Description

Technical Field

[0001] The invention relates to the technical field of glass pressing, in particular to an energy-saving, high-precision, heat-resistant and constant-temperature glass molding automatic forming machine. Background Art

[0002] Glass compression molding technology is an advanced production process that places softened glass into a high-precision mold. Under certain temperature, pressure, and specific atmosphere conditions, the glass is shaped according to the shape and size of the mold. After cooling and solidification, a glass product with a specific shape and precision is formed. The specific steps are as follows:

[0003] First, select suitable glass raw materials, such as sand, lime, soda, etc., mix them in a certain proportion and put them into a furnace, heat them to about 1500C-1600℃, melt them into uniform liquid glass, and then draw the molten glass from the furnace and form glass drops of a certain mass and shape through a feeding device. Then, put the glass drops into the preheated mold of the molding machine, and then apply pressure to the mold through a pressure device to make the glass drops flow in the mold and fill the mold cavity to form a shape consistent with the mold cavity. Finally, while maintaining the pressure, cool the mold to solidify the glass product. That is, when the glass temperature drops below its transition point, open the mold and take out the formed glass product.

[0004] The finished glass products are then cut and edged, softened by heating, rapidly cooled with high-pressure cold air, and finally annealed to eliminate internal stress and make the glass more stable. This results in tempered glass with impact resistance and bending strength 4-5 times higher than ordinary glass. The tempered glass is widely used in aerospace, shipbuilding, automotive, construction and other fields.

[0005] However, in existing glass compression molding devices, the molding mold is mostly fixed to the molding device by bolts. This fixing method requires that after the molding process is completed, in order to ensure the quality of the glass product, the molding mold needs to maintain a stable pressure on the molding device and slowly cool down. This operation is necessary because if the glass has a local cooling speed that is too fast or the cooling speed is inconsistent, it will form an uneven stress distribution inside the glass. This uneven stress distribution will greatly increase the risk of glass breakage and seriously affect the yield of glass products. Moreover, the slow cooling process of the molding mold on the molding device greatly affects the working efficiency of the compression molding machine. Especially in the current pursuit of efficient production, this situation is obviously not conducive to the smooth progress of production and makes it difficult to effectively improve production efficiency.

[0006] In view of this, in order to overcome the above technical problems, the present invention proposes an energy-saving, high-precision, heat-resistant and constant-temperature glass molding automatic forming machine to solve the above technical problems. Summary of the Invention

[0032] As an embodiment of the present invention, a threaded groove 114 is formed at the lower end of the heating box 112; a threaded rod 115 that matches the threaded groove 114 is fixedly connected to the upper end of the hydraulic push rod 113; and the inner wall of the heating box 112 is coated with a graphite coating.

[0035] During operation, for existing glass compression molding devices, the molding molds are mostly fixed to the molding device by bolts. This fixing method requires that after the molding process is completed, in order to ensure the quality of the glass products, the molding molds need to maintain stable pressure on the molding device and cool slowly. The reason for this operation is that once the glass has a local cooling speed that is too fast or the cooling speed is inconsistent, an uneven stress distribution will be formed inside it, and this uneven stress distribution will greatly increase the risk of glass breakage and seriously affect the yield of glass products. However, the process of slow cooling of the molding mold on the molding device greatly affects the working efficiency of the compression molding machine. Especially in the current pursuit of efficient production, such a situation is obviously not conducive to the smooth progress of production, making it difficult to effectively improve production efficiency.

[0036] In this regard, the present invention provides a heating box 112 so that the pressing mold 12 can be flexibly installed in the heating box 112 for glass molding operations. After the molding is completed, the pressing mold 12 in the heating box 112 is directly taken out and cooled. On the one hand, there is no need to wait for the mold to cool down, and the next round of molding can be carried out immediately, realizing parallel operation of multiple sets of molds, greatly shortening the production cycle, and significantly improving the overall work efficiency of the molding machine. On the other hand, when facing the production needs of glass products of different specifications and shapes, there is no need to carry out the tedious bolt disassembly process, so that the staff can complete the mold replacement in a short time, making production more flexible and changeable, thereby meeting the diversified needs of the market.

