Detailed Embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figure 1-3 As shown in the figure, a stripping device for a stamping die of an automotive part includes a lower die 1 and an upper die 2. A die groove 3 is formed at the top of the lower die 1. A blank holding component 4 is installed at the top of the lower die 1. A material pushing mechanism 5 is installed at the rear of the blank holding component 4. The blank holding component 4 includes two top plates 6. The two top plates 6 are respectively movably arranged on both sides of the top of the lower die 1. Chute grooves 7 are formed at the inner sides of the tops of the two top plates 6. Limit grooves 8 are formed on both sides of the top of the lower die 1. At the front and rear ends of the bottom of the top plate 6, ejector rods 9 are fixedly installed. A spring 10 is sleeved on the periphery of the ejector rod 9. A chassis 11 is fixedly installed at the bottom of the ejector rod 9.

[0022] In this embodiment, the two top plates 6 are symmetrically arranged with each other. The top plates 6 are arranged in a matching manner within the limit grooves 8. The workpiece to be stamped is located between the chute grooves 7 of the two top plates 6. During stamping, the top plates 6 are contracted through the limit grooves 8, so that the top plates 6 are at the same horizontal plane as the top of the workpiece.

[0023] In this embodiment, the four ejector rods 9 are arranged in a rectangular pattern. The ejector rods 9 penetrate through the inside of the lower die 1 and are arranged to slide up and down. The top plates 6 are pushed upward by the elastic force of the springs 10, and at the same time, the ejector rods 9 slide upward for support, facilitating the automatic demolding of the workpiece.

[0024] In this embodiment, the diameter of the chassis 11 is larger than the cross-sectional diameter of the ejector rod 9. The top of the ejector rod 9 is perpendicular to the top plate 6. The ejector rod 9 is limited by the chassis 11 to prevent it from popping out and detaching.

[0025] In this embodiment, the material pushing mechanism 5 includes a fixing plate 12. The fixing plate 12 is fixedly installed at the rear ends of the two top plates 6. A cylinder 13 is installed at the rear of the fixing plate 12. A telescopic rod 14 is arranged at the front end of the cylinder 13 and penetrates through the front part of the fixing plate 12. A push plate 15 is installed between the front ends of the telescopic rod 14 and within the two chute grooves 7. The push plate 15 slides back and forth through the cylinder 13, facilitating the automatic stripping of the workpiece.

[0026] In this embodiment, the fixing plate 12 and the top views of the two top plates 6 are arranged in a "冂" shape. The front end of the telescopic rod 14 is fixedly installed with the push plate 15. During the back-and-forth sliding of the push plate 15, the workpiece slides between the two chute grooves 7 for automatic material pushing.

[0027] In this embodiment, the push plate 15 is arranged to slide back and forth between the two chute grooves 7. The push plate 15 slides through the expansion and contraction of the telescopic rod 14 to push the workpiece.

[0028] It should be noted that the utility model is a material stripping device for a stamping die for automobile parts. When in use, the workpiece to be stamped is first placed between the two slide grooves 7, and the upper die 2 is pressed down to make the workpiece pass through the die groove 3 for stamping. During the stamping process, the upper die 2 drives the two top plates 6 and the workpiece to descend, so that the top rod 9 passes through the interior of the lower die 1 and slides downward. At the same time, the spring 10 contracts, so that the top plate 6 is located in the limiting groove 8 and is at the same horizontal plane as the top of the workpiece, and stamping is performed. After the stamping is completed, the upper die 2 is separated from the lower die 1, and the two top plates 6 are bounced up under the action of the spring 10, and the corners of the workpiece are supported and separated from the die groove 3. When stripping the material, the telescopic rod 14 is extended forward by starting the cylinder 13, and the push plate 15 is driven to push the workpiece forward, so that the workpiece is automatically demolded.
