[0002] Foaming molding is a commonly used processing technology for plastic parts. It involves dissolving gas in a liquid polymer or heating the polymer to a molten state, then forming numerous tiny bubble nuclei through nucleation, and finally expanding the bubble nuclei into a foam body with the required foam structure.

[0035] It should be noted that, without conflict, different features in the embodiments of the present application can be combined with each other.

[0036] After research by the inventor, it is found that in the foaming process of the refrigeration equipment box body, currently, a mechanical lifting rod structure or a fully pneumatic expansion and contraction structure is commonly used to drive the mold core. However, these two structures have obvious defects in the actual foaming process, resulting in problems such as box body deformation (such as bulging of the back and unevenness of the bile mouth) after foaming, which in turn affects the sealing performance of the refrigeration equipment and is prone to cold leakage, thus affecting the refrigeration effect of the refrigeration equipment. In addition, the currently commonly used cylinder ejection structure is complex in design and is not conducive to size adjustment and maintenance during the production process.

[0037] In view of this, this embodiment provides a solution that can solve the above problems, and the solution provided by this embodiment will be elaborated in detail below.

[0038] Please refer to Figure 1 , Figure 1Schematic structural diagram of the box foaming device provided in this embodiment. The box foaming device may include a mounting frame 100, a base 200, and a mold core 300.

[0039] The base 200 may be located on one side of the mounting frame 100.

[0040] In this embodiment, the base 200 may be used to mount the mold core 300, and the orthographic projection of the base 200 on the mounting frame 100 may completely cover the orthographic projection of the mold core 300 on the mounting frame 100.

[0041] Exemplarily, the shape of the base 200 may be a cuboid, and the size of the base 200 may be equal to the size of the mounting frame 100. For example, the length of the base 200 may be equal to the length of the mounting frame 100, and the width of the base 200 may also be equal to the width of the mounting frame 100.

[0042] The mold core 300 may be located on the side of the base 200 away from the mounting frame 100, and the mold core 300 may move in a direction perpendicular to the mounting frame 100.

[0043] In this embodiment, during the foaming process, the mold core 300 may be located inside the box 400 of the refrigeration device, and when subjected to the extrusion force of the foaming material, the mold core 300 may move in a direction close to the mounting frame 100.

[0044] Specifically, please refer to Figure 2 , the mold core 300 may include a top plate 310. During the foaming process, the mold core 300 may first be inserted into the box 400 of the refrigeration device, so that the mold core 300 is in a freely hanging state, and the distance between the top plate 310 of the mold core 300 and the inner liner is controlled to be less than 0.5 millimeters (mm). Then, the foaming material may be filled between the outer shell and the inner liner for foaming. The extrusion force generated by the foaming is used to squeeze the top plate 310 of the mold core 300 and the inner liner, driving the mold core 300 and the inner liner to float simultaneously, thereby reducing the distance between the mold core 300 and the inner liner and making the mold core 300 fit the inner liner, thus avoiding the problem of the back of the box 400 bulging.

[0045] In addition, the refrigeration device in this embodiment may be a freestanding refrigeration device or a combined refrigeration device that realizes synchronous refrigeration by multiple mutually separated refrigeration compartments. Exemplarily, the refrigeration device may be a refrigerator, a freezer, etc.

[0046] It can be seen that based on the above design, the box foaming device provided in this embodiment can use the extrusion force generated during foaming to drive the mold core 300 to move in a direction perpendicular to the mounting frame 100, thereby effectively avoiding the deformation of the box during the foaming process and ensuring the sealing performance and refrigeration effect of the refrigeration device.

[0047] In one possible implementation, please refer toFigure 3 The box body foaming device may further include a first movable component 510 and a first fixing component 610. The mold core 300 and the base 200 may be movably connected through the first movable component 510, and the base 200 and the mounting frame 100 may be fixedly connected through the first fixing component 610.

