Abstract
The utility model relates to a flow channel structure of a die-pressing die of an automobile pump cover. The flow channel structure of the die-casting die of the automobile pump cover comprises a lower die (1) and die cavities (5), wherein the two die cavities (5) are symmetrically arranged on the two sides of the upper end face of the lower die (1), a main flow channel (4) is arranged on one side of the middle of the upper end face of the lower die (1), two branch flow channels (3) connected with the main flow channel (4) are arranged between the die cavities (5), and one sides of the branch flow channels (3) are connected with a plurality of side flow channels (2) which are connected with the cavity (5) on the corresponding side. The flow channel structure of the die-casting die of the automobile pump cover is simple in structure, high in high temperature resistance and good in lubricating performance, and service life is prolonged.
Description
Technical field
The utility model relates to the auto parts and components field, particularly relates to a kind of flow passage structure of die casting of automobile pump cover.
Background technology
The pump cover of automobile is important components very in the automobile engine, its complex structure, the requirement of strength height, the required precision height, in the production process of pump cover, generally be that two pump covers are produced in a secondary mould die casting simultaneously, it all is that sprue is arranged between two die cavitys that existing mould flows to design, and link to each other with die cavity by side runner, and very short side runner design often, make the distance between sprue and the die cavity too near, defective work appears in size inaccuracy or the insufficient strength of product when causing die cast.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of flow passage structure of die casting of automobile pump cover, and is simple in structure, increased runner, lengthened the length of side runner, and the pressure of sprue reduces when making die casting, guaranteed the quality of product.
The technical scheme that its technical problem that solves the utility model adopts is: the flow passage structure that a kind of die casting of automobile pump cover is provided, comprise counterdie and die cavity, bilateral symmetry is furnished with two die cavitys on the upper surface of described counterdie, centre one side of the upper surface of described counterdie is furnished with sprue, be furnished with two runners that link to each other with sprue between the described die cavity, a side of described runner is connected with some side runners and links to each other with the die cavity of a corresponding side.
The side runner that connects on the described runner has two at least.
The length of described side runner is at least 30mm.
Beneficial effect
The utility model relates to a kind of flow passage structure of die casting of automobile pump cover, and is simple in structure, increased runner, lengthened the length of side runner, the pressure of sprue reduces when making die casting, and the die cavity on both sides and the distance between the runner are increased, and has guaranteed the quality of product.
