Overturning device of upper die for die spotting hydraulic press

Abstract

The invention discloses an overturning device of an upper die for a die spotting hydraulic press. The overturning device comprises a die spotting hydraulic press sliding block and a die spotting hydraulic press base, wherein the die spotting hydraulic press sliding block is matched on the die spotting hydraulic press, and is driven to be acted along the vertical direction by a driving mechanism; the overturning device further comprises an overturning plate, an overturning telescopic cylinder, an overturning plate guide rail, wherein the overturning plate is located below the die spotting hydraulic press sliding block, the hinged end of the overturning plate is hinged to one side of the die spotting hydraulic press sliding block, the free end and the other side of the die spotting hydraulicpress sliding block forms the detachable connection, the bottom surface of the overturning plate is used for fixedly installing the upper die of the die spotting hydraulic press, the top surface of the overturning plate is provided with a hanging point, the overturning telescopic cylinder is located in an inner space of the die spotting hydraulic press sliding block, a cylinder body of the overturning telescopic cylinder is hinged to the die spotting hydraulic press sliding block, a hook is arranged at the extension end of the piston rod, the hook opening of the hook faces the horizontal direction to form a hanging fit with the hanging point on the top surface of the overturning plate, the overturning plate guide rail is fixed on the die spotting hydraulic press base, the extension direction of the extending end of the overturning plate guide rail is the same as the hook opening of the hook, and is used for guiding the free end of the overturning plate and forming support for the overturning plate.

Description

technical field [0001] The invention relates to the field of molds, in particular to an overturning device for an upper mold of a mold grinding and matching machine. Background technique [0002] When repairing the upper mold on the mold grinding machine, because the working surface of the upper mold maintenance and grinding faces downward, it is very inconvenient to maintain and polish, the labor intensity is high, and the maintenance efficiency is low. In addition, the dust generated by grinding is downward under the action of gravity. Scattered, easy to enter human eyes, and extremely unsafe. [0003] Therefore, how to efficiently and safely maintain and polish the upper mold of the mold grinding machine is a problem to be solved urgently by those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to address the deficiencies of the prior art, to provide a flipping device for the upper mold of the mold grinding and matching ma...
