[0002] The forming of glass is the process of converting molten glass into a geometric product, which is called primary forming or hot end forming of glass. Glass must be formed within a certain viscosity (temperature) range.

[0003] The existing glass lampshade blow forming die when using, when the spring in it is used for a long time, fatigue phenomenon occurs, leading to poor elasticity, loss of elasticity, deformation and the like, and the existing glass lampshade blow forming die is not convenient for replacing spring, and when two half-molds contact, it cannot be fixed, and staff need to be pressed on pressing plate all the time, which has certain defects in use. In view of this, a kind of blow molding glass forming die is provided. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a kind of blow molding glass forming die to solve the problems raised in the above background.

[0005] Therefore, the utility model provides a kind of blow molding glass forming die, comprising:

[0006] Base, two vertical plates are fixedly installed on the base, a guide rod and a bidirectional screw rod are rotatably installed between the two vertical plates, two half-molds are arranged between the guide rod and the bidirectional screw rod, one side of the two half-molds is threadedly connected with the bidirectional screw rod, and the other side of the two half-molds is slidably connected with the guide rod.

[0007] Rectangular plate, the rectangular plate is fixedly installed on the top of base, a through slot is formed in the rectangular plate, two sliding plates are slidably installed in the through slot, two round rods are fixedly installed in the through slot, one end of the round rod penetrates through the two sliding plates, a spring is sleeved on the round rod, and the two ends of the spring are tightly welded with the two sliding plates, respectively, a sliding block is arranged on the top of one of the sliding plates and located in the through slot, the top end of the two round rods penetrates through the sliding block, and a rack is fixedly installed on one side of the sliding block.

[0008] Rotary plate, the rotary plate is rotatably installed on the top of rectangular plate, a connecting plate is rotatably installed on one end of the rotary plate, and the connecting plate is fixed with the rectangular plate by two fixing screws.

[0009] Transmission assembly, the transmission assembly is located on the base and is used for transmission.

[0010] A limiting component is located on the base and is used to limit the slider.

[0011] In this technical solution, the device is installed below the workbench. The user stands on the workbench and places the glass lampshade to be blown on the center seat. Then, the rack moves downward, causing the slider to slide downward on the two round rods. One of the sliding plates also moves downward on the two round rods. The springs fitted on the round rods are compressed and contract. At the same time, the rack drives the bidirectional threaded rod to rotate forward through the transmission component. Under the action of the thread, the bidirectional threaded rod will drive the two half molds to move closer to each other. The two half molds will slide on the guide rod and move closer to each other until the two half molds contact each other. At this time, the limiting component will limit the position of the slider, eliminating the need for the operator to keep stepping on the pressing rod with their foot.

[0012] Then, air is blown through a blowpipe to expand the glass lampshade and make it fit against the inner wall of the semi-mold. After the glass lampshade cools and sets, the limiting component is used to release the limiting component from the slider. Then, under the action of the rebound force of the two springs, the two springs will push one of the sliding plates downward, causing the slider to move upward. The slider will drive the rack to move upward, and the transmission component will drive the bidirectional threaded rod to rotate in the opposite direction, so that the two semi-molds move away from each other and open, and then the glass lampshade can be taken out.

[0013] When the spring needs to be replaced, the worker uses a screwdriver to remove the two fixing screws, thus releasing the connecting plate. The connecting plate can then be rotated, causing it to rotate and open. The worker can then remove the slider from the two rods. One of the sliders is then moved upwards, causing the two springs to move upwards. These two springs, in turn, cause the other slider to move upwards on the two rods until it is completely removed from the rods. Then, a new spring can be installed.

[0014] In the above technical solution, the transmission component further includes:

[0015] A fixed plate is fixedly installed on one side of a rectangular plate. Two transmission wheels are rotatably installed on one side of the fixed plate, and a belt is installed between the two transmission wheels. A gear is rotatably installed on the other side of the fixed plate. The gear meshes with a rack. One end of the gear passes through the fixed plate and is coaxially connected to one of the transmission wheels. One end of the other transmission wheel passes through the fixed plate and one of the vertical plates and is coaxially connected to a bidirectional threaded rod.

[0016] In this technical solution, the operator can step down on the pressure lever, which will cause the rack to move downwards. Under the meshing action, the rack will drive the gear to rotate forward, which will drive one of the transmission wheels to rotate. This transmission wheel will drive the belt drive, which will drive the other transmission wheel to rotate. Subsequently, the other transmission wheel will drive the double-ended threaded rod to rotate.

