Description

Technical Field

[0001] The utility model belongs to the technical field of plastic production cooling, in particular to a plastic gear box production cooling device. Background Art

[0002] Gears are mechanical parts with teeth that mesh with each other, and plastic gears are a type of gear. They are used in various industries such as micromotors, electronic products, auto parts, home appliances, office supplies, toys, and handicrafts. Different gear combinations are used in products such as car rearview mirrors, printers, fax machines, toy movements, instruments and meters, medical equipment, vacuum cleaners, and automatic coffee machines.

[0003] A patent with announcement number CN 220784582 U discloses a cooling device for processing plastic gears, including a cooling box body, an outer wall of one side of the cooling box body is provided with a feed port, a supporting mechanism is fixedly provided inside the cooling box body, the top of the supporting mechanism is fixedly connected to a water tank, an outer wall of one side of the water tank is fixedly connected to a water outlet pipe, and one end of the water outlet pipe extends into the interior of the cooling box body, and a sprinkler nozzle is fixedly installed at one end of the water outlet pipe, which can easily remove the cooled plastic gear from the cooling water tank. However, water droplets still remain on the surface of the plastic gear that has just been cooled. When the residual heat inside the plastic gear gradually dries up the plastic gear, the evaporated water droplets will leave water spots on the surface of the plastic gear.

[0004] At present, in the existing technology, plastic parts are cooled by passing through water during the cooling process, and the low-temperature water is used to cool the plastic parts. However, the cooling effect is generally poor, and a long cooling pool needs to be laid for cooling. This not only has a low cooling effect, but also the plastic parts that have just been demolded have residual injection heat inside and outside. The plastic parts will expand and contract during the cooling process of the cooling water, which may cause the size of the plastic parts to change. The uneven cooling rate may cause stress inside the plastic parts. These internal stresses may cause the plastic parts to deform or crack during subsequent use. After the low-temperature water is used for cooling, water will remain on the surface of the plastic parts. As the residual heat of the plastic parts continues to dry and evaporate, the plastic parts after the water evaporates will leave water spots or mineral deposits on the surface of the plastic parts, affecting the appearance of the product.

[0005] Therefore, in order to solve the above problems, a plastic gearbox production cooling device is proposed. Utility Model Content

[0015] Beneficial effects of the utility model:

[0016] The utility model provides a plastic gear box production cooling device, in which both side surfaces of the rising aggregate box are aligned with one end of the air pipe and the return air pipe, and at this time, the inside of the air pipe is quickly blown by a blower, and the infused air is accumulated inside the aggregate box, and the gas accumulated inside the aggregate box enters the inside of the condensation extractor through the return air pipe. By utilizing the sealing of the aggregate box surface, the gas can only enter the inside of the condensation extractor from the inside of the return air pipe, and the high-speed flowing gas impacts the plastic gears inside the aggregate box, and in the process of impact, the water source remaining on the surface of the plastic gear is cleaned away, so that the water source is cleaned away by the push of the gas, thereby reducing the residence time of water droplets on the surface of the plastic gear, and avoiding the effect of water spots on the surface of the plastic gear caused by drying up of the water source;

The circulating flow of the water source will change the surface of the plastic gear to always maintain it in a low-temperature state, and the temperature will not increase after the water source absorbs heat, thereby reducing the cooling effect.

[0026] The following will be combined with the accompanying 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.

[0027] Specific examples are given below.

[0028] See also Figure 1 - Figure 6 The utility model provides a plastic gearbox production cooling device, comprising a support pad 11 and a cooling box 12 fixedly mounted on the outer surface of the top of the support pad 11, an electric winder 13 detachably mounted on the outer surface of the top of the cooling box 12, a collecting box 14 slidably sleeved on the inner wall of the cooling box 12, a supporting foot 115 fixedly mounted on the top surface of the support pad 11 and located on one side edge of the cooling box 12, a blower 116 fixedly mounted on the top surface of the supporting foot 115, an air pipe 117 and an air return pipe 114 symmetrically fixedly mounted on both side surfaces of the cooling box 12, the other end of the air pipe 117 is connected to the air outlet of the output end of the blower 116, and the other end of the return pipe 114 is fixedly mounted with a condensation extractor 112 arranged on one side edge of the top of the support pad 11;

[0029] During operation, the injection-molded plastic gear is placed into the collecting box 14, and the collecting box 14 is lowered to the deep inside of the cooling box 12 with the help of the electric winder 13. At this time, the surface of the plastic gear is briefly immersed in the low-temperature water source inside the cooling box 12 to initially cool the plastic gear. The collecting box 14 is then raised by the electric winder 13 to quickly separate the plastic gear inside the collecting box 14 from the cooling water, thereby reducing the excessive contact between the low-temperature cooling water and the plastic gear, which in turn causes the plastic gear material to expand and contract during the cooling process. The short low-temperature contact can greatly avoid the cracking of the plastic surface caused by the concentration of thermal stress caused by rapid temperature changes.

[0030] The two side surfaces of the rising aggregate box 14 will be aligned with one end of the air pipe 117 and the return air pipe 114. At this time, the air inside the air pipe 117 will be blown quickly by the blower 116. The infused air will accumulate inside the aggregate box 14. The gas accumulated inside the aggregate box 14 will enter the interior of the condensation extractor 112 through the return air pipe 114. The closed surface of the aggregate box 14 allows the gas to enter the interior of the condensation extractor 112 only from the inside of the return air pipe 114. The high-speed flowing gas will impact the plastic gears inside the aggregate box 14, impacting the plastic gears inside the aggregate box 14. In the process of gasification, the residual water source on the surface of the plastic gear is cleaned up, so that the water source is pushed away by the gas, reducing the residence time of water droplets on the surface of the plastic gear, and avoiding the effect of water spots on the surface of the plastic gear due to drying up of the water source; and in the process of vaporization, the water source will absorb heat from the outside world in order to overcome the mutual attraction between molecules, and the vaporized water source is used to perform secondary absorption and heat dissipation treatment on the residual heat source on the surface of the plastic gear. Since the air source cooling is relatively uniform and soft, no rapid cooling will occur, and it will not cause cracks on the surface of the plastic gear.

