[0040] Specifically, the working principle of the automobile front floor stamping die of the quick stripping and guiding composite of the embodiment is as follows:

[0041] Before stamping the material, under the action of the first spring 41, the guiding pin 91 of the supporting seat 5 is located at the top of the first guiding vertical groove 33, and under the action of the third spring 63, the limiting pin 92 is located at the bottom of the first limiting inclined groove 51.

[0042] When the material is placed on the lower die 2, the upper die 11 drives the material to move downward, the material is pressed on the friction plate 6, the first spring 41 and the second spring 71 are compressed, the limiting pin 92 is kept at the bottom of the first limiting inclined groove 51, and the guiding pin 91 enters the second guiding inclined groove 32 through the first guiding inclined surface 35, then the guiding pin 91 moves downward along the second guiding inclined groove 32, at this time, because the compression amount of the second spring 71 is larger, the friction force between the friction plate 6 and the material is larger, so the material moves along the X-axis direction through the friction plate 6 in the moving process of the sliding seat 4;

[0043] Until the material abuts against the blocking boss 8, the material cannot continue to move along the X-axis direction, and at this time, due to the large compression amount of the second spring 71, the friction between the friction plate 6 and the material is still relatively large, and the sliding seat 4 is subjected to the pressure of the material, so that the sliding seat 4 continues to move along the X-axis direction, that is, the relative movement between the sliding seat 4 and the support occurs, at this time, the limiting pin 92 moves upward along the first limiting inclined groove 51 to the top of the limiting vertical groove 53, and then falls to the bottom of the limiting vertical groove 53, at this time, due to the height of the bottom of the limiting vertical groove 53 is lower than the height of the bottom of the first limiting inclined groove 51, so the compression amount of the second spring 71 is smaller, so that the friction between the friction plate 6 and the material is reduced, at this time, the sliding seat 4 can drive the support seat 5 to continue to move along the X-axis direction;

[0044] Until the guide pin 91 moves to the second guide vertical groove 34, the upper die 11 continues to press the material, the guide pin 91 moves to the bottom of the second guide vertical groove 34, and the stamping process of the material is completed.

[0045] After stamping, the mold is opened, under the action of the first spring 41, the second spring 71 and the third spring 63, the guide pin 91 of the support seat 5 moves to the top of the first guide vertical groove 33, and the limiting moves to the bottom of the first limiting inclined groove 51, and can effectively remove the material.

[0046] The embodiment can realize the integration of the guiding and stripping functions by the sliding device 21 for initial positioning of the material before the mold is closed, and not interfering with the forming area during the mold closing process, and the demolding efficiency is significantly improved and the risk of part deformation is reduced during demolding, thereby realizing the integration of the guiding and stripping functions, and meeting the high-efficiency stamping forming demand of complex curved surface parts.
