Duplex method lost foam aluminum casting equipment

Abstract

The invention relates to the technical field of lost foam casting, in particular to duplex method lost foam aluminum casting equipment which comprises a base; a supporting plate is fixedly connected to the position, close to the left end, of the outer surface of the upper end of the base; a supporting table is fixedly connected to the position, close to the upper end, of the outer surface of the right end of the supporting plate; and the outer surface of the lower end of the supporting table is fixedly connected with a driving mechanism. The device structure can press and flatten quartz sand, so that the quartz sand makes contact with a casting model more tightly, and the quality of a casting finished product is improved; and besides, a better sealing effect can be provided for a sand box, the sand box is matched with a vacuumizing pipe to work, a good vacuum effect can be achieved in the sand box, the mold filling capacity is improved, and carbon black defects on the surface of a casting can be reduced; quartz sand and the casting in the sand box can be automatically poured out, so that the working efficiency is greatly improved; and multiple functions of casting, pouring out, filtering and collecting can be achieved, so that a large amount of manpower and material resources are saved; and the structure is simple and practicability is high.

Description

technical field [0001] The invention relates to the technical field of lost foam casting, in particular to a dual-process lost foam casting aluminum equipment. Background technique [0002] Lost foam casting (also known as solid casting) is to bond and combine paraffin or foam models similar in size and shape to castings to form a model cluster. After brushing refractory paint and drying, it is buried in dry quartz sand for vibration molding. Down pouring, the model is vaporized, the liquid metal occupies the position of the model, and solidifies and cools to form a new casting method. The lost foam casting is a new process with almost no margin and precise molding. This process does not need to take a mold and has no parting surface. , No sand core, so the casting has no flash, burr and draft angle, and reduces the dimensional error caused by the combination of cores. The surface roughness of castings can reach Ra3.2 to 12.5μm; the dimensional accuracy of castings can reac...

Problems solved by technology

[0003] However, in the existing technology center, the lost foam casting aluminum equipment usually needs to move the entire sand box to another area after the injection molding is completed, and pour out the quartz sand and castings together, which will not only cause a lot of dust during the pouring process The dust phenomenon occurs, which affects the respiratory health of the staff, and it is inconvenient to take the casting, and the quartz sand with impurities needs to be processed in other processes before it can be used again. The manpower and material resources required for the entire process are very large, and the traditional Before casting the lost foam casting aluminum equipment, it is usually necessary to seal the top of the sand box with a plastic bag, and then use the exhaust system to pump out the gas generated inside it in time, so as to reduce the occurrence of pore defects inside the casting, but every time Each processing requires a large amount of film plastic bags, and this plastic bag is easily burned by sparks and melt splashes during the casting process, destroying its sealer, thereby affecting the work of the exhaust system, making the inside of the sand box Can not form a complete vacuum state, which affects the quality of the casting, and the overall needs to be improved
