Definitions

  • the invention relates to a casting test mold for particle-added aluminum metal matrix composites, which is positioned horizontally and cast with gravity method.
  • Casting manufacturing method is defined in the literature as the guiding of molten metal by applying gravity or pressure to a mold cavity that has the shape of the part to be obtained and solidification.
  • the casting manufacturing method has several disadvantages. These can be roughly listed as limitations in mechanical properties, porosity, segregations, coarse and inhomogeneous grain structure.
  • casting test molds are used for testing the casting material and performing simulation analysis.
  • the invention which is the subject of the description, aims to provide a casting test mold that makes it possible to analyze the material during the manufacturing of aluminum matrix metal composites, especially containing particulate additives.
  • the bottom filling mold given in the standards is widely used during the sample production stage, especially in laboratory studies carried out with the casting method.
  • the densities of the additive particle materials used in particle- added composite production for example, aluminum matrix particle-added composite production
  • particles accumulate at the bottom of the mold due to the density difference during the use of the bottom filling mold. For this reason, a homogeneous particle distribution cannot be obtained, and due to the accumulation of particles in the lower part of the mold, these additives cannot take place at the expected level in the internal structure of the samples, especially in the middle and upper parts, leading to prevention of the desired mechanical and microstructure properties to be obtained in the produced samples.
  • a casting test mold mentioned in the Chinese patent document numbered CN205217923 (II) was encountered in the literature search.
  • presented test mold was found to contain vertically positioned casting sections. It can be commented as if the materials poured here contain additive particles, these particles would sink to the bottom due to the density difference, and real values cannot be determined in the tests due to microstructural inhomogeneity.
  • the invention is a casting test mold in which the known state of the art is overcome, the disadvantages are eliminated and additionally includes advantages over prior art.
  • the aim of the invention is to present a test mold to be used in the casting test of particle- added aluminum metal matrix composite materials.
  • Another aim of the invention is to present a novel casting test mold, which can be used with the gravity casting principle which is positioned horizontally, to be used in the casting test of particle-added aluminum metal matrix composite materials where the particles are homogeneously dispersed in the casting material and thus the precision of the test results is increased by producing samples with the desired micro and macrostructural properties.
  • the present invention is a test mold to be used in casting tests of particle-added aluminum metal matrix composites, in order to realize all the objectives mentioned above and which will emerge from the detailed description hereafter.
  • Main features are being horizontally positioned to prevent the particles from depositing at the bottom that makes it suitable for filling with the gravity (casting by the effect of gravity) principle, containing at least one pouring cup positioned on the upper surface of the horizontally positioned test mold that allows to perform gravity casting with a casting ladle, containing various number of cavities that simulate the cooling rate of the wheel mold used in production, is filled by molten metal that is poured from pouring cup and enables to obtain samples after solidification.
  • Figure-1 Perspective view of the casting test mold that is subject to the invention.
  • Figure-2 Another perspective view of the casting test mold that is subject to the invention.
  • test mold (10) which is the subject of the invention is explained with examples that will not create any limiting effect, aiming only for a better understanding of the subject.
  • a casting test mold (10) that is positioned horizontally and cast with gravity method is described for aluminum metal matrix composites to be produced using particle additives.
  • the casting test mold (10) which is the subject of the invention and is different from the vertically positioned and bottom-filled standard test molds, is designed as a test mold (10) that is positioned horizontally and filled by gravity. In this way, the particles in the particle- included casting material do not deposit at the bottom of the mold and are homogeneously dispersed into the test mold cavity. As a result, the accuracy and precision of the tests and analyses have been increased.
  • the test mold (10) includes a pouring cup section (11) which the molten material is poured from casting ladles.
  • the molten material poured from the pouring cup (11) flows into the first cavity (12), the second cavity (13), the third cavity (14), the fourth cavity (15) and the fifth cavity (16) separated by partitions (17).
  • the molten material in the cavities (12, 13, 14, 15, 16) solidifies, it can be subjected to simulation analysis and the mechanical properties can be tested.
  • the test molds (10) are used to simulate the wheel casting molds used in production and are designed considering the heat transfer and cooling properties of the relevant parts of the rim mold.
  • the test mold (10) subject to the invention essentially simulates a wheel mold.
  • the first cavity (12) and the fifth cavity (16) in the test mold (10) simulate the outer flange section of the rim mold, the second cavity (13) and the fourth cavity (15) simulate the inner flange section of the rim mold and the third cavity (14) simulate the spokes of the rim.
  • test mold (10) which is the subject of the invention is given in Figure 2. Accordingly, the test mold (10) is positioned horizontally and has the advantage of homogeneously dispersing the particles in the molten casting material. In vertically positioned and bottom-filled standard test molds, the particles in the molten material deposit at the bottom, in which test results are negatively affected and do not reflect the actual condition. In the test mold (10), which is the subject of the invention, the disadvantages of the prior art are eliminated by horizontal positioning. In order to keep the test mold (10) in a horizontal position, the height (a) of the test mold (10) was kept shorter than the length (c) and width (b).
