A slidable lower mold base device

Abstract

The invention discloses a slidable lower mold base device, which comprises a cuboid lower mold base, a cuboid-shaped groove is arranged in the center of the upper part of the lower mold base, and a sliding plate sliding left and right is arranged in the cuboid-shaped groove , the surface of the sliding plate is provided with a first mold jacket and a second mold jacket arranged side by side, a stamping die is placed inside the first mold jacket and the second mold jacket; a gap is provided on the right side of the cuboid groove, and The right side of the mold base is provided with a first driving mechanism and a second driving mechanism arranged side by side; the bottom surface of the left part of the lower mold base is provided with two vertical through holes arranged side by side, and the two through holes are respectively A first ejector rod and a second ejector rod are provided. The invention relies on the cylinder to remove the sliding plate with the multi-station mold from the bottom of the slider to carry out the loading and unloading process. At the same time, a hydraulic cylinder jacking device is installed under the mold base, which can realize fast, safe and high-efficiency stamping production.

Description

technical field [0001] The invention relates to a mold equipment for metal stamping, in particular to a slidable lower mold base device. Background technique [0002] All kinds of existing cold or hot forming presses are composed of fuselage, frame, slider for fixing the upper mold and base for fixing the lower mold, etc., especially for some domestic mechanical presses, the largest slider The stroke is generally below 400mm. For the processing of hollow long-axis parts, due to the limitation of the stroke of the slider, hydraulic presses are used for forming. The forming speed of hydraulic presses is far lower than that of mechanical presses, so the forming efficiency is greatly reduced. The invention provides a lower mold base structure with a sliding plate. The sliding plate equipped with a multi-station mold is moved out from the bottom of the slider by the cylinder to perform the loading and unloading process. At the same time, a hydraulic cylinder jacking device is pro...
