Description
Technical field
The present invention relates to screw for injection molding machine head unit, more specifically to a kind of assembled screw rod head.
Background technology
As everyone knows; existing standard screw head group is made up of three parts: screw head, check ring (crossing cushion rubber), meson; three assemblies of screw in injection molding machine head have played the functions such as the mixing plasticizing of sealing in whole piece screw rod group; it is an important part; the quality problems of many plastic cement products and screw head assembly have close relationship; often there is the detailed problem of many assemblies not handle well the percent defective of plastic cement products is significantly increased, even overhauled by forced-stopping machine.
If manufacture wear resistant corrosion resistant screw head group, three kinds of parts must be used the steel of same high abrasion highly corrosion resistant, material cost can be very high like this, and three kinds of parts are all high rigidity, just can reach wear-resisting effect, but toughness will decline when high rigidity, at this moment the connection tooth of screw head will be too hard, to toughness is declined, there will be risk of breakage, improve fracture probability.And the design of two end faces of crossing cushion rubber is also particularly important, much the faying face of crossing cushion rubber and meson of injection machine producer design is the flat gradient that do not have now, there are like this two harms: the one, plane contact does not have inclined-plane contact-making surface large, and what just contact than inclined-plane service life like that is short a lot; The 2nd, meson and inclined-plane has not just become a dead angle with junction screw head, and the raw material time stops once long and has stain and a jaundice.
The present invention is the technical problem based on above-mentioned existence just, screw head has been carried out to Structured Design, develop a kind of assembled screw rod head, connection matching relationship between each assembly of screw head is designed simultaneously, each assembly can be made up of different Steel materials, realize and optimize matched combined, and screw head of the present invention is for convenience detach, just can not mineralization pressure poor because dismantling after son head other part and screw rod, solve like this difficult problem of screw head dismounting difficulty.
Summary of the invention
Technical problem to be solved by this invention is to provide improves toughness and abrasion resistance, reduces screw rod fracture and solves the assembled screw rod head of dismounting difficulty.
Technical scheme of the present invention is: a kind of assembled screw rod head, it comprises son head, front meson, check ring, rear meson and connection wire rod, described connection wire rod two ends all have external screw thread, described son head is connected with the external screw thread of described connection wire rod one end by its internal thread, described front meson, check ring and rear meson are through the other end setting of described connection wire rod, the rear end of described son head is described front meson, and the centre of described front meson and described rear meson is described check ring.
Further, on described front meson external diameter, there are the multiple R of mixing grooves, described in to mix in the middle of R groove be the pin that mixes.
Further, also include center protective sleeve, described center protective sleeve is positioned at the centre of described front meson and described rear meson, and is positioned at described check ring.
Further, described front meson, check ring, rear meson are made by wear resistant corrosion resistant Steel material, and son head and connection wire rod are made with toughness best material.
In sum, the invention has the beneficial effects as follows: assembled screw rod the present invention of the present invention can be reached and be joined by steel optimization, the combination of different hardness, improve toughness, improve wear-resistant corrosion-resistant function, reach cost-saving, improve the object of quality, and assembled screw rod head of the present invention is for convenience detach, just can not mineralization pressure poor because dismantling after son head other part and screw rod, solve like this difficult problem of screw head dismounting difficulty.
Be described in more detail the present invention below by embodiment.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with accompanying drawing 1-Fig. 5.But protection scope of the present invention is not limited to this.
Screw rod is the nervous parts of injection machine, and its effect is that plastics are carried, compacting, fusing, stirred and exert pressure.All these is that the rotation in barrel completes by screw rod.In the time that screw rod rotates, there is friction and interaction in plastics between machine tube inner wall, screw channel bottom surface, screw head and plastics and plastics.Pushing ahead of plastics is the result of this movable combination, and the heat that friction occurs is also absorbed for progressive plastics temperature and molten plastic.The layout of screw head will directly have influence on the level of these effects.
The present invention has developed a kind of assembled screw rod head, referring to figs. 1 through Fig. 5, wherein show a kind of concrete structure of assembled screw rod head of the present invention, it comprises sub 1, front meson 2, check ring 3, rear meson 4 and connection wire rod 5, as shown in Figure 4, connection wire rod 5 two ends all have external screw thread, be connected with the external screw thread of connection wire rod 5 one end by its internal thread for sub 1, front meson 2, check ring 3 and rear meson 4 are through the other end setting of connection wire rod 5, as can be seen from Figure 1, the rear end of sub 1 is front meson 2, front meson 2 is check rings 3 with the centre of rear meson 4.
As shown in Figure 2, also having the multiple R of mixing grooves 6 on front meson 2 wherein, is the pin 7 that mixes in the middle of every two R grooves 6 that mix.
Except above-mentioned assembled screw rod head group is installed combination; also have six cover combined types; six successively part be respectively: son head, front meson, central sheath, check ring, rear meson and connection wire rod; be with the difference of above-mentioned the first combination; the second combination also includes center protective sleeve, not shown, and this center protective sleeve is arranged between front meson 2 and rear meson 4; and be positioned at described check ring 3, be enclosed within connection wire rod.
Because screw head can rotate when reinforced, to making check ring and front meson and the friction of rear meson production, intermetallic mutual friction, also shorten the life-span of three parts and reduced precision, for reaching best in quality and life-span, front meson of the present invention, check ring, rear meson, four parts of central sheath select best wear resistant corrosion resistant Steel material to make, thereby overcome this difficult problem, the alternative valency of son head and connection wire rod compares the best steel of high tenacity and manufactures, reaching of such six covers joined, can reach wear resistant corrosion resistant function, can improve again the toughness of screw head connection wire rod, reach saving cost, improve the object of quality.
Due to fabricated structure design of the present invention, each assembly can be arranged in pairs or groups by Steel material optimization, and the combination of different hardness improves toughness, improves wear-resistant corrosion-resistant function, reaches cost-saving, improves the object of quality.
Assembled screw rod head of the present invention is not limited to the structure in above-described embodiment, can carry out multiple modification, in a word, is not departing from all improvement within the scope of design creativity of the present invention all in protection scope of the present invention.
