The sleeve box iron pushing cylinder works to drive the sleeve box loaded with the iron to move on a sleeve box iron circulating roller way, and a lifting hook I of the sleeve box iron mounting mechanism is connected with 1 group of sleeve boxes and iron weights 73 on the sleeve box iron circulating roller way; under the action of the lifting mechanism I, the lifting hook I of the sleeve iron mounting mechanism supports the sleeve hanging lugs of the sleeve to bear the sleeve, and the iron is lowered from the sleeve iron circulating roller way to the same height until the sleeve 74 and the iron 73 are mounted on the sand mold 71; the working cylinder 81 of the molding pouring area works, the sand mold with the sleeve box and the press iron placed thereon moves towards the lifting transition mechanism of the moving vehicle, and the sand mold leaves the lifting hook I of the sleeve box press iron mounting mechanism; the lifting mechanism I works, the lifting hook I of the sleeve iron mounting mechanism ascends to the position of the same height of the sleeve iron circulating roller way, and the lifting hook I ascends to be communicated with the sleeve iron circulating roller way to prepare for the next work. The whole process completes the installation of the sleeve box and the weight.

After the sleeve box and the iron weights on the first condensing area track are connected by the sleeve box iron removing mechanism, the lifting mechanism II works, the lifting hook II of the sleeve box iron removing mechanism supports the hanging lugs of the sleeve box to bear the sleeve box and the iron weights rise from the first condensing area track, the sleeve box and the iron weights are lifted to the height of the sleeve box iron weight circulating roller way, the sleeve box iron weights push the cylinder to work, and the sleeve box and the iron weights are transited to the sleeve box iron weight circulating roller way to run. Under the effect of elevating system II, carry and collude II decline and first condensation line district track intercommunication, repetitive work.

When the box cleaning mechanism 34 and/or the iron-pressing cleaning mechanism 35 work, the iron-pressing lifting hook 334 of the iron-pressing lifting mechanism 33 supports the iron-pressing hanging lugs of the iron pressing, so that a certain height space is kept between the iron pressing and the box; the working cylinder of the box cleaning mechanism works to drive the box cleaning brush to effectively remove residual sand attached to the inner wall of the box; the working cylinder of the iron pressing cleaning mechanism works to drive the iron pressing cleaning brush to effectively remove residual sand attached to the lower surface of the iron pressing.

The casting production line is provided with the box cleaning mechanism and the iron pressing cleaning mechanism, so that residual sand attached to the box and the iron pressing is effectively removed in time respectively, the smooth installation of the follow-up box and the iron pressing and the effect of compacting the sand mold are ensured, and the stable operation of the casting production line is ensured.

The moving vehicle on the casting production line moves according to the molding pouring section moving vehicle running direction F2, the first condensation section moving vehicle running direction F1, the second condensation section moving vehicle running direction F4 and the third condensation section moving vehicle running direction F5, and then circulates to the sand mold molding track through the upper layer line changing mechanism; the removed box weights are moved to the position of the box weight installation mechanism according to the running direction F3 of the box weights on the roller table. The production line is reasonable in arrangement, and is cooled circularly, the whole occupied area of the production line is small, and the factory arrangement and installation are convenient.

The foregoing description is only illustrative of the preferred embodiments of the present invention, and the above-described technical features may be arbitrarily combined to form a plurality of embodiments of the present invention.

While the invention has been described above with reference to the accompanying drawings, it will be apparent that the invention is not limited to the above embodiments, but is capable of being modified or applied to other applications without any modification, as long as the inventive concept and technical scheme are adopted.
