Description

Technical Field

[0001] The invention relates to the technical field of glass production, and in particular to a special glass uniform distribution molding system based on a centrifugal mold. Background Art

[0002] Special glass is a high-performance glass material made by adjusting the composition of traditional glass or using special processes. It has physical properties, optical properties and chemical stability that traditional glass does not have. The application of centrifugal molds in glass manufacturing is to generate centrifugal force by rotating the mold at high speed, so that the molten glass is evenly distributed on the mold surface, and after cooling, a uniformly formed glass product is obtained.

[0003] In this regard, the present application designs a special glass uniform distribution molding system based on a centrifugal mold. Existing glass centrifuges are mainly used for ordinary glass products, and most of them use non-closed molds and open production environments. Since special glass has high requirements for temperature control, the heat dissipates quickly after the centrifugal mold is heated, and the temperature changes too quickly during the cooling process, which will cause internal stress, resulting in uneven heating of the molten glass and defects such as cracks; and the viscosity of special glass in a molten state is significantly higher than that of ordinary glass, so the rotation speed needs to be increased to enhance the centrifugal force to evenly fill the mold. During this period, when the molten glass is exposed to the air and centrifuged, the high-speed rotation can expel the bubbles in the molten glass, but it will also cause surface disturbances and wrap a small amount of air to form micron-sized bubbles; in addition, during the high-speed centrifugation process of the open centrifugal mold, it is easy for the molten glass to leak and cause fire or equipment damage.

[0024] The upper and lower ends of the ball screw 42 are optical axis sections, and the middle part is a spiral section. An auxiliary tray 45 is movably mounted on the outer wall of the optical axis section of the ball screw 42 on the upper side of the turntable 41. The upper end of the auxiliary tray 45 is movably fitted on the lower end surface of the mold tray 2 53, and a compression spring is mounted on the outer wall of the ball screw 42 between the turntable 41 and the auxiliary tray 45.

[0025] The driving component 44 includes a forward and reverse motor 441 installed through a motor seat in the middle of the chassis 1. The output shaft of the forward and reverse motor 441 rotates through the chassis 1 and is fixedly connected to the turntable 41. A support shaft rotatably connected to the turntable 41 is installed on the inner wall of the upper end of the outer tube of the telescopic tube 3. The outer wall of the support shaft rotates and fits on the inner wall of the ball screw 42. The outer walls on both sides of the outer tube of the telescopic tube 3 are fixedly connected to the chassis 1 through connecting plates.

[0026] The driving member 44 also includes a servo motor 442 installed through a motor seat on the right side of the forward and reverse motor 441 in the chassis 1. The output shaft of the servo motor 442 rotates and passes through the chassis 1, and is fixedly connected to a transmission gear 443. The inner gear ring and the outer gear ring are rotatably installed at the position corresponding to the transmission gear 443 on the upper end of the chassis 1. The outer gear ring is fixedly sleeved on the outer wall of the inner gear ring, and the transmission gear 443 is meshed with the inner gear ring. The lower ends of multiple stepped support columns 51 are fixedly sleeved with passive gears 444, and the multiple passive gears 444 are meshed with the outer gear ring.

[0027] The lower end of the outer tube of the telescopic tube 3 is provided with a plurality of avoidance holes evenly distributed in a circle, and the positions of the avoidance holes on the left and right connecting plates on the outer wall of the telescopic tube 3 are also provided with avoidance holes, and the positions on the outer wall of the inner tube of the telescopic tube 3 corresponding to the plurality of avoidance holes are penetrated and installed with automatic flamethrowers 6.

