A ejection and demoulding mechanism applied to stamping dies

Abstract

The invention provides an ejection demoulding mechanism applied to a stamping die, relates to the field of die design, and solves the problems that an existing ejection demoulding mechanism can only be applied to iron or parts with high hardness, parts are prone to deforming when soft parts are ejected, and the ejection force cannot be quickly adjusted according to the adhesive force of the parts.The ejection demoulding mechanism applied to the stamping die comprises a punch and a pressing block; and the top end face of the punch is fixedly connected with a support frame through a bolt. Sincea gas outlet channel is communicated with a compressed gas cylinder through a pipeline, and the gas outlet channel is composed of an annular channel and six cylindrical channels, gas can be simultaneously discharged through the six cylindrical channels after entering the annular channel, the gas can make uniform contact with a part, and the phenomenon of demolding failure caused by local stress of the part is prevented. Compared with the prior art, when soft parts are demoulded inconveniently through a push rod structure, demoulding can be achieved by compressed gas.

Description

technical field [0001] The invention belongs to the technical field of die design, and more specifically relates to an ejection and demoulding mechanism applied to stamping dies. Background technique [0002] During the stamping process, due to the shape of the parts and other reasons, after the stamping is completed, the parts are likely to continue to stick to the punch due to the clamping force and other factors, which affects the continuous stamping. The part is released from the mold. [0003] For example, the application number: CN201611024806.X, the invention discloses a secondary ejector stripping mechanism, the ejection unit includes an upper ejector plate and a lower ejector plate, the secondary ejection stripping mechanism also includes a guide element, The ejector unit is movable; the ejector unit also includes a locking element and a slider, the locking element is movably connected with the upper ejector plate, and the locking element is connected with the lowe...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides an ejection and demoulding mechanism applied to stamping dies to solve the existing problem of poor practicability. Although the above-mentioned application can realize secondary ejection, it can only be applied to Iron or parts with higher hardness are used, and the parts are easily deformed when ejecting softer parts; moreover, the adjustability is low, and the above-mentioned application structure is fixed, so it cannot be used according to the attachment of the parts. The problem of realizing the rapid adjustment of the ejection force by focusing on the size of the force
