Description

Technical Field

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

[0002] The small-mouth pressure-blowing process is an important part of glass bottle production, usually used to manufacture glass bottles or containers with smaller diameters. Usually, the production of glass bottles starts with raw materials. After the raw materials are mixed, they are melted at high temperature to form molten glass. The mixed raw materials are sent to the furnace and heated at high temperature to melt them into liquid glass. The melted glass is usually kept between 1400 and 1600 degrees Celsius. The molten glass is taken out through a pipe or mold to form a preliminary blank. The blank is placed in a preheated mold and then blown with a blowing device. When the blank enters the preheated mold, there is a blank flipping process.

[0003] This is an unnecessary action for the molding of glass bottles, because during the transfer process, the blank will further cool and harden, affecting the subsequent blow molding. In addition, during the flipping process, the shape of the blank and the internal expansion hole will bend. If blowing is performed at this time, the thickness of the outer wall of the glass bottle will be uneven. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a lightweight glass bottle small-mouth pressure-blowing device, comprising a power mechanism, the power mechanism also includes a mounting frame, the top of the mounting frame is fixedly connected to an electric telescopic rod, one end of the electric telescopic rod away from the mounting frame is fixedly connected to a connecting frame, the inner wall of the through hole of the connecting frame is fixedly connected to an extrusion rod, the top of the mounting frame is fixedly connected to a fixing plate, the side wall of the fixing plate is fixedly connected to a support rod, and the outer wall of the support rod is rotatably connected to a clamping frame;

[0005] The blowing mechanism includes a linkage bracket fixedly connected to the top of the extrusion rod, an end of the linkage bracket away from the extrusion rod is rotatably connected to an air receiving valve, the bottom of the air receiving valve is connected to an inner air outlet pipe, and the outer wall of the inner air outlet pipe is rotatably connected to an outer air outlet pipe;

[0006] The mold mechanism includes a shell fixedly connected to the inner wall of the clamping frame, a glass bottle mold fixedly connected to the inner wall of the shell, a sliding L-shaped rod slidably connected to the bottom of the extrusion rod, and a sliding rod fixedly connected to the end of the sliding L-shaped rod away from the extrusion rod.

[0007] Preferably, the power mechanism also includes a piston plate 1 fixedly connected to the inner wall of the hydraulic box 1, a pushing square rod fixedly connected to the side wall of the piston plate 1, an end of the pushing square rod away from the piston plate 1 is rotatably connected to the outer wall of the clamping frame, the top of the hydraulic box 1 is fixedly connected to the hydraulic box 2, and the piston plate 2 is slidably connected to the inner wall of the hydraulic box 2.

[0008] Preferably, the power mechanism also includes a piston plate 2 which is slidably connected to the inner wall of the hydraulic box 2, a telescopic rod 1 is fixedly connected to the top of the piston plate 2, an end of the telescopic rod 1 away from the piston plate 2 is fixedly connected to the bottom of the connecting frame, a spring is fixedly connected to the bottom of the piston plate 2, a flow groove is provided at the bottom of the hydraulic box 2, a fixed L-shaped rod is fixedly connected to the side wall of the mounting frame, and an end of the fixed L-shaped rod away from the mounting frame is fixedly connected to a limiting plate. After the equipment completes 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 completely cooled, the electric telescopic rod moves downward, driving the connecting frame to compress the telescopic rod 1 and the piston plate 2, so that the molten liquid inside the hydraulic box 2 passes through The circulation slot enters the interior of the hydraulic box 1, and the melt inside the hydraulic box 1 increases, forcing the piston plate 1 and the pushing square rod to move outward. The pushing square rod moves outward, which will push 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 to both ends. In this process, the limit plate and the fixed L-shaped rod are directly fixed on the side of the mounting frame. When the glass bottle mold and the outer shell expand outward, the limit plate will be in a stationary state. Through the application of the above components, when the glass bottle molds at both ends expand outward, the limit plate will drive the internal glass bottle to complete demoulding, thereby preventing the glass bottle from sticking to the inside of the glass bottle mold and affecting the demoulding efficiency.

[0009] Preferably, the blowing mechanism also includes a sloped block fixedly connected to the side wall of the inner air outlet tube, a fixing ring fixedly connected to the outer wall of the air receiving valve, a torsion spring fixedly connected to the side wall of the fixing ring, and one end of the torsion spring away from the fixing ring is fixedly connected to the top of the sloped block.