[0037] In the initial state, the electromagnetic plate 154 is in the power-off state, and conveying devices are installed on both sides of the turntable 11, that is, the drive motor 111 drives the turntable 11 to rotate, so that the turntable 11 starts to rotate relative to the base 1, so that the turntable 11 drives the guide rod 14 to rotate to the conveying device on its left side. At this time, the user controls the servo motor 15 to operate. Since the output shaft of the servo motor 15 is provided with a rectangular groove 152, and the bevel gear shaft 151 located in the rectangular groove 152 is pushed by the transmission spring 153 and extends out of the rectangular groove 152, the bevel gear shaft 151 is engaged with the bevel gear ring 142, and since the bevel gear ring 142 is fixedly connected to one end of the rotating rod 141, the servo motor 15 is in operation. During the operation of 15, the servo motor 15 can drive the bevel gear ring 142 to rotate through the bevel gear shaft 151, so that the bevel gear ring 142 can drive the rotating rod 141 fixed to it to rotate synchronously, so that the rotating rod 141 drives the guide rod 14 slidingly connected on its surface to rotate upward until the guide rod 14 rotates to a horizontal state. At this time, the servo motor 15 stops. At this time, the horizontal guide rod 14 contacts the conveying device on the left side of the turntable 11. The conveying device on the left side of the turntable 11 conveys the pressing mold 12 to the upper end of the guide rod 14, so that the pressing mold 12 slides along the upper end surface of the guide rod 14. At this time, the guide rod 14 supports and guides the pressing mold 12.

[0038] The conveying device on the left side of the turntable 11 conveys the pressing mold 12 to the guide rod 14, so that the pressing mold 12 moves along the guide rod 14 until it contacts the turntable 11, that is, the upper mold 121 of the pressing mold 12 contacts the turntable 11. At this time, the pressing mold 12 blocked by the turntable 11 is stably located on the guide rod 14, so that the pressing mold 12 is located directly below the heating box 112. At the same time, the hydraulic push rod 113 is controlled to extend so that the hydraulic push rod 113 can push the heating box 112 to rise and approach the lower mold 122, so that the lower mold 122 continuously enters the heating box 112 until the lower end surface of the lower mold 122 The bottom of the heating box 112 is in contact with the bottom of the heating box 112. Since a resistance heater is installed in the heating box 112, the lower mold 122 entering the heating box 112 is in direct contact with the resistance heater. At the same time, the hydraulic cylinder 131 extends, so that the hydraulic cylinder 131 pushes the connecting rod 132 in the lower connecting groove 133 to descend. Since the upper mold 121 of the pressing mold 12 is installed with a T-shaped plate, when the hydraulic cylinder 131 pushes the connecting rod 132 and the positioning rod 135 to descend, since the positioning rod 135 is located in the positioning groove 134 and the positioning rod 135 is located below the connecting rod 132, the hydraulic cylinder 131 will first push The positioning rod 135 moves downward from both sides of the T-plate, and then the connecting rod 132 contacts the upper end surface of the T-plate, so that the connecting rod 132 is blocked by the upper end surface of the T-plate and penetrates into the connecting groove 133, so that the air in the connecting groove 133 is squeezed and pushed by the connecting rod 132 and enters the positioning groove 134 connected to the connecting groove 133, so that the air entering the positioning groove 134 can push the positioning rod 135 out of the positioning groove 134. Since the positioning rod 135 is in contact with the protruding parts on both sides of the upper end of the T-bar at this time, the positioning rod 135 is blocked by the side wall of the T-bar and cannot be extended out of the positioning groove 134, so that the hydraulic As the cylinder 131 pushes the positioning rod 135 downward, the positioning rod 135 slides into contact with the protruding portion of the side wall of the T-shaped plate. During this process, the air in the positioning groove 134 is always in a compressed state until the connecting rod 132 completely enters the connecting groove 133, allowing the positioning rod 135 to pass over the protruding portions on both sides of the T-shaped rod. At this time, the positioning rod 135 is pushed out of the positioning groove 134 by the compressed air in the positioning groove 134, that is, the compressed air pushes the positioning rod 135 to stretch the positioning spring 136 to extend out of the positioning groove 134, so that the positioning rod 135 cooperates with the hydraulic cylinder 131 to clamp the protruding portion of the upper end of the T-shaped plate.