[0017] In the above technical solution, furthermore, one end of the other drive wheel is rotatably connected to one of the upright plates.

[0018] In this technical solution, it is ensured that one end of the other drive wheel can rotate within one of the vertical plates.

[0019] In the above technical solution, the limiting component further includes:

[0020] A side plate is fixedly installed on the top of the base and located on the other side of the rectangular plate. A cavity is opened on one side of the side plate. A groove is opened in the side plate at the top and bottom of the cavity. A limit block is slidably installed in the cavity. Several rollers that contact the limit block are rotatably installed in the groove. A magnet is fixedly installed at one end of the limit block. A pull rod is fixedly installed at the other end of the limit block. One end of the pull rod passes through one side of the cavity and extends to the outside.

[0021] The second groove is located on the other side of the slider, and a magnet is fixedly installed inside the second groove.

[0022] In this technical solution, when the second groove is connected to the cavity, under the action of magnetic attraction, the second magnet will move toward the first magnet, causing the limiting block to move within the cavity. At this time, several rollers at the top and bottom of the limiting block will rotate to ensure smoother movement of the limiting block. Subsequently, one end of the limiting block will enter the second groove, and the second magnet will contact and magnetically connect with the first magnet, thereby limiting the position of the slider without requiring the operator to continuously step on the pressure rod.

[0023] In the above technical solution, the cross-sectional dimensions of the second groove are adapted to the cross-sectional dimensions of the limiting block, the second magnet is magnetically connected to the first magnet, and one end of the limiting block is slidably connected to the second groove.

[0024] In this technical solution, it is ensured that one end of the limiting block can enter the second groove, that the second magnet and the first magnet can be magnetically connected, and that one end of the limiting block can slide within the second groove.

[0025] In the above technical solution, a central seat is fixedly installed on the top of the base and between the two half molds, the slider is slidably connected to the round rod, and the sliding plate is slidably connected to the round rod.

[0026] In this technical solution, it is ensured that the glass lampshade to be blown can be placed on the central seat, which facilitates the subsequent blow molding process, and that the slider and the sliding plate can slide on the round rod.

[0027] In the above technical solution, a pressing rod is further fixedly installed at the top of the rack, and the spring is located between the two sliding plates.

[0028] In this technical solution, it is ensured that the rack can be driven to move downward by the stepping rod, so that the two ends of the spring can be fixed to the two sliding plates respectively.

[0029] The beneficial effects of this utility model are:

[0030] This blown glass forming mold, through the cooperation of rectangular plates, through slots, round rods, sliding plates, springs, rotating plates, connecting plates, fixing screws, and limiting components, ensures that damaged springs can be replaced after long-term use, preventing damaged springs from affecting the operation of the overall device. At the same time, when the two half molds are in contact, the position of the slider can be fixed, eliminating the need for the operator to constantly step on the pressing rod, making it more convenient to use.

[0049] Example 1:

[0050] Please see Figure 1 - Figure 11 As shown, this embodiment provides a blown glass forming mold, including:

[0051] The base 1 has two upright plates 2 fixedly installed on it. A guide rod 4 and a bidirectional threaded rod 5 are rotatably installed between the two upright plates 2. Two half molds 3 are provided between the guide rod 4 and the bidirectional threaded rod 5. One side of the two half molds 3 is threadedly connected to the bidirectional threaded rod 5, and the other side of the two half molds 3 is slidably connected to the guide rod 4.

[0052] A rectangular plate 8 is fixedly installed on the top of the base 1. A through groove 25 is provided in the rectangular plate 8. Two sliding plates 22 are slidably installed in the through groove 25. Two round rods 23 are fixedly installed in the through groove 25. One end of the round rod 23 passes through the two sliding plates 22. A spring 24 is sleeved on the round rod 23. The two ends of the spring 24 are respectively tightly welded to the two sliding plates 22. A slider 18 is provided on the top of one of the sliding plates 22 and located in the through groove 25. The top ends of the two round rods 23 pass through the slider 18. A rack 10 is fixedly installed on one side of the slider 18.

[0053] A rotating plate 12 is rotatably mounted on the top of a rectangular plate 8. A connecting plate 13 is rotatably mounted on one end of the rotating plate 12. The connecting plate 13 is fixed to the rectangular plate 8 by two fixing screws 17.

[0054] A transmission assembly, located on base 1, is used for transmission;

[0055] A limiting component is located on the base 1 and is used to limit the slider 18.

