Description

Technical Field

[0001] The present invention relates to the technical field of glass bottle processing equipment, and particularly to a lightweight glass bottle small-mouth press-blowing device and a process method. Background Art

[0002] The small-mouth press-blowing process is an important link in the production of glass bottles, and is usually used to manufacture glass bottles or containers with a smaller caliber. Generally, the production of glass bottles starts from raw materials. After the raw materials are mixed, they are melted at high temperature to form molten glass. The mixed raw materials are fed into a furnace and melted into liquid glass through high-temperature heating. The melted glass usually remains between 1400 and 1600 degrees Celsius. The molten glass is taken out through a pipe or a mold to form a preliminary blank. The blank is placed in a preheated mold, and then a blowing device is used to blow and press the blank. When the blank enters the preheated mold, there is a process of blank flipping.

[0003] This is an unnecessary action for the forming of glass bottles. Because during the transfer process, the blank will further cool and harden, affecting the subsequent blow forming. And during the flipping process, the outer shape and internal expansion holes of the blank will be bent. If blow pressing is carried out at this time, the thickness of the outer wall of the glass bottle will be uneven. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a lightweight glass bottle small-mouth press-blowing device, which includes a power mechanism. The power mechanism further includes a mounting frame. A top of the mounting frame is fixedly connected with an electric telescopic rod. An end of the electric telescopic rod away from the mounting frame is fixedly connected with a connecting frame. An inner wall of a through hole of the connecting frame is fixedly connected with a pressing rod. A top of the mounting frame is fixedly connected with a fixing plate. A side wall of the fixing plate is fixedly connected with a support rod. An outer wall of the support rod is rotatably connected with a clamping frame;

[0005] A blow-pressing mechanism, the blow-pressing mechanism includes a linkage bracket fixedly connected to a top of the pressing rod. An end of the linkage bracket away from the pressing rod is rotatably connected with an air intake valve. A bottom of the air intake valve is connected with an inner air outlet pipe in a penetrating manner. An outer wall of the inner air outlet pipe is rotatably connected with an outer air outlet pipe;

[0006] A mold mechanism, the mold mechanism includes a housing fixedly connected to an inner wall of the clamping frame. An inner wall of the housing is fixedly connected with a glass bottle mold. A bottom of the pressing rod is slidably connected with a sliding L-shaped rod. An end of the sliding L-shaped rod away from the pressing rod is fixedly connected with a sliding rod.

[0007] Preferably, the power mechanism further includes a first piston plate slidably connected to the inner wall of the first hydraulic tank. A pushing square rod is fixedly connected to the side wall of the first piston plate. The end of the pushing square rod away from the first piston plate is rotatably connected to the outer wall of the clamping frame. The top of the first hydraulic tank is fixedly connected to a second hydraulic tank. A second piston plate is slidably connected to the inner wall of the second hydraulic tank.

[0008] Preferably, the power mechanism further includes a second piston plate slidably connected to the inner wall of the second hydraulic tank. A first telescopic rod is fixedly connected to the top of the second piston plate. The end of the first telescopic rod away from the second piston plate is fixedly connected to the bottom of the connecting frame. A spring is fixedly connected to the bottom of the second piston plate. A flow-through groove is formed in the bottom of the second hydraulic tank. A fixed L-shaped rod is fixedly connected to the side wall of the mounting frame. The end of the fixed L-shaped rod away from the mounting frame is fixedly connected to a limiting plate. After the equipment finishes blow molding, the electric telescopic rod stops operating and waits for the glass bottle inside the glass bottle mold to cool and harden. After the glass bottle is cooled, the electric telescopic rod moves downward, driving the connecting frame to press the first telescopic rod and the second piston plate, so that the molten liquid inside the second hydraulic tank enters the first hydraulic tank through the flow-through groove. The molten liquid inside the first hydraulic tank increases, forcing the first piston plate and the pushing square rod to move outward. The pushing square rod moves outward, causing the clamping frame to rotate. At this time, the inner wall of the clamping frame is restricted by the support rod, and the end of the clamping frame away from the pushing square rod will expand outward. At the same time, the clamping frame will drive the outer shell to open at both ends. During this process, the limiting plate and the fixed L-shaped rod are directly fixed to the side of the mounting frame. When the glass bottle mold and the outer shell expand outward, the limiting plate will remain stationary. Through the application of the above components, when the glass bottle molds at both ends expand outward, the limiting plate will drive the inner glass bottle to complete demolding, preventing the glass bottle from sticking inside the glass bottle mold and affecting the demolding efficiency.

