Description

Technical Field

[0001] The invention relates to the technical field of glass blowing, in particular to a rough blank shaping mold for intelligent processing of heat-resistant constant-temperature glass products. Background Art

[0002] Glass blowing, as an ancient and traditional process in the field of glass molding, is mainly divided into two methods: manual blowing and machine blowing. Manual blowing has a long history and is a classic process for molding glass and other materials. However, in today's production practice, with the exception of a small number of arts and crafts and large products that require the craftsman's manual skills to impart unique artistic value and meet complex production requirements, manual blowing is still used. Automated machine blowing has become the mainstream method of glass blowing.

[0003] Mechanical blowing relies on automated mechanical equipment to complete the entire blowing process; first, the glass raw materials are melted in a high-temperature furnace and converted into liquid glass with good fluidity. Then the feeder and scissor mechanism shear the molten liquid glass into droplets. The droplets are guided to the pressure head through the guide trough. When the liquid glass drop reaches the pressure head position, the pressure head moves vertically upward and squeezes the suction head above, so that the liquid glass is squeezed into a cake shape. The glass cake is then transferred to the blowing machine, which blows the glass cake into a conical bubble. When the prototype bubble is formed, the clamping mold clamps the prototype bubble into the shaping mold. After a short blowing and shaping process, the shaping mold is opened, and a transparent solid glass semi-finished product is completed. The subsequent glass products need to undergo subsequent annealing, grinding, polishing and other processing steps before they can become final qualified products.

[0004] A seam line is a mark that appears during the molding process of glass bottles and jars. It stems from the unique structure of the molding mold. Because the molding mold is composed of multiple pieces, during the production process, when the liquid glass flows to the joint of the mold, the flow is interrupted, resulting in a seam line on the finished product. The seam line appears as a thin line on the surface of the glass product. For example, early mold designs often used two-piece molds. Workers operate a handle to close the mold before the blow molding process begins. The resulting glass bottle will have a noticeable seam line on the bottom.

[0005] The presence of seams has a certain degree of negative impact on the quality and aesthetics of glass products. In terms of quality, the presence of seams reduces the strength of glass products, significantly increasing their risk of breakage. When glass products are subjected to external impact or temperature fluctuations, the seams easily become weak areas where stress concentrates, much like a gap in a solid city wall, making the entire structure most vulnerable to damage. In terms of aesthetics, noticeable seams can ruin the overall visual effect of glass products, significantly reducing their value.

[0006] In view of this, in order to overcome the above technical problems, the present invention proposes a rough blank shaping mold for intelligent processing of heat-resistant constant temperature glass products, which solves the above technical problems. Summary of the Invention

[0007] In order to make up for the shortcomings of the existing technology, the present invention proposes a rough molding mold for the intelligent processing of heat-resistant constant-temperature glass products. The present invention cooperates with the connecting rod and the inner mold, so that the driving motor can drive the inner mold to rotate through the connecting rod, that is, when the blowing head blows the conical bubble in the molding mold, the driving motor can drive the inner mold to rotate. At this time, friction contact occurs between the inner wall of the inner mold and the liquid glass. The friction force of the friction contact will cause the outer wall of the high-temperature liquid glass to flow in the direction of rotation of the mold, so that the high-temperature liquid glass flowing to the gap between the inner mold can be pushed by the friction force to flow smoothly inside the inner mold, reducing the interruption of glass flow and reducing the obviousness of the seam line. It not only improves the strength of the glass product and reduces its breakage risk, but also improves the overall visual effect of the glass product.

