Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to a stamping die for producing crossbeam connecting plates. Background Technology

[0002] The automotive crossbeam connecting plate is an important component of the automotive frame. It is a connecting structure of the entire frame and is mainly used to connect the crossbeams of the frame. Through riveting and other methods, it ensures sufficient strength and rigidity to withstand the load of the vehicle and the impact from the wheels, thereby ensuring the torsional rigidity of the frame and bearing longitudinal loads, and supporting the vehicle's key components.

[0003] In the prior art, Chinese utility model patent with publication number "CN219664912U" and patent name "a stamping die for producing a crossbeam connecting plate" discloses a stamping die for producing a crossbeam connecting plate. The patent describes a technical solution such as "by setting a telescopic cylinder to drive the mounting plate to move, and then by driving the stamping die to move downward through the mounting plate, it is convenient to stamp the connecting plate. By setting a first spring and a limiting rod, the first spring will undergo elastic deformation when the stamping die is pressed down. When the mounting plate rises, the first spring will drive the stamping die to press down again to achieve the effect of multiple stamping, so as to fully process the connecting plate".

[0004] However, after the stamping die completes the stamping process of the crossbeam connecting plate, the stress generated during the stamping process causes the friction of the crossbeam connecting plate in the lower die cavity to increase. This makes it difficult for the upper and lower dies to quickly remove the formed crossbeam connecting plate from the die cavity after the die is opened, which inconveniences the quick demolding operation of the stamping die and reduces production efficiency.

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a stamping die for the production of crossbeam connecting plates. Utility Model Content

[0006] The main purpose of this utility model is to provide a stamping die for the production of crossbeam connecting plates, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A stamping die for producing a crossbeam connecting plate includes an upper die and a lower die. A pressure die is fixedly connected to the bottom surface of the upper die, and a cavity is formed on the top surface of the lower die. A demolding mechanism is located inside the lower die and below the cavity. The demolding mechanism includes a bidirectional screw, a drive motor, extrusion blocks, guide rods, compression springs, a movable plate, ejector rods, and pressure blocks. The bidirectional screw is movably connected to the inside of the lower die via rotating rods at both ends. The drive motor is fixedly connected to the bottom of the side wall of the lower die, and its output end is fixedly connected to the rotating rods. Two extrusion blocks are movably connected to the bidirectional screw via screw holes on the side wall of the bottom slider. Two sets of symmetrical guide rods are also fixedly connected inside the lower die, and compression springs are sleeved on the outside of the guide rods. The movable plate is movably connected to the guide rods via guide holes on both sides and fixedly connected to the bottom end of the compression springs. Two sets of symmetrical ejector rods are fixedly connected to the top surface of the movable plate, and a set of symmetrical pressure blocks corresponding to the extrusion blocks are fixedly connected to the bottom surface of the movable plate.

[0009] Preferably, a set of symmetrical ejection holes are provided on the left and right sides of the inner bottom surface of the mold cavity, a movable cavity is provided on the side wall of the lower mold, and a sliding opening is provided on the inner bottom surface of the movable cavity. Rotation holes are provided on the left and right end walls of the sliding opening.

[0010] Preferably, rotating rods are fixedly installed at the left and right ends of the bidirectional screw, and the rotating rods are movably installed in the rotating hole. The drive motor is fixedly installed at the bottom of the left side wall of the lower mold, and the output end of the drive motor is fixedly installed together with the rotating rod at the left end.

[0011] Preferably, the extrusion block is provided with a set of symmetrical semi-circular shapes, and a slider is fixedly installed on the bottom surface of the extrusion block. The slider is slidably installed in the slide opening, and a screw hole is opened on the side wall of the slider. The slider is threadedly connected to the bidirectional screw through the screw hole.

[0012] Preferably, a set of symmetrical pressure blocks are fixedly installed on the bottom surface of the movable plate, and the pressure blocks are also semi-circular in shape and inverted.

