1. Kolanda na ndenge ya sikisiki ndenge ya kosala ba casting ya die .
The temperature of the aluminum water in the holding furnace should be controlled at ±3℃in order to stabilize the stirring temperature. The temperature after stirring must be adjusted according to the chemical composition of each furnace to ensure that the solid phase rate is stable at ±2%. The temperature of the mold must be checked and controlled so that the alloy can be smoothly filled and ordered to solidify. It is necessary to rationally formulate and adjust the process parameters ya masini ya kosala ba casting na tango esengeli, mpe tala ba castings ya die mpo na ko assurer qualité ya ba castings ya die.
2, ba précautions ya fonctionnement ya pulvérisation ya agent de libération .
Pay attention to how much the release agent coating is applied, avoid too much coating, too little or miss the coating. The parts where the castings are difficult to demold can be sprayed with more paint, and the parts that are easily released from the mold are less sprayed. When spraying the paint, use a spray gun to move from top to bottom, so that the water accumulated in the cavity flows from top to bottom, and the excess water is blown out of the cavity. The cavity is easy to stick to the mold part, and the first time is sprayed to cool down, and then sprayed to form a coating film. Do not get too close to the spray to prevent the paint water from flowing in the cavity. After spraying, use air to blow off the excess and accumulated paint in the cavity. In particular, pay attention to the paint in the deep cavity or dead Corner. Esengeli kopumbwa mpo na kopekisa mayi e vaporiser na motango monene ya gaz sima ya molunge, na ndenge ete casting ezali na ba pores. , sous-casting, separation ya malili, mousse, oyo ezali na rôle ya motuya mingi na kosilisa occurrence ya ba pores na ba castings{9}}
3. Bokebisi tango ya kosalela film ya molunge na Machine ya Casting ya Die .
Sima ya kosalela moule ya moto ya masini ya molunge ya moule, tango moule ya moto ebandi, alliage liquide ekoki kosalelama mpo na ko mouler moule ya moto 5-10 moule na vitesse ya moke, mpe na sima alliage semi-solide normal mpe ba paramètres ya casting ya die semi-solide esalelamaka mpo na production ya casting ya die, mpo ete moule ekoki kobatelama. ekoki mpe kopekisa ba matériaux ya flashing{4}}