[0008] The technical solution adopted by the present invention to solve its technical problems is that the rough blank shaping mold for intelligent processing of heat-resistant constant temperature glass products described in the present invention includes a body and a shaping mold installed on the upper end of the body; the shaping mold also includes an outer mold and an inner mold; the number of the outer mold and the inner mold is set to two; the outer mold and the body are connected by a hydraulic push rod; the inner mold is rotatably connected to the inner wall of the outer mold; a connecting rod is provided under the shaping mold; a through groove is opened inside the body; the lower end of the body is rotatably connected to a gear ring; the connecting rod is slidably connected to the gear ring; a driving motor is fixedly installed at the lower end of the body; the output shaft of the driving motor is fixedly connected to a transmission gear; the transmission gear and the gear ring are connected by a transmission belt; an electric push rod is provided under the connecting rod; one end of the electric push rod is rotatably connected to the connecting rod, and the other end is fixed to the body; a fixing unit is installed on the inner wall of the outer mold, and the outer mold and the inner mold are connected by the fixing unit.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention cooperates with the connecting rod and the inner mold so that the driving motor can drive the inner mold to rotate through the connecting rod. That is, when the blowing head blows the conical bubble in the shaping mold, the driving motor can drive the inner mold to rotate. At this time, frictional contact occurs between the inner wall of the inner mold and the liquid glass. The friction force of the frictional contact causes the outer wall of the high-temperature liquid glass to flow in the direction of rotation of the mold, so that the high-temperature liquid glass flowing to the gap between the inner mold can be pushed by the friction force to flow smoothly inside the inner mold, reducing the interruption of glass flow and the visibility of the seam line.

At this time, the user only needs to rotate the inner mold to remove the inner mold and replace the required inner mold, so there is no need to disassemble and replace the entire shaping mold, which greatly reduces the difficulty of disassembling and replacing the shaping mold. It not only reduces the labor intensity of the operator, but also improves the efficiency of disassembling and replacing the shaping mold, thereby improving the production efficiency of the glass bottle.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figures 1 to 6As shown, the rough blank shaping mold for intelligent processing of heat-resistant constant temperature glass products described in the present invention includes a body 1 and a shaping mold 2 installed on the upper end of the body 1; the shaping mold 2 also includes an outer mold 21 and an inner mold 22; the number of the outer mold 21 and the inner mold 22 is set to two; the outer mold 21 is connected to the body 1 through a hydraulic push rod 11; the inner mold 22 is rotatably connected to the inner wall of the outer mold 21; a connecting rod 12 is provided below the shaping mold 2; a through groove 121 is opened inside the body 1; the lower end of the body 1 is rotatably connected to a gear ring 14; the connecting rod 12 is slidably connected to the gear ring 14; a driving motor 15 is fixedly installed at the lower end of the body 1; the output shaft of the driving motor 15 is fixedly connected to a transmission gear 151; the transmission gear 151 and the gear ring 14 are connected by a transmission belt 152; an electric push rod 13 is provided below the connecting rod 12; one end of the electric push rod 13 is rotatably connected to the connecting rod 12, and the other end is fixedly connected to the body 1; a fixing unit is installed on the inner wall of the outer mold 21, and the outer mold 21 and the inner mold 22 are connected by the fixing unit.

[0029] As an embodiment of the present invention, the fixing unit includes a fixing rod 23; a fixing groove 231 is provided on the inner wall of the outer mold 21; the fixing rod 23 is slidingly and sealingly connected in the fixing groove 231; the fixing rod 23 and the bottom of the fixing groove 231 are connected by a fixing spring 232; a card groove 233 is provided on the outer wall of the inner mold 22 and is opposite to the fixing groove 231; a sealing groove 24 is provided on the inner wall of the outer mold 21 and is connected to the fixing groove 231; a sealing rod 241 is slidingly and sealingly connected in the sealing groove 24.

[0030] As an embodiment of the present invention, the fixing unit also includes an insertion rod 16; a circular groove 161 is provided at the upper end of the connecting rod 12; the insertion rod 16 is slidingly and sealingly connected in the circular groove 161; the insertion rod 16 and the bottom of the circular groove 161 are connected by a support spring 162; the lower end surface of the inner mold 22 is provided with a slot matching the circular groove 161; the bottom of the circular groove 161 is inlaid with a pressure sensor 163.

[0031] As an embodiment of the present invention, a heat-resistance plate 221 is fixedly connected to the inner wall of the inner mold 22; the heat-resistance plate 221 is made of graphite material.

