[0026] For a mold for medical syringe accessories provided by the present invention, through the setting of the cooling assembly 7 and the cooling groove 14, it can absorb the heat after injection molding of the syringe accessories, thereby accelerating the cooling speed of the syringe accessories, shortening the molding time of the syringe accessories, improving the injection molding production efficiency of the syringe accessories, and the setting of the floating block 76 and the floating rod 77 is used to facilitate the observation of the height of the cooling liquid inside the cooling box 71, and the cooling liquid can be supplemented in time, so that the heat conduction effect on the syringe accessories is good, and the setting of the heat dissipation assembly 8 can also control the temperature of the cooling liquid inside the cooling box 71, so that it is always in a low-temperature state during the circulating flow, ensuring the rapid cooling of the syringe accessories after injection molding; through the setting of the electromagnet 5 and the ejection assembly 6, it can exert a force on the syringe accessories after injection molding to push them out, thereby avoiding the situation of adhesion between the syringe accessories and the mold body 1, improving the collection efficiency of the syringe accessories by the staff, and accelerating the injection molding production efficiency of the syringe accessories.

[0027] In the embodiment of the present invention, during use, the electric telescopic column 13 is powered on and starts, moving the support plate 21 downward so that the support plate 21 fits with the mold body 1.