[0009] Preferably, the blowing and pressing mechanism further includes an inclined block fixedly connected to the side wall of the inner air outlet pipe. A fixed ring is fixedly connected to the outer wall of the air receiving valve. A torsion spring is fixedly connected to the side wall of the fixed ring. The end of the torsion spring away from the fixed ring is fixedly connected to the top of the inclined block.

[0010] Preferably, the blowing and pressing mechanism further includes an air delivery pipe penetrating and connected to the inner wall of the air intake valve. A spring telescopic rod is fixedly connected to the bottom of the linkage bracket. The end of the spring telescopic rod away from the linkage bracket is fixedly connected to a sliding plate. A supporting round rod is fixedly connected to the top of the sliding plate. The end of the supporting round rod away from the sliding plate is rotatably connected to a ball. Taking advantage of the characteristic that the above-mentioned air outlet outer pipe continuously moves downward during operation, an air outlet inner pipe and an air outlet outer pipe are arranged inside the device. After the air outlet outer pipe is inserted into the accommodating environment, the sliding plate will contact the top of the glass bottle mold and be restricted by the glass bottle mold and remain stationary. At this time, the top inclined block continuously moves downward under the drive of the linkage bracket and the linkage bracket. Finally, the bottom inclined surface of the inclined block contacts the outer wall of the ball. The force of the inclined block pressing down will force the inclined block to drive the air outlet inner pipe to rotate, so that the air outlet inner pipe coincides with the hole of the inclined block, forcing the air inside the air outlet inner pipe to be discharged outward through the coincident hole, providing a high-pressure gas for the glass blank. Through the design of the above-mentioned coincident hole, it effectively avoids the external glass melt entering the inside through the hole of the air outlet outer pipe during the early stage of blank shaping, causing pipeline blockage and affecting the blowing and pressing efficiency.

[0011] Preferably, the mold mechanism further includes an outer pushing spring sleeved on the outer wall of the sliding rod. The end of the sliding rod away from the sliding L-shaped rod is fixedly connected to a shaping slide plate. A prying plate is rotatably connected to the top of the shaping slide plate. A pulling frame is fixedly connected to the bottom of the prying plate. A second telescopic rod is rotatably connected to the outer wall of the pulling frame. Since most glass bottles are divided into two parts: a bottle body and a bottleneck, a prying plate and a shaping slide plate are arranged inside the device. Before using the device, ensure that the electric telescopic rod extends to the outermost periphery, and pour the glass solution to be shaped into the inside through the through hole at the top of the glass bottle mold. At this time, the bottleneck space of the glass bottle mold and the inner space of the shaping slide plate form an accommodating environment, presenting a state as shown in Figure 9 shown. The melt will temporarily exist inside the accommodating space. At this time, the electric telescopic rod drives the extrusion rod to slide downward through the connecting frame. The extrusion rod drives the air intake valve, the air outlet inner pipe, and the air outlet outer pipe to move downward synchronously, so that the air outlet outer pipe is inserted into the accommodating environment inside, forming a preliminary blank of the glass melt. As the electric telescopic rod contracts, the extrusion rod continues to move downward. After the extrusion rod moves downward for a certain distance, it will push the sliding L-shaped rod to move downward synchronously. The sliding L-shaped rod drives the shaping slide plate to slide downward along the inner wall of the glass bottle mold, stretching the length of the above blank. Finally, the external high-pressure gas is injected into the blank through the air delivery pipe and the air outlet outer pipe, causing the blank to expand and fit inside the glass bottle mold, completing the pressing and blowing process of the glass bottle. Through the application of the above components, the blank mold and the forming mold are combined, reducing the unnecessary process of flipping during equipment production.

