Description

Technical Field

[0001] This utility model relates to the field of die forging forming mold technology, and more specifically, to a closed die forging forming mold for precision forging of vehicle parts. Background Technology

[0002] Vehicle precision forgings refer to automotive parts manufactured through precision forging processes. Precision forging is a metal plastic processing technique that uses pressure to cause plastic deformation of a metal billet in a die, thereby obtaining high-precision, high-strength, and high-performance forgings.

[0003] Closed-die forging is a precision forging process in which the metal billet is deformed under pressure in a closed die cavity. Excess material will form flash (which needs to be removed later). Through flash-free design (or minimal flash): unlike traditional open-die forging, closed-die forging reduces material waste by precisely controlling the matching of the billet volume with the cavity.

[0004] Among them, the patent with publication number CN214349363U discloses a forging forming mold, including an upper mold and a lower mold. The upper mold has a protrusion and a forming groove extending upward from the lower end surface along its height direction. The forming groove is used to form the reinforcing ribs of the forging. The lower mold has a mold cavity that matches the protrusion, and the height of the protrusion is less than the depth of the mold cavity.

[0005] When in use, this structure allows the protrusion of the upper die to cooperate with the cavity of the lower die to form a closed precision forging. This is used to solve the problems in the existing technology of insufficient filling of the ribs in the cup-shaped forging with reinforcing ribs, which easily causes chipping and folding defects, and titanium alloy forgings sticking to the upper die. However, the single upper and lower die extrusion method also causes the product to have insufficient metal fluidity, resulting in incomplete filling of corners or ribs, uneven stress distribution, and internal voids, shrinkage, or cracks. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a closed-die forging mold for vehicle precision forging parts, which aims to solve the problems mentioned in the background art.

[0007] This utility model provides the following technical solution: a closed-die forging mold for vehicle precision forging parts, including a base, on which a pressure forming component is provided;

[0008] The pressure molding assembly includes a pressure plate disposed on the top of the base, an upper mold body disposed at the bottom of the pressure plate, and a lower mold body disposed at the bottom of the upper mold body;

[0009] A guide seat is slidably connected to the outer side of the upper mold body. The guide seat is fixed to the bottom of the pressure plate. A triangular seat is slidably connected inside the guide seat. The triangular seat is located at the top of the upper mold body.

[0010] The top of the triangular seat is provided with a push plate, which is inserted into the guide seat and slidably connected to the guide seat. The vertical cross-sectional shape of the triangular seat is set as a triangle, and one end of the push plate extends to the top of the triangular seat and is slidably connected to the triangular seat.

[0011] As can be seen, in the above technical solution, the output end of the first hydraulic rod pulls the pressure plate, causing the guide seat and the upper mold body to move downward to press the lower mold body and form the mold material. At the same time, the push plate is driven by the second hydraulic rod to slide on the guide seat. When the guide seat moves, it abuts against the triangular seat, which allows the triangular seat and the upper mold body to move downward a second time in the middle of the guide seat due to the traction force of the push plate displacement. This achieves the function of pressing the mold material in the lower mold body a second time, ensuring the molding quality. In addition, during the process of the upper mold body pressing the lower mold body downward, the outer side of the upper mold body contacts the pressure plate, which also facilitates the removal of excess mold material.

[0012] Optionally, in a possible implementation, a connecting seat is provided on the outer side of the lower mold body. The connecting seat is bolted to the top of the base. Electric slide rails for guidance are provided on both sides of the inner wall of the connecting seat, and a sliding plate is slidably connected between the two electric slide rails. The sliding plate is bolted to the bottom of the lower mold body. Two first hydraulic rods are embedded at one end of the connecting seat, and the output end of each first hydraulic rod extends to the pressure plate. A second hydraulic rod is bolted to one side of the pressure plate, and the output end of the second hydraulic rod extends to the push plate. The upper mold body and the lower mold body are stacked, and weight reduction openings are provided on the outer sides of both the upper mold body and the lower mold body.

[0013] As can be seen, in the above technical solution, the electric slide rail drives the slide plate to move the lower mold body, which in turn allows the lower mold body to extend to the outside of the connecting seat, so that the operator can place the mold material on the lower mold body. After that, the electric slide rail drives the slide plate to reset the lower mold body, so that the lower mold body is transferred to the bottom of the upper mold body.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] By setting up a pressure forming component, the overall design is simple. Through the corresponding cooperation of various structures, the output end of the first hydraulic rod pulls the pressure plate, which drives the guide seat and the upper mold body to move downward, thus pressing the lower mold body and forming the mold material.

[0016] At the same time, the push plate is driven by the second hydraulic rod to slide on the guide seat. When the guide seat moves, it abuts against the triangular seat, which in turn allows the triangular seat and the upper mold body to move downward twice in the middle of the guide seat due to the traction force of the push plate displacement. This achieves the function of applying secondary pressure to the mold material in the lower mold body, ensuring molding quality. Uneven stress distribution can lead to internal voids, shrinkage, or cracks.

