can be taken in and out. An actuator for operating the opening / closing door is connected to the opening / closing door 1320.

The opening and closing door 1320 can prevent the nitrogen supplied into the first cooling chamber 1310 from being lost to the atmosphere, thereby reducing the nitrogen consumption amount. Therefore, the use of nitrogen for molding the glass can be minimized, so that the glass molding cost can be reduced.

Meanwhile, a nitrogen supply unit (not shown) may be connected to the first cooling chamber 1310. The nitrogen supply unit (not shown) supplies nitrogen to the inside of the first cooling chamber 1310 so that the inside of the first cooling chamber 1310 becomes a nitrogen atmosphere, so that the cooling process can be performed more stably. This nitrogen supply unit (not shown) may be installed in each of the first cooling chambers 1310 or only a part of the second cooling chamber 1310.

The mold M having been heated in the heating unit 1200 is transferred to the first cooling unit 1300 by the first transfer unit 1400 as described above.

In other words, the first transfer unit 1400 can transfer the mold M, which has been heated in the heating unit 1200, to the first cooling unit 1300 in a state in which the mold M is hermetically sealed from the outside. The first transfer unit 1400 may be one or more. The mold M can be moved in and out through one side of the first transfer unit 1400.

The first rotation unit 1420 is coupled to one side of the first transfer unit 1400 so that as the first transfer unit 1400 is rotated, a portion of the first transfer unit 1400, It is possible to rotate the first transfer unit 1400 so as to be positioned in close contact with the first cooling chamber 1310 of the unit 1200 and the first cooling chamber 1310 of the first cooling unit 1300. [

The first rotation unit 1420 may be a rotary motor coupled to the lower side of the first transfer unit 1400, for example. When the first rotation unit 1420 rotates the first transfer unit 1400, a portion of the first transfer unit 1400 in which the mold enters and exits can be rotated with respect to the first rotation unit 1420. Accordingly, the portion of the first transfer unit 1400 in which the mold enters and exits may be in close contact with the heating unit 1200 and may be in close contact with the first cooling chamber 1310 of the first cooling unit 1300.

10 and 11, the first transfer unit 1400 includes a gripping member 1411, an elevating member 1412, a sliding member 1414, a housing 1416, a contact member 1417, An opening / closing member 1418 and a driving module 1419.

The gripping member 1411 can grip the mold M. [ The gripping member 1411 may include, for example, a base portion 1411b and a support portion 1411a.

The base portion 1411b may be in the form of a plate having a circular or polygonal shape, for example. The support portion 1411a may be formed to have a length and may be coupled to the base portion 1411b. This support portion 1411a can support the lower side of the mold M that has been heated in the heating unit 1200 or the mold M that has been cooled in the first cooling unit 1300. [

The shape of the support portion 1411a for this purpose may be, for example, a shape in which two rod-shaped members are formed parallel to each other. The supporting portion 1411a may be formed such that a portion U facing each other in the two rod-like members is drawn in a predetermined depth. This can prevent the mold M from being detached from the support portion 1411a in a state of being placed on the drawn-in portion U of the support portion 1411a.

After the heating in the heating unit 1200 is completed, the support portion 1411a supports the lower side of the mold M so that the mold M can be lifted up to a certain height and transferred from the heating unit 1200 to another position.

The lifting member 1412 can be coupled to one side of the gripping member 1411. The elevating member 1412 can elevate the gripping member 1411 so that the mold M gripped by the gripping member 1411 can be moved up and down.

The elevation member 1412 can raise or lower the gripping member 1411 in a state where the mold M is positioned on the support portion 1411a of the gripping member 1411. [ The mold M may be in a movable state from the heating unit 1200 and the mold M may be placed in the first cooling unit 1300. [

The sliding member 1414 may be coupled to one side of the elevating member 1412. The sliding member 1414 can move the elevating member 1412 in a direction in which the sliding member 1414 moves away from or closer to the first rotating unit 1420.

The sliding member 1414 may be, for example, a rail or an LM guide and an actuator for imparting a moving force. However, the present invention is not limited thereto, and any sliding member 1414 may be used as long as it can move the gripping member 1411.

