Detailed description of the invention

Below in conjunction with embodiment in detail the present invention is described in detail, object is only to understand content of the present invention better.Therefore, the cited case does not limit the scope of the invention.

The method of quickly replacing mould described in the present embodiment, carry out in the steps below:

(1) DATA REASONING is carried out to the mould 1 shown in Fig. 1.Mould 1, when designing, for the ease of lifting, is provided with lifting bolt hole 2 in mould 1 both sides, needs to measure this hole for hoist position and size, so that the manufacturing and designing of follow-up die clamp.

(2), after lifting bolt hole 2 position and size are determined, start to make die clamp.See Fig. 2, Fig. 3, the main body of die clamp is made up of connecting plate 3 and the bearing plate 4 be welded on connecting plate 3 outer panel face, and corresponding through hole 5 is offered in lifting bolt hole 2 position on connecting plate 3 on corresponding mould 1, and on connecting plate 3 bottom is fixing buckle 6.Die clamp makes four, and two pieces is a set of, is respectively used to quick mould unloading and quick die change.

(3) translation frock is made.See Fig. 4, the main body of translation frock forms by travelling bogie 7 and with the frame structure frame 8 that travelling bogie 7 is welded as a whole, and adopts framework fixed form to fix jack 9, to facilitate dismounting in frame structure frame 8.Frame structure frame 8 side is fixed with and coordinates locked lower buckle 10 with the upper buckle 6 on die clamp.Translation frock quantity is identical with die clamp quantity, same makes four, two pieces be a set of with the use of.

(4) mould unloading (see Fig. 5, Fig. 6):

(I) aborning, lifting bolt hole 2 position of mould 1 is positioned at both sides before and after overall press.Therefore, the first step, is first lifted into the both sides, front and back of mould 1 respectively with overhead traveling crane by two pieces die clamp, then by the through hole 5 on the connecting plate 3 of die clamp and the lifting bolt hole 2 on mould 1, is connected on mould 1 with bolt 11 by die clamp;

(II) second step, shifts the die clamp place of both sides before and after mould 1 respectively onto by two pieces translation frock, then buckled into by the lower buckle 10 in translation frock in the upper buckle 6 on die clamp.Because upper buckle 6 gap is greater than lower buckle 10, so now translation frock and die clamp entirety are in released state.So the bearing plate 4 on the jack 9 jacking die clamp in translation frock will be used, by die clamp and mould 1 jack-up simultaneously, until upper and lower buckle is locked.

(III) the 3rd step, uses jack or additive method push-and-pull translation frock, utilizes travelling bogie 7 to take turns right rolling, left behind by mould 1 from workbench.

(5) change the outfit new die: while mould unloading, assembling complete in advance, after first set mould mould unloading, being shifted onto other two pieces die clamp and other two pieces translation frock and new die to be changed on workbench by new die to be changed fast by unloading modeling method.