[0039] Subsequently, the driving motor 111 is controlled to drive the turntable 11 to rotate, so that the turntable 11 drives the pressing mold 12 to rotate toward the conveying device on the right side of the turntable 11. After the turntable 11 drives the pressing mold 12 to rotate 90 degrees, the staff first controls the hydraulic cylinder 131 to extend, so that the hydraulic cylinder 131 pulls the upper mold 121 T-plate clamped by it through the positioning rod 135 to drive the upper mold 121 to rise, so that the upper mold 121 and the lower mold 122 of the pressing mold 12 are separated, that is, the lower mold 122 is in an open state at this time, and then the staff uses the feeding equipment to guide the glass drop to the lower mold 122 of the pressing mold 12 2, and then control the hydraulic cylinder 131 to extend and retract, so that the hydraulic cylinder 131 can push the upper mold 121 down, so that the upper mold 121 is inserted into the lower mold 122. At this time, the glass drop in the lower mold 122 flows in the pressing mold 12 and fills the mold cavity to form a shape consistent with the mold cavity. Then, continue to control the drive motor 111 to drive the turntable 11 to rotate, so that the turntable 11 drives the pressing mold 12 of the molded glass to rotate to the conveying device on the right side of the turntable 11. At this time, the user controls the electromagnetic valve 138 in the air hole 137 to open, so that the positioning groove 134 is connected to the air hole 137, so that the positioning groove 134 is connected to the air hole 137. The compressed air in the 34 can be discharged from the air hole 137, so that the positioning rod 135 in the positioning groove 134 enters the positioning groove 134 under the pull of the positioning spring 136. At this time, the positioning rod 135 no longer supports and clamps the T-plate. Therefore, the user only needs to control the hydraulic cylinder 131 to shrink, so that the hydraulic cylinder 131 can pull the positioning rod 135 and the connecting rod 132 to rise, so that the positioning rod 135 passes over the two sides of the T-plate of the upper mold 121, and the connecting rod 132 extends out of the connecting groove 133 again under the action of gravity until the hydraulic cylinder 131 is completely retracted. At this time, the hydraulic cylinder 131 and the upper mold 121 are in a state of tension. 1 is separated. Similarly, the hydraulic push rod 113 contracts, causing the hydraulic push rod 113 to pull the heating box 112 down. At this time, the heating box 112 drives the pressing mold 12 to descend until the pressing mold 12 contacts the guide rod 14. Supported by the guide rod 14, the pressing mold 12 extends from the descending heating box 112, separating the heating box 112 from the pressing mold 12. Subsequently, the user only needs to use a tool such as a hook to pull the pressing mold 12 on the guide rod 14 to the conveying device on the right, so that the conveying device can convey the molded glass pressing mold 12 to the cooling zone for solidification and cooling of the glass product.

[0040] During the process of the hydraulic cylinder 131 pushing the upper mold 121 and the lower mold 122 for molding, a clamping rod is fixedly connected to the lower end of the upper mold 121, and a clamping groove is opened at the upper end of the lower mold 122. During the process of clamping the upper mold 121 and the lower mold 122, the clamping rod at the lower end of the upper mold 121 is inserted into the clamping groove at the upper end of the lower mold 122. Since the glass drop inside the lower mold 122 is in a high-temperature molten state, it will radiate heat outward. Under the influence of this heat radiation, the clamping rod located in the clamping groove will undergo physical expansion. As the mold clamping rod expands due to heat, its size gradually increases and eventually it is tightly engaged in the mold clamping groove. Therefore, after the hydraulic cylinder 131 is separated from the upper mold 121, the upper mold 121 and the lower mold 122 still maintain a tightly clamped state. Then, when the conveying device can convey the molded glass pressing mold 12 to the cooling zone for solidification and cooling of the glass product, the glass product in the lower mold 122 can still be subjected to stable pressure and slowly cooled, thereby effectively improving the molding quality of the glass product.

