The top-out assembly includes a plurality of top-out columns and a top-out driving part. The top-out columns are arranged along the Y direction. The top ends of the top-out columns movably penetrate through the mold frame and are located at the bottom of the mold cavity groove. The top-out driving part is used to drive the plurality of top-out columns to move in the Y direction.

[0006] As an improvement of the above technical solution: both sides of the inner wall of the mold frame have fitting guide rails. Both sides of the mold cavity groove are provided with notches adapted to the fitting guide rails. The mold cavity groove is slidably connected to the fitting guide rails through the notches.

[0007] As an improvement of the above technical solution: a plurality of limiting holes adapted to the top-out columns are opened at the bottom of the mold frame. A plurality of through grooves adapted to the top-out columns are opened on the bottom seat. Each limiting hole is coaxially aligned with one of the through grooves. The bottom ends of the top-out columns sequentially pass through the limiting holes and the through grooves and then extend below the bottom seat.

[0008] As an improvement of the above technical solution: the top-out driving part includes a first hydraulic cylinder and a top plate. The top plate is fixedly connected to the top output rod of the first hydraulic cylinder. The bottom ends of the plurality of top-out columns are fixedly connected to the top of the top plate.

DETAILED DESCRIPTION

[0019] In order to make the objectives, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Embodiment

[0021] Please refer to Figures 1 - 4 , a cold stamping die for the front section assembly of a new energy vehicle longitudinal beam, comprising a top seat 1 and a bottom seat 5 which are arranged opposite to each other up and down. The bottom of the top seat 1 has a module 2 for stamping the front section workpiece 8 of the longitudinal beam. The top of the bottom seat 5 has a die frame 3. Inside the die frame 3, a cavity groove 9 adapted to the module 2 is inserted along the Y direction. Below the cavity groove 9, an ejection assembly is provided. The ejection assembly includes a plurality of ejection columns 6 and an ejection driving part. The ejection columns 6 are arranged along the Y direction. The top ends of the ejection columns 6 movably penetrate through the die frame 3 and are located at the bottom of the cavity groove 9. The ejection driving part is used to drive the plurality of ejection columns 6 to move in the Y direction.

[0022] In an optional embodiment: both sides of the inner wall of the die frame 3 have fitting guide rails 4. Specifically, the fitting guide rails 4 extend along the Y direction. Both sides of the cavity groove 9 are provided with notches 31 adapted to the fitting guide rails 4. The cavity groove 9 is slidably connected to the fitting guide rails 4 through the notches 31, so that the cavity groove 9 can be stably moved up and down inside the die frame 3 through the fitting guide rails 4.

[0023] In an optional embodiment: a plurality of limit holes 30 adapted to the ejection columns 6 are opened at the bottom of the die frame 3, and a plurality of through grooves 50 adapted to the ejection columns 6 are opened on the bottom seat 5. Each limit hole 30 is coaxially aligned with a through groove 50. The bottom ends of the ejection columns 6 sequentially pass through the limit holes 30 and the through grooves 50 and then extend below the bottom seat 5.

[0024] In an optional embodiment: the ejection driving part includes a hydraulic cylinder 10 and a top plate 101. The top plate 101 is fixedly connected to the top output rod of the hydraulic cylinder 10. The bottom ends of the plurality of ejection columns 6 are fixedly connected to the top of the top plate 101. A driving mechanism is provided on the top of the top seat 1. The driving mechanism is used to drive the top seat 1 to move in the Y direction. The driving mechanism can be a hydraulic cylinder in the prior art, that is, the driving mechanism can drive the top seat 1 to move towards the bottom seat 5, so that the module 2 stamps the front section workpiece 8 of the longitudinal beam.

[0025] In an alternative embodiment: Guide posts 11 are provided at the four corners of the bottom of the top seat 1, and guide sleeves 51 adapted to the guide posts 11 are provided at the four corners of the top of the base seat 5. When the bottom end of the guide post 11 can be inserted into the inner side of the guide sleeve 51, when the module 2 just finishes stamping the front-section workpiece 8 of the longitudinal beam, the bottom end of the guide post 11 contacts the inner bottom end of the guide sleeve 51, so as to play a good limiting role between the top seat 1 and the base seat 5 through the guide post 11 and the guide sleeve 51, and avoid damage to the guide post 11 due to excessive stamping.

[0026] In an alternative embodiment: A plurality of pressure posts 7 are provided at the bottom of the module 2, and a plurality of bottom grooves 90 adapted to the pressure posts 7 are provided at the top of the die cavity groove 9. Each pressure post 7 corresponds coaxially to a bottom groove 90 and a through hole 80 provided on the front-section workpiece 8 of the longitudinal beam. Specifically, when normally entering the die cavity groove 9 through the die frame 3 to stamp the front-section workpiece 8 of the longitudinal beam, the pressure posts 7 can sequentially pass through the through hole 80 and the bottom groove 90 without affecting the stamping of the front-section workpiece 8 of the longitudinal beam. After the stamping of the front-section workpiece 8 of the longitudinal beam is completed, when the die cavity groove 9 and the front-section workpiece 8 of the longitudinal beam are jacked upward, the top seat 1 can be driven to move downward to drive the pressure posts 7 to move downward synchronously. The main purpose is to let the pressure posts 7 enter the bottom grooves 90 to push the die cavity groove 9 downward to its original position in the die frame 3, rather than pushing the die cavity groove 9 for resetting through the module 2. Because after the top seat 1 is driven to move downward for a certain distance, the top seat 1 will be limited by the guide post 11 and the guide sleeve 51, so that there is a certain distance (i.e., the thickness of the front-section workpiece 8 of the longitudinal beam) between the bottom surface of the module 2 and the inner bottom surface of the die frame 3, making the module 2 unable to continue to push the die cavity groove 9 downward. At this time, the pressure posts 7 enter the bottom grooves 90 to push the die cavity groove 9, so that the die cavity groove 9 is reset in the die frame 3. The pressure posts 7 can be made of rigid materials or elastic materials. The elastic materials are used to make the pressure posts 7 better extrude and push the die cavity groove 9.

[0027] Specifically, before stamping the front-section workpiece 8 of the longitudinal beam, first place the front-section workpiece 8 of the longitudinal beam into the die cavity groove 9 on the die frame 3, and then drive the top seat 1 and the module 2 to move downward through the driving mechanism, so as to effectively stamp and form the front-section workpiece 8 of the longitudinal beam through the cooperation of the module 2 and the die cavity groove 9;

[0028] After the stamping and forming of the front-section workpiece 8 of the longitudinal beam is completed, first move the top seat 1 away from the base seat 5, and then drive a plurality of ejector posts 6 on the top plate 101 to move upward through the hydraulic cylinder 10, so that the bottom end of the ejector post 6 can contact the bottom end of the die cavity groove 9, and the die cavity groove 9 and the front-section workpiece 8 of the longitudinal beam slide upward inside the die frame 3 and gradually disengage from the die frame 3, and the fitting guide rail 4 no longer blocks the notch 31 on the die frame 3. At this time, it is convenient to take out the front-section workpiece 8 of the longitudinal beam from the original die cavity groove 9 inside the die frame 3, which is time-saving and labor-saving.

[0029] When the taking-out is completed, the top seat 1 can be pushed downward to drive the pressure column 7 to move downward synchronously. Mainly, the pressure column 7 enters the bottom groove 90 to push the die cavity groove 9 downward to the original position in the die frame 3, which is convenient for preparing the next stamping and forming of the workpiece, saving time and effort and improving work efficiency.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
