Description

Technical Field

[0001] This utility model belongs to the field of glass hot bending mold technology, and more specifically, it relates to a temperature measuring structure for a glass hot bending mold. Background Technology

[0002] Temperature control and measurement are crucial in the production of hot-bent glass. The hot-bending process mainly includes preheating, forming, annealing, and cooling. During preheating, the glass needs to be heated continuously or slowly to ensure uniform temperature within the furnace. When the glass reaches its softening point, it will begin to deform under its own weight or external pressure until it conforms to the curvature of the mold. Operators need to constantly observe the glass forming process within the furnace and control the number, area, and duration of the heating lamps. Precise temperature control during hot bending is essential to prevent glass breakage and ensure product quality. Currently, temperature measurement in glass hot bending processes mainly relies on thermocouples contacting the mold or infrared devices. However, existing methods only provide the surface temperature of the mold, which differs significantly from the actual glass temperature, thus failing to accurately and effectively monitor the actual temperature.

[0003] Existing technology includes a device for heating a glass mold with uniform temperature rise, published under publication number CN116678207A. This device comprises a heating chamber with hinged sealing doors on both the front and back. A reciprocating mechanism is installed inside the heating chamber, with a heating tube on one side and a rotating mechanism on the right side. Sealing mechanisms are located on both the front and back of the heating chamber, and a fan is installed on one side of the reciprocating mechanism. This invention offers strong practicality and uniform temperature rise. By incorporating a reciprocating mechanism, a second motor is activated, causing its second output shaft to drive a drive gear. This drive gear then sequentially drives a driven gear, a worm gear, a worm wheel, and a support shaft, allowing the glass mold placed on top of the support platform to rotate and be heated. This further improves the uniformity of heating, enabling the glass mold to be heated from all directions, facilitating further processing of the glass.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a simple glass hot bending mold temperature measurement structure that, after the glass is hot-bent, can accurately measure and obtain the actual temperature of the glass surface by switching the temperature measuring mold, and can compare it with the temperature of the heating plate to obtain the temperature difference value. This allows for reliable monitoring of the temperature during the glass hot bending process, preventing excessive temperature, and adjusting the temperature of the heating plate according to the actual temperature of the glass to ensure that the glass is hot-bent at a suitable temperature.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model relates to a temperature measuring structure for a glass hot bending mold. The upper mold includes a forming upper mold and a temperature measuring upper mold. The temperature measuring upper mold includes a temperature measuring upper mold body and a temperature measuring upper mold forming protrusion. The temperature measuring upper mold forming protrusion includes a temperature measuring upper mold convex surface. The upper mold is provided with multiple temperature measuring holes, which penetrate the temperature measuring upper mold body and the temperature measuring upper mold forming protrusion. A temperature measuring thermocouple is installed in the temperature measuring hole, and the temperature measuring thermocouple extends to a position flush with the temperature measuring upper mold convex surface.

[0008] The upper forming mold includes an upper forming mold body and an upper forming mold forming protrusion, the upper forming mold forming protrusion including an upper forming mold forming convex surface.

[0009] The temperature measuring structure of the glass hot bending mold also includes a lower mold, which includes a lower mold body and a lower mold forming cavity, and the forming cavity includes a forming concave surface.

[0010] The temperature measuring upper mold forming protrusion is configured to engage with the lower mold forming cavity of the lower mold.

[0011] The upper forming mold of the upper forming mold is configured to be able to engage with the lower forming cavity of the lower mold.

[0012] The temperature-measuring thermocouple is connected to the temperature-measuring and display device via wires.

[0013] The upper temperature measuring mold is configured to be made of high-temperature resistant materials such as graphite, tungsten steel, silicon carbide, or ceramic fiber; the lower mold is configured to be made of high-temperature resistant materials such as graphite, tungsten steel, silicon carbide, or ceramic fiber.

[0014] The upper surface of the temperature measuring mold body is either the contact surface of the heating plate or the contact surface of the IR lamp tube.

