Definitions

  • the present invention relates to a device for removing sand from a molding (workpiece) by vibration which vibrates a molding (workpiece) molded by casting such as an auto part to thereby remove sand remaining on the workpiece, in particular, core sand remaining in a hollow portion of the workpiece. More particularly, it relates to a device for removing sand from a workpiece by vibration which holds a workpiece that is to have sand removed against a vibration plate, and vibrates the vibration plate by means of a single vibration motor, thereby removing sand remaining on the workpiece.
  • each of these conventional devices is of a type which removes sand remaining on a workpiece by striking the workpiece with a hammer, and accordingly, has not only a problem that its size is large but also creates environmental pollution problems of noise and scattering of sand which are caused by the hammering.

  • Patent Document 4 Japanese Patent Application No. 2004-243 118
  • the problem to be solved by the present invention is to provide a device for removing sand by vibration which effects removal of sand from a workpiece by vibrating the workpiece characteristically using a single vibration motor instead of a conventional technique for removing sand by striking a workpiece with a hammer, thereby realizing, as a matter of course, size reduction, and being capable of eliminating noise caused by hammering and of preventing environmental pollution due to scattering sand caused by the hammering and further capable of solving the problems inherent in cases where two motors are used, and accordingly, which is so improved as to be capable of solving the drawbacks inherent in the conventional techniques.
  • a device for removing sand from a molding by vibration which device is adapted to remove sand remaining on the molding by vibration, the device for removing sand by vibration comprising:
  • the above-described present invention is so constructed that a workpiece from which sand is to be removed is held against a vibration plate, and the vibration plate is vibrated by means of a single vibration motor to thereby remove sand remaining on the workpiece, in particular, core sand in a hollow portion. Accordingly, the device of the present invention requires no large constituent such as a hammering chamber as in a conventional technique and thus enables size reduction to be realized, and is free from noise caused by hammering, and causes no environmental pollution due to scattering of sand.
  • the device of the present invention is provided with only one vibration motor, it enables size reduction to be realized and is economically advantageous.
  • the two motors are required to rotate synchronously, and accordingly, it is necessary to precisely set proportions of weights of the two motors and positions of elastic support members.
  • the device provided with the single motor is free from such a restriction.
  • Fig. 1 is a plan view of an embodiment of the device for removing sand by vibration according to the present invention.
  • Fig. 2 is a side view of the embodiment of the device.
  • Fig. 3 is a perspective view of the embodiment of the device.
  • the present invention discloses a device A for removing sand from a molding (workpiece) 1 by vibration which removes core sand from a hollow portion 2 of the molding (workpiece) 1 by vibration, and which comprises a base 3 and a vibration plate 5 mounted thereon via elastic support members 4.
  • a workpiece holder 6 for holding the molding 1 therebetween is provided on the vibration plate 5.
  • the vibration plate 5 is connected to a single vibration motor 7.
  • the elastic support members 4 which isolate vibration toward a floor and prevent hindrance of vibration transmission to the vibration plate 5, there may be mentioned rubber supports, metal springs, pneumatic springs and the like.
  • the workpiece 1 is placed in the space formed by the discharge of air, and then air is introduced into the workpiece holder 6 to inflate the workpiece holder 6, thereby pressing the workpiece 1 with pressing means 10 provided at the tip of the clamp rod 9 to hold the workpiece 1 with the workpiece holder 6, as shown in Fig. 5 .
  • the single vibration motor 7 connected to the vibration plate 5 is actuated to vibrate the vibration plate 5, thereby applying vibration to the workpiece 1 to remove sand remaining on the workpiece 1, in particular, core sand in the hollow portion 2.
  • the removal can be effected efficiently.
  • the above-described present invention is so constructed that a workpiece 1 from which sand is to be removed is held against a vibration plate 5, and the vibration plate 5 is vibrated by means of a single vibration motor 7 to thereby remove sand remaining on the workpiece 1, in particular, core sand in a hollow portion 2. Accordingly, the device of the present invention requires no large constituent as in a conventional technique such as a hammering chamber and thus enables size reduction to be realized, and is free from noise caused by hammering, and causes no environmental pollution problem due to scattering of sand.
  • the device of the present invention is provided with only one vibration motor for vibrating the vibration plate, it is economically advantageous and has a simplified structure and enables size reduction to be realized.
  • the device of the present invention is provided with only one motor.
  • the two motors are required to rotate synchronously, and accordingly, it is necessary to precisely set proportions of weights of the two motors and positions of elastic support members.
  • the device provided with the single motor is free from such a restriction. Accordingly, the device for removing sand by vibration according to the present invention has high potential that it will be used widely in the field of casting technique.
