AI Technical Summary
Technical Problem
The first sound insulation board and the second sound insulation board of the existing automotive stamping part mold are not closed, and noise will be transmitted from the gap, making it difficult to achieve the ideal noise reduction effect.
Method used
An automobile stamping mold is designed, and a multi-layer sound insulation structure is formed by setting a first sound-retardant panel group, a second sound-retardant panel group and a sound-retardant panel mechanism to ensure that noise is effectively blocked and absorbed.
Benefits of technology
Effectively block the noise generated during stamping, reduces the damage to the health of the noise to the staff, and solves the problem of noise coming out through the gap in the prior art.

Abstract
The invention discloses an automobile stamping part die, relates to the technical field of stamping part dies for automobile production, and aims to solve the problems that the space between a first sound insulation plate and a second sound insulation plate of an automobile stamping part die is not closed, noise can be transmitted out from a gap, and the closer to resonance in a smaller gap, the stronger vibration is, the larger the sound is, and the noise is poor. A fixed mold is arranged below a movable mold, an upper sound insulation structure is installed on the outer side of the lower end of the movable mold, a lower sound insulation structure is installed on the outer side of the upper end of the fixed mold, and falling part cleaning mechanisms are arranged in front of and behind the movable mold. The front side and the rear side of the lower portion of the fixing frame of the upper sound insulation structure are symmetrically provided with first sound blocking plate sets, and the front side and the rear side of the upper portion of the fixing frame of the lower sound insulation structure are symmetrically provided with second sound blocking plate sets. And sound insulation plate mechanisms are symmetrically arranged on the left and right sides of the lower end of the upper sound insulation structure and the left and right sides of the upper end of the lower sound insulation structure.
