Description

Technical Field

[0001] This utility model relates to the technical field of cooling devices, and more specifically, to a system for cooling injection molded parts before receiving them. Background Technology

[0002] In modern manufacturing, injection molding is a very common method of parts production, widely used in various fields. Its working principle involves injecting molten plastic or rubber into a mold cavity under high pressure, where it cools and solidifies to obtain a plastic product with a specific shape and size. This production process has significant advantages such as high efficiency, large-scale production capability, and the ability to manufacture complex-shaped parts.

[0003] However, because injection molded parts retain their high temperature upon ejection from the injection molding machine, especially for larger parts, heat dissipation is slow and the cooling process is extremely time-consuming. This slow cooling rate directly impacts subsequent processing steps, severely hindering production efficiency. Furthermore, after demolding, collisions between injection molded parts and between the parts and the material runner are inevitable as they are conveyed along the runner. These collisions easily leave scratches, dents, and other damage on the workpiece surface, significantly reducing yield and increasing production costs. Therefore, a device can be designed that can both cool the injection molded parts and reduce collision damage. Utility Model Content

[0004] The purpose of this invention is to provide a system for cooling injection molded parts before receiving them, which can both cool the injection molded parts and reduce collision damage to the injection molded parts.

[0005] This utility model is achieved through the following technical solution: The system for cooling injection molded parts before receiving includes multiple horizontally arranged cooling devices, multiple horizontally arranged partitions, a support device for supporting the cooling devices, an air supply device connected to the cooling devices, and a driving device for driving the partitions to move horizontally; the cooling devices include horizontally arranged cooling plates, a cooling cavity opened inside the lower side of the cooling plates, and multiple discharge holes opened on the cooling plates; the air supply device communicates with the cooling cavity, the discharge holes are arranged through the cooling plates, and the multiple cooling plates are evenly distributed in the vertical direction; the partitions are provided with multiple through holes, one through hole corresponding to one discharge hole; the multiple cooling plates are distributed in the vertical direction, and one partition is located under one of the cooling plates.

[0006] Furthermore, the cooling device also includes a plurality of air guide pipes disposed in the cooling chamber, and a plurality of air vents opened on the side wall of the air guide pipes; one of the air guide pipes is disposed at one of the discharge holes.

[0007] Furthermore, the upper surface of the partition plate is attached to the lower surface of the cooling plate; a gap is provided between the lower surface of the partition plate and the upper surface of the cooling plate.

[0008] Furthermore, the upper surface of the partition plate is a smooth surface.

[0009] Furthermore, the air supply device includes an air compressor and a plurality of air pressure pipes connected to the air outlet of the air compressor; one of the air pressure pipes is connected to one of the cooling chambers.

[0010] Furthermore, the support device includes a base plate horizontally disposed below the cooling plate, and a plurality of support rods vertically disposed on the base plate; the support rods are also fixedly connected to the side walls of the plurality of cooling plates.

[0011] Furthermore, the support device also includes a pad that is horizontally fixed to the side wall of the support rod; the partition located at the bottom is slidably disposed on the pad.

[0012] Furthermore, the driving device includes a support plate vertically mounted on the base plate, a pair of telescopic cylinders mounted on the support plate, and a pair of vertically mounted connecting plates; one of the connecting plates is connected to the movable end of one of the telescopic cylinders, and adjacent partitions are fixedly connected to different connecting plates.

[0013] Furthermore, the telescopic cylinder is one of a pneumatic cylinder, an electric push rod, or a hydraulic cylinder.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: In the system for cooling injection-molded parts before receiving the material, the freshly injection-molded part is placed into the discharge hole of the cooling plate of the cooling device. After entering the discharge hole, the part is blocked by the lower partition. At this time, the air supply device sends room temperature air or cold air into the cooling chamber, and the room temperature air or cold air in the cooling chamber blows air to cool the part in the discharge hole. After the part briefly rests on the partition, the driving device drives the partition to move a distance equal to the length of a through hole. At this time, the through holes on the partition align with the discharge holes on the cooling plate, and the part can pass through the through holes into the next layer of cooling plates, where the cooling operation continues. In this way, the part passes through multiple cooling devices in sequence, ensuring thorough cooling. Furthermore, the multiple drops of the part result in a very low drop height each time, effectively reducing the probability of surface damage during the drop process and improving the yield rate of the parts.

