Description

Technical Field

[0001] The utility model relates to the technical field of foaming, in particular to a foaming pressing device and an electrical appliance box. Background Art

[0002] In the field of modern electrical appliance manufacturing, the installation and fixation of electrical box components are key links to ensure the performance and stability of the entire electrical appliance. Electrical box components are usually installed inside the entire machine. In order to prevent vibration during use of the electrical box and reduce the noise generated by internal wiring components, the side walls of an existing electrical box are made into a cavity structure. Multiple small holes are opened on the side walls of this electrical box and foam filling is performed to enhance the structural stability and sound insulation effect of the electrical box. However, there are some limitations in the foam filling process of this electrical box: due to the large number of small holes on the electrical box, the foam material needs to be compressed to prevent overflow, but the electrical box usually has only one-sided opening, which makes the compression operation difficult. The traditional solution is to use a large amount of masking paper to wrap and wrap the electrical box to achieve the compression effect. Although this method can solve the problem to a certain extent, it has obvious disadvantages: first, it is time-consuming, affecting production efficiency; second, it is labor-intensive and requires high physical strength from the operators; finally, since a large amount of masking tape is required, the cost is high, which is not conducive to cost control and environmental protection; and the viscosity and fit of masking tape are limited, making it difficult to ensure that all small holes can be tightly compressed, which may cause the foam material to overflow during the filling process, affecting the quality and performance of the product.

[0003] Therefore, it is necessary to improve the foaming process of the existing electrical box to overcome the defects of the prior art. Utility Model Content

[0004] In order to overcome the problems existing in the related art, one of the purposes of the present invention is to provide a foaming and pressing device, which can use a second pressing plate and a first pressing plate to press the product to be foamed, thereby avoiding the tedious steps of manually wrapping masking tape on the product, thereby improving the foaming efficiency and ensuring the foaming quality.

[0005] A foaming and pressing device comprises a base; a first pressing plate and a second pressing plate are provided on the base, wherein the first pressing plate is provided on the base, and the second pressing plate is movably provided on one side of the first pressing plate, and a pressing station for placing a product to be foamed is formed between the second pressing plate and the first pressing plate;

[0006] A driving device is fixed on the base, and the driving device drives the second pressing plate to move so that the second pressing plate approaches or moves away from the first pressing plate.

[0007] In actual applications, the drive device can be an electric, pneumatic or hydraulic drive device, and the most appropriate power source can be selected according to needs. The drive device can be connected to the second pressing plate through a connecting rod mechanism to ensure that the second pressing plate can accurately approach or move away from the first pressing plate. During the foaming and pressing process, the product to be foamed is first placed on the pressing station between the first pressing plate and the second pressing plate. Subsequently, the drive device is started, and the second pressing plate begins to move toward the first pressing plate until the two pressing plates are in close contact with the product to be foamed to achieve compression. The pressing force can be precisely controlled by adjusting the stroke or pressure of the drive device to meet the foaming requirements of different products. After the foaming process is completed, the drive device is started again to move the second pressing plate away from the first pressing plate, thereby releasing the compressed product. In this way, the foaming and pressing device can be ready for the next product to be foamed.

[0008] This foaming and pressing device eliminates the tedious step of manually wrapping masking tape through an automated pressing process, significantly improving foaming efficiency and reducing production cycle time. Furthermore, the drive mechanism precisely controls the pressing force and duration, ensuring uniform and appropriate pressure on the foamed product during the foaming process, thus guaranteeing foaming quality. This device also reduces the use of masking tape and manual labor, helping to reduce production costs while improving material utilization.

[0009] In a preferred technical solution of the present invention, it also includes a support plate, which is fixed on the base and arranged on the side of the second clamping plate away from the first clamping plate; the driving device is fixed on the support plate, and the output end of the driving device is fixedly connected to the second clamping plate.

