Referring to the structure of an embodiment shown in Figure 1, Figure 2 and Figure 5, the multi-mold hot bending forming equipment includes a feeding device 1 (see the structure shown in Figure 2) and a heating channel 2 that are sealed and connected in sequence. Device 3 (see the structure shown in FIG. 1), a molding device 5 with a molding channel 4 (see the structure shown in FIG. 1), an annealing device 7 with an annealing channel 6 (see the structure shown in FIG. 1), and The discharging device 9 of the material channel 8 (see the structure shown in FIG. 5), the feeding device 1 includes a feeding isolation bin 10 and a pushing unit 11, and the feeding isolation bin 10 is formed along with the pushing unit 11 The cloth channel 12 extends in the push direction (left and right direction of the graphical interface in Figure 2) perpendicular to the cloth direction (left and right direction of the graphical interface in Figures 3 and 4). Mold positioning position, heating channel 2 has corresponding multiple heating positions, molding channel 4 has corresponding multiple molding positions (for example, six heating positions shown in Figure 3, six molding positions shown in Figure 4 Correspondingly, there are six mold positioning positions in the cloth channel 12), and along the material pushing direction, the mold positioning positions, heating positions, and forming positions can communicate and can communicate with the annealing channel 6 and the discharge channel 8. The unit 11 is configured to push the mold arranged in the mold positioning position to the corresponding heating position in the heating channel 2.

In this technical solution, since the feeding isolation bin 10 is formed with a cloth channel 12 extending along the cloth direction perpendicular to the pushing direction of the material pushing unit 11, and the cloth channel 12 has a plurality of cloth channels arranged at intervals along the cloth direction. The mold positioning position, the heating channel 2 has multiple corresponding heating positions, and the molding channel 4 has multiple corresponding molding positions. At the same time, the positioning positions, heating positions, and molding positions of each mold can be communicated, so that the operator can A plurality of forming molds 30 loaded with glass sheets are positioned in the cloth channel 12 along the cloth direction. After deoxygenation treatment in the feed isolation bin 10, the pushing unit 11 can push each forming mold 30 along the pushing direction. Enter the subsequent respective corresponding heating positions and molding positions for subsequent processing, and can be pushed into the annealing channel 6, and finally discharged from the discharge channel 8. Therefore, the multi-mold hot bending molding equipment can perform multiple moldings at a time The processing of the mold 30 significantly improves the equipment operating cycle time, thereby achieving the purpose of increasing the production capacity of a single equipment, and at the same time improving equipment production efficiency, glass molding quality and product yield.

It should be understood that, in the multi-mold hot bending forming equipment of the present invention, the pushing unit 11 can push the mold arranged at the mold positioning position to the corresponding heating position in the heating channel 2 in various ways. For example, in one form, a plurality of corresponding pushing units 11, such as pushing cylinders, are arranged along the cloth direction. Each pushing unit 11 can push its corresponding forming mold 30 to the corresponding heating unit with a certain time difference. Location.

Alternatively, the pushing unit 11 is configured to simultaneously push each mold arranged at each mold positioning position to the corresponding heating position in the heating channel 2 and can push the next mold along the pushing direction by the previous mold. Each mold is pushed at the same time, that is, the advancement of the molding mold 30 is driven by the molding mold 30 at the back, and the pushing unit 11 is only responsible for estimating the newly inserted molding mold 30 in the future. In this way, the prior art is omitted. The shift fork used to push the forming mold 30 to move forward makes the multi-die hot bending forming device of the present invention simple in structure and reduces the failure rate of the device.

Of course, the pushing unit 11 can be multiple and can be arranged in the feeding isolation bin 10, or, in order to reduce the volume of the feeding isolation bin 10, it is convenient to control multiple molding dies 30 to be simultaneously pushed into their corresponding heating positions. Above, preferably, as shown in FIG. 2, the pushing unit 11 includes a pushing plate 13 and a feeding pushing cylinder 14, wherein the cylinder of the feeding pushing cylinder 14 is arranged outside the feeding isolation bin 10 and the pushing rod extends Into the cloth channel 12, of course, the push rod and the wall of the feeding isolation bin 10 are sealed and slidingly fitted, and the push plate 13 is connected to the push rod and extends along the cloth channel 12 to each mold positioning position. In this way, after the finished mold 30 is arranged at each mold positioning position, the push rod of the feeding push cylinder 14 extends, and all the molding molds 30 are pushed into the heating channel 2 at one time through the push plate 13 to the respective heating positions. on.

