Technical Field

[0001] The present application relates to the field of injection molding processing, and in particular to a cooling device for thin-cover plastic parts. Background Art

[0002] At present, plastics are common materials in life. Among the several plastic manufacturing processes, injection molding is widely used in plastic processing and manufacturing as a processing method with fast processing speed and convenient mass production. In the existing injection molding method for thin cover plastic parts, the injection molding raw materials after heating and melting are usually injected into the injection mold, and the molding is carried out after cooling, and then the mold is opened for demolding. After demolding, the thin cover plastic parts still have a high temperature. The thin cover plastic parts will be cooled to room temperature again before storage and transportation.

[0003] Regarding the above-mentioned related technologies, the commonly used cooling method is to spread out the thin cover plastic parts or cool them with fans, but the cooling rate is slow and the operation is complicated. Utility Model Content

[0004] In order to increase the cooling speed of a thin cover plastic part after demoulding, the present application provides a thin cover plastic part cooling device.

[0005] The present application provides a thin cover plastic cooling device, which adopts the following technical solution:

[0006] A thin cover plastic part cooling device comprises a shell, wherein the shell is provided with a plurality of cooling grooves, the depth of the cooling grooves is the same as the length of the thin cover plastic part, the cooling grooves are adapted to the thin cover plastic part, a cooling flow channel is provided inside the shell, the shell is provided with a water inlet and a water outlet, and the water inlet and the water outlet are both connected to the cooling flow channel.

[0007] By adopting the above technical scheme, when the thin cover plastic part is demoulded after injection molding, the thin cover plastic part is placed in the cooling tank. At this time, the thin cover plastic part is in close contact with the wall of the cooling tank, and the heat exchange between the thin cover plastic part and the shell is used to achieve the cooling effect of the thin cover plastic part. The heat of the shell is then taken away by the cooling water in the cooling channel, which effectively plays a role in quickly cooling the thin cover plastic part.

[0008] Optionally, the water inlet is located on the lower end surface of the shell, and the water outlet is located on a side of the upper end surface of the shell away from the water inlet.

[0009] By adopting the above technical solution, cooling water enters from the water inlet and is discharged from the water outlet at the upper end of the shell from bottom to top. By setting the water outlet on the side away from the water inlet, the cooling water fills the cooling channel, effectively discharges the air in the cooling channel, and improves the heat exchange efficiency between the cooling channel and the shell.

[0010] Optionally, the cooling channels are provided in several layers from top to bottom, and connecting channels are provided between the cooling channels in adjacent layers.

[0011] By adopting the above technical solution, the cooling channels are arranged in layers and the cooling channels of different layers are connected through connecting channels, so that the cooling channels are as close to the cooling groove as possible, and the contact area between the cooling water and the shell is effectively increased, thereby effectively improving the heat exchange efficiency of the cooling water.

[0012] Optionally, a plurality of springs are provided at the bottom of the cooling groove, one end of the spring away from the bottom of the groove is fixedly connected to a push plate, the edge of the push plate is slidably connected to the inner wall of the cooling groove, and the shell is provided with a cover plate for pressing the thin cover plastic part into the cooling groove.

[0013] By adopting the above technical solution, the thin cover plastic part is pressed into the cooling groove by using the cover plate. When taking out the thin cover plastic part, the cover plate is opened, and the thin cover plastic part placed in the cooling groove is pushed upward by the spring and the push plate, so that the thin cover plastic part can be taken out of the cooling groove easily.

[0014] Optionally, inclined grooves are provided at both ends of the opening side of the cooling groove.

[0015] By adopting the above technical solution, when the operator needs to take the thin cover plastic part out of the cooling tank, the operator can place his fingers along the inclined groove against both sides of the thin cover plastic part to lift the thin cover plastic part upward, which effectively facilitates the operator to take the thin cover plastic part out of the cooling tank.

