DETAILED DESCRIPTION

[0024] The following is the specific embodiment of the present application and in conjunction with the accompanying drawings, the technical scheme of the present application is further described, but the present application is not limited to these embodiments. In the following description, specific details such as specific configuration and components are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the protection scope of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.

[0026] The present application provides a foaming molding mold, which can be an upper mold or a lower mold. During the foaming molding process, the upper mold and the lower mold form a cavity after the mold is closed. It should be understood that the molding mold needs to be designed according to the required product shape for molding various products. The molding mold includes an upper mold and a lower mold. In an embodiment of the present application, the upper mold is fixedly connected to a movable seat, and the lower mold is fixedly connected to a base. When the mold is closed, the driving device drives the movable seat to flip downward, and the movable seat drives the upper mold to flip downward to achieve mold closing, so that the foaming material is molded and solidified; when the mold is opened, the driving device drives the movable seat to flip upward, and the movable seat drives the upper mold to flip upward away from the lower mold.

[0027] In an embodiment of the present application, the foaming molding mold includes a concrete structure, a resin structure layer, and a fiberglass structural layer; the fiberglass structural layer is arranged on the concrete structure; the resin structure layer is arranged on the fiberglass structural layer; the resin structure layer is located on the inner side of the mold to constitute the molding surface of the mold; aluminum profiles are embedded in the resin structure layer and the fiberglass structural layer, and the length extension direction of the aluminum profile is consistent with the length direction of the molding surface; on the cross section of the foaming molding mold, a plurality of aluminum profiles are arranged in sequence and spaced apart along the extension direction of the contour line formed by the molding surface on the cross section, and the aluminum profiles are provided with a heat dissipation structure and a guide hole; the heat dissipation structure is located in the resin structure layer, and the guide hole is located on the side of the heat dissipation structure away from the molding surface; on the cross section of the foaming molding mold, the heat dissipation structure is in the shape of a long strip, and its extension direction is consistent with the extension direction of the contour line formed along the molding surface on the cross section.

[0028] Based on the above foaming molding mold, the foaming molding mold mainly includes a three-layer structure, a concrete structure, a resin structure layer, and a glass fiber reinforced plastic structure layer, and the glass fiber reinforced plastic structure layer is arranged on the concrete structure; the resin structure layer is arranged on the glass fiber reinforced plastic structure layer; the resin structure layer is located on the inner side of the mold to form the molding surface of the mold; and the aluminum profile is embedded in the resin structure layer and the glass fiber reinforced plastic structure layer. Further, along the extension direction of the contour line formed on the cross section of the molding surface, a plurality of aluminum profiles are arranged in sequence and spaced apart, and the aluminum profile is provided with a heat dissipation structure and a guide hole, and the heat dissipation structure is in a long strip shape, and its extension direction is consistent with the extension direction of the contour line formed on the cross section of the molding surface. When hot water is introduced into the guide hole, the heat of the hot water can be dissipated through the aluminum profile, and the molding surface is evenly heated to the required temperature. The long strip heat dissipation structure on the aluminum profile can transfer heat evenly to the above contour line, so that the temperature of each position of the molding surface is consistent. Therefore, with the arrangement of the above aluminum profile, heat can be transferred to the molding surface more evenly, and the quality of foaming molding can be guaranteed.

[0029] Furthermore, the glass fiber reinforced plastic structure layer is located between the concrete structure and the resin structure layer, serving as a transition and reinforcement structure layer, and is provided on the concrete structure as a carrier of the resin structure layer. Therefore, the above mold adopts a multi-layer composite structure, which is lighter, lower in cost, longer in life, and more convenient to carry.

[0030] It should be understood that a set of foaming molds includes an upper mold and a lower mold. Figure 1 and Figure 2 They are the lower mold and the upper mold, and both can use the structure of the foaming molding mold provided in the embodiment of the present application.

[0031] refer to Figure 3-Figure 5 In one embodiment of the present application, the foaming molding mold includes: a concrete structure 10, a resin structure layer 20, and a glass fiber reinforced plastic structure layer 30; the glass fiber reinforced plastic structure layer 30 is arranged on the concrete structure 10; the resin structure layer 20 is arranged on the glass fiber reinforced plastic structure layer 30; the resin structure layer 20 is located on the inner side of the mold to constitute a molding surface 211 of the mold; an aluminum profile 40 is embedded in the resin structure layer 20 and the glass fiber reinforced plastic structure layer 30, and the length extension direction of the aluminum profile 40 is consistent with the length direction of the molding surface 211. On the cross section of the foaming molding mold, a plurality of aluminum profiles 40 are arranged in sequence and spaced apart along the extension direction of the contour line 212 formed by the molding surface 211 on the cross section, and the aluminum profiles 40 are provided with a heat dissipation structure 41 and a guide hole 42; the heat dissipation structure 41 is located in the resin structure layer 20, and the guide hole 42 is located on the side of the heat dissipation structure 41 away from the molding surface 211; on the cross section of the foaming molding mold, the heat dissipation structure 41 is in the shape of a long strip, and its extension direction is consistent with the extension direction of the contour line 212 formed along the molding surface 211 on the cross section.

[0032] exist Figure 3 In the structure shown, the heat dissipation structures 41 of each aluminum profile 40 are distributed on the entire contour line 212 of the molding surface 211. When hot water passes through the guide holes 42 of the aluminum profile 40, the aluminum profile 40 is heated, and its heat can be evenly transferred to the molding surface 211 through the heat dissipation structure 41, so that the temperature of each part of the molding surface 211 is roughly the same, thereby improving the quality of foaming molding. In addition, the glass fiber reinforced plastic structure layer 30 can provide high-strength support, which can reduce the requirements for the thickness of concrete.