In addition, in order to facilitate the feeding of the forming mold 30 after deoxygenation in the isolation bin 10 is smoothly pushed into the heating channel 2, preferably, as shown in FIG. 2, between the feeding device 1 and the heating device 3 A mold pushing transition plate 15 is provided; the feeding device 1 includes a receiving plate 16 with a plurality of mold positioning positions, and the receiving plate 16 is detachably arranged in the feeding isolation bin 10; the receiving plate 16 is placed in When the material is fed into the isolation bin 10, the receiving plate 16 and the mold pushing transition plate 15 are flush; for example, the side wall of the material feeding isolation bin 10 is formed with a discharge port with a closed door, and the mold pushing transition plate 15 is isolated from the feed The inside of the bin 10 extends through the discharge port to the outside, for example, can extend into the heating channel 2. Of course, the exposed part of the mold pushing transition plate 15 is covered by a protective cover to prevent the molding mold 30 from contacting the outside air. In this way, the operation The personnel can draw out the material-bearing plate 16 and place the forming mold 30 at the position of the mold and insert it into the feeding isolation bin 10. At this time, the material-bearing plate 16 and the mold pushing transition plate 15 are flush, and the discharge port After the closed door is opened, the pushing unit 11 can smoothly push the forming mold 30 through the mold pushing transition plate 15 from the discharge port and push it into the heating channel 2; and/or, as shown in FIG. Toward the material pushing direction, the multi-die hot bending forming equipment is formed with a material pushing guide groove 29 starting from the mold positioning position of the cloth channel 12 and extending through the corresponding heating position, forming position, and annealing position of the annealing channel 6. For example, the side walls of the heating channel 2, the forming channel 4 and the annealing channel 6 are formed with notches, and each channel is formed with a guide wall extending along the pushing direction. The two guide walls and the notches will form a pushing guide groove 29. With the pushing guide groove 29, the pushing unit 11 can push each forming mold 30 through the heating position, the forming position and the annealing position in an orderly manner to avoid jamming due to mutual interference.

In addition, in order to reduce the surface defects of the glass and improve the molding quality of the glass, preferably, as shown in FIG. 2, the feeding device 1 includes a feeding driving device 17 and an isolation cover 18 located in the feeding isolation bin 10, and the isolation cover A vent interface is formed on the 18, and the feed driving device 17 can drive the isolation cover 18 to switch between the isolation state that seals the mold positioning position and the non-isolation state that is away from the mold positioning position. In this way, because the isolation cover 18 is located in the feed isolation bin 10 and has an isolation state that seals the mold positioning position, in actual use, a well-sealed molding mold 30 (such as the prior art A molding mold without a ventilation slot) is placed on the positioning position of the mold, and then inert gas is injected into the feed isolation bin 10 to replace the air in the feed isolation bin 10, and an isolation cover is used in the feed isolation bin 10 18 Seal the forming mold 30 to form an isolated sealed space, and then use an external vacuum device to evacuate the isolated sealed space through a venting interface to exhaust the air in the isolated sealed space, the air that is not easily removed from the cavity of the forming mold 30, and the forming mold The oxygen in the gap 30, and at the same time, the dust on the glass surface of the forming mold 30 due to electrostatic adsorption is also taken away by vacuum, so as to exhaust the oxygen in the forming mold 30 as much as possible, and then it can be supplemented by external air The device is filled with inert gas through the vent interface. At the same time, since the forming mold 30 is relatively sealed, the amount of gas exchange between the inside and outside of the forming mold 30 is relatively small. In the subsequent operations, the air dust generated by the supplementary inert gas such as nitrogen flow adheres to the glass and mold surface It reduces the surface defects caused by the glass and improves the quality of glass molding.

In the multi-mold hot bending forming equipment of the present invention, a variety of methods can be used to draw vacuum through the ventilating interface and inject inert gas into the isolated sealed space. For example, in one method, the feed drive device 17 drives the isolation cover 18 in the isolated state and To switch between non-isolated states, an additional flexible tube can pass through the wall of the feed isolation bin 10 and be connected to the vent interface. One end of the flexible tube can be connected to the vent interface, and the other end can be connected to the external air supply through a conversion joint. The device is connected with the vacuuming device, so that in the isolated state, the conversion joint connects the vacuuming device and the flexible tube for vacuuming. After the vacuuming is completed, the conversion joint connects the gas supplementing device and the flexible tube to fill in inert gas.

