A core slider for die-casting an oil pump casing

Abstract

The invention discloses a core sliding block for die casting of an oil pump housing. The core sliding block comprises a fixing base, a first tapered cylinder and a second tapered cylinder, wherein the first tapered cylinder and the second tapered cylinder are perpendicularly arranged on the front side of the fixing base, and intersect with each other; an arc housing is arranged on the front side of the fixing base, and is connected with the outer walls of the first tapered cylinder and the second tapered cylinder; and a weight-reducing punch technological hole is formed in the fixing base. According to the invention, the core sliding block can be fitted with a fixed mold of a die casting mold, so as to improve the precision of a die casting blank, reduce allowance and machining workload, and lower material cost and machining cost; and moreover, the weight-reducing punch technological hole can be fitted with a weight-reducing punch of the die casting mold, so that a weight-reducing hole is additionally formed in the oil pump housing to reduce the weight of the oil pump housing and improve the heat dispersion performance of the oil pump housing.

Description

technical field [0001] The invention relates to the field of die-casting molds for aluminum alloy oil pump casings, in particular to a core slider for die-casting oil pump casings. Background technique [0002] Some parts in automobiles are produced with aluminum alloy materials, and aluminum alloy die-casting molds greatly improve the processing efficiency of aluminum alloy parts and reduce finishing steps, thereby enhancing structural strength and reducing production costs. [0003] The oil pump casings of automobile engines are mostly made of aluminum alloy materials, and the structure is complex. The requirements for aluminum alloy die-casting molds are relatively high. The core body design of ordinary die-casting molds is simple, and the blank margin is large, which increases the workload and cost of machining. The cost of production needs to be improved. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a c...
