Description

Take 3d metal printing bottle base injection mold of spiral water route Technical Field The utility model relates to the technical field of injection molds, in particular to a 3d metal printing bottle blank injection mold with a spiral waterway. Background In the injection molding process of bottle blanks, thermal residual stress is easy to generate in the following 2 stages, namely, a cooling stage of bottle blank products in a cavity and a cooling stage of bottle blank products from a demolding temperature to a room temperature. Therefore, in order to achieve high-efficiency production and to obtain an injection molded article excellent in performance, the mold must be temperature-regulated. The mold temperature directly affects the quality and production efficiency of the injection molded article, and is controlled and regulated appropriately mainly by the cooling system of the mold. The traditional cooling water channel can only be processed into a simple straight hole, and when the injection molding part is complex in shape, the cooling effect is poor, and the deformation of the part is large. Disclosure of utility model Aiming at the problems, the utility model aims to provide the 3d metal printing bottle blank injection mold with the spiral waterway, which has novel and reliable structure and good cooling effect. The technical scheme of the utility model relates to a 3d metal printing bottle blank injection mold with a spiral waterway, which is characterized by comprising a mold core formed by printing 3d metal, wherein a bottle blank product cavity is arranged in the mold core, a spiral cooling waterway is arranged in the mold core, the spiral cooling waterway is circumferentially arranged along the outer side of the bottle blank product cavity, a water inlet and a water outlet of the spiral cooling waterway are arranged in left and right side areas of the upper area of the mold core, and the cross section of the spiral cooling waterway is in a water drop shape. Preferably, the bottle base product die cavity is arranged along the height direction of the die core, the upper part of the bottle base product die cavity is hemispherical, the middle part of the bottle base product die cavity is cylindrical, the lower part of the bottle base product die cavity is in a round table shape with a small upper part and a large lower part, the top of the spiral cooling water channel is positioned at the outer side of the top end of the upper part of the bottle base product die cavity, and the bottom of the spiral cooling water channel is positioned at the outer side of the bottom end of the lower part of the bottle base product die cavity. The utility model adopts a 3d metal printing mode to arrange the cooling water channel with the spiral inside, has novel and reliable structure and good cooling effect. Drawings FIG. 1 is a schematic diagram of the structure of the present utility model; FIG. 2 is a schematic view of the structure of FIG. 1 from another perspective; FIG. 3 is a front view of the present utility model; FIG. 4 is a cross-sectional view taken along line A-A of FIG. 3; FIG. 5 is a schematic view of a spiral cooling water channel according to the present utility model; Wherein, the mold core is 1-the mold core is 2-the bottle blank product cavity is 3-the spiral cooling water channel is 31-the water inlet is 32-the water outlet. Detailed Description The present utility model will be described in further detail with reference to the accompanying drawings. As shown in fig. 1 to 5, the utility model provides a 3d metal printing bottle blank injection mold with a spiral waterway, which comprises a mold core 1 formed by printing 3d metal, wherein a bottle blank product cavity 2 is arranged in the mold core 1, a spiral cooling waterway 3 is arranged in the mold core 1, the spiral cooling waterway 3 is circumferentially arranged along the outer side of the bottle blank product cavity 2, a water inlet 31 and a water outlet 32 of the spiral cooling waterway 3 are arranged in left and right side areas of the upper area of the mold core 1, and the cross section of the spiral cooling waterway 3 is in a water drop shape.
