Abstract
The utility model discloses a plastic injection molding machine nozzle with a filter screen, and relates to an injection molding machine nozzle, which comprises a nozzle seat and a nozzle head, and is characterized in that a filter screen tooth cylinder is also arranged in the nozzle seat and is tightly pressed in the nozzle seat by the nozzle head, and a matrix of the tooth cylinder is of a tubular body with a rightward opening; the outer circle of the tubular body radially extends to form six long strip-shaped arc teeth, and the arc teeth protrude out of the left end surface of the tubular body along the length direction to form six arc tooth lug bosses; and the outer arc tooth tips of the arc teeth are dynamically matched with the middle inner circular wall of the tubular body of the nozzle seat, and six rows of uniformly distributed small filter holes are circumferentially arranged between the inner wall of a central blind hole of the tubular body of the matrix of the tooth cylinder and the tooth bottom circles of the six arc teeth. The utility model has the advantages of moderate filter of rubber material, easy removal and clean-up, and pressure reducing performance, and the filter gap can be increased by grinding the circumference. Before molten plastic enters the nozzle, solid impurities such as copper scale can be filtered by the filter screen so as to prevent the blockage caused by the impurities which enter the nozzle and the hot runner of a mould, and thereby, the mould forming failure problem caused by the blockage of the impurities can be effectively solved.
Description
Technical field:
The utility model relates to the injection machine nozzle.
Background technology:
Plastic cement injection machine through type injection nozzle structure is made up of nozzle seat, nozzle head at present; The nozzle seat is an opening cylindrical body left, the right tube of the cylindrical body end step cylinder that extends to the right, and this step cylinder cylindrical is an external screw thread, and interior circle is the through hole that is communicated with medium pore at the bottom of the tube, and cylindrical body left end inwall is provided with internal thread; Nozzle centriciput cylindrical is the hexagon cylinder, extend and the step cylinder in the right surface of this cylinder, this step cylinder cylindrical is and the corresponding external screw thread of cylindrical body left end inwall internal thread, hexagon cylinder left end is a ball-crown body, and ball-crown body, hexagon cylinder, step cylinder three central authorities are provided with through hole; The nozzle seat is connected with the nozzle head thread, and nozzle seat left end external screw thread is implemented to be threaded with sprue.
This nozzle is the short tube shape, and flow of melt pressure and thermal loss when this nozzle is all very little, and is difficult for producing the material and decomposing of stagnating, so heater is not generally set up in its outside.But because the nozzle body is shorter, the length that puts in the cover half plate hole is restricted, so the sprue of mould therefor is longer.For remedying the length that this defective strengthens nozzle, form when becoming a kind of the changing of through type nozzle is called the extension nozzle again.This nozzle must add heat setting.More than two kinds of nozzles be applicable to the full-bodied plastics of processing, during processing low viscosity plastics, can produce the hydrostomia phenomenon.
The mouth of a river adds labor and materials and very easily causes mold hot runner system cast gate to stop up; When producing the ask for something high product, also cause the generation of defective products easily.When using the through type nozzle, the metal in the melt or nonmetal material can often stop up tiny cast gate, thereby need tear a mold cleaning hot runner system fully open.Nozzle is installed filter screen then can isolate those impure material effectively from melt.To hot runner system, the tight security that nozzle installation filter screen nozzle is had is in the practice approval.Even using best but can not guaranteed pure raw material too.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of plastic cement injection machine band filter screen nozzle is provided.
Scheme of the present utility model is: also be provided with screen pack tooth cylinder in the nozzle seat, the nozzle head is pressed on the tooth cylinder in the nozzle seat; Tooth cylinder matrix is an opening cylindrical body to the right, this cylindrical body outer circle diameter outwards extends and six strip arc teeth, the outstanding cylindrical body left side of arc tine length forms six arc tooth boss, and arc tooth external arc tooth top and nozzle seat cylindrical body middle part inner round wall are state movingly; Circumferentially be provided with the uniform radially little filter opening of six rows at the bottom of tooth cylinder matrix cylindrical body central blind hole inwall and six the arc tooth teeth between the circle.
Advantage of the present utility model is: 1 sizing material filters gentle; 2 readily removable removing are cleared up; 3 have the pressure of falling; 4 time of filtration can strengthen by rounding week.The plastics of fusion enter solid impurities such as can seeing through above-mentioned filter screen filtering copper scale before the nozzle, avoid impurity to enter nozzle and mold hot flow results in blockage, and have effectively solved because of impurity and have stopped up the mould molding failure problems that causes.

Fig. 4 is the C-C cutaway view of Fig. 1.
The specific embodiment:
Structure of the present utility model comprises nozzle seat (2), nozzle head (1), it is characterized in that also being provided with in nozzle seat (2) screen pack tooth cylinder (3), and nozzle head (1) is pressed on tooth cylinder (3) in the nozzle seat (2); Tooth cylinder (3) matrix is an opening cylindrical body to the right, this cylindrical body outer circle diameter outwards extends and six strip arc teeth, the outstanding cylindrical body left side of arc tine length forms six arc tooth boss, and arc tooth external arc tooth top and nozzle seat (2) cylindrical body middle part inner round wall are state movingly; Circumferentially be provided with the uniform radially little filter opening of six rows at the bottom of tooth cylinder (3) matrix cylindrical body central blind hole inwall and six the arc tooth teeth between the circle.
Melt is introduced into tooth cylinder (3) central blind hole from nozzle seat (2) right-hand member medium pore, extrude in the little filter opening of six rows in being extruded again, this moment, impurity was blocked in the blind hole by the restriction of aperture bore, after melt is extruded from the little filter opening of six rows, enter the arc tooth boss space of left end along arc tooth roller seating space, from between arc tooth boss roller seating space, enter central space of circles again, and then inject nozzle head (1) medium pore.
Screen pack does not adopt screen cloth mesh formula device, mainly be since among melten gel the mesh formula be heated yieldingly, or fusing do not have filtration, so the utility model adopts solid deep hole formula.
