Description

Technical Field

[0001] This utility model relates to the field of glass production technology, specifically to a mold cooling device for glass production based on cold air extraction. Background Technology

[0002] Glass production molds are tools used to shape and form glass products. Their quality and performance directly affect the shape, size, precision, and production efficiency of the glass products. Cooling glass production molds essentially involves controlling the cooling rate to stabilize the molten glass and prevent mold damage. Molten glass has an extremely high temperature, and only by cooling the mold can it change from a liquid to a solid state and form a fixed shape. Cooling is a necessary condition for achieving continuous operation on an assembly line. Cooling allows the mold to recover to a usable temperature in a short time, shortening the single production cycle and increasing output per unit time. A stable cooling system can prevent the mold from needing additional cooling due to overheating, indirectly reducing the overall energy consumption cost of production.

[0003] In existing glass production processes, water is typically sprayed to cool the mold. However, the cooling water adheres to the surface of the mold and is not easy to remove, which reduces the cooling effect of subsequent cooling water and is not conducive to improving the cooling efficiency of the mold. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for glass production molds based on cold air extraction, in order to solve the problem mentioned in the background art that cooling water adheres to the surface of the mold and is not easy to remove, which leads to a reduction in the cooling effect of the subsequent cooling water and is not conducive to improving the cooling efficiency of the mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for glass production molds based on cold air extraction, comprising a protective shell with an opening on its front surface, and two maintenance door panels installed on the inner wall of the opening of the protective shell. A support frame is fixedly connected to the bottom surface of the cavity of the protective shell, and two positioning slides are installed on the upper surface of the support frame. A side clamp is fixedly connected to one end of the positioning slide. An electric push rod is fixedly connected to the upper surface of the protective shell. A cooling water spray plate is provided on the top surface of the cavity of the protective shell. A water inlet pipe is installed through the upper surface of the protective shell. Two exhaust fans are installed on the lower side surface of the protective shell. A connecting ventilation pipe is installed on the upper side surface of the protective shell. A cold air duct is fixedly installed on the inner surface of the connecting ventilation pipe. An auxiliary air duct is rotatably connected to the inner wall of the upper cavity of the protective shell. A linkage mechanism is provided on the upper surface of the cooling water spray plate.

[0006] Preferably, the inner wall of the upper cavity of the protective shell is cylindrical, and the inner wall of the lower cavity of the protective shell is square. The bottom surface of the protective shell is inclined, and a drain pipe is provided on the lower side surface of the protective shell. The protective shell and the maintenance door are rotatably connected.

[0007] By adopting the above technical solution, the inclined bottom surface can form a natural drainage slope. Combined with the drainage pipe on the lower side surface, the water generated after the cooling water is sprayed can be quickly discharged from the device, avoiding water accumulation at the bottom of the shell. If the water remains for a long time, it may corrode metal parts such as the support frame and positioning slide, shortening the service life of the equipment. At the same time, the water vapor generated by the evaporation of the water may also affect the cooling effect of the mold. This design solves this problem at its root.

[0008] Preferably, the supporting base and the positioning slide plate are slidably connected, and a spring is connected between the supporting base and the positioning slide plate, and an anti-slip pad is fixedly connected to the surface of the side clamp.

[0009] By adopting the above technical solution, the sliding connection combined with the spring structure enables the positioning slide plate to have elastic adjustment capability. When glass production molds of different widths are placed, the spring can automatically extend and retract according to the width of the mold, driving the positioning slide plate to slide, thereby allowing the side clamps to fit tightly against both sides of the mold. Stable fixation of molds of different sizes can be achieved without manual adjustment of the fixing structure, improving the adaptability of the device to various production scenarios and reducing the trouble of replacing positioning components due to changes in mold specifications.

[0010] Preferably, the cooling water spray plate and the protective shell are slidably connected, and the upper end of the cooling water spray plate is fixedly connected to the output end of the electric push rod. The lower surface of the cooling water spray plate is provided with nozzles, and the nozzles of the cooling water spray plate are connected to the water inlet pipe.

[0011] Using the above technical solution, the nozzles arranged circumferentially on the lower surface can form an annular water spraying area, which can uniformly spray cooling water from all sides of the mold to the center. Compared with single-direction or local spraying, the cooling range is wider and the speed is faster, which can shorten the mold cooling time. The nozzles are directly connected to the water inlet pipe, which can ensure the stability and continuity of the cooling water supply, avoid fluctuations in the cooling effect due to water supply interruption, and ensure that the mold cooling process is stable and efficient.

