DETAILED DESCRIPTION

[0028] It should be noted that the embodiments and technical features in the present application can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as an explanation and description of the purpose of the present application, and should not be regarded as an improper limitation of the present application.

[0029] The present application will be described in further detail below with reference to the accompanying drawings and specific embodiments. The "first", "second", and the like in the embodiments of the present application are only for the purpose of description, and should not be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "a plurality of" is at least two, such as two, three, and the like, unless otherwise explicitly specified.

[0030] In order to better understand the inner positioning device 100 of the press-in die provided by the present application, the press-in die will be described first.

[0031] The embodiments of the present application provide a press-in die, and the press-in die comprises the inner positioning device 100 in any one of the embodiments described below.

[0032] For example, the press-in die further comprises an inner die plate and an outer die plate, one of the inner die plate and the outer die plate is a male die, the other of the inner die plate and the outer die plate is a female die, and two or more plate materials to be connected can be placed between the male die and the female die, and then a pressure device can be used to apply pressure to the male die, and the two or more plate materials to be connected are connected by cold extrusion deformation of the plate material.

[0033] ​Another embodiment of this application discloses an internal positioning device 100 for a riveting die, applied to a cooking device. The cooking device includes a panel and a housing. The housing has an inner cavity and a through opening communicating with the inner cavity. The panel covers the through opening. The riveting die rivets the housing and the panel together using a pressure device. Please refer to... Figures 1 to 4 The internal positioning device 100 includes a fixing block 1 and an internal support assembly 2. The fixing block 1 is disposed in the inner template of the riveting mold. Part of the internal support assembly 2 is disposed in the fixing block 1, and the other part of the internal support assembly 2 is telescopically disposed to extend to abut against the cavity wall of the inner cavity or retract away from the cavity wall of the inner cavity.

[0034] The internal positioning device 100 of the riveting die provided in this application embodiment sets a fixing block 1 on the inner template of the riveting die, and a portion of the inner support component 2 is set on the fixing block 1. The other portion of the inner support component 2 is telescopically configurable. In this way, when the box is fitted onto the internal positioning device 100 for riveting, the other portion of the inner support component 2 can be moved to retract away from the cavity wall of the inner cavity. This reduces the possibility of collision and scratches between the cavity wall of the inner cavity and the inner support component 2, which could lead to a decrease in product yield, thereby improving the aesthetics of the cavity wall and the product qualification rate. After the box is fitted onto the internal positioning device 100, the other portion of the inner support component 2 can be moved to approach and abut against the cavity wall of the inner cavity. This not only provides accurate positioning for the inner template during the riveting process, reducing the possibility of misalignment due to positioning failure, but also effectively supports the cavity wall, reducing the possibility of cavity distortion and deformation during riveting, further improving the yield rate.

[0035] The riveting mold provided in this application embodiment, based on the advantages of the internal positioning device 100 described above, also has the advantages of reducing damage to the cavity wall and having a high yield rate.

[0036] For example, in one embodiment, the cooking device may be a microwave oven, an oven, or a steamer, etc.

[0037] For example, in one embodiment, the first direction may be the vertical direction or the front-back direction of the cavity.

[0038] It should be noted that "up" refers to the direction towards the ceiling, and "down" is the opposite of "up." The up-down, front-back, and left-right directions are perpendicular to each other, forming a three-dimensional vertical coordinate system.

[0039] In one exemplary embodiment, Figure 1 R1 can be the thickness direction of fixed block 1, R2 can be the first direction, and R3 can be the left and right direction.

[0040] In an example, the box body includes a first plate, a second plate, and a third plate, the first plate and the third plate are arranged on both sides of the second plate along the left-right direction of the inner cavity to define three through holes, so that the box body is approximately "U" shaped, the three through holes are respectively front through hole, rear through hole and top through hole, and the panel can be a front plate or a top plate. The riveting die can rivet the front plate and the box body and the top plate and the box body.

[0041] In an example, referring to Figure 1 and Figure 2 , the inner support assembly 2 includes a movable inner support block 21 and a fixed inner support block 22. The movable inner support block 21 is arranged on one side of the fixed block 1 along the left-right direction of the inner cavity, used for abutting or away from the cavity wall along the left-right direction of the inner cavity. The fixed inner support block 22 is arranged on one side of the fixed block 1 along the first direction, used for contacting and abutting with the cavity wall along the first direction of the inner cavity, wherein the first direction is perpendicular to the left-right direction.

