Abstract
The invention discloses a kind of processing technology of overlength heat seal dies, it comprises the following steps：1) blank prepares：The steel processing squarely blank for not doing Quenching Treatment is taken, 0.25~0.3mm surplus is stayed on each side of blank, and the degree of being mutually perpendicular in the face of blank six is controlled within 0.01mm；2) open thick：Roughing is carried out to six faces of blank, the unnecessary surplus of profile is removed, reduction is deformed because surplus is more, and 0.2~0.25mm surplus is stayed on each side of blank；3) school is deformed：In heat distortion direction in the reverse direction, school deformation ensures 0.05~0.1mm of deformation；4) it is heat-treated：Blank after roughing is quenched, is tempered, and checks hardness；5) finish：Six faces of the blank after Overheating Treatment are finished；6) processing tooth ensures that space width is uniform in place, and the dislocation of upper and lower mould tooth, which coordinates, during sealing ensures that sealing is more firm.The present invention is by using the deformation produced when machining and making its deformation offset heating, the problem of partially sealed bad caused by deformation when solving mould heating.
Description
【Technical field】
The invention belongs to technology of die manufacturing field, more particularly to a kind of processing technology of overlength heat seal dies.
【Background technology】
At present, there is a kind of strip product, it is molded by molding Shooting Technique, and it is used to be molded the strip product
Die cavity in mould is then string configuration, and in injection, upper and lower mould needs sealing, because its size is larger, therefore to mould
The planarity requirements on surface are very high, and the product needs to heat mould in forming process, therefore, using existing work
The mould of skill manufacture is easily deformed on using face after the heating, so as to cause have local bad cracking gas leakage at sealing
Phenomenon.
Therefore, it is necessary to provide a kind of processing technology of new overlength heat seal dies to solve the above problems.
【The content of the invention】
It is a primary object of the present invention to provide a kind of processing technology of overlength heat seal dies, mould heating is solved
When deformation caused by formed product it is bad the problem of.
The present invention is achieved through the following technical solutions above-mentioned purpose：A kind of processing technology of overlength heat seal dies, its
Comprise the following steps,
1) blank prepares：The steel processing squarely blank for not doing Quenching Treatment is taken, 0.25~0.3mm's stayed in each side of blank
Surplus, the degree of being mutually perpendicular in the face of blank six is controlled within 0.01mm；
2) open thick：Roughing is carried out to six faces of blank, the unnecessary surplus of profile is removed, reduces and produces change because surplus is more
Stay 0.2~0.25mm surplus in shape, each side of blank；
3) school is deformed：In heat distortion direction in the reverse direction, school deformation ensures 0.05~0.1mm of deformation；
4) it is heat-treated：Blank feeding heat-treatment furnace after roughing is quenched, is tempered, and checks hardness；
5) finish：Six faces of the blank after Overheating Treatment are finished；
6) processing tooth ensures that space width is uniform in place, and the dislocation of upper and lower mould tooth, which coordinates, during sealing ensures that sealing is more firm.
Further, in the step 4, hardening heat is 980~1010 DEG C, and temperature is 180~200 DEG C.
Compared with prior art, a kind of beneficial effect of the processing technology of overlength heat seal dies of the invention is：Profit
The deformation produced when making its deformation offset heating with machining, is solved partially sealed bad caused by deformation when mould is heated
The problem of.
【Embodiment】
Embodiment：
The present embodiment is the processing technology of overlength heat seal dies, and it comprises the following steps：
1) blank prepares：The steel processing squarely blank for not doing Quenching Treatment is taken, 0.25~0.3mm's stayed in each side of blank
Surplus, the degree of being mutually perpendicular in the face of blank six is controlled within 0.01mm；
2) open thick：Roughing is carried out to six faces of blank, the unnecessary surplus of profile is removed, reduces and produces change because surplus is more
Stay 0.2~0.25mm surplus in shape, each side of blank；
3) school is deformed：In heat distortion direction in the reverse direction, school deformation ensures 0.05~0.1mm of deformation, school deformation side
To with deformation direction after heating conversely reach heating after deformation and the deformation before heating cancel out each other, it is ensured that heating rear mold
Tool surface planarity reaches requirement；
4) it is heat-treated：Blank feeding heat-treatment furnace after roughing is quenched, is tempered, and checks hardness, its
Middle hardening heat is 980~1010 DEG C, and temperature is 180~200 DEG C；
5) finish：Six faces of the blank after Overheating Treatment are finished；
6) processing tooth ensures that space width is uniform in place, and the dislocation of upper and lower mould tooth, which coordinates, during sealing ensures that sealing is more firm.
The beneficial effect of the processing technology of the present embodiment overlength heat seal dies is：Its deformation is supported using machining
Disappear the deformation produced when heating, the problem of partially sealed bad caused by deformation when solving mould heating.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.