[0013] Preferably, a set of symmetrical guide rods are fixedly installed on the left and right sides of the interior of the movable cavity, and a compression spring is fitted on the outside of the guide rod. The top end of the compression spring is fixedly installed on the top surface of the interior of the movable cavity. Guide holes are opened on the left and right sides of the top surface of the movable plate, and the movable plate is movably installed together with the guide rod through the guide holes. The bottom end of the compression spring is fixedly installed on the top surface of the movable plate. An ejector rod corresponding to the ejector hole is also fixedly installed on the top surface of the movable plate, and the ejector rod is inserted into the ejector hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the demolding mechanism, in conjunction with the stamping die, allows the crossbeam connecting plate to be stamped and formed within the mold cavity via the upper and lower dies. After the upper and lower dies open, the drive motor drives the output end to rotate the bidirectional screw via a rotating rod. This causes the symmetrical extrusion blocks to move in opposite directions through the screw holes on the sidewalls of the bottom slider along the bidirectional screw. During this movement, the pressure block pushes the movable plate upwards. The movable plate moves upwards along the guide rod through the guide hole, forcing the compression spring to retract. This allows the ejector rod to pass through the ejector hole and eject the formed crossbeam connecting plate from the mold cavity. This facilitates rapid ejection and demolding of the formed crossbeam connecting plate, giving the stamping die a rapid demolding function and thus improving production efficiency.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 - Figure 4As shown, a stamping die for producing a crossbeam connecting plate includes an upper die 1 and a lower die 2. A pressure die 3 is fixedly connected to the bottom surface of the upper die 1, and a mold cavity 4 is opened on the top surface of the lower die 2. The lower die 2 is characterized by having a demolding mechanism 5 located inside the lower die 2 and below the mold cavity 4. The demolding mechanism 5 includes a bidirectional screw 10, a drive motor 12, an extrusion block 13, a guide rod 16, a compression spring 17, a movable plate 18, an ejector rod 20, and a pressure block 21. The bidirectional screw 10 is movably connected to the inside of the lower die 2 via rotating rods 11 at both ends. The drive motor 12 is fixedly connected to the bottom of the side wall of the lower die 2. The output end of the drive motor 12 is fixedly connected to the rotating rod 11. The two extrusion blocks 13 are movably connected to the bidirectional screw 10 through the screw holes 15 on the side wall of the bottom slider 14. The interior of the lower mold 2 is also fixedly connected to two sets of symmetrical guide rods 16, and the compression spring 17 is sleeved on the outside of the guide rods 16. The movable plate 18 is movably connected to the guide rods 16 through the guide holes 19 on both sides and fixedly connected to the bottom end of the compression spring 17. The top surface of the movable plate 18 is also fixedly connected to two sets of symmetrical ejector rods 20, and the bottom surface of the movable plate 18 is fixedly connected to a set of symmetrical pressure blocks 21 corresponding to the extrusion blocks 13.

[0023] like Figure 3 As shown, a set of symmetrical ejection holes 6 are respectively opened on the left and right sides of the inner bottom surface of the mold cavity 4. A movable cavity 7 is opened on the side wall of the lower mold 2, and a sliding opening 8 is opened on the inner bottom surface of the movable cavity 7. Rotating holes 9 are respectively opened on the left and right end walls of the sliding opening 8. The movable cavity 7 is used to cooperate with the up and down movement of the movable plate 18, and the sliding opening 8 is used to cooperate with the left and right sliding of the slider 14. The rotating holes 9 are used to cooperate with the rotation of the rotating rod 11.

[0024] like Figure 4 As shown, rotating rods 11 are fixedly installed at the left and right ends of the bidirectional screw 10, and the rotating rods 11 are movably installed in the rotating hole 9. The drive motor 12 is fixedly installed at the bottom of the left side wall of the lower mold 2, and the output end of the drive motor 12 is fixedly installed together with the rotating rod 11 at the left end. When the drive motor 12 is turned on, the drive output end drives the rotating rod 11 to rotate in the rotating hole 9, so that the rotating rod 11 drives the bidirectional screw 10 to rotate in the rotating hole 9, which can provide a driving effect for the movement of the extrusion block 13.

