Abstract
The utility model discloses a connection structure for a nozzle of an injection molding machine and a front charging barrel. The nozzle is in threaded connection with the front charging barrel. The connection structure is characterized in that the sealing end surface of the nozzle and the front charging barrel are provided with annular material guide chutes, the nozzle is provided with material leaking holes, and the material leaking holes are communicated with the annular material guide chutes. The connection structure can prevent connecting threads of the nozzle and the front charging barrel from losing effectiveness, and greatly reduces the maintenance and production costs.
Description
Technical field
The utility model relates to the syndeton of a kind of injection machine nozzle and preceding barrel, can eliminate the problem that existing screw connection structure ridge profile is perishable or damage, thereby reduces the turnover rate of injection machine nozzle.
Background technology
In the molding machine injection process, the general employing of design that be connected of nozzle and preceding barrel is threaded, and for preventing in the injection process that melting material has leakage under the high pressure effect, adopts end face seal, referring to Fig. 1.And during actual production, under the high pressure P effect of plastics, cause the nozzle I to contact end face with preceding barrel II and produce distortion, make trace melt material and get into the threaded portion III through distortion place, corrode the ridge profile; Simultaneously because under the pressure P effect, the nozzle I produces the alternation active force with preceding barrel II connecting thread, make the antagonization that screw thread corrodes or curl up the limit and lost efficacy; After nozzle I and the corrosion of preceding barrel II connecting thread or damaging, need change nozzle I and preceding barrel II simultaneously, not only increased maintenance cost but also increased maintenance time and difficulty, reduced the production efficiency of injection machine, improve client's shutdown loss.
The utility model content
The utility model technical problem to be solved is to overcome deficiency of the prior art and provide a kind of nozzle and preceding barrel connecting thread of preventing to lose efficacy, and reduces maintenance and the injection machine nozzle of production cost and the syndeton of preceding barrel greatly.
The technical scheme that the utility model solves the problems of the technologies described above employing is: the syndeton of this injection machine nozzle and preceding barrel; Nozzle is threaded with preceding barrel; It is characterized in that: the seal face of described nozzle and preceding barrel is provided with annular deflector chute; Have material spilling hole on the nozzle, material spilling hole is communicated with annular deflector chute.
Have installing hole on the barrel before the utility model is described, nozzle one end is a connecting axle, and connecting axle is threaded with installing hole, and the length of installing hole is less than the length of connecting axle.
The utility model compared with prior art has the following advantages: contact with preceding barrel end face when compressing when nozzle in the utility model; Played the end face seal effect; Be milled with annular deflector chute on the sealing end face simultaneously, annular deflector chute is communicated with material spilling hole, even there is the material of melting to leak from seal face; Melting material can gush from material spilling hole through annular deflector chute; Stop to melt material and mixed the zone that is threaded, thereby solved the problem of ridge profile corrosion, thoroughly eliminated the drawback on the screw thread antagonization or the limit of curling up.
Description of drawings
Fig. 1 is a prior art.
Fig. 2 is the utility model structural representation.
Fig. 3 is an A portion enlarged drawing among Fig. 2.
The specific embodiment
Referring to Fig. 2 ~ Fig. 3, preceding barrel 2 is arranged on the barrel 3, and an end of nozzle 1 is a connecting axle 11, and preceding barrel 2 is provided with installing hole 21, and connecting axle 11 is threaded with installing hole 21.Because the length of the installing hole 21 on the preceding barrel 2 is less than the length of nozzle 1 connecting axle 11, when screwed, nozzle 1 contacts with preceding barrel 2 end faces and compresses, and has played the effect of end face seal.The seal face 6 of nozzle and preceding barrel is provided with an annular deflector chute 4, and nozzle 1 is provided with a plurality of material spilling holes 5, and annular deflector chute 4 is communicated with material spilling hole 5.When end face seal had leakage, leaking material can spill from material spilling hole 5 through annular deflector chute 4, thereby had solved the problem of ridge profile corrosion, had thoroughly eliminated the drawback on the screw thread antagonization or the limit of curling up.
Above embodiment has made comparatively detailed description to the utility model, but these descriptions are not to be the restriction to the utility model; The protection domain of the utility model comprises those conspicuous to those skilled in the art conversion or substitutes and remodeling.Allly conceive equivalence or the simple change that described structure, characteristic and principle are done, include in the protection domain of the utility model patent according to the utility model patent.
Claims (2)
1. the syndeton of an injection machine nozzle and preceding barrel, nozzle is threaded with preceding barrel, it is characterized in that: the seal face of described nozzle and preceding barrel is provided with annular deflector chute, has material spilling hole on the nozzle, and material spilling hole is communicated with annular deflector chute.
2. the syndeton of injection machine nozzle according to claim 1 and preceding barrel is characterized in that: have installing hole on the barrel before described, nozzle one end is a connecting axle, and connecting axle is threaded with installing hole, and the length of installing hole is less than the length of connecting axle.
