The head of the thimble faces upwards, is positioned on the spring and can move up and down in the thimble groove of the fixed base plate. By adopting the structure, the thimble moves up and down in the thimble groove under the action of the spring force to push the male block.

Preferably, the method comprises the following steps: and a horizontal through groove is formed in the vertical surface of the right-angle side of the male block. By adopting the structure, the characteristic areas on the parts can be avoided fully when the parts are bent and formed.

Preferably, the method comprises the following steps: the diameter of the spring groove is larger than that of the thimble groove. By adopting the structure, the head part of the thimble is limited in the lower die base.

Preferably, the method comprises the following steps: the spring groove, the thimble groove and the center of gravity of the male block are on the same straight line.

Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1, an exploded view of a slide block mechanism of a stamping die convenient for stripping comprises: the device comprises a male block 1, a female block 2, an ejector pin 3, a fixing plate 4, a fixing base plate 5, a lower die holder 6, a spring 7, a fixing bolt 8 and a base bolt 9.

The male block 1 is in an inverted trapezoid shape, an oblique side edge 1a is arranged on the male block, and a horizontal through groove 1b is formed in the vertical surface of the right-angle side of the male block 1.

The female block 2 is provided with an oblique sliding chute 2a which is matched with the oblique side edge 1a of the male block 1. Be equipped with locating hole 2b on female piece 2, fix a position it on fixed plate 4 and link firmly with fixed bolster 5 and die holder 6 simultaneously through fixing bolt 8.

The fixed plate 4 is provided with a straight-edge through hole according to the combined shape of the male block 1 and the female block 2, and the male block is limited by the straight edge on the fixed plate. And a space 4a is reserved along the outer direction of the square edge of the male block and is used for bending and forming the stamping part.

Fig. 2 and 3 show schematic views of a stamping die slide mechanism for facilitating stripping in operation and in return.

Referring to fig. 4, a thimble groove 5a is formed on the fixed backing plate a; the lower die holder 6 is provided with a spring groove 6 a; the spring 7 is placed in the spring groove 6a, and one end of the spring 7 is sleeved on the base bolt 9. The head of the thimble 3 is upward and is positioned on the spring 7, and the thimble 3 can move up and down in the thimble groove 5a of the fixed cushion plate 5 under the action of the spring force to push the male block 1.
