Description

Technical Field

[0001] The present invention relates to the field of foaming technology, and in particular to a foaming pressing device, a method for using the foaming pressing device and an electrical 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 wall of an existing electrical box is made into a cavity structure. A plurality of small holes are opened on the side wall 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 foaming filling process of the electrical box: due to the large number of small holes on the electrical box, the foaming material needs to be pressed to prevent overflow, but the electrical box usually has only one-sided opening, which makes the pressing operation difficult. The traditional solution is to wrap and wrap the electrical box with a large amount of masking paper to achieve the pressing 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, and it is difficult to ensure that all small holes can be tightly pressed, which may cause the foaming 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. Summary of the invention

[0004] In order to overcome the problems existing in the related art, one of the objects 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, comprising a base; a first pressing plate and a second pressing plate are arranged on the base, the first pressing plate is arranged on the base, the second pressing plate is movably arranged 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 driving device can be an electric, pneumatic or hydraulic driving device, and the most suitable power source can be selected according to the needs. The driving device can be connected to the second clamping plate through a connecting rod mechanism to ensure that the second clamping plate can accurately approach or move away from the first clamping plate. During the foaming and pressing process, the product to be foamed is first placed on the clamping station between the first clamping plate and the second clamping plate. Subsequently, the driving device is started, and the second clamping plate begins to move toward the first clamping plate until the two clamping plates are in close contact with the product to be foamed to achieve compression. The clamping 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 started again to move the second clamping plate away from the first clamping 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] The foaming and pressing device eliminates the tedious steps of manually wrapping masking tape through an automated pressing process, significantly improves the foaming efficiency, and reduces the production cycle. In addition, through the operation of the driving device, the pressing force and pressing time can also be accurately controlled, so as to ensure that the product to be foamed is subjected to uniform and appropriate pressure during the foaming process, thereby ensuring the foaming quality. The device also reduces the use of masking tape and manual operation, which helps to reduce production costs and improve the utilization rate of materials.

[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 a 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 design of the support plate strengthens the connection between the base and the second clamping plate, improves the rigidity and stability of the entire device, and reduces the deformation or displacement that may occur during the clamping process. The output end of the drive device is directly connected to the second clamping plate. This design can transmit power more effectively, reduce energy loss, and improve driving 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 the guide rod ensures the linearity and stability of the second clamping plate during movement, and improves the accuracy of the second clamping plate's movement. The design of the guide rod reduces the friction and wear of the second clamping plate during movement, prolongs the service life of the device, and reduces maintenance costs. Moreover, due to the guidance of the guide rod, the entire device can simplify the design of the drive device and reduce 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 greater 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 clamping process, reducing the risk of equipment failure and operating accidents and improving the safety of operation.

[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 piece is used to lock the second clamping plate after it moves to the target position, so that the position of the second clamping plate remains stable, thereby avoiding the movement of the second clamping plate due to the extrusion of the foaming material during the foaming process, resulting in the foaming effect not meeting the expected level.

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

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

[0019] Since the first pressing plate can rotate on the mounting frame, the position of the first pressing plate can be adjusted when placing the product to be foamed, so that the product to be foamed can be placed in the pressing station more smoothly, which helps to improve production efficiency. The setting of the limit block ensures that the surface of the first pressing plate 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.

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

[0021] The surface of the clamping plate is designed with multiple hole-blocking protrusions, so that the clamping 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] Moreover, the detachable design of the card plate allows for quick replacement when the card plate is damaged or needs to be replaced to adapt to new products, reducing maintenance time and costs. The precise plugging protrusion design reduces the waste of foaming materials during the compaction process and improves the efficiency of material use.

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

[0024] The surface layer is made of non-stick material, such as Teflon or other similar non-stick materials that are resistant to high temperatures and chemical corrosion. This design reduces adhesion when the card plate contacts the foam material, making the compression and release process smoother and easier to clean and maintain. Due to the protective effect of the coating, the replacement frequency of the card plate is reduced, thereby 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 on 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 the air supply device allows the compression force to be flexibly adjusted by adjusting the air pressure of the airbag to meet the foaming and compression requirements of different products. By adjusting the air pressure of the airbag, the compression force can be accurately controlled, so that the device can adapt to products to be foamed of different shapes and sizes, improving the flexibility and adaptability of the device. Moreover, the uniform pressure provided by the airbag helps to ensure that the foaming material is evenly distributed during the compression process, improving the foaming quality. In addition, by quickly adjusting the air pressure of the airbag, the compression force can be quickly adjusted, reducing the equipment adjustment time and improving production efficiency.