[0012] Preferably, the mold mechanism further includes a slide rail fixedly connected to the bottom of the inner wall of the glass bottle mold. A spring slide rod is slidably connected to the inner wall of the slide rail, and the outer wall of the spring slide rod is slidably connected to the outer wall of the second telescopic rod. Utilizing the characteristic that the inner wall of the glass bottle mold moves downward verified by the above-mentioned shaping slide plate, a second telescopic rod and a spring slide rod are arranged inside the device. When the shaping slide plate moves upward along the inner wall of the glass bottle mold, the shaping slide plate will drive the second telescopic rod to move upward first, and at this time, the second telescopic rod extends. As the shaping slide plate moves upward, the second telescopic rod extends to the longest. At this time, the sliding rod continues to move upward, forcing the second telescopic rod to move upward along the outer wall of the spring slide rod. At this time, the second telescopic rod will bear the reaction force of the pulling of the spring slide rod, and this reaction force will act on the outer wall of the pulling frame, forcing the pulling frame to drive the prying plate to tilt upward to form an accommodating space; when a downward pulling force is generated on the sliding rod, the shaping slide plate will slide along the inner wall of the glass bottle mold. During the downward movement of the sliding rod, the prying plate remains vertical under the pulling of the spring slide rod, ensuring the shape and capacity of the bottom of the blank, and preventing the bottom of the glass bottle mold from expanding too fast, resulting in local rupture of the bottom of the bottom blank and affecting the pressing and blowing effect of the glass.

[0013] A manufacturing method of a lightweight glass bottle small-mouth pressing and blowing device includes the following steps:

[0014] S1: Before use, ensure that the electric telescopic rod extends to the outermost periphery, and pour the glass solution to be shaped into the inside through the through hole at the top of the glass bottle mold.

[0015] S2: The bottleneck space of the glass bottle mold and the inner space of the shaping slide plate form an accommodating environment, and the molten liquid will temporarily exist inside the accommodating space. The electric telescopic rod drives the extrusion rod to slide downward through the connecting frame, so that the air outlet outer tube is inserted into the accommodating environment to form a preliminary blank of the glass molten liquid.

[0016] S3: Finally, external high-pressure gas is injected into the blank through the gas transmission pipe and the air outlet outer tube, causing the blank to expand and fit inside the glass bottle mold to complete the pressing and blowing process of the glass bottle.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention utilizes that most glass bottles are divided into two parts: a bottle body and a bottleneck. A prying plate and a shaping slide plate are arranged inside the device. Before using the device, ensure that the electric telescopic rod extends to the outermost periphery, and pour the glass solution to be shaped into the inside through the through hole at the top of the glass bottle mold. At this time, the bottleneck space of the glass bottle mold and the inner space of the shaping slide plate form an accommodating environment, presenting as Figure 9In the shown state, the molten liquid will temporarily exist inside the accommodation space. At this time, the electric telescopic rod drives the extrusion rod to slide downward through the connecting frame. The extrusion rod drives the air connection valve, the inner air outlet pipe, and the outer air outlet pipe to move downward synchronously, so that the outer air outlet pipe is inserted into the accommodation environment, and the glass molten liquid forms a preliminary blank. As the electric telescopic rod contracts, the extrusion rod continues to move downward. After the extrusion rod moves downward for a certain distance, it will push the sliding L-shaped rod to move downward synchronously. The sliding L-shaped rod drives the plastic shaping slide plate to slide downward along the inner wall of the glass bottle mold through the sliding rod, stretching the length of the above blank. Finally, the external high-pressure gas is injected into the blank through the air delivery pipe and the outer air outlet pipe, causing the blank to expand and fit inside the glass bottle mold, completing the press-blow process of the glass bottle. Through the application of the above components, the blank mold and the forming mold are combined, reducing the unnecessary process of flipping during equipment production, avoiding blank deformation, and effectively reducing the probability of uneven thickness of the outer wall of the glass bottle during subsequent blow molding.

