In the thermal spraying process, no special requirements are required on the material of the base material, the thickness of the coating is controllable, the size of the workpiece is not limited, the spraying equipment is simple, the spraying deposition rate is high, the material consumption is low, the economic benefit is obvious, the particles of the cobalt alloy nano ceramic composite material are better in melting due to large specific surface area and high activity, the particles are violently deformed after contacting the inner wall of the charging barrel body 200 in thermal spraying, the tiling property is good, and the performance of the cobalt alloy nano ceramic can be exerted. The hot isostatic pressing technology is that the product is placed in a closed container, inert gas is filled into the container, and the product is sintered or densified at a very high temperature and a very high pressure, so that the processed material still keeps a fine-grained crystal structure, a good consolidation effect of metal and ceramic is realized, and the wear resistance and the corrosion resistance of the cobalt alloy nano-ceramic composite material are better achieved.
As an alternative embodiment, the ceramic material of the inner wall of the cartridge body 200 is fixed to the inner wall of the cartridge body 200 by vacuum diffusion welding.

Meanwhile, the pressure applied during welding is small, the overall plastic deformation of each section is small, the precision is high, and the concentricity of the charging barrel body 200 after sectional processing can be ensured.
As an alternative embodiment, as shown in fig. 1, the heat exchange device 100 is a water-type cold and hot integrated mold temperature controller, the power is 6KW to 120KW, the temperature of the circulating water can be heated to 120 ℃ to 180 ℃, and the external heat can also be absorbed by the water circulation at normal temperature, such as 20 ℃, the water-type cold and hot integrated mold temperature controller has a relatively low heating temperature and a relatively slow heating process, but has a good heat conduction effect, is economical in cost, and is clean to use.

The two heat exchange devices 100 arranged outside can be conveniently selected according to different die-casting materials and operating environments in actual operation, and the applicability of the charging barrel of the die-casting machine is improved.
As an alternative embodiment, the material of the cartridge body 200 is heat-resistant steel, and is processed by QPQ process after being manufactured in stages and finished. The heat-resistant steel has higher strength and good chemical stability at high temperature. The QPQ is an abbreviation of English Quench-Polish-Quench, namely a quenching-polishing-quenching process, improves the wear resistance, corrosion resistance and fatigue resistance of the charging barrel body, only generates extremely small deformation, and finally improves the service life of the charging barrel of the die casting machine.
As an alternative embodiment, as shown in fig. 1, a feed inlet 201 is provided on the cartridge body 200, the external molten metal enters the cartridge body 200 of the die casting machine through the feed inlet 201, and the feed inlet 201 of the cartridge body 200 is nitrided, in fact, the front portion of the cartridge body 200, i.e., the first section 202, the second section 203 and the third section 204 is nitrided.