[0048] In this embodiment, there may be a gap between the mold core 300 and the base 200. The mold core 300 may be movably connected to the base 200, and the first movable component 510 may drive the mold core 300 to move in a direction perpendicular to the plane where the base 200 is located. There is no gap between the base 200 and the mounting frame 100. The base 200 and the mounting frame 100 may be tightly fixed through the first fixing component 610 to ensure the stability of the overall structure.

[0049] During the foaming process, the foaming material may apply an upward extrusion force to the mold core 300 and the inner liner, driving the mold core 300 to float together with the inner liner, causing the mold core 300 to move upward relative to the base 200, thereby reducing the gap between the base 200 and the mold core 300 and avoiding the problem of uneven box body nozzle.

[0050] The base 200 is provided with a first fixing hole, and the mounting frame 100 is provided with a second fixing hole. The first fixing component 610 may pass through the first fixing hole and the second fixing hole to achieve the fixed connection between the base 200 and the mounting frame 100.

[0051] Specifically, the base 200 may be provided with a plurality of first fixing holes, and the mounting frame 100 may be provided with a plurality of second fixing holes. The number of the first fixing holes and the second fixing holes is equal. The sizes of the plurality of first fixing holes and the plurality of second fixing holes are the same and their positions correspond. The plurality of first fixing holes and the plurality of second fixing holes may be evenly distributed. The box body foaming device may also include a plurality of first fixing components 610, and the number of the first fixing components 610 may be equal to the number of the first fixing holes and the second fixing holes. The plurality of first fixing components 610 may respectively pass through the plurality of first fixing holes and the plurality of second fixing holes to achieve the tight connection between the base 200 and the mounting frame 100. In this way, by setting a plurality of first fixing holes and a plurality of second fixing holes, not only the connection stability between the base 200 and the mounting frame 100 can be improved, but also a stable support can be provided when the mold core 300 floats.

[0052] The sizes and shapes of the first fixing hole and the second fixing hole can match the sizes and shapes of the first fixing member 610. The shapes of the first fixing hole and the second fixing hole can include circular, square, diamond, etc. Specifically, when the shapes of the first fixing hole and the second fixing hole are circular, the shape of the first fixing member 610 can be cylindrical, and the sizes of the first fixing hole and the second fixing hole can be the diameters of the circles, and the size of the first fixing member 610 can be the diameter of the cylinder; when the shapes of the first fixing hole and the second fixing hole are square, the shape of the first fixing member 610 can be cuboid, and the sizes of the first fixing hole and the second fixing hole can be the side lengths of the squares, and the size of the first fixing member 610 can be the side length of the cuboid.

[0053] It can be understood that the shapes of the first fixing hole and the second fixing hole may not match the shape of the first fixing member 610. For example, the shape of the first fixing member 610 can be cylindrical, while the shape of the first fixing hole can be rectangular or oval, and the size of the first fixing hole can be larger than the size of the first fixing member 610. In this way, not only can the fixed connection between the base 200 and the mounting bracket 100 be achieved, but also the relative position of the mold core 300 can be adjusted in the direction parallel to the plane where the mounting bracket 100 is located, facilitating the mold core 300 to extend into the box body 400.

[0054] Exemplarily, the first fixing member 610 can be a screw (e.g., M6 screw), and the first fixing hole and the second fixing hole can be threaded holes.

[0055] It should be noted that the first fixing member 610 is not limited to screws, and can also be other fixing members, such as bolts, rivets, etc., as long as the firm connection between the base 200 and the mounting bracket 100 can be achieved.

[0056] In the above design, the mold core 300 and the base 200 can be movably connected through the first movable component 510, so that the mold core 300 can flexibly respond to the change of extrusion pressure during the foaming process, thereby effectively avoiding the deformation of the box body, ensuring the sealing performance, and improving the refrigeration effect.

[0057] In a possible implementation manner, the mold core 300 is provided with a first connection hole, the base 200 is provided with a second connection hole, and the first movable component 510 can pass through the second connection hole and be fixed to the first connection hole. The first movable component 510 can drive the mold core 300 to move in a direction perpendicular to the base 200.

