Technical Field
The invention belongs to the technical field of die casting and casting, and particularly relates to an automatic casting die casting method.
Background
At present, the mould casting adopts manual operation of a hydraulic pump switch, steel flow is controlled by a hydraulic cylinder, the size of the steel flow mainly depends on the opening degree of the hydraulic cylinder controlled by an operator according to experience, the operation level is different, and the steel flow is too small in the casting process, so that the molten steel is easy to solidify in a runner brick to cause 'blind'; in the casting process, an operator controls the size of the steel flow by experience, constant-speed casting and casting cannot be guaranteed, and the influence on the quality of steel ingots is large. The instability of casting speed causes the defects of steel ingots such as slag rolling, shrinkage cavity and the like, and the product quality can not be ensured.

The invention solves the problems through the following technical scheme:
an automatic casting molding method comprising the steps of:
s1, compiling corresponding casting modes according to the casting ingot type, the single-disc casting count and the casting time of different steel types at different casting stages, and inputting codes corresponding to the compiled casting modes into a PLC processor;
s2, selecting a casting mode through a corresponding key on a touch screen, clicking an 'automatic casting button', controlling an opening of a proportional valve by a PLC processor, adjusting the position of a hydraulic cylinder through the opening of the proportional valve, and adjusting the position of a sliding plate of a ladle drain nozzle through the position of the hydraulic cylinder, thereby controlling the size of the steel flow.
Furthermore, a manual control mode is arranged on the touch screen, a forward button or a backward button arranged on the touch screen is manually operated in the automatic casting process, and the manual control oil cylinder is finely adjusted by opening or closing at a fixed opening degree of 3mm each time; if the 'forward button' or the 'backward button' is released, the oil cylinder stops running.
Further, in step S1, a 300-series pipe blank, a die casting ingot type of 8.4t, and a single-disc casting count of 5 are selected, and corresponding casting modes are compiled as follows: a. casting the bottom of the mold, adjusting the opening degree of the sliding plate of the ladle drain port to 45% by the PLC through a proportional valve control hydraulic cylinder, and casting for 30 seconds; b. casting the ingot body, adjusting the opening degree of the steel ladle down gate sliding plate to be 38% automatically by the PLC through a proportional valve control hydraulic cylinder, and casting for 12 minutes; c. the PLC processor controls the hydraulic cylinder through a proportional valve to adjust the opening degree of the steel ladle down nozzle sliding plate to be 15% automatically, and the casting of the cap opening is finished; d. the "auto-pour button" is turned off.
Further, the model of the proportional valve is E1-15-2X/G24N9K4/V type proportional valve.
Compared with the prior art, the invention has the beneficial effects that:
