Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0028] See also Figure 1-5 The utility model provides a technical solution: a door and window injection mold with cooling function. It includes a bottom plate 110, on which a lower mold 120 and an upper mold 170 are installed, on which a cooling component for cooling the lower mold 120 is installed, and on which a recovery component for exchanging heat for the cooling component is installed;

[0029] The cooling assembly includes a cooling plate 210, a cooling groove 121 is provided on the side wall of the lower mold 120, the cooling plate 210 is slidably connected in the cooling groove 121, a cooling pipe 220 is installed on the cooling plate 210, both ends of the cooling pipe 220 are installed on the inner wall of one end of the cooling plate 210, a first connecting pipe 230, a second connecting pipe 240 and a handle 250 are installed on the outer wall of one end of the cooling plate 210, the handle 250 is located between the first connecting pipe 230 and the second connecting pipe 240, one end of the first connecting pipe 230 and the second connecting pipe 240 both penetrate into the cooling plate 210, and one end of the first connecting pipe 230 and the second connecting pipe 240 are respectively installed at both ends of the cooling pipe 220. Through the contact between the cooling pipe 220 and the lower mold 120, the cooling pipe 220 cools the lower mold 120, thereby accelerating the cooling efficiency of the lower mold 120. The handle 250 facilitates the removal of the cooling plate 210, and the maintenance, cleaning and replacement of the cooling tube 220 on the cooling plate 210, so that the cooling tube 220 is not easily blocked or damaged, and the cooling tube 220 can be used normally. Both ends of the cooling tube 220 and the first connecting tube 230 and the second connecting tube 240 are detachable, so that the cooling tube 220 can be maintained, replaced and cleaned.

[0030] The cooling assembly further includes a temperature controller 260, which is mounted on the bottom plate 110 and located on one side of the lower mold 120.