The elevating member 1412 is coupled to one side of the holding member 1411 and the sliding member 1414 is coupled to one side of the elevating member 1412. However, the present invention is not limited thereto. That is, the lifting member 1412 and the sliding member 1414 are for lifting and moving the gripping member 1411 in one direction, and the order and structure in which the gripping member 1411 is coupled to the gripping member 1411 can be variously changed, This is the same in the following embodiments.

The housing 1416 can receive the gripping member 1411, the elevating member 1412, and the sliding member 1414. [ The housing 1416 may be formed such that one side thereof is opened so that the gripping member 1411 can be taken in and out.

The contact member 1417 may be linearly reciprocated along the longitudinal direction of the housing 1416 while surrounding the end portion adjacent to the opening formed portion of the housing 1416. That is, the contact member 1417 can be linearly reciprocated along the longitudinal direction of the housing 1416. The entire length of the first transfer unit 1400 may be variable by such a contact member 1417.

As the contact member 1417 is moved in a state where the contact member 1417 is positioned adjacent to the first cooling unit 1300, the contact member 1417 is brought into close contact with the first cooling unit 1300, And can be separated from the cooling unit 1300.

The opening and closing member 1418 may be coupled to an end portion of the contact member 1417 and a portion thereof may be opened or closed. The opening and closing member 1418 can open or close one side of the contact member 1417. [

For example, the opening and closing member 1418 may be configured to seal the first transfer unit 1400 from the outside without the first transfer unit 1400 and the first cooling unit 1300 communicating with each other. When the first transfer unit 1400 and the first cooling unit 1300 are in communication with each other, the first transfer unit 1400 can be opened.

The opening and closing member 1418 for this purpose may include, for example, an edge portion 1418a and a door portion 1418b.

The edge portion 1418a may be formed along the edge of the end portion of the contact member 1417. [ The edge 1418a may be, for example, a rectangular frame having a central portion penetrating therethrough. The mold M can be passed through the penetrated portion of the edge portion 1418a.

An impact absorbing member 1418c may be formed on one side of the edge portion 1418a. The impact absorbing member 1418c not only absorbs the impact applied to the edge portion 1418a in the process of the edge portion 1418a and the first cooling unit 1300 being in close contact with each other but also the edge portion 1418a is worn Can be prevented. The material of the shock absorbing member 1418c for this purpose may be, for example, any one selected from rubber, silicone, and plastic, but is not limited to a specific introduction.

The door portion 1418b can be installed so as to be able to move in and out through one side of the edge portion 1418a. For example, the door portion 1418b can be installed to be able to move in and out through the lower side of the edge portion 1418a. The door portion 1418b may be formed in a rectangular plate shape having a relatively smaller size than the edge portion 1418a.

When the penetrated portion of the edge portion 1418a is opened due to the lowering of the door portion 1418b, the mold M can enter and exit through the penetrated portion. When the mold M is completely inserted and removed, 1418b rise to seal the perforated portion of the edge portion 1418a. At this time, the door portion 1418b may be moved by a separate linear motor, but is not limited thereto.

The driving module 1419 can move the contact member 1417 such that the contact member 1417 approaches or leaves the housing 1416. [

For example, in a state where the opening and closing member 1418 and the first cooling unit 1300 are spaced apart from each other, the driving module 1419 moves the contact member 1417 to the first cooling unit 1300, So that the first cooling unit 1300 can be brought into close contact with the first cooling unit 1300. The driving module 1419 for this purpose may be a cylinder whose end portion is coupled to the contact member 1417. [ As an example of the coupling structure of the cylinder and the contact member 1417, a separate bracket formed at the end of the cylinder may be coupled to the upper side of the contact member 1417, but is not limited thereto.

In the glass forming apparatus 1000 including the first transfer unit 1400, the mold M is lifted and lowered in the elevating member 1412 inside the first transfer unit 1400. Therefore, since the entire first transfer unit 1400 is not required to be lifted up, the power consumption can be reduced.

In addition, since the first transfer unit 1400 is not moved in a state where the first transfer unit 1400 is in close contact with the heating unit 1200 or the first cooling unit 1300, It is possible to prevent abrasion from occurring due to friction.

Referring to FIG. 12, the glass forming apparatus according to another embodiment of the present invention may include a first lifting unit 1430.

The first elevating unit 1430 is coupled to one side of the first rotating unit 1420 so that the mold M conveyed by the first conveying unit can be raised and lowered.

