The specific embodiment

Accompanying drawing only is an embodiment of the present utility model.

Below in conjunction with accompanying drawing summary of the invention of the present utility model is described further:

With reference to Fig. 1, Fig. 2, shown in Figure 3, pneumatic dustproof backflow cuts sand blasting sand device, comprise a spray gun 2, one is sprayed alphabetical mould stationary housing 14, a storage sand container 5, a sand suction pipe 6, spray gun 2 is by jackscrew 4, the dust cover bonnet 3 that dams places and is connected dust cover 1 inner chamber that dams, be connected with pressure regulator valve 7 on the spray gun handle, sand suction pipe 6 one ends are connected with spray gun 2, the other end is placed in the storage sand container 5, storage sand container 5 is connected with the dust cover 1 vertical port that dams, dust cover 1 inner chamber that dams is provided with fixed head 8, concentric fixing hole 9 is established at its fixed head 8 middle parts, fixed head 8 bottoms are provided with back sand hole 10, the front port of dust cover 1 of damming is a sandblast nozzle 11, sandblast nozzle 11 inboards are provided with chamfering 12, returning sand hole 10 communicates with storage sand container 5, dust cover 1 outer wall that dams is provided with fixedly port lid 13, the alphabetical mould stationary housing 14 of said injection, bottom one side of its alphabetical mould stationary housing 14 is provided with oblong openings 16, opening 16 both sides all have sliding tray 17, at least insert required heavy hole type-word mother tuber 18 in its sliding tray 17, said heavy hole type-word mother tuber 18 upper punches are pressed with hollow literal and numeral, the sealing of oblong openings 16 1 ends, the other end is open, its open end will sink hole type-word mother tuber 18 ordering according to the rules and insert successively, insert L type baffle plate 19 at last, L type baffle plate 19 connects as one by set bolt 20 and alphabetical mould stationary housing 14, and pressure regulator valve 7 is connected with the heat pump sebific duct.
