Abstract
The present invention is provided, a kind of die casting die joint bedding-in method, it is characterised in that the method comprising the steps of：Shaping lining mould, sliding block to die casting carry out preliminary bedding-in, require that contact area exceedes the 70% of die joint area under nature or the effect of smaller mold clamping force；Then, will shaping lining mould, sliding block be assembled to it is framed in, the overall lappingout for carrying out mould is matched somebody with somebody.It is applied in the method and improves die casting die joint quality of fit, improves bedding-in efficiency.It is the copper sheet for being uniformly distributed same dimensions during mould bedding-in in die joint, it is ensured that the depth of parallelism of active and inactive mold die joint.Finally, contact area reaches more than the 95% of die joint area after mould coordinates, with good bedding-in effect.
Description
Technical field
The present invention relates to a kind of fine bedding-in method of high-pressure casting mould, it is particularly suited for solving large mold die joint
Bedding-in precision problem not high.
Background technology
During Die Casting, die casting occurs sheet metal on die joint or moving part edge, also known as winged
Side.The presence of this defect, can directly affect the surface quality of die casting, even result in casting dimension unqualified.This defect
The reason for mainly have following several respects：One is that mould coordinates imprecision, die joint not to flush；Two be die casting machine clamp force it is inadequate
Or adjust incorrect；Three is inadequate mould strength, is deformed in production process；Four is that mold parting surface debris are not clear in producing
Reason is clean, and matched moulds is not in place；Five is too high injection speed, forms compression shock peak etc..
With in mold process, dynamic, cover half is closed tight to tradition by direct clapper die spotting press after being coloured to mold parting surface, and then basis is opened
Die joint coloring case is polished die joint after mould, and to being repaired at die joint laminating imprecision, the method is to parting
It is excessive that the bedding-in in face colouring region is likely to result in die joint polishing, die joint the situation that mill loses locally is occurred, and ultimately results in point
Type face can not reach the requirement of tight laminating, influence die joint quality of fit.
The content of the invention
The present invention relates to a kind of bedding-in improved method of high-pressure casting mould die joint, it is particularly suited for solving Large-scale High-Pressure
Casting mould die joint bedding-in precision problem not high.Tradition mould is integrally assembled completion, in mould molding portion with mold process
Directly dynamic, cover half is combined after point parting face colouring, appropriate pressurization, according to die joint coloring case to die joint after die sinking
Hard spot polished, to being repaired at die joint laminating imprecision, move in circles until reach requirement, but the method to point
The bedding-in in type face colouring region is likely to result in the situation that die joint polishing is excessive, loses die joint part appearance mill, ultimately results in
Die joint can not reach the requirement of tight laminating, influence die joint quality of fit.The present invention is evenly arranged together by die joint
The copper sheet of one thickness, and the copper sheet that successively decreases step by step during bedding-in thickness, then to active and inactive mold tool coordinate, remove
Hard spot on die joint.The present invention has the advantages that bedding-in efficiency high, quality of fit are high.
The invention aims to overcome the shortcomings of the above, there is provided a kind of quality of fit for improving die casting, carry
The mould bedding-in method of bedding-in efficiency high.
On the basis of traditional moulds bedding-in, the use copper sheet of novelty this auxiliary material coordinates the present invention in mould
During on die joint pad plus same dimensions copper sheet, then carry out matched moulds and the fabricator similar with traditional moulds bedding-in
Make, every time finishing after pad again plus next thickness copper sheet (copper thickness successively decreases step by step, such as 0.3mm → 0.2mm → 0.1mm →
0.05mm → 0), continue die joint bedding-in process, until die joint painted areas area ratio reaches more than 95%.
In one aspect of the invention, there is provided a kind of die casting die joint bedding-in improved method, the method includes step
Suddenly：(A) shaping lining mould to die casting, sliding block carry out preliminary bedding-in, are required under nature or the effect of smaller mold clamping force
Contact area exceedes the 70% of die joint area, comprises the following steps：Uniform coloring is carried out to mold parting surface；Only sound is served as a contrast
Mould die joint carries out bedding-in；Dynamic, cover half is coordinated using clapper die spotting press；Die sinking；Hard spot on active and inactive mold die joint is polished,
Polishing, described hard spot is that most of region does not colour or local colored region；Above step is repeated, continues bedding-in,
Until die joint colored contact area reaches more than 70%；(B) and then, will shaping lining mould, sliding block be assembled to it is framed in, carry out mould
The overall lappingout of tool is matched somebody with somebody, and is comprised the following steps：Uniform coloring is carried out to mold parting surface；Padded on die joint during bedding-in
Plus copper sheet, copper thickness successively decreases step by step；Dynamic, cover half is coordinated using clapper die spotting press；Die sinking；Hard spot on active and inactive mold die joint is entered
Row polishing, polishing, described hard spot are that most of region does not colour or local colored region；Repeat above step, pad
Plus thinner copper sheet；It is final to cancel copper sheet, continue bedding-in, until die joint colored contact area reaches more than 95%.
In currently preferred aspect, in step (B), pad adds copper sheet on die joint during bedding-in, and copper sheet is thick
Degree is set to 0.3mm, 0.2mm, 0.1mm and 0.05mm step by step.
It is applied in the method and improves die casting die joint quality of fit, improves bedding-in efficiency.It is mould bedding-in process
In the copper sheet of same dimensions is uniformly distributed in die joint, it is ensured that the depth of parallelism of active and inactive mold die joint.Finally, after mould coordinates
Contact area reaches more than the 95% of die joint area, with good bedding-in effect.
Specific embodiment
Embodiment 1
First, the forming module (lining mould, sliding block) to die casting carries out preliminary bedding-in, in nature or smaller matched moulds
Require that contact area exceedes the 70% of die joint area under power effect.Comprise the following steps：
1) uniform coloring is carried out to mold parting surface；
2) bedding-in only is carried out to sound lining mould die joint；
3) dynamic, cover half is coordinated using clapper die spotting press；
4) mold；
5) hard spot (most of region does not colour, local colored region) on active and inactive mold die joint is polished,
Polishing；
6) above step is repeated, continues bedding-in；
7) until die joint colored contact area reaches more than 70%.
Then, by forming module (lining mould, sliding block) be assembled to it is framed in, the overall lappingout for carrying out mould is matched somebody with somebody.Including as follows
Step：
1) uniform coloring is carried out to mold parting surface；
2) during bedding-in on die joint pad plus copper sheet, copper thickness successively decreases (0.3mm → 0.2mm → 0.1mm step by step
→0.05mm)；
3) dynamic, cover half is coordinated using clapper die spotting press；
4) mold；
5) hard spot (most of region does not colour, local colored region) on active and inactive mold die joint is polished,
Polishing；
6) repeat above step (copper sheet of pad plus next thickness continues to coordinate, until 0.05mm copper sheets)；
7) cancel copper sheet, continue bedding-in, until die joint colored contact area reaches more than 95%.
