[0002] Glass substrate (also known as glass substrate) is a thin sheet-like substrate made of glass as the core material. It is mainly used in the fields of electronic display and semiconductor packaging. As an important basic material of the modern electronics industry, glass substrate plays an irreplaceable role in the fields of flat panel display and semiconductor packaging. Its high flatness, excellent electrical performance and wide range of applications make it an important driving force for technological development.

[0003] During the production and processing of glass substrates, they are usually cast into shape using casting molds. This involves pouring molten glass material into a forming mold, then cooling and solidifying it before demolding it out of the mold to obtain a pre-formed glass substrate.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 4 A glass substrate casting mold includes: a mold body 1, wherein a circulating cooling mechanism 2 for rapid cooling is provided inside the mold body 1; and a convenient demolding mechanism 6, which is located on the top of the mold body 1 for lifting and demolding the formed glass substrate.

[0022] The circulating cooling mechanism 2 includes a heat-conducting copper block 201, a heat-conducting cooling component 3, and a circulation component 4. The mold body 1 includes a lower mold 101. The heat-conducting copper block 201 is fixedly connected to the middle of the lower mold 101. The heat-conducting cooling component 3 is installed inside the lower mold 101. The circulation component 4 is installed at the bottom of the lower mold 101.

[0023] The heat conduction and cooling component 3 includes a first coolant tank 301, a second coolant tank 302, a first high-pressure pump 303, a liquid guide pipe 304, and a cooling channel 305. The first coolant tank 301 and the second coolant tank 302 are symmetrically opened inside the lower mold 101. The first high-pressure pump 303 is fixedly connected to the inner bottom end of the first coolant tank 301. One end of the liquid guide pipe 304 is fixedly connected to one end of the first high-pressure pump 303. The cooling channel 305 is opened inside the heat-conducting copper block 201, and one end of the cooling channel 305 is connected to the other end of the liquid guide pipe 304. The other end of the cooling channel 305 is connected to the second coolant tank 302.

[0024] The circulation assembly 4 includes a second high-pressure pump 401, a circulation heat pipe 402, and two air-cooling units 5. The second high-pressure pump 401 is fixedly connected to the inner bottom of the second coolant tank 302. The two ends of the circulation heat pipe 402 are fixedly connected to the bottom of the first coolant tank 301 and the bottom of the second coolant tank 302 respectively through the bottom of the lower mold 101. One end of the circulation heat pipe 402 is fixedly connected to one end of the second high-pressure pump 401. The two air-cooling units 5 are symmetrically installed at the bottom of the lower mold 101.

[0025] The air-cooled unit 5 includes a fixed frame 501, a motor 502 and a fan impeller 503. The two ends of the fixed frame 501 are fixedly connected to the bottom of the lower mold 101, the motor 502 is fixedly connected to the middle of the fixed frame 501, and the middle of the fan impeller 503 is fixedly connected to the output end of the motor 502 by rotating through the middle of the fixed frame 501.

[0026] The mold body 1 also includes an upper mold 102, a number of positioning rods 103 and a number of positioning holes 104. One end of the number of positioning rods 103 is symmetrically fixed to the bottom of the upper mold 102, and the number of positioning holes 104 are symmetrically opened on the top of the lower mold 101. The upper mold 102 and the lower mold 101 are precisely matched and connected through the number of positioning rods 103 and the number of positioning holes 104.

