Abstract

An installing structure of male die loose cores comprises an upper die assembly and a lower die assembly, wherein a knock-out pin fixing base is installed at the bottom of an upper die base through bolts, and a knock-out pin is installed on the knock-out pin fixing base and is fixed on the upper die base through an elastic-ejecting assembly; a first rotary shaft fixing base is installed at one end of a lower die base through a fastening piece and is provided with a first rotary shaft, a connecting rod fixing base is installed on the lower die base and on one side of the first rotary shaft fixing base through a fastening piece, and a second rotary shaft is arranged at the top of the connecting rod fixing base; a female die fixing board is provided with a loose core fixing base, the loose cores are installed at one end of the loose core fixing base, a long circular groove is formed in the other end of the loose core fixing base, and a third rotary shaft is installed in the long circular groove; a first connecting rod is installed between the first rotary shaft and the second rotary shaft, and a second connecting rod is installed between the second rotary shaft and the third rotary shaft. The installing structure of the male die loose cores is reliable and stable in operation.

Description

technical field [0001] The invention relates to a mold device, in particular to a punch core pulling installation structure. Background technique [0002] Many of the products produced by the mold are closed or semi-closed. At this time, effective punch core pulling is required. When the core-pulling stroke is long, the punching machine needs to have a large mold opening stroke and a long-distance unloading stroke. This reduces the stamping times of the mold, the stability and life of the mold production. [0003] Core-pulling molding is used in the mold. Generally, the inclined wedge mounted on the punch fixing plate is hit on the excessive wedge to drive the forming mandrel (that is, the core-pulling) to slide to the working position for work or the inclined wedge is mounted on the unloading. The material board is hit on the excessive wedge to drive the forming mandrel (that is, the core pulling) to slide to the working position for work. If the core pulling distance is...