[0028] When implementing: The inner cylinder of the telescopic cylinder 3 in the present application is initially retracted to the upper side to be in an open state. At this time, multiple automatic flamethrowers 6 are also located at the upper side position, and the mold tray 2 53 together with multiple upper molds 55 are all located at the upper side position. When the glass melt is fed, the turntable 41 is first controlled by the forward and reverse motor 441 to drive the mold tray 2 to rotate intermittently in the forward direction, and the mold tray 2 drives the multiple lower molds 52 to rotate intermittently. It should be noted that since the screw nut 43 is also located on the upper side and is in a state of being separated from the ball screw 42, when the turntable 41 drives the ball screw 42 to rotate forward, it will not restore the spiral connection with the screw nut 43 to drive the screw nut 43 to move, and at this time, the balls in the screw nut 43 will not be scattered under the blocking effect of the outer wall of the optical axis section at the upper end of the ball screw 42, so that the spiral connection with the ball screw 42 can be restored later, and then the external glass melt automatic feeding device will quantitatively deliver the glass melt to the multiple lower molds 52 in sequence.

[0029] When the molten glass is heated, after the feeding of the molten glass is completed in the multiple lower molds 52, the forward and reverse motors 441 are used to control the turntable 41 to rotate in the opposite direction. Under the gravity of the mold tray 2 53 and the multiple upper molds 55, the lead screw nut 43 will resume the spiral connection with the ball screw 42, so as to achieve the effect of controlling the ball screw 42 to drive the mold tray 2 53 to move downward through the lead screw nut 43. At this time, the mold tray 2 53 will drive the inner cylinder of the telescopic cylinder 3 to move downward to a position fitted on the mold tray 1 2, and the multiple upper molds 55 will also move downward with the mold tray 2 53, so that the multiple arc slides 565 Insert it into the corresponding arc-shaped sliding hole to achieve the docking effect of the upper mold 55 and the lower mold 52. During this period, when the screw nut 43 moves downward to the position of the lower optical axis section of the ball screw 42, the auxiliary tray 45 is squeezed to make it move downward synchronously until the screw nut 43 is disengaged from the ball screw 42 again, and as the ball screw 42 continues to rotate in the opposite direction, it will not restore the spiral connection with the screw nut 43 to drive the screw nut 43 to move, and then control multiple automatic flamethrowers 6 to heat the glass melt in the multiple lower molds 52, and keep the temperature of the lower mold 52 and the upper mold 55 at a suitable temperature.

[0030] During centrifugal forming of the molten glass, when the temperature of the molten glass in the multiple lower molds 52 is suitable, the servo motor 442 is used to control the transmission gear 443 to rotate, and the transmission gear 443 is used to drive the internal gear ring and the external gear ring to drive the multiple passive gears 444 to rotate synchronously. The multiple passive gears 444 drive the corresponding lower molds 52 and the upper mold 55 to rotate through the corresponding stepped support column 51. It should be noted that at this time, the multiple lower molds 52 and the upper mold 55 are in a semi-open state. The servo motor 442 is used to control the multiple lower molds 52 and the upper mold 55 to rotate at a relatively low speed. When the molten glass is slowly and evenly distributed under the centrifugal force, and the gas in the molten glass is discharged, the servo motor 442 is used to control the multiple lower molds 52 and the upper mold 55 to rotate at a high speed to achieve the centrifugal force required for the molding of the special molten glass. During this period, as the centrifugal force generated by the rotation of the multiple lower molds 52 and the upper mold 55 increases from small to large, the multiple counterweight plates 573 will gradually move toward the circular support column 5 4, and under the cooperation of the installation through hole, the corresponding upper mold 55 is driven to move downward, and the corresponding annular contact plate 564 is pressed together by the multiple arc-shaped slide plates 565 to make it return to the corresponding receiving slide groove. When the centrifugal force required for the special glass melt is reached, the multiple counterweight plates 573 will also extend to the maximum distance. At this time, the corresponding upper mold 55 will be tightly fitted with the corresponding lower mold 52 for sealing until the glass melt is gradually formed. After the glass melt is gradually formed, the multiple automatic flame spray guns 6 can be controlled to stop working and wait for the molded glass product to be initially cooled down, and then the servo motor 442 is used to control the multiple lower molds 52 and the upper mold 55 to gradually reduce the speed and then stop working. It should be noted that when the servo motor 442 controls the multiple lower molds 52 and the upper mold 55 to gradually reduce the speed, under the action of the compression spring, the multiple counterweight plates 573 will return to the corresponding limit slide groove, and the circular support column 54 will drive the upper mold 55 to move upward to restore to its original position.