[0016] Optionally, the shell is provided with a circulation system, the circulation system includes a circulation pump and a water tank, both ends of the circulation pump are respectively connected to the water tank and the water inlet, and the water outlet is connected to the water tank, a cooling fan is provided on the outside of the water tank, and a cooling copper pipe is provided between the cooling fan and the outer wall of the water tank.

[0017] By adopting the above technical solution, the circulation system circulates the cooling water in the cooling channel, pumps the cooling water with lower temperature in the water tank into the shell through the circulation pump, and dissipates heat from the water tank through the cooling fan, so that the cooling water circulated by the circulation pump always maintains a low temperature, and the cooling water is recycled under the premise of ensuring low cooling water temperature.

[0018] Optionally, the shell is provided with a plurality of detection holes, and temperature sensors are provided in the detection holes.

[0019] By adopting the above technical solution, the temperature sensor in the detection hole detects the shell temperature in real time. The average value of the temperatures measured by multiple temperature sensors can be used to more accurately obtain the shell temperature. The circulation speed of the circulation pump is controlled by temperature, thereby achieving control of the shell temperature.

[0020] Optionally, the side edge of the cooling groove opening is chamfered.

[0021] By adopting the above technical solution, when the operator places the thin cover plastic part into the cooling groove, the chamfer at the opening of the cooling groove guides the thin cover plastic part to be placed into the cooling groove, making it easier for the operator to place the thin cover plastic part into the cooling groove.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the thin cover plastic part is demoulded after injection molding, the thin cover plastic part is placed in the cooling tank. At this time, the thin cover plastic part is in close contact with the cooling tank wall. The heat exchange between the thin cover plastic part and the shell is used to achieve the cooling effect of the thin cover plastic part. The heat of the shell is taken away by the cooling water in the cooling channel, which effectively plays a role in the rapid cooling of the thin cover plastic part.

[0024] 2. After entering from the water inlet, the cooling water is discharged from the water outlet at the upper end of the shell from bottom to top. By setting the water outlet on the side away from the water inlet, the cooling water fills the cooling channel, effectively discharges the air in the cooling channel, and improves the heat exchange efficiency between the cooling channel and the shell.

[0028] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0029] The embodiment of the present application discloses a thin cover plastic part cooling device.

[0030] Reference Figure 1 and Figure 2A thin cover plastic cooling device includes a shell 1, the shell 1 is provided with a plurality of cooling grooves 2, the cooling grooves 2 and the thin cover plastic have the same profile, a cooling channel 15 is provided inside the shell 1, and the shell 1 is provided with a water inlet 12 and a water outlet 13, both of which are connected with the cooling channel 15. After the operator removes the thin cover plastic that has been completed by injection molding and demoulding from the injection molding machine, he puts it into the cooling groove 2. Since cooling water continuously flows through the cooling groove 2, the temperature in the cooling groove 2 is lower than the temperature of the thin cover plastic. Heat exchange is achieved through the contact between the inner wall of the cooling groove 2 and the thin cover plastic. After the heat is absorbed by the shell 1, it is taken away by the cooling water, so that the thin cover plastic is quickly cooled down, which is convenient for the subsequent packaging or storage of the thin cover plastic.

[0031] Reference Figure 1 In order to facilitate the operator to put the thin cover plastic part into the cooling tank 2, the edge of the opening side of the cooling tank 2 is provided with a chamfer 24. When the operator needs to put the thin cover plastic part into the cooling tank 2, the operator slightly tilts the thin cover plastic part and makes contact with the chamfer 24. At this time, the chamfer 24 guides the thin cover plastic part. This makes it easier for the operator to put the thin cover plastic part into the cooling tank 2.