[0017] Furthermore, during the process of the upper mold body applying pressure downwards to the lower mold body, the contact between the outer side of the upper mold body and the pressure plate also facilitates the removal of excess mold material. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As attached Figures 1-4The closed-die forging mold for vehicle precision forging parts shown uses a pressure forming component on the base 1. The output end of the first hydraulic rod 8 pulls the pressure plate 2, causing the guide seat 11 and the upper die body 3 to move downwards to pressurize the lower die body 4 and form the die material. At the same time, the second hydraulic rod 9 drives the push plate 10 to slide on the guide seat 11. When the guide seat 11 moves, it abuts against the triangular seat 12, which in turn causes the triangular seat 12 and the upper die body 3 to move downwards a second time in the middle of the guide seat 11 due to the traction force of the push plate 10. This achieves the function of secondary pressure on the die material in the lower die body 4, ensuring the forming quality. In addition, during the process of the upper die body 3 pressing the lower die body 4 downwards, the outer side of the upper die body 3 contacts the pressure plate 2, which also facilitates the removal of excess die material. The specific structural settings of the component are as follows.

[0026] The pressure molding assembly includes a pressure plate 2 disposed on the top of the base 1, an upper mold body 3 disposed at the bottom of the pressure plate 2, and a lower mold body 4 disposed at the bottom of the upper mold body 3;

[0027] A guide seat 11 is slidably connected to the outer side of the upper mold body 3. The guide seat 11 is fixed to the bottom of the pressure plate 2. A triangular seat 12 is slidably connected inside the guide seat 11. The triangular seat 12 is located at the top of the upper mold body 3.

[0028] A push plate 10 is provided on the top of the triangular seat 12. The push plate 10 is inserted into the guide seat 11 and slidably connected to the guide seat 11. The vertical cross-sectional shape of the triangular seat 12 is set as a triangle, and one end of the push plate 10 extends to the top of the triangular seat 12 and slidably connects to the triangular seat 12.

[0029] A connecting seat 5 is provided on the outer side of the lower mold body 4. The connecting seat 5 is installed on the top of the base 1 by bolts. Electric slide rails 6 for guidance are provided on both sides of the inner wall of the connecting seat 5. A slide plate 7 is slidably connected between the two electric slide rails 6. The slide plate 7 is installed on the bottom of the lower mold body 4 by bolts. Two first hydraulic rods 8 are embedded at one end of the connecting seat 5. The output end of each first hydraulic rod 8 extends to the pressure plate 2. A second hydraulic rod 9 is installed on one side of the pressure plate 2 by bolts. The output end of the second hydraulic rod 9 extends to the push plate 10. The upper mold body 3 and the lower mold body 4 are stacked. Weight reduction openings 13 are provided on the outer side of both the upper mold body 3 and the lower mold body 4.

[0030] The specific working principle is as follows: the electric slide rail 6 drives the slide plate 7 to move the lower mold body 4, so that the lower mold body 4 can extend to the outside of the connecting seat 5, so that the operator can place the mold material on the lower mold body 4. Then the electric slide rail 6 drives the slide plate 7 to reset the lower mold body 4, so that the lower mold body 4 is transferred to the bottom of the upper mold body 3.

[0031] By activating the first hydraulic rod 8, the output end of the first hydraulic rod 8 pulls the pressure plate 2, causing the guide seat 11 and the upper mold body 3 to move downwards and pressurize the lower mold body 4 to form the mold material. At the same time, the push plate 10 is driven by the second hydraulic rod 9 to slide on the guide seat 11. When the guide seat 11 moves, it abuts against the triangular seat 12, which in turn causes the triangular seat 12 and the upper mold body 3 to move downwards a second time in the middle of the guide seat 11 due to the traction force of the push plate 10. This achieves the function of pressing the mold material in the lower mold body 4 a second time, ensuring the molding quality. In addition, during the process of the upper mold body 3 pressing the lower mold body 4 downwards, the outer side of the upper mold body 3 comes into contact with the pressure plate 2, which also facilitates the removal of excess mold material.

[0032] Unlike existing technologies, this application discloses a closed-die forging mold for vehicle precision forgings. The output end of the first hydraulic rod 8 pulls the pressure plate 2, causing the guide seat 11 and the upper die body 3 to move downwards and pressurize the lower die body 4 to form the die material. At the same time, the second hydraulic rod 9 drives the push plate 10 to slide on the guide seat 11. When the guide seat 11 moves, it abuts against the triangular seat 12, which in turn causes the triangular seat 12 and the upper die body 3 to move downwards again in the middle of the guide seat 11 due to the traction force of the push plate 10. This achieves the function of secondary pressurization of the die material in the lower die body 4, ensuring the forming quality. Furthermore, during the process of the upper die body 3 pressing the lower die body 4 downwards, the outer side of the upper die body 3 comes into contact with the pressure plate 2, which also facilitates the removal of excess die material.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