[0015] The lower surface of the lower mold body is the contact surface of the heating plate.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The temperature measuring structure of the glass hot bending mold described in this utility model comprises two types of upper molds: a forming upper mold and a temperature measuring upper mold. The two upper molds have the same structure, the difference being that the temperature measuring upper mold has temperature measuring holes. Specifically, the temperature measuring upper mold includes a temperature measuring upper mold body and a temperature measuring upper mold forming protrusion, which are integral structures. The temperature measuring upper mold forming protrusion is used to cooperate with the lower mold to form a mold cavity for measuring the temperature of the glass. Multiple temperature measuring holes are provided on the upper mold, penetrating both the temperature measuring upper mold body and the temperature measuring upper mold forming protrusion. Temperature measuring thermocouples are installed within these temperature measuring holes, extending to a position flush with the convex surface of the temperature measuring upper mold. Specifically, during glass hot bending, the forming upper mold and the lower mold cooperate to form a mold cavity, completing the glass hot bending process. After the glass is hot-bent, the upper mold is immediately switched, and a temperature-measuring upper mold and lower mold are used in conjunction. The temperature-measuring thermocouple in the temperature-measuring hole of the upper mold contacts the glass surface to measure the actual temperature of the glass surface. Different temperature-measuring thermocouples obtain the actual temperature at different locations. Thermocouples are also installed on the heating plate on the body of the temperature-measuring upper mold to obtain the actual temperature at the heating plate location. The temperature of the heating plate of the forming upper mold is the same as the temperature of the heating plate of the temperature-measuring upper mold, which allows us to obtain the temperature difference between the heating plate and the glass surface. Since the temperature of the heating plate and the temperature of the glass surface are directly proportional, the temperature of the heating plate can be adjusted according to the actual temperature requirements of the glass surface, thereby changing the temperature of the glass surface.

[0025] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0026] As attached Figure 1 -Appendix Figure 5As shown, this utility model discloses a temperature measuring structure for a glass hot bending mold. The upper mold includes a forming upper mold and a temperature measuring upper mold. The temperature measuring upper mold includes a temperature measuring upper mold body 1 and a temperature measuring upper mold forming protrusion 2. The temperature measuring upper mold forming protrusion 2 includes a temperature measuring upper mold convex surface 3. Multiple temperature measuring holes 4 are provided on the upper mold, penetrating the temperature measuring upper mold body 1 and the temperature measuring upper mold forming protrusion 2. A temperature measuring thermocouple 5 is installed within each temperature measuring hole 4, extending to a position flush with the temperature measuring upper mold convex surface 3. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In the structural design, two types of upper molds are manufactured: a forming upper mold and a temperature measuring upper mold. The two upper molds have the same structure, the difference being that the temperature measuring upper mold has temperature measuring holes 4. Specifically, the temperature measuring upper mold includes a temperature measuring upper mold body 1 and a temperature measuring upper mold forming protrusion 2, which are an integral structure. The temperature measuring upper mold forming protrusion 2 is used to cooperate with the lower mold to form a mold cavity for measuring the glass temperature. Multiple temperature measuring holes 4 are provided on the upper mold, penetrating both the temperature measuring upper mold body 1 and the temperature measuring upper mold forming protrusion 2. This allows for the placement of temperature measuring thermocouples 5 within the temperature measuring holes 4, extending to a position flush with the convex surface 3 of the temperature measuring upper mold. Specifically, during glass hot bending, the forming upper mold and the lower mold cooperate to form a mold cavity, completing the glass hot bending process. After the glass is hot-bent, the upper mold is immediately switched. The forming upper mold separates from the lower mold, and a temperature-measuring upper mold works in conjunction with the lower mold. Thermocouples inside the temperature-measuring upper mold contact the glass surface to measure its actual temperature. Different thermocouples provide the temperature at different locations. Thermocouples are also installed on the heating plate of the temperature-measuring upper mold body to obtain the actual temperature at the heating plate location. The temperature of the heating plate in the forming upper mold and the temperature-measuring upper mold are the same, allowing the measurement of the temperature difference between the heating plate and the glass surface. Since the temperature of the heating plate and the glass surface are directly proportional, the temperature of the heating plate is adjusted according to the actual temperature requirements of the glass surface, thereby changing the glass surface temperature. The temperature measuring structure of the glass hot bending mold described in this utility model is simple in structure. After the glass is hot bent, the actual temperature of the glass surface can be accurately measured by switching the temperature measuring mold. The temperature can be compared with the temperature of the heating plate to obtain the temperature difference value. This allows for reliable monitoring of the temperature during the glass hot bending process, avoiding excessive temperature. The temperature of the heating plate can also be adjusted according to the actual temperature of the glass to ensure that the glass is hot bent at a suitable temperature.

