Technical Field

The invention relates to the field of forming furnaces, and provides a forming furnace, in particular to a glass forming furnace.

Background

With the advance of science and technology, many electronic devices successively adopt touch devices to replace the traditional mechanical operating devices, increase the operating space and the size of the display, and provide more intuitive and convenient operating modes, such as devices like smart phones or central control screens of automobiles. Under such a background, the demand of the touch device in different fields is greatly increased, and the glass on the touch device also needs to have different shapes to fit different devices.

At present, glass is manufactured in a shape by placing a plate glass raw material on a mold and heating the mold to soften the glass raw material. And then, the glass raw material is attached to the mold in a negative pressure or mold pressing mode, so that the glass raw material is formed into a shape corresponding to the mold, and the glass assembly with the specific shape can be finished after cooling.

Current glass forming furnaces have several drawbacks as follows:

1. the angle of the pressing is fixed, so the angle of the mold must be accurately controlled, otherwise the pressure is uneven and the forming effect is not good.

2. The sealing effect inside the forming furnace is poor, and oxygen invades the inside of the forming furnace, so that the mold is easy to oxidize to generate unexpected negative effects.

3. The cleaning of the die needs to be manually carried out, and the die needs to be manually cleaned after being formed in order to prevent the die from carrying foreign matters to enter the forming furnace.

Thus, current glass forming furnaces have a number of drawbacks, and it is appreciated by those skilled in the art how to address these drawbacks.

Detailed Description

The present invention provides a glass forming furnace, which has a movable mold pressurizing mechanism, an airtight valve, an automatic cleaning function and other modes, and greatly improves the glass forming efficiency.

Referring to FIG. 1, FIG. 1 is a schematic top view of a glass forming furnace. The glass forming furnace includes a forming section 110, a cleaning section 120, a plurality of sealing doors 130, and a conveyance channel 140. Wherein the delivery channel 140 passes through the forming zone 110 and the cleaning zone 120, and the delivery channel 140 is adapted to transport a plurality of glass forming molds 10. In addition, in one embodiment, the glass forming furnace further comprises a heating zone and a cooling zone (not shown), and the conveying channel 140 sequentially passes through the heating zone, the forming zone 110, the cooling zone, and the cleaning zone 120. And the conveying path is a circulating path that allows the glass-forming mold 10 to continuously pass through the heating zone, the forming zone 110, the cooling zone, and the cleaning zone 120.

In one embodiment, the conveying path 140 further includes a low friction rail 143, and the glass forming mold 10 moves on the low friction rail 143, and the low friction rail 143 allows the glass forming mold 10 to move more smoothly, and the low friction force can reduce dust generated by the glass forming mold 10 due to friction.

The heating zone is to heat the glass forming mold, and then the glass forming mold enters the forming zone to perform high-pressure forming. Thus, the forming zone further comprises at least one pressure device 200. Referring to fig. 2A, fig. 2A is a schematic diagram of a pressure device. The pressing device 200 includes a servo motor 201, a pressing rod 210 and a mold pressing mechanism 220. The servo motor 201 is connected to the pressure ram 210, preferably via a screw, so that the rotation of the servo motor 201 can drive the pressure ram 210 to move up and down. One end of the pressure push rod 210 includes an end notch 212 and an embedded structure 211.

In one embodiment, the pressure device 200 further comprises a sleeve structure 230 and a spring 231. The sleeve structure 230 is disposed around the pressure rod 210, i.e. the pressure rod 210 passes through the sleeve structure 230. The spring 231 is disposed on the sleeve structure 230 and connected to the pressure ram 210. The spring 231 is provided to make the control of the pressure ram 210 by the servo motor 201 smoother.

Referring to fig. 2B, fig. 2B is a schematic view of the pressure push rod. The end notch 212 is disposed at one end of the pressure ram 210 and at the end connected to the pressurizing structure 220. In the present embodiment, the pressure ram 210 is cylindrical, and the end notch 212 is a semicircular notch and occupies a certain area of the cross section of the pressure ram 210.

The insert 211 is composed of a neck portion 2111 and a head portion 2112, and the diameter of the neck portion 2111 is smaller than that of the head portion 2112, so that the insert 211 forms a mushroom-shaped structure at the end where the pressure ram 210 is connected to the mold pressurization mechanism 220. Adapted to fit into the insertion notches 221 in the mold press 220.

Referring to fig. 2C and 2D, fig. 2C and 2D are schematic diagrams illustrating a mold pressing mechanism and a fixed plug. The mold pressing mechanism 220 has a disk shape and a certain thickness, and the mold pressing mechanism 220 is adapted to contact the glass forming mold 10. The mold pressing mechanism 220 has an insertion notch 221 and a fixing notch 222 at the center, and the insertion notch 221 is connected to the insertion structure 211 of the pressing ram 210.

