Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figure 1-7 As shown, a side-flipping mechanism for a stamping die for an automotive inner panel reinforcement includes a lower die assembly 1 and an upper die assembly 2, with a side-flipping component provided between the lower die assembly 1 and the upper die assembly 2.

[0030] The side-flanging assembly includes multiple demolding cylinders 3 fixedly connected to the lower mold assembly 1. The multiple demolding cylinders 3 can lift the formed automotive inner panel reinforcement upward after the stamping and flanging is completed, thereby realizing the rapid demolding of the automotive inner panel reinforcement. Thus, the output ends of the multiple demolding cylinders 3 face upward and are fixedly connected to two side-flanging modules 4. The side-flanging module 4 includes a mounting frame 41, on which multiple side-flanging molds 42 are evenly fixedly connected. Multiple side-flanging punches 5 are installed between the two side-flanging modules 4. A pressure module 6 is fixedly connected to the lower side of the upper mold assembly 2.

[0031] In the above embodiment, during stamping and flanging, the automotive inner panel reinforcement is placed below the pressure module 6, and the upper die assembly 2 is controlled to move downwards for die closing and stamping. The side flanging die 42 and the side flanging punch 5 cooperate with each other to side-flang the automotive inner panel reinforcement. Since the side flanging module 4 is composed of multiple independent side flanging dies 42, if one or more side flanging dies 42 are damaged, only the damaged side flanging die 42 needs to be replaced to complete the repair of the side flanging stamping die. There is no need to replace the entire side flanging module 4, thereby reducing the repair cost of the side flanging module 4 and effectively reducing the repair cost of the automotive inner panel reinforcement stamping die flanging mechanism.

[0032] The lower mold assembly 1 includes a lower mold base 7. The upper side wall of the lower mold base 7 has multiple mounting slots 8 corresponding to the side flange module 4, the side flange punch 5 and the pressing module 6. The vertical side wall of the lower mold base 7 has multiple guide slots 9. Each of the multiple guide slots 9 has a guide groove 10 installed in it. The guide groove 10 is inclined.

[0033] In the above embodiments, the material guide trough 10 can improve the smoothness and convenience of waste discharge.

[0034] The upper mold assembly 2 includes an upper mold base 11, on which a plurality of stamping holes 12 are provided. The plurality of stamping holes 12 are located above the side flange module 4, the side flange punch 5 and the pressing module 6.

[0035] In the above embodiment, the punching hole 12 facilitates the application of pressure by the punching power source.

[0036] Two positioning plates 13 are symmetrically fixedly connected to the lower side wall of the upper mold base 11, and two positioning grooves 14 corresponding to the positioning plates 13 are symmetrically opened on the upper side wall of the lower mold base 7. The two positioning plates 13 are respectively movably inserted into the two positioning grooves 14.

[0037] In this embodiment, the positioning plate 13 and the positioning groove 14 cooperate with each other to guide the lower die assembly 1 and the upper die assembly 2, thereby improving the accuracy of the stamping die closing and the stamping accuracy of the automotive inner panel reinforcement stamping die when stamping the automotive inner panel reinforcement.

[0038] The vertical sidewalls of the lower mold base 7 and the upper mold base 11 are each fixedly connected to two U-shaped ear plates 15, and pins 16 are fixedly connected to the U-shaped ear plates 15.

[0039] In this embodiment, the U-shaped ear plate 15 and the pin 16 cooperate with each other, which can improve the convenience of connecting the stamping die with other equipment, thereby improving the convenience of stamping die installation.

[0040] The lower mold base 7 has multiple limiting plates 17 fixedly connected to its vertical sidewall, and the upper mold base 11 is located between the multiple limiting plates 17.

[0041] In the above embodiments, the multiple limiting plates 17 can limit and guide the upper mold base 11, thereby improving the accuracy of the stamping die closing and the stability of the stamping die operation.

[0042] The pressing module 6 includes a pressing template 18 fixedly connected to the lower side of the upper mold base 11, and a plurality of pressing blocks 19 are fixedly connected to the side wall of the lower side of the pressing template 18.

[0043] In this embodiment, the pressure template 18 and pressure block 19 can limit and fix the automotive inner panel reinforcement, preventing it from shaking during processing. This improves the stability of the automotive inner panel reinforcement during flanging and effectively enhances the forming quality of the automotive inner panel reinforcement.

[0044] The lower mold base 7 is symmetrically and fixedly connected to a skirt plate 20, and the skirt plate 20 is evenly provided with a plurality of pin holes 21.

[0045] In this embodiment, the skirt plate 20 and pin hole 21 can improve the stability of the fixed connection of the lower mold base 7 and improve the convenience of operation when installing the lower mold assembly 1.

[0046] The lower mold base 7 has fixed plates 22 fixedly connected to the side walls on both the left and right sides, and a triangular rib plate 23 is fixedly connected between the upper side wall of the fixed plate 22 and the lower mold base 7.

[0047] In this embodiment, the fixed plate 22 can improve the convenience of installing and fixing the lower mold base 7, and the triangular rib plate 23 can reinforce the connection between the fixed plate 22 and the lower mold base 7.

[0048] A triangular reinforcement member 24 is fixedly connected between the upper side wall of the skirt plate 20 and the vertical side wall of the lower mold base 7.

[0049] In the above embodiments, the triangular reinforcement member 24 can reinforce the connection between the skirt plate 20 and the lower mold base 7, effectively improving the stability of the connection between the skirt plate 20 and the lower mold base 7.

[0050] The working principle of this utility model is as follows:

[0051] During stamping and flanging, the automotive inner panel reinforcement is placed below the pressure module 6. After the upper die assembly 2 moves downward, the die is closed for stamping. The side flanging die 42 and the side flanging punch 5 work together to side-flang the automotive inner panel reinforcement. Since the side flanging module 4 is composed of multiple independent side flanging dies 42, if one or more side flanging dies 42 are damaged, only the damaged side flanging die 42 needs to be replaced to complete the repair of the side flanging stamping die. There is no need to replace the entire side flanging module 4, which reduces the repair cost of the side flanging module 4 and effectively reduces the repair cost of the flanging mechanism of the automotive inner panel reinforcement stamping die. After flanging is completed, the upper die assembly 2 is pulled upward. The multiple demolding cylinders 3 can push the formed automotive inner panel reinforcement upward, thereby realizing the rapid demolding of the automotive inner panel reinforcement and completing the stamping and flanging of the automotive inner panel reinforcement.

[0052] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.
