[0004] Due to the light weight of the lost foam, when it is placed in the paint bucket, the lost foam will float on the paint. In the existing process, many manufacturers are still using the method of manual painting, which is easy to miss and complicated. The corners or potholes of the parts are easy to accumulate paint, which needs to be cleaned manually, which is a heavy workload and labor-intensive

The invention discloses a lost-foam dip-coating device for a cylinder cover of a diesel engine. The lost-foam dip-coating device comprises a coating box, and a feeding system arranged at the right side of the coating box, wherein the feeding system comprises a feeding drum arranged on the outer side wall of the coating box; a first motor is arranged at the bottom part of the feeding drum; the output end of the first motor is fixedly connected with a first rotary shaft arranged in the feeding drum; a spiral blade is arranged on the first rotary shaft; a feeding pipe communicated with the coating box is arranged at the bottom part of the feeding drum. The lost-foam dip-coating device disclosed by the invention has the beneficial effects that the design is ingenious; by arrangement of the crankshaft, a left down-pressing part and a right down-pressing part, repeated down-pressing action can be carried out on a mold, so that the mold is wholly immersed in a coating barrel; a spring is arranged at the bottom part of the coating barrel, so that when the left down-pressing part and the down-pressing part carry out down-pressing action on the mold, the coating barrel can sway and the moldcan be further soaked and brushed.
Description
Technical field: [0001] The invention relates to the field of casting production, in particular to a lost foam dip coating device for a cylinder head of a diesel engine. Background technique: [0002] In the field of casting processing, lost foam casting technology, as an advanced casting forming method, has developed rapidly in the world in recent years, especially in the automobile manufacturing industry, and can be widely used in the production of non-ferrous and ferrous metal power system parts , Such as cylinder block, cylinder head, crankshaft, gearbox, intake pipe, exhaust pipe and brake hub and other castings. [0003] Lost foam casting is to bond and combine paraffin or foam models similar in size and shape to castings to form model clusters, paint refractory materials and dry them, bury them in dry quartz sand for vibration modeling, and pour them under negative pressure to make the models gasify , the casting method in which liquid metal occupies the position of ...