[0042] Here, by arranging the fixed inner support block 22 on the fixed block 1 along the first direction, and movably arranging the movable inner support block 21 on one side of the fixed block 1 along the left-right direction, not only can effectively position and support along the first direction and the left-right direction, but also can reduce the collision and scratching between the inner support assembly 2 and the cavity wall along the left-right direction of the inner cavity during the sleeving process, and improve the appearance of the cavity wall of the inner cavity.

[0043] It should be noted that the left and right cavity walls of the inner cavity are used to place the shelf. If the gap between the movable inner support block 21 and the left and right cavity walls is increased in order to reduce scratching, the size of the inner cavity along the left-right direction will be reduced during the subsequent riveting process, so that the shelf cannot be placed. If the movable inner support block 21 is lengthened to reduce the gap between the movable inner support block 21 and the left and right cavity walls of the inner cavity, it will cause the left and right cavity walls to be scratched when the box body is sleeved on the inner positioning device 100. Since the left and right cavity walls are the surfaces that users often observe and belong to the appearance surface, serious scratching will cause defective scrap.

[0044] In an example, the material of the inner support assembly 2 is copper, bakelite or polyethylene.

[0045] That is, the material of the movable inner support block 21 and the fixed inner support block 22 can be copper, or the material of the movable inner support block 21 and the fixed inner support block 22 can be bakelite, or the material of the movable inner support block 21 and the fixed inner support block 22 can be polyethylene. In this way, the damage between the cavity walls supporting the inner cavity can be reduced, and the service life of the box body can be improved.

[0046] In an example, the material of the fixed block 1 is steel.

[0047] In this way, the inner support assembly 2 can provide stable and rigid support when supporting the cavity wall of the inner cavity, and the positioning and support stability are good.

[0048] In an embodiment, the outer surface of the inner support assembly 2 is coated with an elastic buffer coating. That is, the material of the inner support assembly 2 can be a material with high hardness such as steel, and then a certain thickness of elastic buffer coating is coated on the surface to reduce the damage to the cavity wall of the inner cavity.

[0049] In an embodiment, referring to Figures 1 to 4 , the number of the mobile inner support blocks 21 and the fixed inner support blocks 22 is multiple, and the fixed block 1 is provided with the fixed inner support blocks 22 on both sides in the first direction, and the fixed block 1 is movably provided with the mobile inner support blocks 21 on both sides in the left-right direction.

[0050] For example, the number of the mobile inner support blocks 21 and the fixed inner support blocks 22 can be two, two mobile inner support blocks 21 are movably provided on both sides of the fixed block 1 in the left-right direction, and two fixed inner support blocks 22 are provided on both sides of the fixed block 1 in the first direction.

[0051] In this way, by movably providing the mobile inner support blocks 21 on both sides of the fixed block 1 in the left-right direction, not only can the positioning and support of the inner mold plate in the left-right direction be further improved, but also the size of the inner positioning device 100 in the left-right direction can be further reduced when the box is sleeved on the inner positioning device 100, thereby further reducing the risk of scratching the cavity wall of the inner cavity in the left-right direction. By providing the fixed inner support blocks 22 on both sides of the fixed block 1 in the first direction, the positioning and support of the inner mold plate can be further improved.

[0052] In an embodiment, referring to Figures 2 to 4 , one of the mobile inner support blocks 21 and the fixed block 1 is provided with a sliding groove A, and the other is provided with a sliding block B, and the sliding block B and the sliding groove A are in sliding cooperation.

[0053] For example, the mobile inner support block 21 can be provided with the sliding block B, and the fixed block 1 can be provided with the sliding groove A, and the sliding block B and the sliding groove A are in sliding cooperation.

[0054] Here, by providing the sliding block B and the sliding groove A, on the one hand, the sliding groove A can provide a smooth and accurate moving path, and the sliding block B can easily slide in the sliding groove A, so that the whole moving process is more accurate and controllable; on the other hand, the sliding groove A can provide additional support and stability to avoid the sliding block B from shaking or sliding unstably during the moving process, and the moving is stable.