[0010] The support plate design strengthens the connection between the base and the second pressure plate, increasing the rigidity and stability of the entire device and reducing potential deformation or displacement during the compression process. The output of the drive unit is directly connected to the second pressure plate, enabling more efficient power transmission, reducing energy loss, and improving drive efficiency.

[0011] In a preferred technical solution of the present invention, a guide channel is provided on the support plate, a guide rod is provided in the guide channel, the guide rod has a first end and a second end which are arranged opposite to each other, the first end passes through the guide channel and is fixedly connected to the second clamping plate, and the second end is exposed on one side of the support plate.

[0012] The design of the guide channel and guide rod ensures linearity and stability during the movement of the second pressure plate, improving its motion precision. The guide rod reduces friction and wear during movement, extending the device's service life and reducing maintenance costs. Furthermore, the guidance of the guide rod simplifies the design of the drive mechanism, reducing the need for complex transmission mechanisms.

[0013] In a preferred technical solution of the present invention, a locking ring is provided on the second end, the locking ring protrudes outward from the outer wall of the second end, and the outer diameter of the locking ring is larger than the inner diameter of the guide channel.

[0014] The locking ring is used to prevent the guide rod from accidentally sliding out of the guide channel during the pressing process, reducing the risk of equipment failure and operational accidents and improving operational safety.

[0015] In a preferred technical solution of the present invention, a locking piece is further provided on the support plate, and one end of the locking piece passes through the support plate and is fixedly connected to the second pressing plate.

[0016] The locking member is used to lock the second pressing plate after it moves to the target position, so that the position of the second pressing plate remains stable, thereby avoiding the movement of the second pressing plate due to the extrusion of the foaming material during the foaming process, resulting in the foaming effect not meeting the expected situation.

[0017] In a preferred technical solution of the present utility model, a mounting bracket is provided on the base, a connecting seat is provided on the mounting bracket, the connecting seat is pivotally connected to the mounting bracket, and the first pressing plate is fixed on the connecting seat;

[0018] A limiting block is provided on the mounting frame, and the first pressing plate can be rotated on the mounting frame through the connecting seat; when the first pressing plate abuts against the limiting block, the plane where the first pressing plate is located is perpendicular to the plane where the top of the base is located.

[0019] Because the first pressing plate can rotate on the mounting frame, its position can be adjusted when placing the product to be foamed, allowing the product to be placed more smoothly into the pressing station, which helps improve production efficiency. The provision of the limit block ensures that the surface of the first pressing plate and the surface of the product to be foamed are in close contact during pressing, which helps to ensure the foaming quality of the product.

[0020] In a preferred technical solution of the present invention, a receiving groove is provided on one side of the first pressing plate and / or the second pressing plate, a detachable clamping plate is provided in the receiving groove, and the clamping plate avoids setting multiple hole-blocking protrusions.

[0021] The surface of the clipping plate is designed with multiple hole-blocking protrusions, so that the clipping plate can be quickly replaced according to the specific needs of the product to be foamed to adapt to products of different shapes and sizes, which improves the adaptability and flexibility of the device.

[0022] The removable design of the clip plate allows for quick replacement if it is damaged or needs to be replaced to accommodate new products, reducing maintenance time and costs. The precise plugging protrusion design reduces the waste of foam material during the compaction process and improves material utilization efficiency.

[0023] In a preferred technical solution of the present invention, a coating is provided on the wall surface of the clamping plate, and the coating includes a bottom layer and a surface layer. The bottom layer is coated on the wall surface of the clamping plate, and the surface layer is coated on the bottom layer. The surface layer is made of non-stick material.

[0024] The surface layer is made of a non-stick material, such as Teflon or other similar heat- and chemical-resistant non-stick materials. This design reduces adhesion when the clip plate contacts the foam material, making the compression and release process smoother and facilitating cleaning and maintenance. The protective coating reduces the frequency of clip plate replacement, reducing maintenance costs and material consumption.

