[0038] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] like Figure 1 As shown, in one embodiment, the hot press 100 includes a heat insulation component 10 and a body 20; the body 20 has a hot pressing chamber 201 for placing a material plate so as to hot press the material plate in the hot pressing chamber 201; the heat insulation component 10 is installed on the outer surface of the body 20 of the hot press 100 to reduce the heat radiated outward from the body 20.

[0041] During the hot pressing of the sheet metal, the temperature inside the hot pressing chamber 201 is transferred to the machine body 20 and diffuses outward from the machine body 20. By setting the heat insulation component 10, the heat radiated outward from the machine body 20 can be reduced, so that as much heat as possible is concentrated in the hot pressing chamber 201, thereby reducing energy waste and lowering energy consumption.

[0042] At the same time, this also prevents excessive heat from spreading from the machine body 20 to the workshop where it is located, thus avoiding excessive temperature rise in the workshop, improving the comfort of the operators, and preventing the workshop temperature from adversely affecting the operation of the hot press 100 or other equipment. In addition, the installation of the heat insulation component 10 also helps to improve the temperature stability inside the working cavity of the hot press 100 (i.e., the hot pressing cavity 201 described below), thereby improving the hot pressing effect.

[0043] In one embodiment, the outer surface of the body 20 includes multiple sub-surfaces, and multiple heat insulation components 10 are provided. Each sub-surface corresponds to a heat insulation component 10, and the heat insulation component 10 is connected to its corresponding sub-surface. Any sub-surface can be a planar, curved, or other shaped surface. In addition, each sub-surface can belong to a different surface in different directions of the body 20, or it can be a surface used to compose different parts of the body 20.

[0044] like Figure 2 As shown, in one embodiment, the heat insulation component 10 includes a connecting frame 1 and a first heat insulation plate 2; the connecting frame 1 is used to connect to the body 20; the first heat insulation plate 2 is connected to the connecting frame 1.

[0045] The connecting frame 1 is equivalent to a base, and the first heat insulation plate 2 is connected to the outer surface of the body 20 through the connecting frame 1. This allows the connection method of the first heat insulation plate 2 on the body 20 to be selected according to actual needs, so that the first heat insulation plate 2 has a more suitable installation method on the body 20.

[0046] In addition, during use, the connecting frame 1 is actually connected to the outer surface of the body 20.

[0047] In one embodiment, the connecting frame 1 is detachably connected to the body 20, for example, by means of bolts or other fasteners. Of course, in other embodiments, the connecting frame 1 may be non-detachable after being connected to the body 20; in this case, the connecting frame 1 may be connected to the body 20 by welding or other methods.

[0048] In one embodiment, the first heat insulation plate 2 is detachably connected to the connecting frame 1, for example, by means of bolts or other fasteners. Of course, in other embodiments, the first heat insulation plate 2 may be non-detachable after being connected to the connecting frame 1; in this case, the first heat insulation plate 2 may be connected to the connecting frame 1 by means of adhesive bonding or other methods.

[0049] like Figure 2 As shown, in one embodiment, the connecting frame 1 includes a base plate 11, which is connected to a first heat insulation plate 2. The base plate 11 is connected to the outer surface of the body 20, and the first heat insulation plate 2 is located on the side of the base plate 11 away from the body 20. After assembly, the base plate 11 is located between the first heat insulation plate 2 and the body 20. At this time, the base plate 11 can be shielded by the first heat insulation plate 2.

[0050] like Figure 2 As shown, in one embodiment, the connecting frame 1 includes a base plate 11 and a side plate 12; both the base plate 11 and the side plate 12 are connected to the first heat insulation plate 2; after assembly, the base plate 11 and the first heat insulation plate 2 are arranged along a first direction; the side plate 12 and the first heat insulation plate 2 are arranged along a second direction, wherein the first and second directions intersect. This allows the first heat insulation plate 2 to be more firmly connected to the connecting frame 1.

[0051] In one embodiment, the first direction may be perpendicular to the second direction. Wherein, in Figure 2 In this context, the first direction can be parallel to the X-axis, and the second direction can be parallel to the Y-axis. Additionally, the first direction can be left-right, and the second direction can be front-back.

