[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 3 As shown, a large-scale plate-shaped automobile component stamping and forming integrated equipment of the present invention comprises a die set, wherein the die set is composed of a male die unit as an upper die and a female die unit as a lower die; The punch unit comprises a lower die 1, a plurality of first die rods 2 are vertically slidably inserted in the middle of the lower die 1, and the bottom surfaces of the first die rods 2 and the bottom surface of the lower die 1 form a complete punch; The die unit includes an upper core die 3 and a plurality of side die dies 4 surrounding the upper core die 3. The upper core die 3 is separated from the side die dies 4. A plurality of second die rods 5 are vertically slidably inserted through the middle of the upper core die 3. The top of the upper core die 3, the inner side walls of the plurality of side die dies 4 and the tops of the plurality of second die rods 5 form a complete die.

[0020] Specifically, in the initial position, the bottom of the first die rod 2 is located below the lower die 1, the top of the second die rod 5 is located above the side die 4, and the position of the first die rod 2 corresponds to the position of the second die rod 5. When stamping work is required, the plate is placed on the top of the multiple second die rods 5, and the lower die 1 and the first die rod 2 are pushed to move downward. The first die rod 2 first contacts the upper surface of the plate. At this time, the second die rod 5 pushes the first die rod 2 to stop moving through the plate, and the lower die 1 continues to move and contact the plate. The first die rod 2 slides on the lower die 1, and the lower die 1 pushes the plate to move downward. The plate pushes the second die rod 5 to move downward, and the second die rod 5 slides on the upper core die 3. The plate can be first extruded and positioned by the first die rod 2. At this time, the plate is In a stationary state, the sheet can be squeezed and fixed by the lower pressing die 1 and the second die rod 5. At this time, the sheet is in a moving state, so as to avoid the sheet from being offset and affecting the processing accuracy when moving, and push the multiple side molds 4 to move toward the upper supporting core mold 3. When the top of the second die rod 5 is flush with the top of the side mold 4, the upper supporting core mold 3 and the multiple side molds 4 are combined, and the bottom outer edge of the sheet contacts the top of the side mold 4. The lower pressing die 1 continues to move downward and presses the sheet between the upper supporting core mold 3 and the multiple side molds 4. When the top of the second die rod 5 is flush with the top of the upper supporting core mold 3, the upper supporting core mold 3, the side mold 4 and the second die rod 5 are combined into a complete concave mold. The first die rod 2 presses the sheet into the complete concave mold and performs stamping and forming processing, thereby realizing the forming processing of the sheet.

[0021] When the sheet processing is completed, the lower die 1 and the first die rod 2 move upward and return to their initial positions, and the multiple side dies 4 move away from the upper core die 3 synchronously, so that the multiple side dies 4 stop blocking the stamped parts and push the second die rod 5 to move upward. The second die rod 5 pushes the parts on the upper core die 3 to move upward, so that the parts are separated from the die unit, realizing the immediate and rapid demolding of the parts.

[0022] In actual use, the sheet is generally stuck in the die due to the rebound tension inside it after the sheet is formed. When the sheet is stuck on the lower die 1 due to accidental phenomena, the sheet can be pushed away from the lower die 1 by the first die rod 2 when the lower die 1 moves upward, so that the sheet stays on the top of the multiple second die rods 5 to avoid the sheet being stuck on the lower die 1.

[0023] It can be seen that by using the splicing combination mold method to stamp the sheet metal, the immediate and rapid demoulding of the parts after stamping can be achieved, the demoulding method can be effectively simplified, the time occupied by demoulding can be shortened, and the processing efficiency of parts can be improved. At the same time, the difficulty of demoulding can be effectively reduced, manpower can be saved, and damage to the mold during manual demoulding can be avoided.

[0024] like Figure 4 As shown, as a preferred embodiment of the above embodiment, a pushing structure is provided at the bottom of the upper supporting core mold 3, and the pushing structure can push the upper supporting core mold 3 to move upward; A slide groove is provided at the bottom of the side mold 4, and two first sliders 6 are slidably arranged in the slide groove. A support plate 7 is tiltably and rotatably arranged on the first slider 6. The outer end of the support plate 7 is rotatably installed at the bottom of the upper core mold 3, and the tilt directions of the two support plates 7 on the side mold 4 are opposite.

[0025] Specifically, when the lower die 1 pushes the sheet material to move downward, the pushing structure can push the upper core mold 3 to move upward, so that the male die unit and the female die unit can simultaneously perform active extrusion molding processing on the upper and lower surfaces of the sheet material. When the upper core mold 3 moves, the upper core mold 3 drives the side mold 4 to move synchronously through the first slider 6 and the support plate 7, so as to facilitate keeping the upper core mold 3 and the side mold 4 on the same plane. When the side mold 4 moves relative to the upper core mold 3, the side mold 4 pulls the support plate 7 to tilt through the first slider 6, and the first slider 6 can slide in the slide groove.

