Description
Technical field
The utility model belongs to mold parts field, relates in particular to a kind of screw thread locating stud.
Background technique
Locating stud is most widely used in mould.At the mould consisting of two-part or more parts, as press tool, injection mould etc., accurately locate the adjacent two-part of mould.It is high especially that their precision all requires, and if the words that only depend on bolt to fix template are not all right certainly, so only by locating stud, reach the object of location, or prevent mistake of mounting point, direction etc.In the equipment of some mechanical motion, there is certain application, be mainly used in the location positioning based on two-dimensional space.Existing mold, because its purposes is different, can be set different structures, for its location, needs different types of bearing pin, for the mould for some specific occasion, general locating stud is lower working life, can not stablize lasting being arranged on mould, thereby causes mould accurately not locate.
China Patent No.: 201220470323.3, open day: on 05 08th, 2013, disclose a kind of name and be called the patent document for the locating stud of press tool, this model utility relates to a kind of mould structure accessory, specifically relates to a kind of locating stud for press tool.Comprise the first cylindrical body, the second cylindrical body, three cylindrical body, the 4th cylindrical body, the 5th cylindrical body and the 6th cylindrical body that are linked in sequence from top to bottom, the first cylindrical body, the second cylindrical body, three cylindrical body, the 4th cylindrical body, the 5th cylindrical body and the 6th cylindrical aspect ratio are 9:1.5:8:1:3:4; The first cylindrical body, the second cylindrical body, three cylindrical body, the 4th cylindrical body, the 5th cylindrical body and the 6th cylindrical diameter are than being 2:1:2:2.2:1.6:1.4.This model utility is for the locating stud of press tool, and reasonable in design, can carry out various press tools effectively fastening spacing.But this model utility can not be applicable to all occasions, in the poor occasion of some environment, this model utility is lower working life, can not stablize lasting being arranged on mould.
Summary of the invention
the problem that 1, will solve
For the mould in some specific occasion, general locating stud is lower working life, can not stablize lasting being arranged on mould, thereby the problem that causes mould accurately not locate, the utility model provides a kind of screw thread locating stud, and it can screw by screw thread, thereby stablize, is firmly arranged on mould, mould is accurately located, for a long time deviation position not.
2, technological scheme
For addressing the above problem, the utility model adopts following technological scheme.
A screw thread locating stud, comprises the first cylindrical body, the second cylindrical body, three cylindrical body, the 4th cylindrical body and the 5th cylindrical body that are linked in sequence from bottom to top, on the first described cylindrical body, away from second cylindrical one end, is taper platform; The first described cylindrical body outer surface is provided with square threaded form; The 5th described cylindrical body outer surface is provided with V thread screw; Between described three cylindrical body and the 4th cylindrical body, be provided with hexagon nut.
Preferably, the first described cylindrical body, the second cylindrical body, three cylindrical body, the 4th cylindrical body and the 5th cylindrical aspect ratio are 5:2:4:3:3.
Preferably, the described non-taper platform of the first cylindrical body place, the second cylindrical body, three cylindrical body, the 4th cylindrical body and the 5th cylindrical diameter are than being 2:1:1.8:1.5:1.2.
The utility model can be used for die holder and the fixing locating stud of template of press tool, and reasonable in design can be carried out die holder and template effectively fastening spacingly, and the adjacent two-part of mould are accurately located.And can screw by screw thread, thereby stable being firmly arranged on mould accurately located mould, for a long time deviation position not.
3, beneficial effect
Than prior art, the beneficial effects of the utility model are:
(1) on the utility model the first cylindrical body, away from second cylindrical one end, be tap web platform; The first cylindrical body outer surface is provided with square threaded form; The 5th cylindrical body outer surface is provided with V thread screw, can screw by screw thread like this, thereby stable being firmly arranged on mould is accurately located mould, for a long time deviation position not.
(2) between the utility model three cylindrical body and the 4th cylindrical body, be provided with hexagon nut, can make it more stable, improve working life.
