Abstract

The invention relates to a gearbox casing die-casting die which comprises a movable die (2), a fixed die frame (4), a movable die frame (3), a fixed die (6), a sprue bush (8), an inclined guide pillar (9), a fixed die core I (10), a fixed die core II (11), a fixed die core III (12), a guide pillar (13), a guide sleeve (8), a first sliding block (20) and a second sliding block (24). The three fixed die cores are fixed with the fixed die (6) together. The gearbox casing die-casting die is characterized in that the first sliding block (20), the second sliding block (24), the fixed die (6), the movable die (2), the fixed die core I (10), the fixed die core II (11), the fixed die core III (12) and a movable die insert (19) form a gearbox casing die cavity (1). According to the invention, a produced gearbox casing casting is high in quality and has no appearance defect; the production efficiency is high; the defects of shrinkage porosity, air pores, size deviation and the like are overcome; the gearbox casing casting which completely meets the requirements can be produced; the casting is high in quality.

Description

technical field [0001] The invention relates to a metal die-casting mold, in particular to a gear case die-casting mold. Background technique [0002] Gear box parts are larger in size, and are composed of figure 1 It is known that the structural shape is complex, the technical requirements are high, and the production is very difficult. The existing gear box die-casting molds have problems such as unsmooth metal liquid punching, insufficient pressure transmission, and prone to defects such as shrinkage, porosity, and dimensional deviation. Therefore, casting The quality is not high. Contents of the invention [0003] In view of the above deficiencies, the purpose of the present invention is to provide a gear box die-casting mold with high product casting quality. The produced gear box has good surface quality, no defects in appearance, high production efficiency, and fully meets the design requirements. [0004] The technical solution of the present invention is realize...