[0025] In a preferred technical solution of the present invention, a receiving groove is provided on one side of the first pressing plate and / or the second pressing plate, an expansion member is provided in the receiving groove, and the expansion member is fixed to the first pressing plate and / or the second pressing plate;

[0026] The expansion member includes an air bag, and the air bag is externally connected to an air supply device.

[0027] The design of the airbag and air supply device allows for flexible adjustment of the compression force by adjusting the airbag pressure to meet the foaming and compression requirements of different products. Adjusting the airbag pressure allows for precise control of the compression force, allowing the device to adapt to foaming products of varying shapes and sizes, enhancing its flexibility and adaptability. Furthermore, the uniform pressure provided by the airbag helps ensure even distribution of the foaming material during the compression process, improving foaming quality. Furthermore, by quickly adjusting the airbag pressure, the compression force can be adjusted quickly, reducing equipment set-up time and improving production efficiency.

[0028] The third object of the present utility model is to provide an electrical appliance box, comprising a bottom plate, a side plate provided on the bottom plate, the side plate being annularly provided on the bottom plate, a foaming cavity provided in the side plate, and the foaming cavity being filled with a foaming material;

[0029] The foaming material is filled by using the foaming and pressing device as described above.

[0030] This electrical box utilizes the aforementioned foaming and clamping device during the foaming process. Using two foaming and clamping devices, precisely controlling the force and distance of the clamping force ensures uniform filling of the foaming cavity, thereby improving the overall performance of the box. This uniform filling of the foaming cavity provides enhanced shock absorption, protecting internal components from shock and vibration, and making the box more durable and reliable.

[0031] The beneficial effects of the utility model are:

[0032] The present invention provides a foaming and pressing device comprising a base and a driving device. A first pressing plate and a second pressing plate are mounted on the base. The first pressing plate is mounted on the base, and the second pressing plate is movably mounted to one side of the first pressing plate. A pressing station for the product to be foamed is formed between the second and first pressing plates. A driving device is fixed to the base and drives the second pressing plate to move toward or away from the first pressing plate. The device can be used during the foaming process of an electrical appliance box. In practical applications, the box is placed in the pressing station between the first and second pressing plates. Subsequently, the driving device is activated, and the second pressing plate begins to move toward the first pressing plate until the two pressing plates are in close contact with the product to be foamed, achieving compression. The compression force can be precisely controlled by adjusting the stroke or pressure of the driving device to meet the foaming requirements of different products. After the foaming process is completed, the driving device is activated again, moving the second pressing plate away from the first pressing plate, thereby releasing the compressed product. This allows the foaming and pressing device to be ready for the next product to be foamed. This device eliminates the tedious step of manually wrapping masking tape through an automated pressing process, significantly improving foaming efficiency and reducing production cycle time. Furthermore, by precisely controlling the pressing force and duration through a drive mechanism, the device ensures uniform and appropriate pressure on the foamed product during the foaming process, thereby guaranteeing foaming quality. The automated pressing process reduces physical labor and intensity, thereby helping to lower production costs.

[0033] The present application also provides an electrical box for a foaming and pressing device implemented based on the above-mentioned foaming and pressing device. The electrical box uses the above-mentioned foaming and pressing device to fill the foaming material, which can improve the efficiency of the foaming operation, reduce dependence on manual operation, reduce labor costs, and also help improve the foaming quality.

[0048] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0049] In the field of modern electrical appliance manufacturing, the installation and fixation of electrical box components are key links to ensure the performance and stability of the entire electrical appliance. Electrical box components are usually installed inside the entire machine. In order to prevent vibration during use of the electrical box and reduce the noise generated by internal wiring components, the side walls of an existing electrical box are made into a cavity structure. Multiple small holes are opened on the side walls of this electrical box and foam filling is performed to enhance the structural stability and sound insulation effect of the electrical box. However, there are some limitations in the foam filling process of this electrical box: due to the large number of small holes on the electrical box, the foam material needs to be compressed to prevent overflow, but the electrical box usually has only one-sided opening, which makes the compression operation difficult. The traditional solution is to use a large amount of masking paper to wrap and wrap the electrical box to achieve the compression effect. Although this method can solve the problem to a certain extent, it has obvious disadvantages: first, it is time-consuming, affecting production efficiency; second, it is labor-intensive and requires high physical strength from the operators; finally, since a large amount of masking tape is required, the cost is high, which is not conducive to cost control and environmental protection; and the viscosity and fit of masking tape are limited, making it difficult to ensure that all small holes can be tightly compressed, which may cause the foam material to overflow during the filling process, affecting the quality and performance of the product.

