Description

Technical Field

[0001] This utility model relates to the field of glass product processing technology, and in particular to a glass product manufacturing mold. Background Technology

[0002] Glass products are various items made primarily of glass. They possess characteristics such as transparency, corrosion resistance, high temperature resistance, and recyclability. Their history can be traced back to ancient Egypt, and they are now widely used in construction, daily necessities, medical care, electronics, and other fields. The production process includes melting, forming, and heat treatment. Products encompass daily-use glass, architectural glass, and specialty glass, making them indispensable materials for modern industry and daily life, combining practicality and environmental value.

[0003] For example, the Chinese patent with authorization announcement number CN212982778U discloses a fast-heat-dissipating and efficient glass bottle production mold. This fast-heat-dissipating and efficient glass bottle production mold has a fixed mold and a moving mold set on the upper surface of the base. The outer wall of the fixed mold has four forming cavities, which correspond to the feeding groove. Through the cooperation of the left forming cavity, the right forming cavity, the positioning plate, the hydraulic column and the moving mold forming cavity, it can realize the function of forming four glass products at one time, which can effectively improve the production efficiency of the mold for glass products and is suitable for promotion and popularization. By setting a first through hole and a second through hole on the inner wall of the fixed mold and the two moving molds respectively, the first and second through holes correspond to the fan blades. Through the cooperation of the rotating shaft, transmission belt, motor, water tank pump and atomizing nozzle, the atomized cold water enters the first and second through holes, which can effectively cool down the mold and ensure the cooling effect of the glass products inside the cavity. The above patent achieves simultaneous production and heat dissipation of multiple bottles through the combination of fixed mold, moving mold, fan blades and through holes. However, since the through hole is a straight structure, the atomized gas is difficult to effectively penetrate into the connection area between the moving mold and the fixed mold, resulting in insufficient cooling in this part. This uneven heat dissipation will cause the cooling rate difference in local areas of the glass bottle surface, resulting in thermal stress concentration, which may lead to cracking of glass products, deformation of mold or unstable quality of finished products, affecting production yield and mold life. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a glass product manufacturing mold. By setting up a first cavity, a second cavity, a first flow guide cavity, and a second flow guide cavity, it can not only produce multiple glass products at the same time, but also achieve uniform cooling for each glass product.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a glass product manufacturing mold, including a base plate, a top plate fixedly installed around the top of the base plate by columns, a cylindrical fixed mold fixedly installed at the top center of the base plate, a plurality of first cavities arranged in a circular pattern on the outer side of the cylindrical fixed mold, a plurality of arc-shaped moving molds arranged in a circular pattern on the outer side of the cylindrical fixed mold, and a second cavity opened on the inner side of the arc-shaped moving mold; The cylindrical mold is internally and externally fixedly equipped with an exhaust mechanism for rapid and uniform heat dissipation from the first and second cavities. The top of the cylindrical fixed mold is arranged in a circular pattern and is equipped with a power mechanism for driving the relative position between the cylindrical fixed mold and the arc-shaped moving mold.

[0006] As a preferred embodiment of this utility model, the exhaust mechanism includes a rotating air supply pipe, an arc-shaped diverter pipe, and an air inlet pipe. A cylindrical cavity is formed at the bottom of the cylindrical fixed mold. The rotating air supply pipe is rotatably connected to the top center of the base plate and is located inside the cylindrical cavity. The arc-shaped diverter pipe is fixedly installed on the outside of the rotating air supply pipe. The air inlet pipe is fixedly installed at the bottom center of the base plate and communicates with the rotating air supply pipe. A first guide cavity is formed on the inner wall of the cylindrical cavity, and a second guide cavity is formed on the outside of the arc-shaped moving mold. The first guide cavity and the second guide cavity communicate with each other.

[0007] As a preferred technical solution of this utility model, the power mechanism includes a drive motor, a power disc, and a power cylindrical locking block. The drive motor is fixedly installed at the top center of the top plate, and the bottom end of the drive motor penetrates through the bottom of the top plate. The power disc is fixedly installed at the output end of the drive motor extending out of the bottom of the top plate. The top of the power disc has multiple arc-shaped slots arranged in a circle, and the bottom of the top plate has multiple limiting slots arranged in a circle.

[0008] As a preferred embodiment of this utility model, the top center of the cylindrical mold is provided with a feed port, and a mold chamber is formed between the first cavity and the second cavity. The mold chamber and the feed port are connected by a flow divider.

The stabilizing slots are slidably engaged with stabilizing blocks, and the top of the stabilizing blocks are fixedly installed with the bottom of the arc-shaped moving mold.

[0010] Compared with the prior art, the beneficial effects that this utility model can achieve are: During the manufacturing of glass products, a power mechanism synchronously drives multiple arc-shaped moving molds to move, forming a mold chamber between the second cavity and the first cavity. At this time, molten glass is injected into the mold chambers respectively. Then, the exhaust mechanism guides the flow of cold air to accelerate the discharge of hot air from each mold chamber and neutralize the heat. This allows the exhaust mechanism to achieve synchronous and uniform cooling of each mold chamber. This uniform heat dissipation ensures that the cooling rate of each area on the surface of the glass bottle is consistent, avoiding thermal stress concentration. This effectively prevents cracking of glass products, mold deformation, and fluctuations in finished product quality, ensuring stable production yield and extending the service life of the mold.

[0014] Reference Appendix Figure 1 ,exist Figure 1 In the diagram, 'a' points to the front view and 'b' points to the right-side view. These views are only used to understand the scheme.