[0010] Preferably, the blowing mechanism also includes an air delivery pipe connected to the inner wall of the air receiving valve, a spring telescopic rod is fixedly connected to the bottom of the linkage bracket, an 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, and a ball is rotatably connected to the end of the supporting round rod away from the sliding plate. Utilizing the characteristic that the above-mentioned air outlet outer tube continuously moves downward during operation, an air outlet inner tube and an air outlet outer tube are arranged inside the equipment, and after the air outlet outer tube is inserted into the containing environment, the sliding plate will contact the top of the glass bottle mold and be limited by the restriction of the glass bottle mold. , and is in a stationary state. At this time, the top inclined plane block continues to move downward under the drive of the linkage bracket and the linkage bracket, and finally the bottom inclined plane of the inclined plane block contacts the outer wall of the ball. The downward pressure of the inclined plane block will force the inclined plane block to drive the air outlet inner tube to rotate, so that the holes of the air outlet inner tube and the inclined plane block coincide with each other, forcing the air inside the air outlet inner tube to be discharged outward through the coincident holes, providing a high-pressure gas for the glass blank. Through the design of the above-mentioned coincident holes, it is effectively avoided that the external molten glass enters the interior through the holes of the air outlet outer tube during the early stage of blank shaping, causing pipeline blockage and affecting the blowing efficiency.

[0011] Preferably, the mold mechanism also includes an outward push 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 molding slide plate, the top of the molding slide plate is rotatably connected to a prying plate, the bottom of the prying plate is fixedly connected to a pulling frame, and the outer wall of the pulling frame is rotatably connected to a telescopic rod 2. Most glass bottles are divided into two parts, a bottle body and a bottleneck. A prying plate and a molding slide plate are arranged inside the equipment. Before using the equipment, ensure that the electric telescopic rod is extended outward to the outermost periphery, and the glass solution with required plasticity is poured inward 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 internal space of the molding slide plate form a containing environment, presenting a Fig. 9 The state shown in the figure, and the molten liquid will temporarily exist inside the containing space. At this time, the electric telescopic rod drives the extrusion rod to slide downward through the connecting frame, and the extrusion rod drives the air receiving valve, the inner air outlet tube and the outer air outlet tube to move downward synchronously, so that the outer air outlet tube is inserted into the containing environment, so that the glass melt forms a preliminary blank. As the electric telescopic rod contracts, the extrusion rod continues to move downward, and after the extrusion rod moves down a certain distance, it will push the sliding L-shaped rod to move downward synchronously, and the sliding L-shaped rod drives the molding slide plate to slide downward along the inner wall of the glass bottle mold through the sliding rod, thereby lengthening the length of the above blank. Finally, the external high-pressure gas is injected into the blank through the gas pipe and the outer air outlet tube, so that the blank expands and fits inside the glass bottle mold, thereby completing the pressing and blowing process of the glass bottle. Through the application of the above components, the blank mold is combined with the forming mold to reduce the unnecessary process of flipping the equipment during production.

[0012] Preferably, the mold mechanism also includes a slide rail fixedly connected to the bottom of the inner wall of the glass bottle mold, a spring slide bar is slidably connected to the inner wall of the slide rail, and the outer wall of the spring slide bar is slidably connected to the outer wall of the telescopic rod 2. The above-mentioned molding slide has verified the characteristic that the inner wall of the glass bottle mold moves downward, and the telescopic rod 2 and the spring slide bar are arranged inside the equipment. When the molding slide moves up along the inner wall of the glass bottle mold, the molding slide will drive the telescopic rod 2 to move up first, and at this time the telescopic rod 2 will be extended. As the molding slide moves up, the telescopic rod 2 is extended to the longest. At this time, the sliding rod continues to move up, which will force the telescopic rod 2 to extend. The retractable rod 2 moves upward along the outer wall of the spring slide bar. At this time, the retractable rod 2 will bear the reaction force of the spring slide bar, and the 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 the sliding rod generates a downward pulling force, the molding slide plate will slide along the inner wall of the glass bottle mold. In the process of the sliding rod moving downward, the prying plate remains in a vertical state under the pull of the spring slide bar, thereby ensuring the shape and capacity of the bottom of the blank, avoiding the bottom of the glass bottle mold from expanding too quickly, resulting in local rupture of the bottom of the bottom blank, and affecting the pressing and blowing effect of the glass.

