[0001] This utility model relates to the field of stamping mechanism technology, specifically a multi-directional stamping mechanism for a mold. Background Technology

[0002] The die stamping mechanism is a key part of the stamping die to realize the stamping process. It is mainly used to apply external force to materials such as sheet metal, strip, tube and profile to cause plastic deformation or separation, thereby obtaining workpieces with the required shape and size.

[0003] Currently, multi-directional stamping mechanisms for molds on the market typically use multiple sets of drive components to control multiple sets of stamping dies. In use, the part to be stamped is first placed on the stamping table, and then the front and rear ends of the part are clamped by the clamping plate. Then, the left and right stamping dies are started simultaneously by the controller, and the part is stamped by the stamping dies at both ends at the same time. However, this device has certain defects in daily maintenance, namely, it requires maintenance of multiple sets of drive components, which further increases the cost of spare parts. Therefore, this utility model proposes a multi-directional stamping mechanism for molds to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 4 This utility model provides a technical solution: a multi-directional stamping mechanism for a mold, including a processing table 1, and further including: a return spring 11, disposed at both ends of the processing table 1; a drive assembly 2, which includes a set of cylinders 21 and two sets of sleeves 26, the cylinders 21 and sleeves 26 are both mounted on the upper top plate of the processing table 1, and the output end of the cylinder 21 and the guide post 261 in the sleeve 26 are both connected to the guide plate 22, the lower edge of both ends of the guide plate 22 is equipped with wedges 23, and the lower end of the wedges 23 is provided with oblique openings; a stamping assembly 3, which includes two sets of support seats 31, each of the two sets of support seats 31 is provided with a guide cavity 32, and a stamping block 33 is slidably disposed in the guide cavity 32, the stamping block 33 having an oblique opening corresponding to the wedge 23; and a positioning assembly 4, disposed between the left and right sets of stamping assemblies 3, which functions to place the workpiece to be stamped and to position the workpiece to be stamped.

[0020] Please see Figures 1 to 4 One end of the stamping block 33 is connected to the auxiliary rod 34. One end of the auxiliary rod 34 has a handle ring. The handle ring end passes through the processing table 1 and the collar of the return spring 11, and abuts against the collar provided at one end of the return spring 11. The outer diameter of the auxiliary rod 34 is provided with a thread 35. The auxiliary rod 34 is screwed into the thread cavity of the support seat 31. When it is necessary to replace the stamping block 33, the stamping block 33 can be taken out from the side of the guide cavity 32 by spiraling the auxiliary rod 34.

[0021] Please see Figures 1 to 4 The positioning component 4 includes a positioning platform 41, with a rectangular cavity in the middle. A positive and negative threaded rod 42 is provided in the rectangular cavity, and the two ends of the positive and negative threaded rod 42 are respectively connected to the clamping plate 43.

[0022] In actual use, the part to be stamped is first placed on the positioning table 41, and then the positive and negative threaded rods 42 are turned to drive the clamping plates 43 at both ends to position the front and rear ends of the stamped part. After positioning, the cylinder 21 in the drive assembly 2 is started. The output end of the cylinder 21 extends downward, driving the guide plate 22 to move downward. Since the guide plate 22 is connected to the guide post 261 in the sleeve 26, the guide post 261 will move downward in the vertical direction in the sleeve 26 to ensure the stability of the movement of the guide plate 22. At the same time, the wedge block 23 also moves downward with the guide plate 22. As the wedge block 23 moves downward, the oblique opening at the lower end of the wedge block 23 interacts with the corresponding oblique opening on the stamping block 33. Due to the oblique opening design of the wedge block 23, a horizontal component force is generated on the stamping block 33. Under the action of the cylinder 21, the stamping block 33 moves horizontally in the guide cavity 32 of the support seat 31. At the same time, the slider 24 moves vertically downward in the guide groove 25 on the inner end face of the processing table 1, providing guidance and support for the movement of the wedge block 23. When the stamping blocks 33 at both ends move towards the middle, the workpiece to be stamped that has been positioned on the positioning table 41 can be stamped. After the stamping is completed, the cylinder 21 moves upward. At this time, since the horizontal force of the wedge block 23 on the stamping block 33 is lost, the stamping block 33 begins to move away from the workpiece to be stamped under the elastic force of the return spring 11. The stamping block 33 drives the auxiliary rod 34 to move together. The handle ring end of the auxiliary rod 34 moves along the collar of the return spring 11, and finally the stamping block 33 returns to the initial position.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