[0019] (2) The present invention utilizes the characteristic that the above plastic shaping slide plate moves downward along the inner wall of the glass bottle mold. There is a second telescopic rod and a spring slide rod inside the equipment. When the plastic shaping slide plate moves upward along the inner wall of the glass bottle mold, the plastic shaping slide plate will drive the second telescopic rod to move upward first. At this time, the second telescopic rod extends. As the plastic shaping slide plate moves upward, the second telescopic rod extends to the longest. At this time, the sliding rod continues to move upward, forcing the second telescopic rod to move upward along the outer wall of the spring slide rod. At this time, the second telescopic rod will bear the reaction force of the pulling of the spring slide rod. This reaction force will act on the outer wall of the pulling frame, forcing the pulling frame to drive the prying plate to tilt upward, forming an accommodation space. When a downward pulling force is generated on the sliding rod, the plastic shaping slide plate will slide along the inner wall of the glass bottle mold. During the downward movement of the sliding rod, the prying plate remains vertical under the pulling of the spring slide rod, ensuring the shape and capacity of the bottom of the blank, and avoiding the bottom of the glass bottle mold from expanding too fast, resulting in local rupture of the bottom blank and affecting the press-blow effect of the glass.

[0020] (3) The present invention utilizes the characteristic that the above outer air outlet pipe continuously moves downward during the working process. There is an inner air outlet pipe and an outer air outlet pipe inside the equipment. After the outer air outlet pipe is inserted into the accommodation environment, the sliding plate will contact the top of the glass bottle mold and be restricted by the glass bottle mold and remain stationary. At this time, the top inclined block continues to move downward under the drive of the linkage bracket and the linkage bracket. Finally, the bottom inclined surface of the inclined block contacts the outer wall of the ball. The force of the inclined block pressing down will force the inclined block to drive the inner air outlet pipe to rotate, so that the inner air outlet pipe coincides with the hole of the inclined block, forcing the air inside the inner air outlet pipe to be discharged outward through the coincident hole, providing a high-pressure gas for the glass blank. Through the design of the above coincident hole, it effectively avoids the external glass molten liquid entering the inside through the hole of the outer air outlet pipe during the early blank shaping, causing pipeline blockage and affecting the blow-press efficiency.

[0021] (4) After the device finishes blow molding, the electric telescopic rod stops running and waits for the glass bottle inside the glass bottle mold to cool and harden. After the glass bottle is cooled, the electric telescopic rod moves downward, driving the connecting frame to press the telescopic rod 1 and the piston plate 2, so that the molten liquid inside the hydraulic tank 2 enters the hydraulic tank 1 through the flow groove. The molten liquid inside the hydraulic tank 1 increases, forcing the piston plate 1 and the pushing square rod to move outward. When the pushing square rod moves outward, it will cause the pushing clamping frame to rotate. At this time, the inner wall of the clamping frame is restricted by the support rod, and the end of the clamping frame away from the pushing square rod will expand outward. At the same time, the clamping frame will drive the outer shell to open at both ends. During this process, the limit plate and the fixed L-shaped rod are directly fixed to the side of the mounting frame. When the glass bottle mold and the outer shell expand outward, the limit plate will remain stationary. Through the application of the above components, when the glass bottle molds at both ends expand outward, the limit plate will drive the inner glass bottle to complete demolding, avoiding the glass bottle sticking inside the glass bottle mold and affecting the demolding efficiency.