[0013] A method for manufacturing a lightweight glass bottle small-mouth pressure-blowing device comprises the following steps:

[0014] S1: Before use, ensure that the electric telescopic rod is extended outward to the outermost periphery, and pour the glass solution with the required plasticity into the glass bottle through the through hole at the top of the glass bottle mold;

[0015] S2: The bottleneck space of the glass bottle mold and the internal space of the molding slide form a containing environment, and the molten liquid will temporarily exist inside the containing space. The electric telescopic rod drives the extrusion rod to slide downward through the connecting frame, so that the outer exhaust pipe is inserted into the containing environment, so that the glass melt forms a preliminary blank;

[0016] S3: Finally, the external high-pressure gas is injected into the blank through the gas supply pipe and the gas outlet pipe, so that the blank expands and fits inside the glass bottle mold, completing the glass bottle pressure blowing process.

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

[0018] (1) The present invention utilizes that most glass bottles are divided into two parts: the bottle body and the bottleneck. A prying plate and a shaping slide plate are arranged inside the device. Before using the device, the electric telescopic rod is extended outward to the outermost periphery, and the glass solution with the required plasticity is poured inward 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 internal space of the shaping slide plate form a containing environment, presenting a Fig. 9The state shown in the figure, and the molten liquid will temporarily exist in the containing space. At this time, the electric telescopic rod drives the extrusion rod to slide downward through the connecting frame, and the extrusion rod drives the air receiving valve, the inner air outlet tube and the outer air outlet tube to move downward synchronously, so that the outer air outlet tube is inserted into the containing environment, so that the glass melt forms a preliminary blank. As the electric telescopic rod contracts, the extrusion rod continues to move downward, and after the extrusion rod moves down a certain distance, it will push the sliding L-shaped rod to move downward synchronously, and the sliding L-shaped rod drives the molding slide plate to slide downward along the inner wall of the glass bottle mold through the sliding rod, lengthening the length of the above blank. Finally, the external high-pressure gas is injected into the blank through the gas pipe and the outer air outlet tube to expand the blank and fit it inside the glass bottle mold to complete the pressing and blowing process of the glass bottle. Through the application of the above components, the blank mold is combined with the forming mold, the unnecessary process of flipping during equipment production is reduced, the blank is avoided from deformation, and the probability of uneven thickness of the outer wall of the glass bottle during subsequent blow molding is effectively reduced.

[0019] (2) The present invention utilizes the above-mentioned molding slide plate to verify the characteristic that the inner wall of the glass bottle mold moves downward. A telescopic rod 2 and a spring slide bar are arranged inside the device. When the molding slide plate moves upward along the inner wall of the glass bottle mold, the molding slide plate will drive the telescopic rod 2 to move upward first, and at this time the telescopic rod 2 is extended. As the molding slide plate moves upward, the telescopic rod 2 is extended to the longest. At this time, the sliding rod continues to move upward, forcing the telescopic rod 2 to move upward along the outer wall of the spring slide bar. At this time, the telescopic rod 2 will bear the reaction force of the spring slide bar pulling, and the 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 the sliding rod generates a downward pulling force, the molding 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 in a vertical state under the pulling of the spring slide bar, thereby ensuring the shape and capacity of the bottom of the blank and preventing the bottom of the glass bottle mold from expanding too quickly, resulting in local rupture of the bottom of the bottom blank, affecting the glass blowing effect.

[0020] (3) The present invention utilizes the characteristic that the above-mentioned air outlet outer tube continuously moves downward during operation, and an air outlet inner tube and an air outlet outer tube are arranged inside the equipment. After the air outlet outer tube is inserted into the containing environment, the sliding plate will contact the top of the glass bottle mold and be restricted by the limitation of the glass bottle mold and be in a stationary state. At this time, the top inclined plane block continues to move downward under the drive of the linkage bracket and the linkage bracket, and finally the bottom inclined plane of the inclined plane block contacts the outer wall of the ball. The downward pressure of the inclined plane block will force the inclined plane block to drive the air outlet inner tube to rotate, so that the holes of the air outlet inner tube and the inclined plane block overlap, forcing the air inside the air outlet inner tube to be discharged outward through the overlapping holes, providing a high-pressure gas for the glass blank. Through the design of the above-mentioned overlapping holes, it is effectively avoided that the external molten glass enters the interior through the holes of the air outlet outer tube during the early stage of blank shaping, causing pipeline blockage and affecting the blowing efficiency.