[0050] Based on this, the present application provides a foaming and pressing device.

[0051] Example 1

[0052] like Figures 1-11 As shown, a foaming and pressing device provided in this embodiment includes a base 2; a first pressing plate 1 and a second pressing plate 3 are provided on the base 2, wherein the first pressing plate 1 is provided on the base 2, and the second pressing plate 3 is movably provided on one side of the first pressing plate 1, and a pressing station 11 for placing the product to be foamed is formed between the second pressing plate 3 and the first pressing plate 1;

[0053] A driving device 7 is fixed on the base 2 , and the driving device 7 drives the second pressing plate 3 to move so that the second pressing plate 3 approaches or moves away from the first pressing plate 1 .

[0054] In one embodiment, the driving device 7 can be a manual push rod. In this embodiment, the production staff manually pushes the push rod to drive the movement of the second pressing plate 3, so that the second pressing plate 3 can be close to or away from the first pressing plate 1.

[0055] In another embodiment, the drive device 7 can be an electric, pneumatic or hydraulic drive device 7, such as a cylinder or a push rod motor. In actual production, the most suitable power source can be selected as needed. The drive device 7 can also be connected to the second pressing plate 3 through a connecting rod mechanism to ensure that the second pressing plate 3 can accurately approach or move away from the first pressing plate 1. During the foaming and pressing process, the product to be foamed is first placed on the pressing station 11 between the first pressing plate 1 and the second pressing plate 3. Subsequently, the drive device 7 is started, and the second pressing plate 3 begins to move toward the first pressing plate 1 until the two pressing plates are in close contact with the product to be foamed to achieve compression. The compression force can be precisely controlled by adjusting the stroke or pressure of the drive device 7 to meet the foaming requirements of different products. After the foaming process is completed, the drive device 7 is started again to move the second pressing plate 3 away from the first pressing plate 1, thereby releasing the compressed product. In this way, the foaming and pressing device can be ready for the next product to be foamed.

[0056] This foaming and pressing device eliminates the tedious step of manually wrapping masking tape through an automated pressing process, significantly improving foaming efficiency and reducing production cycle time. Furthermore, the operation of the drive device 7 allows for precise control of the pressing force and duration, ensuring that the foamed product is subjected to uniform and appropriate pressure during the foaming process, thereby guaranteeing foaming quality. This device also reduces the use of masking tape and manual operation, helping to reduce production costs while improving material utilization.

[0057] More specifically, the device also includes a support plate 4, which is fixed on the base 2, and the support plate 4 is arranged on the side of the second clamping plate 3 away from the first clamping plate 1; the driving device 7 is fixed on the support plate 4, and the output end of the driving device 7 is fixedly connected to the second clamping plate 3.

[0058] Support plate 4 provides a mounting location for drive unit 7. Its design strengthens the connection between base 2 and second compression plate 3, enhancing the rigidity and stability of the entire assembly and reducing potential deformation or displacement during the compression process. The output of drive unit 7 is directly connected to second compression plate 3, enabling more efficient power transmission, reducing energy loss, and improving drive efficiency.

[0059] In one embodiment, the foaming and pressing device of the present application can be used during the foaming material filling process of an electrical box. Specifically, one of the side walls of the electrical box can be placed in a pressing station 11. After the first pressing plate 1 and the second pressing plate 3 jointly press the side wall of the electrical box, the foaming material can be filled into the side wall of the electrical box, so that the foaming material fills the cavity of the side wall of the electrical box.