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1, please refer to Figure 1 - Figure 5 , the present invention is a lightweight glass bottle small-mouth press-blowing device, including a power mechanism 1. The power mechanism 1 further includes a mounting frame 11. The top of the mounting frame 11 is fixedly connected with an electric telescopic rod 12. The end of the electric telescopic rod 12 away from the mounting frame 11 is fixedly connected with a connecting frame 13. The inner wall of the through hole of the connecting frame 13 is fixedly connected with an extrusion rod 14. The top of the mounting frame 11 is fixedly connected with a fixing plate 15. The side wall of the fixing plate 15 is fixedly connected with a support rod 16. The outer wall of the support rod 16 is rotatably connected with a clamping frame 17;

[0039] Blowing and pressing mechanism 2, the blowing and pressing mechanism 2 includes a linkage bracket 21 fixedly connected to the top of the extrusion rod 14. One end of the linkage bracket 21 away from the extrusion rod 14 is rotatably connected to an air intake valve 22. The bottom of the air intake valve 22 is connected through with an inner air outlet pipe 23. The outer wall of the inner air outlet pipe 23 is rotatably connected to an outer air outlet pipe 24;

[0040] Mold mechanism 3, the mold mechanism 3 includes a housing 31 fixedly connected to the inner wall of the clamping frame 17. A glass bottle mold 32 is fixedly connected to the inner wall of the housing 31. The bottom of the extrusion rod 14 is slidably connected to a sliding L-shaped rod 33. One end of the sliding L-shaped rod 33 away from the extrusion rod 14 is fixedly connected to a sliding rod 34.

[0041] The power mechanism 1 further includes a piston plate one 19 slidably connected to the inner wall of the first hydraulic tank 18. A pushing square rod 110 is fixedly connected to the side wall of the piston plate one 19. One end of the pushing square rod 110 away from the piston plate one 19 is rotatably connected to the outer wall of the clamping frame 17. The top of the first hydraulic tank 18 is fixedly connected to a second hydraulic tank 111. A piston plate two 116 is slidably connected to the inner wall of the second hydraulic tank 111.

[0042] The power mechanism 1 further includes a piston plate two 116 slidably connected to the inner wall of the second hydraulic tank 111. A first telescopic rod 113 is fixedly connected to the top of the piston plate two 116. One end of the first telescopic rod 113 away from the piston plate two 116 is fixedly connected to the bottom of the connecting frame 13. A spring is fixedly connected to the bottom of the piston plate two 116. A flow channel 112 is opened at the bottom of the second hydraulic tank 111. A fixed L-shaped rod 114 is fixedly connected to the side wall of the mounting frame 11. One end of the fixed L-shaped rod 114 away from the mounting frame 11 is fixedly connected to a limiting plate 115. After the blow molding of the equipment is completed, the electric telescopic rod 12 stops running and waits for the glass bottle in the glass bottle mold 32 to cool and harden. After the glass bottle is cooled, the electric telescopic rod 12 moves downward, driving the connecting frame 13 to press the first telescopic rod 113 and the piston plate two 116, so that the molten liquid inside the second hydraulic tank 111 enters the first hydraulic tank 18 through the flow channel 112. The molten liquid inside the first hydraulic tank 18 increases, forcing the piston plate one 19 and the pushing square rod 110 to move outward. The pushing square rod 110 moves outward, driving the clamping frame 17 to rotate. At this time, the inner wall of the clamping frame 17 is restricted by the support rod 16, and the end of the clamping frame 17 away from the pushing square rod 110 will expand outward. At the same time, the clamping frame 17 will drive the housing 31 to open at both ends. During this process, the limiting plate 115 and the fixed L-shaped rod 114 are directly fixed to the side of the mounting frame 11. When the glass bottle mold 32 and the housing 31 expand outward, the limiting plate 115 will remain stationary. Through the application of the above components, when the glass bottle molds 32 at both ends expand outward, the limiting plate 115 will drive the inner glass bottle to complete demolding, avoiding the glass bottle sticking inside the glass bottle mold 32 and affecting the demolding efficiency.

[0043] Embodiment 2, please refer to Figure 6 - Figure 12 , the present invention is a lightweight glass bottle small-mouth press-blowing device. On the basis of Embodiment 1, the blowing and pressing mechanism 2 further includes an inclined block 25 fixedly connected to the side wall of the inner air outlet pipe 23. A fixing ring 26 is fixedly connected to the outer wall of the air connection valve 22. A torsion spring 27 is fixedly connected to the side wall of the fixing ring 26. One end of the torsion spring 27 away from the fixing ring 26 is fixedly connected to the top of the inclined block 25.