In this case, the first transfer unit included in the glass forming apparatus according to another embodiment of the present invention may be one except that the elevating member 1412 (see FIG. 10) is different from the first transfer unit 1400 described above.

In the glass forming apparatus according to another embodiment of the present invention, the entire first transfer unit 1400 is lifted and lowered by the separate first elevating unit 1430, so that the position of the mold M gripped by the gripping member 1411 The lift can be performed. The glass forming apparatus according to another embodiment of the present invention can simplify the structure of the first transfer unit 210 by not providing the elevating member 1412 in the first transfer unit.

12, the first elevating unit 1430 is coupled to the lower end of the first rotating unit 1420. However, the present invention is not limited thereto. That is, the first elevating unit 1430 can be coupled to the upper portion of the first rotating unit 1420, and the first elevating unit 1430 and the first rotating unit 1420 are not coupled to each other, Respectively.

Meanwhile, the first transfer unit 1400 may further include a nitrogen supply unit (not shown).

A nitrogen supply unit (not shown) may be connected to one side of the housing 1416 to supply nitrogen into the housing 1416. Accordingly, it is possible to minimize the contact of the mold M with oxygen during the transfer of the mold M introduced into the first transfer unit 1400 to the first cooling unit 1300. Therefore, the quality of the glass can be improved by preventing the glass from being oxidized.

In the present invention, one or more first transfer units 1400 may be provided. That is, the first transfer units 1400 may be provided in various numbers according to the design, thereby improving the productivity.

The present invention also includes a second cooling unit 1500. The second cooling unit 1500 is for cooling the mold M at a relatively high speed as compared with the first cooling unit 1300. The second cooling unit 1500 may be cooled from the outside in a state of being hermetically sealed from the mold M which is positioned apart from the first cooling unit 1300 and has been primarily cooled through the first cooling unit 1300 Let's do it.

The present invention also includes a second transfer unit 1600 for transferring the mold M that has been firstly cooled in the first cooling unit 1300 from the outside in a sealed state to the second cooling unit 1500 .

Since the second transfer unit 1600 can be applied to the first transfer unit 1400 described above, detailed description thereof will be omitted. A second rotary unit 1620, a nitrogen supply unit (not shown), and the like may be coupled to the second transfer unit 1600 as in the case of the first transfer unit 1400.

The second cooling unit 1500 may include at least one second cooling chamber 1510. The second cooling chamber 1510 may allow cooling of the mold M transferred from the first cooling unit 1300 by the second transfer unit 1600 in a state in which the mold M is hermetically sealed. The second cooling chamber 1510 may be rotated to cool the mold M. [

Referring to FIGS. 1 and 13, the second cooling unit 1500 may include a second rotating plate 1530, a second rotating unit 1540, and a plurality of second cooling chambers 1510, for example.

The second rotating plate 1530 may have a circular shape. The second cooling chamber 1510 may be positioned at the predetermined interval along the edge of the upper surface of the second rotary plate 1530. For example, when the second cooling unit 1500 includes eight second cooling chambers 1510, the second cooling chamber 1510 may have a diameter of about 45 However, the number of the second cooling chambers 1510 is not limited to eight. However, it is preferable that the number of the second cooling chambers 1510 in the present invention is larger than the number of the heating units 1200 in view of the fact that it takes much more time for the cooling process than the heating process in the glass forming process .

The second rotating unit 1540 may be coupled to the second rotating plate 1530 to rotate the second rotating plate 1530. More specifically, the second rotating unit 1540 is coupled to the lower side of the second rotating plate 1530 to rotate the second rotating plate 1530 clockwise or counterclockwise.

During the rotation of the second rotary plate 1530, the mold M can be received in the second cooling chamber 1510 and cooled. It is also possible that the cooling of the mold M proceeds while the rotation of the second rotation plate 1530 is stopped for a predetermined period of time after the rotation of the second rotation plate 1530 by a predetermined angle.

The second cooling chamber 1510 is formed with an inner space for cooling the mold M and an opening and closing door 1520 may be installed on one side of the second cooling chamber 1510 so that the heated mold M can be taken in and out. An actuator for operating the opening / closing door is connected to the opening / closing door 1520.