[0031] When taking out the formed glass products, it is necessary to control the turntable 41 to rotate forwardly again through the forward and reverse motor 441. Under the action of the compression spring, the auxiliary tray 45 will push the screw nut 43 upward, and the auxiliary screw nut 43 and the ball screw 42 will resume the spiral connection, thereby achieving the effect of controlling the ball screw 42 to drive the mold tray 2 53 to move upward through the screw nut 43. At this time, the multiple upper molds 55 will also follow the upward movement and return to their original positions, so that the lower mold 52 is in an open state for cooling and material removal. Then, the turntable 41 is controlled by the forward and reverse motor 441 to drive the mold tray 2 from forward continuous rotation to forward intermittent rotation. The multiple lower molds 52 will drive the corresponding formed glass products to rotate forward intermittently, and then the external cooling equipment will perform secondary cooling on the multiple formed glass products in turn. After they are cooled to room temperature, the external automatic material removal equipment can take out the multiple formed glass products in turn.

[0032] When installing the lower mold 52 and the upper mold 55, the staff will rotate the corresponding annular rotating plate 562 by 45 degrees, so that the arc magnet 563 on the annular rotating plate 562 is respectively released from the magnetic connection with the arc magnet 563 on the corresponding stepped support column 51 or the circular support column 54. Under the action of the compression spring, the multiple plug-in rods 561 will slide toward the inner wall direction of the corresponding annular rotating plate 562, and then the staff will insert the installation rods 56 on the lower mold 52 or the upper mold 55 into the corresponding installation grooves, and control the multiple plug-in rods 561 to slide along the guide grooves on the outer walls of the installation rods 56 until the insertion end of the installation rod 56 on the lower mold 52 or the upper mold 55 is tightly fitted with the corresponding installation rods. On the inner wall of the groove, the staff will finally rotate the corresponding annular rotating plate 562 by 45 degrees again, so that the arc magnet 563 on the annular rotating plate 562 can restore the magnetic connection with the corresponding arc magnet 563 on the stepped support column 51 or the circular support column 54, and multiple plug-in rods 561 will be inserted into the corresponding circular slots respectively, so as to achieve the effect of quick plug-in of the lower mold 52 and the upper mold 55. When disassembling, the staff will rotate the corresponding annular rotating plate 562 by 45 degrees, so that the arc magnet 563 on the annular rotating plate 562 can release the magnetic connection with the corresponding arc magnet 563 on the stepped support column 51 or the circular support column 54, and the lower mold 52 and the upper mold 55 can be directly pulled out.

[0033] In summary, this application has the following advantages: Advantage 1: When the molten glass is heated, the forward and reverse rotation of the turntable 41 is controlled by the forward and reverse motor 441, so that the screw nut 43 and the ball screw 42 can be controlled to disengage or restore the spiral connection. During this period, whenever the screw nut 43 moves to the position of the upper or lower optical axis section of the ball screw 42, the screw nut 43 will be disengaged from the spiral connection with the ball screw 42, and as the ball screw 42 continues to rotate forward or reverse, it will not restore the spiral connection with the screw nut 43 to drive the screw nut 43 to move, thereby realizing the free control of the inner cylinder of the telescopic cylinder 3 to rise or fall, and continuing to control the mold tray 2 to drive the multiple lower molds 52 to rotate forward or reverse intermittently.

[0034] Advantage 2: At the same time, multiple upper molds 55 can be controlled to rise or fall with the mold tray 2 53, so that multiple arc-shaped slides 565 are inserted into corresponding arc-shaped sliding holes, thereby achieving the effect of controlling the upper mold 55 and the lower mold 52 to dock or disengage, and then controlling multiple automatic flamethrowers 6 to heat the molten glass in the multiple lower molds 52, and in the closed environment of the telescopic cylinder 3, the temperature of the lower mold 52 and the upper mold 55 is maintained at a suitable temperature to avoid the centrifugal mold from dissipating heat quickly after being heated, resulting in uneven heating of the molten glass and defects such as cracks.