[0044] The blowing and pressing mechanism 2 further includes an air delivery pipe 28 connected through the inner wall of the air connection valve 22. A spring telescopic rod 29 is fixedly connected to the bottom of the linkage bracket 21. One end of the spring telescopic rod 29 away from the linkage bracket 21 is fixedly connected to a sliding plate 210. A support round rod 211 is fixedly connected to the top of the sliding plate 210. A ball 212 is rotatably connected to one end of the support round rod 211 away from the sliding plate 210. By using the characteristic that the air outlet outer pipe 24 continuously moves downward during the working process, an air outlet inner pipe 23 and an air outlet outer pipe 24 are arranged inside the device. After the air outlet outer pipe 24 is inserted into the accommodating environment, the sliding plate 210 will contact the top of the glass bottle mold 32 and be restricted by the glass bottle mold 32 and remain stationary. At this time, the top inclined block 25 continuously moves downward under the drive of the linkage bracket 21 and the linkage bracket 21. Finally, the bottom inclined surface of the inclined block 25 contacts the outer wall of the ball 212. The force of the inclined block 25 pressing down will force the inclined block 25 to drive the air outlet inner pipe 23 to rotate, so that the holes of the air outlet inner pipe 23 coincide with the holes of the inclined block 25, forcing the air inside the air outlet inner pipe 23 to be discharged outward through the coincident holes, providing a high-pressure gas for the glass blank. Through the design of the above coincident holes, it effectively avoids the external glass melt from entering the inside through the holes of the air outlet outer pipe 24 during the early plastic shaping of the blank, causing pipeline blockage and affecting the blowing and pressing efficiency.

[0045] The mold mechanism 3 further includes an outer push spring 35 sleeved on the outer wall of the sliding rod 34. One end of the sliding rod 34 away from the sliding L-shaped rod 33 is fixedly connected to a plastic shaping sliding plate 36. A prying plate 37 is rotatably connected to the top of the plastic shaping sliding plate 36. A pulling frame 38 is fixedly connected to the bottom of the prying plate 37. A second telescopic rod 39 is rotatably connected to the outer wall of the pulling frame 38. Since most glass bottles are divided into two parts: a bottle body and a bottleneck, a prying plate 37 and a plastic shaping sliding plate 36 are arranged inside the device. Before using the device, ensure that the electric telescopic rod 12 extends to the outermost periphery, and pour the glass solution to be shaped into the inside through the through hole at the top of the glass bottle mold 32. At this time, the bottleneck space of the glass bottle mold 32 and the inner space of the plastic shaping sliding plate 36 form an accommodating environment, presenting as Figure 9In the shown state, the molten liquid will temporarily exist inside the accommodating space. At this time, the electric telescopic rod 12 drives the extrusion rod 14 to slide downward through the connecting frame 13. The extrusion rod 14 drives the air connection valve 22, the inner air outlet pipe 23, and the outer air outlet pipe 24 to move downward synchronously, so that the outer air outlet pipe 24 is inserted into the accommodating environment, and the glass molten liquid forms a preliminary blank. As the electric telescopic rod 12 contracts, the extrusion rod 14 continues to move downward. After the extrusion rod 14 moves downward for a certain distance, it will push the sliding L-shaped rod 33 to move downward synchronously. The sliding L-shaped rod 33 drives the shaping slide plate 36 to slide downward along the inner wall of the glass bottle mold 32 through the sliding rod 34, stretching the length of the above blank. Finally, the external high-pressure gas is injected into the blank through the gas transmission pipe 28 and the outer air outlet pipe 24, causing the blank to expand and fit inside the glass bottle mold 32, completing the pressure-blowing process of the glass bottle. Through the application of the above components, the blank mold and the forming mold are combined, reducing the unnecessary process of flipping during equipment production, avoiding blank deformation, and effectively reducing the probability of uneven thickness of the outer wall of the glass bottle during subsequent blow molding.