[0041] The reason why the inner wall of the heating box 112 is coated with graphite is that graphite material is a material with good heat resistance and low thermal conductivity, which can prevent heat conduction. This allows the heating box 112 to heat the lower mold 122. The temperature inside the heating box 112 can be concentrated inside the heating box 112 under the barrier of the graphite coating, reducing the heat loss to the outside through the inner wall of the heating box 112. This means that when the heating box 112 heats and softens the glass in the lower mold 122, the additional heat input required to maintain the appropriate temperature of the lower mold 122 is reduced. Subsequently, in actual production, energy consumption can be reduced, thereby achieving the purpose of energy saving. This energy saving The effect not only helps to reduce production costs, but also conforms to the concept of sustainable development, bringing a double improvement in economic and environmental benefits to the enterprise. Similarly, a graphite coating is coated on the lower end surface of the upper mold 121, which can enable the graphite coating to block the heat in the lower mold 122 from diffusing outward through the upper mold 121, thereby reducing heat loss and reducing energy consumption. In addition, the graphite coating on the lower end surface of the upper mold 121 blocks the heat diffusion in the lower mold 122, which can reduce the heat transfer to the hydraulic cylinder 131, so as to reduce the heat at the solenoid valve 138, thereby ensuring the stability of the working environment temperature of the solenoid valve 138, so that the use effect and service life of the solenoid valve 138 are improved.

[0042] Since the sizes of different types of glass are different, the sizes of the pressing molds 12 used are also different. In order to ensure that the guide rods 14 can effectively support and guide pressing molds 12 of different sizes, the present invention sets a screw 143. When it is necessary to adjust the distance between the guide rods 14, that is, when it is necessary to support a small pressing mold 12, the user only needs to control the electromagnetic plate 154 to energize so that the electromagnetic plate 154 can generate a magnetic adsorption force on the bevel gear shaft 151, so that the bevel gear shaft 151 is adsorbed by the electromagnetic plate 154 and squeezes the transmission spring 153 into the rectangular groove 152, so that the bevel gear shaft 151 is separated from the bevel gear ring 142. Since the bevel gear shaft 151 is connected to the bevel gear shaft 155, the bevel gear shaft 151 can drive the bevel gear shaft 155 to approach the bevel gear ring 144 until the bevel gear shaft 155 contacts and meshes with the bevel gear ring 144. At this time, the servo motor 15 is controlled to rotate so that the servo motor 15 can drive the bevel gear ring 144 to rotate through the bevel gear shaft 155, so that the bevel gear ring 144 can drive the screw 143 fixed to it to rotate, so that the rotating screw 143 can drive the two adjacent guide rods 14 to move in a direction close to each other, so that the guide rods 14 can effectively support the small pressing mold 12, thereby expanding the practical application range of the present invention and further improving the practicality of the present invention. The setting of the threaded groove 114 and the threaded rod 115 is to facilitate the replacement of heating boxes 112 of different sizes, so that heating boxes 112 of different sizes can match pressing molds 12 of different sizes, thereby improving the heating effect of the heating box 112 on the pressing mold 12, so as to ensure that the glass drop in the pressing mold 12 can be in a softened state during the pressing process, thereby improving the molding effect of the present invention on the glass drop; thereby further improving the practicality of the present invention.

[0043] As an embodiment of the present invention, the lower end of the turntable 11 is slidably connected to a support rod 16; a slot 145 is provided on one side of the guide rod 14 to cooperate with the support rod 16; a magnetic block 161 is embedded in the end of the support rod 16 away from the guide rod 14; and an electromagnetic sheet 162 is embedded in the lower end of the turntable 11 to face the magnetic block 161.

