Description

Technical Field

[0001] This application relates to the field of stamping dies, and particularly to a stamping die for a computer backplane. Background Art

[0002] A stamping die for a computer backplane refers to a stamping die specifically used for manufacturing the metal plate (backplane) on the back of a computer case. The computer backplane is a part of the computer case structure, mainly playing the roles of supporting and fixing internal components (such as motherboards, hard drives, power supplies, etc.) and providing external interfaces (such as USB, audio interfaces, etc.). Since the backplane requires precise dimensions, shapes, and various openings, the stamping process has become a common method for manufacturing such components.

[0003] The feeding and discharging of existing stamping dies for computer backplanes are usually carried out manually or by a robotic arm. The stamping forming accuracy of computer backplanes requires a high level, and the position where the blank is placed must be precise. The traditional method is to open a material groove with a certain depth in the lower die insert for positioning. However, the overall computer backplane is relatively thin. If the depth of the material groove is too deep, it is easy to cause difficulties in blanking. If the material groove is too shallow, it is difficult to achieve the effect of rapid positioning, which is rather inconvenient. Utility Model Content

[0004] This application provides a stamping die for a computer backplane.

[0005] The above technical objectives of this application are achieved through the following technical solutions:

[0006] A stamping die for a computer backplane includes an upper module assembly and a lower module assembly. The lower module assembly includes a lower backing plate. A lower die insert is fixedly installed on the top of the lower backing plate. A stamping forming groove is opened on the top of the lower die insert. An installation plate is provided at the bottom of the lower backing plate. A rotating disk is rotatably connected to the middle of the top of the installation plate. A guiding chute is opened on the top of the rotating disk. A limiting chute is opened at the bottom of the lower backing plate. A sliding bar is slidably connected inside the limiting chute. One end of the sliding bar is fixedly installed with a connecting rod at the top, and a guide post is fixedly installed at the bottom of the other end of the sliding bar. A positioning push block is fixedly installed on one side of the connecting rod. The guide post is slidably connected to the guiding chute.

[0007] By adopting the above scheme, since the stamping forming groove is opened on the top of the lower die insert, it is convenient for the blank to be stamped and formed inside the stamping forming groove. Since the rotating disk is rotatably connected to the middle of the top of the installation plate, it is convenient for the rotating disk to rotate in the middle of the installation plate. Since the positioning push block is fixedly installed on one side of the connecting rod and the guide post is slidably connected to the guiding chute, it is convenient for the rotation of the rotating disk to drive the sliding bar to slide along the limiting chute, so that the connecting rod drives the positioning push block to move. During the feeding process, the four positioning push blocks can push the blank to accurately position the position of the blank, thus facilitating the device to stamp and form the blank and improving the finished product rate and production efficiency.

[0008] Further, a worm gear is fixedly installed at the bottom of the rotating disk, and the worm gear is arranged at the bottom of the mounting plate.

[0011] By adopting the above scheme, since a worm is fixedly installed at the output end of the motor and the worm is meshed with the worm gear, it is convenient for the motor to drive the worm to rotate and then drive the worm gear to rotate.

[0012] Further, a lower die base is arranged at the bottom of the mounting plate, and a plurality of support bars are fixedly installed between the mounting plate and the lower die base.

[0013] By adopting the above scheme, since a lower die base is arranged at the bottom of the mounting plate and a plurality of support bars are fixedly installed between the mounting plate and the lower die base, it is convenient for the punching press to be fixedly connected with the lower die base, so as to fixedly install the lower die module assembly on the punching press, which is convenient for punching forming. The support bars are convenient for fixedly connecting the lower die base and the mounting plate, and are also convenient for fixedly installing the motor at the bottom of the mounting plate.

[0014] Further, guide rods are fixedly installed at both ends of the top of the mounting plate. The upper die module assembly includes an upper die base, and guide sleeves are fixedly installed at both ends of the bottom of the upper die base. The guide rods are inserted into the inner parts of the guide sleeves.

[0015] By adopting the above scheme, since guide sleeves are fixedly installed at both ends of the bottom of the upper die base and the guide rods are inserted into the inner parts of the guide sleeves, it is convenient to guide the movement of the upper die module assembly and improve the accuracy of the closing of the upper die insert and the lower die insert.

[0016] Further, an upper backing plate is fixedly installed at the bottom of the upper die base, an upper die insert is fixedly installed at the bottom of the upper backing plate, and a punching forming convex block is arranged at the bottom of the upper die insert.

[0017] By adopting the above scheme, since a punching forming convex block is arranged at the bottom of the upper die insert, it is convenient for the upper die insert to cooperate with the lower die insert to close the die and punch and form the blanking plate.

[0018] Further, through holes are formed in the middle parts of the upper backing plate and the upper die insert, and ejector rods are inserted into the through holes.

[0019] Further, an ejector spring is fixedly installed at the top of the ejector rod, and the top of the ejector spring is fixedly connected with the upper die base.

[0020] By adopting the above scheme, the top of the ejection spring is fixedly connected to the upper die base, which facilitates the ejection spring to eject the ejection rod outward during mold opening, so as to eject the formed part from the bottom of the upper die core for demolding.

[0021] In summary, the present application has the following technical effects:

[0022] By providing a stamping and forming groove at the top of the lower die core, it is convenient for the material plate to be stamped and formed inside the stamping and forming groove. By rotatably connecting a rotating disk in the middle of the top end of the mounting plate, it is convenient for the rotating disk to rotate in the middle of the mounting plate. By fixedly installing a positioning push block on one side of the connecting rod, and the guide post is slidably connected to the guiding chute, it is convenient for the rotation of the rotating disk to drive the sliding bar to slide along the limiting chute, so that the connecting rod drives the positioning push block to move. During the feeding process, the four positioning push blocks can push the material plate to accurately position the position of the material plate, thus facilitating the device to stamp and form the material plate, improving the finished product rate and production efficiency.
