Casing cooling plate

Abstract

The utility model provides a casing cooling plate which is characterized in that a first annular wall is arranged in a cooling groove with a material passing hole and divides the space in the cooling groove into a first space on the outer side and a second space on the inner side. The water injection pipe penetrates through the side wall of the cooling tank and the first space to be connected with the first annular wall so as to communicate with the water pump and the second space. The water injection speed of the water injection pipe is higher than the drainage speed of the material passing hole; therefore, when the second space is gradually filled with the cooling liquid, additional cooling liquid goes across the first annular wall to enter the first space, and a low-temperature area is formed in the first space. In this way, the cooling liquid in the first space and the cooling liquid in the second space are not directly communicated, the cooling liquid in the first space preferentially absorbs heat in the surrounding space, and the heat preservation effect on the cooling liquid in the second space is achieved; therefore, a better shock cooling effect on the casing film blank is ensured.

Description

Technical Field

[0003] Among them, in the quenching working condition, a coolant tray is required to quench the casing film blank. During use, low-temperature coolant needs to be injected into the coolant tray, and the inner hole of the water tray is for the casing film blank to pass through; as the casing film blank passes through the inner hole, the coolant flows out of the inner hole along with the casing film blank to quench and cool the casing film blank.

[0004] However, the existing coolant tray has poor heat preservation effect, resulting in the low-temperature coolant being more likely to absorb the heat of the surrounding space after injection, causing its temperature to rise; furthermore, when quenching and cooling the casing film blank, the effect is poor.

Detailed Embodiments

[0034] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the utility model are shown in the drawings.

[0035] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and embodiments.

[0036] Please refer to Figure 1-2 , the present utility model provides a casing cooling tray, comprising:

[0037] A cooling tank 1, a material passing hole 2 is opened at the bottom of the cooling tank 1 for the casing film blank 3 and the low-temperature coolant to pass through during the processing;

[0038] A first annular wall 4, the first annular wall 4 is arranged in the cooling tank 1, dividing the space in the cooling tank 1 into a first space between the first annular wall 4 and the side wall of the cooling tank 1 and a second space inside the first annular wall 4; the material passing hole 2 is communicated with the second space;

[0039] A water injection pipe 17, the water injection pipe 17 passes through the side wall of the cooling tank 1 and is connected to the first annular wall 4 for communicating the water pump with the second space;

[0040] The height of the first annular wall 4 is lower than the height of the side wall of the cooling tank 1; when the liquid level height in the second space is equal to the height of the first annular wall 4, the additional coolant crosses the first annular wall 4 and enters the first space;

[0041] The coolant in the second space is used to cool the casing film blank 3; the first space is used to inject and hold additional coolant to form a low-temperature zone in the first space.

[0042] Specifically, the coolant is water and the casing film blank 3 is in a molten state.

[0043] The water injection pipe 17 passes through the side wall of the cooling tank 1 and the first annular wall 4 to inject into the second space. The coolant is discharged from the material passing hole 2 along with the casing film blank 3, and heat exchange is carried out simultaneously to rapidly cool the casing film blank 3.

[0044] The injection speed of the coolant is greater than the discharge speed, so the liquid level of the coolant in the second space gradually rises until it is equal to the height of the first annular wall 4; at this time, the additional coolant will cross the first annular wall 4 and enter the first space, and finally a low-temperature zone is formed in the first space.

[0045] Further, the first annular wall 4 is made of a heat-insulating material.

[0046] After a low-temperature area is formed in the first space, the coolant in the first space preferentially absorbs the heat from the surrounding space, preventing the coolant in the second space from absorbing heat, resulting in a poor effect when quenching the casing film blank 3. At this time, since the first annular wall 4 is made of a heat-insulating material, it can ensure that the heat absorbed by the coolant in the first space will not be transferred to the coolant in the second space, playing a role in keeping the coolant in the second space warm and ensuring a good quenching effect on the casing film blank 3.

[0047] Further, a drain pipe 18 is connected to the side wall of the cooling tank 1 for discharging the excess coolant in the first space.

[0048] Specifically, the height of the drain pipe 18 is equal to the height of the first annular wall 4. When the liquid level height of the coolant in the first space does not reach the position where the drain pipe 18 is connected, no coolant will be discharged from the drain pipe 18; when the first space is filled with coolant and the liquid level height of the coolant reaches the position where the drain pipe 18 is connected, the excess coolant is discharged through the drain pipe 18, and a constant liquid level height is maintained in the first space.

[0049] Further, a second annular wall 5 made of a heat-insulating material is provided in the second space; the second annular wall 5 divides the second space into a third space between the second annular wall 5 and the first annular wall 4 and a fourth space inside the second annular wall 5; the material passing hole 2 communicates with the fourth space;

[0050] A plurality of first through holes 6 are formed in the second annular wall 5 for allowing the coolant to flow from the third space into the fourth space.

