Description

Technical Field

[0001] This utility model relates to the field of glass insulator production technology, and in particular to a durable mold cup holder for glass insulator production. Background Technology

[0002] In the production process of glass insulators, the mold holder is one of the key components in the molding of glass products, and its performance directly affects the product quality and production efficiency. Traditional mold holders are mostly designed using a single material and a single cooling method, and generally suffer from the following problems:

[0003] 1. Low cooling efficiency: Traditional cooling methods usually rely on natural cooling or simple water cooling systems, which cannot quickly and effectively dissipate the large amount of heat generated after the high-temperature molten glass (about 1400°C) is injected, resulting in uneven temperature distribution of the mold bowl seat.

[0004] 2. Internal stress caused by temperature difference: Due to the uneven volume shrinkage of glass material during cooling, the temperature difference between the bottom of the mold cup seat and the side wall is large, which can easily form micro-cracks on the surface of the glass insulator, affecting its mechanical strength and electrical insulation performance.

[0005] To address these issues, we propose a durable mold cup holder for glass insulator production. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a durable mold cup holder for glass insulator production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A durable mold cup holder for glass insulator production includes a conical fixing base with a groove inside. A gas supply structure is connected to one side of the lower end of the conical fixing base. An arc-shaped guide plate is fixed on the inner circumferential side wall of the conical fixing base. A first connecting ring and a second connecting ring are engaged in the groove. The first and second connecting rings are connected by four connecting pipes. A coolant delivery pipe is connected to one side of the first connecting ring, and a coolant return pipe is connected to one side of the second connecting ring. The coolant delivery pipe and the coolant return pipe penetrate the side wall of the conical fixing base and extend to one side of the conical fixing base. The mold cup holder body is engaged in the first and second connecting rings.

[0009] Preferably, the gas supply structure includes a gas supply pipe connected to one side of the lower end of the conical fixed seat, one end of the gas supply pipe is connected to a conical conveying hood, and one end of the conical conveying hood is connected to a blower.

[0010] Preferably, one end of the blower is connected to an air inlet pipe, and a filter screen is installed on the air inlet pipe.

[0011] Preferably, the conical fixing seat has an internal interlayer containing a phase-changing material.

[0012] Preferably, the conical fixing base is made of high-strength stainless steel.

[0013] Preferably, the mold bowl body is made of silicon carbide ceramic matrix composite material.

[0014] In this invention, during cooling:

[0015] 1. Coolant circulation system (main cooling)

[0016] The coolant enters the first connecting ring through the coolant delivery pipe, flows to the second connecting ring through the connecting pipe, and is then discharged through the coolant return pipe. The coolant forms a closed loop in the annular structure and flows around the mold cup body to achieve continuous cooling of the high-temperature glass melt, improve cooling efficiency, reduce the temperature gradient of the mold cup body, and avoid material fatigue and structural deformation caused by local overheating.

[0017] 2. Auxiliary air cooling system (secondary cooling)

[0018] The blower draws in outside air through the air inlet pipe, which is then filtered by the filter screen and enters the conical conveying hood. The gas is then transported to the slot area through the air delivery pipe. Combined with the arc-shaped guide plate, it achieves directional airflow cooling of the lower part of the mold bowl seat. The gas cooling and liquid cooling work together to form a composite cooling mechanism, which improves the overall heat dissipation efficiency. The arc-shaped guide plate optimizes the airflow path, avoids turbulence and dead corners, and ensures uniform cooling.

[0019] 3. Sandwich structure and phase change material (thermal buffer)

[0020] The interlayer, located inside the conical fixing base, is used to fill a material with high heat capacity and phase change heat absorption capacity (paraffin-based or salt-based phase change materials). When the molten glass is injected, the phase change material absorbs heat and undergoes a phase change (solid to liquid), effectively buffering thermal shock, mitigating the impact of sudden temperature rise on the mold cup body, extending service life, improving system thermal stability, and reducing stress problems caused by temperature fluctuations. The mold cup body is made of silicon carbide ceramic matrix composite material, which has excellent properties such as high temperature resistance, oxidation resistance, and thermal shock resistance. The silicon carbide composite material can still maintain structural stability at high temperatures, reducing crack formation. The conical fixing base is made of high-strength stainless steel, ensuring that the overall structure does not deform or oxidize under high temperature and high pressure environments.

[0021] This utility model has the following advantages:

[0022] 1. Through the design of an efficient cooling system, the overall temperature field of the mold cup seat is more uniform, avoiding problems such as stress cracks and deformation caused by uneven cooling of glass products, thereby improving the yield and consistency of glass insulators;

[0023] 2. The composite cooling system (liquid cooling plus gas cooling plus phase change material) effectively reduces the thermal fatigue of the mold cup seat. Combined with the excellent performance of silicon carbide ceramic matrix composite material, it significantly extends the service life of the equipment and reduces the frequency and cost of maintenance.

[0024] 3. The mold cup holder is not only suitable for the production of glass insulators, but can also be extended to other high-temperature forming processes, such as the manufacturing fields of ceramics, composite materials, and special glass, and has a wide range of engineering application prospects;

[0025] In summary, this utility model, through structural optimization and material upgrades, constructs a highly efficient, stable, and durable cooling system, effectively solving the problems of low cooling efficiency, large temperature difference, and easy cracking of traditional mold cup seats. It improves the production quality and equipment life of glass insulators, significantly extends the service life of equipment, and reduces maintenance frequency and costs. It is not only suitable for the production of glass insulators, but can also be extended to other high-temperature forming process manufacturing fields. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figure 1-5 A durable mold cup holder for glass insulator production includes a conical fixing seat 1. The conical fixing seat 1 is made of high-strength stainless steel, which has excellent tensile strength, corrosion resistance and high-temperature oxidation resistance, and is suitable for high-temperature and high-pressure production environments.

