[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Refer to the attached Figure 1 and attached Figure 2 , the utility model provides an embodiment: an exhaust and heat-insulating glass mold, comprising a mold body 1, a compression mold cavity 8 is opened on the inner side of the mold body 1, and a plurality of exhaust holes 7 are opened on the inner side of the mold body 1, which can make the gas in the glass and other gases generated by high temperature discharge the mold body 1 more smoothly when the glass is injected into the compression mold cavity 8, effectively avoiding defects such as air holes in the glass products, and a vertical cooling hole outlet 10 is opened in the middle of the mold body 1, which is arranged at the waist, thereby increasing the cooling effect of the mold waist, and a heat preservation sleeve 9 is fixedly connected to the rear side of the mold body 1, thereby reducing the cooling speed of the root of the mold bottle, and a disassembly mechanism 2 is provided on the outer wall of the heat preservation sleeve 9; the outer wall of the compression mold cavity 8 is provided with stripes 11, which increase the friction between the glass product and the mold, thereby preventing the glass product from sliding or deflecting during the molding process, ensuring the shape and size accuracy of the glass product, and further improving the product quality;

[0040] Specifically, the design of multiple rows of exhaust holes 7 increases the exhaust volume during molding, so that the gas in the glass and other gases generated by high temperature can be discharged from the mold body 1 more smoothly, which effectively avoids defects such as pores in the glass products and greatly improves the quality of the glass products. The application of the insulation sleeve 9 reduces the cooling speed of the root of the molded bottle. Since the root of the bottle is relatively thick, excessive cooling in the past will cause uneven stress inside the glass, affecting the strength and quality of the product. Now the glass at the root of the bottle has enough time to cool slowly, thereby reducing internal stress and improving the overall performance of the glass product. The outermost vertical cooling hole outlet 10 is set at the waist, which increases the cooling effect of the mold waist. This can make the temperature of the upper, middle and lower parts of the mold more uniform, avoid problems such as inconsistent shrinkage and stress concentration caused by uneven temperature, and further improve the quality of the glass products. By arranging multiple stripes 11 on the outer wall of the die cavity 8, the friction between the glass product and the mold can be increased, preventing the glass product from sliding or offsetting during the molding process, ensuring the shape and size accuracy of the glass product, and further improving the product quality.

[0041] Refer to the attached Figure 3 , Attachment Figure 4 and attached Figure 5 , the disassembly mechanism 2 includes a sealing cover 202, the left side of the sealing cover 202 is fixedly connected to the right side of the thermal insulation sleeve 9, and the left side of the sealing cover 202 is fixedly connected to a sealing ring 203. The sealing cover 202 fits tightly with the mold body 1 through the sealing ring 203, which plays a good sealing role. A hole 201 is opened on the right side of the mold body 1, and the outer wall of the thermal insulation sleeve 9 is slidably connected to the inner side of the hole 201. The right side of the sealing cover 202 is fixedly connected to a pull rod 204; the outer wall of the pull rod 204 is fixedly connected to a handle 205, and the outer wall of the handle 205 is made of silicone material, which increases the convenience of operation for the staff;

[0042] Specifically, the outer wall of the insulation sleeve 9 is slidably connected in the hole 201. By holding the handle 205 to drive the pull rod 204, and then pulling the sealing cover 202 and the insulation sleeve 9, the insulation sleeve 9 can be pulled out from the hole 201 of the mold body 1 for replacement or repair. This greatly improves the convenience of mold maintenance, reduces the overall mold downtime caused by damage to the insulation sleeve 9, and improves production efficiency.

[0043] Refer to the attached Figure 1, the front and rear sides of the top of the mold body 1 are fixedly connected with connecting plates 3; the tops of the two connecting plates 3 are each provided with a through hole 4, and the inner sides of the through holes 4 are threadedly connected with bolts 5. The upper and lower molds can be tightly connected together by the bolts 5 to form an integral production unit, which improves production efficiency while ensuring the position of each mold is fixed, making the consistency of the glass products better; the outer wall of the bolt 5 is threadedly connected with a nut 6; the diameter of the bolt 5 is adapted to the inner diameter of the through hole 4, ensuring the tightness and precision of the connection;

[0044] Specifically, the connecting plate 3 fixedly connected to the front and rear sides of the top of the mold body 1 provides an additional connection point and support structure for the mold. The through holes 4 on the connecting plate 3 cooperate with the bolts 5 and nuts 6 to firmly connect the upper and lower molds. During the glass forming process, the mold needs to withstand various forces such as high temperature, high pressure and the impact of glass liquid. This stable connection method can ensure that the mold will not loosen or move during operation, thereby ensuring the dimensional accuracy and quality stability of the glass products.

[0045] Working principle: By designing multiple rows of exhaust holes 7, when the molten glass is injected into the die cavity 8 of the mold body 1, the gas in the glass and other gases generated by the high temperature need to be discharged. The exhaust holes 7 can increase the exhaust volume during molding, so that the gas can be discharged from the mold body 1 more smoothly. The rear side of the mold body 1 is fixedly connected with an insulation sleeve 9 with a length of 58 mm, which is inserted into the root of the vertical cooling hole bottle. Since the root of the bottle is relatively thick, if it is cooled too quickly during the molding process, it will cause uneven stress inside the glass, affecting the strength and quality of the glass product. The insulation sleeve 9 can reduce the cooling speed of the molded bottle root, so that the glass at the bottle root can There is enough time for slow cooling, thereby reducing internal stress and improving the overall performance of glass products. The position of the outermost vertical cooling hole outlet 10 is set at the waist to increase the cooling effect of the mold waist, and the outer wall of the insulation sleeve 9 is slidably connected to the inner side of the hole 201. The operator holds the handle 205 and drives the pull rod 204 to pull the sealing cover 202 and the insulation sleeve 9, thereby pulling the insulation sleeve 9 out of the hole 201 of the mold body 1 for replacement or maintenance. When the insulation sleeve 9 is inserted into the hole 201 on the right side of the mold body 1, the sealing cover 202 fits tightly with the mold body 1 through the sealing ring 203 to play a sealing role.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
