The sliding module has a molding station that slides inward to the vertical molding wall and the vertical surface upper edge of the L-shaped step portion, and slides outward to a stripping position that is misaligned with the vertical molding wall and the vertical surface upper edge of the L-shaped step portion. A stripping spring that drives the sliding module toward the stripping position is provided between the sliding module and the fixed module. Under this structural design, the heat setting mold adopts a sliding module and a fixed module design, and the forming step groove adopts a two-part design. When the sheet blank is formed, it is folded by the sheet edge receiving surface stop, and at the same time, the sliding module presses the sheet blank sideways under the action of the linkage slider and the compression spring. The vertical shaping wall of the sliding module corresponds to the upper edge of the vertical surface of the L-shaped step part, so as to achieve reliable heat setting of the folded edge. At the same time, the compression spring and the stripping spring store energy. After the heat setting of the sheet blank is completed, under the action of the compression spring, the stripping spring and the linkage mechanism, the linkage slider moves and drives the sliding module to quickly bounce to the initial position, and the sheet receiving platform rises to a position corresponding to the position of the sheet edge receiving surface, so that the sheet blank can quickly disengage from the forming step groove of the heat setting module to avoid scalding the product, thereby ensuring reliable processing.

[0007] Preferably, the linkage mechanism includes a T-slot provided on the linkage slider, the T-slot is provided on the side of the linkage slider facing the sliding module, the sliding module has a T-connector protruding on the side facing the linkage slider, the T-connector is inserted into the T-slot, and the T-connector and the T-slot have a relative movable stroke adapted to the compressible movable gap along the sliding direction of the linkage slider.

Under this structural design, when the upper die moves downward, the driving plate on the upper die abuts the driving inclined surface to drive the linkage slider to slide, which has the advantages of simple structure and reliable coordinated action; in addition, the driving plate adopts an inclined surface to cooperate with the driving inclined surface, which can fully ensure that when the lower die moves downward, the linkage slider can slide with a small displacement, thereby making the mold work more reliable.

[0010] Preferably, a floating support spring is provided at the bottom of the sheet receiving platform to drive the sheet receiving platform to rise to the sheet receiving station, and a receiving platform locking mechanism is provided on the lower die seat to lock the sheet receiving platform at the sheet folding and forming station, and the receiving platform locking mechanism cooperates with the locking and unlocking of the sheet receiving platform. Under this structural design, the sheet receiving platform is floatingly supported by the spring, the floating support spring provides the driving force for the sheet receiving platform to rise, and the receiving platform locking mechanism realizes the retention of the sheet receiving platform at the sheet folding and forming station, so that the receiving platform can be unlocked and raised at the sheet folding and forming station after the upper die rises to a specific position.

[0011] The locking mechanism of the receiving platform includes a locking block slidably arranged on the lower mold base and a locking step opening arranged on the side edge of the sheet material receiving platform, the locking block is arranged on the side of the sheet material receiving platform, and the locking block has a locking head end that can slide into and out of the locking step opening toward one end of the sheet material receiving platform, and the locking block is matched with a locking spring that drives the locking head end to slide into the locking step opening, and an unlocking operation hole is provided on the locking block, and the locking block has a locking position where the locking head end is placed in the locking step opening and an unlocking position where the locking head end exits the locking step opening. The sheet material receiving platform is located below the locking step opening and is provided with a physical part for the locking head end to abut against to form a locking block to compress the locking spring to store energy. The upper mold base is provided with an unlocking hook, and the unlocking hook is provided with an unlocking convex head that pushes and cooperates with the wall of the unlocking operation hole when the locking block is in the unlocking position. The unlocking operation hole allows the unlocking convex head of the unlocking hook to pass over, and when the locking block is in the locked position, the unlocking convex head of the unlocking hook pushes and cooperates with the wall of the unlocking operation hole to form a toggle lock block to slide to the locking head end and slide out of the locking step opening. Under this structural design, during the travel of the sheet receiving platform from the sheet receiving station to the sheet folding and forming station, the solid part contacts the stopper against the locking head end, causing the locking spring to be in a compressed energy storage state, so that after the sheet receiving platform reaches the sheet folding and forming station, the locking block slides under the action of the locking spring, and the locking head end enters the locking step mouth, thereby locking the sheet receiving platform on the sheet folding and forming station. During the unlocking operation, the upper mold moves upward, and the unlocking protrusion of the unlocking hook enters the unlocking operation hole and pushes against the wall of the unlocking operation hole to push the locking block to the unlocking position.

