Description

Technical Field

[0001] This utility model relates to the field of mold design, and in particular to a deep drawing mold for automotive metal parts. Background Technology

[0002] The typical structure of steel plate stretching molds consists of an upper mold plate and a lower mold plate. The cavities and cores on the upper and lower mold plates close together to press the sheet metal into the corresponding shape. The outer periphery of the sheet metal is pressed between the cavity and the core for stretching. After processing, ejector pins are used to eject the workpiece.

[0003] A rolling deep drawing die for thick metal rectangular parts has been disclosed on the market (Announcement No.: CN204672822U, Announcement Date: 2015.09.30). During the entire stamping process, the part is always in contact with the roller. During operation, the roller rolls in the corresponding die insert and rolls the surface of the part. The surface of the part after rolling is flat and smooth. The relative rolling between the roller and the part results in very small rolling friction, so the part is free from scratches and cracks, which improves product quality and solves the problems of surface scratches, necking and cracking in deep drawing of thick plates.

[0004] However, existing deep drawing dies only have the function of deep drawing. In many existing metal parts products, it is necessary to punch holes in the sheet metal before deep drawing. Since existing deep drawing dies do not have the function of punching, an additional set of dies is required, which results in very high costs. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A deep drawing die for automotive metal parts includes an upper die and a lower die. The lower side of the upper die is formed with one or more stamping cavities, and the lower die is formed with one or more stamping holes. The stamping cavities are arranged above the stamping holes in a one-to-one correspondence.

[0007] Two support plates are fixedly installed on the bottom side of the lower mold, and a base plate is fixedly installed on the bottom side of the two support plates. A shift plate is slidably installed between the two support plates. One or more punching holes are formed on the shift plate. The punching holes and the stamping holes are arranged corresponding to each other. After the shift plate moves to the right and is misaligned, it blocks the lower end of the stamping hole.

[0008] A punching plate or a deep drawing positioning plate is installed on the lower side of the upper die. One or more clearance holes are formed on both the punching plate and the deep drawing positioning plate. The stamping cavities are installed in the clearance holes with a one-to-one clearance fit.

[0009] Furthermore: four clamping springs are installed between the punching plate and the upper die, and several countersunk holes are formed on the upper side of the upper die. Locking bolts are installed in the countersunk holes with clearance fit. The lower end of the locking bolt passes through the upper die and is locked on the punching plate. The nut of the locking bolt is installed in the countersunk hole with lifting and sliding fit.

[0010] Furthermore: the four ends of the upper side of the punching plate are each formed with a first spring groove, and the four ends of the lower side of the upper die are each formed with a second spring groove, and the clamping springs are installed in a corresponding manner between the first spring groove and the second spring groove.

[0011] Furthermore: a side plate is formed on the right side of the upper side of the base plate, the right side of the lower mold and the side plate are separated from each other, the right end of the support plate abuts against the side plate, and a toggle edge is formed on the right side of the upper side of the shifting plate, with the toggle edge being fitted between the right side of the lower mold and the side plate with clearance.

[0012] Furthermore: when the actuating edge abuts against the right side of the lower die, the punching hole and the stamping hole are aligned with each other; when the actuating edge abuts against the side plate, the punching plate blocks the lower end of the stamping hole.

[0013] Furthermore, an electromagnetic lock is embedded in the actuating edge, and the actuating edge is locked to the right side or side plate of the lower mold by the magnetic attraction of the electromagnetic lock.

[0014] Furthermore, the bottom plate has one or more scrap holes formed on its lower side, and the punching holes and scrap holes are interconnected.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. When installing the punching plate, move the shifting plate in the lower mold to the appropriate position so that the punching hole and the stamping hole are aligned. Then fix the shifting plate and close the mold. When the mold is closed, the stamping cavity will be inserted into the stamping hole. Since the punching plate will press on the lower mold before the mold is closed, it can press the sheet metal before the mold is closed. When the stamping cavity is inserted into the stamping hole, it can achieve the punching effect. The waste material after punching can be recycled through the punching hole, thus realizing the function of the punching mold.

[0017] 2. When installing the deep drawing positioning plate, move the shift plate in the lower mold to the other side so that the punching hole and the stamping hole are staggered. Then, the shift plate blocks the lower end of the stamping hole. Then fix the shift plate to perform the mold closing action. During the mold closing process, since the edge of the sheet is not pressed, the sheet will deform at the position of the stamping cavity, thereby realizing the deep drawing action and having the function of a deep drawing mold.

[0018] This invention enables the integrated design of punching and deep drawing dies. The function of switching dies is achieved by replacing the punching plate and the deep drawing positioning plate. After switching to the drawing die, the punching hole and the punching hole can be aligned by moving the displacement plate, which facilitates the recycling of waste material. After switching to the deep drawing die, the lower end of the punching hole can be blocked by moving the displacement plate to ensure the deep drawing effect of the corresponding position of the sheet metal.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] 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.

