Definitions

  • the invention relates to a method for the production and pouring and molding the molds as well as a casting plant for carrying out the process.
  • the molds provided with a molding box are molded in a known manner in a molding machine, this molding machine advantageously having a turntable has a model plate for both the has one as well as the other half of the molding box.
  • the Frame is placed on the model plate and by means of Filled with sand, which is usually one clay-bound sand. After the corresponding one
  • the molding box half of lifted off the model plate and onto a transport track put on.
  • this transport track is a turning device built in, which the mold box halves like turns that the molding plane faces upwards.
  • the core insertion is much easier and on the other hand, the conventionally trained Casting molds for the pouring funnel and the Feeders to be reworked.
  • the one mold box half in a turner then turned and the mold box halves are in a facility for putting the two together Molded box halves joined together. Following this the casting mold is cast in a lying position. After the casting has solidified, it is shaped. The mold box halves are then separated again and fed again to the molding machine.
  • the invention has for its object a method as well as a casting plant for carrying out the process of the type mentioned at the outset to propose which not only enables castings to be made from aluminum, which significantly improved in casting quality are and where it is even with complicated castings it is not necessary to provide additional feeders.
  • the casting plant is designed so that it is inexpensive and can work automatically.
  • This task is for the method with the characteristics of claim 1 and for the casting machine with the features of claim 2 solved.
  • molds provided with mold boxes are used, which are shaped in a conventional manner and provided with cores, which however are so designed are that the pouring funnel as well as the feeder in the molding plane of the mold is arranged.
  • the shape of the casting mold is in carried out lying, but the cast in a standing Way, with such arrangements not only a sufficient volume of feeder can be created, but also a sufficient hydrostatic Receive pressure for the metal to be replenished becomes. This enables even complex aluminum castings, for example engine blocks or cylinder heads, inexpensive to manufacture.
  • Such castings are currently in chemically bound boxless Casting molds made, which are not just an expensive one Condition sand, but also beyond expensive and complicated equipment for the production of many molded parts for the castless mold, which also partly assembled with machines and partly by hand on the other hand in that also the casting is formed with the mold upright.
  • a casting plant according to the invention is conventional System units until the two mold halves are joined built so that here on proven and inexpensive Plant components can be used can.
  • a turning device in the casting mold system built-in which allows the molding box to fit around its Longitudinal axis to turn 90 degrees, so that it is now upright on another, usually a little narrower, Transport track is continued.
  • the casting molds are cast and also unpacking the molds. For this, the The mold remains on the conveyor. You just have to be secured perpendicular to the mold so that then the casting by means of a press plate from the mold frame together with the bound Molding sand can be expressed.
  • the molded boxes can be turned 90 degrees and in a lying position separately and in a known way again prepared that they are fed to the molding machine again can be.
  • An embodiment of the invention is as follows described in more detail with reference to the drawing, the one according to the invention trained automatic molding machine in perspective View shows.
  • the automatic casting machine shown in the drawing 1 has a first transport track 2 on which the mold boxes supplied by a separating device 3 in which the mold boxes are divided into two individual Mold box halves 4,5 are separated.
  • a switched on in a second transport path 6 first Turning device 7, the mold box halves are turned so that their molding division level down shows.
  • the mold box halves (4,5) then become one Forming system (8) fed, which has a rotary table (9), the model plates (10, 11) for the two mold halves wearing.
  • the mold box halves (4,5) deposited over each of the model plates (10, 11), with Sand filled, solidified, then on a third Transport track (12) to be dropped.
  • this Transport track is a second turning device (13) turned on, the mold box halves (4,5) by 180 Degree turns so that the molding level and thus the Mold cavity (14) of the mold boxes (4,5) shows upwards.
  • the third transport path (12) then has a core insertion path (15) in which the cores are in the upward direction showing mold cavities can be inserted in a simple manner are.
  • a mold box half is then turned through 180 degrees, then the mold box halves (4, 5) of an assembly station (17) are fed in a mold box half on the corresponding other mold box half put on and assembled into a mold.
  • the molds are made so that the pouring funnel (22) and the feeder (23) in the division level (24) of the mold (18).
  • the casting of the molds (18) takes place in a casting station (30) on a fifth Transport track (21), this also at the same time forms the cooling section.
  • the mold (18) arrives in a molding station (25), which is driven by a lifting cylinder (27) Press plate (26).
  • Press plate (26) Furthermore fixed the molding station (25) the casting mold (18) vertically to their direction of transport, so that the demolding without removing the mold from the fifth conveyor track (21) can be carried out.
  • a shooting table (28) On the press plate (26) opposite side of the mold is a shooting table (28) provided on which the casting is pushed becomes.
  • the shaping station (25) is a fifth Turning device (29) connected downstream of the molding box again rotates 90 degrees around its longitudinal axis, so that now the further transport and the separation of the two mold box halves (4,5) in the separation station in usual way can be done. The process repeats then as described previously.
  • the main advantage of the molding system according to the invention is that by the standing arrangement the casting molds have a sufficient feed volume during casting with sufficient hydrostatic pressure also for difficult to cast metals, for example Aluminum, can be obtained so that it is now possible is complex castings such as engine blocks or cylinder heads made of aluminum with box-bound To produce casting molds. Through this cast with standing The molding process is also essential for casting molds simplified since the mold is no longer needs to be removed from the conveyor belt but only pushed out the casting laterally is, which is then freely manageable.