[0058] In this embodiment, the first movable component 510 can pass through the second connection hole and be fixedly connected to the first connection hole. When the foaming material in the box body 400 expands, it can generate an extrusion force on the mold core 300. Since the first movable component 510 is fixed to the first connection hole and the first movable component 510 can move up and down relative to the second connection hole, the extrusion force generated by the expansion of the foaming material can drive the mold core 300 and the first movable component 510 to move upward, thereby reducing the distance between the mold core 300 and the base 200.

[0059] Specifically, the mold core 300 can be provided with a plurality of first connection holes, and the base 200 can be provided with a plurality of second connection holes. The number of the first connection holes is equal to that of the second connection holes, and the plurality of first connection holes and the plurality of second connection holes correspond to each other respectively; the box body foaming device can also include a plurality of first movable components 510, and the number of the first movable components 510 can be equal to the number of the first connection holes and the second connection holes. The plurality of first movable components 510 can respectively pass through the plurality of first connection holes and the plurality of second connection holes to realize the movable connection between the base 200 and the mold core 300.

[0060] It can be understood that the shapes of the first connection hole and the second connection hole can match the shape of the first movable component 510, and the sizes of the first connection hole and the second connection hole can match the size of the first movable component 510. The shapes of the first connection hole and the second connection hole can include a circle, a square, a rhombus, etc. If the size of the first movable component 510 is 14 millimeters (mm), the size of the first connection hole can be 14.01 millimeters (mm), and the size of the second connection hole can be 14.02 millimeters (mm). When the shape of the first movable component 510 is cylindrical and the first connection hole and the second connection hole are circular, the size of the first movable component 510 is its diameter, and the sizes of the first connection hole and the second connection hole are also their diameters.

[0061] Exemplarily, the first movable component 510 can be a self-floating screw (for example, an M14 screw).

[0062] It should be noted that the first movable component 510 is not limited to a screw, and can also be other movable components, such as bolts, rivets, etc., as long as the movable connection between the base 200 and the mold core 300 can be realized.

[0063] In a possible implementation manner, the length of the first movable component 510 can be greater than the sum of the lengths of the first connection hole and the second connection hole.

[0064] In this embodiment, the difference range between the length of the first movable component 510 and the sum of the lengths of the first connection hole and the second connection hole can be from 1 millimeter (mm) to 5 millimeters (mm). Exemplarily, the difference between the length of the first movable component 510 and the sum of the lengths of the first connection hole and the second connection hole can include 1 millimeter (mm), 1.5 millimeters (mm), 1.6 millimeters (mm), 2 millimeters (mm), 2.4 millimeters (mm), 2.8 millimeters (mm), 3 millimeters (mm), 3.1 millimeters (mm), 4 millimeters (mm), and 5 millimeters (mm), etc. Preferably, the difference between the length of the first movable component 510 and the sum of the lengths of the first connection hole and the second connection hole is 3 millimeters (mm). In this way, when connecting the mold core 300 and the base 200 through the first movable component 510, a gap can be ensured between the mold core 300 and the base 200, facilitating driving the mold core 300 to move in the direction close to the base 200 during the foaming process.

[0065] In a possible implementation manner, please refer to Figure 4 , the box body foaming device may further include a second movable component 520 and a second fixing member 620. The base 200 and the mounting frame 100 may be movably connected through the second movable component 520, and the base 200 and the mold core 300 may be fixedly connected through the second fixing member 620.

[0066] In this embodiment, there may be a gap between the base 200 and the mounting frame 100. The base 200 may be movably connected to the mounting frame 100, and the second movable component 520 may drive the base 200 to move in a direction perpendicular to the plane where the mounting frame 100 is located. There may be no gap between the base 200 and the mold core 300. The base 200 and the mounting frame 100 may be tightly fixed through the second fixing member 620 to ensure the stability of the overall structure.