[0035] like Figure 1-8As shown, a deep drawing die for automotive metal parts according to this utility model includes an upper die 1 and a lower die 2. One or more stamping cavities 3 are formed on the lower side of the upper die 1, and one or more stamping holes 4 are formed on the lower die 2. The stamping cavities 3 are arranged one-to-one above the stamping holes 4.

[0036] Two support plates 5 are fixedly installed on the bottom side of the lower mold 2, and a base plate 6 is fixedly installed on the bottom side of the two support plates 5. A shift plate 7 is slidably installed between the two support plates 5. One or more punching holes 8 are formed on the shift plate 7. The punching holes 8 and the stamping holes 4 are arranged corresponding to each other. After the shift plate 7 moves to the right and is misaligned, it blocks the lower end of the stamping hole 4.

[0037] The lower side of the upper mold 1 is equipped with a punching plate 9 or a deep drawing positioning plate 10. Both the punching plate 9 and the deep drawing positioning plate 10 are formed with one or more clearance holes 11. The stamping cavity 3 is installed in the clearance hole 11 with a corresponding clearance fit.

[0038] The principle is as follows: A punching plate 9 or a deep-drawing positioning plate 10 can be selectively installed on the lower side of the upper die 1. When installing the punching plate 9, the shifting plate 7 inside the lower die 2 is moved to a suitable position, aligning the punching hole 8 with the stamping hole 4. The shifting plate 7 is then fixed in place for die closing. During die closing, the stamping cavity 3 inserts into the stamping hole 4. Because the punching plate 9 presses against the lower die 2 before die closing, it can clamp the sheet metal before the die closes. When the stamping cavity 3 inserts into the stamping hole 4, it achieves the punching effect. The punched material... Waste material can be recycled through the punching hole 8, realizing the function of the punching die; when installing the deep drawing positioning plate 9, the shifting plate 7 in the lower die 2 is moved to the other side, so that the punching hole 8 and the stamping hole 4 are staggered, and then the shifting plate 7 blocks the lower end of the stamping hole 4. Then the shifting plate 7 is fixed to perform the mold closing action. During the mold closing process, since the edge of the sheet is not pressed, the sheet will deform at the position of the stamping cavity 3, thereby realizing the deep drawing action and realizing the function of the deep drawing die.

[0039] Furthermore: four clamping springs 12 are installed between the punching plate 9 and the upper die 1. The upper side of the upper die 1 is formed with several countersunk holes 13. Locking bolts 14 are installed in the countersunk holes 13 with clearance fit. The lower end of the locking bolts 14 passes through the upper die 1 and is locked on the punching plate 9. The nuts of the locking bolts 14 are installed in the countersunk holes 13 with lifting and sliding fit. During the die closing process, the punching plate 9 can be pressed on the lower die 2 by the clamping springs 12, which can press down the edge of the sheet material to be punched. At this time, the die continues to close, allowing the stamping cavity 3 to be inserted into the stamping hole 4. Since the edge of the sheet material will not be displaced, the punching action can be performed at the stamping hole 4, realizing the technical effect of punching the punching die.

[0040] Furthermore: the four ends of the upper side of the punching plate 9 are all formed with first spring grooves 15, and the four ends of the lower side of the upper die 1 are all formed with second spring grooves 16. The compression springs 12 are installed in a one-to-one correspondence between the first spring grooves 15 and the second spring grooves 16, which can ensure the stable installation of the compression springs 12.

[0041] Furthermore: a side plate 17 is formed on the right side of the upper side of the base plate 6. The right side of the lower mold 2 and the side plate 17 are separated from each other. The right end of the support plate 5 abuts against the side plate 17. A toggle edge 18 is formed on the right side of the upper side of the shift plate 7. The toggle edge 18 is set between the right side of the lower mold 2 and the side plate 17 with clearance fit. The shift plate 7 can be moved by the toggle edge 18 to allow the punching hole 4 to quickly align with the punching hole 8 to achieve rapid punching. Alternatively, the shift plate 7 can be blocked by the toggle edge 18 to achieve the effect of a deep drawing mold.

[0042] Furthermore: when the actuating edge 18 abuts against the right side of the lower die 2, the punching hole 8 and the stamping hole 4 are aligned with each other; when the actuating edge 18 abuts against the side plate 17, the punching plate 9 blocks the lower end of the stamping hole 4; thus achieving rapid alignment of the punching hole 8 and the stamping hole 4, or allowing the punching plate 9 to quickly block the stamping hole 4, thereby achieving rapid switching of the working mode of the die.

[0043] Furthermore, an electromagnetic lock 19 is embedded in the actuating edge 18. The actuating edge 18 is magnetically locked to the right side of the lower mold 2 or the side plate 17 by the electromagnetic lock 19. The electromagnetic lock 19 can be used for magnetic locking. When the magnetic locking is performed, the shift plate 7 will no longer move. At this time, the mold closing action is performed to ensure the stability of the mold during operation.

[0044] Furthermore, the bottom plate 6 has one or more waste holes 20 formed on its lower side, and the punching hole 8 and the waste holes 20 are interconnected; this facilitates the recycling of punching waste, allowing the waste to leave the lower die 2 in a timely manner and avoid affecting the next punching action.

[0045] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
