in the above technical solution, a plurality of second glass observation windows 81 are circumferentially arranged on the casting pot 8;

the working principle is as follows:

(1) in the design, under the pushing action of the pressing disc 1 in the mixing pot 7 and the vacuum state of the inner cavity of the pouring pot 8, as the combustion chamber 9 is completely in the inner cavity of the pouring pot 8 in the vacuum state, the slurry flows into the combustion chamber 9 from the short arc tube 45 in a totally closed flow field, the slurry flows towards the middle and the gas is discharged upwards from the side in the inner cavity 92 of the combustion chamber 9, and the slurry channels (i.e. the circular tube 521) and the residual gas exhaust channel (i.e. the circle of big holes 512 and the circle of small holes 522) are provided with a separation wall, so that the exhaust can be realized, when the gas in the inner cavity of the combustion chamber 9 is completely discharged and the slurry is completely filled, the slurry can be guided into the annular space between the outer side of the circular tube 521 and the side edge of the positioning disc 51 from the circle of big holes 512;

the key point here is that according to the principle of conversion between kinetic energy and static energy, the mechanical energy of the fluid is conserved, (i.e. kinetic energy + gravitational potential energy + pressure potential energy are constant), when the slurry flows through the circle of large holes 512, the slurry will be quickly filled into the "annular space" due to the large hole diameter, the large flow rate and the small pressure, in other words, the slurry can easily enter the "annular space" from below through the circle of large holes 512; however, the top pressure plate 52 is provided with a ring of small holes 522, and the smaller the diameter of the holes, the smaller the cross section of the holes increases the kinetic energy, resulting in lower static pressure energy, and thus a pressure difference is generated between the two sides of the pressure plate 52, in other words, when the slurry is to be discharged upwards from the "annular space" through the ring of small holes 522, it becomes very difficult to form a stable damping effect,

its main advantage lies in: the circle of big holes 512 on the positioning plate 51 is matched with the circle of small holes 522 on the upper pressure plate 52, so that a structure of a differential pressure damping valve can be formed at the feed inlet part of the combustion chamber 9, the combustion chamber 9 filled with the slurry can automatically wait for other combustion chambers 9 which are not filled with the slurry (caused by the stress difference of the slurry), all the combustion chambers 9 can be uniformly and stably filled with the slurry at the same time, and the formation of the explosive column of the multi-engine operated injection pouring by remote operation is realized.

(2) In this design, it is further advantageous to ensure that the positioning plate 51 can be stably fixed on the upper port 91 of the combustion chamber 9, so as to improve the support and stability, and facilitate the assembly and disassembly, thereby improving the assembly efficiency.

(3) In this kind of design, its further advantage is, guarantees that pressure disc 52 can stably install in positioning disk 51 upper end for both carry out inseparable laminating, and convenient loading and unloading improve assembly efficiency simultaneously.

(4) In this design, it is further advantageous to ensure the sealing performance after the feeding stub 524 is butted with the short arc pipe 45, and at the same time, the loading and unloading are convenient, and the assembly efficiency is improved.

(5) In this design, it is further advantageous that the slurry pressed out from the ring of small holes 522 can be limited by the containing ring 522, so as to provide a containing effect for the observation of the personnel.

(6) In this design, by providing a leakage plate 6 sandwiched between the positioning plate 51 and the upper port 91 of the combustion chamber 9, it is further advantageous that the slurry (high viscosity non-newtonian fluid) entering from the inlet stub 524 will adhere directly to the cone 632 at the upper end of the core 63, then slowly spread downward on the tapered surface of the cone 632, and finally be introduced into the inner cavity 92 of the combustion chamber 9 from the inner periphery of the leakage orifice 61, in such a way that the slurry is poured more uniformly and can be stably filled into the inner cavity 92 of the combustion chamber 9;

the second further advantage is that: the positions of the three thick arc-shaped fine holes are in right-opposite matching with the circle of large holes 512 to realize communication, so that discharged gas and subsequent slurry filled in the inner cavity 92 of the combustion chamber 9 can upwards penetrate into the circle of large holes 512 from the three thin arc-shaped leakage holes;

(7) in the design, the leakage disc 6 is further advantageous in that stable clamping of the leakage disc 6 can be ensured, meanwhile, the device is convenient, and the assembly efficiency is improved;

(8) in this design, it is further advantageous that the detachment of the core mold 63 can be facilitated, and at the same time, the engagement of the core mold 63 with the drain pan 6 can be ensured to be more stable, which improves the applicability of the device.

(9) In this design, it is further advantageous that the operator can observe the upper end of each pressure plate 52 through a plurality of glass windows 81 outside the casting pot 8, i.e. by observing the ring of small holes 522 of the pressure plate 52 for slurry overflow, to determine whether the combustion chamber 9 is full of slurry.
