Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, the utility model comprises plasticizing assembly I, injection cylinder assembly II, oil motor assembly III and anti-saliva cylinder component IV.Plasticizing assembly I comprises nozzle 1, connector 2, screw rod 3, barrel 4, setscrew nut 6, retainer plate 7, flat key 26 and heating collar 27 and forms.Injection cylinder assembly II is by injection seat 5, bearing gland 9, oil sealing 11, wear ring 12, piston connector 15, oil cylinder bonnet 21, location copper sheathing 22, single face seal 23, oil seal collar 24.Oil motor assembly III is mainly by anti-dust seal 8, deep groove ball bearing 10, turning cylinder 17, motor seat 18, oil motor 19, deep groove ball bearing (small end) 20, thrust bearing 25.Anti-saliva cylinder component IV component part has: cylinder body 13, piston boit 14, oil cylinder cover 16 and some oil sealings are formed.
For realizing that plastics are by the process of solid particle to the molten mass plastics, this is finished by plasticizing assembly I and oil motor assembly III, the oil motor 19 that is loaded on the motor seat 18 rotates under the driving of oil pressure, and oil motor 19 is connected with turning cylinder 17 usefulness flat keys 26, turning cylinder 17 is connected with screw rod 3 usefulness flat keys 26 and with retainer plate 7 flat key 26 is pushed down, so corresponding drive turning cylinder 17 and screw rod 3, screw rod 3 is loaded on barrel 4 inside, barrel 4 usefulness setscrew nuts 6 are loaded on the injection seat 5, turning cylinder 17 drives screw rod 3 and rotates in barrel 4, make screw rod 3, barrel 4 produces frictional heating with plastic grain, impel plastics to dissolve, heating collar 27 heating that are provided with in barrel 4 outsides simultaneously make the plastics heating dissolve equally.For making turning cylinder 17 slow-roll stabilizations, turning cylinder 17 is provided with thrust bearing 25, be respectively arranged with deep groove ball bearing 10 and deep groove ball bearing (small end) 20 at turning cylinder 17 two ends, be loaded on piston connector 15 inside, and block deep groove ball bearing 10 with bearing gland 9 respectively, block deep groove ball bearing (small end) 20 with shaft block ring 26, make between turning cylinder 17 and the piston connector 15 and do not have relative play, promptly make it and to move axially, but turning cylinder 17 can radially rotate freely, and piston connector 15 does not rotate.
When preventing preformed, molten plastic guarantees in barrel 4, and do not leak from nozzle 1, need draw back simultaneously at preformed at screw rod 3, and anti-saliva cylinder component IV just played this effect.(injection seat 5 is provided with two earrings to the oil cylinder cover 16 of anti-saliva cylinder component IV with the injection seat 5 that is installed on of cylinder body 13 symmetries, the counterbores that two anti-saliva oil cylinders of installation are arranged on the earrings) on the both sides, and piston boit 14 1 ends are fixing with motor seat 18 with screw, and the other end moves in cylinder body 13 as plunger.The piston connector 15 of motor seat 18 usefulness screws and injection cylinder assembly is fixing, therefore, piston boit 14 moves, correlated parts (motor seat 18, piston connector 15, turning cylinder 17, screw rod 3) is corresponding moving, when the anti-saliva oil inlet and outlet A oil-feed of pressure oil from anti-saliva cylinder component cylinder body 13, and injection cylinder assembly II to be injected into oil-out B fuel-displaced, can promote piston boit 14, piston connector 15, turning cylinder 17, screw rod 3 and move; Therefore when limit preformed frontier defense saliva, screw rod 3 shrinks back, and at screw rod 3 heads, barrel 4 inside promptly are full of molten plastic, wait for next step action of injection.Play a guide effect when Dui Cheng anti-saliva cylinder component IV is to injection in addition, and when preformed, played the anti-rotation effect, therefore better guaranteed the stability of system when preformed and injection.
Action of injection is finished by injection cylinder assembly II.Injection seat 5 inwalls have charging aperture D as an injection cylinder body on the injection seat 5.Piston connector 15 1 ends are piston portion, and two wear rings 12 and an oil sealing 11 are housed on it, and the other end of piston connector 15 is the rod member part.At oil cylinder bonnet 21 single face seal 23 is housed, and is located with location copper sheathing 22, oil seal collar 24; When preformed finishes, pressure oil enters from the oil-out B that is injected into of oil cylinder bonnet 21, promotes piston connector 15 and moves, and drives motor seat 18, piston boit 14, turning cylinder 17 and screw rod 3 equally and moves, screw rod 3 promotes its head molten plastic of preformed, and molten plastic is injected mould C.And the rod member part of piston connector 15 contact with location copper sheathing 22 when mobile, and piston is played positioning action, therefore eliminated the problem that piston rocks when injecting.This has just finished a preformed action of injection.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