[0034] The conical fixing seat 1 is provided with a slot 14. A gas supply structure is connected to one side of the lower end of the conical fixing seat 1. An arc-shaped guide plate 13 is fixed on the inner wall of the conical fixing seat 1. The arc-shaped guide plate 13 is set on the inner wall of the conical fixing seat to guide the airflow along a specific path, enhance the uniformity of the airflow, avoid local overheating or cooling dead corners, and improve the cooling efficiency.

[0035] The first connecting ring 10 and the second connecting ring 12 are engaged in the slot 14. The first connecting ring 10 and the second connecting ring 12 are connected by four connecting pipes 11. The two annular structures are connected by four connecting pipes 11 to form a closed-loop cooling channel, which is arranged around the mold bowl body 2 to achieve uniform cooling.

[0036] The first connecting ring 10 is connected to a coolant delivery pipe 3 on one side, and the second connecting ring 12 is connected to a coolant return pipe 4 on one side. The coolant delivery pipe 3 and the coolant return pipe 4 are respectively connected to the first and second connecting rings to form a coolant circulation path, which facilitates efficient heat exchange.

[0037] Coolant delivery pipe 3 and coolant return pipe 4 pass through the side wall of conical fixed seat 1 and extend to one side of conical fixed seat 1. The first connecting ring 10 and the second connecting ring 12 are jointly engaged with mold cup seat body 2. The mold cup seat body 2 is made of silicon carbide ceramic matrix composite material, which has excellent properties such as high temperature resistance, oxidation resistance and thermal shock resistance. The silicon carbide composite material can still maintain structural stability at high temperature and reduce crack generation.

[0038] The gas delivery structure includes a gas delivery pipe 5 connected to one side of the lower end of the conical fixed base 1. One end of the gas delivery pipe 5 is connected to a conical conveying hood 6, and one end of the conical conveying hood 6 is connected to a blower 7. The gas delivery pipe 5 guides the gas to the conical conveying hood. Its conical design helps to concentrate the airflow and improve cooling efficiency.

[0039] One end of the blower 7 is connected to the air inlet pipe 8, and the air inlet pipe 8 is equipped with a filter screen 9. The blower 7 provides continuous and stable airflow power, and the air inlet pipe is responsible for introducing external air into the system. The filter screen 9 is used to filter impurities in the air and prevent dust from entering the cooling system, which would affect the stability of equipment operation and the cleanliness of the mold bowl seat.

[0040] The conical fixing seat 1 has an internal interlayer 15, which contains a phase change material. The conical fixing seat 1 is made of high-strength stainless steel, and the mold bowl seat body 2 is made of silicon carbide ceramic matrix composite material. The interlayer structure 15 is located inside the conical fixing seat and is used to fill the material with high heat capacity and phase change heat absorption capacity, effectively absorbing instantaneous thermal shock and mitigating the impact of sudden temperature changes on the system.

[0041] In this invention, during cooling:

[0042] 1. Coolant circulation system (main cooling)

[0043] The coolant enters the first connecting ring 10 through the coolant delivery pipe 3, flows to the second connecting ring 12 through the connecting pipe 11, and is then discharged through the coolant return pipe 4. The coolant forms a closed loop in the annular structure and flows around the mold cup body 2, thereby achieving continuous cooling of the high-temperature glass melt, improving cooling efficiency, reducing the temperature gradient of the mold cup body, and avoiding material fatigue and structural deformation caused by local overheating.

[0044] 2. Auxiliary air cooling system (secondary cooling)

[0045] Blower 7 draws in external air through intake pipe 8, and after being filtered by filter screen 9, it enters conical conveyor hood 6. The gas is delivered to the slot 14 area through air delivery pipe 5. Combined with arc-shaped guide plate 13, it achieves directional airflow cooling of the lower part of the mold bowl seat. Gas cooling and liquid cooling work together to form a composite cooling mechanism, which improves the overall heat dissipation efficiency. The arc-shaped guide plate optimizes the airflow path, avoids turbulence and dead corners, and ensures uniform cooling.

[0046] 3. Sandwich structure and phase change material (thermal buffer)

[0047] The interlayer is located inside the conical fixing seat 1 and is used to fill the material with high heat capacity and phase change heat absorption capacity (paraffin or salt phase change material). When the molten glass is injected, the phase change material absorbs heat and undergoes a phase change (solid to liquid), which effectively buffers thermal shock, reduces the impact of sudden temperature rise on the mold cup body, extends service life, improves system thermal stability, and reduces stress problems caused by temperature fluctuations. The mold cup body 2 is made of silicon carbide ceramic matrix composite material, which has excellent properties such as high temperature resistance, oxidation resistance, and thermal shock resistance. The silicon carbide composite material can still maintain structural stability at high temperatures and reduce crack generation. The conical fixing seat 1 is made of high-strength stainless steel to ensure that the overall structure does not deform or oxidize under high temperature and high pressure environments.