[0067] During the foaming process, the foaming material may exert an upward extrusion force on the mold core 300 and the inner liner, driving the mold core 300 to float together with the inner liner, causing the mold core 300 and the base 200 to move upward relative to the mounting frame 100, thereby reducing the gap between the base 200 and the mounting frame 100 and avoiding the problem of uneven box body bile openings.

[0068] The mold core 300 is provided with a third fixing hole, and the base 200 is provided with a fourth fixing hole. The second fixing member 620 may pass through the third fixing hole and the fourth fixing hole to achieve the fixed connection between the mold core 300 and the base 200.

[0069] Specifically, the mold core 300 can be provided with a plurality of third fixing holes, and the base 200 can be provided with a plurality of fourth fixing holes. The number of the third fixing holes and the fourth fixing holes is equal. The sizes of the plurality of third fixing holes and the plurality of fourth fixing holes are the same and the positions correspond to each other. The plurality of third fixing holes and the plurality of fourth fixing holes can be evenly distributed. The box body foaming device can also include a plurality of second fixing members 620, and the number of the second fixing members 620 can be equal to the number of the third fixing holes and the fourth fixing holes. The plurality of second fixing members 620 can respectively pass through the plurality of third fixing holes and the plurality of fourth fixing holes to achieve a firm connection between the mold core 300 and the base 200. In this way, by providing the plurality of third fixing holes and the plurality of fourth fixing holes, not only can the connection stability between the base 200 and the mold core 300 be improved, but also stable support can be provided when the mold core 300 floats.

[0070] The sizes and shapes of the third fixing holes and the fourth fixing holes can match the sizes and shapes of the second fixing members 620. The shapes of the third fixing holes and the fourth fixing holes can include circles, squares, rhombuses, etc. Specifically, when the shapes of the third fixing holes and the fourth fixing holes are circular, the shapes of the second fixing members 620 can be cylindrical, and the sizes of the third fixing holes and the fourth fixing holes can be the diameters of the circles, and the sizes of the second fixing members 620 can be the diameters of the cylinders; when the shapes of the third fixing holes and the fourth fixing holes are square, the shapes of the second fixing members 620 can be cuboid-shaped, and the sizes of the third fixing holes and the fourth fixing holes can be the side lengths of the squares, and the sizes of the second fixing members 620 can be the side lengths of the cuboids.

[0071] It can be understood that the shapes of the third fixing holes and the fourth fixing holes may not match the shapes of the second fixing members 620. For example, the shapes of the second fixing members 620 can be cylindrical, while the shapes of the third fixing holes can be rectangular or elliptical, and the sizes of the third fixing holes can be larger than the sizes of the second fixing members 620. In this way, not only can the fixed connection between the base 200 and the mold core 300 be achieved, but also the relative position of the mold core 300 can be adjusted in the direction parallel to the plane where the base 200 is located, which is convenient for the mold core 300 to extend into the box body 400.

[0072] Exemplarily, the second fixing members 620 can be screws (for example, M6 screws), and the third fixing holes and the fourth fixing holes can be threaded holes.

[0073] It should be noted that the second fixing members 620 are not limited to screws, and can also be other fixing members, such as bolts, rivets, etc., as long as the firm connection between the base 200 and the mold core 300 can be achieved.

[0074] In the above design, the mounting bracket 100 and the base 200 can be movably connected through the second movable component 520, and the base 200 and the die core 300 can be fixedly connected through the second fixing member 620, so that the die core 300 can flexibly respond to the change of extrusion pressure during the foaming process, effectively avoiding the deformation of the box body, ensuring the sealing performance, and improving the refrigeration effect.

[0075] In a possible implementation manner, the base 200 is provided with a third connection hole, the mounting bracket 100 is provided with a fourth connection hole, the second movable component 520 passes through the fourth connection hole and is fixed to the third connection hole, and the second movable component 520 can drive the base 200 to move in a direction perpendicular to the mounting bracket 100.

