[0037] Refer to the attached Figure 1-4 The utility model provides an injection mold that is easy to cool, including the following structure:

[0040] In this embodiment, Figure 1 As shown, a fixed mold 11 is fixedly provided at the bottom of the truss 1 , and a movable mold 12 is movably connected to the front side of the fixed mold 11 .

[0041] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the front end of the deflection frame 22 is fixedly connected to the top of the lifting electric push rod 3, and a connecting pipe 23 is fixedly provided at the front end of the deflection frame 22, and the bottom of the connecting pipe 23 is sleeved with the top of the telescopic tube 61.

[0042] The deflection electric push rod 21 changes the working position of the deflection frame 22 on the bracket 2, and the deflection frame 22 drives the lifting electric push rod 3 to deflect, thereby changing the working positions of the frame 31 and the fixed frame 71 at the bottom of the lifting electric push rod 3. When the working position of the fixed frame 71 changes, the vacuum suction cup 9 cooperates to move the injection molded parts on the movable mold 12 to the outside of the equipment.
