Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die with an auxiliary demoulding function. Background Art

[0002] Stamping die is a special process equipment used to process materials into parts in cold stamping process, which is called cold stamping die. Stamping is a pressure processing method that uses a die installed on a press (stamping machine) to apply pressure to the material at room temperature to make it separate or plastically deform, thereby obtaining the required parts. According to the processing method of the product, the die can be divided into five categories: punching die, bending die, drawing die, forming die and compression die; Punching die: It completes the work by shearing action. Common forms include shearing die, blanking die, punching die, trimming die, edge straightening die, hole punching die and punching die; Bending die: It bends the flat blank into an angled shape, depending on the part. There are many different types of dies depending on the shape, precision, and production volume, such as ordinary bending dies, cam bending dies, curling dies, arc bending dies, bending and seam punching dies, and twisting dies. Drawing dies are used to make flat blanks into seamless containers with bottoms. Forming dies use various local deformation methods to change the shape of blanks. They include convex forming dies, curling forming dies, necking forming dies, hole and flange forming dies, and round edge forming dies. Compression dies use strong pressure to make the metal blank flow and deform into the desired shape. They include extrusion dies, embossing dies, stamping dies, and end pressure dies. With the development of society, stamping dies are used when stamping parts need to be stamped.

[0003] When a worker needs to perform stamping processing on a workpiece, the worker places the workpiece on a stamping die, and the stamping die stamps and forms the workpiece. After the workpiece is stamped and formed, the worker is traditionally required to manually unload the formed workpiece, which results in low unloading efficiency and poor safety. In addition, the worker will be affected by the smooth surface of the material during the unloading process, causing the worker to slip easily when demolding the formed workpiece, thereby reducing the worker's work efficiency.

[0004] In order to overcome the problem of manual demolding and blanking, among the existing patents, the Chinese patent document with application number 202322026250.X discloses a demolding structure for a metal stamping mold, which relates to the field of demolding technology for stamping molds, including a processing table, a mounting groove is provided on the top of the processing table, a lower mold and a stripping plate are installed inside the mounting groove, a limiting hole is provided on the top of the stripping plate, the lower mold passes through the limiting hole, the stripping plate is movably installed on the outer wall of the lower mold, through holes are symmetrically installed inside the mounting groove, fixing rods are symmetrically installed at the bottom of the stripping plate, and a ball head is installed at the bottom of the fixing rod. The demoulding plate in this patent document moves upward under the action of the electric telescopic rod, and lifts up the stamped metal parts attached to the surface of the mold during the movement, thereby completing the demoulding of the stamped metal parts. At the same time, the metal parts are pushed down in cooperation with the electric push rod, which can avoid the need for manual removal and reduce safety hazards. However, this patent document requires the cooperation of two driving sources, the electric telescopic rod and the electric push rod, to achieve the demoulding and unloading of the metal parts. The number of driving sources is large and the cost is high. Moreover, when the electric telescopic rod lifts up the metal parts, it is easy to cause damage to the metal parts, which is not conducive to ensuring the quality of the workpiece.

[0005] Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

[0022] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0023] like Figures 1 to 5 As shown, the utility model provides a stamping die with auxiliary demoulding function, which includes a concave template 1, a lower die base 2, a lower die plate 3 arranged on the top surface of the lower die base 2, an upper die base 4 arranged above the lower die plate 3, an upper die plate 5 arranged on the bottom surface of the upper die base 4, a support platform 6 arranged on the top surface of the upper die plate 5, a punch 7 installed on the upper die plate 5 and a demoulding drive mechanism 8 installed on the lower die base 2. The upper die base 4 is connected to the lower die base 2 by a guide rod 9 for lifting and sliding. The concave template 1 is provided with a V-shaped cavity 10. The punch The head 7 is concavely and convexly matched with the V-shaped cavity 10, a cavity 11 is provided in the middle of the support platform 6, a rotating cavity 12 is provided on the top surface of the lower template 3, and a rotating block 13 is provided at one end of the concave template 1. The rotating block 13 is located at the rotating cavity 12, and the rotating block 13 is rotatably connected to the inner wall of the rotating cavity 12. The cavity 11 is used to accommodate the concave template 1, and the demoulding drive mechanism 8 is used to drive the concave template 1 to rotate upward out of the cavity 11 or downward into the cavity 11; when the concave template 1 is located in the cavity 11, the top surface of the concave template 1 is flush with the top surface of the support platform 6.