[0012] Preferably, the shaping convex module is floatingly supported on the upper die seat, and a convex module support spring is provided between the upper die seat and the shaping convex module.

In this specific embodiment, a pair of hemming heat setting components are provided on the left and right sides of the sheet receiving platform 22, and the two groups of heat setting components are relatively arranged on the left and right sides of the sheet receiving platform. Of course, one group of hemming heat setting components or three groups or four groups can be designed according to needs. The sheet receiving platform 22 is floatingly supported on the lower die seat 21 and can be raised and lowered. The hemming heat setting component comprises a heat setting module 23, and the heat setting module 23 is provided with a pair of heat setting components. The heating element 23-1 is heated by the shaping module 23, and a shaping step groove Ⅰ and a sheet edge receiving surface Ⅱ located above the shaping step groove Ⅰ are provided on one side of the heat shaping module 23 corresponding to the sheet receiving platform 22. The sheet receiving platform 22 has a sheet receiving station that rises to a position corresponding to the sheet edge receiving surface Ⅱ and a sheet folding shaping station that descends to a position corresponding to the bottom of the shaping step groove Ⅰ. The upper mold 1 includes an upper mold base 11 and a shaping convex module 12 installed on the upper mold base 11. The shaping convex module 12 has a pressing surface 121 that can be pressed on the sheet receiving platform 22 to clamp the sheet. The side of the pressing surface 121 of the shaping convex module 12 is provided with a shaping step Ⅲ that is compatible with the shaping step groove Ⅰ.

[0027] The heat setting module 23 includes a fixed module 231 and a sliding module 232. The sliding module 232 is arranged on the lower mold base 21 along the side of the sheet receiving platform 22 and slides linearly. The fixed module 231 is arranged between the sliding module 232 and the sheet receiving platform 22. The fixed module 231 is provided with an L-shaped step portion 2311. The sliding module 232 is provided with a vertical shaping wall 2321 that can be connected with the upper edge of the vertical surface of the L-shaped step portion 2311. The vertical shaping wall 2321 and the L-shaped step portion 2311 surround the forming step groove I. The sheet edge receiving surface II is arranged above the vertical shaping wall 2321 of the sliding module 232. The sliding module 232 is linked to a linkage slider corresponding to the sliding direction of the sliding module 232 and away from the side of the sheet receiving platform 22. 24, the linkage slider 24 is slidably arranged on the lower die base 21, a compression spring 25 is arranged between the linkage slider 24 and the sliding module 232, a compressible activity gap IV is provided between the linkage slider 24 and the sliding module 232, a linkage mechanism is arranged between the linkage slider 24 and the sliding module 232, which maintains the compressible activity gap IV between the linkage slider 24 and the sliding module 232 under the action of the compression spring 25 and has a relative activity stroke V adapted to the compressible activity gap IV, the activity stroke inherent in the linkage mechanism can adapt to the relative activity (compressible activity gap IV) between the linkage slider 24 and the sliding module 232, and the sliding module 232 has a molding station (such as a molding station) that slides inward to the vertical molding wall 2321 and the vertical surface upper edge of the L-shaped step portion 2311 Figure 2 , Fig. 9 As shown) and sliding outward to the stripping position where the vertical shaping wall 2321 and the vertical upper edge of the L-shaped step portion 2311 are misaligned (as shown Figure 6 , Figure 7As shown in the figure, a stripping spring 233 is provided between the sliding module 232 and the fixed module 231 to drive the sliding module 232 to the stripping position. The heat setting mold adopts the design of sliding module and fixed module, and the forming step groove adopts a two-part design. When the sheet blank is formed, it is stopped and folded by the receiving surface of the edge of the sheet. At the same time, the sliding module presses the sheet blank folding edge sideways under the action of the linkage slider and the compression spring. The vertical shaping wall of the sliding module is correspondingly connected with the upper edge of the vertical surface of the L-shaped step portion, so as to achieve the lateral push of the folded edge and achieve reliable heat setting. At the same time, the compression spring and the stripping spring store energy. After the heat setting of the sheet blank is completed, under the action of the compression spring, the stripping spring and the linkage mechanism, the linkage slider moves and drives the sliding module to quickly pop open to the initial position. Then the sheet receiving platform rises to the position corresponding to the position of the receiving surface of the edge of the sheet, so that the sheet blank is quickly separated from the forming step groove of the heat setting module to avoid scalding the product, thereby ensuring reliable processing. Under the above structure, it can be ensured that the folding edge is processed and formed as a decorative sheet with the free end offset inward, that is, the vertical shaping wall 2321 is an inclined setting extending from the lower end to the upper end obliquely to one side (inner side) of the sheet receiving platform 22. Of course, as a feasible solution of the present invention, the heat setting module can be fixed on the lower die seat as a whole, or a sliding module design with a complete molded step groove can be adopted, and a linkage slider, compression spring, and stripping spring design can be used. However, under the design of the split sliding module and the fixed module, the split processing of the molded step groove is realized, which ensures the advantage of reliable folding edge processing of the decorative sheet.