[0052] like Figure 3As shown, in one embodiment, the base plate 11 includes a plurality of first connecting strips 111 and a plurality of second connecting strips 112; each first connecting strip 111 is spaced apart along a third direction; each second connecting strip 112 is spaced apart along a fourth direction; the first connecting strips 111 and each second connecting strip 112 are cross-connected; both the first connecting strips 111 and the second connecting strips 112 are connected to the first heat insulation plate 2; the third and fourth directions intersect. This ensures the supporting effect of the base plate 11 on the first heat insulation plate 2 while reducing the weight and material cost of the base plate 11.

[0053] The first connecting strip 111 and the second connecting strip 112 can be connected together by welding; or the first connecting strip 111 and the second connecting strip 112 can be connected together by bolts or other connecting parts; or the first connecting strip 111 and the second connecting strip 112 can be an integrally formed structure, for example, they can be made by punching a sheet metal.

[0054] In one embodiment, the third direction can be perpendicular to the fourth direction. The fourth direction can be the second direction described above. Figure 2 and Figure 3 Of the directions shown, the third direction is parallel to the Z-axis, and it can be the up or down direction.

[0055] In one embodiment, both the first connecting strip 111 and the second connecting strip 112 can be cuboid structures, the length direction of the first connecting strip 111 can be a fourth direction, and the length direction of the second connecting strip 112 can be a third direction.

[0056] In one embodiment, the first connecting strip 111 and the second connecting strip 112 can be stacked together to achieve their cross-setting. In this case, the area where the two are stacked together is the cross-setting area. For example, the first connecting strip 111 and the second connecting strip 112 are two independent components, which are stacked together and connected together by bolts or other connectors. Alternatively, the first connecting strip 111 and the second connecting strip 112 can also share a common area to achieve their cross-setting. For example, when a plate is punched to remove the corresponding position of the plate to prepare the base plate 11, the common area of ​​the first connecting strip 111 and the second connecting strip 112 is the cross-setting area.

[0057] In one embodiment, the side plate 12 can be connected to each of the first connecting strips 111, and can be spaced apart from the second connecting strips 112. Furthermore, in the second direction, each of the second connecting strips 112 is located on the same side of the side plate 12. Additionally, the side plate 12 can be a cuboid structure, and its length direction can be a third direction.

[0058] In one embodiment, in the second direction, the first heat insulation plate 2 may have a side plate 12 on only one side; or, in the second direction, the first heat insulation plate 2 may have side plates 12 on both sides.

[0059] In one embodiment, the side plate 12 is detachably connected to the connecting frame 1, for example, by means of bolts or other fasteners. Of course, in other embodiments, the side plate 12 may be non-detachable after being connected to the connecting frame 1, in which case the side plate 12 may be connected to the connecting frame 1 by means of adhesive bonding or other methods.

[0060] like Figure 2 As shown, in one embodiment, the heat insulation assembly 10 further includes a cover plate 3; the cover plate 3 covers the surface of the first heat insulation plate 2 facing away from the base plate 11 and is connected to the base plate 11 to press the first heat insulation plate 2 tightly against the base plate 11. The cover plate 3 can shield and protect the first heat insulation plate 2. At the same time, the cover plate 3 and the base plate 11 clamp the first heat insulation plate 2, which can also make the first heat insulation plate 2 more securely installed.

[0061] In addition, when the first heat insulation plate 2 is connected to the base plate 11 by bolts or other connecting parts, the connecting parts can pass through the cover plate 3 and the first heat insulation plate 2 in sequence and then connect to the base plate 11. In this way, the base plate 11, the first heat insulation plate 2 and the cover plate 3 can be connected together by the same connecting parts.

[0062] Specifically, the heat insulation assembly 10 also includes bolts. The cover plate 3 has a first clearance hole, the first heat insulation plate 2 has a second clearance hole, and the base plate 11 has a threaded hole. The bolt stud passes through the first and second clearance holes and is threaded into the threaded hole. The bolt nut abuts against the surface of the cover plate 3 away from the first heat insulation plate 2. At this time, the bolt can connect the base plate 11, the first heat insulation plate 2, and the cover plate 3 together.

[0063] In addition, the threaded hole is located at the intersection of the first connecting bar 111 and the second connecting bar 112. This arrangement can reduce the number of bolts while ensuring that the first heat insulation plate is connected to both the first connecting bar 111 and the second connecting bar 112 at the same time.

[0064] It should be understood that the first clearance hole penetrates the cover plate 3 along the arrangement direction of the first heat insulation plate 2 and the cover plate 3, the second clearance hole penetrates the first heat insulation plate 2 along the arrangement direction of the first heat insulation plate 2 and the cover plate 3, and the threaded hole is provided on the surface of the base plate 11 near the first heat insulation plate 2.

