[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-2 As shown, the utility model provides a bottom plate 1 and a top plate 2 supported and fixed thereon. The distance between the bottom plate 1 and the top plate 2 is the space for mold injection and cleaning operations. An injection mold body 3 for injection molding is assembled on the bottom plate 1. A water inlet and a water outlet for introducing water flow are provided on the mold bottom 301 of the injection mold body 3. The water flow repeatedly flows in the mold bottom 301 to absorb internal heat and then is discharged for cooling. An air blowing rack 6 for cleaning is assembled on the top plate 2, and the bottom plate 1 and the top plate 2 are supported and fixed by four support rods 8 supported at the four corners.

[0020] The surface of the base plate 1 is connected to an injection mold body 3, and the injection mold body 3 is composed of a mold bottom 301 and two mold surfaces 302. The mold bottom 301 is connected to the base plate 1 and forms a detachable structure, which is convenient for users to replace different molds. The bottom of the mold bottom 301 is fixedly connected to the base plate 1 by an angle code 9 and an inserted and locked screw 10. The two mold surfaces 302 are symmetrically and tightly connected to the upper end surface of the mold bottom 301. The mold surfaces 302 on both sides are opened outward and a latch 4 connected to the mold bottom 301 is provided on one side of the bottom. The two mold surfaces 302 are combined with the mold bottom 301 below to form an internal injection space, and a liquid injection port is provided on one of the mold surfaces 302. After injection molding, the mold surfaces 302 on both sides are respectively opened outward and connected and opened by the latch 4 at the bottom. After the mold surfaces 302 on both sides are opened, the inner side of the mold surface 302 and the inside of the mold bottom 301 are exposed, which is convenient for later cleaning operations.

[0021] The lower end surface of the top plate 2 is connected to a telescopic shaft 5, and the upper end surface of the top plate 5 is provided with a telescopic cylinder 11 for driving and controlling the telescopic shaft 5 to extend and retract. The end of the telescopic shaft 5 is connected to a blowing rack 6, and the blowing rack 6 moves synchronously under the extension and retraction of the telescopic shaft 5. The bottom of the blowing rack 6 is equipped with at least two blowing nozzles 7 for blowing toward the injection mold body 3. The blowing nozzles 7 are distributed at the bottom of the blowing rack 6 in a matrix manner, and an air inlet 12 for internally connecting all the blowing nozzles 7 is provided on one side of the blowing rack 6, and the blowing rhythm and the switching state are driven by the blowing cylinder 13 on the top.

[0022] Compared with traditional technology, the present technical solution adopts a structure combining injection molding and blowing. After the injection mold body 3 used for injection molding is opened to take out the injection molded part, the blowing nozzle 7 mounted on the blowing frame 6 above is moved to the top of the injection mold body 3 under the control of the telescopic shaft 5, and the inside of the injection mold body 3 is blown to clean the internal residues without manual cleaning, thereby improving the overall production efficiency.