[0021] (4) After the blow molding is completed, 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 completely cooled, the electric telescopic rod moves downward, driving the connecting frame to compress the telescopic rod 1 and the piston plate 2, so that the molten liquid inside the hydraulic box 2 enters the hydraulic box 1 through the circulation groove. The molten liquid inside the hydraulic box 1 increases, forcing the piston plate 1 and the pushing square rod to move outward. The pushing square rod moves outward and drives 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 to both ends. In 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 be in a stationary state. Through the application of the above components, when the glass bottle molds at both ends expand outward, the limit plate will drive the internal glass bottle to complete demolding, thereby preventing the glass bottle from sticking to the inside of the glass bottle mold and affecting the demolding efficiency.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The blowing mechanism 2 includes a linkage bracket 21 fixedly connected to the top of the extrusion rod 14, and the end of the linkage bracket 21 away from the extrusion rod 14 is rotatably connected to the air receiving valve 22, and the bottom of the air receiving valve 22 is connected to the air outlet inner tube 23, and the outer wall of the air outlet inner tube 23 is rotatably connected to the air outlet outer tube 24;

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

[0041] The power mechanism 1 also includes a piston plate 19 fixedly connected to the inner wall of a hydraulic box 18 and slidably connected to a pushing square rod 110 fixedly connected to the side wall of the piston plate 19, and one end of the pushing square rod 110 away from the piston plate 19 is rotatably connected to the outer wall of the clamping frame 17, a hydraulic box 2 111 is fixedly connected to the top of the hydraulic box 18, and a piston plate 2 116 is slidably connected to the inner wall of the hydraulic box 2 111.

[0042] The power mechanism 1 also includes a piston plate 116 slidably connected to the inner wall of the hydraulic box 111, a telescopic rod 113 is fixedly connected to the top of the piston plate 116, and the end of the telescopic rod 113 away from the piston plate 116 is fixedly connected to the bottom of the connecting frame 13, and the bottom of the piston plate 116 is fixedly connected to a spring. A flow groove 112 is provided at the bottom of the hydraulic box 111, and a fixed L-shaped rod 114 is fixedly connected to the side wall of the mounting frame 11, and the end of the fixed L-shaped rod 114 away from the mounting frame 11 is fixedly connected to a limiting plate 115. After the equipment completes 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 completely cooled, the electric telescopic rod 12 moves downward, driving the connecting frame 13 to compress the telescopic rod 113 and the piston plate 116, so that the melt inside the hydraulic box 111 The melt enters the hydraulic box 18 through the circulation groove 112. The melt inside the hydraulic box 18 increases, forcing the piston plate 19 and the pushing square rod 110 to move outward. The pushing square rod 110 moves outward, which will push 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 outer shell 31 to open to both ends.

When the glass bottle mold 32 and the outer shell 31 expand outward, the limit plate 115 will be in a stationary state. Through the application of the above-mentioned components, when the glass bottle molds 32 at both ends expand outward, the limit plate 115 will drive the internal glass bottle to complete demoulding, thereby preventing the glass bottle from sticking to the inside of the glass bottle mold 32 and affecting the demoulding efficiency.

[0043] For example 2, please refer to Figure 6 - Fig.12 The present invention is a lightweight glass bottle small-mouth pressure-blowing device. On the basis of the first embodiment, the blowing mechanism 2 also includes a slope block 25 fixedly connected to the side wall of the air outlet inner tube 23, a fixing ring 26 is fixedly connected to the outer wall of the air receiving valve 22, and a torsion spring 27 is fixedly connected to the side wall of the fixing ring 26. The end of the torsion spring 27 away from the fixing ring 26 is fixedly connected to the top of the slope block 25.

[0044] The blowing mechanism 2 also includes an air delivery pipe 28 connected to the inner wall of the air receiving valve 22, a spring telescopic rod 29 is fixedly connected to the bottom of the linkage bracket 21, and a sliding plate 210 is fixedly connected to the end of the spring telescopic rod 29 away from the linkage bracket 21, and a supporting round rod 211 is fixedly connected to the top of the sliding plate 210, and a ball 212 is rotatably connected to the end of the supporting round rod 211 away from the sliding plate 210. 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 arranged inside the equipment. After the air outlet outer tube 24 is inserted into the containing environment, the sliding plate 210 will contact the top of the glass bottle mold 32 and limit the glass bottle mold 32. The glass bottle mold 32 is restricted and is in a stationary state. At this time, the top inclined surface block 25 continues to move downward under the drive of the linkage bracket 21 and the linkage bracket 21, and finally the bottom inclined surface of the inclined surface block 25 contacts the outer wall of the ball 212. The downward pressure of the inclined surface block 25 will force the inclined surface block 25 to drive the air outlet inner tube 23 to rotate, so that the holes of the air outlet inner tube 23 and the inclined surface block 25 overlap, forcing the air inside the air outlet inner tube 23 to be discharged outward through the overlapping holes, providing a high-pressure gas for the glass blank. Through the design of the above-mentioned overlapping holes, it is effectively avoided that the external molten glass enters the interior through the holes of the air outlet outer tube 24 during the early stage of blank shaping, causing pipeline blockage and affecting the blowing efficiency.