[0065] In one embodiment, the cover plate 3 can completely cover the first heat insulation plate 2. In this case, in an orthographic projection onto a plane perpendicular to the first direction, the projection of the surface of the first heat insulation plate 2 near the cover plate 3 is completely within the projection of the surface of the cover plate 3 near the first heat insulation plate 2.

[0066] In one embodiment, the first heat insulation plate 2 has a cavity, which reduces the weight and material cost of the entire first heat insulation plate 2.

[0067] like Figure 4 As shown, in one embodiment, the first heat insulation plate 2 includes an encapsulation component 21 and a core plate 22; the encapsulation component 21 is encapsulated on both sides of the core plate 22 in the thickness direction, and the encapsulation component 21 and the core plate 22 enclose to form a cavity.

[0068] The thickness direction of the core board 22 can be parallel to the first direction. The encapsulation component 21 helps to ensure the surface flatness and other properties of the first heat insulation board 2.

[0069] like Figure 4 As shown, in one embodiment, the core board 22 has a first surface and a second surface disposed opposite to each other in the thickness direction; the core board 22 also has a through hole 221 extending through the first surface and the second surface; the encapsulation member 21 includes a first plate 211 and a second plate 212; the first plate 211 is connected to the first surface and located between the core board 22 and the body 20; the second plate 212 is connected to the second surface and located on the side of the core board 22 opposite to the body 20. In addition, the first plate 211 closes the opening formed by the through hole 221 on the first surface, and the second plate 212 closes the opening formed by the through hole 221 on the second surface to form a cavity, that is, the two openings of the through hole 221 are closed by the first plate 211 and the second plate 212 to form a cavity.

[0070] The arrangement of the first plate 211 and the second plate 212 can prevent heat convection at the through hole 221, thereby further improving the heat insulation effect of the first heat insulation plate 2.

[0071] In one embodiment, the core board 22 has a plurality of through holes 221, and the core board 22 can be a honeycomb structure, which can ensure the strength of the core board 22 while reducing its weight and material cost. In addition, the cross-section of the through hole 221 can be a regular hexagon, and the through hole 221 is a straight hole.

[0072] In one embodiment, the axial direction of the through hole 221 is perpendicular to the outer surface of the body 20. Here, "the axial direction of the through hole 221 is perpendicular to the outer surface of the body 20" means that the axis of the through hole 221 is perpendicular to the sub-surface of the first heat insulation plate 2 having the through hole 221, wherein the axis of the through hole 221 is a straight line and the sub-surface is a plane.

[0073] In one embodiment, the core board 22, the first board 211, and the second board 212 can all be made of non-metallic materials, such as paper. This reduces costs. In this case, the outer surface of the first insulation board 2 is also coated with a waterproof layer, such as a phenolic resin layer. The outer surface of the first insulation board 2 includes at least a portion of the outer surface of the first board 211, at least a portion of the outer surface of the second board 212, and at least a portion of the outer surface of the core board 22.

[0074] In one embodiment, the heat insulation assembly 10 includes a plurality of first heat insulation panels 2, each of which is connected to the connecting frame 1; heat insulation filler is filled between adjacent first heat insulation panels 2. Compared with the arrangement of each first heat insulation panel 2 as a single panel, the arrangement in this embodiment makes the size and weight of each first heat insulation panel 2 smaller, which facilitates handling and installation during operation.

[0075] In addition, filling the gaps between adjacent first insulation panels 2 with heat insulation filler can prevent heat leakage from the gaps between adjacent first insulation panels 2 and improve the heat insulation effect.

[0076] In addition, the insulation filler can be aluminum silicate fiber. Of course, other existing designs can also be used for the insulation filler.

[0077] It should be noted that each of the first heat insulation panels 2 includes the first panel 211, the second panel 212, and the core panel 22 mentioned above.

[0078] like Figure 5 and Figure 6 As shown, in one embodiment, the hot press 100 further includes a movable platform 30, a drive assembly 50, and a plurality of hot press plates 60; the movable platform 30 and the hot press plates 60 are both located within the hot press cavity 201; each hot press plate 60 is arranged sequentially along the pressing direction of the hot press 100; in the pressing direction, each hot press plate 60 is arranged on the same side of the movable platform 30, and the movable platform 30 is connected to the hot press plate 60 closest to it (defined as the first hot press plate); the drive assembly 50 is connected to the movable platform 30 and is used to drive the movable platform 30 to reciprocate along the pressing direction.

