Description

Technical Field

[0001] The utility model relates to the technical field of graphite moulds, and more specifically to a graphite mould which is easy to assemble and disassemble. Background Art

[0002] Graphite mold is an industrial mold used to manufacture metal parts or products with complex shapes. It is made of graphite material, which is a material with high crystallinity and high temperature resistance, so it is very suitable for making molds.

[0003] The Chinese patent authorization announcement number: CN219900216U provides a spliced ​​graphite mold that is easy to disassemble and assemble. This patent is provided with an L-shaped fixing plate, a gripping rod, a heat-insulating rubber sleeve, an inner groove and an outer convex strip. When in use, the left fixed mold, the middle mold, and the right fixed mold are spliced ​​together, and the liquefied metal is poured into the filling hole. After it cools, a rod-shaped workpiece can be obtained. When assembling the middle mold, the operator holds the gripping rod and lifts it upward, moves the middle mold to the corresponding position and slowly lowers it, so that the outer convex strip slowly slides down along the inner groove, and the inner groove and the outer convex strip are engaged with each other, so that the left fixed mold, the middle mold, and the right fixed mold are accurately connected. When disassembly is required, just grab the gripping rod and pull it upward. The L-shaped fixing plate provides physical support for the gripping rod, and the heat-insulating rubber sleeve can insulate and prevent scalding, realizing the function of easy disassembly and assembly.

[0004] However, in the above patent, when the workpiece is cooled and formed for demolding, not only is the cooling time long, but the workpiece is easily damaged during the demolding process. At the same time, when the left fixed mold, the middle mold, and the right fixed mold are assembled, unevenness is likely to occur, resulting in irregular molded workpieces. Utility Model Content