The opening and closing door 1520 can prevent the nitrogen supplied into the second cooling chamber 1510 from being lost to the atmosphere, thereby reducing the nitrogen consumption amount. Therefore, the use of nitrogen for molding the glass can be minimized, so that the glass molding cost can be reduced.

The first cooling plate 1521a and the second cooling plate 1521b may be vertically spaced apart from each other inside the second cooling chamber 1510. When the mold M is accommodated in the second cooling chamber 1510, at least one of the first cooling plate 1521a and the second cooling plate 1521b is moved to contact the upper side and the lower side of the mold M, The mold M can be cooled.

The cooling method of the mold M may be, for example, a cooling method in which a cooling pipe through which cooling water flows is provided inside the first cooling plate 1521a and the second cooling plate 1521b. Alternatively, a plurality of nozzles may be formed at a portion of the first cooling plate 1521a and the second cooling plate 1521b facing the mold M, and compressed air or water-mist ) To the mold (M), but the present invention is not limited thereto.

Since the glass in the mold M can be uniformly cooled by cooling the mold M while the mold M is wrapped around the second cooling chamber 1510, Can be excellent in quality.

In addition, the mold M is quickly cooled by the first cooling plate 1521a and the second cooling plate 1521b as compared with the conventional glass forming apparatus, so that the tack time can be reduced.

In addition, the second cooling unit 1500 may include a lift module 1524. The elevating module 1524 may be one or more.

The lifting module 1524 is positioned below the second cooling chamber 1510 to lift the second cooling plate 1521b.

Also, although not shown, the elevating module 1524 may be positioned above the second cooling chamber 1510 and be configured to lower the first cooling plate 1521a.

Meanwhile, the second cooling unit 1500 may include a nitrogen supply unit (not shown).

The nitrogen supply unit may be connected to the second cooling chamber 1510 of the second cooling unit 1500 to supply nitrogen into the second cooling chamber 1510. As a result, the inside of the second cooling chamber 1510 becomes a nitrogen atmosphere during the cooling of the mold M, so that the mold M can be cooled more stably.

Hereinafter, the operation of the glass forming apparatus 1000 according to an embodiment of the present invention will be described with reference to the drawings.

After the heating unit 1200 completes the process of heating the mold M, the first rotation unit 1420 rotates the first transfer unit 1400 to rotate the contact unit 1417 included in the first transfer unit 1400 To be positioned adjacent to the heating unit 1200.

Closing member 1418 is opened and the opening and closing door 1261 of the heating unit 1200 is opened when the driving module 1419 brings the contact member 1417 into close contact with the heating unit 1200. [

The support portion 1411a included in the gripping member 1411 can be moved to the lower side of the mold M by the sliding member 1414. [ The gripping member 1411 is lifted by the lifting member 1412 or the first lifting unit 1430 and the sliding member 1414 moves the lifting member 1411 in the direction away from the heating unit 1200. [

Thereafter, the opening and closing door of the opening and closing member 1418 and the heating unit 1200 can be closed. When the drive module 1419 moves the contact member 1417 away from the heating unit 1200, the first rotation unit 1420 rotates the first transfer unit 1400 again by a predetermined angle, To be positioned adjacent to the first cooling unit (1300).

The opening and closing doors of the opening and closing member 1418 and the first cooling chamber 1310 are opened and the sliding member 1414 opens the gripping member 1411 to the first cooling chamber 1310. [ 1 < / RTI >

The lifting member 1412 or the first lifting unit 1430 lower the gripping member 1411 to place the mold M inside the first cooling chamber 1310. [ That is, the mold M heated by the at least one heating unit 1200 can be rapidly transferred to the first cooling unit 1300 by the first transfer unit 1400 and cooled.

Next, the second transfer unit 1600 transfers the mold M primarily cooled in the first cooling chamber 1310 of the first cooling unit 1300 to the second cooling chamber (not shown) of the second cooling unit 1500 1510) to perform secondary cooling. When the mold M is conveyed to the second cooling chamber 1510 and the opening and closing door is closed, the first cooling plate 1521a is lowered or the second cooling plate 1521b is lifted and brought into contact with the mold M Cooling is performed.

At this time, the first rotation unit 1420 rotates the first transfer unit 1400 again a predetermined angle so that the contact member 1417 is positioned adjacent to the other heating unit 1200. Then, the above-described process is repeatedly performed to form the glass.

