In sum, the present invention a kind ofly prevents that melt overflows in cast and the return course from pouring ladle, guarantee the basicly stable method and the device thereof that prevent generation overflow in the artificial lead-calcium alloy casting process of cast flow.
Description of drawings
Fig. 1 is that lead-calcium alloy is manually poured into a mould schematic diagram;
Fig. 2 is the lead-calcium alloy running gate system schematic diagram that prevents overflow.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 2, Melt Pump 5 imports are connected with feed tube 6, Melt Pump 5 outlets are provided with outflow tube 4 and dock with tundish 7, tundish 7 is installed on the tundish support 8, the stopper rod 12 of one band conehead is installed on tundish 7, stopper rod 12 drives with cylinder 11 and is connected, cylinder 11 drives stopper rod 12 and opens and closes the head piece that goes out that can block or open tundish 7, the head piece that goes out of tundish 7 is connected with pouring ladle 9, pouring ladle 9 is connected with depositing 10, watering die case 15 is provided with and comprises and begin to water mold 1, mold 2 is watered in the centre, the most last mold 3 that waters is at interior a plurality of molds that water, be provided with starting position switch 13 in the starting end position of watering die case 15, be provided with last position in the clearing end position of watering die case 15 and put switch 14, control system and cylinder 11, starting position switch 13 and last position put switch 14 and Melt Pump 5 is electrically connected.
Operation principle of the present invention:
As shown in Figure 2, the stopper rod 12 of a band conehead is installed on tundish 7, stopper rod 12 drives it by cylinder 11 and opens and closes, and the Lift of stopper rod 12 is determined by the displacement of cylinder 11 pistons, adapts to the needs of different cast flows thus.The displacement of the piston of cylinder 11 can be passed through method controls such as mechanical position limitation, the selection of cylinder stroke.
The principle that prevents casting process generation overflow is as follows: manually touch starting position switch 13, lift, open stopper rod 12 on control system control cylinder 11 pistons, depositing 10 begins cast from beginning to water mold 1, to the most last when watering mold 3, the artificial last position of touching is put switch 14, control system control cylinder 11 pistons-stopper rod are 12 descending, close tundish 7 goes out head piece, manually controls depositing 10 and gets back to the cast starting position and water mold 1 at the beginning, has ensured that thus return course can overflow from pouring ladle 9.The said process circulation is carried out.
