Definitions

  • Casting chambers are primarily used in die casting machines for die casting metals such as aluminum, magnesium and brass.
  • horizontal casting chambers are used, which are used horizontally in operation and whose shell body has at its one, machine-side end at the top of a Gussmaterialein colllö réelle and at its other, form-side end a central, axial Gussmaterialauslassö réelle.
  • the casting chambers are exposed to high thermal and mechanical loads.
  • the Gußmaterialein colllötician reaches temperatures of significantly more than 600 ° C.
  • iron atoms may diffuse out of the surface of the casting chamber, causing it to become brittle and flake off, causing scouring, which may impede the sliding movement of a pressure piston in the casting chamber and expose the pressure piston to increased wear.
  • hot casting material filled in by the pouring material filling opening always makes use of the gravitational force to strike its inner surface in the respectively underlying area of the interior of the exchangeable bushing.
  • the invention is therefore an object of the invention to provide a horizontal casting chamber and a method for die casting of metal in such a horizontal casting chamber, by which it is possible to increase the life of the horizontal casting chamber.
  • this object is achieved in that fastening means or fastening means and positioning means are provided, by means of which the removable bushing can be positioned and secured in a plurality of defined, about the central axis against each other twisted mounting positions on the body.
  • the invention is achieved in a method for die casting of metal of the type mentioned in that the exchange bushing detached from the body, relative to this rotated about the central axis in a new mounting position and in this again fluid-tightly and releasably connected to the body becomes.
  • the invention is thus based on the consideration, the casting chamber in such a way that the removable sleeve can be mounted in different angular positions on the body.
  • the change bushing can be solved in a simple manner from the base body, rotated about the central axis in a different mounting position and in this again attached to the base body. In the new mounting position, the bottom area of the exchangeable sleeve then lying down is not or only slightly washed out.
  • the exchangeable sleeve can be brought into different fastening positions relative to the main body, in which case at least different regions of the inner surface of the exchangeable sleeve form the bottom region thereof, which is hit by the hot casting material filled through the casting material filling opening.
  • the replacement intervals for the exchangeable bushing and / or a wear bushing located in the replaceable bush are lengthened.
  • the exchangeable sleeve of the horizontal casting chamber according to the invention can be positioned and fixed in a neutral position on the base body such that the Gussmaterialein colllö réelle is located at the top of the casting chamber and in particular is vertically aligned, wherein the exchangeable sleeve is preferably positionable and fixable in two further attachment positions on the base body, which are rotated relative to the neutral position in a clockwise and counterclockwise direction, so that the Gussmaterialein spallö founded in each of these two attachment positions obliquely upwards.
  • the hot casting material can be filled particularly conveniently into the casting chamber by utilizing the force of gravity.
  • the attachment positions are offset by equal angles to each other, wherein the angle between two adjacent attachment positions is in particular between 30 ° and 60 °, and preferably 45 °.
  • Such an angular offset is particularly advantageous when a mounting position is defined in which the Gussmaterialein colllö Anlagen is vertically aligned. Because in another mounting position, which is adjacent to the aforementioned and offset by an angle of 45 °, such an angle ensures that hot casting material can easily flow into the casting chamber by utilizing the gravitational force.
  • an angle of 45 ° is large enough so that the places where the casting material impinges on the inner surface, far enough from each other lie away and thus the most uniform possible stress on the inner surface is ensured.
  • the exchangeable sleeve and the base body are screwed together and positioned by the screw in the different mounting positions.
  • through holes are provided in the replaceable bushing, which pass through the exchangeable bushing axially between their end faces, and are formed in the end face of the body to the through holes corresponding threaded holes through which the replaceable bushing and the main body can be screwed by means of fastening screws in the different mounting positions.
  • the threaded holes are preferably blind holes.
  • the through bores and / or the threaded holes can be arranged with uniform offset along the circumference of the jacket body, wherein in the region of Gussmaterialein colllö réelle no through hole is present and wherein the angular offset between the through holes in particular between 30 ° and 60 ° and is preferably 45 °.
  • a uniform offset of the holes allows each two adjacent, defined mounting positions are rotated by the same angle to each other. Therefore, it makes sense not to provide a through hole in the region of the Gussmaterialein spallö réelle because such and / or possibly inserted into this fastening screw would hinder the pouring of the casting material in the casting chamber.
  • At least one inlet and at least one outlet of a tempering system is formed on the base body, in particular in the immediate vicinity of a transition region between the base body and the exchangeable sleeve, wherein the inlets and outlets extend in particular in a radial direction of the shell body and with at least one in the wall of the jacket body extending coolant channel are fluidly connected. Since during operation of a casting chamber different areas thereof are heated to different degrees by the hot casting material, the temperature in the casting chamber can be adjusted and kept constant by means of a tempering system. By cooling a region below or opposite the Gussmaterialein colllö Anlagen Eisen embrittled the material of the casting less and leaching is counteracted or their formation is delayed.
  • the Gussmaterialein spallötician is funnel-shaped, with its cross-section decreases towards the interior of the sheath body out. This facilitates the filling of the casting material.
  • the sheath body substantially in the form of a hollow cylinder, in particular wherein the inner diameter is about 120 mm and / or its outer diameter is about 280 to 360 mm and / or the total length is about 815 mm and / or the length of the interchangeable bushing about 320 mm is.
  • a filling aid is preferably inserted into the casting material filling opening.
  • the filling aid may be a funnel, which is preferably designed in such a way that the funnel inlet opening points vertically upwards when the funnel is inserted into a casting material filling opening of the exchangeable bushing pointing only obliquely upwards.
  • the outer contour of the funnel is preferred to the The contour of the pouring material filling opening is adjusted so that the funnel completely closes the pouring material filling opening.
  • a casting chamber which has an increased service life compared to the previously known horizontal casting chambers.
  • the method described above makes it possible to significantly increase the service life of a horizontal casting chamber.
  • FIGS. 1 to 5 show different views of a horizontal casting chamber 1 according to the invention for the die casting of metal according to an embodiment of the present invention.
  • the casting chamber 1 has an elongated, a central axis A defining shell body 2.
  • this has substantially the shape of a hollow cylinder, in which case the inner diameter is about 120 mm, the outer diameter is in large parts about 280 mm and whose total length is about 815 mm.
  • the sheath body 2 has at its machine-side end 3 a funnel-shaped Gussmaterialein colllö réelle 4, the cross-section of which reduces towards the interior of the sheath body 2, and at its mold-side end 5 a central, axial Gussmaterialauslassö réelle 6.
  • the sheath body 2 is divided along the central axis A in a Gussmaterialauslassö réelle 6 comprehensive body 7 and the Gussmaterialein colllö réelle 4 comprehensive exchange bushing 8, wherein the length of the exchangeable sleeve 8 with about 320 mm is slightly more than a third of the total length of the sheath body 2.
  • the main body 7 and the exchangeable sleeve 8 are at their to each other assigning ends 9, 10 fluid-tight and releasably connected to each other.
  • fastening means by means of which the exchangeable sleeve 8 can be positioned and fastened in a plurality of defined, about the central axis A against each other twisted mounting positions on the base body 7, such as in the FIGS. 6 to 8 is shown.