[0028] The second object of the present invention is to provide a method for using a foaming and pressing device, which is implemented based on the foaming and pressing device as described above;

[0029] The method of use comprises the following steps:

[0030] Obtain two foaming and pressing devices, wherein the two foaming and pressing devices are arranged opposite to each other;

[0031] Adjust the relative distance between the two foaming and pressing devices so that the distance between the two pressing stations 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 is suitable for the embedding of the product side wall to achieve the target value.

[0032] The product to be foamed is buckled into two foaming and pressing devices, so that the side walls of the product to be foamed are respectively embedded in the two pressing stations;

[0033] Adjusting the distance between the first pressing plate and the second pressing plate so that the first pressing plate and the second pressing plate press the side wall of the product to be foamed;

[0034] Fill the product to be foamed with foaming material and perform the foaming operation.

[0035] This method can ensure uniform filling of foaming materials and improve the sealing and structural integrity of products by accurately controlling the distance and pressing force of the pressing stations. Accurate pressing control reduces the waste of foaming materials, improves the efficiency of material use, and reduces production costs. In addition, this method can be widely used in the foaming operations of various products, improving the utilization rate and flexibility of equipment.

[0036] The third object of the present invention is to provide an electrical box, comprising a bottom plate, a side plate arranged on the bottom plate, the side plate being arranged on the bottom plate in an annular shape, a foaming cavity being arranged in the side plate, and the foaming cavity being filled with a foaming material;

[0037] The filling process of the foaming material is realized by using the foaming and pressing device as described above.

[0038] The electrical box adopts the method of using the foaming pressing device as described above during the filling process of the foaming material of the electrical box. That is, two foaming pressing devices are used to ensure that the foaming material is evenly filled into the foaming cavity by accurately controlling the pressing force and distance, thereby improving the overall performance of the electrical box. The even filling of the foaming material in the foaming cavity of the electrical box provides a better shock absorption effect, protects the internal components from impact and vibration, and makes the electrical box more durable and reliable.

[0039] The beneficial effects of the present invention are:

[0040] The present invention provides a foaming and pressing device, which includes a base and a driving device. The base is provided with a first pressing plate and a second pressing plate. The first pressing plate is arranged on the base, and the second pressing plate is movably arranged on one side of the first pressing plate. A pressing station for placing a product to be foamed is formed between the second pressing plate and the first pressing plate. The driving device is fixed on the base, and the driving device drives the second pressing plate to move so that the second pressing plate is close to or away from the first pressing plate. The device can be used in the foaming process of an electrical box. In actual applications, the electrical box is placed on the pressing station between the first pressing plate and the second pressing plate. Subsequently, the driving 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 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 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 prepared for the next product to be foamed. The device eliminates the tedious steps of manually wrapping masking paper through the automated pressing process, significantly improves foaming efficiency and reduces production cycles. Moreover, by accurately controlling the pressing force and pressing time through the drive device, the device can ensure that the product to be foamed is subjected to uniform and appropriate pressure during the foaming process, thereby ensuring the foaming quality. The automated pressing process reduces the physical labor of workers, reduces labor intensity, and also helps to reduce production costs.

[0041] The present application also provides a method for using the foaming and pressing device based on the foaming and pressing device and an electrical box, and the electrical box is filled with foaming material using the method for using the foaming and pressing device. The method is applicable to products that need to be filled with foaming materials, and by pressing the product to be foamed with two pressing plates, the efficiency of the foaming operation can be improved, the dependence on manual operation is reduced, the labor cost is reduced, and the foaming quality is also improved.

[0056] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the 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. On the contrary, 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.

[0057] 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 wall of an existing electrical box is made into a cavity structure. A plurality of small holes are opened on the side wall 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 foaming filling process of the electrical box: due to the large number of small holes on the electrical box, the foaming material needs to be pressed to prevent overflow, but the electrical box usually has only one-sided opening, which makes the pressing operation difficult. The traditional solution is to wrap and wrap the electrical box with a large amount of masking paper to achieve the pressing 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, and it is difficult to ensure that all small holes can be tightly pressed, which may cause the foaming material to overflow during the filling process, affecting the quality and performance of the product.

[0058] Based on this, the present application provides a foaming and pressing device.

[0059] Example 1

[0060] like Figure 1-Figure 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 arranged on the base 2, the first pressing plate 1 is arranged on the base 2, the second pressing plate 3 is movably arranged on one side of the first pressing plate 1, and a pressing station 11 for placing a product to be foamed is formed between the second pressing plate 3 and the first pressing plate 1;

[0061] 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 .

[0062] In one embodiment, the driving device 7 may 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.