[0027] In the specific implementation process, firstly, the upper mold 102 and lower mold 101 are precisely aligned and connected by the positioning rod 103 and positioning hole 104. Then, molten glass material is poured into the molded cavity after mold closing through the casting port at the top of the upper mold 102. At this time, the heat-conducting copper block 201 absorbs and conducts heat from the glass material. The first high-pressure pump 303 provides force to conduct the coolant stored in the first coolant tank 301 to the connected cooling channel 305 through the liquid guide pipe 304. As the coolant flows through the cooling channel 305, the heat absorbed by the heat-conducting copper block 201 is absorbed and conducted into the coolant. The cooled coolant, after absorbing heat, flows into the second coolant tank 302 through the cooling channel 305. Then, the second high-pressure pump 401 starts to... The system provides force to draw the coolant flowing into the second coolant tank 302 into the circulating heat dissipation pipe 402. As the coolant flows through the pipe, heat is dissipated to the external environment. The motor 502, supported by a bracket 501, is activated, driving the connected fan impeller 503 to rotate. This rotation generates airflow, further dissipating the heat from the coolant. The cooled coolant then flows back into the first coolant tank 301 through the circulating heat dissipation pipe 402 for reuse. This facilitates heat absorption, conduction, and circulating cooling of molten glass, eliminating the need for prolonged cooling and solidification, effectively increasing the cooling and solidification rate, and ultimately improving production efficiency.

[0028] Furthermore, the convenient demolding mechanism 6 includes two mating grooves 601, two lifting plates 602, and several limiting sliders 603. The two mating grooves 601 are symmetrically opened on the top of the lower mold 101, and the side walls of the two lifting plates 602 are slidably connected to the side walls of the two mating grooves 601 respectively through several limiting sliders 603.

[0029] It should be noted that after the glass material is cooled and solidified, the upper mold 102 is opened to expose the solidified glass substrate. Then, the lifting plate 602 is pulled upwards and slides upwards within the mating groove 601 by the limiting slider 603. As the lifting plate 602 moves upwards within the mating groove 601, a force is applied from the bottom of the solidified glass substrate, causing it to be lifted and removed from the forming cavity of the lower mold 101. This facilitates the lifting and demolding of the solidified glass substrate without the need for hammering, effectively improving the final product qualification rate.

[0030] The working principle of the glass substrate casting mold provided by this utility model is as follows:

[0031] In use, firstly, the upper mold 102 and lower mold 101 are precisely aligned and connected via the positioning rod 103 and positioning hole 104. Then, molten glass material is poured into the molded cavity after mold closing through the casting port at the top of the upper mold 102. At this time, the heat-conducting copper block 201 absorbs and conducts heat from the glass material. The first high-pressure pump 303 provides force to conduct the coolant stored in the first coolant tank 301 through the liquid guide pipe 304 to the connected cooling channel 305, thereby cooling the glass material. The coolant flows through the cooling channel 305, thus absorbing and transferring the heat absorbed by the heat-conducting copper block 201 into the coolant. The cooled coolant, after absorbing heat, flows through the cooling channel 305 into the second coolant tank 302. The second high-pressure pump 401 then provides the force to draw the coolant from the second coolant tank 302 into the circulating heat dissipation pipe 402. The coolant flows through the circulating heat dissipation pipe 402, dissipating heat into the external environment. The pump 502, supported by a mounting bracket 501, further enhances the cooling effect. The force drives the connected fan impeller 503 to rotate. The rotation of the fan impeller 503 generates airflow, further dissipating the heat from the coolant into the external environment. The cooled coolant, after heat dissipation, can then flow back into the first coolant tank 301 through the circulating heat dissipation pipe 402 for reuse. This effectively facilitates heat absorption, conduction, and circulating cooling of the molten glass material, eliminating the need for prolonged waiting for the glass to cool and solidify. This significantly increases the cooling, solidification, and molding rate, thereby improving production efficiency. Secondly, the glass… After the glass material is cooled and solidified, the upper mold 102 is opened to expose the formed glass substrate. Then, the lifting plate 602 is pulled upward and slids upward within the fitting groove 601 by the limiting slider 603. As the lifting plate 602 moves upward within the fitting groove 601, a force is applied from the bottom of the formed glass substrate, causing it to be lifted and removed from the forming cavity of the lower mold 101. This effectively facilitates the lifting and demolding of the solidified glass substrate without the need for knocking, thus improving the final product qualification rate.