[0044] As an embodiment of the present invention, a caster 17 is provided above the guide rod 14 ; the caster 17 is slidably connected to the guide rod 14 via a Y-shaped rod 171 ; a tightening rod 172 is spirally connected to one side of the Y-shaped rod 171 .

[0045] As an embodiment of the present invention, one end of the pressing rod 172 close to the guide rod 14 is rotatably connected to a pressing block 173 ; the pressing block 173 is made of fluororubber material.

[0046] During operation, the large pressing mold 12 has a relatively large volume, so its weight is also relatively large. At this time, in order to improve the supporting effect of the guide rod 14 on the large pressing mold 12, the present invention provides a support rod 16. When the guide rod 14 rotates to a horizontal position, the slot 145 on one side of the guide rod 14 is opposite to the support rod 16. At this time, the electromagnetic sheet 162 is energized so that the electromagnetic sheet 162 generates the same magnetic force as the magnetic block 161. Due to the principle of like charges repel, the magnetic block 161 moves away from the electromagnetic sheet 162 under the push of the magnetic repulsion, so that the magnetic block 161 pushes the support rod 16 fixed thereto close to the slot 145 on one side of the guide rod 14 until the support rod 16 is inserted into the slot 145. At this time, the support rod 16 is blocked by the inner wall of the slot 145 and stops, and then the electromagnetic plate 162 is controlled to be de-energized, so that the guide rod 14 is fixedly connected to the turntable 11 under the insertion of the support rod 16, so that the support rod 16 can increase the support points below the guide rod 14. By increasing the support points, the pressure applied by the pressing mold 12 to the guide rod 14 can be dispersed, and the pressure of the pressing mold 12 is avoided from being concentrated on the end of the guide rod 14 away from the rotating rod 141, preventing the guide rod 14 from bending due to excessive local force, increasing the support points, and distributing the pressure to each support point, so that the internal stress distribution of the guide rod 14 is more uniform, reducing stress concentration, and reducing the problem of bending and deformation of the guide rod 14, thereby improving the actual application effect of the guide rod 14.

[0047] By setting the casters 17, on the one hand, the surface contact between the pressing mold 12 and the guide rod 14 is changed to point contact, so that the friction between the pressing mold 12 and the guide rod 14 is reduced, so that the pressing mold 12 can slide quickly along the guide rod 14 to contact with the turntable 11 under the action of the casters 17, thereby improving the working efficiency of the present invention. On the other hand, during long-term use, the weakening of the friction effect between the pressing mold 12 and the guide rod 14 can reduce the friction loss between the pressing mold 12 and the guide rod 14, thereby improving the service life and use effect of the pressing mold 12 and the guide rod 14.

[0048] The setting of the clamping rod 172 is that when the guide rod 14 guides and supports the pressing molds 12 of different sizes, the user can selectively increase or decrease the number of casters 17. For example, increasing the number of casters 17 is to enable the small pressing mold 12 to slide stably on a larger number of casters 17, so that a larger number of casters 17 can effectively support the pressing mold 12. The gap between two adjacent casters 17 is larger, causing the small pressing mold 12 to fall between the two casters 17. For larger pressing molds 12, the number of casters 17 is reduced, thereby effectively reducing the contact area between the casters 17 and the pressing mold 12, that is, reducing friction and reducing kinetic energy loss, thereby allowing the large pressing mold 12 to quickly slide along the guide rod 14 until it contacts the turntable 11, thereby improving the working efficiency of the present invention. For the connection between the caster 17 and the guide rod 14, the Y-shaped rod 171 of the caster 17 can be inserted into the upper end of the guide rod 14, and the Y-shaped rod 171 is slid so that the Y-shaped rod 17 The cam 173 is pressed against the guide rod 14 so that the cam 173 can be adjusted relative to the guide rod 14.
