Description

Technical Field

[0001] This invention relates to the field of metal mesh forming, and more specifically, to a mold and forming process for coating the four sides of a metal mesh with adhesive. Background Technology

[0002] When applying adhesive to the perimeter of a metal mesh panel, it's desirable to apply it only to the desired areas. However, due to the dense mesh openings, excess burrs are particularly difficult to remove. Using traditional molds and molding processes, the excess burrs are squeezed into the mesh openings. After vulcanization, the mesh is filled with vulcanized rubber, requiring each opening to be meticulously cleaned with a needle. This method of burr removal is extremely inefficient, significantly reducing production efficiency and increasing production costs.

[0003] In view of this, the present invention is hereby proposed. Summary of the Invention

[0004] The purpose of this invention is to propose a mold and molding process for coating the four sides of a metal mesh plate with rubber, in order to solve the problem that in the existing technology, when using traditional molds and molding processes, all the excess flash is squeezed into the mesh holes. After vulcanization, the mesh holes are full of vulcanized rubber, which needs to be cleaned hole by hole with a needle. This process is very inefficient in cleaning flash and greatly reduces production efficiency.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A mold for coating the four sides of a metal mesh sheet with adhesive, the mold comprising an upper mold plate and a lower mold plate, the upper mold plate and the lower mold plate being closed to form an integral cavity for placing the metal mesh sheet, an external adhesive overflow groove being provided on the outer side of the integral cavity, and an internal adhesive overflow groove being provided on the inner side of the integral cavity, the volume of the internal adhesive overflow groove being V1, the volume of the flash being V2, and V1>V2.

[0007] The present invention discloses a mold for coating the four sides of a metal mesh plate with glue. An inner overflow groove is provided on the inner side of the overall cavity, and the volume of the inner overflow groove is larger than the volume of the flash. This prevents the excess flash from being squeezed into the mesh of the metal mesh plate, which greatly improves production efficiency and reduces production costs.

[0008] Furthermore, the inner overflow groove includes a first overflow groove and a second overflow groove, which are respectively arranged in a first overflow groove and a second overflow groove. The first overflow groove is arranged on the upper template, and the second overflow groove and the outer overflow groove are arranged on the lower template.

[0009] Furthermore, a first cavity is provided below the upper template, and a second cavity is provided above the lower template. The first cavity and the second cavity are combined to form an integral cavity. The first overflow groove is provided inside the first cavity; the second overflow groove is provided inside the second cavity; and the external overflow groove is provided outside the second cavity.

[0010] Furthermore, the first cavity includes a first mesh cavity and a first frame cavity, and the first glue overflow groove is provided between the first mesh cavity and the first frame cavity; the second cavity includes a second mesh cavity and a second frame cavity, and the second glue overflow groove is provided between the second mesh cavity and the second frame cavity.

[0011] Furthermore, a protruding edge is provided between the first overflow groove and the first frame cavity, and a groove is provided between the second overflow groove and the second frame cavity, with the protruding edge corresponding to the groove.

[0012] Furthermore, a magnetic telescopic assembly is installed inside the second mesh cavity of the lower template.

[0013] Furthermore, the metal mesh plate includes a metal frame portion and a mesh portion.

[0014] In a second aspect, the present invention provides a molding process for coating the four sides of a metal mesh plate with adhesive. The molding process for coating the four sides of a metal mesh plate uses any one of the molds described in the present invention, and includes the following steps:

[0015] S1. A rubber extruder extrudes pre-formed rubber strips;

[0016] S2. Pre-treatment of the rubber strip: Cut and weigh the rubber strip to ensure that the length and quality of the rubber strip meet the requirements.

[0017] S3. After the mold is preheated, place half of the rubber strip into the second frame cavity of the second cavity of the lower mold plate.

[0018] S4. Then install the metal mesh plate into the second cavity;

[0019] S5. Then place the other half of the adhesive strip on top of the metal mesh plate, symmetrically arranged with the other half of the adhesive strip in step S3.

[0020] S6. Mold closing and vulcanization; After vulcanization, remove the product and tear off any excess flash by hand.

[0021] The molding process for coating the metal mesh with adhesive around its perimeter as described in this invention involves extruding and pre-forming the adhesive strip using a rubber extruder. This allows for precise control of the weight, shape, and size of the adhesive strip, thereby precisely controlling the flash of the product and ensuring that the volume of the flash does not exceed the volume of the inner overflow groove. Consequently, excess flash is prevented from being squeezed into the mesh openings of the metal mesh, greatly improving production efficiency and reducing production costs.

[0022] Furthermore, in step S3, the mold is preheated to 150-160°C.

