Description

Technical Field

[0001] The utility model relates to mold technology, in particular to an automatic punching mold. Background Art

[0002] In order to meet the automatic punching rhythm, automatic punching equipment has high requirements for part unloading. The existing unloading method of punching molds is generally: a stripper plate that imitates the unloading part is set in the mold core, and a hydraulic ejector rod is set at the center of the stripper plate. When the upper and lower molds are separated, the thrust of the ejector rod automatically pushes the stripper plate out of the mold core, thereby unloading the product from the automatic punching die edge to the automatic receiving tray. However, when the size of the unloading part is large, the stripper plate also needs to be enlarged, resulting in uneven force on the stripper plate when a single hydraulic ejector ejects the stripper plate, which is very likely to be offset in position, causing the product to be stuck in the upper mold edge, causing an alarm to occur during the fully automatic production process and unable to operate normally.
