Definitions

  • the present invention relates to a protective element suitable for use with a feeder sleeve product.
  • moulds also known as feeder sleeves
  • Said moulds include sand and various chemicals.
  • the feeder sleeves are exothermic feeding auxiliary materials which are produced at various shapes and sizes by a preforming method, wherein the feeder sleeves are produced from a pre-prepared chemical mixture according to the desired exothermal degree.
  • Patent document no. WO2017007433A1 discloses an exemplary mini riser system which comprises mini riser fixers.
  • the feeding system disclosed in said document comprises a feeder sleeve, a neck piece functioning as a fixer, and a conical piece. With the effect of force applied during the moulding process, said neck piece moves at the vertical axis so as to be driven to the cavity provided within the feeder sleeve.
  • the patent document no. WO2017007433A1 does not mention about a characteristic of the neck piece and the conical piece that enables them to resist to the applied force.
  • said document does not comprise a further protective element between the feeder sleeve and the surface to which the sleeve is fixed in order to provide to protect the feeder sleeve.
  • a protective element suitable for use with at least one mini riser sleeve which comprises a linear cavity through which a fluid material can be passed for the feeding process, at least one outer wall, at least one base, and at least one opening located at the base and providing the cavity to communicate with the outer environment.
  • Said protective element comprises at least one bottom wall suitable for receiving the base of the mini riser sleeve and being made of a more flexible material than the mini riser sleeve; at least one side wall suitable for receiving the outer wall of the mini riser sleeve and being made of a more flexible material than the mini riser sleeve; at least one aperture located at said bottom wall and allowing a fluid passage between the opening and the outer environment.
  • the protective element according to the invention moulding rate and quality of the feeder sleeve are increased by applying it directly on the mould model at the foundries in which high-pressure moulding lines are utilised; and due to the flexible structure of the protective element which is made of a more flexible material than the mini riser sleeve, the mini riser sleeve is prevent from being damaged by the compression effect applied thereon during the moulding process.
  • An object of the present invention is to develop a protective element which provides to reduce the load applied to the feeder sleeve during a moulding process.
  • Another object of the present invention is to develop a protective element which provides to enhance endurance of the feeding element at the position in which it is fixed.

  • Figure 4 is a side sectional view of the protective element in use with a feeder sleeve.
  • mini riser systems In order to provide a quick and quality casting production at the high-pressure automatic moulding lines utilised for mass production of the castings, it is appropriate to use mini riser systems in certain areas on the mould model.
  • a mini riser system which fully functions as a feeder and is able to resist to the mechanical effects on the automatic moulding line.
  • a protective element which prevents the brittle feeder sleeve at the mini riser system from being damaged by the load to which it is subjected during the moulding process.
  • the protective element (E) is suitable for use with at least one mini riser sleeve (1) an exemplary view of which is illustrated in Figure 1 and which comprises a linear cavity (1 a) through which a fluid material can be passed for the feeding process, at least one outer wall (1 b), at least one base (1c), and at least one opening (1 d) located at the base (1 c) and providing the cavity (1a) to communicate with the outer environment.

  • the mini riser sleeve (1) is placed inside said protective element (E). Then, the mini riser sleeve (1) and the protective element (E) are positioned together inside the mould. During compressing the mould, a compression force is created on the mini riser sleeve (1) and the protective element (E).
  • a compression force is created on the mini riser sleeve (1) and the protective element (E).
  • said compression force is absorbed by said protective element (E) by means of forming a friction force between the outer wall (1 b) of the feeder sleeve and the side wall (4) of the protective element (E).
  • the mini riser sleeve (1) is prevented from being damaged by said compression force.
  • the metal in the fluid form during usage of the mini riser sleeve (1) is enabled to be filled to the cavity (1 a) through said opening (1 d) and be removed again when necessary.
  • porosity of said protective element (E) is higher than that of said feeder sleeve (1).
  • the protective element (E) is able to stretch under the compression force.
  • said protective element (E) is produced by vacuum forming production method. Therefore, the production process is able to be performed in a simple and practical way.
  • the protective element (E) according to the invention, moulding rate and quality of the feeder sleeve (1) are increased by applying it directly on the mould model at the foundries in which high-pressure moulding lines are utilised; and due to the flexible structure of the protective element (E) which is made of a more flexible material than the mini riser sleeve (1), the mini riser sleeve (1) is prevent from being damaged by the compression effect applied thereon during the moulding process.