Detailed Implementation

[0017] Example The following description, in conjunction with specific embodiments, further illustrates the points, as shown in the appendix. Figure 1 -Appendix Figure 9As shown, the system for cooling injection molded parts before receiving materials in this embodiment includes multiple horizontally arranged cooling devices 10, multiple horizontally arranged partitions 20, a support device 30 for supporting the cooling devices 10, an air supply device connected to the cooling devices 10, and a drive device 22 for driving the partitions 20 to move horizontally. The cooling devices 10 include horizontally arranged cooling plates 11, cooling chambers 12 opened inside the lower side of the cooling plates 11, and multiple discharge holes 13 opened on the cooling plates 11. The air supply device is connected to the cooling chambers 12, and the discharge holes 13 are arranged through the cooling plates 11. The multiple cooling plates 11 are evenly distributed in the vertical direction. Multiple through holes 21 are opened on the partitions 20, and one through hole 21 corresponds to one discharge hole 13. The multiple cooling plates 11 are distributed in the vertical direction, and one partition 20 is located under one cooling plate 11. Specifically, during use, the freshly injection-molded part is placed into the discharge hole 13 of the cooling plate 11 of the cooling device 10. After the part enters the discharge hole 13, it is blocked by the partition below. At this time, the air supply device sends room temperature air or cold air into the cooling chamber 12, and the room temperature air or cold air in the cooling chamber 12 blows air to cool the part in the discharge hole 13. After the part briefly stays on the partition 20, the driving device 22 drives the partition 20 to move a distance of one through hole 21. At this time, the through hole 21 is aligned with the discharge hole 13, and the part can pass through the through hole 21 into the next layer of cooling plate 11, where the cooling operation continues. In this way, the part passes through multiple cooling devices 10 in sequence, which can be fully cooled. Furthermore, the part is dropped multiple times, and the drop height is very low each time. This can effectively reduce the probability of surface damage caused by the part during the drop process and improve the yield of the part.

[0018] The cooling device 10 in this embodiment also includes a plurality of air guide pipes 14 disposed in the cooling chamber 12, and a plurality of vent holes 15 opened on the side wall of the air guide pipes 14; one air guide pipe 14 is disposed at one discharge hole 13. Specifically, the air guide pipe 14 is disposed at the connection between the cooling chamber 12 and the discharge hole 13, which can effectively prevent parts from getting stuck in the cooling chamber 12.

[0019] In this embodiment, the upper surface of the partition 20 is attached to the lower surface of the cooling plate 11; a gap is provided between the lower surface of the partition 20 and the upper surface of the cooling plate 11. Specifically, when room temperature air or cold air enters the cooling chamber 12, and then passes through the vent 15 on the side wall of the air guide pipe 14 into the discharge hole 13, the air will be discharged from the upper end of the discharge hole 13 as much as possible because the lower end of the discharge hole 13 is in close contact with the partition 20.

[0020] In this embodiment, the upper surface of the partition 20 is a smooth surface. Specifically, this reduces friction between the partition 20 and the part when the partition 20 moves, effectively preventing the part from getting stuck in the gap between the partition 20 and the cooling plate 11.

[0021] The air supply device in this embodiment includes an air compressor and multiple air pressure pipes 16 connected to the air outlet of the air compressor; one air pressure pipe 16 is connected to a cooling chamber 12. Specifically, the air compressor delivers air evenly into the multiple cooling chambers 12 through the air pressure pipes 16, and after rinsing and cooling the workpiece in the discharge hole 13, it is discharged from the upper end of the discharge hole 13.

[0022] The support device 30 in this embodiment includes a base plate 31 horizontally disposed below the cooling plate 11, and a plurality of support rods 32 vertically disposed on the base plate 31; the support rods 32 are simultaneously fixedly connected to the side walls of the plurality of cooling plates 11. Specifically, since the parts will fall onto the base plate 31 after being discharged from the lowest cooling plate 11, a conveyor belt needs to be laid on the base plate 31 to carry the parts away. Furthermore, the support rods 32 are simultaneously connected to the plurality of cooling plates 11, allowing for simultaneous support of the plurality of cooling plates 11.

[0023] The support device 30 in this embodiment also includes a pad 33 horizontally fixed to the side wall of the support rod 32; the lowest partition 20 is slidably disposed on the pad 33. Specifically, the main function of the pad 33 is to support the lowest partition 20.

[0024] The driving device 22 in this embodiment includes a support plate 221 vertically mounted on the base plate 31, a pair of telescopic cylinders 222 mounted on the support plate 221, and a pair of vertically mounted connecting plates 223. One connecting plate 223 is connected to the movable end of one telescopic cylinder 222, and adjacent partitions 20 are fixedly connected to different connecting plates 223. Specifically, the through holes 21 on adjacent partitions 20 in the vertical direction are staggered, and adjacent partitions 20 do not move simultaneously, but at intervals of a certain time, so that the parts are sufficiently stable.

[0025] In this embodiment, the telescopic cylinder 222 is one of a pneumatic cylinder, an electric push rod, or a hydraulic cylinder.

[0026] In summary, the system for cooling injection-molded parts before receiving them in this embodiment involves placing the freshly injection-molded part into the discharge hole 13 of the cooling plate 11 of the cooling device 10. Once inside the discharge hole 13, the part is blocked by the lower partition. At this time, the air supply device delivers ambient or cold air into the cooling chamber 12, which then blows air onto the part in the discharge hole 13 for cooling. After the part briefly rests on the partition 20, the driving device 22 moves the partition 20 a distance equal to the length of a through hole 21. The through hole 21 aligns with the discharge hole 13, allowing the part to pass through and enter the next cooling plate 11 for further cooling. This process, where the part passes through multiple cooling devices 10, ensures thorough cooling. Furthermore, the multiple drops of the part minimize the drop height, effectively reducing the probability of surface damage during the fall and improving the yield rate.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