[0028] The linkage mechanism includes a T-slot 24-1 arranged on the linkage slider 24, the T-slot 24-1 is arranged on the side of the linkage slider 24 facing the sliding module 232, and the sliding module 232 has a T-connector 232-1 protruding on the side of the linkage slider 24, the T-connector 232-1 is inserted into the T-slot 24-1, and the T-connector 232-1 and the T-slot 24-1 have a relative movable stroke V adapted to the compressible movable gap IV along the sliding direction of the linkage slider 24. The linkage structure is simple in structure, convenient in processing, and reliable in linkage connection. A sliding guide groove is arranged on the lower die seat, one end of the sliding guide groove leads to the fixed module, and a limiter for limiting the linkage slider is arranged at the outer port of the sliding guide groove, which is a bolt in the figure. The linkage slider and the sliding module are assembled in the same sliding guide groove, wherein preferably, the T-slot is arranged to pass through the linkage slider from top to bottom, so that the T-connector of the sliding module is conveniently installed in the T-slot.

[0029] In order to make the upper mold and the lower mold work better together, the outer side of the linkage slider 24 is provided with a driving inclined surface 241 that is inclined outward from top to bottom, and the upper mold seat 11 is provided with a driving plate 13 that extends downward and is used to contact the driving inclined surface 241 to push the linkage slider 24. In this way, when the upper mold is lifted or lowered, the driving plate presses against the driving inclined surface to drive the linkage slider, thereby ensuring that the lower mold is lifted or lowered to a specified position and driving the linkage slider, and ensuring the reliable coordination of the upper mold and the lower mold; and the mating surface 131 on the driving plate 13 that contacts the driving inclined surface 241 is a bevel. The driving plate adopts a bevel to cooperate with the driving bevel, which can fully ensure that the linkage slider can slide with a small displacement when the lower mold is in a downward stroke, thereby making the mold work more reliable.

[0030] The bottom of the sheet receiving platform 22 is provided with a floating support spring 22-1 that drives the sheet receiving platform 22 to rise to the sheet receiving station, and the lower die seat 21 is provided with a receiving platform locking mechanism that locks the sheet receiving platform 22 on the sheet folding molding station, and the receiving platform locking mechanism cooperates with the sheet receiving platform 22 to lock and unlock. The sheet receiving platform is supported by spring floating, and the floating support spring provides the driving force for the sheet receiving platform to rise. The receiving platform locking mechanism realizes the retention of the sheet receiving platform on the sheet folding molding station, so that the receiving platform can be unlocked and raised at the sheet folding molding station after the upper die rises to a specific position. For example, after the sliding module is reset to the initial position, the sheet receiving platform is unlocked and raised at the sheet folding molding station, so that the decorative sheet is lifted and demolded after molding. Of course, the sheet receiving platform can also adopt an active driving mechanism to realize the floating support of the sheet receiving platform, such as a cylinder, but the design of the floating support spring and the receiving platform locking mechanism has the advantages of simple structure and reliable operation.

