Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die positioning structure. Background Art

[0002] Stamping dies are a special process equipment used to process metal or non-metal into parts during cold stamping. Common stamping dies often include an upper die and a lower die, which are guided by built-in guide pillars. At the same time, bayonet and clamping columns are designed on the edge of the lower die to improve positioning accuracy. However, since the upper and lower dies of the mold need to be fixed on the plane and the punch head respectively, directly fixing the mold often leads to horizontal errors, which in turn causes friction and wear of positioning structures such as guide pillars, guide sleeves, bayonet blocks, etc., reducing mold accuracy and service life.

[0007] As a preferred technical solution of the utility model, the outer wall of the pillar is smooth, and the lifting slide plate can slide freely on the pillar.

[0008] The beneficial effects of the utility model are as follows: the utility model clamps the lower mold through the adjusting screw and the pressure plate, and fixes the upper mold on the mounting slide, guides it through the pillar, and adjusts the position of the mounting slide according to the buckling situation of the upper and lower molds, thereby reducing the dimensional error caused by mechanical fixation, avoiding friction and wear of the guide pillars, guide sleeves, and bayonet blocks, greatly increasing the practical life of the mold, and is also suitable for molds of various sizes.

DETAILED DESCRIPTION

[0014] Example 1

[0015] like Figures 1 to 3As shown, the utility model discloses a stamping die positioning structure, including a bottom plate 1, a vertical plate 2, a reinforcing plate 3, an adjusting screw 4, an adjusting screw locking nut 5, a pressure plate 6, a pillar 7, a pillar connecting plate 8, a lifting slide plate 9, an installation slide plate 10, a connecting screw 11, a connecting screw locking nut 12, a gasket 13, and a die locking screw 14; the vertical plates 2 are installed on the four edges of the upper surface of the bottom plate 1, and two reinforcing plates 3 are installed between each vertical plate 2 and the bottom plate 1; two screw holes are opened in the center of the vertical plate 2, and the adjusting screw The rod 4 passes through the screw hole and is fixed with the adjusting screw locking nut 5, and a pressure plate 6 is installed at the end of the adjusting screw 4; the pillar 7 is installed at the four corners of the upper surface of the bottom plate 1, and a pillar connecting plate 8 is installed at its top; the lifting slide 9 is installed on the left and right pillars 7, and a long hole is opened in the center; the installation slide 10 has a long hole in the center, and both the left and right ends are equipped with connecting screws 11 and connecting screw locking nuts 12 fixed on the lower side of the lifting slide 9; the mold locking screw 14 is equipped with a gasket and passes through the long hole in the center of the installation slide 10. The outer wall of the pillar 7 is smooth, and the lifting slide 9 can slide freely on the pillar 7. The pillar 7 ensures the vertical sliding of the lifting slide 8 and plays a guiding role; the length of the adjusting screw 4 is not less than half of the length of the short side of the bottom plate 1; the pressure plate 6 is a rubber disk, and its diameter is not less than half of the height of the vertical plate 2, which is convenient for pressing the lower mold from four sides by rotating the adjusting screw 4, and is more convenient for installing molds of different sizes.