[0023] Furthermore, in step S6, the vulcanization temperature is 160–180°C, the vulcanization pressure is 7–10 MPa, and the vulcanization time is 5–8 min.

[0024] This invention proposes a mold and forming process for coating the four sides of a metal mesh panel with adhesive. Compared with the prior art, the mold and forming process for coating the four sides of a metal mesh panel described in this invention has the following advantages:

[0025] Beneficial effects:

[0026] 1) The mold and forming process for coating the four sides of a metal mesh plate according to the present invention provides an inner overflow groove on the inner side of the overall cavity, and the volume of the inner overflow groove is larger than the volume of the flash, so that the excess flash will not be squeezed into the mesh of the metal mesh plate, which greatly improves production efficiency and increases production cost.

[0027] 2) The mold and forming process for coating the four sides of a metal mesh plate according to the present invention uses a rubber extruder for pre-forming. The resulting rubber strip can be precisely controlled in terms of weight, shape and size, thereby precisely controlling the flash of the product so that the volume of the flash does not exceed the volume of the inner overflow groove. This prevents excess flash from being squeezed into the mesh of the metal mesh plate, greatly improving production efficiency and reducing production costs. Attached Figure Description

[0041] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] Example 1

[0043] like Figures 1-10 As shown, this embodiment proposes a mold 100 for coating the four sides of a metal mesh plate with adhesive, such as... Figure 1 and Figure 2 As shown, the mold 100 for wrapping the metal mesh plate with adhesive around its edges includes an upper mold plate 1 and a lower mold plate 2. When the upper mold plate 1 and the lower mold plate 2 are closed, they form an integral cavity for placing the metal mesh plate 3. Figure 3 As shown, an overflow groove 8 is provided on the outside of the integral cavity, and an inner overflow groove 5 is provided on the inside of the integral cavity. The volume of the inner overflow groove 5 is V1, and the volume of the flash is V2, where V1>V2.

[0044] The mold 100 for wrapping the metal mesh plate with glue on all four sides described in this embodiment has an inner overflow groove 5 on the inner side of the overall cavity, and the volume V1 of the inner overflow groove 5 is greater than the volume V2 of the flash, so that the excess flash will not be squeezed into the mesh part 32 of the metal mesh plate 3, which greatly improves production efficiency and increases production cost.

[0045] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the inner overflow groove 5 includes a first overflow groove 51 and a second overflow groove 52. The first overflow groove 51 and the second overflow groove 52 are respectively arranged. The first overflow groove 51 is arranged on the upper template 1, and the second overflow groove 52 and the outer overflow groove 8 are arranged on the lower template 2.

[0046] Specifically, such as Figure 3 and Figure 5 As shown, a first cavity 11 is provided below the upper template 1, and a second cavity 21 is provided above the lower template 2. The first cavity 11 and the second cavity 21 are combined to form an integral cavity. The first overflow groove 51 is provided inside the first cavity 11; the second overflow groove 52 is provided inside the second cavity 21, and the external overflow groove 8 is provided outside the second cavity 21.

[0047] Specifically, such as Figure 2 As shown, the metal mesh plate 3 includes a metal frame portion 31 and a mesh portion 32, as... Figure 5 As shown, the first cavity 11 includes a first mesh cavity 111 and a first frame cavity 112, and the first overflow groove 51 is provided between the first mesh cavity 111 and the first frame cavity 112; as shown Figure 3As shown, the second cavity 21 includes a second mesh cavity 211 and a second frame cavity 212, and the second overflow groove 52 is provided between the second mesh cavity 211 and the second frame cavity 212.

[0048] Specifically, such as Figure 6 As shown, a protruding edge 6 is provided between the first overflow groove 51 and the first frame cavity 112, such as... Figure 4 As shown, a groove 7 is provided between the second overflow groove 52 and the second frame cavity 212, and the protruding edge 6 is provided correspondingly to the groove 7.

[0049] Specifically, such as Figure 7 As shown, a magnetic telescopic assembly 9 is installed in the second mesh cavity 211 of the lower template 2.

[0050] Specifically, such as Figure 8 As shown, a mesh plate balancing sensing device 4 is installed below the lower template 2.

[0051] When the metal mesh plate 3 is installed in the second cavity 21, the mesh plate balance sensing device 4 is used to control the magnet telescopic assembly 9 to extend fully. At this time, the magnet telescopic assembly 9 is used to position the installation of the metal mesh plate 3, which facilitates the installation of the metal mesh plate 3 without damaging it, and greatly improves the installation efficiency of the metal mesh plate 3.