[0027] The upper forming mold includes an upper forming mold body 6 and an upper forming mold forming protrusion 7, the upper forming mold forming protrusion 7 including an upper forming mold forming convex surface 8. With this structure, the upper forming mold cooperates with the lower mold to complete the hot bending forming of the glass, resulting in a finished glass product.

[0028] The temperature measuring structure of the glass hot bending mold also includes a lower mold, which includes a lower mold body 9 and a lower mold forming cavity 10, and the forming cavity 10 includes a forming concave surface 11. In the above structure, the lower mold forming cavity 10 of the lower mold is matched with the upper mold forming protrusion of the upper mold to ensure that when the upper mold and the lower mold are in contact, force can be reliably applied to form curved glass.

[0029] The upper temperature measuring mold forming protrusion 2 is configured to engage with the lower temperature measuring mold forming cavity 10. With this configuration, when the upper and lower temperature measuring molds are engaged, the temperature measuring thermocouple contacts the glass surface, thus achieving glass surface temperature measurement.

[0030] The upper forming mold's forming protrusion 7 is configured to engage with the lower forming cavity 10 of the lower mold. With this configuration, when the upper and lower molds are engaged, the glass material can be reliably hot-bent to form the finished glass product.

[0031] The temperature-measuring thermocouple 5 is connected to the temperature-measuring display device 13 via a wire 12. In this configuration, the temperature-measuring display device 13 collects the actual temperature data obtained from the measurement and displays the temperature data on the device's screen, facilitating real-time observation and monitoring of the data by on-site personnel.

[0032] The upper temperature measuring mold is constructed from high-temperature resistant materials such as graphite, tungsten steel, silicon carbide, or ceramic fiber; the lower mold is also constructed from high-temperature resistant materials such as graphite, tungsten steel, silicon carbide, or ceramic fiber. Both the upper and lower molds exhibit good high-temperature resistance.

[0033] The upper surface of the temperature measuring upper mold body 1 is the contact surface of the heating plate or the contact surface of the IR lamp. The lower surface of the lower mold body 9 is the contact surface of the heating plate. In this structure, the upper mold is heated by the heating plate or the IR lamp, and the lower mold is heated by the heating plate.

[0034] The temperature measuring structure of the glass hot bending mold described in this utility model comprises two types of upper molds: a forming upper mold and a temperature measuring upper mold. The two upper molds have the same structure, the difference being that the temperature measuring upper mold has temperature measuring holes 4. Specifically, the temperature measuring upper mold includes a temperature measuring upper mold body 1 and a temperature measuring upper mold forming protrusion 2, which are integrally formed. The temperature measuring upper mold forming protrusion 2 is used to cooperate with the lower mold to form a mold cavity for measuring the glass temperature. Multiple temperature measuring holes 4 are provided on the upper mold, penetrating both the temperature measuring upper mold body 1 and the temperature measuring upper mold forming protrusion 2. This allows for the placement of temperature measuring thermocouples 5 within the temperature measuring holes 4, extending to a position flush with the convex surface 3 of the temperature measuring upper mold. In detail, during glass hot bending, the forming upper mold and the lower mold cooperate to form a mold cavity, completing the glass hot bending process. After the glass is hot-bent, the upper mold is immediately switched. The forming upper mold separates from the lower mold, and a temperature-measuring upper mold works in conjunction with the lower mold. Thermocouples in the temperature-measuring upper mold contact the glass surface to measure its actual temperature. Different thermocouples provide the temperature at different locations. Thermocouples are also installed on the heating plate of the temperature-measuring upper mold body to obtain the actual temperature at the heating plate location. The temperature of the heating plate in the forming upper mold and the temperature-measuring upper mold are the same, thus providing the temperature difference between the heating plate and the glass surface. Since the temperature of the heating plate and the glass surface are directly proportional, the temperature of the heating plate can be adjusted according to the actual temperature requirements of the glass surface, thereby changing the glass surface temperature.
