Definitions

  • the present invention relates to a means and method for locating a sand mould and casting in preparation for subsequent operations.
  • the mould and core assembly for a cylinder block is comprised of a multiplicity of sand-type foundry components, or cores, formed from particulate foundry sand, and a binding agent.
  • the core is intended to define the inner walls of a cavity which will ultimately become the crankcase of the cylinder block.
  • a series of external mould components define the outer walls of the cylinder block.
  • Solution treatment consists of heating the metal to a high temperature and holding it there long enough for soluble alloying elements to diffuse evenly throughout the metal in solid solution. Precise temperature control and timing are important for effective solution heat treatment.
  • the solution heat treatment temperature for 319 aluminium alloy, as used for cylinder block production is 495°C (923°F).
  • the casting needs to remain at the solution temperature for a prolonged period, for a cylinder block casting this could be between 4 and 8 hours.
  • the costs associated with maintaining a furnace at this temperature, for these durations is considerable.
  • the portion of the mould removed is the cope.
  • the casting is a cylinder block.
  • the exposed portion is the bulkhead of the cylinder block.
  • the fixture on which the casting is placed is a pallet.
  • the casting is placed on the fixture via manipulation means.
  • the manipulation means is an automated device.
  • the cope is removed within 2 minutes of filling the mould with molten metal.
  • the subsequent operations involve manipulation of the mould and casting via a second automated manipulation means.
  • the second automated manipulation means utilises robots.
  • Figure 1 is an end view of a cylinder block enclosed in its external mould
  • Figure 2 is an end view of the cylinder block as in Figure 1 , with the cope removed; and Figure 3 is an end view of the cylinder block as in Figure 2, positioned via the exposed bulkhead onto the pallet, with the robotic manipulation means poised to perform the required process.
  • a cylinder block 1 enclosed in its external mould, the external mould comprising a cope 2, side cores 3 and 4, a base core 5, and end cores 6 and 7 (not shown in order to permit visibility).
  • the cope 2 is then removed, and the bulkhead 9, of the cylinder block is exposed.
  • the mould and casting are then placed in position on a pallet 8, via the bulkhead 9, fixing the mould and casting in position in preparation for subsequent operations.
  • a pair of robotic arms 10 and 15 both having manipulation means, in this case grippers 20 and 25 respectively, at their ends.
  • a clamping cylinder 30 which is used to secure the cylinder block casting 1 , to the pallet 8.
  • the labyrinth shut-off 40 has inter-engaging male and female portions, 45, and 50, in the base core, and side cores respectively. These labyrinth interfaces are designed to act as a shut off to seal potential run out areas for the molten metal from the mould.
  • the external faces of the cores 3, 4 and 5 have robotic gripper positions 55, 60 and 65 formed into them, to facilitate manipulation by the grippers 20, and 25, of the robotic arms 10 and 15.
  • any manipulation of the mould and casting close to solidus is problematic, not to mention dangerous, due to the amount of residual heat retained in them from the casting process.
  • the method according to the present invention will be of particular benefit to those wishing to utilize automated devices such as robots to handle a freshly poured casting and mould. This method ensures that each mould will be positioned identically before subsequent automated processes can commence. This in turn means that castings are less likely to be damaged by any automated machines uitlised in post pouring processes.

Abstract

L'invention concerne un procédé destiné au positionnement d'un moule en sable contenant un moulage en prévision d'opérations ultérieures. Dans ce procédé, au moins une partie du moule est retirée de façon qu'une partie du moulage soit exposée. Cette partie exposée est utilisée pour positionner avec précision le moulage sur un bâti.
