Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more specifically to a multi-core stamping die for automobile parts. Background Art

[0002] In recent years, the automotive industry has continuously increased its requirements for lightweighting. Aluminum profiles not only meet the demand for lightweighting, but also have higher rigidity. They have begun to be widely used in the load-bearing structural parts of automobiles. Stamping dies are a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during stamping. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material to cause separation or plastic deformation, thereby obtaining the required parts.

[0003] The defects of the existing stamping die are:

[0004] 1. Most of the existing molds are single-core stamping operations during stamping, which is relatively slow in efficiency;

[0005] 2. When stamping, if the existing mold is blown out and rebounds, mold parts are broken and dropped, screws protrude from the mold surface or other objects enter the mold, or waste materials fall into the mold and are not cleaned up in time, the subsequent stamping process may damage the lower mold, stripper plate, and punch;

[0006] 3. When fixing the lower die, the existing stamping mold uses springs and extrusion blocks to squeeze the two sides of the lower die. Although this fixing method can quickly disassemble the lower die, it has defects. It is easy to cause the die to shift, resulting in the punch head being unable to align with the lower die, affecting the stamping quality of the stamping die.

[0007] To this end, in response to the above-mentioned defects, this solution proposes a multi-core stamping die for automotive parts. Utility Model Content

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0036] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0037] See also Figures 1-4 , a multi-mode core stamping die for automotive parts, comprising a stamping base 1, a placement groove 2 is opened at the upper end of the stamping base 1, a lower die 3 is installed inside the placement groove 2, a plurality of columns 4 are fixedly connected to the upper edge end of the stamping base 1, a sliding sleeve 5 is provided on the outer end of the column 4, a cylinder part 6 is installed on the inner top end of the sliding sleeve 5, an upper die 7 is fixedly connected to the lower end of the cylinder part 6, a hydraulic rod 71 is installed between the upper die 7 and the cylinder part 6, a limiting member 8 is movably connected to the side wall of the placement groove 2, an air pump 10 is also installed on the upper end of one side of the stamping base 1, and a chip box 11 is fixedly connected to the left end of the stamping base 1.

[0038] More specifically, a blanking chute 12 is provided at the bottom end of the placement groove 2 , and the blanking chute 12 is located at the lower side of the limiting member 8 .

[0039] During the use of this solution, in order to avoid the existing mold from being damaged during stamping due to the product being blown out and rebounding, mold parts being broken and falling, screws protruding from the mold surface or other objects entering the mold, or waste falling into the mold and not being cleaned up in time, resulting in damage to the lower mold, stripper plate, and punch during subsequent stamping;

[0040] In addition, the existing stamping mold uses springs and extrusion blocks to squeeze the two sides of the lower mold when fixing the lower mold. Although this fixing method can quickly disassemble the lower mold, it has defects. It is easy to cause the mold to shift, resulting in the punch head being unable to align with the lower mold, affecting the stamping quality of the stamping die.

[0041] To this end, in this embodiment, the mold is clamped and positioned by adopting a method that allows the lower mold to be quickly disassembled and replaced, thereby ensuring the quality of the stamping mold and avoiding the phenomenon of mold deviation. At the same time, the inside of the mold can be actively cleaned before and after stamping to ensure the cleanliness of the inside of the mold, avoid waste material from entering and causing damage to the lower mold, stripper plate, punch and other components during stamping, and ensure the safety of stamping;

[0042] During use, the personnel can first place the lower mold inside the placement groove 2. In this embodiment, the lower mold is detachable, one side of which is hollowed out, and the other side is installed on the surface of the limiter 1 8. During use, the lower mold 3 with the hollowed-out side is placed in the placement groove 2, and then the limiter 1 8 is rotated, and the limiter 2 9 is driven to fit the hollowed-out side of the lower mold 3 until the two are tightly fixed, so as to ensure the quality of subsequent stamping;

[0043] Then the personnel drives the cylinder part 6 to drive the upper mold 7 to move to the side of the lower mold 3 for stamping. If waste material falls into the interior of the lower mold 3 during the stamping process, the personnel can rotate the limiter 2 9 to make the side of the lower mold 3 hollow again, and at the same time start the air pump 10. Under the action of air pressure, the waste material inside the lower mold 3 is blown to the side of the limiter 2 9. Since the blanking chute 12 is set at a low position, the waste material is blown from the blanking chute 12 to the inside of the chip collection box 11 for collection. Then the limiter 2 9 is driven to the side of the lower mold 3 to fit together, and the stamping operation is continued.

