Abstract
The injection device of soft thickness semisolid plastics comprises machine barrel, screw rod, nozzle and hydraulic jack and oil motor, it is characterized in that screw rod by screw rod 1, screw head 4 and be socketed in the outer baffle ring seat 5 of screw head, countercurrent ring 6 and wear-resistant 7 form; More machine barrel is organized cooling loop pipe 3 by encirclement screw rod 1 outer barrel 17 with the constant temperature that is linked in the barrel periphery and is formed.The utility model screw slenderness ratio is less, the existing prevention material injection of countercurrent ring adverse current has the shear action of minimizing again to prevent to destroy fibre length and proterties, is fit to the mixture of multiple soft thickness semi-solid resin and reinforcing material or the injection moulding of composite and uses.
Description
Technical field
The utility model relates to a kind of injection machine, a kind of injection device that is used for soft thickness semisolid plastics.
Background technology
Thermosetting plastics injection moulding, be with soft thickness semi-solid resin monomer or its mixture pre-thermoplastification of in the not high machine barrel of temperature, going ahead of the rest, make resin generation physical change and chemical change process slowly, and be irreversible, because soft thickness semisolid plastic molecules structure has the thread like body of some side chains or side chain, this linear molecule molecule activity under uniform temperature and pressure condition intensifies, plastics are softening, along with the further raising of temperature and pressure becomes the dictyosome structure by the flow regime crosslinking curing.Thereby soft thickness semisolid plastic injection moulding process condition control is had relatively high expectations, the The Nomenclature Composition and Structure of Complexes of soft thickness semisolid plastic injection equipment also has significantly different with common thermoplasticity injector, the preplasticizing temperature of machine barrel for example, when its temperature is low, material plasticizing deficiency then, mobile poor, add to the difficulties to injection; If temperature drift can make the flowability of material reduce, even hardening phenomenon takes place, unfavorable to moulding.Be that to be used for injection molding raw material be that resin adds mixing or the composite that mineral filler, colouring agent and fiber glass reinforcement are formed again, require the goods of moulding to have the mechanical strength height, corrosion resisting property is strong, the exhausted good characteristics of property of electric edge, thereby to the structural requirement difference of screw barrel, particularly in the process of preplasticizing screw rod rotation, prevent to shear fiber glass reinforcement, to guarantee the product molding quality as far as possible.
Summary of the invention
The purpose of this utility model is the problem that exists at above-mentioned soft thickness semisolid plastic injection device, design a kind of follow-on soft thickness semisolid plastic injection device, make soft thickness semisolid plastic injection equipment structure adapt to the requirement that the goods technical performance improves constantly.
Design of the present utility model is, the injection device of soft thickness semisolid plastics, it comprises machine barrel, be located at the screw rod in the machine barrel and nozzle and the hydraulic jack and the oil motor of machine barrel front end, it is characterized in that screw rod by screw rod, screw head and be socketed in the outer shelves ring seat of screw head, countercurrent ring and wear-resistant form; Machine barrel is formed with the Heng Wen Kong Zhi rotation snare pipe that is linked in the barrel periphery by surrounding the outer barrel of screw rod.
Owing to establish wear-resistant between screw head and the countercurrent ring, the separated attitude of countercurrent ring and screw head, during the screw rod rotation, countercurrent ring is not being followed the screw head rotation, thereby material flow is crossed the teeth groove of countercurrent ring and is that the straight-line pass countercurrent ring does not have shear action to it basically when storing, thereby can keep original length of glass fibre and proterties; Be when countercurrent ring and a shelves ring seat when contacting again, when just injecting material, thereby shelves ring seat and adverse current mutually fit the barrel deadend is stoped the effect of being played prevention material adverse current by the refluence of injection material.Be many groups Heng Wen Kong Zhi rotation circle pipe in parallel on the whole barrel outer race again, generally be circulation cooling circulating water or liquid, material pipe preformed material is remained in certain temperature range, make soft thickness semisolid plastics temperature not because of rising is difficult for flow condition, and can in time regulate the control temperature at any time.

The specific embodiment
The complete machine structure of the soft thickness semisolid of screw plastic injection equipment as shown in Figure 1, its main feature is that the less general L/D of soft thickness semisolid screw slenderness ratio is between 10～15, screw rod 1 total length is gradual change shape structure, screw head is tapered, to shorten the time of staying of material in machine barrel, different for reducing with soft thickness semisolid spiral shell to the structure of the excessive scissors action screw head 4 of material generation, shown in Figure 4, screw head is formed by being socketed in the outer shelves ring seat 5 of screw head, countercurrent ring 6 and wear-resistant 7.As shown in Figure 5, the front end of countercurrent ring 6 is that three space widths equate that profile of tooth 66 is identical with flute profile 61, and the countercurrent ring rear end is the annulus 64 of interior rounding arc angle, is provided with logical material circular hole 65 between tooth base and the annulus, and the big end of shelves ring seat is the cylinder of flange-like.The baffle ring cover for seat is outside screw head, and the annulus end 64 of countercurrent ring 6 packs into grade ring seat 5 small ends outsides again, the interior rounding arc angle that makes countercurrent ring annulus end just in time with the outer rounding arc angle of the big end of shelves ring seat tight fit mutually.When screw rod 1 rotates in barrel 17, the screw rod of gradual change constantly pushes material when being delivered to screw head, countercurrent ring 6 also is squeezed and breaks away from shelves ring seat 5, and before the countercurrent ring end tooth 66 because of wear-resistant 7 stop can not with the conical head of screw head 4 fit mutually, countercurrent ring is not subjected to about the screw rod revolving force and is auto state, material flows in the injecting cavity of screw head from the teeth groove 61 and the tooth root hole 65 of countercurrent ring 6, because countercurrent ring is not followed the screw rod rotation thereby is reduced shear action, and the chamfering structure at countercurrent ring two ends etc., the length and the rerum natura that keep glass fibre in the material, as shown in Figure 2.When flowing to, material stores when a certain amount of, the pressure extrusion countercurrent ring 6 of material plasticizing retreats to baffle ring seat 5, fit is compact state to make countercurrent ring rear end annulus 64 and shelves ring seat 5 hold mutually greatly, countercurrent ring and shelves ring seat are simultaneously with the barrel hermetic barrier, shown in Figure 3, produce the effect that stop material adverse current if start injecting program this moment.Therefore countercurrent ring not only plays the minimizing shear action but also the effect that stops the material adverse current is arranged.
The machine barrel of soft thickness semisolid plastic injection equipment is many group jacket type cooling water pipes 3, and be many group parallel-connection structures, 6 groups of jacket type cooling water pipes are arranged as shown in Figure 2, wherein there is one group to be the cooling collar of fines pipe 10 and nozzle 11, each group taps into water pipe 18 and outlet pipe 2 respectively, to keep circulating water temperature at 18～25 ℃, its Controllable Temperature is built in ± 1 ℃ of scope.
The work of the oil motor of this device, injection cylinder and Mode-locking oil cylinder is coordinated control by the computer control centre of injection machine, and the whole injection machine of software and hardware programme-control by computer respectively installs co-ordination.
