The biggest die-casting (zinc) weight: Time of circulation of 0.5 kilograms of jobs: 10 / cent 1, abide by " cast installation current operating rules " concerned regulation. 2, still must abide by before the job: The engine oil inside gasoline tank of A, examination is measured, the face that be like oil the upper limit place under the window that inspect oil, 30 machine that should join clean are oily; Electrify of B, electric stove heats, and must be inserted go up thermocouple; C, heat heat preservation is covered; D, by craft requirement warm-up presses mould; E, pressure shoot bracket to connect cooling water, other the cooling water of each place is supplied by need pointwise; Lay aside of F, open presses crock cut down and air to end cut down; G, open pressure to express switch, the oil pump that start, pressure rises reach 63 kilograms / centimeter 2; H, after fusing when alloy, pressure shoot piston immerge alloy to heat, subsequently mount pressing shoots a piston; I, turn programme controll switch to " hand to use " position, the experiment leaves model and combine a model, after affirming the orgnaization is normal, fangke has production. 3, still must abide by in the job: When A, job, cogent attention is safe, handlers must apparel things of good labor insurance, must not stand in the place that reaching nozzle to die-casting cent face to have the job, in case zincic splashing goes out, produce burn accident; B, when beginning die-casting, move " to be operated with " hand first, after it is normal to affirm, ability uses " semi-automatic " or " automatic " works; C, often observe whether all sorts of appearance reading accord with craft requirement, the motion of equipment is normal, discover unusual appearance, should stop " ammonium button urgently to undertake checking by " , inform maintenance technician is repaired when necessary; D, if close,encounter when film have trouble and stop, need to add up to pushbutton of " of modular breakdown restoration by " , make its fly a model, after check and removing trouble, continue to work. E, ask by craft, adjust appropriately heat preservation covers temperature, prevent nozzle knot a place of strategic importance and splash of metallic fluid overheat; The F, temperature rise that often notes hydraulic pressure oil, oil is lukewarm highest must not exceed 55° С , inspect the rate with oily high temperature rise, can adjust appropriately condenser water quantity; Stop doing business of G, equipment when half hours of above, must press instead shoot a piston to tear open, put by crucible heat preservation. Like cease a hour of above is erudite must close pump to jockey, dump, shut lay aside to press crock cut down, prevent generation misoperation and use up lay aside to control crock pressure; Face of fluid of H, metal should often immersion pressing shoots a piston, top limit should be in fluid face under the brim on crucible 20 millimeter; I, to fill inside crucible when adding metallic piece, piece degree cannot pass big, lest metallic temperature is reduced significantly. And piece makings should press craft warm-up, the metal that does not allow to add moisture piece makings, lest produce explosive accident; J, malfunction when electric stove silk is being produced, when mark of occurrence alarm question, must inform maintenance technician instantly, undertake checking repairing; K, equipment produces an accident, answer to stop " pushbutton urgently by " , lay aside involving money presses crock cut down, carry spot condition, sign up for rely on to concern a section, undertake examination, analysis, processing. 4, still must abide by after the job: The metallic fluid of 2/3 stays inside A, crucible, thermocouple can stay in crucible; B, close pump to jockey, and dump; C, shut lay aside to press crock cut down and pressure watch switch; D, shut air to end cut down; E, shut water supply cut down, stop the supply of all cooling water; F, pull down pressure shoot a piston, put in safe place; After G, equipment clears, the athletic section of equipment (the lever that be like a crock, guide bar, slippery course) still need oil of a small machine.
