Automatic die

Abstract

The invention discloses an automatic die, which comprises a lower die (2); the lower die (2) is symmetrically provided with two motion blocks (4); the two motion blocks (4) can respectively rotate by taking a shaft (6) as the center; the two motion blocks (4) are respectively provided with a die cavity (7) used for containing a workpiece; the die cavities (7) can move to the side face of the lower die (2). The automatic die is characterized in that a driven wheel (14) sheathes each shaft (6); each driven wheel (14) is connected with a driving wheel (18), arranged on the lower die (2), through a corresponding driving belt (16); the driving wheel (18) is in drive connection with a motor. The automatic die disclosed by the invention is higher in service safety.

Description

technical field [0001] The invention relates to an automatic mold, which is particularly suitable for stamping and forming of hardware products. Background technique [0002] At present, the punching die is generally composed of a punch and a die, and can also be composed of multiple punches and multiple dies, but only one punching process can be completed in one stroke of the punching machine. When the shape of the part is complex, it needs to be composed of more than one single-engineering punching die to produce a qualified product. This kind of mold is not only insufficient in stability, but also wastes manpower cost and mechanical cost. [0003] The Chinese patent authorization announcement number is CN203900258U, and the utility model patent with the authorization announcement date on October 29, 2014 discloses a continuous mold for connecting cushion covers, including an upper mold base and a lower mold base, and is arranged on the upper mold base and the lower mold....

AI Technical Summary

Problems solved by technology

Although the utility model can produce the connection pad cover at a faster production speed, it can be seen that it can effectively reduce labor costs and mechanical costs, reduce the reject rate of the product, and it can be seen that it has high stability. However, it has been found in long-term use that due to The mold with the above structure is not equipped with any safety mechanism. After the mold is opened, especially when changing the material, if the upper mold suddenly falls due to a mechanical failure, it will easily cause a safety hazard.
