The piston bearing surface of this kind of injection molding machine pull rod is the taper surface, when moving to the taper surface direction owing to the piston, on partial effort dispersion to the pull rod body of taper surface with the piston to prevented to avoid annular boss and pull rod body junction stress concentration, in order to reduce annular boss and the cracked risk in pull rod body junction because of on whole efforts of piston concentrate on annular boss.
Description
Technical field
The utility model relates to injection machine field, particularly a kind of injection machine pull bar with angle step.
Background technology
In injection machine running, often cause producing because of pull bar fracture and interrupt, cause huge economic loss to user.
Shown in Figure 4, existing injection machine pull bar (also known as guide pillar, brother woods post) comprises bar body 1, and bar body 1 is provided with the annular boss 11 for supporting piston 2, and annular boss 11 1 end face forms piston support face.Described piston support face is vertical plane 18, and vertical plane 18 is perpendicular to the central axis L of bar body 1.Described bar body 1 is piston construction section near described vertical plane 18 place, the periphery of piston construction section is provided with annular groove 15 and external screw thread 16, sealing ring 4 is provided with in annular groove 15, external screw thread 16 is connected with piston 2 and nut 3, piston 2 is set in outside piston construction section 17, piston 2 compresses and is connected on described vertical plane 18 and between nut 3, is sealed between piston 2 inwall and bar body 1 by described sealing ring 4.Described bar body 1 dorsad one end of vertical plane 18 is used for being connected with the rear plate of injection machine, and bar body 1 is used for being connected with the solid plate of injection machine towards one end of taper surface, not shown.
The vertical plane 18 contacted with annular boss 11 due to piston 2 is perpendicular to the central axis L of bar body 1, so when piston 2 is along D arrow direction, all directed force F vertically concentrate on annular boss 11, and annular boss 11 and bar body 1 junction E are easily ruptured.
Utility model content
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple and reasonable for structure, stressed well, the injection machine pull bar of the not band angle step of easy fracture.
The purpose of this utility model is achieved in that
With an injection machine pull bar for angle step, comprise bar body, bar body is provided with the annular boss for supporting piston, and annular boss one end face forms piston support face, and it is characterized in that, described piston support face is taper surface.
The purpose of this utility model can also adopt following technical measures to solve:
As scheme more specifically, the angle α of described taper surface and bar body central axis is 20 degree to 60 degree.Described angle α is preferably 60 degree, and the taper surface of this angle both can meet the requirement of supporting piston, also the active force of piston action in annular boss can be dispersed on bar body, thus reduces the risk of bar body fracture.
Described bar body and taper surface junction are provided with annular cancave cambered surface, eliminate the stress of taper surface and bar body junction further, prevent because taper surface and bar body junction stress are concentrated and ruptured.
Chamfered transition between the other end of described annular boss and bar body, to increase the intensity that annular boss is connected with bar body.
Described bar body is piston construction section near described taper surface place, the periphery of piston construction section is provided with annular groove and external screw thread, sealing ring is provided with in annular groove, external screw thread is connected with piston and nut, piston bush is located at outside piston construction section, piston compresses and is connected on described taper surface and between nut, is sealed between piston inner wall and bar body by described sealing ring.
Described bar body dorsad one end of taper surface is used for being connected with the rear plate of injection machine, and bar body is used for being connected with the solid plate of injection machine towards one end of taper surface, and described bar body is provided with compensating groove towards one end of taper surface.
The beneficial effects of the utility model are as follows:
(1) the piston support face of this kind of injection machine pull bar is taper surface, due to piston move to taper surface direction time, the partial action power of piston is dispersed on bar body by taper surface, thus prevent because whole force localization of piston are on annular boss, annular boss and bar body junction stress is avoided to concentrate, to reduce the risk ruptured in annular boss and bar body junction;
(2) object that this kind of injection machine pull bar arranges compensating groove is the adverse effect caused by reduction solid plate flexural deformation and four-pull-rod unbalance loading, reduces the risk of pull bar fracture further.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1 to Figure 3, a kind of injection machine pull bar with angle step, comprises bar body 1, and bar body 1 is provided with the annular boss 11 for supporting piston 2, and annular boss 11 1 end face forms piston support face, and described piston support face is taper surface 12.
Described taper surface 12 is 20 degree to 60 degree (the present embodiment angle α is 60 degree) with the angle α of bar body central axis L.
Described bar body 1 is provided with annular cancave cambered surface 13 with taper surface 12 junction.
Circular arc chamfering transition between the other end of described annular boss 11 and bar body 1.
Described bar body 1 is piston construction section 17 near described taper surface 12 place, the periphery of piston construction section 17 is provided with annular groove 15 and external screw thread 16, sealing ring 4 is provided with in annular groove 15, external screw thread 16 is connected with piston 2 and nut 3, piston 2 is set in outside piston construction section 17, piston 2 compresses and is connected on described taper surface 12 and between nut 3, is sealed between piston 2 inwall and bar body 1 by described sealing ring 4.
Described bar body 1 dorsad one end of taper surface 12 is used for being connected with the rear plate of injection machine, and bar body 1 is used for being connected with the solid plate of injection machine towards one end of taper surface 12, and described bar body 1 is provided with compensating groove 14 towards one end of taper surface 12.
The principle reducing the risk that annular boss 11 ruptures with bar body 1 junction is: shown in Figure 3, when piston 2 moves to taper surface 12 direction (the D direction of arrow), the directed force F of piston 2 ' be divided into two parts, on the annular boss that part directed force F 1 vertically acts on, another part directed force F 2 is dispersed on bar body 1 by taper surface 12, thus prevent because whole force localization of piston 2 are on annular boss 11, annular boss 11 and bar body 1 junction stress is avoided to concentrate, to reduce the risk ruptured in annular boss and bar body junction.