[0060] Example 2

[0061] This embodiment is improved on the basis of embodiment 1.

[0062] like Figures 1-11 As shown, in this embodiment, a guide channel 41 is provided on the support plate 4, and a guide rod 5 is provided in the guide channel 41. The guide rod 5 has a first end and a second end that are relatively arranged. The first end passes through the guide channel 41 and is fixedly connected to the second clamping plate 3, and the second end is exposed on one side of the support plate 4. This connection method ensures that the second clamping plate 3 can move smoothly along the guide channel 41 to achieve precise clamping operation.

[0063] During the foaming process, the product to be foamed is first placed between the two compression plates. Subsequently, driven by the drive device 7, the second compression plate 3 moves along the guide rod 5 until it contacts the first compression plate 1 and compresses the sidewall of the product to be foamed. After adjusting the compression force, the foaming material is filled into the product and the foaming process is carried out. The design of the guide rod 5 reduces friction and wear on the second compression plate 3 during movement, extending the service life of the device and reducing maintenance costs. Furthermore, the guidance of the guide rod 5 simplifies the design of the drive device 7, reducing the need for complex transmission mechanisms.

[0064] In a better implementation of this embodiment, two guide channels 41 of the present application can be provided, and a guide rod 5 is provided in each guide channel 41 .

[0065] Example 3

[0066] This embodiment is improved on the basis of embodiment 2.

[0067] like Figures 1-11 As shown, in this embodiment, a locking ring 51 is provided on the second end. The locking ring 51 protrudes outward from the outer wall of the second end, and the outer diameter of the locking ring 51 is greater than the inner diameter of the guide channel 41.

[0068] The locking ring 51 protrudes outward from the outer wall of the second end of the guide rod 5, and its outer diameter is larger than the inner diameter of the guide channel 41. This design ensures that the locking ring 51 can connect with the side wall of the guide channel 41 when the guide rod 5 moves to the extreme position, thereby limiting the guide rod 5 and preventing the guide rod 5 from accidentally sliding out of the guide channel 41.

[0069] This can reduce the risk of equipment failure and operational accidents, and improve operational safety.

[0070] Example 4

[0071] This embodiment is improved on the basis of embodiment 2.

[0072] like Figures 1-11 As shown, in this embodiment, a locking member 42 is further provided on the support plate 4 , and one end of the locking member 42 passes through the support plate 4 and is fixedly connected to the second pressing plate 3 .

[0073] After the second pressing plate 3 moves to the target position, the locking member 42 is used to fix the second pressing plate 3 in place. In this way, even if the foaming material is squeezed due to expansion during the foaming process, the position of the second pressing plate 3 can be kept stable, thus avoiding the problem of poor foaming effect caused by the movement of the pressing plate.

[0074] In this embodiment, the locking member 42 locks the second pressing plate 3, maintaining a stable position. This prevents movement of the second pressing plate 3 due to the extrusion of the foaming material during the foaming process, ensuring the stability of the second pressing plate 3 during the foaming process and preventing uneven distribution of the foaming material due to movement of the pressing plate, thereby improving foaming quality. This reduces rework caused by movement of the pressing plate and improves production efficiency.

[0075] Specifically, the locking member 42 may be a locking screw.

[0076] Example 5

[0077] This embodiment is improved on the basis of embodiment 1.

[0078] like Figures 1-11 As shown, in this embodiment, a mounting bracket 9 is provided on the base 2, a connecting seat is provided on the mounting bracket 9, the connecting seat is pivotally connected to the mounting bracket 9, and the first pressing plate 1 is fixed on the connecting seat;

[0079] The mounting frame 9 is provided with a limit block 91, and the first pressing plate 1 can rotate on the mounting frame 9 via the connecting seat. When the first pressing plate 1 abuts the limit block 91, the plane of the first pressing plate 1 is perpendicular to the plane of the top of the base 2. Specifically, a side wall where the limit block 91 meets the first pressing plate 1 can be provided with rubber to provide a buffer between the limit block 91 and the first pressing plate 1.

