Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] Please refer to Figure 1 to Figure 4 , the embodiment of the present invention provides a mold backing plate, which is used to assist the multi-station press to install the mold (not shown in the figure). The multi-station press includes a press table (not shown). The die backing plate includes an upper die backing plate 1 and a lower die backing plate 3 used in conjunction with the upper die backing plate 1 .

[0021] The backing plate 1 of the upper mold is provided with a locking bolt hole 11 for easy connection with the mold (not shown). A plurality of U-shaped grooves 13 are respectively spaced apart from two opposite edges of the upper mold backing plate 1 , and hanging lugs 15 protrude from the two opposite ends of the...

Abstract

The invention discloses a die base plate which belongs to the technical field of stamping dies. The die base plate is used for assisting a multi-station press in die filling, and comprises an upper die base plate and a lower die base plate which are detachably fixed on a die, wherein the lower die base plate is provided with an ejector rod through hole through which an ejector rod of the multi-station press penetrates. When the production of the multi-station press is finished, the upper die base plate and the lower die base plate of the die base plate can be detached and can be conveniently applied to other dies. Therefore, the upper die base plate and the lower die base plate can be repeatedly used, the universality of the die base plate is high, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a die backing plate. Background technique [0002] With the rapid development of domestic and foreign automobile industries and the continuous adoption of new technologies, more and more automobile factories and stamping factories use multi-station presses to improve production efficiency and output. [0003] The maximum mold height of conventionally used multi-station presses is 1145mm, and the minimum mold height is 790mm (that is, the adjustment amount of mold height is 355mm). The normally designed molds for small and medium-sized structural parts are generally designed with a closed height of 400-750 mm. In order to meet the needs of multi-station presses, a set of backing plates is generally required for each type of workpiece to meet the needs of multi-station presses. Die height requirements. However, a set of corresponding backing plates needs to be developed for...
