The fixing screw 12 can adjust the spacing of the nozzle 7 according to the style of the injection molding shell of the shield, so that the nozzle 7 can evenly spray the paint on the surface of the injection molding shell. Example 2

[0037] Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 , also includes a cylinder 13, a control rod 14 and a lever 16. The cylinder 13 is vertically connected to the base plate 1 through a bracket. The output shaft of the cylinder 13 is fixed with the control rod 14 by bolts. The upper end of the control rod 14 is connected to the baffle 4. The middle part of the control rod 14 is connected to the lever 16. A reserved groove 15 is opened on the mold 3. The lever 16 can pass through the reserved groove 15, and the lever 16 can frictionally contact with the mold cover 301.

[0038] After spraying is completed, the cylinder 13 is turned on, and the cylinder 13 drives the control rod 14 to slide upward. The control rod 14 lifts the baffle 4 upward, and the lever 16 contacts and pushes the mold cover 301 to open. The staff can easily take out the shield injection molded shell in the mold 3, which reduces the complicated operations in the traditional process and improves the efficiency of the shield injection molded shell spraying process.

[0039] Please refer to Figure 1 , Figure 2 , Fig. 9 and Fig.10 , also includes a guide bracket 17, a protective shell 18, a first return spring 19 and a sieve plate 20.

[0040] Please refer to Figure 1 , Figure 2 , Fig.11 and Fig.12 , also includes a wedge block 21, a fixed pulley 22 and a pull rope 23. The wedge block 21 is fixedly connected to the middle part of the control rod 14. The wedge block 21 can be in friction contact with the protective shell 18.

[0041] A downward inclined surface is arranged on the left side of the wedge block 21, and the inclined surface can contact the lower part of the left protective shell 18. Therefore, when the opening cylinder 13 drives the control rod 14 to slide upward, the wedge block 21 moves synchronously with the control rod 14 and pushes the left protective shell 18 to slide to the left, and the left protective shell 18 will pull the pull rope 23, and the pull rope 23 will pull the right protective shell 18 to move to the right. Therefore, when the opening cylinder 13 opens the mold cover 301, the protective shell 18 can be opened at the same time.

[0042] Please refer to Fig.13 , and also includes a fan 24. Four of the fans 24 are evenly arranged on the bottom surface of the protective shell 18.

[0045] The working principle of the embodiment of the present invention is as follows: The cylinder 13 is turned on to push the control rod 14 to move upward to open the protective shell 18, and then the mold 3 is slid to the top of the mounting frame 2 and is fixed by the clamping block 25, and the shielding device injection molding shell is placed in the mold 3, and the control cylinder 13 drives the control rod 14 to move downward to close the protective shell 18 and the mold cover 301, and the power assembly 11 is turned on to drive the screw rod 10 to rotate, and the screw rod 10 will drive the push rod 8 to reciprocate, and the push rod 8 will push the nozzle 7 to move to the left to the top of the mold 3, and the nozzle 7 will inject the shielding device injection molding shell. The push rod 8 drives the nozzle 7 to move back and forth to complete the spraying. At this time, the power assembly 11 is turned off and the cylinder 13 is turned on. The cylinder 13 will drive the control rod 14 to move upward, and the dial block will lift the mold cover 301. The wedge block 21 will push the protective shell 18 to open. At this time, the staff can take out the shielding device injection molded shell and put in another shielding device injection molded shell again. Repeat the above actions to realize automatic and convenient spraying process. When the mold 3 needs to be replaced, the connecting rod 27 can be pulled downward, and then the mold 3 can be taken out and replaced.