[0063] In another embodiment, the driving device 7 can be an electric, pneumatic or hydraulic driving 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 driving device 7 can also be connected to the second clamping plate 3 through a connecting rod mechanism to ensure that the second clamping plate 3 can accurately approach or move away from the first clamping plate 1. During the foaming and pressing process, the product to be foamed is first placed on the clamping station 11 between the first clamping plate 1 and the second clamping plate 3. Subsequently, the driving device 7 is started, and the second clamping plate 3 begins to move toward the first clamping plate 1 until the two clamping plates are in close contact with the product to be foamed to achieve compression. The clamping force can be precisely controlled by adjusting the stroke or pressure of the driving device 7 to meet the foaming requirements of different products. After the foaming process is completed, the driving device 7 is started again to move the second clamping plate 3 away from the first clamping 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.

[0064] The foaming and pressing device eliminates the cumbersome steps of manually wrapping masking tape through an automated pressing process, significantly improves the foaming efficiency, and reduces the production cycle. In addition, through the operation of the driving device 7, the pressing force and pressing time can also be accurately controlled, so as to ensure that the product to be foamed is subjected to uniform and appropriate pressure during the foaming process, thereby ensuring the foaming quality. The device also reduces the use of masking tape and manual operation, and the device helps to reduce production costs while improving the utilization rate of materials.

[0065] 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.

[0066] The support plate 4 provides a mounting position for the drive device 7. The design of the support plate 4 strengthens the connection between the base 2 and the second clamping plate 3, improves the rigidity and stability of the entire device, and reduces the deformation or displacement that may occur during the clamping process. The output end of the drive device 7 is directly connected to the second clamping plate 3. Such a design can more effectively transmit power, reduce energy loss, and improve driving efficiency.

[0067] In one embodiment, the foaming and pressing device of the present application can be used in the foaming material filling process of the electrical box. Specifically, one of the side walls of the electrical box can be placed in the pressing station 11, and 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.

[0068] Example 2

[0069] This embodiment is improved on the basis of embodiment 1.

[0070] like Figure 1-Figure 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 which 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.

[0071] During the foaming material filling process, the product to be foamed is first placed between the two pressing plates. Subsequently, through the action of the driving device 7, the second pressing plate 3 moves along the guide rod 5 until it contacts the first pressing plate 1 and presses the side wall of the product to be foamed. After adjusting the pressing force, the foaming material is filled into the product and the foaming operation is performed. The design of the guide rod 5 reduces the friction and wear of the second pressing plate 3 during the movement, prolongs the service life of the device, and reduces the maintenance cost. Moreover, due to the guidance of the guide rod 5, the entire device can simplify the design of the driving device 7 and reduce the need for complex transmission mechanisms.

[0072] In a better implementation of this embodiment, two guide channels 41 of the present application may be provided, and a guide rod 5 is provided in each guide channel 41 .

[0073] Example 3

[0074] This embodiment is improved on the basis of Embodiment 2.

[0075] like Figure 1-Figure 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.

[0076] 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 slipping out of the guide channel 41.

[0077] This can reduce the risk of equipment failure and operating accidents, and improve operational safety.

[0078] Example 4

[0079] This embodiment is improved on the basis of Embodiment 2.

[0080] like Figure 1-Figure 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 .

[0081] After the second pressing plate 3 moves to the target position, the second pressing plate 3 is fixed in place using the locking member 42. 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 remain stable, thereby avoiding the problem of poor foaming effect caused by the movement of the pressing plate.

[0082] In this embodiment, the second pressing plate 3 is locked by the locking member 42, so that the position of the second pressing plate 3 is stable and unchanged, thereby preventing the second pressing plate 3 from moving 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, preventing the uneven distribution of the foaming material due to the movement of the pressing plate, and improving the foaming quality. This can reduce rework caused by the movement of the pressing plate and improve production efficiency.

[0083] Specifically, the locking member 42 may be a locking screw.

[0084] Example 5

[0085] This embodiment is improved on the basis of embodiment 1.

[0086] like Figure 1-Figure 11 As shown, in this embodiment, a mounting frame 9 is provided on the base 2, a connecting seat is provided on the mounting frame 9, the connecting seat is pivotally connected to the mounting frame 9, and the first pressing plate 1 is fixed on the connecting seat;

[0087] The mounting frame 9 is provided with a limit block 91, and the first pressing plate 1 can rotate on the mounting frame 9 through the connecting seat; when the first pressing plate 1 abuts against the limit block 91, the plane where the first pressing plate 1 is located is perpendicular to the plane where the top of the base 2 is located. Specifically, a side wall where the limit block 91 and the first pressing plate 1 meet can be provided with rubber to achieve a buffer between the limit block 91 and the first pressing plate 1.

