Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figures 1 to 4, this crosses the screw rod 30 that glue head group part comprised glue head 10, was set in the cushion rubber 20 excessively on glue head 10 and was connected with mistake glue head 10 tailing screw flight, offer multiple grooves 50 of axially arranging and around the multiple cannelures 60 crossed glue head 10 circumferential lateral surface and arrange, each cannelure 60 is vertical with each groove 50 respectively to be arranged crossing glue head 10 head.
In conventional art, part is mixing just carries out mixing by screw rod 30 spiral shell rib to plastics in the rotation process of screw rod 30 in injection machine plasticizing, and after use certain hour, screw rod 30 can wear and tear, melting effect also can reduce gradually, now just needs the screw rod 30 of the mixing design of belt replacement to make up.
But screw rod 30 production cycle is long, manufacturing cost is high, change also inconvenient.Therefore the utility model devises one and crosses glue head group part, screw rod 30 pairs of melts can be replaced to stir and evenly mix further, can significantly improve melting effect in mixing process.In addition, cross glue head 10 easily manufactured, served as glue head 10 and reached useful life period in limited time, changed glue head 10, it is convenient to change.
The nozzle segment of injection machine comprises nozzle (not shown) and precursor flange (not shown), the head crossing glue head 10 stretches into precursor flange, and melt enters precursor flange via screw rod 30, excessively cushion rubber 20, excessively glue head 10 successively and carries out course of injection.Melt, when entering to cross glue head 10, carries out stirring mixing process again, improves the mixing degree of melt, strengthens melting effect.
Offering of each groove 50, each cannelure 60 is to cross glue head 10 and be arranged to the structure of polygon many ribs, and when screw rod 30 drove glue head 10 to rotate, can carry out axial stirring simultaneously, radially to stir, mixing stirring was comparatively thorough, makes melt more even.
Further preferably, groove 50 is uniformly distributed around crossing glue head 10 and is equipped with fin 70 between adjacent two grooves 50, each fin 70 all offers multiple breach of equidistantly distribution, be positioned at each breach head and the tail UNICOM on same cross section and form above-mentioned cannelure 60.
Breach one_to_one corresponding on two adjacent fins 70 is arranged, the position at each breach place namely on each fin 70 is consistent with the position at each breach place on all the other fins 70, so, be positioned at each breach ability head and the tail UNICOM on same cross section and form above-mentioned cannelure 60, wherein, each cannelure 60 all with each vertical UNICOM of groove 50.
And in fact, the existence of each breach all to be offered around all fins 70 by each cannelure 60 and is formed, each fin 70 is cut into multiple tooth block by each cannelure 60, such structural design can strengthen the melting effect of melt largely, melt is more even, and the quality of the product of injection mo(u)lding is also better.
Groove 50, cannelure 60 can according to actual needs and result of use select the quantity that is applicable to, in the present embodiment, the quantity of groove 50 is preferably eight, the quantity of fin 70 is also eight, and the quantity of cannelure 60 is preferably two, therefore, the quantity of the breach on each fin 70 is two.
Preferably, cross glue head 10 and comprise operate portions 11, connecting portion 12 and the transition part 13 for connecting operate portions 11 and connecting portion 12, and operate portions 11, connecting portion 12, transition part 13 three are connected as a single entity, crossing cushion rubber 20 is set on transition part 13, screw rod 30 is connected with connecting portion 12, and each groove 50, each cannelure 60 are all opened in operate portions 11.
Further preferably, transition part 13 is provided with annular shoulder 131, annular shoulder 131 crosses rubber gasket 40 crossing to be provided with between cushion rubber 20 and screw rod 30 to be resisted against, and cross rubber gasket 40 and fit tightly with screw rod 30.
Operate portions 11 stretches in the precursor flange of injection molding machine nozzle part, and particularly, melt enters be between cushion rubber 20 and transition part 13 through screw rod 30, excessively rubber gasket 40, then enters into operate portions 11.In whole process, melt is all mixing what carry out in varying degrees, and main mixing process is in operate portions 11.
Crossing rubber gasket 40 one end is resisted against on annular shoulder 131, and the other end and screw rod 30 fit tightly, and makes rubber gasket 40 can keep a stable state in injection moulding process.
Cross the relative glue head 10 of crossing of cushion rubber 20 can move axially, serve as cushion rubber 20 with when rubber gasket 40 fits tightly excessively, melt reverse flow (namely melt flowed to rubber gasket 40 from crossing between cushion rubber 20 and transition part 13) can be prevented, avoid impacting injection moulding process, good working effect.
Preferably, the circumferential lateral surface crossing rubber gasket 40 offers equally distributed multiple flow path groove 41.Offered flow path groove 41, will form projection between two adjacent flow path grooves 41, flow path groove 41 and projection cooperatively interact work, constantly rotate, can carry out milling work to the melt flowing through rubber gasket 40 under the drive of screw rod 30.
This crosses glue head group part in an initial condition, melt enters be between cushion rubber 20 and transition part 13 through screw rod 30, excessively rubber gasket 40, enter into operate portions 11 again, the setting of each groove 50, each cannelure 60 in operate portions 11, further mixing stirring is carried out to melt, strengthen melting effect, melt mixing is more even.The whole modular construction of glue head is excessively simple, easy and simple to handle, melting effect is good, and installs replacing conveniently, is worth widely using.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
