Upper-turn and lower-move hydraulic punch type die closing machine

Abstract

The invention provides an upper-turn and lower-move hydraulic punch type die closing machine. The upper-turn and lower-move hydraulic punch type die closing machine is technologically characterized in that the four corners, corresponding to a lower machine base, of an upper machine base are provided with guide columns; the guide columns are sleeved with the four corners of a sliding machine base; a lifting oil cylinder is connected between the sliding machine base and the upper machine base; reversing oil cylinders are arranged on the sliding machine base; the lower ends of the reversing oil cylinders are hinged to an upper workbench; one edge of the sliding machine base is hinged to the upper workbench through hinges, and the other edge of the sliding machine base is connected to the upper workbench through a clamping shaft; limiting pins and two parallel guide rails are arranged on the lower machine base; a lower workbench with the four corners provided with trundles are arranged on the parallel guide rails; a transmission shaft is arranged between every two corresponding trundles; each transmission shaft is connected with a motor through a chain wheel structure; supporting oil cylinders of the lower workbench are further arranged at the four corners of the lower machine base; the oil cylinders are all connected with an oil tank through oil pipes. By means of the upper-turn and lower-move hydraulic punch type die closing machine, grinding, debugging and maintenance of a newly-developed die are greatly facilitated, and the die closing machine has the characteristics of being simple in structure, ingenious in design, scientific, practical and the like.

Description

technical field [0001] The invention belongs to the technical field of mold research and matching equipment, and in particular relates to an upturning and downmoving hydraulic stamping mold clamping machine. Background technique [0002] As we all know, the mold clamping machine is a professional mold research and matching equipment, which is mainly used to clamp the upper and lower molds with different pressures during the later research and matching of mold making. It adopts a variety of reliable devices, equipped with mobile table mold clamping and positioning device, upward moving flip locking device, mechanical flipping device, hydraulic ejector pin, mold slide control, safety anti-falling device, etc. It adopts PLC electric control technology, equipped with electric control box, electric control operation panel, and electromagnetic proportional valve. The mold clamping machine is safe and easy to operate, which effectively improves the production efficiency and produc...

Problems solved by technology

[0003] The overturning device of the existing equipment is unstable during the working process, which may easily cause the upper working plate to be biased and damaged; while the lower working plate adopts the moving mode of the sliding mechanism, the processing technology is complicated, and the wear is large, which may cause the positioning device to fail after repeated use , the lower table that cannot be positioned accurately will have a great impact on the production efficiency and product quality of the mold
