Insulation can mold

A heat preservation box die comprises a female die and a male die, the female die is gradually expanded from bottom to top to form an inclined wall inclining outwards, and the male die and the femaledie are matched with each other to form a heat preservation box-shaped cavity. A sprue gate for injection molding is formed in the center of the bottom of the female die; a first hollow layer is further arranged in the male die, the first hollow layer is close to the outwards-protruding face of the male die, a first water inlet and a first water outlet are further formed in the end cover face of the male die, and the first water inlet and the first water outlet are communicated with the first hollow layer; the hollow layers are arranged in the male die and the female die, water is added for backflow cooling, the cooling time of the heat preservation box in the forming process can be shortened, and therefore the production speed is increased. 一种保温箱模具，包括凹模和凸模，所述凹模从底部到顶部逐渐扩大，形成向外倾斜的斜壁，所述凸模与凹模相互配合，形成保温箱状的腔体；所述凹模的底部中心处