[0046] The mold mechanism 3 further includes a slide rail 311 fixedly connected to the bottom of the inner wall of the glass bottle mold 32. A spring slide rod 310 is slidably connected to the inner wall of the slide rail 311. The outer wall of the spring slide rod 310 is slidably connected to the outer wall of the second telescopic rod 39. Utilizing the characteristic that the shaping slide plate 36 has been verified to move downward along the inner wall of the glass bottle mold 32, a second telescopic rod 39 and a spring slide rod 310 are arranged inside the equipment. When the shaping slide plate 36 moves upward along the inner wall of the glass bottle mold 32, the shaping slide plate 36 will drive the second telescopic rod 39 to move upward first. At this time, the second telescopic rod 39 extends. As the shaping slide plate 36 moves upward, the second telescopic rod 39 extends to the longest. At this time, the sliding rod 34 continues to move upward, forcing the second telescopic rod 39 to move upward along the outer wall of the spring slide rod 310. At this time, the second telescopic rod 39 will bear the reaction force of the pull of the spring slide rod 310, and this reaction force will act on the outer wall of the pulling frame 38, forcing the pulling frame 38 to drive the prying plate 37 to tilt upward, forming an accommodating space; when the sliding rod 34 generates a downward pulling force, the shaping slide plate 36 will slide along the inner wall of the glass bottle mold 32. During the downward movement of the sliding rod 34, the prying plate 37 remains vertical under the pull of the spring slide rod 310, ensuring the shape and capacity of the bottom of the blank, and avoiding excessive expansion of the bottom of the glass bottle mold 32, resulting in local rupture of the bottom of the bottom blank and affecting the pressure-blowing effect of the glass.

[0047] The manufacturing method of this glass bottle manufacturing device includes the following steps:

[0048] S1: Before use, ensure that the electric telescopic rod 12 extends to the outermost periphery, and pour the glass solution to be shaped into the glass bottle mold 32 through the through hole at the top.

[0049] S2: The bottleneck space of the glass bottle mold 32 and the internal space of the shaping slide plate 36 form an accommodation environment, and the molten liquid will temporarily exist inside the accommodation space. The electric telescopic rod 12 drives the extrusion rod 14 to slide downward through the connecting frame 13, so that the air outlet outer tube 24 is inserted into the accommodation environment, and the glass molten liquid forms a preliminary blank.

[0050] S3: Finally, the external high-pressure gas is injected into the blank through the gas transmission pipe 28 and the air outlet outer tube 24, causing the blank to expand and fit inside the glass bottle mold 32, completing the pressure-blowing process of the glass bottle.

[0051] A specific application of this embodiment is: Before use, ensure that the electric telescopic rod 12 extends to the outermost periphery, and pour the glass solution to be shaped into the inside through the through hole at the top of the glass bottle mold 32. At this time, the bottleneck space of the glass bottle mold 32 and the internal space of the shaping slide plate 36 form an accommodation environment, presenting a state as shown in Figure 9 the figure, and the molten liquid will temporarily exist inside the accommodation space. At this time, the electric telescopic rod 12 drives the extrusion rod 14 to slide downward through the connecting frame 13. The extrusion rod 14 drives the air connection valve 22, the air outlet inner tube 23 and the air outlet outer tube 24 to move downward synchronously, so that the air outlet outer tube 24 is inserted into the accommodation environment, and the glass molten liquid forms a preliminary blank. As the electric telescopic rod 12 contracts, the extrusion rod 14 continues to move downward, and after the extrusion rod 14 moves downward for a certain distance, it will push the sliding L-shaped rod 33 to move downward synchronously. The sliding L-shaped rod 33 drives the shaping slide plate 36 to slide downward along the inner wall of the glass bottle mold 32, stretching the length of the above blank. Finally, the external high-pressure gas is injected into the blank through the gas transmission pipe 28 and the air outlet outer tube 24, causing the blank to expand and fit inside the glass bottle mold 32, completing the pressure-blowing process of the glass bottle. Through the application of the above components, the blank mold and the forming mold are combined, reducing the unnecessary process of flipping during equipment production, avoiding blank deformation, and effectively reducing the probability of uneven thickness of the outer wall of the glass bottle during subsequent blow molding.