[0080] Because the first pressing plate 1 can rotate on the mounting frame 9, the position of the first pressing plate 1 can be adjusted when placing the product to be foamed, so that the product to be foamed can be placed more smoothly into the pressing station 11, which helps improve production efficiency. The provision of the limit block 91 ensures that the surface of the first pressing plate 1 and the surface of the product to be foamed are in contact with each other during pressing, which helps to ensure the foaming quality of the product.

[0081] Example 6

[0082] This embodiment is improved on the basis of embodiment 1.

[0083] like Figures 1-11 As shown, in this embodiment, a receiving groove is provided on one side of the first pressing plate 1 and / or the second pressing plate 3, and a detachable clamping plate 6 is provided in the receiving groove, and the clamping plate 6 is provided with multiple hole-blocking protrusions 61.

[0084] The surface of the clamping plate 6 is designed with multiple hole-blocking protrusions 61, so that the clamping plate 6 can be quickly replaced according to the specific needs of the product to be foamed to adapt to products of different shapes and sizes, which improves the adaptability and flexibility of the device.

[0085] Furthermore, the detachable design of the clip plate 6 allows for quick replacement when it is damaged or needs to be replaced to accommodate new products, reducing maintenance time and costs. The precise design of the hole-blocking protrusion 61 reduces the waste of foaming material during the compaction process and improves the efficiency of material use.

[0086] Example 7

[0087] This embodiment is improved on the basis of embodiment 6.

[0088] like Figures 1-11 As shown, in this embodiment, a coating 12 is provided on the wall surface of the clamping plate 6, and the coating 12 includes a bottom layer 121 and a surface layer 122. The bottom layer 121 is coated on the wall surface of the clamping plate 6, and the surface layer 122 is coated on the bottom layer 121. The surface layer 122 is made of non-stick material.

[0089] In one embodiment, the surface layer 122 is made of a non-stick material, such as Teflon or other similar non-stick materials that are heat-resistant and chemically resistant. It should be emphasized that the non-stick surface layer 122 effectively improves the release of the clipping plate 6 after foaming. This design reduces adhesion when the clipping plate 6 contacts the foaming material, facilitating smoother compression and release processes and facilitating cleaning and maintenance. The protective effect of the coating 12 reduces the frequency of replacement of the clipping plate 6, thereby reducing maintenance costs and material consumption.

[0090] In another embodiment, the bottom layer 121 is coated with a solvent-based primer, and the surface layer 122 is formed by coating 856G-304 industrial coating on the bottom layer 121. The bottom layer 121 can increase the adhesion between the surface layer 122 and the clip plate 6, thereby improving the durability of the surface layer 122.

[0091] Example 8

[0092] This embodiment is improved on the basis of embodiment 1.

[0093] In this embodiment, a receiving groove is provided on one side of the first pressing plate 1 and / or the second pressing plate 3, an expansion member is provided in the receiving groove, and the expansion member is fixed on the first pressing plate 1 and / or the second pressing plate 3;

[0094] The expansion member includes an air bag 8, and the air bag 8 is externally connected to an air supply device.

[0095] The design of the airbag 8 and the air supply device allows for flexible adjustment of the compression force by regulating the air pressure of the airbag 8 to accommodate the foaming and compression requirements of different products. Adjusting the air pressure of the airbag 8 allows for precise control of the compression force, allowing the device to adapt to foamed products of varying shapes and sizes, thereby enhancing the device's flexibility and adaptability. Furthermore, the uniform pressure provided by the airbag 8 helps ensure even distribution of the foaming material during the compression process, improving foaming quality. Furthermore, by rapidly adjusting the air pressure of the airbag 8, the compression force can be quickly adjusted, reducing equipment adjustment time and improving production efficiency.

[0096] Example 9

[0097] This embodiment is improved on the basis of embodiment 1.