[0052] During mold clamping and vulcanization, the metal mesh plate balance sensing device 4 is used to sense the balance state of the metal mesh plate 3 and adjust the magnitude of the current that triggers the extension and retraction of the magnet telescopic assembly 9 to regulate the extension or retraction of the magnet telescopic assembly 9. The magnitude of the attraction force generated when the magnet telescopic assembly 9 is extended is different from that when it is retracted; the attraction force generated when the magnet telescopic assembly 9 is extended is greater than that when it is retracted.

[0053] More specifically, such as Figure 9 and Figure 10 As shown, the mesh plate balance sensing device 4 includes a central sphere 41 located at the center of the bottom of the lower template 2, a plane 42 supporting the central sphere 41, and a sliding resistor 43 arranged along a line connecting the central sphere 41 and the corresponding direction of the magnetic telescopic assembly 9. The sliding resistor 43 includes a sliding part 431 and a stationary part 432. The sliding part 431 is sleeved on the outside of the stationary part 432, and the outer end of the sliding part 431 is connected to the central sphere 41. The number of sliding resistors 43 is the same as the number of magnetic telescopic assemblies 9, and the sliding resistors 43 are connected in series with the circuit that triggers the extension and retraction of the magnetic telescopic assembly 9. The mesh plate balance sensing device 4 allows for rapid and accurate control of the current in the magnetic telescopic assembly 9.

[0054] In this embodiment, the number of the magnet telescopic assembly 9 and the sliding resistor 43 is set to four sets.

[0055] This embodiment also proposes a molding process for coating the four sides of a metal mesh plate with adhesive. The molding process for coating the four sides of a metal mesh plate uses any of the molds 100 described above for coating the four sides of a metal mesh plate, and the molding process for coating the four sides of a metal mesh plate with adhesive includes the following steps:

[0056] S1. A rubber extruder extrudes pre-formed rubber strips;

[0057] S2. Pre-treatment of the rubber strip: Cut and weigh the rubber strip to ensure that the length and quality of the rubber strip meet the requirements.

[0058] S3. After the mold 100 is preheated, place half of the rubber strip into the second frame cavity 212 of the second cavity 21 of the lower mold 2.

[0059] S4. Then install the metal mesh plate 3 into the second cavity 21;

[0060] S5. Then place the other half of the adhesive strip on top of the metal mesh plate 3, symmetrically arranged with the other half of the adhesive strip in step S3.

[0061] S6. Mold closing and vulcanization; After vulcanization, remove the product and tear off any excess flash by hand.

[0062] In the molding process of wrapping the metal mesh plate around its perimeter described in this embodiment, the rubber strip is pre-formed by extruding using a rubber extruder. This allows for precise control of the weight, shape, and size of the rubber strip, thereby precisely controlling the flash of the product. This ensures that the volume of the flash, V2, does not exceed the volume V1 of the inner overflow groove 5. Consequently, excess flash is prevented from being squeezed into the mesh openings of the metal mesh plate, greatly improving production efficiency and reducing production costs.

[0063] In step S3, the mold 100 is preheated to 150-160°C. This setting makes the flash after vulcanization very easy to clean; it can be easily torn off by hand.

[0064] In step S6, the vulcanization temperature is 160–180°C, the vulcanization pressure is 7–10 MPa, and the vulcanization time is 5–8 minutes. This setting makes the flash after vulcanization very easy to clean; it can be easily torn off by hand.

[0065] In step S2, the pretreatment of the adhesive strips, including cutting and weighing the adhesive strips to ensure that the length and quality of the adhesive strips meet the requirements, includes the following steps: the length tolerance of the adhesive strips is ±3mm; each cut adhesive strip is weighed, and adhesive strips that meet the quality requirements are selected, with a quality tolerance of ±8g.

[0066] In the molding process of wrapping the metal mesh plate around the perimeter described in this embodiment, the rubber strip is pre-formed by extruding using a rubber extruder. This allows for precise control of the weight, shape, and size of the rubber strip, thereby precisely controlling the flash of the product and ensuring that the volume of the flash does not exceed the volume of the inner overflow groove 5. Consequently, excess flash is not squeezed into the mesh of the metal mesh plate 3, greatly improving production efficiency and reducing production costs.

[0067] In this embodiment, the mass m1 of the adhesive coating around the metal mesh plate 3 is constant. Assuming the mass of the burr is m2, where m2 = m1 * 10%, then the total mass of the adhesive strip is m = m1 + m2. Since the adhesive strip is extruded, its density ρ is constant, so m = ρ * v. Furthermore, the shape of the adhesive strip is consistent, meaning its cross-sectional area s is constant, so v = s * l. Therefore, the mass m of the adhesive strip can be determined based on its length.