[0032] During the molding process of glass bottles and jars, seams appear, which have a certain degree of negative impact on the quality and aesthetics of the glass products. From a quality perspective, the appearance of seams can reduce the strength of the glass products and significantly increase the risk of breakage. When glass products are subjected to external impact or temperature changes, the seams are very likely to become weak areas where stress is concentrated, just like a gap in a solid city wall, becoming the most vulnerable point of the entire structure. From an aesthetic perspective, obvious seams will destroy the overall visual effect of the glass products, greatly reducing their ornamental value.

[0033] In the prior art, there is also a blowing head that clamps the conical bubble through a clamping device and rotates it in the shaping mold 2 for blowing. However, the clamping points of the clamping device will hinder the flow of glass, causing the glass to be unevenly distributed in these parts. Moreover, as the rotation proceeds, the glass around the clamping points will be locally deformed due to repeated squeezing and stretching, further affecting the overall uniformity of the glass product. In addition, when the blowing head drives the conical bubble to rotate through the clamping device, the stability of the entire system is poor, that is, the clamping device is prone to loosening, shaking and other problems during the rotation process, resulting in an unstable rotation trajectory of the conical bubble, affecting the molding quality of the glass product.

[0034] To this end, the present invention cooperates with the connecting rod 12 and the inner mold 22 so that the driving motor 15 can drive the inner mold 22 to rotate through the connecting rod 12. That is, when the blowing head blows the conical bubble in the shaping mold 2, the driving motor 15 can drive the inner mold 22 to rotate. At this time, frictional contact occurs between the inner wall of the inner mold 22 and the liquid glass. The friction force of the frictional contact will cause the outer wall of the high-temperature liquid glass to flow in the direction of rotation of the mold, so that the high-temperature liquid glass flowing to the joint gap of the inner mold 22 can be pushed by the friction force to flow smoothly inside the inner mold 22, reducing the interruption of glass flow and the obviousness of the joint line. This not only improves the strength of the glass product and reduces its risk of breakage, but also improves the overall visual effect of the glass product.

[0035] During use, the external flame spraying device preheats the inner walls of the two inner molds 22, and then the blowing head clamps the conical bubble to the top of the machine body 1 through the clamping device, so that the conical bubble is located between the two adjacent inner molds 22, and then the hydraulic push rod 11 is controlled to extend, so that the adjacent hydraulic push rods 11 can push the two adjacent outer molds 21 to move towards each other, so that the two adjacent outer molds 21 drive the two inner molds 22 connected by the inner wall rotation to move closer to each other until the two adjacent outer molds 21 contact each other. At this time, the two adjacent inner molds 22 also contact each other under the push of the outer mold 21, so that the two outer molds 21 and the two inner molds 22 are in a mold closing state, and then the mold closing is controlled. At this time, the conical bubble formed by the high-temperature liquid glass is wrapped by the two adjacent inner molds 22. At this time, the blowing head is controlled to blow air into the conical bubble, thereby starting to blow the glass product.

[0036] Since the inner wall of the inner mold 22 is fixedly connected with a heat-resistant plate 221, and the heat-resistant plate 221 is made of graphite material, graphite material is a material with excellent heat-resistant effect and low thermal conductivity, which can prevent heat conduction. Therefore, during the blowing process of the glass cone bubble, the heat-resistant plate 221 of the inner mold 22 can effectively prevent the heat in the inner mold 22 from being quickly conducted away, so that the blown cone bubble can maintain a suitable molding temperature in the inner mold 22, thereby facilitating the uniform cooling and molding of the glass, avoiding defects such as cracks and deformation in glass products caused by rapid local temperature changes, and ensuring that all parts of the blown glass product can be cooled slowly as expected, ensuring the accuracy and integrity of the product shape.