[0056] In use, the device is installed below the workbench. The user stands on the workbench and places the glass lampshade to be blown on the center seat 16. Then, the rack 10 is moved downward, which will cause the slider 18 to slide downward on the two round rods 23. One of the sliding plates 22 will also move downward on the two round rods 23. The spring 24 sleeved on the round rod 23 will be compressed and contract. At the same time, the rack 10 will drive the bidirectional threaded rod 5 to rotate forward through the transmission component. Under the action of the thread, the bidirectional threaded rod 5 will drive the two half molds 3 to move closer to each other. The two half molds 3 will slide on the guide rod 4 and move closer to each other until the two half molds 3 contact each other. At this time, the limiting component will limit the position of the slider 18, so that the operator does not need to step on the foot pressing rod 11.

[0057] Then, air is blown through a blowpipe to expand the glass lampshade and make it fit against the inner wall of the semi-mold 3. After the glass lampshade cools and sets, the limiting component is used to release the limiting component from the slider 18. Then, under the action of the rebound force of the two springs 24, the two springs 24 will push one of the sliding plates 22 downward, causing the slider 18 to move upward. The slider 18 will drive the rack 10 to move upward, and the transmission component will drive the bidirectional threaded rod 5 to rotate in the opposite direction, so that the two semi-molds 3 move away from each other and open, and then the glass lampshade can be taken out.

[0058] When spring 24 needs to be replaced, the worker uses a screwdriver to remove the two fixing screws 17, which will release the connecting plate 13. Then, the connecting plate 13 can be rotated, causing the rotating plate 12 to rotate and open. The worker can then remove the slider 18 from the two round rods 23. Then, one of the sliding plates 22 is moved upward. One of the sliding plates 22 will move the two springs 24 upward, and the two springs 24 will move the other sliding plate 22 upward on the two round rods 23 until the other sliding plate 22 is completely removed from the two round rods 23. Then, a new spring 24 can be replaced.

[0059] Example 2:

[0060] This embodiment provides a blown glass forming mold, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a transmission component:

[0061] A fixed plate 6 is fixedly installed on one side of a rectangular plate 8. Two transmission wheels 14 are rotatably installed on one side of the fixed plate 6, and a belt 15 is installed between the two transmission wheels 14. A gear 7 is rotatably installed on the other side of the fixed plate 6. The gear 7 meshes with a rack 10. One end of the gear 7 passes through the fixed plate 6 and is coaxially connected to one of the transmission wheels 14. One end of the other transmission wheel 14 passes through the fixed plate 6 and one of the vertical plates 2 and is coaxially connected to a bidirectional threaded rod 5.

[0062] The operator can step on the pressure bar 11, which will cause the rack 10 to move downward. Under the action of meshing, the rack 10 will drive the gear 7 to rotate in the forward direction. The gear 7 will drive one of the transmission wheels 14 to rotate. One of the transmission wheels 14 will drive the belt 15 to drive the belt 15 to rotate. The belt 15 will drive the other transmission wheel 14 to rotate. Subsequently, the other transmission wheel 14 will drive the bidirectional threaded rod 5 to rotate.

[0063] Example 3:

[0065] This ensures that one end of the other drive wheel 14 can rotate within one of the vertical plates 2.

[0066] Example 4:

[0067] This embodiment provides a blown glass forming mold, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a limiting component:

[0068] Side plate 9 is fixedly installed on the top of base 1 and located on the other side of rectangular plate 8. A cavity 27 is opened on one side of side plate 9. Grooves 26 are opened in the top and bottom of cavity 27. Limiting blocks 21 are slidably installed in cavity 27. Several rollers 19 that contact the limiting blocks 21 are rotatably installed in groove 26. A magnet 30 is fixedly installed at one end of limiting block 21. A pull rod 20 is fixedly installed at the other end of limiting block 21. One end of pull rod 20 passes through one side of cavity 27 and extends to the outside.

[0069] Groove 29 is located on the other side of slider 18, and magnet 28 is fixedly installed inside groove 29.

[0070] When the second groove 29 is connected to the cavity 27, under the action of magnetic attraction, the second magnet 30 will move towards the first magnet 28, so that the limiting block 21 moves within the cavity 27. At this time, several rollers 19 at the top and bottom of the limiting block 21 will rotate to ensure that the movement of the limiting block 21 is smoother. Subsequently, one end of the limiting block 21 will enter the second groove 29, and the second magnet 30 will contact the first magnet 28 and be magnetically connected to it, thereby limiting the position of the slider 18 without the need for the operator to keep stepping on the foot pedal 11.