[0012] Preferably, the ventilation duct is a ring design, with one side of the cooling duct connected to the cooling pump and one end of the cooling duct connected to the auxiliary duct.

[0013] Using the above technical solution, the annular ventilation duct can form a closed airflow channel around the upper cavity of the protective shell. In conjunction with the cold air duct connected to the cold air pump, the cold air can be evenly delivered to all positions of the annular duct. Then, through the auxiliary air duct connected to the ventilation duct, air is sent to the mold area, which can avoid the cold air from concentrating in one direction, ensure that the cold air concentration around the mold is consistent, and improve the uniformity of cold air cooling.

[0014] Preferably, the linkage mechanism includes a positioning slide, which is fixedly connected to the upper surface of the cooling water spray plate. A guide slider is provided on the surface of the positioning slide, and a linkage rotating arm is installed on the surface of the guide slider.

[0015] Using the above technical solution, the positioning slide serves as the fixed carrier of the linkage mechanism and is directly fixed to the cooling water spray plate, ensuring that the movement of the linkage mechanism and the spray plate is synchronized. The guide slider on the positioning slide provides an adjustable connection point for the linkage arm, allowing the linkage arm to flexibly adjust its angle and position according to the movement of the spray plate. This lays the foundation for the coordinated action of the auxiliary air duct and the spray plate, and avoids mutual interference between the movements of various components.

[0016] Preferably, the positioning slide is slidably connected to the guide slider, the guide slider is rotatably connected to the linkage arm, and the linkage arm is rotatably connected to the auxiliary air duct.

[0017] Using the above technical solution, when the electric push rod drives the cooling water spray plate to slide up and down, the positioning slide moves synchronously with the spray plate, the guide slider slides on the positioning slide, and at the same time drives the linkage arm to rotate, thereby driving the auxiliary air duct to adjust the air delivery angle. When the spray plate moves down and approaches the mold, the auxiliary air duct can adjust its angle downward synchronously through the linkage arm, so that the cold air is blown more accurately onto the mold surface, realizing the coordinated linkage of "water cooling + air cooling", solving the problem that the cold air angle is fixed after traditional water cooling and cannot be adapted to the position of the spray plate, and greatly improving the cooling effect.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the cooling device for glass production molds based on cold air extraction:

[0019] 1. Through the dual cooling method of "cooling water spraying + cold air extraction", the circumferential nozzles of the cooling water spray plate can evenly cover the mold surface to achieve rapid cooling. The cold air delivered by the ventilation pipe and auxiliary air pipe can not only accelerate the evaporation of cooling water on the mold surface, but also further reduce the mold temperature. At the same time, the exhaust fan can promptly exhaust the hot and humid air to avoid heat retention, which solves the problems of cooling water adhesion and cooling effect attenuation in traditional single water spraying cooling.

[0020] 2. The sliding connection between the support base and the positioning slide plate, combined with the spring structure, can adapt to molds of different specifications. The anti-slip pads on the side clamps ensure no displacement during mold cooling. The electric push rod drives the cooling water spray plate to slide, and the linkage mechanism drives the auxiliary air duct to adjust the angle synchronously, which can accurately adapt to the cooling needs of molds of different heights and improve the versatility of the device.

[0021] 3. The inclined base frame and drain pipe of the protective shell facilitate the drainage of accumulated water and prevent component corrosion. The rotating connection of the maintenance door panel facilitates the maintenance of internal components. The ring-shaped ventilation pipe and directional air duct reduce air loss. The overall structure is simplified and has a low failure rate, reducing equipment operation and maintenance costs and energy consumption. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The protective shell 1 has an opening on its front surface, and two maintenance door panels 2 are installed on the inner wall of the opening. The inner wall of the upper cavity of the protective shell 1 is cylindrical. The inner wall of the cavity at the lower end of the protective shell 1 is square, the bottom surface of the protective shell 1 is inclined, and a drain pipe is provided on the lower side surface of the protective shell 1. The protective shell 1 and the maintenance door panel 2 are rotatably connected. When the maintenance door panel 2 on the front surface of the protective shell 1 is opened, the glass production mold is placed on the support base 3. The support base 3 and the positioning slide plate 4 are slidably connected, and a spring is connected between the two. When the spring is stressed, it extends and retracts, causing the positioning slide plate 4 to slide, so that the side clamp 5 at one end of the positioning slide plate 4 is tightly attached to both sides of the mold. The anti-slip rubber pad 6 on the surface of the side clamp 5 increases the friction and achieves stable fixation of the mold.