[0037] Since the heat-resisting plate 221 reduces the rapid conduction of heat from the inner mold 22, the additional heat input required to maintain the appropriate temperature of the glass cone bulb during the entire blowing process is reduced. That is, in actual production, whether heat is supplemented by external heating equipment or the temperature is adjusted by other means, the heat-resisting plate 221 can reduce energy consumption by virtue of its excellent heat-resisting properties, thereby achieving the purpose of energy conservation. This energy-saving effect not only helps to reduce production costs, but also conforms to the concept of sustainable development, bringing both economic and environmental benefits to the enterprise.

[0038] In addition, the graphite material also has stable chemical properties and anti-oxidation performance, that is, in a high-temperature glass blowing environment, the heat-resistant plate 221 in contact with the high-temperature conical bubble will not chemically react with the glass raw material or the surrounding gas, nor will it be easily oxidized. This not only reduces the replacement frequency caused by mold corrosion or oxidation, reduces production costs, and ensures the molding quality of glass products, but also blocks the diffusion of heat between the two inner molds 22, thereby reducing the heat transfer to the outer mold 21 and reducing the heat transfer to the hydraulic oil in the fixed groove 231, thereby slowing down the problem of aging of the hydraulic oil due to heat, thereby improving the use effect and service life of the hydraulic oil, and further enhancing the practicality of the present invention.

[0039] Before blowing glass products, the user first controls the electric push rod 13 to operate, so that the electric push rod 13 can push the connecting rod 12 to rise, so that the connecting rod 12 rises relative to the gear ring 14 along the through groove 121, so that the connecting rod 12 is inserted between the two adjacent outer molds 21 from below, so that the connecting rod 12 drives the upper end of the insertion rod 16 to rise synchronously until the insertion rod 16 contacts the lower end surface of the inner mold 22. At this time, as the electric push rod 13 pushes the connecting rod 12 to continue to rise, the insertion rod 16 is blocked by the lower end surface of the inner mold 22 and squeezes the support spring 162 into the circular groove 161. Since the bottom of the circular groove 161 is embedded with a pressure sensor 163, that is, when the insertion rod 16 squeezes the support spring 162 into the circular groove 161, the sensor in the circular groove 161 is squeezed. At this time, the pressure sensor 163 transmits an electrical signal to the drive motor 15, so that the drive motor 15 is operated, so that the drive motor 15 can drive the transmission gear 151 to rotate, so that the transmission gear 151 drives the gear ring 14 to rotate through the transmission belt 152, so that The gear ring 14 drives the connecting rod 12 connected thereto for sliding connection to rotate synchronously, so that the connecting rod 12 can drive the insert rod 16 to rotate at the lower end of the inner mold 22. Since the upper end of the insert rod 16 is set as a semicircle, the insert rod 16 and the lower end surface of the inner mold 22 are in point contact, thereby reducing the friction between the insert rod 16 and the lower end surface of the inner mold 22. When the driving motor 15 drives the connecting rod 12 to rotate, the connecting rod 12 drives the insert rod 16 to rotate at the lower end surface of the inner mold 22. The friction between the lower end surfaces is reduced, and the wear between the insertion rod 16 and the lower end surface of the inner mold 22 is reduced, thereby increasing the service life of the insertion rod 16 and the inner mold 22. When the insertion rod 16 rotates to the slot, the insertion rod 16 is pushed out of the circular groove 161 and inserted into the slot by the restoring force of the fixed spring 232. At this time, the fixed spring 232 recovers and no longer applies an extrusion force to the pressure sensor 163. At this time, the pressure sensor 163 no longer transmits an electrical signal to the drive motor 15, and the drive motor 15 stops rotating.

[0040] Then continue to control the electric push rod 13 to push the connecting rod 12 close to the outer mold 21 until the connecting rod 12 contacts the sealing rod 241, so that the sealing rod 241 is pushed by the connecting rod 12 and enters the sealing groove 24. In the initial state, the sealing groove 24 is filled with hydraulic oil, and the fixing rod 23 extends out of the fixing groove 231 and is inserted into the card groove 233 on the outer wall of the inner mold 22, so that the hydraulic oil in the sealing groove 24 will be squeezed by the sealing rod 241 and enter the fixing groove 231, so that the hydraulic oil entering the fixing groove 231 will push the fixing rod 23 to squeeze the fixing spring 232 deep into the fixing groove 231. At this time, the outer mold 21 and the inner mold 22 are no longer fixed by the fixing rod 23.