Or, in another way, the connection structure between the feed drive device 17 and the isolation cover 18 can be used for vacuuming and air supplementation. For example, referring to the structure shown in FIG. 2, the feed drive device 17 drives the isolation through a connecting pipe. The cover 18 is switched between the isolated state and the non-isolated state, and one end of the connecting pipe is connected to the vent interface. In this way, the feed driving device 17 can only drive the isolation cover 18 through the connecting pipe. At the same time, the connecting pipe can be used as a vacuum tube and Supplement the trachea.

Of course, the feeding drive device 17 can be arranged at any suitable position. For example, the feeding drive device 17 can be arranged in the feeding isolation bin 10 and fixedly arranged on the top wall of the bin, or, as shown in FIG. 2, The feed driving device 17 is fixedly arranged on the outside of the top wall of the feed isolation bin 10, and the connecting pipe passes through the top wall of the bin and is in a sealed sliding fit with the top wall of the bin. In this way, the feed driving device 17 can drive the isolation cover 18 to fall through the connecting pipe to contact the bottom wall of the feed isolation bin 10 to be in an isolated state, or drive the isolation cover 18 to rise away from the bottom wall of the bin to be in a non-isolated state.

Further, in order to improve the convenience of the connection between the feeding drive device 17 and the connecting pipe, and to improve the reliability of the movement of the connecting pipe, preferably, as shown in FIG. 2, the power output end of the feeding drive device 17 is connected with an end plate 34 , The connecting pipe is fixedly arranged on the end plate 34. Another perspective structure of the arrangement relationship between the end plate 34 and the connecting pipe in FIG. 2 can refer to the arrangement relationship between the end plate 34 and the inlet pipe 26 and the outlet pipe 27 shown in FIG. 5. In this way, one end of the connecting pipe is connected to the vent interface on the isolation cover 18, and the other end extends from the end plate 34 for connecting an external air supplement device and a vacuum device.

The arrangement of the end plate 34 also facilitates the connection of multiple pipes with the isolation cover 18. For example, as shown in FIG. 2, in order to improve the convenience of vacuuming and injecting inert gas, the connecting pipe includes an inlet pipe 19 and an outlet pipe 20. The arrangement structure of the end plate 34 and the air inlet pipe 19 and the air outlet pipe 20 in Fig. 2 can refer to the arrangement structure of the end plate 34 and the water inlet pipe 26 and the water outlet pipe 27 shown in Fig. 5. The two are basically the same. The air interface includes an air inlet. And the exhaust port, wherein the feed drive device 17 is arranged outside the feed isolation bin 10 and is connected to the isolation cover 18 through the air inlet pipe 19 and the air outlet pipe 20. The air inlet pipe 19 and the air outlet pipe 20 are sealed and slidingly connected to the inlet The top silo wall of the material isolation silo 10 is matched with the air inlet and the air outlet respectively. In this way, in the isolated state, inert gas with static elimination function can be injected into the isolated sealed space through the air inlet pipe 19 and the air inlet, and then vacuum is drawn through the air outlet pipe 20 and the exhaust port, and then the air inlet pipe 19 and Inject inert gas into the gas inlet.

Of course, the feeding driving device 17 may have various forms. For example, the feeding driving device 17 may be an air cylinder. As shown in FIG. 2, an end plate 34 is connected to the piston rod of the air cylinder. Alternatively, the feeding drive device 17 includes a lifting rod and a locking mechanism provided between the lifting rod and the feeding isolation bin 10. The locking mechanism includes a locking handle. Lifting the lifting rod upward can make the isolation cover 18 in a non-isolated state. Moving the pull rod downward can make the isolation cover 18 contact the bottom wall of the warehouse and be locked by the locking mechanism, so that the isolation cover 18 is in an isolation state.

In addition, a corresponding number of mold positioning positions can be set in the feeding isolation bin 10 as required. For example, a plurality of mold positioning positions spaced apart along the cloth direction perpendicular to the pushing direction are formed in the feeding isolation bin 10 , The isolation cover 18 can simultaneously seal a plurality of mold positioning positions. In this way, through a single isolation cover 18, it is possible to perform deoxidation and dust removal operations on multiple molding dies 30 at the same time.

