Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

As shown in fig. 1, an aluminum alloy continuous casting forming device comprises a machine body, a slide block connected to the machine body in a vertical sliding manner, a driving mechanism for driving the slide block to slide, an upper die 1 fixed at the bottom of the slide block, and a lower die 2 arranged on a workbench of the machine body;

referring to fig. 1 and 2, a water tank 3 is arranged on the workbench, two rows of water inlets 4 are respectively arranged on two side plates of the water tank 3 at equal intervals, the positions of the two rows of water inlets 4 are arranged in a staggered manner, each water inlet 4 is connected with a water pump in a water storage tank through a water pipe, a water nozzle 5 is further screwed on each water inlet 4, and a multilayer filter screen is arranged in each water nozzle 5, so that impurities are blocked, and splashing caused by over-rush of water outlet of the water inlet 4 is prevented;

two limiting strips 6 are fixed in the middle of the water tank 3 through screws, the two limiting strips 6 are arranged in parallel with the side plate provided with the water inlet 4, the lower die 2 is arranged between the two limiting strips 6, a plurality of rows of fixing holes are formed in the water tank 3, and when the lower dies 2 with different specifications are selected, the two limiting strips 6 can be fixed in corresponding positions;

a water outlet 7 is also arranged in each of the water tanks 3 on the two sides of the lower die 2, and the water outlets 7 are connected with the water storage tank through water pipes so as to enable water to circulate between the water tanks 3 and the water storage tank;
