Definitions

  • the invention relates to an injection unit, which is movable with a chassis on slide rails of the machine stand of an injection molding machine and has a drive unit for axial displacement and pressing of the plasticizing cylinder to the injection mold.
  • the injection unit of an injection molding machine belongs, in addition to the actual casting molds and the closing mechanism for the casting molds, to the main assemblies of an injection molding machine.
  • the central function of the injection unit is the processing of the plastic melt, the metered feeding of the melt into the cavities of the injection mold and the construction and maintenance of the required pressure for the Spntzgiessmaschine until their solidification.
  • the plasticizing cylinder has a nozzle closure
  • the individual injection phases can be defined in terms of time as well as pressure.
  • the so-called freezing of the melt in the transition region from the plasticizing screw to the entry into the mold is utilized, the corresponding parameters must additionally be taken into account in the control / regulation.
  • the mechanical reaction forces from the internal pressure of the melt in the two mold halves must be compensated. The compensation forces in relation to the entire closing unit are absorbed by corresponding components, in particular the drive and a column bracing.
  • the plasticizing cylinder tip is pressed against the mold to such an extent that the melt pressure under no circumstances opens the contact point between the plasticizing cylinder tip and the mold, thereby causing melt to escape.
  • the discharge of melt is disadvantageous with respect to the cleaning of the relevant machine parts.
  • the much more serious disadvantage is the disturbance in terms of weight accuracy of the injection molded parts, since even with the greatest possible accuracy of the melt dosage, an uncontrollable amount is lost in the transfer area.
  • the opening of the contact point between the plasticizing cylinder tip and the mold was prevented by maintaining the pressing force of the plasticizing cylinder constant for the entire casting cycle with a high safety factor and with the highest contact force.
  • the basic solution for pressing the injection unit was invented, as it were, with French Patent No. 1 184 455, which to this day represents a successful practical solution.
  • the contact pressure is automatically regulated.
  • the relatively large contact forces are compensated by two tie rods.
  • the two tie rods are arranged in a common plane with the axis of the plasticizing cylinder. This results in the great advantage of a direct compensation of the pressure and contact forces.
  • the EP-PS 0 422 224 has solved the approach of direct balance of forces and proposes to arrange the injection unit slidably on slide rails of the stator of the injection molding machine.
  • the required force is converted via a ball screw transmission in a linear motion for the process and the pressing of the plasticizing.
  • contact pressure does not take place directly via the motor torque, but rather via the clamping force built up immediately after contacting the mold in two springs.
  • the balance between the spring forces and the Rekations takes place completely on the stand of the injection molding machine.
  • EP 0 422 224 The big disadvantage of solutions according to EP 0 422 224 lies in the eccentric generation of the contact pressure. Although EP 0 422 224 is able to avoid the problem of deformation of the mold by appropriate control of the contact pressure. However, uncontrollable forces which result, whether due to inaccuracies in the structural design, insufficient centering of the plasticizing cylinder tip and the injection port or from the eccentricity of the introduction of force, are not resolved. It must be taken into account here that contact stresses of the order of magnitude of 100 kg / cm 2 up to 300 kg / cm 2 are produced by the contact forces. These contact loads between the plasticizing cylinder tip and the corresponding contact point of the injection mold are able to transfer large lateral forces due to the strong frictional action.
  • EP 0 627 289 is based on the basic concept of direct balance of forces in the vicinity of the plasticizing cylinder according to FR-PS 1 184 455.
  • the injection unit has a carrier block which is movably mounted on slide rails of the stator.
  • the visible disadvantage lies in the enormous effort required for the displacement and pressing function of the plasticizing cylinder by the use of two parallel guide columns.
  • DE 195 80 020 proposes a similar concept as EP 0 627 289.
  • the spray nozzle is braced with the mold and the nozzle contact force is set spring-free, depending on the spraying force or the pressure of the spray mass.
  • This solution has only partially succeeded in practice, although it combines several advantages of different solutions.
  • the solution according to DE 195 80 020 requires a considerable structural complexity through the double arrangement of the guide columns and the force balance.
  • the invention has now been based on the object to seek a solution which is structurally simple, allows a central force introduction with the best possible sealing, but without the described disadvantages of the solutions of the prior art.
  • the solution according to the invention is characterized in that the injection unit is supported by means of a carrier displaceably arranged on the stand of the injection molding machine and has a single drive, by means of which the plasticizing cylinder can be pressed against the injection mold with centric sealing engagement.
  • the carrier is inserted as a separate component.
  • the carrier may each take on additional special functions, as set out below.
  • the carrier is designed as a chassis, with a chassis, which preferably has four sliding shoes. This means that the carrier with the landing gear completely carries the injection unit.
  • the carrier has upwardly two lateral support cheeks, which give the plasticizing a pivotal support via pivot.
  • the injection cylinder receives in a vertical plane easy pivoting for adjusting the nozzle tip.
  • the forces acting through a single drive are centrically initiated with respect to the sealing. Although the force generation occurs at a distance and parallel to the axis of the plasticizing cylinder, the power transmission through the articulated connection does not give any transverse forces on the mold.
  • the carrier also has downwards a tab connection with a second articulation point for a drive axle. The power transmission takes place thereby both in the upper part of the carrier as in the lower part of the carrier via joints, wherein the Wirkaxe the tab connection is arranged in the machine center and axially parallel to the plasticizing.
  • the Wirkaxe is preferably arranged at the stator level, in particular below the height of the slide rails. The working area around the plasticizing cylinder is thus free.
  • the individual drive has an electric motor, in particular a servomotor, and a spindle overdrive.
  • the carrier in the area between the upper pivot, the lower hinge point and the chassis stiff with a deformation under load of almost zero.
  • the carrier thus does not give rise to any disturbance due to force effects as a result of changes, eg due to bending, for the direction of the contact pressure, even under the greatest load.
  • the sliding blocks are designed as ball screws, wherein the horizontal distance in relation to the tab connection of the claimed on train sliding shoes is greater than the corresponding distance of the pressure-loaded sliding shoes.
  • the injection unit has, as is known, a drive block for the rotary and the axial movement of the plasticizing screw, which is supported according to the new invention on the carrier and another Gleitschuhinheit on the stand, wherein the plasticizing is firmly connected to the drive block.
  • the injection unit further comprises a further sliding shoe unit with a lower drive bridge, on which the drive block is adjustably supported in the rear part, wherein the support preferably takes place via a pivot.
  • This allows the plasticizing cylinder together with the drive block a slight rotational movement in the manner of a rocker about the pivot as a center of rotation.
  • the aim is to optimally adjust the plasticizing cylinder tip with respect to the mold injection port.
  • the further sliding shoe unit preferably has an adjusting device for vertical as well as for an additional transverse adjustment. This allows the adjustment to be made in both the vertical and horizontal directions.
  • the carrier is arranged with the chassis in the front part and the other sliding block unit in the rear part of the Einsp ⁇ tzvenez, the chassis has four and the Gleitschuhinheit two sliding shoes.
  • the upper pivot pins are arranged at least approximately in a common horizontal plane with the axis of the plasticizing cylinder, such that when adjusting the plasticizing cylinder tip a pivoting movement in both a horizontal and in a vertical plane is feasible.
  • the new invention further relates to a method for setting an injection unit, which is movable with a chassis on sliding machines of the machine stand of an injection molding machine, and a drive unit for axial displacement and pressing the plasticizing cylinder to the injection mold, and is characterized in that the mold tip with the plasticizing cylinder tip is adjusted in case of insufficient centric sealing by means of a rotary movement of the whole injection molding unit both in a vertical and in a horizontal plane prior to production.
