Demoulding device for thin-wall deep-drawing part process

Abstract

The invention relates to a demoulding device for a thin-wall deep-drawing part process. The demoulding device mainly comprises a discharging ring (2), a material guiding barrel (3) and a thread check ring (4) which are sleeved sequentially from top to bottom, wherein a rubber ring (6) is hooped in a U-shaped slot of the discharging ring (2) for fixing; a spring (7) is arranged on the thread check ring (4) and is used for supporting the material guiding barrel (3); a taper hole seat (1) is used for sleeving the components; and a thread is matched with the thread check ring (4). The demoulding device is characterized in that: a step-shaped structure (13) is arranged at the position, which is close to the upper port, on the inner wall of the discharging ring (2) to form an inner flange (14) and an auxiliary support surface (15). Due to the adoption of the unique design of spliced discharging blocks and the inner flange, the demoulding device can obviously reduce the demoulding difficulty of 500ml-steel cans and can effectively prevent the openings of the cans from being pressed and destabilized in the demoulding process.

Description

technical field [0001] The invention relates to a demoulding device, which is suitable for the production process of thin-walled deep-drawn parts, especially for the processing process of pop cans. Background technique [0002] Existing demoulding devices for deep-drawn parts are mainly can ejectors. The can ejector adopts shape guidance to force cans to be ejected. For parts with large wall thickness, this multi-claw can ejector is very helpful for demoulding. However, the wall thickness of the can body is only about 0.07mm, and the large pressure during demoulding will cause the can mouth The parts are unstable and wrinkled, which affects the product quality. [0003] For the production process of thin-walled deep-drawn parts, the problem of pot-shaped demoulding after deep-drawing or thinning-drawing has always been a technical difficulty in production. There are two main reasons for the can-shaped demoulding problem: one is due to the unique shape of the can. For two...

Problems solved by technology

However, due to the shape of the die for thinning and deep drawing and the limitation of the deformation process, the mouth of the tank shape will be held inwardly on the punch after the blank is thinned and deep drawn, which increases the difficulty of demoulding.

The second is that due to the thin wall of the can and the shape characteristics of the height of the can, the possibility of the can becoming unstable and wrinkled during demoulding increases