[0031] The receiving platform locking mechanism includes a locking block 261 slidably arranged on the lower die seat 21 and a locking step opening 221 arranged on the side edge of the sheet receiving platform 22. The locking block 261 is arranged on the side of the sheet receiving platform 22. The locking block 261 has a locking head end 2611 that can slide into and out of the locking step opening 221 at one end of the sheet receiving platform 22. The locking block 261 is equipped with a locking spring 262 that drives the locking head end 2611 to slide into the locking step opening 221. The locking block 261 is provided with an unlocking operation hole 2612. The locking block 261 has a locking position in which the locking head end 2611 is placed in the locking step opening 221 and an unlocking position in which the locking head end 2611 exits the locking step opening 221. The sheet receiving platform 22 is located below the locking step mouth 221 and is provided with a solid part 222 for the locking head end 2611 to contact to form the locking block 261 to compress the locking spring 262 to store energy. The upper mold base 11 is provided with an unlocking hook 14, and the unlocking hook 14 is provided with an unlocking protrusion 141 that is pushed and matched with the wall of the unlocking operation hole 2612. When the locking block 261 is in the unlocking position, the unlocking operation hole 2612 is allowed to pass through the unlocking protrusion 141 of the unlocking hook 14. When the locking block 261 is in the locking position, the unlocking protrusion 141 of the unlocking hook 14 is pushed and matched with the wall of the unlocking operation hole 2612 to form a locking block 261 that slides to the locking head end 2611 and slides out of the locking step mouth 221. During the travel of the sheet receiving platform from the sheet receiving station to the sheet folding and forming station, the solid part abuts against the locking head end to stop the locking spring so that the locking spring is in a compressed energy storage state, so that after the sheet receiving platform reaches the sheet folding and forming station, the locking block slides under the action of the locking spring, and the locking head end enters the locking step, thereby locking the sheet receiving platform on the sheet folding and forming station. During the unlocking operation, the upper mold moves upward, and the unlocking convex head of the unlocking hook enters the unlocking operation hole and pushes against the unlocking operation hole wall to push the locking block to the unlocking position. A guiding inclined surface is provided on the unlocking convex head, so that the unlocking convex head can smoothly push the locking block.

[0032] The shaping convex module 12 is floatingly supported on the upper die seat 11, and a convex module support spring 12-1 is provided between the upper die seat 11 and the shaping convex module 12. The shaping convex module 12 is more gently in contact with and separated from the sheet receiving platform, and has a better clamping effect on the sheet.

[0033] In order to improve the reliability of the mold operation, water cooling channels are set at specific positions of the upper mold and the lower mold to protect the sheet material, such as an upper mold water cooling channel is set in the upper mold base 11, or / and a punch water cooling channel 122 is set on the shaping convex module 12, and the upper mold water cooling channel and the punch water cooling channel can be connected in sequence, or / and a lower mold water cooling channel 211 is set in the lower mold base 21, or / and a receiving platform water cooling channel 223 is set in the sheet receiving platform 22, and the receiving platform water cooling channel is connected in sequence with the lower mold water cooling channel. According to common knowledge in this field, the connection of the channels can be achieved by a connecting pipe (not shown in the figure) to ensure that the mold works stably and reliably and reduce the impact on the sheet material. The cooling medium can be water, and of course it can also be cooling oil.

[0034] The working principle of the decorative sheet folding forming mold is as follows: the heat setting module is heated to the temperature required for heat setting by the heating element. The heating element is a conventional component, such as an electric heating rod. The sheet receiving platform is in the sheet receiving station. The sheet blank is placed on the sheet receiving platform, and the edge of the sheet blank is placed above the sheet edge receiving surface. The upper mold descends, and the shaping convex module presses on the sheet receiving platform to clamp the sheet blank downward. The side of the sheet blank is stopped by the sheet edge receiving surface until the sheet receiving platform enters the sheet folding forming station. The edge of the sheet blank is heat-set through the forming step groove and the shaping step of the shaping convex module. The upper mold ascends to disengage the lower mold, and the sheet blank is heat-set to form a decorative sheet with folded edges.
