The invention discloses a method for glass mould cylindrical machining. The method includes the steps of casting two half mould blanks, casting two projections at each end of each half mould blank, milling fitting faces of the two half mould blanks, fixing support blocks on a spindle and a tailstock in a machine tool, placing the half mould blank with the longer projections onto the support blocks, fixedly clamping the projections by fitting of a first clamp block and one support block, fastening the other half mould blank to the half mould blank fixed on the machine tool, fixedly clamping the projections of the two half mould blanks by fitting of a second clamp block and the first clamp block, and turning the cylindrical surface of the two half mould blanks by the machine tool. According to the method, the bottom of each projection is an extension part from the fitting face of the corresponding half mould blank; the length of the projections of one half mould blank is larger than that of the projections of the other half mould blank; the support faces of the support blocks are as high as the axis of a spindle of the machine tool. The method has the advantages that operations are simple, the half mould blanks are well symmetrical and efficiency is high.
Description
Technical field
The Excircle machining method and the special fixture thereof that the present invention relates to a kind of glass mold, be applicable to glass mold processing technique field.
Background technology
The general process step of glass mold is: the processing such as cast blank, the mating surface of processing two half modules, Excircle machining, die cavity processing, Cooling Holes locating slot.By the disclosed content of Chinese patent literature CN102059529A, the process of the existing general cylindrical for glass mold is, by one end of lathe chuck clamping glass die blank, the other end to mould machines, then unload glass mold, by process one end be clamped in the Vehicle Processing of carrying out the other end on lathe chuck.What this processing method adopted is to clamp processing twice, and as the general knowledge in machined field, clamping repeatedly will cause the increase of error, and then is difficult to the symmetry of two half modules that guarantee glass mold.Artificial adjustment glass mold axis is high to the requirement of workman's operating experience with overlapping of lathe spindle axis, weak effect, and time-consuming again, therefore this traditional mould Excircle machining method is inapplicable, to be improved.
Chinese patent literature CN102059529A improves for the problems referred to above, the mating surface of two of glass die blank half modules is being carried out after fine finishining, in the both ends of the surface of glass die blank two-half die, be respectively drilled with a pair of dowel hole, control the distance between a pair of dowel hole, the position of dowel hole on end face and the degree of depth of dowel hole.Then after two-half die being fastened, by dowel hole, coordinate mould is fixed on lathe and is machined with the alignment pin of lathe, although this processing method is jig accurately, guarantee the symmetry of two-half die, but its precision depends on the precision of the dowel hole of processing on the end face of two half modules, and need to guarantee the distance between dowel hole simultaneously, the precision of three parameters of the degree of depth of the position of dowel hole on end face and dowel hole could obtain the high symmetry of half module, therefore process is had relatively high expectations, each mould to be processed is needed to carry out dowel hole processing accurately, whole efficiency is lower.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the object of this invention is to provide a kind of Excircle machining method of glass mold, simplify the complicated processing to two-half die, once clamp the symmetry of guaranteeing two-half die, improve working (machining) efficiency.Another object of the present invention is to provide the special fixture that adopts the inventive method processing two-half die.
Technical scheme of the present invention is such: a kind of Excircle machining method of glass mold, is characterized in that: comprise the following steps:
1) cast blank, casts two half module blanks, at two end faces of half module, is cast with respectively two boss, and the bottom surface of described boss is the extension of half module mating surface, and the land length of one of them half module is longer than the land length of another half module;
2) mating surface of two half module blanks is carried out to milling processing;
3) fixed support block on the main shaft of lathe and tailstock, the supporting surface of described back-up block and the axis of machine tool chief axis are contour, the half module with longer boss is placed on back-up block, the mating surface of described half module is relative with the supporting surface of back-up block, the first fixture block coordinates boss is gripped with back-up block, another half module is fastened on the half module that is fixed on lathe, by the second fixture block, coordinate the boss of two half modules is gripped with the first fixture block; By lathe, two half module cylindricals are machined.
Preferably, position in order to ensure half module on back-up block is fixed, can when follow-up Vehicle Processing, not be subjected to displacement slippage, in described step 3, the half module with longer boss is placed on back-up block, the boss of described half module is provided with dowel hole, described back-up block is provided with alignment pin, described alignment pin is inserted to the position of determining half module in dowel hole.
Preferably, two boss on the end face of described half module lay respectively at the both sides of half module axis.
Glass mold Excircle machining special fixture, it is characterized in that: comprise the back-up block, the first fixture block and the second fixture block that are fixedly connected with tailstock with machine tool chief axis, described back-up block is provided with horizontal support face, the axis of described supporting surface and machine tool chief axis is contour, described the first fixture block is arranged on supporting surface top, vertically be connected by bolt with back-up block, described the second fixture block is arranged on the second fixture block below, is vertically connected by bolt with the first fixture block.
Preferably, described back-up block is provided with alignment pin.
Technical scheme provided by the present invention is determined the axis of machine tool chief axis by being fixed on back-up block on machine tool chief axis and tailstock, the mating surface of half module is directly aimed at the supporting surface of back-up block after milling processing, then fasten another half module, can simply make fast the axis of machine tool chief axis be positioned on the mating surface of glass mold of two half modules compositions machines again, wholely clamp simple to operately, and process only once clamps the symmetry of having guaranteed two half modules.When first, use back-up block, back-up block is adjusted to after correct position, each processing mold blank is all without additionally adjusting, improved working (machining) efficiency, lower to the requirement of process operation personnel operant level, mould symmetry does not rely on personnel's level yet, has guaranteed the uniformity of product quality.
