Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a die holder structure. Background Art

[0002] The lower die is the lower half of the entire stamping die, that is, the stamping die part installed on the workbench surface of the press. The lower die holder is the part of the lower die that contacts the workbench surface of the press, generally a plate part, which is directly fixed on the press table or the backing plate.

[0003] Patent authorization announcement number CN213410038U discloses a lower die holder structure for a stamping die. First fixing plates are symmetrically arranged above the seat body, and a connecting plate is connected to one side of the seat body. A second fixing plate is arranged above the first fixing plate, and a splicing mechanism is connected between the first fixing plate and the second fixing plate. One end of a rotating rod is rotatably connected to one side of one of the first fixing plates, and a chute is opened below it. One end of the rotating rod penetrates through the connecting plate and is connected to a hand wheel, and the connecting plate and the rotating rod are connected through a connecting sleeve. The structure of the utility model is simple and convenient for workers to operate. Before the stamping die, it is necessary to first fix the die on the lower die holder. For dies of different sizes, the distance between the two clamping plates can be manually adjusted, which is convenient and fast, and the clamping force is easy to control. If the die is relatively high, the first fixing plate and the second fixing plate can be spliced and used, so that the die can be fixed more stably.

[0004] However, the above technical solution has the following deficiencies: During the process of stamping parts by the stamping die, a large vibration will be generated. The vibration easily causes rotation between the rotating rod and the connecting sleeve, resulting in loosening of the clamping plate, making the lower die holder not firmly fixed, and affecting the use effect of the die in the subsequent process of stamping parts.