[0079] When the movable platform 30 moves along the pressing direction, it can push the hot press plates 60 closer together, thereby achieving hot pressing of the sheet material placed on each hot press plate 60. Furthermore, the pressing direction can be parallel to a third direction. When the third direction is vertical, each hot press plate 60 is located above the movable platform 30, with the first hot press plate being the lowest hot press plate 60.

[0080] like Figure 5 and Figure 6As shown, in one embodiment, the hot press 100 further includes a second heat insulation plate 40, which is located in the hot pressing chamber 201 and is connected between the movable platform 30 and the hot pressing plate 60 (i.e., the first hot pressing plate) closest to the movable platform 30 in the pressing direction.

[0081] The installation of the second heat insulation plate 40 can reduce the heat transfer from the first hot plate to the moving platform 30, thereby reducing heat leakage to the outside through the moving platform 30 and the drive assembly 50.

[0082] In one embodiment, the material of the second heat insulation plate 40 can be a thermosetting resin that is resistant to high temperature and high pressure. Of course, the material of the second heat insulation plate 40 can also be other existing designs.

[0083] like Figure 5 and Figure 6 As shown, in one embodiment, the hot press 100 further includes a third heat insulation plate 70, which is located within the hot pressing chamber 201. In the pressing direction, the third heat insulation plate 70 connects the machine body 20 and the hot pressing plate 60 furthest from the movable platform 30 (defined as the second hot pressing plate). The third heat insulation plate 70 reduces the heat transfer from the second hot pressing plate to the machine body 20, thereby reducing heat leakage through the machine body 20.

[0084] The third heat insulation plate 70 is located inside the hot pressing cavity 201. When the pressing direction is up and down, the second hot pressing plate is the uppermost hot pressing plate 60, and the third heat insulation plate 70 is located above the second hot pressing plate.

[0085] In addition, the material of the third heat insulation panel 70 can be the same as that of the second heat insulation panel 40.

[0086] When the drive assembly 50 drives the active platform to move upward, the first hot press plate can move upward, and eventually the sheet material between the first hot press plate and the second hot press plate is pressed together by the first hot press plate and the second hot press plate to perform the hot pressing operation.

[0087] The number of hot press plates 60 can be two or more. When the number of hot press plates 60 is more than two, there are other hot press plates between the first and second hot press plates. The hot press plate 60 located between the first and second hot press plates is defined as the third hot press plate. The third hot press plate can move relative to the machine body along the pressing direction. The connection method between the third hot press plate and the machine body 20 can be an existing design.

[0088] like Figure 5 and Figure 6As shown, in one embodiment, the body 20 includes a first support plate 202, a second support plate 203, a third support plate 204, a fourth support plate 205, a vacuum chamber 206, a first chamber door 207, and a second chamber door 208.

[0089] The first support plate 202 and the second support plate 203 are spaced apart along a first direction. The third support plate 204 and the fourth support plate 205 are spaced apart between the first support plate 202 and the second support plate 203 along a third direction, and are both connected to the first support plate 202 and the second support plate 203 to enclose and form a receiving cavity with open ends; in addition, the first support plate 202, the second support plate 203, the third support plate 204 and the fourth support plate 205 are connected to form a frame, and the receiving cavity penetrates the frame along a second direction.

[0090] Vacuum chamber 206 is connected to first support plate 202, second support plate 203, third support plate 204, and fourth support plate 205. Vacuum chamber 206 and frame are arranged along a second direction. Vacuum chamber 206 has a vacuum cavity that extends through it along the second direction and communicates with the receiving cavity. First door 207 is connected to the side of vacuum chamber 206 away from frame and is used to close the opening at the end of vacuum cavity away from receiving cavity (defined as the first opening). Second door 208 is connected to the side of frame away from vacuum chamber 206 and is used to close the opening at the end of receiving cavity away from vacuum cavity (defined as the second opening).

[0091] When the first door 207 closes the first opening and the second door 208 closes the second opening, the first support plate 202, the second support plate 203, the third support plate 204, the fourth support plate 205, the vacuum chamber 206, the first door 207, and the second door 208 enclose and form a thermocompression chamber 201.

[0092] In addition, the hot press plate 60, the second heat insulation plate 40, the third heat insulation plate 70, and the movable platform 30 are all located inside the receiving cavity.
