The present invention relates to a molding apparatus for glass molding which shortens the molding time by allowing the lid to enter between the heating furnace and the molding furnace when the heating furnace completes heating, thereby moving the molding furnace immediately to heat the other heating furnace. will be.

In the conventional glass molding apparatus, the glass to be molded is placed in the molding mold installed in the molding furnace, and the heating furnace which is lifted by the crane is lowered and covered on the molding furnace, and then heated. When the heating is completed, the glass molding apparatus is left as it is. Wait for the cooling (slow cooling) slowly, and when the cooling is completed, raise the furnace to open the forming furnace, lift the formed glass, and put another glass to heat it. In order to have a problem to wait for the cooling time.

In other words, immediately after the heating is completed, the heating furnace is raised immediately to open the forming furnace, so that the heated glass is quenched and cracked, so the heating furnace is raised to open the forming furnace, lifted the formed glass, put another glass, and the next heating starts. As a result, the average cooling time of the glass heated to 620 ° C and about 50 minutes and the time to put the next glass was settled.

In order to solve this problem, the present invention is to install the rails on both sides of the forming furnace and to move the heating furnace on the rail, and at the same time to raise and lower the heating furnace by hydraulic cylinder, and the forming furnace cover made of heat-resistant material to open and close the molding furnace. As described in detail according to the accompanying drawings as follows.

1 is a schematic block diagram of a molding furnace (A) (B) (C) (D) (E) at regular intervals, molding furnace (A) (B) (C) (D) (E Rails 2 are provided on both sides.

On the rail 2, the wheels 18 fixed to the lower end of the hydraulic cylinder 4 are slidably placed, and the upper end of the piston 20 of the hydraulic cylinder 18 is fixed to protrude from the side of a conventional gas heating furnace 6. By being fixed on the piece 22, the gas-heated furnace 6 is capable of traveling along the rails 2 by the driving wheel 18, and the gas-heated furnace 6 is the piston of the hydraulic cylinder 18. 20) It is configured to move up and down from the forming furnaces A, B, C, D and E by operation.

A gas supply pipe 6 'is provided on the bottom surface of the gas heating furnace 6 so that gas is supplied and ignited through the gas supply pipe 6', thereby forming the molding furnace (A) (B) (C) (D). (E) It heats up inside.

Molding furnace (A) (B) (C) (D) (E) Both side portions are welded with an "L" type guide rail 8 and a cover 34 with wheels 34 mounted on the guide rail 8. ) And the wheels 34 fixed to the bottom of the cover 30 are allowed to travel on the forming furnaces (A) (B) (C) (D) (E) along the guide rails 8, wherein the cover ( 30 is the metal mesh 26 is placed on the upper and lower sides of the asbestos 24, and then the edge of the metal mesh 26 is fixed with a fixed frame 28, and the cover 30 has several array tubes 32 for heat dissipation. Is installed.

A cover piece of constant width made of non-combustible material is provided on both sides of the cover 30 installed to run along the guide rail 8 fixed to both sides of the forming furnace (A) (B) (C) (D) (E). ) Is configured to protrude downward to close a small gap formed to facilitate the movement of the cover 30 between the cover 30 and the molding furnace (A) (B) (C) (D) (E). .

On one side of the molding furnace (A) (B) (C) (D) (E), there is a rotary opening and closing door 12 for putting glass in and out of the molding furnace (A) (B) (C) (D) (E) As shown in FIG. 2, a conventional glass molding frame (A) is placed, and a refractory brick (14) is laid on the bottom, and an inner wall (16) such as asbestos is fixed to the inner wall.

Reference numeral 40 denotes a gas flame injected into the injection hole of the heating furnace, 42 is glass, 44 is a heat insulating fixing nail, 46 is an exhaust pipe, and 48 is a door lock.

The present invention configured as described above allows the glass 42 to be placed in the forming mold (a) of the forming furnace (A) through the opening and closing door (12), and moves the heating furnace (6) to be positioned directly above the forming furnace (A) and the hydraulic cylinder. The piston 20 of (4) is lowered so that the heating furnace 6 is covered with the upper part of the forming furnace A as shown in FIG. 4, and then the heating furnace 6 is operated to inject the gas flame into the injection hole. The forming furnace A is heated by 40, and the heating time varies depending on the conditions of the glass 42, but is usually heated for about 120 minutes at a temperature of about 620 ° C.

When the heating is completed, the space is formed so that the cover 30 can enter between the heating furnace 6 and the forming furnace (a) by raising the heating furnace 6 by using the piston 20 of the hydraulic cylinder 4. As shown in FIG. 6, the cover 30 is moved along the guide rails 8 fixed to both sides of the molding furnace E, A, so that the lid 30 is formed instead of the heating furnace 6 as shown in FIG. Overwrite (a).

Asbestos cover pieces 36 are blocked on both sides of the cover 30 between the gaps formed between the cover 30 and the forming furnace A so as not to rub against the upper surface of the forming furnace A when the cover 30 is moved. Through the heat is prevented from being radiated.

Raising the row 6 and moving the lid 30 to open the forming furnace A between the lids, but the temporary forming furnace A opens between the lids, but the glass 42 is extremely short compared to the total cooling time (about 50 minutes). Since the heat dissipation due to the opening at that moment does not cause any trouble such as cracks in the glass 42 at all, it promotes faster cooling. When the cover 30 is covered in the opening of the forming furnace A, The heat is slowly cooled through several array tubes 32 formed in the cover 30.

When the lid 30 is moved to cover the opening of the molding furnace A, the heating furnace 6 is immediately moved to heat the next molding furnace B in the same manner, and when the heating is completed, the lid 30 is moved to the molding furnace. When the heating furnace 6 is moved again while covering (B), heating is continuously performed by heating another forming furnace (C).

Therefore, the present invention waits for about 50 minutes for the cooling time of the furnace to remain in the cover state even after the heating is completed as before, and when the cooling is completed, the glass is lifted up and the new glass is settled. Unlike the related art, the heating furnace 6 heats continuously without waiting for cooling, thereby shortening a lot of molding time and increasing productivity.
