Description

Technical Field

[0001] This utility model relates to a 3D printed integral mold core with a heat insulation structure. Background Technology

[0002] Patent document CN221540376U discloses a mold core assembly, which includes a base frame, a base plate welded to the top of the base frame, a lower mold shell welded to the center of the top of the base plate, an insert post penetrating through the inner wall of the bottom center of the lower mold shell and the center of the inner wall of the base plate, a nut threaded to the bottom end of the outer wall of the insert post, and a mold ring threaded to the top of the inner wall of the lower mold core shell. Coolant can be introduced into the mold core through a liquid-passing pipe, while excess gas inside the mold core is discharged through another set of liquid-passing pipes. The coolant introduced into the mold core flows steadily and quickly through the pipes and the outlet ring to the bottom of the inner wall of the mold core, whereupon the coolant level slowly rises. Once all the gas inside the mold core is discharged, the coolant is discharged through another set of liquid-passing pipes. This rapid replacement of coolant quickly dissipates heat transferred to the surface of the mold core, resulting in a good cooling effect. However, this type of mold core cannot form a cooling section internally, leading to a low cooling rate in the extruded product and poor surface finish and dimensional accuracy. Therefore, it is necessary to optimize its structure to overcome these defects. Utility Model Content

[0029] The advantages of this utility model are:

[0030] This mold core is manufactured using 3D printing, with all parts integrally molded. This not only simplifies the manufacturing process but also improves the overall integrity and structural strength of the mold core. The spiral cooling channels correspond to the front section of the raw material guiding component, allowing for more effective cooling of the raw material. This helps to accelerate the cooling process and improve production efficiency. The venting side holes help to expel gas in a timely manner during injection molding, preventing the formation of bubbles and defects, thereby improving the appearance quality and performance of the product. The isolation layer separates the load-bearing assembly components into a cooling front section and a heat-insulating rear section, reducing heat transfer and loss. This not only improves cooling efficiency but also helps to maintain the overall temperature stability of the mold core, further ensuring product quality. Attached Figure Description