[0055] In an embodiment, referring to Figures 1 to 4 , the inner positioning device 100 comprises a driving member 3, and the mobile inner support block 21 is configured to be telescopic in the left-right direction under the driving of the driving member 3.

[0056] Exemplarily, the driving member 3 comprises a seat body 31 and a driving rod 32, the seat body 31 can be arranged on the other side of the fixed block 1 relative to the inner mold plate along the thickness direction of the fixed block 1 through screws or bolts, etc., one end of the driving rod 32 is arranged in the seat body 31 in an extendable manner, and the other end of the driving rod 32 can be arranged on the sliding block B through screws or bolts, etc., the sliding block B is driven to move in the sliding groove A by the driving rod 32 to drive the movable inner support block 21 to extend and retract along the left-right direction.

[0057] In this way, the movable inner support block 21 is driven to extend and retract along the left-right direction by arranging the driving member 3, and the automation degree and the moving precision are high.

[0058] Exemplarily, in one embodiment, referring to Figure 3 and Figure 4 , the driving member 3 has two driving rods 32, and each driving rod 32 is connected with one sliding block B, so that the two movable inner support blocks 21 can be driven to approach or move away from the cavity wall of the inner cavity or move away from each other and abut against the cavity wall of the inner cavity along the left-right direction by the driving of the driving member 3.

[0059] In one embodiment, the driving member 3 is a finger air cylinder.

[0060] Here, the finger air cylinder is adopted as the driving member 3, on the one hand, the finger air cylinder can accurately control the displacement and position of the movable inner support block 21, so as to realize the support of the movable inner support block 21 to the cavity wall of the inner cavity and improve the positioning precision of the inner mold plate; on the other hand, the structure of the finger air cylinder is relatively compact, so that the occupied space in the box body is relatively small, so as to reduce the scratching caused by the collision with the cavity wall of the inner cavity.

[0061] Exemplarily, in one embodiment, referring to Figure 2 , the fixed block 1 is formed with a positioning groove 1a and a mounting port 1b communicating with the positioning groove 1a, and the inner support assembly 2 is formed with a positioning block 2a, the positioning block 2a can be located in the positioning groove 1a through the mounting port 1b.

[0062] Exemplarily, the side surface of the fixed block 1 along the left-right direction and the first direction of the inner cavity can be formed with the positioning groove 1a and the mounting port 1b communicating with the positioning groove 1a, the two movable inner support blocks 21 and the two fixed inner support blocks 22 can be formed with the positioning block 2a, and the positioning block 2a can be located in the positioning groove 1a through the mounting port 1b, for example, the driving member 3 can drive the movable inner support block 21 to drive the positioning block 2a thereon to enter the positioning groove 1a through the mounting port 1b or to make part of the positioning block 2a to extend out of the positioning groove 1a through the mounting port 1b. In this way, not only the positioning and installation of the inner support assembly 2 can be realized with high installation efficiency, but also the inner support assembly 2 can be stored to a certain extent, so as to further reduce the size of the inner support assembly 2 when it is not supported, and then the damage to the cavity wall of the inner cavity can be reduced.

[0063] In an embodiment, the inner support assembly 2 comprises a fastener, which is arranged through the fixed inner support block 22 and the fixed block 1.

[0064] For example, the fixed inner support block 22 can be formed with a first mounting hole, the fixed block 1 can be formed with a second mounting hole, and the fastener can be a screw or a bolt, etc. The fastener can be arranged through the first mounting hole and the second mounting hole in the first direction to connect the fixed inner support block 22 and the fixed block 1.

[0065] Here, by connecting the fixed inner support block 22 and the fixed block 1 through the fastener, the connection strength between the fixed inner support block 22 and the fixed block 1 can be improved, and the situation of falling off or unstable support during positioning and supporting can be reduced, and the working stability is good.

[0066] For example, in an embodiment, referring to Figure 2 , the sliding block B is formed with a protrusion C, and the positioning block 2a of the movable inner support block 21 is formed with a recess D. The protrusion C can enter the recess D through the slot of the recess D, and then the sliding block B and the movable inner support block 21 can be fixed through a screw or a bolt, etc. In this way, by the cooperation of the protrusion C and the recess D, the installation can be facilitated, and the installation efficiency is high.