[0041] When the glass product is being blown, the user directly controls the driving motor 15 to operate, so that the driving motor 15 can drive the connecting rod 12 to rotate, so that the connecting rod 12 drives the inner mold 22 to rotate through the insert rod 16, so that when the inner mold 22 rotates, the inner mold 22 contacts the blown cone bubble through the heat-resistant plate 221 on the inner wall, so that the heat-resistant plate 221 directly contacts the high-temperature liquid glass and generates friction. Since the cone bubble is high-temperature liquid glass and has a certain viscosity, this friction will be applied to the outer wall of the glass, which will drive the glass to flow along the rotation direction of the heat-resistant plate 221. In the process of glass blowing, the seam gap is where the glass flow is easily interrupted. The friction force generated by the rotation of the heat-resisting plate 221 pushes the glass to continue to flow, which can make the flow of the glass in the entire inner mold 22 more coherent, avoid the discontinuity caused by flow interruption, greatly reduce the obviousness of the seam line, and make the structure of the glass at the seam more continuous and uniform. On the one hand, it can make the surface of the glass product smoother and continuous, and the overall appearance more uniform, so that the glass product can better show its transparent and pure characteristics, giving people a delicate and beautiful visual experience. On the other hand, it can improve the overall strength of the glass product and reduce the risk of breakage, thereby further enhancing the practicality of the present invention.

[0042] After subsequent annealing, grinding, polishing and other processing steps, the blown glass bottle products can be used to store alcoholic beverages, special beverages or medicines. However, some medicines are extremely demanding on storage conditions. Temperature and light changes may affect their chemical stability and efficacy. Therefore, it is necessary to coat the surface of the glass bottle products with one or more layers of metal or compound films. This film has a high transmittance to visible light and a high reflectivity to infrared rays (especially mid- and far-infrared rays). Ultraviolet rays and oxygen will accelerate the deterioration and oxidation of substances in the bottle (such as food, medicine, etc.), affecting their shelf life and quality. Coated glass bottles can effectively delay this process and reduce waste caused by deterioration of contents. For example, it reduces the early discard of food due to deterioration, indirectly saving the energy required to produce these foods. Therefore, coated glass bottles are also called energy-saving glass bottles.

[0043] As an embodiment of the present invention, a pressure stabilizing port 25 is provided on the outer wall of the outer mold 21 ; a threaded rod 251 is connected to the inner thread of the pressure stabilizing port 25 ; and the pressure stabilizing port 25 is connected to the fixing groove 231 via an air passage 252 .

[0044] As an embodiment of the present invention, a strip groove 17 is provided at the upper end of the body 1; the outer shell is slidably connected in the strip groove 17; a spring hose 171 is provided in the strip groove 17; an air hole 211 is provided on the inner wall of the outer mold 21; a through hole 172 is provided at the lower end of the strip groove 17; one end of the spring hose 171 is connected to the air hole 211, and the other end passes through the through hole 172 to be connected to the external fan.

[0045] As an embodiment of the present invention, a corrugated plate 173 is provided above the strip groove 17 and is slidably connected to the machine body 1 ; and a bellows 111 is sleeved on the surface of the hydraulic push rod 11 .

[0046] As an embodiment of the present invention, a guide groove 212 communicating with the air hole 211 is formed on the inner wall of the outer mold 21; the guide groove 212 is arranged in a spiral shape.

[0047] During operation, since the shaping mold 2 is a key tool for forming glass bottles, the shape of its inner cavity directly determines the final shape of the glass bottle. When it is necessary to blow glass bottle products of different shapes, the user needs to replace a different shaping mold 2, which requires the user to disassemble and replace the shaping mold 2. Because the shaping mold 2 is usually closely connected to the equipment, it is necessary to avoid not only damaging the mold itself but also damaging the related equipment parts during disassembly, making the entire disassembly and replacement process of the shaping mold 2 relatively cumbersome and complicated. In addition, the shaping mold 2 is heavy as a whole, and both transportation and disassembly require a lot of manpower and time, which inevitably reduces the production efficiency of the glass bottles.

