Abstract
The utility model relates to the one-time formed mould structure of a kind of main bearing end cover bolt head external tooth, comprise mould bases (1), die cavity (2) and mould (5), the side of described mould bases (1) is furnished with mould (5), die cavity (2) is furnished with in described mould (5), the madial wall of described die cavity (2) is around being furnished with some shaped projections (4), the side-walls of its openend is furnished with the step (3) being close to this sidewall, and an end face of described step (3) is connected with shaped projection (4).The utility model structure is simple, by increasing ledge structure in die cavity, be conducive to playing guide effect to material in cold-heading molding process, be squeezed in process at material, material can be made to flow regularly, efficiently avoid the trickle changing of the relative positions between the punch die of mould in the extruded process of material and bed die and the generation of situation that misplaces of the product nose shape caused.
Description
Technical field
The utility model relates to mould applications, particularly relates to the one-time formed mould structure of a kind of main bearing end cover bolt head external tooth.
Background technology
The main bearing end cover bolt of automobile is generally die cast, but the mould of normal conventional 12 toothing easily produces dislocation in cold-heading process, causes Product Assembly difficulty or assembling to be skidded, is unfavorable for the carrying out of large-scale production.
Summary of the invention
Technical problem to be solved in the utility model is to provide the one-time formed mould structure of a kind of main bearing end cover bolt head external tooth, structure is simple, by increasing ledge structure in die cavity, be conducive to playing guide effect to material in cold-heading molding process, be squeezed in process at material, material can be made to flow regularly, efficiently avoid the trickle changing of the relative positions between the punch die of mould in the extruded process of material and bed die and the generation of situation that misplaces of the product nose shape caused.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of main bearing end cover bolt head external tooth one-time formed mould structure, comprise mould bases, die cavity and mould, the side of described mould bases is furnished with mould, die cavity is furnished with in described mould, the madial wall of described die cavity is around being furnished with some shaped projections, the side-walls of its openend is furnished with the step being close to this sidewall, and an end face of described step is connected with shaped projection.
One as mould structure described in the utility model is supplemented, and the plane at described shaped projection and step place is orthogonal, the matching form of this shaped projection and bolt head external tooth.
beneficial effect
