Description

Technical Field

[0001] This utility model belongs to the field of glass manufacturing technology, and more specifically, it relates to a heating module structure for a glass hot pressing mold. Background Technology

[0002] In today's industrial production, hot bending plays a crucial role, widely used in manufacturing parts with complex shapes. Its application is particularly prominent in the aerospace, automotive, and construction industries. To ensure that parts manufactured through hot bending meet precise dimensional and high-quality standards, meticulous adjustment and improvement of the hot bending process are essential. In the field of glass manufacturing, the temperature of the mold's heating surface has a significant impact on the quality of glass products.

[0003] Existing technology includes a patent titled "Hot Press Mold, Method for Hot Pressing Curved Glass and Its Application," with publication number CN110143752A. This technology proposes a hot press mold, a method for hot pressing curved glass, and its application. The hot press mold includes: a punch with a protrusion comprising a first planar portion and a first curved surface portion; and a die with a recessed portion that mates with the protrusion, comprising a second planar portion and a second curved surface portion; wherein the first curved surface portion has multiple vent holes. The hot press mold proposed in this application has multiple vent holes on the curved surface portion of the protrusion of the punch. This allows high-pressure gas to be injected from the punch during the hot pressing process of flat glass, causing the softened glass to adhere to the surface of the die, thus facilitating the demolding of large-angle curved glass. However, this technology does not address the technical problem and solution of this application. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model relates to a heating module structure for a glass hot pressing mold, including a mold cavity, with multiple heating modules arranged near the mold cavity. Each heating module forms a mold heating area assembly, and multiple mold heating area assemblies form a mold heating area. Different mold heating area assemblies have structures with the same or different temperatures, and the heating module forming each mold heating area assembly is an electric heater.

[0007] The mold heating area is a grid-type temperature control structure, which includes multiple square mold heating area components, with adjacent mold heating area components arranged in close contact.

[0008] The mold heating area is a ring-shaped temperature control structure, which includes an inner ring mold heating area component and one or more outer ring mold heating area components. The inner ring mold heating area component is located at the center of the mold heating area, and multiple outer ring mold heating areas are arranged around the inner ring mold heating area component.

[0009] The mold cavity is located on the upper part of the lower mold, and the heating module is located on the lower part of the lower mold or inside the cavity of the lower mold.

[0013] Each mold heating zone assembly is equipped with one or more electric heaters.

[0014] Each mold heating zone is equipped with a temperature sensor.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] The glass hot pressing mold heating module structure described in this utility model involves adding a heating module to the mold.

[0022] 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:

[0023] As attached Figure 1 -Appendix Figure 3 As shown, this utility model discloses a heating module structure for a glass hot pressing mold, including a mold cavity 1, multiple heating modules 2 arranged near the mold cavity 1, each heating module 2 forming a mold heating area component 3, and multiple mold heating area components 3 forming a mold heating area 4. Different mold heating area components 3 have structures with the same or different temperatures. The heating module 2 forming each mold heating area component 4 is an electric heater. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In the structural design, a mold cavity 1 and a mold protrusion are provided. During glass hot pressing (hot bending), the mold cavity 1 and the mold protrusion are close together to press the glass material together, simultaneously applying temperature to effectively achieve glass hot pressing and form a glass product with a specific shape. The multiple mold heating area components 3 near the mold cavity 1 form the mold heating area 4. The different mold heating area components 3 have structures with the same or different temperatures, achieving precise regional temperature control within the mold cavity 1. This precise temperature management helps avoid unnecessary thermal stress during the forming process, ensuring product quality, ensuring smooth forming, and improving product quality. The glass hot pressing mold heating module structure described in this utility model has a simple structure, can reliably realize glass hot pressing, and can control the temperature of different parts according to the glass requirements, thereby improving the processing accuracy of the glass surface.