[0032] Reference Figure 2 After the thin cover plastic part is placed in the cooling tank 2, the thin cover plastic part contacts the push plate 22 installed at the bottom of the tank. A number of springs 21 are installed between the push plate 22 and the bottom of the tank. The push plate 22 is slidably connected to the inner wall of the cooling tank 2. After the thin cover plastic part is placed, cover it with the cover plate 11. In this embodiment, the cover plate 11 is preferably connected to the housing 1 by a hinge. The cover plate 11 presses the thin cover plastic part into the cooling tank 2. When cooling is completed, the cover plate 11 is opened, and the push plate 22 pushes the thin cover plastic part upward, so that the operator can more easily take the thin cover plastic part out of the cooling tank 2.

[0033] Reference Figure 2 In order to further facilitate the operator to take out the thin cover plastic part, inclined grooves 23 are provided at both ends of the opening side of the cooling tank 2. When the push plate 22 pushes part of the thin cover plastic part out of the cooling tank 2, most of it is still in the cooling tank 2. At this time, the operator extends his fingers into the cooling tank 2 along the inclined grooves 23 at both ends of the cooling tank 2 to take the thin cover plastic part out of the cooling tank 2.

[0034] Reference Figure 1 and Figure 2In order to allow the cooling water to fill the entire cooling channel 15, the water inlet 12 is located on the lower end surface of the shell 1, and the water outlet 13 is located on the side of the upper end surface of the shell 1 away from the water inlet 12. According to the arrangement of the water inlet 12 and the water outlet 13 in this example, the cooling water first enters the cooling channel 15 through the lower water inlet 12, and then runs from bottom to top. After the cooling water fills the cooling channel 15 at the bottom, it flows upward and finally discharges the cooling channel 15 through the water outlet 13 above the shell 1. The process of cooling water flowing in the cooling channel 15 discharges the air in the cooling water channel from the upper water outlet 13, effectively realizing the discharge of the air in the cooling channel 15, thereby increasing the contact area between the cooling water and the inner wall of the cooling channel 15, thereby effectively increasing the heat exchange efficiency of the cooling water.

[0035] Reference Figure 1 and Figure 2 The cooling channel 15 is divided into several layers from top to bottom, and connecting channels are provided between adjacent cooling channels 15 to connect the cooling channels 15. After entering the cooling channel 15 from the water inlet 12 below the shell 1, it flows upward layer by layer, so that it flows from bottom to top, making the temperature inside the entire shell 1 more uniform.

[0036] Reference Figure 1 and Figure 2 In order to circulate water to the cooling channel 15, so that the cooling water in the cooling channel 15 always maintains a low temperature. Therefore, a circulation system 3 for cooling water circulation is installed on the outside of the shell 1. The circulation system 3 in this embodiment includes a circulation pump 32 and a water tank 31. The two ends of the circulation pump 32 are respectively connected to the water tank 31 and the water inlet 12, and the water outlet 13 is connected to the water tank 31. The cooling water in the water tank 31 is pumped into the water inlet 12 of the cooling channel 15 by the circulation pump 32 to realize water supply to the cooling channel 15. The cooling water discharged from the water outlet 13 returns to the water tank 31. The circulation of the cooling water in the cooling channel 15 is realized.

[0037] Reference Figure 1 A cooling fan 33 is provided outside the water tank 31, and a cooling copper pipe is provided between the cooling fan 33 and the outer wall of the water tank 31. The cooling copper pipe is cooled by the cooling fan 33 by being in close contact with the water tank 31, thereby cooling the cooling water in the water tank 31.

[0038] Reference Figure 1 A plurality of detection holes 14 are provided on the upper end surface of the housing 1, and temperature sensors are installed in the detection holes 14. The temperature of the housing 1 is detected by the temperature sensor, thereby realizing real-time monitoring of the temperature of the housing 1, so that the operator can adjust the working power of the circulation pump 32 and thus adjust the temperature of the housing 1.

[0039] The implementation principle of a thin cover plastic part cooling device in an embodiment of the present application is: cooling the thin cover plastic part through the cooling groove 2, dissipating heat to the shell 1 through the cooling channel 15, and cooling the cooling water inside the shell 1 through the circulation system 3.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
