A die-casting mold with multiple inserts and compact structure

Abstract

The invention relates to a die-casting mold with multiple inserts and a compact structure, which includes an upper template and a lower template, an upper mold core and a lower mold core are arranged between the upper template and the lower template, and several forming sliders are arranged around the lower template. The mold cavity between the upper mold core and the lower mold core is divided into a left cavity and a right cavity, and the middle part of the left cavity is provided with a shaft hole core embedded in the lower mold core, and the position between the left cavity and the right cavity is provided with the upper mold core. Connected boss molding inserts, one side of the boss molding inserts is embedded with auxiliary molding inserts connected with the upper template, and the inside of the auxiliary molding inserts is arranged side by side with cylindrical molding tubular inner inserts, which are located on the right side A forming mandrel is embedded in the lower mold core below the forming tubular inner insert, and the upper end of the forming mandrel is offset against the lower end of the forming tubular inner insert. The present invention has many inserts and reasonable arrangement, solves the problem that the bosses and through holes in the middle are not easy to be formed, and meets the strict forming requirements of the transmission case.

Description

technical field [0001] The invention relates to the field of die-casting molds for gearbox casings, in particular to a die-casting mold with multiple inserts and compact structure. Background technique [0002] The gearbox housing is a relatively complex component in the automobile assembly, such as figure 1 As shown in the figure, the structure of this gearbox casing is relatively complicated, and a boss is arranged in the middle, and the boss is provided with a through hole with a relatively high precision requirement and a relatively thick wall. According to the conventional design, the core is directly used. The shaft is formed, but the mandrels with two holes side by side are not easy to arrange, the structure setting is difficult to be reasonable, and the heat dissipation and precision are difficult to control, so a new insert design is required. [0003] In addition, many positions of the gearbox casing are provided with oblique holes, and the corresponding drive str...