[0068] In this embodiment, the volume of the inner overflow glue tank 5 is V1, which is calculated based on the length, width, and height of the inner overflow glue tank 5; the volume of the flash is V2 = m2 / ρ.

[0069] In step S4, when the metal mesh plate 3 is installed in the second cavity 21, the mesh plate balance sensing device 4 is used to control the magnet telescopic assembly 9 to extend fully. At this time, the magnet telescopic assembly 9 is used to position the installation of the metal mesh plate 3, which facilitates the installation of the metal mesh plate 3 without damaging it, and greatly improves the installation efficiency of the metal mesh plate 3.

[0070] During the mold closing and vulcanization process in step S6, under normal conditions, the metal mesh plate 3 will be completely flattened in the second cavity 21 of the lower mold plate 2 under the action of vulcanization pressure. When a part of the metal mesh plate 3 protrudes, it will cause an imbalance of the metal mesh plate 3. Therefore, the mesh plate balance sensing device 4 is used to sense the balance state of the metal mesh plate 3 and adjust the magnitude of the current that triggers the extension and retraction of the magnet extension and retraction assembly 9 to adjust the extension or retraction of the magnet extension and retraction assembly 9, so as to ensure that the metal mesh plate 3 maintains a completely flattened balance state during the mold closing and vulcanization process.

[0071] When the metal mesh plate 3 becomes unbalanced during the mold clamping and vulcanization process, the mesh plate balance sensing device 4 controls the central ball 41 to tilt and slide to one side, pushing the sliding part 431 of the sliding resistor 43 on the tilted side to slide towards the stationary part 432, thus reducing the resistance; the sliding part 431 of the sliding resistor 43 on the other side slides outward towards the stationary part 432, thus increasing the resistance; thereby, the current through the corresponding magnetic telescopic components 9 increases and decreases, causing the magnetic telescopic components 9 on the tilted side to elongate and the magnetic telescopic components 9 on the other side to shorten; it can be seen that after the central ball 41 slides, it has a different degree of elongation-promoting effect on multiple magnetic telescopic components 9 on the tilted side, and a different degree of shortening-promoting effect on multiple magnetic telescopic components 9 on the other side of the tilted direction; thus ensuring that the metal mesh plate 3 maintains a completely flat and balanced state during the mold clamping and vulcanization process, thereby improving the balance stability of the metal mesh plate 3 during the mold clamping and vulcanization process.

[0072] In this invention, the mold 100 for coating the metal mesh with adhesive around its edges and the molding process for coating the metal mesh with adhesive around its edges are interconnected and inseparable, thus cleverly achieving multiple functions.

[0073] 1. An inner overflow groove 5 is provided on the inner side of the integral cavity, and the volume of the inner overflow groove 5 is larger than the volume of the flash, so that the excess flash will not be squeezed into the mesh of the metal mesh plate 3, which greatly improves production efficiency and increases production cost.

[0074] Second, the rubber strip is pre-formed by extrusion using a rubber extruder. This allows for precise control of the weight, shape, and size of the rubber strip, thereby precisely controlling the flash of the product and ensuring that the volume of the flash does not exceed the volume of the inner overflow groove 5. This prevents excess flash from being squeezed into the mesh of the metal mesh plate 3, greatly improving production efficiency and reducing production costs.

[0075] Third, the magnetic telescopic assembly 9 and the metal mesh plate balance sensing device 4 are interconnected and inseparable. On the one hand, in step S4, when the metal mesh plate 3 is installed in the second cavity 21, the metal mesh plate balance sensing device 4 is used to control the magnetic telescopic assembly 9 to fully extend. At this time, the magnetic telescopic assembly 9 is used to position the installation of the metal mesh plate 3, facilitating the installation of the metal mesh plate 3 without damaging it, and greatly improving the installation efficiency of the metal mesh plate 3. On the other hand, during the mold closing and vulcanization in step S6, when a part of the metal mesh plate 3 protrudes, it will cause an imbalance in the metal mesh plate 3. Therefore, the metal mesh plate balance sensing device 4 is used to sense the balance state of the metal mesh plate 3 and adjust the magnitude of the current that triggers the extension and retraction of the magnetic telescopic assembly 9 to adjust the extension or retraction of the magnetic telescopic assembly 9, ensuring that the metal mesh plate 3 maintains a fully flattened balance state during the mold closing and vulcanization process, thereby improving the balance stability of the metal mesh plate 3 during the mold closing and vulcanization process, and enabling the mold closing and vulcanization to proceed smoothly.

[0076] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