[0044] In this embodiment, one side of the lower die of all subsequent stamping types can be set to a hollow shape, which not only reduces the cost of raw materials for production, but also makes it easier to replace the die inside the placement groove 2 and subsequently clean up the internal waste.

[0045] Among them, all the mold cores in this embodiment are arranged in double rows symmetrically, which can improve production efficiency during stamping, avoid shape deviation caused by sliding, and ensure the processing quality of parts.

[0046] See also Figure 1-Figure 3 The limiting member 8 includes a limiting plate 81 rotatably connected to the inner wall of the placement groove 2, and a through hole 82 is opened at the center end of the limiting plate 81. The through hole 82 is T-shaped, and the limiting member 9 is installed through the inner wall of the through hole 82.

[0047] More specifically: the limiting member 2 9 includes a threaded rod 91 threadedly connected between the inner walls of the through hole 82, the front end of the threaded rod 91 is rotatably connected to the limiting plate 2 92, and the rear end of the threaded rod 91 is fixedly connected to the limiting handle 93, and the limiting handle 93 is interlocked with the rear inner wall of the through hole 82. The outer end of the limiting plate 1 81 is rotatably connected to a cover 94, and the cover 94 is located on the upper side of the through hole 82.

[0048] During use of this solution, when the personnel need to replace the lower mold 3 or clean the internal waste, the personnel can first insert the hexagonal wrench or the electric hexagonal drill into the limit handle 93. At this time, one side of the limit plate 2 92 is attached to the hollow side of the lower mold 3, and the limit handle 93 is embedded in the inside of the through hole 82. Then the threaded rod 91 is driven to reverse, causing the limit plate 2 92 to continuously move away from the lower mold 3. At this time, the personnel can start the air pump 10 to blow the waste inside the lower mold 3, so that the waste falls into the blanking chute 12 below the limit piece 2 9, and until it falls into the inside of the chip collection box 11 for collection;

[0049] The subsequent personnel can continue to reverse the threaded rod 91 to make the second limiting plate 92 stick to the surface of the first limiting plate 81. At this time, the personnel can rotate the first limiting plate 81, and the first limiting plate 81 and the second limiting plate 92 are completely separated from the inner wall of the placement groove 2. The personnel can then take out the lower mold 3 for replacement.

[0050] In this embodiment, when the personnel rotate the limit plate 2 92 to fit the side of the lower mold 3, the limit handle 93 is embedded in the through hole 82. At this time, the personnel flip the cover 94 to make the cover 94 cover the outside of the through hole 82, thereby further enhancing the stability of the mold.

[0051] See also Figures 1-4 The upper end of the front side of the stamping base 1 is fixedly connected to a transmission base 13, and the upper end of the transmission base 13 is rotatably connected to a limiting clamp 14, and the inner diameter of the limiting clamp 14 coincides with the outer diameter of the limiting member 8.

[0052] During the use of this solution, when the personnel are performing stamping work, in order to further improve the quality and stability of stamping, in this embodiment, when the limit member 8 rotates to a horizontal plane between the inner walls of the placement groove 2, the limit clamp 14 is flipped over to cause the limit clamp 14 to be mounted on the outside of the limit member 8, thereby positioning the position of the limit member 8 so that it will not deviate during stamping, thereby ensuring the stability and quality of stamping.

[0053] See also Figure 1-Figure 2 The outer end of the column 4 is provided with a plurality of spherical grooves, and balls are rotatably connected between the inner walls of the spherical grooves, and the balls are in contact with the inner wall of the sliding sleeve 5.

[0054] During use, this solution installs a plurality of balls on the outer side of the column 4, so that when the sleeve 5 slides up and down, the guiding accuracy of the mold is first improved under the action of the column 4, and the friction between the two is reduced during the operation of the balls, thereby improving the durability and accuracy of the mold, thereby improving the dimensional accuracy of the parts and improving the production efficiency of parts processing.

[0055] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