[0051] Specifically, before the casing film blank 3 comes into contact with the coolant, the following situation may occur: the casing film blank 3 dissipates heat through the air and is then absorbed by the coolant in the third space, resulting in a slow cooling situation rather than quenching.

[0052] Providing the second annular wall 5 with heat-insulating function in the second space can avoid the above situation and ensure that the casing film blank 3 is quenched when it comes into contact with the coolant.

[0053] Further, a flow buffering component 7 is installed in the fourth space;

[0054] The flow buffering component 7 includes:

[0055] A first sleeve 8 and a second sleeve 9, the second sleeve 9 is arranged inside the first sleeve 8; the internal space of the second sleeve 9 communicates with the material passing hole 2; the casing film blank 3 passes through the second sleeve 9 and enters the material passing hole 2;

[0056] A second through hole 10 is formed in the first sleeve 8, and a third through hole 11 is formed in the second sleeve 9; both the second through hole 10 and the third through hole 11 are for coolant to pass through.

[0057] Furthermore, the second through hole 10 and the third through hole 11 are arranged circumferentially offset along the first sleeve 8 and the second sleeve 9.

[0058] Specifically, the slow flow component 7 is provided to prevent the discharge speed of the coolant in the second space from being greater than the injection speed, resulting in the second space not being filled with the coolant and entering the first space; at the same time, the slower flow rate can allow the coolant to exchange heat with the casing film blank 3 more, promoting its rapid cooling.

[0059] The way that the second through hole 10 and the third through hole 11 on the slow flow component 7 are arranged offset from each other can make the coolant flow out of the material passing hole 2 more slowly, improving the heat exchange efficiency.

[0060] Furthermore, it further includes:

[0061] A refrigeration component, the refrigeration component is installed outside the bottom of the cooling tank 1; the casing film blank 3 sequentially passes through the material passing hole 2 and the refrigeration component; the refrigeration component is used to refrigerate the casing film blank 3 and the coolant flowing down with the casing film blank 3.

[0062] Furthermore, the refrigeration component includes:

[0063] A sealed housing 12, the sealed housing 12 is installed outside the bottom of the cooling tank 1; a fourth through hole 13 is formed in the sealed housing 12; the casing film blank 3 passes through the fourth through hole 13; the interior of the sealed housing 12 has a first installation space that is not communicated with both the fourth through hole 13 and the outside.

[0064] A refrigerator 14, the refrigerator 14 is arranged in the first installation space and is used to refrigerate the casing film blank 3 and the coolant.

[0065] Specifically, the refrigerator 14 uses a semiconductor refrigerator, which has the characteristics of no noise, no vibration, no need for refrigerant, small volume, light weight, etc., and is reliable in operation, simple to operate, and easy to adjust the cooling capacity. When the temperature of the casing film blank 3 is on the high side, the semiconductor refrigerator can refrigerate the casing film blank 3 to complete the rapid cooling process.

[0066] A sealed interlayer is provided inside the sealed housing 12 to prevent the coolant from coming into contact with the cooler 14 and causing a short circuit. After the coolant flowing out of the casing film blank 3 is cooled by the cooler 14, its temperature decreases, and it moves downward together with the casing film blank 3, continuously absorbing the heat of the casing film blank 3 and further improving the cooling effect.

[0067] Furthermore, there is a second installation space between the sealed housing 12 and the cooling tank 1; an insulating layer 15 is provided in the second installation space.

[0068] Specifically, the cooler 14 is installed outside the cooling tank 1 through the sealed housing 12. When the cooler 14 cools, it may cause the coolant in the cooling tank 1 to freeze, thereby hindering the coolant from flowing out of the material passing hole 2. When the installation position of the cooler 14 is directly opposite the flow buffering assembly 7, it may cause ice formation inside the flow buffering assembly 7.

[0069] Therefore, providing an insulating layer 15 between the cooler 14 and the cooling tank 1 can effectively prevent the cooler 14 from causing ice formation in the cooling tank 1 and blocking the material passing hole 2.

[0070] Furthermore, a temperature sensor 16 is also installed in the first installation space to detect the temperature of the casing film blank 3 before passing through the refrigeration assembly; and control the opening and closing of the cooler 14 according to the temperature of the casing film blank 3.

[0071] Specifically, the temperature sensor 16 is installed in the first installation space of the sealed housing 12 to detect the temperature of the casing film blank 3 cooled by the coolant through the temperature sensor 16.

[0072] When the temperature meets the processing requirements, there is no need to turn on the cooler 14 to continue cooling the casing film blank 3; when the temperature is higher than the processing requirements, the cooler 14 is turned on to continue cooling the casing film blank 3 so that the casing film blank 3 reaches the required temperature.

[0073] The above description is only the preferred embodiment of the present utility model and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present utility model is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model.