[0026] like Figures 4 to 5 As shown, as a preferred embodiment of the above embodiment, the pushing structure includes a cross push plate 8 installed at the bottom of the upper core mold 3, a first empty groove is opened on the side wall of the cross push plate 8 and the side wall of the second mold rod 5, a tooth is arranged in the first empty groove, a first gear 9 is arranged between the cross push plate 8 and the second mold rod 5, and the first gear 9 is respectively meshed with the teeth on the second mold rod 5 and the teeth on the cross push plate 8; It also includes a base 10, which is located below the upper core mold 3, the bottom of the second mold rod 5 is slidably inserted into the base 10, the bottom of the cross push plate 8 is slidably inserted into the base 10, and the first gear 9 is rotatably installed on the base 10.

[0027] Specifically, when the second mold rod 5 moves downward, the second mold rod 5 slides on the base 10, and the second mold rod 5 pushes the cross push plate 8 to move upward through the first gear 9, and the cross push plate 8 pushes the upper core mold 3 to move upward, thereby realizing the synchronous movement of the male mold unit and the female mold unit.

[0028] By arranging the teeth in the first empty groove, it can be avoided that the upper teeth of the second mold rod 5 and the cross push plate 8 affect the upper core mold 3 or the base 10 when they move.

[0029] like Figure 6As shown, as a preferred embodiment of the above, a vertical plate 11 is provided on the outer side of each of the side molds 4, a second slider 12 is vertically slidably provided on the vertical plate 11, two guide plates 13 are obliquely and rotatably provided on the outer side wall of the second slider 12, the two guide plates 13 are parallel, the outer ends of the guide plates 13 are rotatably mounted on the outer side wall of the side mold 4, a first leaf spring 14 is provided on the guide plate 13, the first leaf spring 14 is connected to the second slider 12, a second leaf spring 15 is provided on the top of the second slider 12, and the outer end of the second leaf spring 15 is fixed on the vertical plate 11; An arched plate 16 is provided on the vertical plate 11, and the end of the arched plate 16 slides horizontally through the vertical plate 11. The upper side of the side wall of the arched plate 16 facing the upper supporting core mold 3 is set as a vertical surface, and the lower side is set as an arc surface. A sliding column 18 is provided on the side wall of a guide plate 13 on the second sliding block 12, and the outer wall of the sliding column 18 is in sliding contact with the end of the arched plate 16; A first cylinder 17 is disposed between the vertical plate 11 and the arch plate 16 .

[0030] Specifically, the elastic coefficient of the first leaf spring 14 is greater than the elastic coefficient of the second leaf spring 15. In the initial state, the first cylinder 17 fixes the arch plate 16 on the vertical plate 11. When the upper supporting core mold 3 moves upward, the upper supporting core mold 3 drives the side mold 4 to move synchronously through the first slider 6 and the supporting plate 7. At this time, the side mold 4 pushes the slide column 18 to slide on the end of the arch plate 16 through its upper guide plate 13. The slide column 18 first slides on the arc surface of the arch plate 16. At this time, the position of the second slider 12 is fixed, and the slide column 18 drives the guide plate 13 to flip upward. The two guide plates 13 on the second slider 12 move synchronously, so that the side mold 4 moves upward in a translational and tilted manner. While the side mold 4 moves upward synchronously with the upper supporting core mold 3, the side mold 4 gradually approaches the upper supporting core mold 3. When When the slide column 18 slides on the vertical surface of the arch plate 16, the slide column 18 moves to the farthest distance from the second slider 12 in the horizontal direction, the guide plate 13 rotates to a horizontal state, the side mold 4 and the upper supporting core mold 3 are in a docking combination state, the top of the second mold rod 5 is flush with the top of the side mold 4, and when the lower die 1 presses the sheet into the die, the second mold rod 5 continues to move downward, the upper supporting core mold 3 and the side mold 4 continue to move upward. At this time, the upper supporting core mold 3 and the side mold 4 are in a combined state, so that the male mold unit and the female mold unit simultaneously extrude and form the sheet. At this time, the side mold 4 drives the slide column 18 to slide on the vertical surface of the arch plate 16, and the guide plate 13 drives the second slider 12 to slide vertically upward, and the second slider 12 pushes the second leaf spring 15 to undergo elastic deformation.

[0031] When the sheet shaping processing is completed, the first cylinder 17 pushes the arch plate 16 to slide outward on the vertical plate 11, and the arch plate 16 gradually moves away from the upper supporting core mold 3, pushing the lower pressure mold 1 and the first mold rod 2 to gradually move upward. Since the elastic coefficient of the first leaf spring 14 is greater than the elastic coefficient of the second leaf spring 15, the first leaf spring 14 first pulls the guide plate 13 to tilt downward and rotate, and the guide plate 13 pulls the side mold 4 to tilt away from the upper supporting core mold 3, and multiple side molds 4 are synchronously tilted away from the upper supporting core mold 3, so that the side mold 4 is first demolded. At this time, the side mold 4 drives the upper supporting core mold 3 to move downward synchronously, and the second mold rod 5 moves upward in the opposite direction, and the second mold rod 5 pushes the parts to separate from the upper supporting core mold 3, so that the upper supporting core mold 3 is demolded synchronously. When the guide plate 13 gradually returns to its initial state, the second leaf spring 15 pushes the second slider 12 to move downward, so that the upper supporting core mold 3 and the side mold 4 gradually move to the initial position, and the parts are separated from the concave mold unit.