[0098] like Figures 1-12 As shown, this embodiment provides a method for using a foaming and pressing device, which is implemented based on the foaming and pressing device described above;

[0099] The method of use comprises the following steps:

[0100] S1. Obtain two foaming and pressing devices, wherein the two foaming and pressing devices are arranged opposite to each other;

[0101] S2. Adjust the relative distance between the two foaming and pressing devices so that the distance between the two pressing stations 11 on the two foaming and pressing devices reaches the target value; this process adjusts the relative distance between the two foaming and pressing devices according to the size of the product to be foamed, ensuring that the distance between the pressing stations 11 is suitable for the embedding of the product side wall to achieve the target value.

[0102] S3, fasten the product to be foamed on the two foaming and pressing devices so that the side walls of the product to be foamed are respectively embedded in the two pressing stations 11;

[0103] S4. Adjust the distance between the first pressing plate 1 and the second pressing plate 3 so that the first pressing plate 1 and the second pressing plate 3 press the side wall of the product to be foamed;

[0104] S5. Fill the product to be foamed with foaming material and perform the foaming operation.

[0105] The method of using the foaming and pressing device can be used to fill foaming material into an electrical box. The two pressing stations 11 on the two foaming and pressing devices can respectively support the opposite side walls of the electrical box, thereby pressing the opposite side walls of the electrical box to fill the foaming material into the cavity of the electrical box.

[0106] In actual applications, two foaming and clamping devices can be set on the base, and the base is provided with a slide rail. The bases 2 of the two foaming and clamping devices are both set on the slide rail, so that the base 2 can be adjusted on the base, that is, the distance between the two foaming devices is changed to adapt to the foaming production requirements of electrical boxes of different sizes.

[0107] This method ensures uniform filling of the foaming material by precisely controlling the distance and pressing force of the pressing station 11, improving the product's sealing and structural integrity. Precise pressing control reduces foaming material waste, improves material utilization efficiency, and reduces production costs. Furthermore, this method can be widely applied to foaming operations for a variety of products, increasing equipment utilization and flexibility.

[0110] like Figures 1-11 As shown, this embodiment provides an electrical box 100, including a bottom plate, a side plate provided on the bottom plate, the side plate being annularly provided on the bottom plate, a foaming cavity 110 provided in the side plate, and the foaming cavity 110 being filled with a foaming material;

[0111] The filling process of the foaming material is achieved by using the foaming and pressing device as described above.

[0112] The electrical box 100 utilizes the aforementioned foaming and pressing device during the foaming process. Using two foaming and pressing devices, precisely controlling the pressing force and distance ensures uniform filling of the foaming material into the foaming cavity 110, thereby improving the overall performance of the electrical box 100. This uniform filling of the foaming material within the foaming cavity 110 of the electrical box 100 provides enhanced shock absorption, protecting internal components from shock and vibration, and making the electrical box 100 more durable and reliable.

[0113] The present application provides a process of filling the foaming material into the foaming cavity 110 of the electrical box 100, which is as follows:

[0114] Two foaming and pressing devices are selected, and the distance between the foaming and pressing devices is adjusted according to the position of the foaming cavity 110 of the electrical box 100 so that the pressing station 11 can accommodate the two opposite foaming cavities 110 of the electrical box 100 .

[0115] The electrical box 100 is placed in the pressing station 11 , and the position of the second pressing plate 3 is adjusted so that the second pressing plate 3 can move and press the electrical box 100 between the first pressing plate 1 and the second pressing plate 3 .

[0116] After the electrical box 100 is compressed, the foaming material can be filled into the foaming cavity 110. In a more preferred embodiment, a pressure sensor can be set on the wall of the first compression plate 1 to measure the pressure exerted on the first compression plate 1 to determine whether the electrical box 100 is compressed.

[0117] After the foaming material is filled into the foaming cavity 110 and the foaming time reaches a preset time, the second pressing plate 3 is moved and the electrical box 100 can be removed to complete the filling of the foaming material in the electrical box 100.

[0118] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0119] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