[0088] Since 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 in the pressing station 11, which helps to improve production efficiency. The setting 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.

[0089] Example 6

[0090] This embodiment is improved on the basis of embodiment 1.

[0091] like Figure 1-Figure 11 As shown, in this embodiment, a receiving groove is provided on one side of the first clamping plate 1 and / or the second clamping plate 3, and a detachable clamping plate 6 is provided in the receiving groove. The clamping plate 6 is provided with a plurality of hole blocking protrusions 61.

[0092] 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.

[0093] Moreover, the detachable design of the clamping plate 6 allows for quick replacement when the clamping plate 6 is damaged or needs to be replaced to adapt to new products, thereby reducing maintenance time and cost. The precise design of the hole-blocking protrusion 61 reduces the waste of foaming material during the compaction process and improves the use efficiency of the material.

[0094] Example 7

[0095] This embodiment is improved on the basis of Embodiment 6.

[0096] like Figure 1-Figure 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, and the surface layer 122 is made of non-stick material.

[0097] 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 resistant to high temperatures and chemical corrosion. It should be emphasized that the surface layer 122 is made of a non-stick material, which can effectively improve the demoulding effect of the clamping plate 6 after foaming. Such a design can reduce adhesion when the clamping plate 6 contacts the foaming material, making the pressing and releasing process smoother and easier to clean and maintain. Due to the protective effect of the coating 12, the replacement frequency of the clamping plate 6 is reduced, thereby reducing maintenance costs and material consumption.

[0098] 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.

[0099] Example 8

[0100] This embodiment is improved on the basis of embodiment 1.

[0101] 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 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;

[0102] The expansion member includes an air bag 8, and the air bag 8 is externally connected to an air supply device.

[0103] The design of the airbag 8 and the air supply device allows the compression force to be flexibly adjusted by adjusting the air pressure of the airbag 8 to adapt to the foaming compression requirements of different products. By adjusting the air pressure of the airbag 8, the compression force can be accurately controlled, so that the device can adapt to products to be foamed of different shapes and sizes, thereby improving the flexibility and adaptability of the device. Moreover, the uniform pressure provided by the airbag 8 helps to ensure that the foaming material is evenly distributed during the compression process, thereby improving the foaming quality. In addition, by quickly adjusting the air pressure of the airbag 8, the compression force can be quickly adjusted, thereby reducing the equipment adjustment time and improving production efficiency.

[0104] Example 9

[0105] This embodiment is improved on the basis of embodiment 1.

[0106] like Figure 1-Figure 12 As shown, this embodiment provides a method for using a foaming and pressing device, and the method is implemented based on the foaming and pressing device as described above;

[0107] The method of use comprises the following steps:

[0108] S1, obtaining two foaming and pressing devices, wherein the two foaming and pressing devices are arranged opposite to each other;

[0109] 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.

[0110] S3, buckling 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;

[0111] S4, adjusting 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;

[0112] S5. Fill the product to be foamed with foaming material and perform the foaming operation.

[0113] 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.

[0114] In actual applications, two foaming and clamping devices can be arranged on a base, and a slide rail is arranged on the base. The bases 2 of the two foaming and clamping devices are arranged 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, so as to adapt to the foaming production requirements of electrical boxes of different sizes.

[0115] The method can ensure uniform filling of the foaming material and improve the sealing and structural integrity of the product by accurately controlling the distance and pressing force of the pressing station 11. Accurate pressing control reduces the waste of foaming materials, improves the use efficiency of materials, and reduces production costs. In addition, the method can be widely used in the foaming operations of various products, improving the utilization rate and flexibility of the equipment.

[0119] The filling process of the foaming material is realized by using the foaming and pressing device as described above.

[0120] The electrical box 100 is implemented by using the method of using the foaming and pressing device as described above during the foaming material filling process of the electrical box 100. That is, two foaming and pressing devices are used to ensure that the foaming material is evenly filled into the foaming cavity 110 by accurately controlling the pressing force and distance, thereby improving the overall performance of the electrical box 100. The even filling of the foaming material in the foaming cavity 110 of the electrical box 100 provides a better shock absorption effect, protects the internal components from the impact and vibration, and makes the electrical box 100 more durable and reliable.

[0121] The present application provides a process of filling the foaming material into the foaming cavity 110 of the electrical box 100, which is specifically as follows:

[0122] 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 .

[0123] 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 .

[0124] 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 provided on the wall surface of the first compression plate 1 to measure the pressure on the first compression plate 1 to determine whether the electrical box 100 is compressed.

[0125] 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.

[0126] 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.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
