Definitions

  • the invention relates to the production of cast workpieces with at least partially cast inserts in the mold casting process as well as a device for such Manufacturing.
  • each insert is usually in half of the mold, which is split and opened used.
  • the guide length or Insertion depth of the insert within the mold half usually not sufficient for exact centering and in addition, the insert can be particularly during Shift the casting process inside the mold. from that there is often an inaccurate positioning of the insert within the finished cast workpiece, making this often becomes unusable.
  • the resulting object of the invention is an apparatus and a method for manufacturing to specify a cast workpiece with a cast-in insert, both inserting the insert into the Mold as well as the possibility of centering the insert to be improved within the mold.
  • the device consists of a mold, which consists of at least there are two separate mold elements, which ultimately determine the shape of the cast workpiece.
  • Each of the Mold elements have a guide opening in which a slidably arranged stamp is stored. After this Inserting the insert into a mold element arranged guide opening of the total open The mold becomes the insert when the mold is closed held by at least two stamps and can be shifted the stamp inside their guide openings exactly positioned and centered in the mold. The The stamp can be moved within the guide openings enables easy insertion of the insert into one the mold elements with sufficient guide length inside the guide opening.
  • the device has at least two stamps, the with their associated guide openings an axis are arranged, which is also the direction of movement the stamp determines.
  • the stamps preferably the same cross section as that in the Guide opening inserted guide section of the insert. More details on how to run the whole Devices are mentioned in the subclaims 2 to 4.
  • a procedure for Production of a cast workpiece with a cast-in insert in mold casting for protection using a device described above sees a divided mold in front with at least two mold elements, being in one of the mold elements with the mold open the insert with sufficient guide length its guide section into a correspondingly shaped guide opening the mold element is inserted.
  • the stop for the insert acts within the guide opening recessed movable stamp.
  • the within another guide opening of another mold element is slidably mounted in the direction of Inserted part moved and brought into contact with this. The insert part thus fixed between the two stamps can now be positioned exactly inside the mold and be centered.
  • the mold is filled with the casting material.
  • the insert in its final position within the mold at least two guide sections in associated guide openings the mold elements. This allows the insert even with a small insertion depth within the guide openings be securely fixed inside the mold.
  • the device according to the invention and the associated method for the production of a cast workpiece with cast-in Insert is general for cast workpieces of any material and whatever application is applicable. Likewise the device and the manufacturing process are independent on the shape of the cast workpiece or the insert. This is the explanation of the invention Device and the manufacturing process based on a cast Brake housing with associated casting device as pure exemplary to understand.
  • Fig. 1 is a general example of a cast workpiece poured insert part of a brake housing 1 with at least partially cast in metal bolt 2.
  • the brake housing part 1 shown is a component a fixed caliper brake, the edge of a not shown Brake disc protrudes axially and on both sides of the brake disc arranged brake shoes receives. They are not there Brake shoes shown axially within a lining shaft 3 slidably housed and in the circumferential direction to the cast metal bolt 2 supported.
  • the support of the Brake shoes in the circumferential direction is used to transmit the Braking circumferential forces starting from the brake shoes on the Brake housing 1, which is mounted fixed to the vehicle.
  • the cast in Metal bolts 2 are due to the size of the brake peripheral forces exposed to considerable material stress and accordingly require selection of a suitable one and resistant material.
  • the actual Cast material of the brake housing 1 particularly in the case of lightweight designs (e.g. aluminum or aluminum alloys) such high loads on the pad support stood and thus requires the insertion or pouring of resistant inserts made of a highly durable Material.
  • To realize the exact positioning and centering the metal bolt 2 within the brake housing 1 becomes the metal bolt 2 or generally the insert within the split mold or mold from held at least two stamps 4.5, each inside a mold element are slidably guided and in Fig. 1 are also hinted at.
  • the casting device 6 with associated manufacturing process relates to die casting Cast workpieces 1 with at least partially cast Inserts 2.
  • the mold or mold 7 divided and consists of at least two Mold elements 8.9.
  • the two mold elements which are also used as lower box 8 and Upper box 9 are called open.
  • the metal bolt 2 with its guide section 10 in an associated guide opening 11 within the lower box 8 inserted.
  • the insertion depth or guide length of the metal bolt 2 inside the guide opening 11 displaceable within the guide opening 11 arranged stamp 4 limited.
  • the metal bolt 2 is up to inserted into the guide opening 11 to the stop on the punch 4 and therefore has sufficient insertion depth a secure hold in the lower box 8. Then the Lower box 8 and upper box 9 existing mold according to FIG. 2b closed and then top box and bottom box 8.9 centered on each other (see Fig. 2c). Doing so the metal bolt received within the guide opening 11 2 with its opposite, inside the Mold 7 protruding end just not from the top box 9 touches. When centering of top box is complete 9 and sub-box 8 becomes a second stamp 5, the inside the upper box 9 in a corresponding guide opening 11 towards the interior of the mold as far as it will go moved on the metal bolt 2. This is the metal bolt 2 or generally the insert between the stamps 4.5 fixed.
  • the insert 2 initially opposite the punches 4, 5 to center.
  • This can be achieved in a simple manner be that the stamp 5 in the top box 9, for example has cylindrical centering opening in the an associated paragraph of the insert 2 engages.
  • the stamps 5 with a larger cross section as the associated guide section 10 of the insert executed and can embrace it, whereas the other stamp 4 has the same cross section as that Has guide section 10 of the insert 2.
  • the after Fig. 2d between the two stamps 4.5 fixed metal bolts 2 can now 4.5 by moving the two stamp in the axial direction 12 to its desired end position within the mold 7 are brought.
  • the two guide openings are advantageous 11 within the mold elements 8.9 and the associated punches 4, 5 are arranged on a single axis, which also the direction of movement 12 of the marks two stamps 4,5.
  • the end position of the bolt 2 within the Mold 7 to be dimensioned such that the metal bolt to be cast 2 with at least two guide sections 10 inside correspondingly designed guide openings 11 in the mold elements 8.9 is added to hold securely to ensure the mold.
  • the inclusion of the metal bolt 2 on at least two sections 10 within the mold 7 allows very small insertion depths of the insert 2 within the mold 7, which gives the possibility an insert 2 almost completely depending on the application to cast with cast material. Only with a more precise center Positioning of the insert 2 within the mold 7 the interior of the mold is then filled with cast material.
  • the crucial point of the invention is at least two are displaceable within the respective mold elements 8, 9 arranged stamps 4.5, which is initially a comfortable Inserting the insert 2 into a part of the Allow mold 7 and moreover when closed Chill mold 7 through a joint, coordinated shift Insert 2 in its exact final position within the Chill mold and thus also within the finished cast workpiece bring.
  • stamps 4.5 are initially a comfortable Inserting the insert 2 into a part of the Allow mold 7 and moreover when closed Chill mold 7 through a joint, coordinated shift Insert 2 in its exact final position within the Chill mold and thus also within the finished cast workpiece bring.
  • stamps 4.5 is initially a comfortable Inserting the insert 2 into a part of the Allow mold 7 and moreover when closed Chill mold 7 through a joint, coordinated shift Insert 2 in its exact final position within the Chill mold and thus also within the finished cast workpiece bring.
  • stamp movement advantageously electronically, the actuation of the stamp movement being electrical, can be done hydraulically or mechanically.
