[0014] The beneficial effects of the utility model are:

[0015] 1. Save costs and improve production accuracy. Sand molds are used instead of the original steel frame molds for glass castings.

[0031] See also Figures 1 to 4The utility model provides a glass processing mold, including a sand mold assembly 1, a supporting steel pipe 2 and a guide rail 3; the sand mold assembly 1 includes a plurality of sand molds 11, and the plurality of sand molds 11 are connected to each other through a mortise and tenon structure; the supporting steel pipe 2 is provided with a plurality of, the plurality of supporting steel pipes 2 are parallel to each other and arranged below the sand mold assembly 1, and the two end frames of the plurality of supporting steel pipes 2 are both arranged on the guide rail 3. Among them, the guide rail 3 is arranged at the ends of the plurality of supporting steel pipes 2, and the plurality of supporting steel pipes 2 are connected through the guide rail 3.

[0032] Specifically, the sand mold assembly 1 is used as a mold assembly for making glass products, and is used to press-mold the glass original piece. During the processing, the glass original piece is pressed onto the sand mold assembly 1 from the side away from the supporting steel pipe 2. The sand mold assembly 1 is made of high-temperature resistant sand mold 11 material. The shape and size of the sand mold 11 can be designed according to specific process requirements and are not limited here. The sand mold 11 is a mold made of raw sand, adhesives and other auxiliary materials in the casting production process. In the specific implementation, the sand mold 11 mold is formed by splicing six sand molds 11 with a rectangular cross-section. The sand mold 11 material has the characteristics of being light and soft, resistant to bending, high in impact strength, low in cost, and easy to process. Compared with the steel frame mold in the prior art, the sand mold 11 mold is used for glass die-casting production with lower cost, higher precision, and significantly improved yield of the finished product. The glass original piece is hyperbolic glass.

[0033] Among them, in a specific implementation, the sand mold 11 used for glass processing molds is formed using 3D printing technology. The traditional sand mold 11 manufacturing usually requires multiple steps such as making molds, preparing sand materials, pouring, and curing, while the use of 3D printing technology can directly convert the digital model into a physical sand mold 11, simplifying the manufacturing process and improving production efficiency. In glass press molding, it is first necessary to design and model the glass casting to be manufactured, and then import the model into the software of the 3D printer for processing. By controlling the nozzle or laser beam of the 3D printer, a specific type of sand material is stacked and bonded layer by layer to finally form a complete sand mold 11. This process can adjust the accuracy, density and structure of the sand mold 11 as needed. The use of 3D printing technology to manufacture the sand mold 11 for glass press molding not only simplifies the process time and improves efficiency, but also realizes high-precision sand mold 11 manufacturing, ensures the accuracy of the size and shape (curvature) of the product, and provides consistent production results.

[0034] The sand mold assembly 1 is composed of a plurality of sand molds 11 spliced ​​into a curved hollow structure. The plurality of sand molds 11 are interlaced and woven. A hole is formed at intervals in the middle of the sand mold assembly 1. The hole is used as an air inlet. The position of the air inlet is reserved to facilitate air circulation during product molding, effectively avoiding bubbles or defects on the product surface. In addition, after the product is molded, coolant can be sprayed to the glass casting from the air inlet.

[0035] Furthermore, the mortise and tenon structure is a connection method between components, by manufacturing protrusions (tenons) and grooves (mortise) on two mutually connected sand molds 11, so that they fit together, thereby achieving a firm connection of the structure. Using the mortise and tenon structure to connect the sand mold components 1 can make the entire mold more firm and stable, avoid displacement or loosening of the sand mold 11 during the processing process, thereby improving the precision and quality of the molded product.

[0036] Furthermore, the support steel pipe 2 refers to a steel pipe structure for supporting the sand mold assembly 1, which is fitted under the sand mold assembly 1 to provide sufficient support and stability and improve the stability of the connection between the sand molds 11. Here, the bottom of the sand mold assembly 1 refers to the side away from the pressed glass original sheet to be formed. The support steel pipe 2 is arranged under the sand mold assembly 1 to evenly distribute the load, increase the bearing capacity of the mold, prevent the mold from deformation or breakage, and increase the service life of the mold.

[0037] The guide rail 3 is a structure for guiding and positioning, which facilitates the installation of the glass processing mold on the casting equipment. And through the setting of the guide rail 3, the supporting steel pipes 2 can be connected to each other, further improving the connection strength.

[0038] The connection between the support steel pipe 2 and the sand mold assembly 1 can be achieved by using connectors such as screws, or by welding to obtain a higher connection strength. The support steel pipe 2 and the guide rail 3 can also be connected by using connectors such as screws or by welding.

[0039] See also Figure 1 to Figure 2 In this embodiment, the plurality of sand molds 11 include two first sand molds 111 arranged in parallel with each other and a plurality of second sand molds 112 arranged between the two first sand molds 111, and the plurality of second sand molds 112 are arranged in parallel with each other. The number and arrangement of the first sand mold 111 and the second sand mold 112 can be designed according to specific process requirements, which is only used as an example. In the example shown in the figure, two first sand molds 111 are provided, and four second sand molds 112 are provided. The angle between the first sand mold 111 and the second sand mold 112 is 90°, and the ends between the two first sand molds 111 are respectively connected by a second sand mold 112, and the sand mold assembly 1 is a hollow frame structure as a whole. The frame structure can share the force during the processing, reduce the load of a single sand mold 11, enhance the bearing capacity of the mold, extend the service life, and reduce the breakage or damage caused by excessive load. By rationally designing the number and arrangement of the first sand mold 111 and the second sand mold 112 and using a mortise and tenon structure to achieve convenient disassembly and connection, the number of mold changes can be reduced, saving time and labor costs.

[0040] See also Figure 1 to Figure 2In this embodiment, the mortise and tenon structure includes a mortise groove 111a provided on the first sand mold 111 and a tenon 112a provided on the second sand mold 112, and the shape of the mortise groove 111a is adapted to the tenon 112a. Due to the reliability and accuracy of the mortise and tenon structure, when the second sand mold 112 is replaced, it can be quickly and accurately clamped on the first sand mold 111, saving the time of replacing the mold and improving production efficiency. In a specific implementation, the cross-section of the mortise groove 111a is concave, and the tenon 112a is a rectangular block. Through the matching clamping of the mortise groove 111a and the tenon 112a, not only the reliability and connection stability of the mortise and tenon structure are improved, but also a certain guiding and positioning effect is provided for the connection between the first sand mold 111 and the second sand mold 112.

[0041] See also Figure 1 to Figure 2 In this embodiment, a hook portion 112b is provided on the tenon 112a. This design can make the tenon 112a and the tenon groove 111a better engage with each other to prevent loosening or falling off. The presence of the hook portion 112b can improve the strength and stability of the connection, make the wooden structure more solid and reliable, and effectively increase the stability and bearing capacity of the connection.

In addition, the number and arrangement of the supporting steel pipes 2 can reasonably disperse the pressure applied to the sand mold 11, further reduce the single-point pressure on the sand mold 11, and reduce the risk of the sand mold 11 being broken or damaged due to concentrated pressure.