[0045] The mold mechanism 3 also includes an outward push spring 35 sleeved on the outer wall of the sliding rod 34, and the end of the sliding rod 34 away from the sliding L-shaped rod 33 is fixedly connected to a molding slide 36, and the top of the molding slide 36 is rotatably connected to a prying plate 37, and the bottom of the prying plate 37 is fixedly connected to a pulling frame 38, and the outer wall of the pulling frame 38 is rotatably connected to a telescopic rod 2 39. Most glass bottles are divided into two parts, a bottle body and a bottleneck. A prying plate 37 and a molding slide 36 are arranged inside the device. Before using the device, ensure that the electric telescopic rod 12 is extended outward to the outermost periphery, and the required plastic glass solution is poured inward 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 molding slide 36 form a containing environment, presenting a Fig. 9The state shown in the figure, and the molten glass will temporarily exist in the accommodation space. At this time, the electric telescopic rod 12 drives the extrusion rod 14 to slide downward through the connecting frame 13, and the extrusion rod 14 drives the air receiving 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, so that the glass melt forms a preliminary blank. As the electric telescopic rod 12 shrinks, the extrusion rod 14 continues to move downward, and after the extrusion rod 14 moves downward for a distance, it pushes the sliding L-shaped rod 33 to move downward synchronously, and the sliding L-shaped rod 33 passes through the The sliding rod 34 drives the molding slide plate 36 to slide downward along the inner wall of the glass bottle mold 32, lengthening the length of the above blank. Finally, the external high-pressure gas is injected into the blank through the gas supply pipe 28 and the gas outlet outer pipe 24, so that the blank expands and fits 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 molding mold are combined to reduce the unnecessary process of flipping the equipment during production, avoid deformation of the blank, and effectively reduce the probability of uneven thickness of the outer wall of the glass bottle during subsequent blow molding.

[0046] The mold mechanism 3 also includes a slide rail 311 fixedly connected to the bottom of the inner wall of the glass bottle mold 32, and a spring slide bar 310 is slidably connected to the inner wall of the slide rail 311, and the outer wall of the spring slide bar 310 is slidably connected to the outer wall of the telescopic rod 2 39. The above-mentioned molding slide plate 36 has verified the characteristic that the inner wall of the glass bottle mold 32 moves downward, and the telescopic rod 2 39 and the spring slide bar 310 are arranged inside the equipment. When the molding slide plate 36 moves up along the inner wall of the glass bottle mold 32, the molding slide plate 36 will drive the telescopic rod 2 39 to move up first, and at this time the telescopic rod 2 39 will be extended. As the molding slide plate 36 moves up, the telescopic rod 2 39 is extended to the longest, and at this time the sliding rod 34 continues to move up. The telescopic rod 39 is forced to move upward along the outer wall of the spring slide bar 310. At this time, the telescopic rod 39 will bear the reaction force of the spring slide bar 310, and the 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 the sliding rod 34 generates a downward pulling force, the molding slide plate 36 will slide along the inner wall of the glass bottle mold 32. In the process of the sliding rod 34 moving downward, the prying plate 37 remains in a vertical state under the pulling of the spring slide bar 310, thereby ensuring the shape and capacity of the bottom of the blank, avoiding the bottom of the glass bottle mold 32 from expanding too quickly, resulting in local rupture of the bottom of the bottom blank, and affecting the pressing and blowing effect of the glass.

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

[0048] S1: Before use, ensure that the electric telescopic rod 12 is extended outward to the outermost periphery, and pour the glass solution with the required plasticity 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 inner space of the molding slide plate 36 form a containing environment, and the molten liquid will temporarily exist in the containing space. The electric telescopic rod 12 drives the extrusion rod 14 to slide downward through the connecting frame 13, so that the outer gas outlet tube 24 is inserted into the containing environment, so that the glass melt forms a preliminary blank;

[0050] S3: Finally, the external high-pressure gas is injected into the blank through the gas supply pipe 28 and the gas outlet outer pipe 24, so that the blank expands and fits inside the glass bottle mold 32, completing the glass bottle pressure-blowing process.

