Upper die of stamping die and stamping die

Abstract

The invention discloses an upper mold of a punching mold. The upper mold comprises an upper mold seat (11), a material pressing core (16), a plurality of elastic elements (12), a mounting plate (14) and a force transfer rod (15), wherein the elastic elements (12) are mounted on the upper mold seat (11), and the upper mold seat (11) comprises a mounting part located between the elastic elements (12); the mounting plate (14) is movably mounted on the mounting part, two ends of the force transfer rod (15) are respectively fixed together with mounting plate (14) and the material pressing core (16), and the elastic elements (12) are mounted between the inner wall of the upper mold seat (11) and the mounting plate (14). According to the upper mold, the size of the mounting plate can be increased properly, so that an enough mounting space is provided for the elastic elements. The invention further discloses the punching mold comprising the upper mold.

Description

technical field [0001] The invention relates to the technical field of stamping devices, in particular to an upper die of a stamping die. The invention also relates to a stamping die. Background technique [0002] With the rapid development of the automobile industry, the application of stamping dies has become more and more extensive. During the stamping process, the elastic elements installed in the upper die provide sufficient pressing force to prevent the movement of the sheet during the stamping process and cause the plate The problem of lower precision and lower quality of stamping parts. [0003] The currently commonly used stamping die mainly includes an upper mold base 1, a side pin 2, a lower mold base 3, a pressing core 4, a square pad 5, an elastic element 6, a spring guide pin 7 and a guide plate 8. Wherein: the upper mold base 1 is an integral casting structure, the side pin 2 passes through the side wall of the upper mold base 1, and is fixed on the upper mo...

Problems solved by technology

[0004] However, for parts with a smaller product size, the size of the pressing core 4 is also smaller, and the size and quantity of the elastic elements 6 required to be used will not be greatly reduced due to other factors, resulting in the pressing The core 4 cannot provide enough space to install the elastic element 6, resulting in inconvenient installation of the elastic element 6

[0005] In addition, since the pressing core 4 is small, the pressing core 4 cannot provide enough space for the side pin 2, so that the installation of the side pin 2 is also inconvenient
