[0002] Molds are various tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. Among them, the precision casting mold refers to the general term for the process of obtaining castings with precise dimensions. Compared with the traditional sand casting process, the castings obtained by precision casting are more precise in size. Precision casting is also called lost wax casting. Its products are precise, complex, and close to the final shape of the parts, so they can be used directly without or with little processing. Since the casting requirements of pipe fittings are relatively high, a precision casting pipe fitting mold is required when casting them.

[0009] In order to facilitate filtering of impurities in the coolant, as a preferred embodiment of the precision casting pipe fitting mold of the utility model, a filter screen is installed inside the water outlet pipe.

[0010] In order to facilitate positioning of the upper mold, as a preferred precision casting pipeline component mold of the utility model, the upper end surface of the lower mold is provided with a positioning groove, and the lower end surface of the upper mold is fixedly connected with a positioning block matching the positioning groove.

[0011] In order to facilitate the fixation of the lower mold and the cooler, as a preferred precision casting pipe fitting mold of the utility model, a bottom plate is installed at the lower end of the lower mold, and an L-shaped connecting plate fixedly connected to the lower side of the cooler is fixedly connected to the left side of the bottom plate.