[0032] By adopting the structure of the first leaf spring 14, the second leaf spring 15, the bow plate 16 and the sliding column 18, during the stamping operation, the die unit is first spliced, and then moves upward to perform stamping and forming processing on the plate. When the parts are processed, the die unit is first disassembled, and the side mold 4 and the upper supporting core mold 3 are separated, thereby realizing the movement mode of first demolding the upper supporting core mold 3 and the side mold 4 and then moving downward to the initial position.

[0033] The movement process of the die unit is unpowered, and its power source is the downward pressure of the punch unit. Therefore, it can effectively save the number of power settings, simplify the equipment structure, reduce costs, reduce the assembly space and wiring harness layout space, and simplify the equipment operation method.

[0034] like Figure 7 As shown, as a preferred embodiment of the above embodiment, a second slot is opened on the outer wall of the second mold rod 5, a flip plate 19 is rotatably arranged in the second slot, a second cylinder 20 is tilted and rotatably arranged at the bottom of the flip plate 19, the fixed end of the second cylinder 20 is rotatably installed on the inner wall of the second slot, and a positioning slot plate 21 is fixed on the top of the flip plate 19.

[0035] Specifically, in the initial state, the second cylinder 20 pushes the flip plate 19 to rotate to a horizontal state, and the second cylinder 20 simultaneously pushes the positioning slot plate 21 to a horizontal state, and places the plate in the multiple positioning slot plates 21 on the multiple second mold rods 5. The plate can be positioned by the multiple positioning slot plates 21. When the bottom of the first mold rod 2 contacts the plate and squeezes and fixes the plate, the second cylinder 20 pulls the flip plate 19 to rotate back to the second empty slot. At this time, the flip plate 19, the second cylinder 20 and the positioning slot plate 21 are all received in the second empty slot, thereby avoiding the flip plate 19, the second cylinder 20 and the positioning slot plate 21 from colliding and damaging the upper core mold 3 when the second mold rod 5 moves.

[0036] like Figure 2 As shown, as a preferred embodiment of the above embodiment, a limiting plate 22 is provided on the top of the side mold 4 , and the outer end of the limiting plate 22 contacts the side wall of a guide plate 13 on the second sliding block 12 .

[0037] Specifically, by setting the limit plate 22, the inclination angle of the guide plate 13 can be conveniently positioned and limited, thereby limiting the position of the side mold 4 and the upper core mold 3, and conveniently limiting the inclination angle of the support plate 7 to avoid the side mold 4 moving a large distance, the support plate 7 rotating from the inclined state to the horizontal straight state, resulting in the first slider 6 and the inner wall of the slide groove getting stuck when the side mold 4 moves, thereby ensuring the normal operation of the equipment.

[0038] like Figure 8 As shown, as a preferred embodiment of the above embodiment, the number of the first mold rods 2 and the number of the second mold rods 5 are both four, two mounting plates 23 are arranged on the top of the lower die 1, two rotating shafts 24 are rotatably arranged between the two mounting plates 23, two second gears 25 are fixed on the rotating shafts 24, the second gears 25 on the two rotating shafts 24 are meshed and connected with each other, and a third leaf spring 26 is connected between the two rotating shafts 24; A third slot is formed on the outer wall of the first mold rod 2. The third slot is provided with teeth. The second gear 25 is meshed and connected with the teeth in the third slot.

[0039] Specifically, the four first mold rods 2 and the four second mold rods 5 are symmetrically distributed, and the two ends of the third leaf spring 26 can generate elastic thrust on the two rotating shafts 24. Since the second gears 25 on the two rotating shafts 24 are meshed and connected, the second gears 25 are meshed and connected with the teeth on the first mold rods 2, and two second gears 25 are provided on one rotating shaft 24, the four second gears 25 maintain a synchronous movement state, which facilitates the synchronous movement of the four first mold rods 2.

[0040] like Figure 1 As shown, as a preferred embodiment of the above embodiment, it also includes a bottom plate 27, the bottom of the base 10 is fixed on the bottom plate 27, a support sleeve 28 is provided on the bottom plate 27, and the bottom of the vertical plate 11 is fixed on the support sleeve 28; The outer side of the mold group is buckled with a U-shaped outer plate 29, which is fixed on the bottom plate 27. A cylinder 30 is arranged on the top of the U-shaped outer plate 29, and a U-shaped frame 31 is arranged at the bottom movable end of the cylinder 30, which is connected to the lower die 1.

[0041] Specifically, the oil cylinder 30 can push the lower die 1 to move up and down through the U-shaped frame 31, so as to perform stamping and forming processing on the plate, and the bottom plate 27 and the supporting sleeve plate 28 can support the base 10 and the vertical plate 11.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