In addition, as shown in FIG. 1, the heating device 3, the forming device 5, and the annealing device 7 respectively include a plurality of heating channels 2, a forming channel 4, and an annealing channel 6, and are arranged along the pushing direction, that is, the heating device 3 The forming mold 30 can be preheated, the forming device 5 can be hot bending the forming mold 30, and the annealing device 7 can anneal the hot bending forming mold 30; in this way, the multi-mold hot bending forming equipment includes a glass mold preheating area, hot bending Forming area, annealing cooling area. A total of 11-20 station units can be set according to the production process requirements, of which 4-12 station units can be set up in the preheating area, 2 to 4 station units can be set up in the forming area, and 3 to 8 station units can be set up in the annealing cooling area In the station unit, 6 mold channels are arranged in parallel to form a six-mold hot-bending forming equipment, which enables the six forming molds 30 to perform hot-bending simultaneously.

The six-die hot bending equipment preferably has a total of 13 station units, of which 7 station units are installed in the preheating area, 3 station units are installed in the hot bending forming area, and 3 station units are installed in the annealing cooling area.

The seven preheating stations of the glass mold in the preheating zone can heat the glass mold from room temperature to about 700 degrees to meet the glass deformation temperature. For example, after a fixed period of time, the forming mold 30 moves from the previous heating station to the next heating station for heating. After continuous heating, the forming mold 30 enters the seventh heating station. It will be heated to about 700 degrees. At this time, the glass in the forming mold 30 reaches the softening point temperature, and the forming mold 30 enters the hot bending forming area. As shown in FIG. 3, the upper heating plate adopts a liftable structure. When the forming mold 30 moves to the heating station, the upper heating plate is lowered to a contact position with the upper surface of the forming mold 30 to improve heating efficiency. The three channels on the left side of the upper heating plate are a group and the three channels on the right side are a group. The connecting plate 31 is used for connection, and the lifting cylinder drives the connecting plate 31 to rise and fall to move the heating plate up and down.

The three stations of the press forming area of the hot bending forming area adopt proportional valves to control the cylinder lifting and pressurizing mold forming, each proportional valve controls a cylinder, and each station has three cylinders into a group, as shown in Figure 4, forming The mold 30 enters the first station forming station at about 700 degrees, and performs compression molding. The molding pressure is specifically determined according to parameters such as temperature and glass performance. The pressure range is about 1000N~2000N. The forming mold 30 is in the first station. After forming at the forming station, enter the next forming station to continue pressurizing and shaping. Each molding channel 4 in the molding area is equipped with a molding cylinder to ensure that there is enough pressure to heat-bend the glass during molding. At the same time, the three cylinders on the left are a group and the three cylinders on the right are a group. A basically synchronous connecting rod 32 is provided. The connecting rod 32 is a cross-teeth plug-in structure to ensure that the forming cylinders are synchronized and linked, and the forming accuracy of each forming cylinder will not affect each other. A position detector 33 is installed on each forming cylinder to accurately determine and control the position of the forming cylinder, which will significantly improve the quality of glass forming in the forming mold 30.

During hot bending, a heating tube is used for heating, and the highest temperature can be above 800 degrees to meet the glass hot bending temperature. The heating method is to heat the heating plate through a heating tube. The heating plate is made of silicon carbide plate. The silicon carbide has good thermal conductivity. At the same time, the coefficient of thermal expansion is small, the heating is not deformed, and the strength is high. Then the heating plate supports the forming mold 30 to form The mold 30 is heated, and the heating plate serves as a carrier for heating and supporting the molding mold 30 so as to have good stability and thermal uniformity, and help the glass molding in the molding mold 30. At the same time, there is a heat insulation board on the outside of the heating plate. The heat insulation board is made of refractory material, which has high temperature resistance, heat preservation and heat insulation, and protects the surrounding components while reducing heat loss. In addition, outside the hot bending forming area, such as the furnace body is covered with insulation materials, the upper insulation board, the lower insulation board, and the side insulation board. The furnace body insulation layer effectively prevents the heat loss in the furnace, reduces heat loss and reduces energy consumption.

During press molding, the mold is heated by heating plates, and a single station uses six cylinders to drive six heating plates up and down. A cylinder stroke detection system is installed during the molding process to monitor the glass molding state.

There are three work stations for slow cooling and shaping in the annealing cooling zone, and the glass is cooled and shaped near the annealing point. After the forming mold 30 is formed and finalized in the forming area, it enters the annealing area to begin the annealing stress relief process. After three annealing station units, the temperature of the forming mold 30 gradually decreases, and the glass temperature in the forming mold 30 also decreases. The temperature is lowered from the softening point to below the annealing point, annealing is completed, and then the discharging isolation bin 22 of the discharging device 9 is entered from the forming furnace.

and / or,