[0076] In this embodiment, the second movable component 520 can pass through the fourth connection hole and be fixedly connected to the third connection hole. When the foaming material in the box body 400 expands, it can generate an extrusion pressure on the die core 300. Since the die core 300 is fixedly connected to the base 200, the die core 300 will also generate an extrusion pressure on the base 200. Therefore, the extrusion pressure generated by the expansion of the foaming material can drive the die core 300 and the base 200 to move upward, and the second movable component 520 will also slide upward relative to the fourth connection hole, thereby reducing the distance between the base 200 and the mounting bracket 100.

[0077] Specifically, the base 200 can be provided with a plurality of third connection holes, the mounting bracket 100 can be provided with a plurality of fourth connection holes, the number of the third connection holes and the fourth connection holes is equal, and the plurality of third connection holes and the plurality of fourth connection holes correspond to each other; the box body foaming device can also include a plurality of second movable components 520, and the number of the second movable components 520 can be equal to the number of the third connection holes and the fourth connection holes. The plurality of second movable components 520 can respectively pass through the plurality of third connection holes and the plurality of fourth connection holes to realize the movable connection between the base 200 and the mounting bracket 100.

[0078] It can be understood that the shapes of the third connection hole and the fourth connection hole can match the shape of the second movable component 520, and the sizes of the third connection hole and the fourth connection hole can match the size of the second movable component 520. The shapes of the third connection hole and the fourth connection hole can include a circle, a square, a rhombus, etc. If the size of the second movable component 520 is 14 millimeters (mm), the size of the third connection hole can be 14.01 millimeters (mm), and the size of the fourth connection hole can be 14.02 millimeters (mm). When the shape of the second movable component 520 is cylindrical and the third connection hole and the fourth connection hole are circular, the size of the second movable component 520 is its diameter, and the sizes of the third connection hole and the fourth connection hole are also their diameters.

[0079] Exemplarily, the second movable component 520 can be a self-floating screw (for example, an M14 screw).

[0080] It should be noted that the second movable component 520 is not limited to screws, and can also be other movable components, such as bolts, rivets, etc., as long as the movable connection between the base 200 and the mounting frame 100 can be achieved.

[0081] In a possible implementation, the length of the second movable component 520 can be greater than the sum of the lengths of the third connection hole and the fourth connection hole.

[0082] In this embodiment, the difference range between the length of the second movable component 520 and the sum of the lengths of the third connection hole and the fourth connection hole can be from 1 millimeter (mm) to 5 millimeters (mm). Exemplarily, the difference between the length of the second movable component 520 and the sum of the lengths of the third connection hole and the fourth connection hole can include 1 millimeter (mm), 1.5 millimeters (mm), 1.6 millimeters (mm), 2 millimeters (mm), 2.4 millimeters (mm), 2.8 millimeters (mm), 3 millimeters (mm), 3.1 millimeters (mm), 4 millimeters (mm), and 5 millimeters (mm), etc. Preferably, the difference between the length of the second movable component 520 and the sum of the lengths of the third connection hole and the fourth connection hole is 3 millimeters (mm). In this way, when the mold core 300 is connected to the base 200 through the second movable component 520, a gap can be ensured between the mold core 300 and the base 200, facilitating the driving of the mold core 300 to move in the direction close to the base 200 during the foaming process.

[0083] In a possible implementation, please refer to again Figure 3 and Figure 4 , the box body foaming device can also include a gasket 700. The gasket 700 can be sleeved on the first movable component 510 or the second movable component 520, and the gasket 700 can be used to adjust the distance between the mold core 300 and the mounting frame 100.

[0084] In a possible implementation manner, when the mold core 300 is movably connected to the base 200 and the base 200 is fixedly connected to the mounting frame 100, the gasket 700 can be located above the base 200, and the first movable component 510 can sequentially pass through the gasket 700 and the second connection hole to be fixed to the first connection hole. By setting the gasket 700, the distance between the mold core 300 and the base 200 can be adjusted.