[0024] The mold heating area 4 is a grid-type temperature control structure, which includes multiple square mold heating area components 3 arranged in close proximity. In embodiment 1, the mold heating area 4 of the mold cavity 1 is a grid-type temperature control structure. Specifically, it consists of multiple square mold heating area components 3 arranged adjacent to each other. Each square mold heating area component 3 is equipped with an electric heater for individual heating. By controlling the different temperatures of the electric heaters, different heating temperatures are achieved for corresponding areas of different mold heating area components.

[0025] The mold heating area 4 is a ring-shaped temperature control structure, which includes an inner ring mold heating area component 8 and one or more outer ring mold heating area components 9. The inner ring mold heating area component 8 is located at the center of the mold heating area 4, and multiple outer ring mold heating areas 9 are arranged around the inner ring mold heating area component 8. As an embodiment 2, the mold heating area 4 of the mold cavity 1 is a ring-shaped temperature control structure. Specifically, an inner ring mold heating area 8 is set, which is a circular mold heating area component 3. The outer ring mold heating area components 9 are not ring-shaped, but rather partially ring-shaped, that is, two symmetrical C-shaped heating area components are distributed to form an outer ring mold heating area 9. This allows multiple mold heating areas 4 to reliably cover the mold cavity 1. Each mold heating area component 3 is equipped with an electric heater for individual heating. By controlling the different temperatures of different electric heaters, different heating temperatures are achieved for the areas corresponding to different mold heating area components 4.

[0026] The mold cavity 1 is located on the upper part of the lower mold 5, and the heating module 2 is located on the lower part of the lower mold 5 or inside the cavity of the lower mold 5. This structure defines the location of the heating module 2, ensuring reliable heat transfer to the corresponding mold cavity 1. This results in different temperatures in different parts of the mold cavity 1 during glass pressing and molding, meeting the required conditions.

[0027] The glass hot pressing mold heating module structure also includes a mold protrusion 6, which is disposed on the upper mold 7. In this structure, the upper and lower molds cooperate, meaning the mold protrusion and mold cavity work together to form the product. Both the mold cavity 1 of the lower mold 5 and the mold protrusion 6 of the upper mold 7 are made of graphite. Graphite, due to its excellent heat resistance and thermal conductivity, is suitable for high-temperature operations. The mold cavity 1 and mold protrusion 6 meet the heating requirements.

[0028] When the mold heating area 4 is a ring-shaped temperature control structure, each outer ring mold heating area 9 consists of two symmetrical C-shaped heating area component parts 10.

[0029] Each mold heating zone assembly 3 is equipped with one or more electric heaters. With the above structure, electric heaters are installed as needed, thereby enabling each mold heating zone assembly 3 to control its temperature as required, thus transferring the corresponding heat to the corresponding area of ​​the mold cavity 1.

[0030] Each mold heating zone 4 is equipped with a temperature sensor. In the above structure, the temperature sensor in each mold heating zone senses the actual temperature of the corresponding heating zone and provides feedback on the actual temperature. Then, the mold control component reliably adjusts the set temperature range of each mold heating zone according to the temperature requirements, thereby meeting the hot pressing heating requirements of glass of different models and shapes.

[0031] In Example 1, the temperature of the mold heating area in the middle is higher than that of the mold heating area at the edge; in Example 2, the temperature of the inner ring mold heating area is higher than that of the outer ring mold heating area. This is because significant thermal stress changes occur within a range of ±5-50℃ in the 10mm-400mm range. The heating temperature is controlled within the 5-50℃ heating range.

[0032] The glass hot pressing mold heating module structure of this utility model includes a heating module, a mold cavity 1, and a mold protrusion. During glass hot pressing (hot bending), the mold cavity 1 and the mold protrusion are close together to press the glass material together, and temperature is applied simultaneously, effectively achieving glass hot pressing and forming a glass product with a specific shape. Multiple mold heating area components 3 near the mold cavity 1 form a mold heating area 4. Different mold heating area components 3 have structures with the same or different temperatures, achieving precise regional temperature control within the mold cavity 1. This precise temperature management helps avoid unnecessary thermal stress during the forming process, ensuring product quality, ensuring smooth forming, and improving product quality.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
