Description

Technical Field

[0001] This utility model belongs to the field of mechanical mold design technology, specifically relating to a mechanical mold structure for rapid demolding. Background Technology

[0002] Mechanical molds are core equipment used in industrial production to define the shape and size of workpieces. By working with equipment such as presses, they enable raw materials (such as metal sheets) to be plastically deformed or separated into target parts. They are widely used in the automotive, electronics, and construction industries. Among them, stamping mechanical molds rely on the pressure of the press to drive the upper and lower dies to close, thereby realizing the punching, bending, and forming of metal sheets. Workpieces such as the Z-shaped beams of automobile bodies, the Z-shaped supports of light steel structures in buildings, and the Z-shaped brackets inside electronic products all need to be processed and formed by such stamping dies to meet the requirements of structural strength and installation compatibility.

[0003] However, when stamping workpieces with a Z-shaped structure, the bottom die often uses a reset ejection structure with a built-in spring. After stamping, the spring force pushes the top plate to lift the workpiece from the bottom die. However, because the workpiece is tightly attached to the die during stamping, it is easy for the workpiece to get stuck on the die. At this time, the spring ejection can only separate the workpiece from the bottom die. The workpiece stuck on the die still needs to be manually removed, which affects the demolding efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 5As shown, this utility model embodiment provides a mechanical mold structure for rapid demolding, specifically including a mounting base 1, two fixed posts 2 fixedly connected to the mounting base 1, a mounting plate 3 fixedly connected between the two fixed posts 2, an adjusting plate 4 slidably connected between the two fixed posts 2, and a demolding structure 5 provided between the adjusting plate 4 and the mounting plate 3. The demolding structure 5 specifically includes fixed rods 501, two fixed rods 501 fixedly connected to the mounting plate 3, a guide frame 502 fixedly connected between the two fixed rods 501, a push plate 503 fixedly connected to the guide frame 502, a drive plate 505 fixedly connected to the push plate 503, a connecting rod 504 fixedly connected to the adjusting plate 4, a drive shaft 510 rotatably connected between the two connecting rods 504, and a sloping groove 506 and an inlet 507 provided on the drive plate 505, with the drive shaft 510 and the sloping groove 506 in rolling engagement. A guide rod 508 is fixedly connected to the guide frame 502. The push plate 503 is slidably connected to the guide rod 508. After stamping, the drive component 9 drives the adjusting plate 4 to reset upward. The connecting rod 504 on the adjusting plate 4 synchronously drives the drive shaft 510 to rise. The drive shaft 510 enters the inclined groove 506 of the drive plate 505 from the inlet 507 and rolls along the inclined groove 506, forcing the drive plate 505 to drive the push plate 503 to slide along the guide rod 508 on the guide frame 502. The push plate 503 applies a pushing force to the formed workpiece. To aid demolding, a tension spring 509 is fixedly connected between the push plate 503 and the guide frame 502. A pressure mold 8 is installed on the adjusting plate 4, and a bottom mold 10 is installed on the mounting base 1. After the workpiece is placed, the drive component 9 (preferably a hydraulic rod) on the mounting plate 3 is activated. The telescopic end of the drive component 9 drives the adjusting plate 4 to slide downward along the fixed column 2, so that the pressure mold 8 on the adjusting plate 4 cooperates with the bottom mold 10 on the mounting base 1 to complete the stamping and forming of the workpiece. The drive component 9 is installed on the mounting plate 3, and the adjusting plate 4 is driven by the drive component 9.

[0020] Please see Figures 1 to 5 As shown, the bottom mold 10 is provided with a positioning structure 6, which specifically includes a fixed frame 601. The fixed frame 601 is fixedly connected to the bottom mold 10, and a slider 602 is slidably connected to the fixed frame 601. A positioning rod 603 is fixedly connected to the slider 602, and an inclined surface 604 is provided on the positioning rod 603. A lead screw 606 is rotatably connected to the fixed frame 601. The slider 602 is threadedly connected to the lead screw 606, and the threads at both ends of the lead screw 606 are in opposite directions. First, the lead screw 606 is rotated by rotating the rotating block 607. The screw 606 has opposite threads at both ends, which drives the two sliders 602 to slide synchronously in opposite directions on the fixed frame 601. This, in turn, moves the positioning rod 603 to accommodate workpieces of different sizes. The inclined surface 604 on the positioning rod 603 facilitates the smooth placement of the workpiece and provides initial guidance. Together with the four positioning pins 605 on the bottom mold 10, it can quickly and accurately position the workpiece, effectively improving positioning efficiency. A rotating block 607 is fixedly connected to the screw 606, and four positioning pins 605 are fixedly connected to the bottom mold 10.

[0021] Please see Figures 1 to 5 As shown, the bottom mold 10 is provided with a lifting structure 7, which specifically includes a top plate 701. The top plate 701 is slidably connected to the bottom mold 10, and a guide shaft 702 is fixedly connected to the top plate 701. The guide shaft 702 is slidably connected to the bottom mold 10. The setting of the guide shaft 702 makes the movement of the top plate 701 more stable. The compressed spring 704 will push the top plate 701 to lift the workpiece upward, so that the workpiece is quickly separated from the bottom mold 10. A connecting ring 703 is fixedly connected to the guide shaft 702. The connecting ring 703 abuts against the bottom mold 10. A spring 704 is fixedly connected between the top plate 701 and the bottom mold 10.

[0022] In use, this invention first rotates the rotating block 607 to drive the lead screw 606 to rotate. Since the threads at both ends of the lead screw 606 are opposite, they drive the two sliders 602 to slide synchronously in opposite directions on the fixed frame 601, thereby driving the positioning rod 603 to move to accommodate workpieces of different sizes. The inclined surface 604 on the positioning rod 603 facilitates the smooth placement of the workpiece and provides initial guidance. In conjunction with the four positioning posts 605 on the bottom mold 10, the workpiece can be quickly and accurately positioned, effectively improving positioning efficiency. After the workpiece is placed, the driving component 9 (preferably a hydraulic rod) on the mounting plate 3 is activated. The telescopic end of the driving component 9 drives the adjusting plate 4 to slide downward along the fixed post 2, so that the pressure die 8 on the adjusting plate 4 cooperates with the bottom mold 10 on the mounting base 1 to complete the stamping and forming of the workpiece. During this process, the workpiece will press against the top plate 701, causing the top plate 701 to drive the guide shaft 702 to slide downward along the bottom mold 10 and press. After stamping, the drive component 9 drives the adjusting plate 4 to return to its original position. The connecting rod 504 on the adjusting plate 4 simultaneously drives the drive shaft 510 to rise. The drive shaft 510 enters the inclined groove 506 of the drive plate 505 from the inlet 507 and rolls along the inclined groove 506, forcing the drive plate 505 to drive the push plate 503 to slide along the guide rod 508 on the guide frame 502. The push plate 503 applies a pushing force to the formed workpiece to assist in demolding. The tension spring 509 is stretched when the push plate 503 moves. After the drive shaft 510 leaves the inclined groove 506, the tension spring 509 can pull the push plate 503 to return to its original position quickly for the next operation. At the same time, the compressed spring 704 pushes the top plate 701 to lift the workpiece upward, so that the workpiece is quickly separated from the bottom mold 10. By applying a pushing force to the formed workpiece through the push plate 503 to assist in demolding, the workpiece can be quickly demolded from the mold 8, avoiding the workpiece from getting stuck on the mold 8. Manual demolding is not required, thus improving demolding efficiency.
