Definitions

  • the invention relates to foundry, particularly to devices and methods for working of casting molds.
  • the technical task to be solved by the proposed method for working of casting molds with powder lubricant is elimination of existing disadvantages by increasing the quality of working and sustainability of casting molds, automating the mold production steps, as well as developing a device for its implementation.
  • the undertaken task is achieved by the fact that in the method for working of casting molds with powder lubricant is carried out dusting of silicone molds in a closed space, by lapping the powder lubricant to the mold surface with moving brushes, the casting molds being in rotation and powder material feed is metered, is collected the excess lubricant, and the duty cycle, comprising lapping of casting molds with powder lubricant, as well as its feed in the work area are automated and controlled.
  • the device for working of casting molds with powder lubricant according to the proposed method consists of a body with a worktable and a flap cover, under which, on a frame by means of springs are mounted brushes. In the body is mounted a main electric motor, coupled with a brush driving mechanism and a disk swinging
  • a suction fan with a storage tank placed in the body under the worktable; mounted on bearings, a crank shaft, on which are fixed the brushes, and joined with the brush driving mechanism by detachable half-couplings; a vibromechanism for feeding the powder lubricant on the inner surface of the molds, containing an additional electric motor with disbalance and a pull rod joined with several tanks with powder lubricant, placed above the disks, and also comprises a device duty cycle control unit.
  • the technical result of this invention consists in improving the quality of casting mold working with powder lubricant, in increasing the service life of molds, automating the technological process, as well as increasing the productivity and improving the working conditions.
  • FIG. 1 general view of the working device
  • FIG. 2 side view of the device
  • the device for working of casting molds with powder lubricant consists of a body 1 with a worktable 2 and a flap cover 3.
  • a main electric motor 4 transmitting the torque to a brush 6, 6' driving mechanism 5 and a disk 8, 8' swinging mechanism 7, on which are mounted the casting molds with the cavity open upwards, at the same time the working surface of the disks 8, 8' is made with increased
  • a suction fan 9 with a storage tank 10 for the accumulation of excess powder lubricant, placed in the body 1 under the worktable 2.
  • the brushes 6, 6' are mounted on a frame 11 suspended under the flap cover 3 by means of springs 12 and connected to a crank shaft 13.
  • the crank shaft 13 is mounted on bearings 14, 15 and connected to the brush 6, 6' driving mechanism by detachable half-couplings 16, 17.
  • Under the flap cover 3 is also located a powder lubricant feeding vibromechanism, consisting of an additional electric motor 18 with disbalance and a pull rod 19 connected to several tanks 20, 21 with powder lubricant, located above the disks 8, 8'.
  • a control unit (not shown) that controls and
  • the control unit coordinates all the operating modes of the device, including the time cycle of rotation of the main motor 4, of operation of the suction fan 9, time cycle of feed, as well as the amount of powder lubricant feed from the tanks 20, 21 , through the control of the mode of operation of the additional electric motor 18.
  • the device for working of casting molds with powder lubricant works as follows: Before beginning the technological process of working rubber (silicone) molds with powder lubricant, the tanks 20, 21 are charged with talc, graphite or similar powder lubricant.
  • the casting rubber (silicone) half-molds are mounted on the disks 8, 8' with the open cavity upwards. When lowering the flap cover 3, the brushes 6, 6' enter the cavities of casting half-molds, the half-couplings 16, 17 engage into mesh, and the limit switch (not shown) turns on the electric power supply circuit. It is switched on the main electric motor 4, from which the torque is transmitted to a brush 6, 6' driving