[0048] To this end, the present invention provides a threaded rod 251. When the inner mold 22 needs to be replaced, the user rotates the threaded rod 251 to enter the pressure-stabilizing port 25, so that the hydraulic oil in the pressure-stabilizing port 25 is squeezed into the fixed groove 231 through the air channel 252, so that the hydraulic oil entering the fixed groove 231 can push the fixed rod 23 to extend out of the slot 233 and enter the fixed groove 231, so that the outer mold 21 is separated from the inner mold 22. At this time, the user only needs to rotate the inner mold 22 to remove the inner mold 22 and replace the required inner mold 22, so that there is no need to disassemble and replace the entire shaping mold 2, which greatly reduces the difficulty of disassembling and replacing the shaping mold 2. It not only reduces the labor intensity of the operator, but also improves the efficiency of disassembling and replacing the shaping mold 2, thereby improving the production efficiency of the glass bottle.

[0049] In the initial state, the two adjacent outer molds 21 are in a state of being away from each other under the pull of the hydraulic push rod 11. At this time, the connecting rod 12 does not contact the sealing rod 241, so the sealing rod 241 cannot push the fixing rod 23 into the fixing groove 231, that is, the outer mold 21 and the inner mold 22 are in a connected state. Therefore, it is difficult for the user to remove and replace the inner mold 22 alone. Therefore, the present invention provides a pressure stabilizing port 25. When the inner mold 22 needs to be replaced, the user only needs to rotate the threaded rod 251 so that the threaded rod 251 spirals into the pressure stabilizing port 25, so that the hydraulic oil in the pressure stabilizing port 25 is pushed by the threaded rod 251 and flows into the fixing groove 231 through the air channel 252, so that the hydraulic oil flowing into the fixing groove 231 can push the fixing rod 23 to squeeze the fixing spring 232 and enter the fixing groove 231, so that the fixing rod 23 can be replaced. The fixing rod 23 of the fixed groove 231 extends out of the card slot 233, so that the fixing rod 23 is no longer connected to the outer mold 21 and the inner mold 22, so that the outer mold 21 is separated from the inner mold 22. At this time, the user only needs to rotate the inner mold 22 to separate the inner mold 22 from the outer mold 21. Then the user rotates the new inner mold 22 to connect it with the outer mold 21, and then rotates the replaced inner mold 22, so that the replaced inner mold 22 drives the card slot 233 to rotate to the fixed groove 231. At this time, the threaded rod 251 is rotated in the opposite direction so that the threaded rod 251 can be spirally extended out of the pressure stabilizing port 25. At this time, the fixed spring 232 in the fixed groove 231 pushes the fixing rod 23 to squeeze the hydraulic oil back to the pressure stabilizing port 25 through the air channel 252. At this time, the reset fixing rod 23 is reinserted into the card slot 233, so that the replaced outer mold 21 and the inner mold 22 are connected.

[0050] When the driving motor 15 drives the inner mold 22 to rotate through the connecting rod 12, friction contact will occur between the inner mold 22 and the outer mold 21, so that the inner mold 22 and the outer mold 21 will wear due to rotation, thereby reducing the service life of the inner mold 22 and the outer mold 21. To this end, the present invention provides a spring hose 171. Since the spring hose 171 is connected to the external fan, the user controls the operation of the external fan so that the fan conveys air through the spring hose 171 and flows into the air hole 211, so that the air entering the air hole 211 is transported to between the outer mold 21 and the inner mold 22, so that the air flowing between the inner mold 22 and the outer mold 21 can form a thin gas film between the inner mold 22 and the outer mold 21. This gas film is like an isolation layer, which separates the surfaces of the inner mold 22 and the outer mold 21, reducing the direct contact area between them, so that when the inner mold 22 is rotated, the original The friction on the surface of the inner mold 22 and the outer mold 21 is transformed into friction between the inner mold 22 and the gas film, and between the gas film and the outer mold 21. Since the viscosity of the gas is much smaller than the surface friction of the solid material, this change in friction form can significantly reduce the friction between the inner mold 22 and the outer mold 21, thereby reducing the wear between the inner mold 22 and the outer mold 21, and thus improving the service life of the inner mold 22 and the outer mold 21. Since air is a poor conductor of heat and its thermal conductivity is relatively low, heat needs to pass through this layer of air film to be transferred from the inner mold 22 to the outer mold 21. The existence of the air film increases the resistance to heat transfer, making heat transfer more difficult, thereby reducing the heat transferred to the outer mold 21, greatly reducing the temperature of the outer mold 21, slowing down the thermal aging rate of the hydraulic oil in the outer mold 21, and thus improving the service life of the hydraulic oil, so that the actual application effect of the present invention is effectively improved.