14 is a view showing a glass molding apparatus according to another embodiment of the present invention. The glass molding apparatus 1000 'according to another embodiment of the present invention has substantially the same configuration as that of the previous embodiment, and only differences from the previous embodiment will be described below.

As shown in FIGS. 14 and 15, the glass forming apparatus 1000 'according to another embodiment of the present invention includes a heat exchange chamber 1350.

The heat exchange chamber 1350 is installed adjacent to the first cooling chamber 1310. In the heat exchange chamber 1350, a glass-loaded unfired mold is accommodated, and the unfired mold is heated to a predetermined temperature by receiving the heat of the mold transferred from the heating unit 1200 to the first cooling chamber 1310. That is, the heat exchange chamber 1350 receives heat from a mold that is primarily cooled in the first cooling chamber 1310 of the first cooling unit 1300 to preheat the unheated mold. In such a heat exchange chamber 1350, it is possible to utilize the waste heat to save energy, and the time for heating the mold in the heating unit 1200 can be shortened by preheating the unheated mold.

As shown in FIGS. 14 and 15, the heat exchange chamber 1350 has an inner space in which the mold is accommodated, and one end thereof is opened so that the mold can be taken in and out. Although the heat exchange chamber 1350 is shown in the lower portion of the first cooling chamber 1310, the heat exchange chamber 1350 may be installed at various positions adjacent to the first cooling chamber.

The construction and operation of the glass forming apparatus 1000 'according to another embodiment of the present invention will be described in more detail as follows. In the following description, the portions overlapping with those described in the preceding embodiments will be omitted.

The mold M that has been heated in the heating unit 1200 is transferred from the Z1 position through the first transfer unit 1400 to the first cooling chamber 1310 of the first cooling unit 1300. In the first cooling chamber 1310, the mold is cooled at room temperature. The first rotating plate 1330 rotates in a clockwise direction to continuously supply the heated mold to the first cooling chamber 1310 of the first cooling unit 1300. The mold cooled in the first cooling unit 1300 is transferred to the second cooling unit 1500 by the second transfer unit 1600 at the Z2 position. The mold cooled at the Z3 position to the first cooling chamber 1510 of the second cooling unit 1500 is transferred.

To this end, a second transfer unit 1600 is coupled with a transfer unit 1700 capable of transferring the second transfer unit 1600.

The mobile unit 1700 may have a length. The second transfer unit 1500 or the second transfer unit 1500 and the second rotation unit 1540 can be moved to various positions along the length direction of the transfer unit 1700 by the transfer unit 1700. [ Although not shown in detail, the moving unit 1700 includes a moving plate on which the LM guide, the second transfer unit 1500 or the second transfer unit 1500 and the second rotating unit 1540 are mounted, However, the present invention is not limited to such an actuator. That is, the moving unit 1700 may be implemented with various structures that can move the second transfer unit 1500 or the second transfer unit 1500 and the second rotation unit 1420 along the length direction.

The second rotating plate 1530 rotates in the clockwise direction to continuously supply the mold that has been firstly cooled in the first cooling unit 1300 to the second cooling chamber 1510 of the second cooling unit 1500. [ The mold cooled in the second cooling unit 1500 is unloaded at the Z4 position. The unloaded mold separates the molded glass inside the mold by an operator or a separate apparatus, and mounts unformed glass. The mold on which the unformed glass is mounted is supplied to the heat exchange chamber 1350 at the Z5 position by an operator or a separate apparatus. The heat exchange chamber on which the unheated mold is mounted is moved by the rotation of the first rotation plate 1330 and is preheated by receiving heat from the mold accommodated in the first cooling chamber 1310. The mold preheated by the heat exchange is transferred to the heating unit 1200 by the first transfer unit 1400 at the Z1 position.

The glass forming apparatus 1000 'according to another embodiment of the present invention repeats the above process to form the glass. The above description is an example, and the glass forming apparatus 1000 'according to another embodiment of the present invention may also be variously modified. For example, the moving unit 1700 may be omitted, and the second transfer unit 1600 may be disposed between the first cooling unit 1300 and the second cooling unit 1500 as in the previous embodiment, The position where the un-heated mold is supplied to the heat exchange chamber, and the like can be variously changed.