[0033] In one embodiment of the present application, the resin structure layer 20 includes a resin surface layer 21 and a resin inner layer 22, wherein the resin surface layer 21 is close to the molding surface 211, and the resin inner layer 22 is close to the glass fiber reinforced plastic structure layer 30; aluminum powder is added to the resin inner layer 22. The molding surface 211 is formed on the resin surface layer 21, and has good finish and high hardness; adding aluminum powder to the resin inner layer 22 can increase thermal conductivity, facilitate heat transfer of the aluminum profile 40, and ensure temperature uniformity on the molding surface 211.

[0034] refer to Figure 4 and Figure 5 In one embodiment of the present application, a plurality of protrusions 44 are provided on the heat dissipation structure 41 in the cross section of the foaming mold. The curved surface on the protrusion 44 can increase the contact area between the heat dissipation structure 41 and the resin structure layer 20, thereby facilitating the transfer of heat from the heat dissipation structure 41 of the aluminum profile to the resin structure layer 20. Figure 4 In the structure shown, five protrusions 44 are arranged on the heat dissipation structure 41 of the aluminum profile; Figure 5 In the structure shown, four protrusions 44 are arranged on the heat dissipation structure 41 of the aluminum profile.

[0035] Continue to refer Figure 4 and Figure 5 In one embodiment of the present application, on the cross section of the foaming mold, the aluminum profile 40 is provided with a T-slot 45 on the side close to the concrete structure 10; the guide hole 42 is arranged between the heat dissipation structure 41 and the T-slot 45. The foaming mold also includes a connecting bolt 50, and the head 51 of the connecting bolt 50 is inserted into the T-slot 45 and confined, and the screw 52 of the connecting bolt 50 passes through the T-slot 45 and passes through the FRP structural layer 30 to enter the concrete structure 10 to achieve connection. Specifically, the head 51 of the connecting bolt 50 is located in the T-slot 45, is confined by the T-slot 45, and cannot be disengaged, and the screw 52 passes through the opening of the T-slot 45 and passes through the FRP structural layer 30 to enter the concrete structure 10, thereby forming a connection between the concrete structure 10 and the aluminum profile 40.

[0036] In one embodiment of the present application, a vacuum hole for connecting to a vacuuming device is provided in one or more aluminum profiles 40; the vacuum hole is parallel to the guide hole 42 on the same profile; the vacuum hole is connected to the molding surface 211 through an elongated connecting hole, so as to realize vacuuming of the internal space of the mold. When the vacuuming device extracts the air in the vacuum hole, the air in the molding cavity of the mold is sucked into the vacuum hole through the connecting hole, thereby forming a negative pressure in the molding cavity of the mold, and the formed negative pressure can be used to adsorb the surface material of the foamed part on the molding surface 211, for example, leather.

[0037] In one embodiment of the present application, a plurality of guide holes 42 are arranged on at least part of the aluminum profile 40, and the positions of the guide holes 42 are distributed at different positions along the contour line 212 formed by the molding surface 211 on the cross section. The number of guide holes 42 can be determined according to the length of the heat dissipation structure 41. When the heat dissipation structure 41 reaches a certain length, a plurality of guide holes 42 can be arranged on the back thereof to provide heat. Figure 5 In the structure shown, two guide holes 42 are provided on the aluminum profile 40; Figure 4 In the structure shown, an air guide hole 42 is provided on the aluminum profile 40 .

[0038] In one embodiment of the present application, in the cross section of the foaming molding mold, at least part of the curved portion of the contour line 212 of the molding surface 211, the heat dissipation structure 41 of the aluminum profile 40 is configured to be curved and adapted to the shape of the curved portion 212a. Figure 5 In the structure shown, the contour line 212 of the molding surface 211 has a curved portion 212a, and the heat dissipation structure 41 of the aluminum profile 40 is adapted to the shape of the curved portion 212a. In addition, in one embodiment of the present application, in the cross section of the foaming molding mold, the heat dissipation structure 41 of a portion of the aluminum profile 40 is linear. Figure 4 In the structure shown, the contour line 212 of the molding surface 211 extends approximately in a straight line, and the heat dissipation structure 41 of the aluminum profile 40 is also in a straight line shape, extending in the same direction as the contour line 212 .

[0039] In one embodiment of the present application, the foaming mold is divided into a plurality of mold units in the length direction, and each mold unit is provided with a water inlet and a water outlet. Specifically, as the hot water in the guide hole dissipates the heat in the hot water during the transportation process, its temperature gradually decreases. When the transportation length is too long, the hot water in the guide hole will experience a large temperature drop. To this end, the foaming mold is divided into a plurality of mold units in the length direction, and each mold unit is provided with a water inlet and a water outlet, so as to control the length of a single hot water transportation, control the hot water temperature difference at the water inlet and the water outlet within a predetermined range, prevent a large temperature difference, and ensure that the temperature of the molding surface at various locations in the length direction is roughly the same.

[0040] It should be noted that the foaming molding mold provided in the present application can be adapted to the molding of large foam parts, for example, interior decoration structures in the compartments of public transportation vehicles.

[0041] The embodiment of the present application also provides a foaming part production equipment, including the foaming molding mold provided in the previous part.

When hot water is introduced into the guide hole, the heat of the hot water can be dissipated through the aluminum profile, and the molding surface is evenly heated to the desired temperature. The long strip heat dissipation structure on the aluminum profile can evenly transfer heat to the above-mentioned contour line, so that the temperature of each position of the molding surface remains consistent. Therefore, with the help of the above-mentioned arrangement of aluminum profiles, heat can be transferred to the molding surface more evenly, thereby ensuring the quality of foaming molding.