[0024] In actual application, at the beginning, the concave plate 1 is located in the cavity 11, and the top surface of the concave plate 1 is flush with the top surface of the support table 6. The flat workpiece is placed on the support table 6 and the concave plate 1 or the flat workpiece is placed on the concave plate 1. Then the punching machine drives the upper die base 4 to move downward along the guide rod 9 until the punch 7 punches the flat workpiece into the V-shaped cavity 10 of the concave plate 1 to stamp the flat workpiece into a V-shaped workpiece. Then the punching machine drives the upper die base 4 to move upward along the guide rod 9 so that the punch 7 is separated from the X-shaped workpiece, and then the demolding drive mechanism 8 drives the end of the concave plate 1 away from the rotating block 13 upward. At this time, the rotating block 13 rotates in the rotating cavity 12, causing the concave plate 1 to rotate upward around the rotating axis of the rotating block 13 and the lower plate 3. The upward rotating concave plate 1 will gradually tilt until the V-shaped workpiece on the concave plate 1 slides out of the V-shaped cavity 10, thereby realizing automatic demolding and unloading of the V-shaped workpiece; after the V-shaped workpiece is unloaded, the demolding drive mechanism 8 drives the concave plate 1 to reset so that the next workpiece can be stamped and formed. The utility model has a simple structure and can realize automatic demolding and unloading of stamped workpieces, improving the efficiency and safety of demolding. It will not damage the formed workpiece during demolding, thereby ensuring the quality of the formed workpiece.

[0025] In this embodiment, the lower template 3 is connected from top to bottom with a push groove 14 and a slide groove 15, the push groove 14 is connected to the cavity 11, and the demoulding drive mechanism 8 includes a translation drive module 16 installed on the lower mold base 2, a slider 17 connected to the translation end of the translation drive module 16 and slidingly connected to the slide groove 15, an articulated seat 18 provided on the bottom surface of the other end of the concave template 1, and a connecting rod 19 respectively hinged to the articulated seat 18 and the slider 17, and the connecting rod 19 is located in the push groove 14; specifically, the translation drive module 16 can adopt a cylinder or a linear motor. In actual application, when demoulding is required, the translation drive module 16 drives the slider 17 to move backward along the slide groove 15, and the slider 17 moving backward drives the connecting rod 19 to move forward, and the connecting rod 19 moving forward pushes the hinge seat 18 and the end of the concave plate 1 away from the rotating block 13 to rotate upward until the V-shaped workpiece on the concave plate 1 slides out of the V-shaped cavity 10, so as to realize automatic demoulding and unloading; after demoulding is completed, the translation drive module 16 drives the slider 17 to move forward along the slide groove 15, and the slider 17 moving forward drives the connecting rod 19 to move in the opposite direction, and the connecting rod 19 moving in the opposite direction pulls the hinge seat 18 and the end of the concave plate 1 away from the rotating block 13 to rotate downward until the concave plate 1 is accommodated in the cavity 11, so as to realize the resetting of the concave plate 1.

[0026] In this embodiment, the sidewalls of the chute 15 are recessed with a limiting guide groove 20, and the sidewalls of the slider 17 are convexly provided with a limiting guide block 21 that slidably engages with the limiting guide groove 20. As the slider 17 moves along the chute 15, the limiting guide block 21 slides along the limiting guide groove 20. The limiting guide groove 20 guides and limits the limiting guide block 21, thereby improving the stability of the slider 17 and preventing the slider 17 from easily separating from or loosening the lower template 3.

[0027] In this embodiment, a demolding anti-throw mechanism 22 is installed at the end of the die plate 1 away from the rotating block 13. This mechanism 22 is used to prevent the formed workpiece (V-shaped workpiece) from being thrown during demolding. When demolding the V-shaped workpiece within the V-shaped cavity 10 of the die plate 1, the demolding anti-throw mechanism 22 blocks the V-shaped workpiece in the V-shaped cavity 10 to prevent it from being thrown off the die plate 1. This ensures that the V-shaped workpiece slides along the V-shaped cavity 10 for demolding and discharge, thereby improving the stability of the demolding process.

[0028] In this embodiment, the demolding anti-throw mechanism 22 includes a mounting base 23 mounted on an end of the concave plate 1 away from the rotating block 13, an anti-throw member 24 rotatably connected to the mounting base 23, and a rotary actuator 25 mounted on the mounting base 23 and configured to rotate the anti-throw member 24. The rotary actuator 25 is configured to drive the anti-throw member 24 into or out of the V-shaped cavity 10. Specifically, the rotary actuator 25 may be a motor.

[0029] In actual application, before the demolding drive mechanism 8 drives the concave plate 1 to rotate upward, the rotation driver 25 drives the anti-throwing member 24 to rotate into the V-shaped cavity 10 and blocks the V-shaped workpiece in the V-shaped cavity 10 to prevent the V-shaped workpiece from being thrown out of the V-shaped cavity 10 when the concave plate 1 rotates upward quickly.

[0030] In this embodiment, the anti-throw member 24 includes an anti-throw bar and an adapter block perpendicularly connected to one end of the anti-throw bar. The adapter block is rotatably connected to the mounting base 23, and the adapter block is drivingly connected to the rotating end of the rotation driver 25. When the anti-throw bar rotates into the V-shaped cavity 10, it blocks the V-shaped workpiece. When the punch 7 is stamping the workpiece on the die plate 1, the anti-throw bar is outside the V-shaped cavity 10, so that the anti-throw member 24 does not hinder the punch 7 from stamping the workpiece.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
