Description

Technical Field

[0001] This utility model belongs to the field of molds, specifically, it relates to a single-acting hydraulic cylinder mold locking structure. Background Technology

[0002] When producing sheet metal using stamping and punching dies, the lower die needs to be changed depending on the type of sheet metal and production requirements. After changing the lower die, it needs to be locked and positioned to ensure that the lower die is fixed in position after the upper and lower dies are pressed together, making it inconvenient to shake or move, thereby improving the processing quality of the sheet metal. Usually, a hydraulic cylinder is used to directly press the lower die, but the hydraulic cylinder needs to be equipped with a hydraulic station, which increases production costs, occupies a lot of space, and is not suitable for small stamping machines.

[0003] To address the aforementioned issues, patent document 110239045A discloses a piston-connecting rod mechanism for a mold-locking cylinder in an injection molding machine. This mechanism includes a mold-locking piston rod, a mold-locking cylinder barrel, a mold-locking piston, a mold-locking nut, and a combined piston clamping ring. The mold-locking piston is inserted into the mold-locking piston rod, with its left side limited by the rod and its right side fixed by a nut on the rod. A groove is provided in the middle of the piston, forming a cavity between the groove and the piston rod to accommodate the combined piston clamping ring. The combined piston clamping ring is placed in the cavity and locks the mold-locking piston to the locking piston rod. However, this mechanism fails to solve the aforementioned problems.
