A stamping die and its waste material ejection mechanism

Abstract

The invention discloses a stamping mold and a waste ejection mechanism thereof. The waste ejection mechanism comprises a cylinder of which a fixed end is arranged on a lower die holder, wherein a telescopic end of the cylinder is provided with an ejection plate through a rotating shaft in a rotating manner; the rotating shaft is arranged perpendicular to the axial direction of the cylinder; when the cylinder is at an extension limit position, the ejection plate rotates around the rotating shaft to a state back on to a mold body; one end of the ejection plate is provided with a guide plate which is provided with a guide groove; the fixed end is provided with a guide block which is in slide guide fit with the guide groove; the plane where the guide stroke of the guide groove is positioned is parallel to the axial direction of the cylinder and perpendicular to the axial direction of the rotating shaft; the guide groove comprises an upper guide groove and a lower guide groove which is communicated with the upper guide groove; the slide guide direction of the upper guide groove is parallel to the axial direction of the cylinder; the lower guide groove and the upper guide groove are at a preset angle; the lower guide groove gets away from the mold body gradually in the extension direction away from the upper guide groove. Thus, ejection stroke and discharge direction of waste can be excellently controlled through the arrangement of the guide structure.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a waste material ejection mechanism for stamping dies. The present invention also relates to a stamping die comprising the above-mentioned waste material ejection mechanism. Background technique [0002] Stamping dies are widely used in automobile development and production, especially for the processing of automobile panels. The stamping process plan needs to determine drawing, trimming, punching, flanging, shaping, etc. according to the product structure shape and technical requirements. The processing sequence of each process and the specific content of each process should also consider the requirements of convenient stamping operation, safety, reasonable mold structure, and smooth discharge of workpieces and waste materials. In the processing of automobile panels, the trimming process requires that the waste generated after trimming can slide off the mold smoothly, and try to a...

Problems solved by technology

[0005] However, the above-mentioned waste material ejection mechanism hooks the waste material by the waste material hook installed on the upper die, and the waste material is brought up by the upper die to move upwards to realize the waste material discharge, but the movement condition of the waste material after being lifted by the waste material hook is unstable, and the direction of motion Out of control, the waste may fall into the mold cavity, or fail to fall into the waste chute, resulting in the failure to be discharged out of the mold smoothly. The reliability of waste discharge is poor, and manual cleaning is still required, which wastes manpower and material resources and affects the mold. Processing takt
