Finding in practice, above-mentioned steel die structure is also unreasonable, and when making prefabricated component, there are the following problems:
1, for ease of the unlatching of long and short side form with close up, side form side has several through hole and is easy to the demoulding, when molding, through hole generally blocks with batten etc., but plug is susceptible to displacement even to come off, the concrete spillage of dies cavity can be caused, make that honeycomb, hole occur around prefabricated component, severely impacted quality and the outward appearance of prefabricated component；The concrete that through hole spills simultaneously easily condenses on side form, during the demoulding, it is necessary to is first removed by the spillage of solidification clean, adds many troubles；Owing to side form having multiple through hole, its intensity meeting degradation, yielding, even rupture, cause that dies cavity structure changes so that the prefabricated component of molding and the size of actual requirement exist deviation.
2, mainly relying on bolt to fasten location in existing mold between long side form and short side form, degree difference tightened by bolt, and the size of dies cavity will exist difference, causes the dimensional accuracy affecting prefabricated component.In practical operation, it is bigger by the impact of anthropic factor that degree tightened by bolt, it is not easy to controls, therefore the dimensional accuracy of the prefabricated component of existing mold production cannot be guaranteed.
Summary of the invention
The problem that prefabricated component for overcoming existing mold manufacture is of poor quality, dimensional accuracy cannot ensure, it is desirable to provide a kind of can the prefabricated-member mould of the quality of production is good, dimensional accuracy is high prefabricated component.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is as follows:
A kind of prefabricated-member mould of improvement, including bed die, two long side forms and two short side forms, two long side forms and two short side forms are respectively hinged at bed die surrounding and form rectangle frame, this rectangle frame matching bottom mould forms cavity body of mould, wherein to be provided with convex bittiness at long side form two ends, the same side that said two short side form correspondence convex is bittiness arranges angle mould, this angle mould has and the detent of the bittiness snap-fit engagement of convex, and said two short side form two ends are fastened on angle mould and long side form respectively through bolt.
Adopt the prefabricated-member mould of technique scheme, change the link position of angle mould, in prior art, angle mould is all provided in long side form two ends, by bolt again by angle mould and the fastening of short side form, when producing prefabricated component, first open short side form and long side form, the reinforcing bar of prefabricated component molding is put into cavity body of mould, then long side form, short side form are closed up successively, while short side form closes up, by in bittiness for the convex detent snapping in angle mould, followed by bolt by short side form and angle mould fastening, it does not have arrange the long side form of angle mould then either directly through bolt and the fastening of short side form.Owing to this prefabricated-member mould fetches, by the bittiness card that coordinates with detent of convex, the size ensureing dies cavity, avoid in original technology and only fix, with bolt, the size that long side form brings with short side form, now the bolt of the application only plays fixation, the size of dies cavity will not be impacted by its degree of tightening, therefore dies cavity has good reliability of positioning, and the preform sizes precision of production is higher.
Preferably, wherein it is provided with suspension hook outside a long side form.After prefabricated component molding, it is possible to mention the suspension hook outside long side form by hoisting machinery, thus being poured out from mould by prefabricated component, this can accelerate the formation efficiency of prefabricated component.
This invention has the advantages that the bittiness clamping that coordinates with detent of convex makes the dimensional accuracy of prefabricated component be improved compared to existing technology, and opening and closing up very convenient of mould, reduce labor intensity, improve production efficiency.