[0071] Example 5:

[0073] Specifically, it ensures that one end of the limiting block 21 can enter the second groove 29, that the second magnet 30 and the first magnet 28 can be magnetically connected, and that one end of the limiting block 21 can slide within the second groove 29.

[0074] Example 6:

[0075] This embodiment provides a blown glass forming mold, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a center seat 16 is fixedly installed on the top of the base 1 and between the two half molds 3; a slider 18 is slidably connected to a round rod 23; and a sliding plate 22 is slidably connected to a round rod 23.

[0076] In particular, it is ensured that the glass lampshade to be blown can be placed on the center seat 16 to facilitate the subsequent blow molding, that the slider 18 can slide on the round rod 23, and that the sliding plate 22 can slide on the round rod 23.

[0077] Example 7:

[0078] This embodiment provides a blown glass forming mold, which, in addition to the technical solution of the above embodiment, also has the following technical features: a pressing rod 11 is fixedly installed at the top of the rack 10, and a spring 24 is located between two sliding plates 22.

[0079] Specifically, it is ensured that the rack 10 can be driven to move downward by the stepping rod 11, so that the two ends of the spring 24 can be fixed to the two sliding plates 22 respectively.

[0080] It is worth noting that the structure and principle of the semi-mold 3 and the center seat 16 in this embodiment are existing technologies. For details, please refer to the prior art document (publication number CN220642896U, patent name is a glass lampshade blowing molding mold), which will not be repeated here.

[0081] Working principle: In use, the device is installed under the workbench. The user stands on the workbench and places the glass lampshade to be blown on the center seat 16. Then, the operator can step down on the pressure rod 11. Stepping on the pressure rod 11 will cause the rack 10 to move downward. The rack 10 will cause the slider 18 to slide downward on the two round rods 23. One of the sliding plates 22 will also move downward on the two round rods 23. The spring 24 sleeved on the round rod 23 will be compressed and contract. At the same time, under the meshing action, the rack 10 will drive the gear 7 to rotate forward. The gear 7 will drive one of the transmission wheels 14 to rotate. One of the transmission wheels 14 will drive the belt 15 to drive the other transmission wheel 14 to rotate. Subsequently, the other transmission wheel 14 will... The double-threaded rod 5 rotates, and under the action of the thread, the double-threaded rod 5 will drive the two half molds 3 to move closer to each other. The two half molds 3 will slide on the guide rod 4 and move closer to each other until the two half molds 3 come into contact. At this time, the groove 29 will be connected to the cavity 27. Under the action of magnetic attraction, the magnet 30 will move towards the magnet 28, so that the limiting block 21 will move in the cavity 27. At this time, several rollers 19 at the top and bottom of the limiting block 21 will rotate to ensure that the movement of the limiting block 21 is smoother. Then, one end of the limiting block 21 will enter the groove 29, and the magnet 30 will contact the magnet 28 and be magnetically connected to it, so that the position of the slider 18 can be limited, without the operator having to step on the foot pedal 11 all the time.

[0082] Then, by blowing air through a blowpipe, the glass lampshade expands and fits against the inner wall of the semi-mold 3. After the glass lampshade cools and sets, the pull rod 20 is pulled by hand, causing the pull rod 20 to move the limiting block 21 away from the slider 18 until one end of the limiting block 21 is completely removed from the groove 29, so that the magnet 30 is no longer magnetically connected to the magnet 28. At this time, the slider 18 will be released from its limit. Subsequently, under the action of the rebound force of the two springs 24, the two springs 24 will push one of the sliding plates 22 downward, causing the slider 18 to move upward. The slider 18 will drive the rack 10 to move upward. Under the action of meshing, the rack 10 will drive the gear 7 to rotate in the opposite direction, so that the two semi-molds 3 can move away from each other and open, and then the glass lampshade can be taken out.

[0083] When spring 24 needs to be replaced, the worker uses a screwdriver to remove the two fixing screws 17, which will release the connecting plate 13. Then, the connecting plate 13 can be rotated, causing the rotating plate 12 to rotate and open. The worker can then remove the slider 18 from the two round rods 23. Then, one of the sliding plates 22 is moved upward. One of the sliding plates 22 will move the two springs 24 upward, and the two springs 24 will move the other sliding plate 22 upward on the two round rods 23 until the other sliding plate 22 is completely removed from the two round rods 23. Then, a new spring 24 can be replaced.

[0084] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