[0035] Advantage three, when the glass solution is heated, the turntable 41 is controlled by the forward and reverse motor 441 to drive the mold tray 2 53 to rotate in the opposite direction. Under the transmission action of multiple passive gears 444 and the outer gear ring, the multiple lower molds 52 and the upper mold 55 will slowly rotate while rotating around the turntable 41, thereby achieving the effect of improving the uniformity of heating when the subsequent multiple automatic flamethrowers 6 heat the multiple lower molds 52, the upper mold 55 and the glass melt.

[0036] Advantage 4: When the glass melt is centrifugally formed, the servo motor 442 is used to control the multiple lower molds 52 and the upper mold 55 to rotate at a relatively low speed. When the glass melt is slowly and evenly distributed under the centrifugal force and the gas in the glass melt is discharged, the servo motor 442 is used to control the multiple lower molds 52 and the upper mold 55 to rotate at a relatively high speed to achieve the centrifugal force required for the special glass melt to be formed. During this period, as the centrifugal force generated by the rotation of the multiple lower molds 52 and the upper mold 55 increases from small to large, the multiple counterweight plates 573 will gradually extend outward from the circular support column 54, and under the cooperation of the installation through hole, jointly drive the corresponding upper mold 5 5 moves downward, and the corresponding annular abutment plate 564 is pressed together by the multiple arc-shaped slide plates 565 to make it return to the corresponding receiving slide groove. When the centrifugal force required for the special glass melt is reached, the multiple counterweight plates 573 will also extend to the maximum distance. At this time, the corresponding upper mold 55 will gradually change from a semi-open state to a tightly fitted sealing state with the corresponding lower mold 52, so as to avoid the problem that when the glass melt is exposed to the air and centrifuged at a high speed to uniformly fill the mold, the rotation may cause the surface to be wrapped with air to form bubbles, and the leakage of the glass melt can be avoided to cause fire or equipment damage.

[0037] Advantage five, when taking out the formed glass products, first control the formed glass products to be initially cooled down in the closed environment of the telescopic cylinder 3, and then control the ball screw 42 through the forward and reverse motor 441 to drive the mold tray 2 53 to move upward through the screw nut 43. At this time, the inner cylinder of the telescopic cylinder 3 and multiple upper molds 55 will also move upward and return to their original positions, so that the lower mold 52 is in an open state for secondary cooling and material removal. At the same time, it avoids the problem of internal stress caused by excessive temperature changes in the cooling process of the lower mold 52 and the upper mold 55, which affects the quality of the glass products.

[0038] Advantage 6: When installing the lower mold 52 and the upper mold 55, the corresponding annular rotating plate 562 is rotated 45 degrees to release the magnetic connection between the arc magnet 563 on the annular rotating plate 562 and the corresponding stepped support column 51 or the arc magnet 563 on the circular support column 54, and the mounting rod 56 on the lower mold 52 or the upper mold 55 is respectively inserted into the corresponding mounting groove, and the corresponding annular rotating plate 562 is rotated 45 degrees again to release the magnetic connection between the arc magnet 563 on the annular rotating plate 562 and the corresponding stepped support column 51 or the circular support column 54. The arc-shaped magnet 563 on the stepped support column 51 or the circular support column 54 restores the magnetic connection, and the multiple plug-in rods 561 are respectively inserted into the corresponding circular slots. When disassembling, the corresponding annular rotating plate 562 is rotated 45 degrees to release the magnetic connection between the arc-shaped magnet 563 on the annular rotating plate 562 and the corresponding arc-shaped magnet 563 on the stepped support column 51 or the circular support column 54, and the lower mold 52 and the upper mold 55 can be directly pulled out, thereby achieving the effect of quick loading and unloading of the lower mold 52 and the upper mold 55.
