[0002] A product in a certain company's project required a trimming operation. Due to the product's limited angles, conventional drive design was not feasible. This process involved trimming, punching, and side trimming. The side trimming angle at the required trimming location was nearly parallel to the panel edge and tilted toward the interior of the product.
[0003] In many medium and large panels, the trimming content is far away from the edge of the panel, and the trimming angle is often too close to the inside of the panel. In this case, the traditional trimming mechanism cannot be designed or the structural space occupied will be very large, resulting in the inability to arrange more work content in the first-order mold, increasing the mold cost.

During the blanking process of the side wall of the panel, the slider is guided by the guide plate assembly and the side baffle installed on the side to define the stamping operation direction.
[0009] In a preferred embodiment of the above solution, the guide plate assembly includes a guide plate and an anti-side guide plate. The slider is T-shaped, and the side trimming insert is fixedly installed at the free end of the vertical side of the T-shaped slider. The anti-side guide plate is arranged on the end face at the lower end of the horizontal side, and the guide plate is arranged on the vertical side opposite to the anti-side guide plate.

During the punching process of the cover part's sidewalls, the embedded side trimming mechanism, in conjunction with the punch 1 and upper die frame 2, allows the trimming of the part to be completed in one go during the forming and punching process. The technical solution provided by the present application is based on the existing stamping mechanism including a press, an upper die frame and a press, and is combined with the structural feature that the press is arranged on the press through the upper die frame. The composite mold of the present application is formed by adding an embedded side trimming mechanism, and the embedded side trimming mechanism is arranged on the press and the upper die frame in a manner that is adapted to the position of the content that needs to be trimmed of the part; then, during the punching process of the side wall of the cover, the content that needs to be trimmed of the part is trimmed in one go through the embedded side trimming mechanism with the cooperation of the press and the upper die frame during the forming and punching process. This solves the technical problem in the prior art that when the angle of the product is limited and the angle limitation is very large, multiple processes are required to complete the trimming work. The embedded side trimming mechanism of the composite mold of the present application can complete the trimming work in one go during the forming and punching process, which not only saves mold space, but also makes the mold utilization rate of a single process higher, and arranges more work content, thereby achieving the purpose of cost saving.

The side trimming insert 4 is movably and fixedly installed on the blank holder 1 through the installation structure, and the return reset guiding structure is arranged on the upper die holder 2 in a position corresponding to the installation structure. Preferably, the installation structure includes a slider 5, a guide plate assembly, and a driving seat 12. The guide plate assembly is arranged on the slider 5, and the side trimming insert 4 is fixedly installed at the front end of the slider 5. The slider 5 is arranged on the blank holder 1 through a limit screw 7 in cooperation with the return reset guiding structure. The driving seat 12 is arranged on the upper die holder 2 in a position corresponding to the slider 5. During the punching process of the side wall of the panel, the slider 5 defines the stamping operation direction under the guidance of the side baffle 3 installed on the side through the guide plate assembly. The return reset guiding structure includes a driving guide plate 10, a forced pull-back hook 11, and a nitrogen spring 6. The forced pull-back hook 11 and the driving guide plate 10 are fixedly installed on the driving seat 12 in a mutually adapted position. Nitrogen springs 6 are respectively arranged on the horizontal sides on both sides of the vertical side of the T-shaped slider. The forced pull-back hook 11 is movably connected to the middle of the horizontal side of the slider through the convex hook at its front end in cooperation with the driving guide plate 10.
[0019] More specifically, the guide plate assembly includes a guide plate 8 and an anti-side guide plate 9. The slider 5 is T-shaped, and the side trimming insert 4 is fixedly installed at the free end of the vertical side of the T-shaped slider.

[0020] In summary, the composite die of this application can adapt to more situations compared with the traditional structure, saves die space, makes the utilization rate of the single-process die higher, arranges more work content, and thus achieves the purpose of cost saving.
[0021] The technical solution of this application will be further described below through specific embodiments:
[0022] The side trimming insert, guide plate, anti-side guide plate, and nitrogen spring are installed on the slider. The slider is inserted into the press from the side. The side baffle is installed on the side to ensure that the side trimming insert of the working part moves in the stamping direction. Finally, the limit screw is installed through the slider and installed on the press. The limit screw restricts the slider in the press to ensure the slider travel and prevent it from falling off. The forced pull-back hook and drive guide are installed on the drive seat and locked to the upper die frame as a whole, playing a driving role in the entire movement process.
[0023] Example 1
[0024] During the die stamping process, the upper die frame follows the upper slider of the press to move downward, driving the drive seat and drive guide. When the drive guide contacts the slider, the drive slider passes through the restrictions of the guide and side baffles and moves in the lower left stamping direction shown in the figure, driving the side trimming insert to complete the trimming work. At this time, the nitrogen spring is in a compressed state, and the forced pull-back hook plays a safety role in the entire movement process, preventing the drive seat and slider from separating during operation. During the mold opening process, the upper die frame follows the upper slider of the press to move upward, driving the drive seat and drive guide to move upward. The slider is not subject to the driving force. At this time, the force of the nitrogen spring will be released, driving the slider back until the retraction nitrogen spring stroke is fully released, completing the trimming work.
