Definitions

  • the invention relates to a device for the movable mounting of an upper mold according to the preamble of patent claim 1.
  • the upper mold by means of a simple pivoting drive from a closed operating position in which the upper mold and the lower mold are closed and in which a workpiece is produced by injection or molding, in to move an open loading or unloading or maintenance position, in which the upper mold for inserting inserts, for removing the finished workpiece and / or for cleaning the mold pivoted by 180 ° and stored laterally.
  • This wide pivoting movement requires a relatively large amount of time and space.
  • the upper mold is held by a simple pivot drive at a distance above the lower mold.
  • a disadvantage of this configuration is that the space between the molds is very difficult to access, especially for large workpieces.
  • This disadvantage is partially countered by the fact that a second drive in addition to the pivoting movement allows a horizontal displacement of the upper mold.
  • this increases the cost and thus the cost of such a device considerably.
  • the present invention has for its object to provide a device that allows for low Plath collar significantly better accessibility at the same time cost-effective production.
  • the core of the present invention is that the upper mold is pivotally mounted on a frame by means of a four-bar mechanism, so that the pivot path allows a very wide opening of the space between the two molds.
  • the upper mold is articulated by means of a pull rod and a triangular lever to a vertically extending part of the frame.
  • a leg of the triangular lever in conjunction with the drawbar forms a four-bar linkage, wherein at a different corner of the triangular lever, a drive for generating a pivoting movement is articulated.
  • the ratio of load arm to power arm on the triangle lever in about two to one.
  • a relatively large pivoting travel of the upper mold can be achieved.
  • the lower mold is pivotally mounted on the frame.
  • an ergonomically advantageous position for the removal of the workpieces and the cleaning of the mold can be achieved.
  • FIGURE 1 shows a side view of the device according to the invention with the mold open.
  • FIG. 1 shows a device for the movable mounting of a mold with the mold open.
  • the device comprises a frame 1, which is composed of a plate-shaped machine foundation, a pair of cheeks 2 attached vertically thereto, and vertical supports 3 arranged opposite the cheeks 2.
  • a triangular lever 11 is pivotally mounted by means of a bearing 15. This triangular lever 11 is connected at its upper left corner in the region of an articulation 16 with the upper end of a piston rod 17 which belongs to a hydraulic cylinder 18, the lower end near the plate-shaped lower part of the frame 1 in the region of articulation 19 with the cheek second articulated is connected.
  • a tie rod 10 is further articulated in the region of a joint 13, the other end is fixed in the region of a joint 12 to a hinge plate 9 of the upper mold.
  • a hinge plate 9 of the upper mold At this articulation plate 9 and the right outer end of the triangular lever 11 in the region of a joint 14 is attached.
  • the distance of the articulation 16 of the piston rod 17 to the bearing 15 forms the power arm A on the triangle lever 11.
  • the ratio of the power arm A to Lastarm B is preferably about one to two, so that by means of a relatively short actuation travel of the hydraulic cylinder 18, a relatively large pivotal movement of the upper mold is achievable.
  • the upper mold 7 is fixed by means of an upper platen 6 to an upper mold carrier 5, which in turn is flanged to the hinge plate 9.
  • an upper mold carrier 5 designed as a hydraulic cylinder lifting cylinder 29 is arranged, the piston is fixed with its lower end to the platen 6.
  • a lock 4 is provided in the form of a perpendicular to the plane movable bolt, which is brought down in swung-upper mold carrier 5 with a locking bore 8 at the upper end of the supports 3.
  • the entire tool also includes a lower mold 25 which is fixed to a lower platen 20, which in turn is pivotally mounted on the frame 1 by means of a bearing 23.
  • the lower platen 20 is fixed by means of a hydraulic cylinder 21, the lower end by means of a linkage 24 on the frame 1, and the upper end with its extendable piston rod in the region of an articulation 22 on the lower platen 20, from the feed shown in the figure 1 - Or removal and / or maintenance position in an operating position pivotally, in which the lower mold 25 is parallel to the lower plate of the frame 1.
  • a slider control 26 is arranged on the lower molding tool 25, by means of which, if appropriate, slides for producing undercuts on the workpiece can be actuated. Ejectors 27 facilitate the removal of the finished workpiece from the lower mold 25th
  • the mold is opened in the feed or removal and / or maintenance position shown in Figure 1 so far that the operator has unimpeded access.
  • the insertion of inserts and the removal of the finished workpiece can be carried out unhindered by means of a robot.
  • the pivotal movement of the lower mold 25 also facilitates access.
  • the finished workpiece can be removed, the mold can be cleaned if necessary and optionally inserts are inserted for the production of the next workpiece.
  • another multi-link transmission such as a six-bar linkage can also be used advantageously for generating a pivoting movement of the upper mold.