[0031] A support frame 3 is fixedly connected to the bottom surface of the cavity of the protective shell 1. Two positioning slide plates 4 are installed on the upper surface of the support frame 3. A side clamping plate 5 is fixedly connected to one end of the positioning slide plate 4. An electric push rod 7 is fixedly connected to the upper surface of the protective shell 1.

The support frame 3 and the positioning slide plates 4 are slidably connected, and a spring is connected between the support frame 3 and the positioning slide plates 4. An anti-slip pad 6 is fixedly connected to the surface of the side clamping plate 5. When the electric push rod 7 is activated, the output end of the electric push rod 7 drives the cooling water spray plate 8 fixed thereto to slide along the protective shell 1 and adjust it to a height that matches the mold. Water is supplied to the cooling water spray plate 8 through the water inlet pipe 9 on the upper surface of the protective shell 1. The cooling water is evenly sprayed onto the mold surface through the circumferential nozzles on the lower surface of the cooling water spray plate 8. The specific heat capacity of water is used to absorb the heat of the mold and achieve initial cooling.

[0032] Two exhaust fans 10 are installed on the lower side surface of the protective housing 1. A connecting ventilation pipe 11 is installed on the upper side surface of the protective housing 1. A cooling air duct 12 is fixedly installed on the inner side surface of the connecting ventilation pipe 11. A cooling water spray plate 8 is slidably connected to the protective housing 1, and the upper end of the cooling water spray plate 8 is fixedly connected to the output end of the electric push rod 7. Nozzles are arranged circumferentially on the lower surface of the cooling water spray plate 8, and the nozzles of the cooling water spray plate 8 are connected to the water inlet pipe 9. The connecting ventilation pipe 11 is a ring design, with a cooling air duct on one side. 12 is connected to the cold air pump. One end of the cold air duct 12 is connected to the auxiliary air duct 13. When the cold air pump is turned on, the cold air is delivered to the annular connecting ventilation duct 11 through the cold air duct 12 connected to the cold air pump. Then, it is distributed to the auxiliary air duct 13 through the connecting ventilation duct 11. The auxiliary air duct 13 blows the cold air toward the mold area to accelerate the evaporation of cooling water on the mold surface and further remove the heat from the mold. At the same time, the exhaust fan 10 on the lower side surface of the protective shell 1 is started to extract the hot and humid air in the device to avoid heat accumulation and affect the cooling effect.

[0033] An auxiliary air duct 13 is rotatably connected to the inner wall of the cavity at the upper end of the protective shell 1. A linkage mechanism is provided on the upper surface of the cooling water spray plate 8. The linkage mechanism includes a positioning slide 14, which is fixedly connected to the upper surface of the cooling water spray plate 8. A guide slider 15 is provided on the surface of the positioning slide 14, and a linkage rotating arm 16 is installed on the surface of the guide slider 15. The positioning slide 14 and the guide slider 15 are slidably connected, and the guide slider 15 and the linkage rotating arm 16 are rotatably connected. The linkage rotating arm 16 is also rotatably connected to the auxiliary air duct 13. During the up-and-down sliding of the cooling water spray plate 8, the positioning slide 14 fixed on its surface moves synchronously. The positioning slide 14 and the guide slider 15 are slidably connected. The guide slider 15 moves with the positioning slide 14 and slides along the slide. At the same time, the guide slider 15 drives the linkage rotating arm 16, which is rotatably connected to it, to move. The linkage rotating arm 16 drives the auxiliary air duct 13, which is rotatably connected to it, to adjust the air delivery angle to ensure that the cold air always accurately covers the mold, realizing the synergistic cooling of "water cooling + air cooling".

[0034] Working principle: When using this glass production mold cooling device based on cold air extraction, open the maintenance door 2, place the mold on the support base 3, and the positioning slide plate 4 drives the side clamp plate 5 to fix the mold under the action of the spring. Then, the electric push rod 7 drives the cooling water spray plate 8 to slide to the appropriate height, the water inlet pipe 9 supplies water, and the nozzle sprays cooling water onto the mold for initial cooling. Subsequently, the cold air pump sends cold air to the auxiliary air pipe 13 through the cold air duct 12 and the connecting ventilation pipe 11 to accelerate the evaporation of moisture and cool it down again. The exhaust fan 10 simultaneously discharges the hot and humid air. During cooling, the cooling water spray plate 8 drives the positioning slide 14 to move, the guide slider 15 slides and drives the auxiliary air pipe 13 to adjust the angle through the linkage rotating arm 16 to ensure accurate coverage of cold air, achieve efficient and coordinated cooling, and increase the overall practicality.
