Description

A press medicine mould for large aperture area back taper explosive grain Technical Field The invention relates to the technical field of explosive production equipment, in particular to a pressing die for large-aperture explosive columns with inverted cones. Background In order to ensure the safety of the pressing mould of the large-aperture grain, the mould designed according to the design principle of the pressing mould is very heavy, and the labor intensity is very high when the mould is assembled in the pressing process. For the grain with the conical structure, the forward pressing and the reverse die withdrawal are generally adopted, and because the die assembly table surface is higher from the ground, people stand on the ground to reverse the die without exerting force, and the people need to climb to the operation table to reverse the die. In addition, after the die with the design structure is assembled into the die withdrawing device, the total height is higher and is far greater than the height of the explosion-proof window, so that the die withdrawing device cannot be assembled outside the explosion-proof room, part of die accessories need to be opened to enter the explosion-proof room for assembly, and the explosive column is easy to drop suddenly and damage and be bumped by the punch in the die withdrawing mode.