[0025] like Figure 4As shown, the extrusion block 13 is provided with a set of symmetrical semi-circular shapes, and a slider 14 is fixedly installed on the bottom surface of the extrusion block 13. The slider 14 is slidably installed in the slide 8, and a screw hole 15 is provided on the side wall of the slider 14. The slider 14 is threadedly connected to the bidirectional screw 10 through the screw hole 15. Under the rotation of the bidirectional screw 10, the slider 14 will slide in the slide 8 through the screw hole 15 along the bidirectional screw 10. The symmetrical extrusion blocks 13 will perform opposite movements under the movement of the bottom slider 14.

[0026] like Figure 4 As shown, a set of symmetrical pressure blocks 21 are fixedly installed on the bottom surface of the movable plate 18. The pressure blocks 21 are also semi-circular in shape and inverted. When the pressing block 13 moves, it will press the pressure blocks 21, causing the pressure blocks 21 to push the movable plate 18 upward after being pressed.

[0027] like Figure 4 As shown, a set of symmetrical guide rods 16 are fixedly installed on the left and right sides of the interior of the movable cavity 7, and a compression spring 17 is fitted on the outside of the guide rods 16. The top of the compression spring 17 is fixedly installed on the top surface of the interior of the movable cavity 7. Guide holes 19 are opened on the left and right sides of the top surface of the movable plate 18, and the movable plate 18 is movably installed together with the guide rods 16 through the guide holes 19. The bottom end of the compression spring 17 is fixedly installed on the top surface of the movable plate 18. An ejector rod 20 corresponding to the ejector hole 6 is also fixedly installed on the top surface of the movable plate 18, and the ejector rod 20 is inserted into the ejector hole 6. After the movable plate 18 is pushed, it will move upward along the guide rod 16 through the guide hole 19 and force the compression spring 17 to retract, so that the ejector rod 20 installed on the top surface of the movable plate 18 enters the mold cavity 4 through the ejector hole 6. In this process, the crossbeam connecting plate formed in the mold cavity 4 is ejected from the mold cavity 4 to achieve the purpose of rapid ejection and demolding.

[0028] It should be noted that this utility model is a stamping die for producing a crossbeam connecting plate. After the crossbeam connecting plate is stamped and formed by the die 3 on the bottom surface of the upper die 1 within the die 3 on the top surface of the lower die 2, and after the upper die 1 completes the die opening operation on the top surface of the lower die 2, the drive motor 12 installed at the bottom of the left side wall of the lower die 2 is activated. The drive motor 12 drives the rotating rod 11 to rotate within the rotating hole 9. The rotating rod 11 drives the bidirectional screw 10 to rotate within the sliding port 8, resulting in symmetrical extrusion from left to right. Block 13 moves in opposite directions along the bidirectional screw 10 via the screw holes 15 on the side wall of the slider 14 mounted on the bottom surface. The slider 14 slides within the sliding opening 8. As the semi-circular extrusion block 13 moves outward, it presses against the inverted semi-circular pressure blocks 21 on the left and right sides of the bottom surface of the movable plate 18, which are corresponding to the extrusion block 13. After being pressed, the pressure blocks 21 push the movable plate 18 upward. The movable plate 18 then moves along the guide hole 19 on the top surface. The guide rod 16 installed inside cavity 7 moves, forcing the compression spring 17 fitted outside the guide rod 16 to retract. Simultaneously, the ejector rod 20 installed on the top surface of the movable plate 18 enters the interior of the mold cavity 4 through the ejector hole 6, ejecting the formed crossbeam connecting plate from inside the mold cavity 4. This facilitates rapid ejection and demolding of the formed crossbeam connecting plate from the mold cavity 4, giving the stamping die a rapid demolding function and thus improving production efficiency. After demolding, the drive motor 1 is restarted. 2. The drive output end drives the bidirectional screw 10 to rotate through the rotating rod 11, so that the symmetrical extrusion block 13 moves relative to the slider 14, so that the extrusion block 13 no longer extrudes the pressure block 21, the compression spring 17 performs an elastic recovery and extension operation, and pushes the movable plate 18 so that the movable plate 18 moves downward through the guide hole 19 along the guide rod 16, so that the ejector rod 20 re-enters the ejector hole 6 under the drive of the movable plate 18, in preparation for the next ejection and demolding of the crossbeam connecting plate after molding in the mold cavity 4.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