[0085] Specifically, the spacer 700 is detachably disposed on the first movable component 510. When it is necessary to reduce the distance between the mold core 300 and the base 200, the spacer 700 can be replaced, or the number of spacers 700 can be adjusted. For example, when it is necessary to reduce the distance between the mold core 300 and the base 200 by 0.1 mm, the spacer 700 with a thickness of 0.2 mm can be used to replace the spacer 700 with a thickness of 0.1 mm, or an additional spacer 700 with a thickness of 0.1 mm can be sleeved on the first movable component 510. Among them, the material of the spacer 700 can be steel.

[0086] Specifically, the spacer 700 can be annular, the first movable component 510 can be a screw, and the inner diameter of the spacer 700 can be larger than the outer diameter of the first movable component 510 to avoid uneven extrusion pressure during foaming.

[0087] In another possible implementation, when the mounting frame 100 is movably connected to the base 200 and the base 200 is fixedly connected to the mold core 300, the spacer 700 can be located above the mounting frame 100, and the second movable component 520 can pass through the spacer 700 and the fourth connection hole in sequence to be fixed to the third connection hole. By setting the spacer 700, the distance between the mounting frame 100 and the base 200 can be adjusted.

[0088] Specifically, the spacer 700 is detachably disposed on the second movable component 520. When it is necessary to reduce the distance between the mounting frame 100 and the base 200, the spacer 700 can be replaced, or the number of spacers 700 can be adjusted. For example, when it is necessary to reduce the distance between the mounting frame 100 and the base 200 by 0.1 mm, the spacer 700 with a thickness of 0.2 mm can be used to replace the spacer 700 with a thickness of 0.1 mm, or an additional spacer 700 with a thickness of 0.1 mm can be sleeved on the second movable component 520. Among them, the material of the spacer 700 can be steel.

[0089] Specifically, the spacer 700 can be annular, the second movable component 520 can be a screw, and the inner diameter of the spacer 700 can be larger than the outer diameter of the second movable component 520 to avoid uneven extrusion pressure during foaming.

[0090] In a possible implementation, please refer to Figure 5 , the box body foaming device can further include a limiting member 800. The mounting frame 100 can include a first limiting hole, the base 200 can include a second limiting hole, the mold core 300 can include a third limiting hole, and the limiting member 800 can pass through the first limiting hole, the second limiting hole and the third limiting hole to realize the limitation of the mold core 300.

[0091] In this embodiment, the length of the limiting member 800 can be greater than the lengths of the first limiting hole and the second limiting hole. The limiting member 800 can be used to limit the movement of the mold core 300 in a direction parallel to the plane where the mounting frame 100 is located, so that the mold core 300 can only move in a direction perpendicular to the plane where the mounting frame 100 is located, avoiding the deviation of the mold core 300 during the floating process. Among them, the limiting member 800 can be a positioning pin.

[0092] In addition, when it is necessary to adjust the position of the mold core 300 in a direction parallel to the plane where the mounting frame 100 is located, the limiting member 800 can be removed first and then the adjustment can be made.

[0093] The embodiment of the present application also provides a method for foaming a box body. The method for foaming a box body can use the box body foaming device provided in this embodiment. Please refer to Figure 6 , and the method for foaming a box body can include the following steps.

[0094] Step S110, placing the mold core 300 into the box body 400 of the refrigeration device.

[0095] Step S120, filling the box body 400 with a foaming material for foaming to apply pressure to the mold core 300, so that the mold core 300 moves in a direction perpendicular to the mounting frame 100.

[0096] In this embodiment, the actual sag amount of the mold core 300 can be adjusted by the gasket 700 so that the mold core 300 extends into the box body 400 of the refrigeration device. Then, a foaming material is filled into the box body 400 for foaming, and the extrusion force generated by the foaming expansion is used to drive the mold core 300 to move upward, thereby reducing the distance between the mold core 300 and the inner liner.

[0097] In summary, the embodiment of the present application provides a box body foaming device and method, which can use the extrusion force generated during foaming to drive the mold core to move in a direction perpendicular to the mounting frame, thereby effectively avoiding the deformation of the box body during the foaming process and ensuring the sealing performance and refrigeration effect of the refrigeration device.
