Description

Изобретение относитс к литейном производству, точнее к оборудованию дл изготовлени оболочковых форм.The invention relates to a foundry industry, more specifically to equipment for the manufacture of shell molds.

При изготовлении оболочковых полуформ гравитационньом способом, имеют щим наибольшее распространение благодар относительной простоте оснастки и оборудовани , тыльна сторона полуформ не калибруетс , поэтому даже на ее плоских част х имеютс всевозможные выступы, впадины, наросты . При механизированном производстве оболочковых форм это вл етс серьезным недостатком, так как отсутствуют поверхности дл базировани при транспортировке и установ-ке полуформ.In the manufacture of shell half-molds by the gravitational method, which is the most widespread due to the relative simplicity of the rigging and equipment, the back side of the half-molds is not calibrated, so even on its flat parts there are all sorts of protrusions, depressions, growths. In the case of mechanized production of shell molds, this is a serious drawback, since there are no surfaces to be placed during transportation and installation of the half-molds.

С целью формировани плоских опорных поверхностей на тыльной стороне полуформ машины дл изготовлени полуформ снабжаютс специальными устройствами.In order to form flat bearing surfaces on the back side of the mold halves, machines for the manufacturing of mold halves are supplied with special devices.

Известна машина дл изготовлени оболочковых полуформ, содержаща устройство дл формировани полуформ, приводную печь дл отверждени полуформ и устройство с приспособлением дл формировани плоских опорных поверхностей на тыльной стороне полу форм 1 .A known machine for making shell molds comprising a device for forming the molds, a driving furnace for curing the molds and a device with a device for forming flat bearing surfaces on the back side of the molds 1.

Недостатком описываемой машины вл етс усложнение ее конструкции и увеличение габаритов за счет установки специального устройства, работающего в цикле машины, и наличи .специальной позиции машины дл получени опорных поверхностей полуформ.The disadvantage of the described machine is the complication of its design and increase in size due to the installation of a special device operating in the machine cycle and the special position of the machine for obtaining the supporting surfaces of the half-molds.

Целью изобретени вл етс упрощение конструкции машины.The aim of the invention is to simplify the design of the machine.

Дл достижени цели в машине дл изготовлени оболочковых полуформ, содержащей устройство дл формировани полуформ, печь дл отверждени To achieve the goal in a machine for the manufacture of shell half-molds containing a device for forming half-molds, a furnace for curing

15 полуформ, имеющую привод дл возвратно-поступательного перемещени в вертикальной плоскости, приспособление дл формировани плоских опорных поверхностей на тыльной стороне по20 луформ, приспособление дл формировани плоских опорных поверхностей на тыльной стороне полуформ выполнено в виде планок, закрепленных на обращенной к полуформе стороне вьпие25 указанной печи.15 half-molds, having a drive for reciprocating movement in a vertical plane, a device for forming flat bearing surfaces on the back side of 20 shapes, a device for forming flat support surfaces on the back side of half-molds, is made in the form of slats fixed on the side of the specified furnace facing the half-form 25 .

30 shows a four cognitive carousel for making shell half-molds. The machine contains a rotary platform 2 assembly frame on which Model Kits 3 are installed, a device for forming half-molds 4, including a molding hopper 5, -and heating devices b located under platform 2 below the model sets 3. Opening half-molds 4 is carried out in a lifting furnace 7, moved by the drive 8. In a specific embodiment, the machine has a lifting furnace 9 for additional heating of model sets 3 from the working surface. The model set 3 comprises a housing 10, a base plate 11, a model 12, a plate. 13 pillars 14 and limiting plates 15. A furnace is mounted on the furnace 7 to form flat bearing surfaces on the back side of the half-mold 4, made in the form of strips 17 mounted on the side 18 of the furnace 7 facing the model 12. The machine works as follows. the arrival of the mold half 4 to the position of curing (furnace position 7), the furnace 7 is lowered by means of the actuator 8 with the strips 17 into the restrictive strips 15 of the model complex 3. As the mold 4 has not yet hardened, the furnace weight 7 molds the mold 4 and form on its back side 16 are flat supporting surfaces calibrated. heights equal to the height of the limiting bars 15. The dimensions and location of the supporting surfaces are determined by the size and location of the bars 17. The use of the proposed machine thus provides for the formation of flat supporting surfaces on the back side of the shell half-form without complication and with little or no increase in the cost of the machine. The invention can be used on machines having lifting furnaces for curing half-molds. Claims An apparatus for making shell half-molds, comprising a device for forming half-molds, a furnace: for curing half-molds, having a drive for reciprocating movement in a vertical plane, a device for forming flat bearing surfaces on the back side of half-molds, characterized in in order to simplify the construction of the machine, the device for forming flat bearing surfaces on the back side of the half-molds is made in the form of slats fixed on facing on the side of the furnace above.