[0051] In addition, the purpose of setting the strip groove 17 is to install the spring hose 171, and the setting of the corrugated plate 173 is to protect the spring hose 171 in the strip groove 17 to avoid the spring hose 171 from being exposed to the upper end of the body 1, so as to prevent the high-temperature liquid glass clamped at the blowing head from dripping on the spring hose 171 due to operational errors, causing the spring hose 171 to be damaged by heat, that is, protecting the spring hose 171, improving the service life of the spring hose 171, and ensuring that the present invention can operate normally and stably. Similarly, the setting of the bellows 111 is to enable the bellows 111 to protect the hydraulic push rod 11 to avoid The high-temperature liquid glass clamped at the blowing head is prevented from dripping onto the hydraulic push rod 11, which prevents the hydraulic push rod 11 from being damaged by heat, thereby effectively improving the practicality of the present invention. The corrugated plate 173 and the bellows 111 are both made of silicone rubber material, so that the corrugated plate 173 and the bellows 111 made of silicone rubber material have good thermal stability and high-temperature resistance. This high-temperature resistance enables it to resist the high-temperature influence of liquid glass to a certain extent, and prevents the corrugated plate 173 and the bellows 111 from being burned through, so as to ensure that the bellows 111 and the corrugated plate 173 can effectively protect the spring hose 171 and the hydraulic push rod 11.

[0052] By setting a guide groove 212 connected to the air hole 211 on the inner wall of the outer mold 21, and when the two outer molds 21 are closed, the guide grooves 212 on the inner walls of the two outer molds 21 are connected and spiral. When the external fan delivers air to the air hole 211 through the spring hose 171 of one side of the outer mold 21, the air delivered to the space between the outer mold 21 and the inner mold 22 through the air hole 211 can flow around the inner mold 22 under the guidance of the guide groove 212, and flow from the other end of the guide groove 212 to the air hole 211 of the other outer mold 21, and finally flow out from the spring hose 171 connected to the other outer mold 21. The air rotating around the outer wall of the inner mold 22 will generate a certain rotational thrust on the outer wall of the inner mold 22. When the air flows along the spiral guide groove 212, its rotation direction is consistent with the rotation direction of the inner mold 22, just like applying an additional boost to the inner mold 22. Although the thrust is relatively small, it can effectively reduce the burden on the driving equipment during long-term rotation and improve the efficiency of the rotation of the inner mold 22. In addition, this rotational thrust can also help the inner mold 22 maintain a stable rotation state. This is because in actual production, the inner mold 22 is easily disturbed by various factors such as equipment vibration and uneven distribution of glass liquid, which causes the rotation of the inner mold 22 to fluctuate. Therefore, the rotational thrust generated by the air guided by the guide groove 212 can play a certain balancing and buffering role against these interferences, making the rotation of the inner mold 22 more stable, reducing shaking and deviation, so as to ensure that the flow of the blown glass inside the entire inner mold 22 is more stable and coherent, avoiding the discontinuity caused by flow interruption, and greatly reducing the obvious degree of the seam line of the blown glass product, so that the strength and overall visual effect of the glass product are improved.