[0051] A specific application of this embodiment is: before use, ensure that the electric telescopic rod 12 is extended outward to the outermost periphery, and the glass solution with the required plasticity is poured into the glass bottle mold 32 through the through hole at the top. At this time, the bottleneck space of the glass bottle mold 32 and the internal space of the molding slide 36 form a containing environment, presenting as follows Fig. 9 The state shown in the figure, and the molten glass will temporarily exist in the accommodation space. At this time, the electric telescopic rod 12 drives the extrusion rod 14 to slide downward through the connecting frame 13, and the extrusion rod 14 drives the air receiving 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, so that the glass melt forms a preliminary blank. As the electric telescopic rod 12 shrinks, the extrusion rod 14 continues to move downward, and after the extrusion rod 14 moves downward for a distance, it pushes the sliding L-shaped rod 33 to move downward synchronously, and the sliding L-shaped rod 33 passes through the The sliding rod 34 drives the molding slide plate 36 to slide downward along the inner wall of the glass bottle mold 32, lengthening the length of the above blank. Finally, the external high-pressure gas is injected into the blank through the gas supply pipe 28 and the gas outlet outer pipe 24, so that the blank expands and fits 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 molding mold are combined to reduce the unnecessary process of flipping the equipment during production, avoid deformation of the blank, and effectively reduce the probability of uneven thickness of the outer wall of the glass bottle during subsequent blow molding.

[0052] The above-mentioned shaping slide 36 has verified the characteristic that the inner wall of the glass bottle mold 32 moves downward. A telescopic rod 2 39 and a spring slide 310 are arranged inside the device. When the shaping slide 36 moves upward along the inner wall of the glass bottle mold 32, the shaping slide 36 will drive the telescopic rod 2 39 to move upward first, and at this time the telescopic rod 2 39 will extend. As the shaping slide 36 moves upward, the telescopic rod 2 39 extends to the longest. At this time, the sliding rod 34 continues to move upward, which will force the telescopic rod 2 39 to move upward along the outer wall of the spring slide 310. When the sliding rod 34 moves downward, the telescopic rod 39 will bear the reaction force of the spring slide bar 310, and the 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 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 in a vertical state under the pulling of the spring slide bar 310, thereby ensuring the shape and capacity of the bottom of the blank and avoiding the glass bottle mold 32 The bottom expands too fast, causing local cracks at the bottom of the bottom blank, affecting the glass blowing effect. Taking advantage of the fact that the above-mentioned air outlet outer tube 24 continues to move downward during operation, an air outlet inner tube 23 and an air outlet outer tube 24 are arranged inside the equipment. After the air outlet outer tube 24 is inserted into the accommodation 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 be in a stationary state. At this time, the top inclined surface block 25 continues to move downward under the drive of the linkage bracket 21 and the linkage bracket 21. Finally, the bottom slope of the inclined plane block 25 contacts the outer wall of the ball 212. The downward pressure of the inclined plane block 25 will force the inclined plane block 25 to drive the inner air outlet tube 23 to rotate, so that the holes of the inner air outlet tube 23 and the inclined plane block 25 overlap, forcing the air inside the inner air outlet tube 23 to be discharged outward through the overlapping holes, providing a high-pressure gas for the glass blank. Through the design of the above-mentioned overlapping holes, it is effectively avoided that the external molten glass enters the interior through the holes of the outer air outlet tube 24 during the early stage of blank shaping, causing pipeline blockage and affecting the blowing efficiency.

[0053] After the equipment completes 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 completely cooled, the electric telescopic rod 12 moves downward, driving the connecting frame 13 to press the telescopic rod 113 and the piston plate 2 116, so that the molten liquid inside the hydraulic box 2 111 enters the hydraulic box 18 through the flow groove 112. The molten liquid inside the hydraulic box 18 increases, forcing the piston plate 19 and the pushing square rod 110 to move outward, pushing the square rod 110 outward, and pushing the clamping frame 17 to rotate. At this time, the inner wall of the clamping frame 17 is supported. Due to the restriction of the rod 16, the end of the clamping frame 17 away from the pushing square rod 110 will expand outward, and at the same time, the clamping frame 17 will drive the shell 31 to open to both ends. In 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 shell 31 expand outward, the limit plate 115 will be in a stationary state. 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 internal glass bottle to complete demoulding, thereby preventing the glass bottle from sticking to the inside of the glass bottle mold 32 and affecting the demoulding efficiency.
