Abstract
The invention provides a process for casting a black area model of a lost foam, which relates to the technical field of lost foam casting. The process is characterized by comprising the following successive steps of: sand dropping, roll transferring B, empty box returning, box filling A, variable frequency three-dimensional vibration A, box filling B, variable frequency three-dimensional vibration B, buffering, roll transferring A, casting, roll transferring B, cooling, roll transferring B and sand dropping. According to the invention, the technical steps can be continuously implemented in circulation, so that high automation degree and high production efficiency are achieved.
Description
Technical field:
The present invention relates to evaporative pattern placingJi Shu field, specifically a kind of evaporative pattern black area moulding pouring technology.
Background technology:
Technology of EPC is that the foamed plastic model bonding similar to the casting dimension shape is combined into model cluster, after brushing refractory coating and oven dry, be embedded in vibration molding in the dried quartz sand, pour into a mould liquid metals under certain condition, make the model gasification and occupy modal position, solidify the rear method that forms required foundry goods of cooling.For lost foam casting, multiple different call is arranged.Domestic main call has " dry sand cavityless casting ", " vacuum full mold casting ", is called for short the EPC casting.Lost foam casting process comprises white area, black area and yellow district technique, in existing Technology of EPC, in the black area moulding pouring technology, sometimes have the dead time between each processing step, automaticity is lower, cause the efficient of producing low, can not realize uninterrupted cycle operation between the processing step.
Summary of the invention:
Technical problem to be solved by this invention is to provide uninterrupted cycle operation between a kind of realization processing step, the evaporative pattern black area moulding pouring technology that production efficiency is high.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of evaporative pattern black area moulding pouring technology, it is characterized in that: comprise the following steps and carry out successively, knockout, machine roller transhipment B, empty van return, case A, the three-dimensional jolt ramming A of frequency conversion, vanning B, the three-dimensional jolt ramming B of frequency conversion, buffering, machine roller transhipment A, cast, machine roller transhipment B, cooling, machine roller transhipment B, knockout.
Described vanning A, the three-dimensional jolt ramming A of frequency conversion, vanning B, the three-dimensional jolt ramming B of frequency conversion and buffering adopt the control of PLC control system.
The three-dimensional jolt ramming A of described frequency conversion and the three-dimensional jolt ramming B of frequency conversion adopt the plain bumper HYDRAULIC CONTROL SYSTEM.
Cast section vacuum system is adopted in described cast.
The three-dimensional jolt ramming A of described frequency conversion and the three-dimensional jolt ramming B of frequency conversion adopt the raining-type sand filling machine to add sand.
Described cooling comprises two cooling sections arranged side by side.
The invention has the beneficial effects as follows: uninterrupted cycle operation between the processing step of the present invention, automaticity is high, and production efficiency is high.
Description of drawings:
Fig. 1 is process chart of the present invention.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of evaporative pattern black area moulding pouring technology, it is characterized in that: comprise the following steps and carry out successively, knockout, machine roller transhipment B, empty van return, case A, the three-dimensional jolt ramming A of frequency conversion, vanning B, the three-dimensional jolt ramming B of frequency conversion, buffering, machine roller transhipment A, cast, machine roller transhipment B, cooling, machine roller transhipment B, knockout.
Vanning A, the three-dimensional jolt ramming A of frequency conversion, vanning B, the three-dimensional jolt ramming B of frequency conversion and buffering adopt the control of PLC control system.The three-dimensional jolt ramming A of frequency conversion and the three-dimensional jolt ramming B of frequency conversion adopt the plain bumper HYDRAULIC CONTROL SYSTEM.Cast section vacuum system is adopted in cast.The three-dimensional jolt ramming A of frequency conversion and the three-dimensional jolt ramming B of frequency conversion adopt the raining-type sand filling machine to add sand.Cooling comprise two cooling sections arranged side by side.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
