Abstract
The invention provides a process method for casting multiple evaporative molds in series in one box, which comprises the following steps: (1) a plurality of pouring channels are made in advance, the pouring channels are respectively connected with the model, the straight pouring channels of adjacent pouring channels are connected through a cross pouring channel, and the cross pouring channel forms an inclination angle of 8-20 degrees with the horizontal direction; (2) boxing and modeling, and compacting the sand mold; attaching a plastic film on the sand mold; (3) vacuumizing and pouring: pouring is carried out from a pouring gate of a pouring channel of one model, and molten iron is poured to each model from a communicating cross pouring channel. The invention realizes series pouring through the communication of the cross runners, and only needs to carry out pouring of a plurality of pieces in one box from one pouring gate, the pouring speed is high, the pouring speed is improved by more than one time compared with the existing pouring method, the plastic film is damaged only near one straight runner, meanwhile, the temperature of molten iron is slowly reduced, the pouring quality is good, and the rejection rate of pouring is low.
Description
Technical field
The present invention relates to the lost foam casting field, especially the process of multiple lost moulds in one box cast.
Background technology
In disappearance mould casting process, should consider that poring rate is fast, the negative pressure of consideration cast completion back sandbox can not destroyed negative pressure because of the temperature of molten iron again, usually adopt a sandbox to arrange that a plurality of foundry goods pour into a mould, this method, the running channel of each foundry goods is independently, needs repeatedly cast, and speed is slow; Easily because of high temperature liquid iron destroys the plastic sheeting that covers, influence the negative pressure in the case, thereby influence casting quality near the sprue.
Summary of the invention
The present invention proposes the process of series pouring multiple lost moulds in one box, what reach is should poring rate fast, after considering again simultaneously to pour, does not have high temperature liquid iron that the plastic sheeting that covers is destroyed near the straight way, influence the interior negative pressure of case.
Technical scheme of the present invention is: the process of series pouring multiple lost moulds in one box, the steps include: that (1) do a lot of running channel in advance, a plurality of running channels are connected with model respectively, connect by cross gate between the sprue of adjacent running channel, cross gate and horizontal direction are 8～20 ° angle of inclination; (2), the vanning moulding, the jolt ramming sand mold; And on sand mold attached plastic sheeting; (3), vacuumize cast: pour into a mould from the cast gate of the running channel of a model, molten iron is poured into each model from the cross gate that is communicated with.
Beneficial effect: the present invention realizes series pouring by the connection of cross gate, only need to carry out one case many cast from a cast gate, poring rate is fast, poring rate is enhanced about more than once than existing pouring procedure, only near a sprue, the plastic sheeting breakoff phenomenon is arranged, the temperature of molten iron descends slowly simultaneously, and casting quality is good, and the percent defective of cast is low.
Description of drawings
Fig. 1 is a kind of embodiment schematic diagram of the present invention.
The specific embodiment
Be a kind of embodiment of the present invention as shown in Figure 1, the steps include: that (1) carry out four running channels in advance, four running channels are connected with model 11 respectively, connect by cross gate 4 between the sprue 3 of adjacent running channel, cross gate 4 is 8～20 ° angle of inclination with horizontal direction; (2), sandbox bottom is provided with pumping chamber, sets gradually stephanoporate steel plate 9, fine sand net 8, coarse sand net 7 on the pumping chamber from bottom to top, sand 2 is contained on the coarse sand net 7, vanning moulding, jolt ramming sand mold; And on sand mold attached plastic sheeting 5; (3), vacuumize cast: vacuumize from bleeding point 10, pour into a mould from the cast gate 6 of the running channel of a model, molten iron is poured into each model from the cross gate that is communicated with.
Shown in Figure 1 is one case four series pouring, the present invention be not limited to one the case four, can be that more multi-model is arranged in three or one case in one case two or one case.
Claims (1)
1, the process of series pouring multiple lost moulds in one box, the steps include: that (1) do a lot of running channel in advance, a plurality of running channels are connected with model respectively, connect by cross gate between the sprue of adjacent running channel, cross gate and horizontal direction are 8～20 ° angle of inclination; (2), the vanning moulding, the jolt ramming sand mold; And on sand mold attached plastic sheeting; (3), vacuumize cast: pour into a mould from the cast gate of the running channel of a model, molten iron is poured into each model from the cross gate that is communicated with.