[0031] Further, such as Figures 1 to 6As shown, a return water pipe 111 is fixedly connected to the bottom surface of the support pad 11 and located at the bottom edge of the cooling box 12, one end of the return water pipe 111 is fixedly connected to the receiving end of the condensation extractor 112, and the other end of the return water pipe 111 passes through the cooling box 12 and extends to the inner wall surface, and a push water pipe 113 extending to the inner wall surface of the cooling box 12 is fixedly connected to the output end of the cooling box 12, and the top surface of the collection box 14 is movably connected with a closing cover plate 141, and the four inner corners of the collection box 14 are provided with a snap-fitting gasket groove 143 that is movably connected to the outer surface of the closing cover plate 141, and limiting grooves 145 are provided on both side surfaces of the collection box 14, and a permeable grid plate 142 is provided on the other two side surfaces of the collection box 14, and a pad plate 14 is fixedly connected to the bottom inner wall surface of the collection box 14 4. A support pad 131 is fixedly connected to the top edge position of the cooling box 12 and located on the outer surface. A limiting rod 132 is movably sleeved on the top of the support pad 131. A pull rope 133 that is movably sleeved on the outer surface of the limiting rod 132 is fixedly connected to the output end of the electric winder 13. One end of the pull rope 133 is fixedly connected to the top edge position of the collection box 14. A support pad 122 is fixedly connected to the inner wall surface of the cooling box 12, and the bottom surface of the collection box 14 is movably overlapped on the top surface of the support pad 122. A water collecting trough 123 is provided on the bottom inner wall surface of the cooling box 12 and located at the bottom edge position of the collection box 14. A limiting strip 121 is fixedly connected to the inner wall surface of the cooling box 12, and the outer surface of the limiting strip 121 is movably sleeved on the outer surface of the limiting groove 145.

[0032] During operation, the electric winder 13 is used to lower the collection box 14 for collecting plastic gears into the deep inside of the cooling box 12, and the low-temperature water source inside the cooling box 12 is used to contact the plastic gears inside the collection box 14, and the low-temperature water source is used to quickly cool down the plastic gears inside the collection box 14. At this time, the condensation extractor 112 is used to infuse water into the inside of the push water pipe 113, and the impact of the water source is used to stir the low-temperature water source inside the cooling box 12. The excess water source will be absorbed into the inside of the condensation extractor 112 through the return water pipe 111. The circulating flow of the water source will change the surface of the plastic gear to always remain in a low temperature state, and the temperature will not increase after the water source absorbs heat, thereby reducing the cooling effect. The continuously flowing water source will drive the movement of warm water. At the same time, the water source that moves too much will dissipate the heat source through the return water pipe 111, thereby achieving continuous cooling and fluidity cooling.

[0033] Working principle: Put the injection-molded plastic gear into the collecting box 14, and lower the collecting box 14 to the deep inside of the cooling box 12 with the help of the electric winder 13. At this time, cooperate with the low-temperature water source inside the cooling box 12 to briefly immerse the surface of the plastic gear and preliminarily cool the plastic gear. Then, the electric winder 13 will raise the collecting box 14 to quickly separate the plastic gear inside the collecting box 14 from the cooling water, thereby reducing the excessive contact between the low-temperature cooling water and the plastic gear, which will cause the plastic gear material to expand and contract during the cooling process. The short low-temperature contact can greatly avoid the cracking of the plastic surface caused by the concentration of thermal stress caused by rapid temperature changes.

[0034] The surfaces on both sides of the rising aggregate box 14 will be aligned with the air pipe 117 and one end of the return air pipe 114. At this time, the inside of the air pipe 117 will be blown quickly by the blower 116, and the infused air will accumulate inside the aggregate box 14. The gas accumulated inside the aggregate box 14 will enter the inside of the condensation extractor 112 through the return air pipe 114. The closed surface of the aggregate box 14 allows the gas to enter the inside of the condensation extractor 112 only from the inside of the return air pipe 114, and the high-speed flowing gas will impact the plastic gears inside the aggregate box 14. In the process of impact, the water source remaining on the surface of the plastic gears will be cleaned away, so that the water source will be cleaned away under the push of the gas, reducing the residence time of water droplets on the surface of the plastic gears, and avoiding the effect of water spots on the surface of the plastic gears due to drying up of the water source;

[0035] In conjunction with the electric winder 13, the collection box 14 for collecting plastic gears is lowered deep inside the cooling box 12, and the low-temperature water source inside the cooling box 12 is used to contact the plastic gears inside the collection box 14, and the low-temperature water source is used to quickly cool down the plastic gears inside the collection box 14. At this time, the condensation extractor 112 is used to infuse water into the inside of the push water pipe 113, and the impact of the water source is used to stir the low-temperature water source inside the cooling box 12. The excess water source will be absorbed into the inside of the condensation extractor 112 through the return water pipe 111. The circulating flow of the water source will change the surface of the plastic gear to always remain in a low temperature state, and the temperature will not increase after the water source absorbs heat, thereby reducing the cooling effect.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