[0015] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this utility model provides a glass product manufacturing mold, including a base plate 1, a top plate 11 fixedly installed around the top of the base plate 1 by columns, a cylindrical fixed mold 2 fixedly installed at the top center of the base plate 1, a plurality of first cavities 21 arranged in a circle on the outer side of the cylindrical fixed mold 2, a plurality of arc-shaped moving molds 3 arranged in a circle on the outer side of the cylindrical fixed mold 2, and a second cavity 31 opened on the inner side of the arc-shaped moving molds 3. The cylindrical mold 2 has an exhaust mechanism that is fixedly installed inside and outside for rapid and uniform heat dissipation from the first cavity 21 and the second cavity 31. The top of the cylindrical fixed mold 2 is arranged in a circular pattern and is equipped with a power mechanism for driving the relative position between the cylindrical fixed mold 2 and the arc-shaped moving mold 3.

[0016] In this case, the exhaust mechanism is connected to an external negative pressure cooling device. During the production of glass products, the power mechanism synchronously drives multiple arc-shaped moving molds 3 to move, so that a mold chamber is formed between the second cavity 31 and the first cavity 21. At this time, molten glass is injected into the mold chambers respectively. Then, the exhaust mechanism guides the flow of cold air to accelerate the discharge of hot air from each mold chamber and neutralize the heat. This allows the exhaust mechanism to achieve synchronous and uniform cooling of each mold chamber. This uniform heat dissipation ensures that the cooling rate of each area on the surface of the glass bottle is consistent, avoids thermal stress concentration, and effectively prevents cracking of glass products, mold deformation and fluctuation of finished product quality, ensures stable production yield and extends the service life of the mold.

[0017] The exhaust mechanism includes a rotating air supply pipe 41, an arc-shaped diverter pipe 42, and an air inlet pipe 43. A cylindrical cavity 4 is opened at the bottom of the cylindrical fixed mold 2. The rotating air supply pipe 41 is rotatably connected to the top center of the base plate 1 and is located inside the cylindrical cavity 4. The arc-shaped diverter pipe 42 is fixedly installed on the outside of the rotating air supply pipe 41. The air inlet pipe 43 is fixedly installed at the bottom center of the base plate 1 and is connected to the rotating air supply pipe 41. A first guide cavity 44 is opened on the inner wall of the cylindrical cavity 4, and a second guide cavity 45 is opened on the outside of the arc-shaped moving mold 3. The first guide cavity 44 and the second guide cavity 45 are connected.

[0018] The bottom of the air inlet pipe 43 is connected to an external negative pressure cooling device. When the molten glass is injected into the mold cavity, the cold air enters the rotating air supply pipe 41 through the air inlet pipe 43 and is then ejected through the arc-shaped diverter pipe 42. Due to the negative pressure gas ejecting and impacting the inner wall of the cylindrical cavity 4, the thrust of the negative pressure gas drives the rotating air supply pipe 41 to rotate through the arc-shaped diverter pipe 42. The rotating air supply pipe 41 drives multiple arc-shaped diverter pipes 42 to rotate and eject negative pressure cold air, making the cold air fill the interior of the cylindrical cavity 4. At the same time, it also accelerates the speed at which the cold air enters the first guide cavity 44. After entering the first guide cavity 44, the cold air flows into the second guide cavity 45 and is discharged through the second guide cavity 45. During this period, the cold air neutralizes the heat generated in the mold cavity and accelerates the heat flow to the outside. Since the first guide cavity 44 and the second guide cavity 45 are wrapped around the outside of the mold cavity, the effect of uniform heat dissipation for the glass product is achieved.

[0019] The power mechanism includes a drive motor 5, a power disc 51, and a power cylindrical locking block 54. The drive motor 5 is fixedly installed at the top center of the top plate 11, and the bottom end of the drive motor 5 penetrates through the bottom of the top plate 11. The power disc 51 is fixedly installed at the output end of the drive motor 5 extending out of the bottom of the top plate 11. The top of the power disc 51 has multiple arc-shaped slots 52 arranged in a circle, and the bottom of the top plate 11 has multiple limiting slots 53 arranged in a circle. The top end of the power cylindrical locking block 54 is slidably engaged in the limiting slot 53, the outer side of the power cylindrical locking block 54 is slidably engaged with the arc-shaped slot 52, and the bottom of the power cylindrical locking block 54 is fixedly installed with the top of the arc-shaped moving mold 3.

[0020] When glass products need to be made, the drive motor 5 is started, which drives the power disc 51 to rotate. The power disc 51 drives the arc-shaped slot 52 to rotate. Under the restriction of the limiting slot 53, the arc-shaped slot 52 drives the power cylindrical slot 54 to move towards the center. The power cylindrical slot 54 drives the arc-shaped moving mold 3 to move towards the center, so that the arc-shaped moving mold 3 fits against the outside of the cylindrical fixed mold 2, connecting the first cavity 21 and the second cavity 31 to form a mold chamber. Similarly, the working principle of the synchronous movement of the other arc-shaped moving molds 3 is the same. By driving the drive motor 5 to drive multiple arc-shaped moving molds 3 to move synchronously and fit against the cylindrical fixed mold 2, multiple glass products can be produced at the same time.

[0021] The cylindrical mold 2 has a feed port 6 at the top center. A mold chamber is formed between the first cavity 21 and the second cavity 31. The mold chamber and the feed port 6 are connected by a flow channel 61.

[0022] This allows the molten glass to flow into the distribution channel 61 through the inlet 6, and then be injected into the corresponding mold cavity through the distribution channel 61.

[0023] The top of the base plate 1 and the outer side of the cylindrical fixed mold 2 are provided with multiple stabilizing slots arranged in a circle. The stabilizing slots are slidably engaged with stabilizing blocks, and the top of the stabilizing blocks are fixedly installed with the bottom of the arc-shaped moving mold 3.

[0024] The stability of the arc-shaped moving mold 3 during movement is increased by using stabilizing slots and stabilizing blocks.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