Referring to fig. 3A to 3D, fig. 3A to 3D are schematic diagrams illustrating connection between a pressure link and a mold pressing mechanism. When assembled, the insert structure 221 of the pressure ram 210 extends from the retention notch 222, and then the neck portion 2111 of the insert structure 211 extends into the insert notch 221 (fig. 3A). Since the head 2112 of the insertion structure 211 has a larger diameter, the pressure plunger 210 is engaged with the insertion notch 221 and cannot be pulled out upward (fig. 3B). Next, the fixing plug 223 is inserted into the fixing notch 222 (fig. 3C), and the fixing plug 223 has a shape corresponding to the fixing notch 222, so that the fixing plug 223 can be closely inserted into the fixing notch 222 while fixing the pressure push rod 210. At this time, due to the end point notch 212 on the pressure push rod 210 and the arc-shaped structure on the embedding notch 221, the mold pressing mechanism 220 can swing (fig. 3D), so that the mold pressing mechanism 220 can adapt to glass forming molds 10 placed at different angles.

Referring to fig. 5, fig. 5 is a schematic diagram of a cleaning region. The cleaning region 120 is adapted to clean the glass forming mold 10, and therefore the cleaning region 120 further includes an active brush mechanism 142 adapted to brush away dust or foreign matter on the glass forming mold 10. In one embodiment, the conveying path 140 in the cleaning region 120 further includes a cleaning hole 141, and the active brush mechanism 142 is disposed in the cleaning hole 141. That is, the glass-forming mold 10 passes through the cleaning zone 120 from the conveying path 140, and passes over the active brush arrangement 142, so that the active brush arrangement 142 cleans the glass-forming mold 10.

With continued reference to FIG. 1, the glass forming furnace further includes a plurality of sealing doors 130, the sealing doors 130 being disposed at an inlet and an outlet of the forming section 110. The sealing sub-gate 130 is provided to maintain the pressure inside the forming zone 110 and prevent foreign materials or oxygen from entering the forming zone 110. In one embodiment, the forming section 110 is filled with nitrogen to prevent oxidation of the glass forming mold 10 by exposure to oxygen at elevated temperatures. And a relatively high pressure is established in the forming zone 110, external oxygen does not enter the forming zone 110 as the sealing door 130 opens to allow the glass forming furnace 10 to pass.

Referring to fig. 4A, fig. 4A is a schematic view of the sealing door. The sealing door 130 includes a valve 132 and a sealing structure 131. Wherein the cross-sectional thickness of the valve 132 decreases from top to bottom. I.e., from the side, the valve 132 is a U-shape. The sealing structure 131 is composed of two symmetrical parts, so that a U-shaped groove 133 is formed on the sealing structure 131, and the shape of the groove 133 is corresponding to the shape of the valve 132, so that the valve 132 can be inserted into the groove 133. The sealing structure 131 further includes a through hole 134, and the through hole 134 allows the glass forming mold 10 to pass through when the sealing door 130 is opened, and closes the through hole 134 when the sealing door 130 is closed. Allowing the valve 132 and seal 133 to close the perforations 134 produces a seal. Especially, the U-shaped valve 132 and the groove 133 can increase the sealing performance.

Referring to fig. 4B, a schematic view of the valve and the sealing structure shown in fig. 4B is shown. The symmetrical structure of the sealing structure 131 forms a groove 133, and the shape of the groove 133 corresponds to the shape of the valve 132, so that the valve 132 can be inserted into the groove 133 to close the perforation 134.

The glass forming furnace 100 of the present creation improves the drawbacks of conventional glass forming furnaces by a number of improvements. The pressure device 200 is provided with a mold pressing mechanism 220 which can swing, so that when the mold pressing mechanism 220 presses the glass forming mold 10, the glass forming mold 10 can adapt to glass forming molds 10 arranged at different angles, and the glass forming mold 10 can bear more even pressure. The sectional thickness of the sealing door 130 of the U-shaped design, the valve 132 of the sealing door 130, decreases progressively from top to bottom, thus providing a better sealing effect when the sealing door 130 is closed, maintaining the pressure inside the forming region 110, and isolating external foreign objects. The cleaning region 120 is provided with an active brush mechanism 142, and the glass forming mold 10 after being formed is automatically cleaned by the active brush mechanism 142 when passing through the cleaning region 120, so that the manual operation is reduced, and the glass forming mold 10 is improved. By the improved design, the forming efficiency and yield of the glass forming furnace 100 can be greatly improved, the service life of the mold can be prolonged, and the labor cost can be reduced.

The above-described embodiments are merely exemplary for convenience of description, and various modifications may be made by those skilled in the art without departing from the scope of the invention as claimed in the claims.