[0052] Taking advantage of the characteristic that the inner wall of the glass bottle mold 32 moves downward with the above-mentioned shaping slide plate 36, a second telescopic rod 39 and a spring slide rod 310 are provided inside the device. When the shaping slide plate 36 moves upward along the inner wall of the glass bottle mold 32, the shaping slide plate 36 will drive the second telescopic rod 39 to move upward first, and at this time, the second telescopic rod 39 extends. As the shaping slide plate 36 moves upward, the second telescopic rod 39 extends to the longest. At this time, the sliding rod 34 continues to move upward, which will force the second telescopic rod 39 to move upward along the outer wall of the spring slide rod 310. At this time, the second telescopic rod 39 will bear the reaction force of the pulling of the spring slide rod 310, and this reaction force will act on the outer wall of the pulling frame 38, forcing the pulling frame 38 to drive the prying plate 37 to tilt upward to form an accommodating space; when a downward pulling force is generated on the sliding rod 34, the shaping slide plate 36 will slide along the inner wall of the glass bottle mold 32. During the downward movement of the sliding rod 34, the prying plate 37 remains vertical under the pulling of the spring slide rod 310, ensuring the shape and capacity of the bottom of the blank, and preventing the bottom of the glass bottle mold 32 from expanding too fast, resulting in local cracking at the bottom of the bottom blank and affecting the pressing and blowing effect of the glass. Taking advantage of the characteristic that the above-mentioned air outlet outer tube 24 continuously moves downward during operation, an air outlet inner tube 23 and an air outlet outer tube 24 are provided inside the device. After the air outlet outer tube 24 is inserted into the accommodating environment, the sliding plate 210 will contact the top of the glass bottle mold 32 and be restricted by the glass bottle mold 32 and remain stationary. At this time, the top inclined block 25 continuously moves downward under the drive of the linkage bracket 21 and the linkage bracket 21. Finally, the bottom inclined surface of the inclined block 25 contacts the outer wall of the ball 212. The force of the inclined block 25 pressing downward will force the inclined block 25 to drive the air outlet inner tube 23 to rotate, making the air outlet inner tube 23 coincide with the hole of the inclined block 25, forcing the air inside the air outlet inner tube 23 to be discharged outward through the coincident hole, providing a high-pressure gas for the glass blank. Through the design of the above-mentioned coincident hole, it effectively avoids the external glass melt from entering the inside through the hole of the air outlet outer tube 24 during the early shaping of the blank, causing pipeline blockage and affecting the pressing and blowing efficiency.

[0053] After the device finishes blow molding, the electric telescopic rod 12 stops running and waits for the glass bottle inside the glass bottle mold 32 to cool and harden. After the glass bottle is cooled, the electric telescopic rod 12 moves downward, driving the connecting frame 13 to press the first telescopic rod 113 and the second piston plate 116, so that the molten liquid inside the second hydraulic tank 111 enters the first hydraulic tank 18 through the flow groove 112. The molten liquid inside the first hydraulic tank 18 increases, forcing the first piston plate 19 and the pushing square rod 110 to move outward. When the pushing square rod 110 moves outward, it will cause the pushing clamping frame 17 to rotate. At this time, the inner wall of the clamping frame 17 is restricted by the support rod 16, and the end of the clamping frame 17 away from the pushing square rod 110 will expand outward. At the same time, the clamping frame 17 will drive the outer shell 31 to open at both ends. During this process, the limit plate 115 and the fixed L-shaped rod 114 are directly fixed to the side of the mounting frame 11. When the glass bottle mold 32 and the outer shell 31 expand outward, the limit plate 115 will remain stationary. Through the application of the above components, when the glass bottle molds 32 at both ends expand outward, the limit plate 115 will drive the glass bottle inside to complete demolding, avoiding the glass bottle sticking inside the glass bottle mold 32 and affecting the demolding efficiency.
