Abstract
The utility model discloses a cold extrusion mould for a ball pin. The cold extrusion mould is characterized in that a formwork is internally provided with an upper mould outer ring and a lower mould outer ring respectively; a lower mould middle ring is sheathed in the lower mould outer ring and is internally provided with a first mold core and a second mold core respectively; the upper end of an ejector rod is sheathed in the second mold core; an upper mold core is arranged in the upper mould outer ring; and an insert is embedded in the upper mold core. According to the cold extrusion mould, the mold cores are installed in a split way, so that the material utilization rate is improved, and the mold cores only need to be replaced when being worn or broken; and therefore, the mould utilization rate is improved, the wastes caused by abrasion or breakage of the mold cores can be reduced, the production efficiency is improved, and the product quality is guaranteed.
Description
Technical field
The utility model relates to a kind of auto parts and components processing mold, is a kind of ball pin cold extrusion die specifically.
Background technology
At present, domestic most producers ball pin blank forges general employing thermal forging technology.The defect such as large by the ball pin allowance of this kind of explained hereafter, the production cycle is long, and frock service life is short, just easy generation mismatch of carelessness slightly in process of production, causes the generation of defective work etc.
Summary of the invention
The purpose of this utility model is that a kind of ball pin cold extrusion die is provided.
To achieve these goals, the utility model is installed respectively patrix outer ring and counterdie outer ring in mould bases inside, counterdie is trapped in counterdie outer ring, the first lower mold core and the second lower mold core are installed respectively in counterdie centre circle, the upper end of push rod is enclosed within the second lower mold core, install core rod in inside, patrix outer ring, insert and be embedded in upper mold core inside.
By above setting, core rod of the present utility model adopts the mounting means decomposing, so not only improve stock utilization, and core rod is if there is wearing and tearing or breaking, only core rod is changed, improved the utilization rate of mould, reduced because of core rod appearance wearing and tearing or the waste product producing that breaks, improve production efficiency, ensured the quality of product.
Brief description of the drawings
Now by reference to the accompanying drawings the utility model is described further.
Fig. 1 is structural representation of the present utility model.
In figure: 1, mould bases, 2, patrix outer ring, 3, counterdie outer ring, 4, counterdie centre circle, 5, the first lower mold core, 6, the second lower mold core, 7, push rod, 8, upper mold core, 9, insert.
Detailed description of the invention
As shown in Figure 1, the utility model is installed respectively patrix outer ring 2 and counterdie outer ring 3 in mould bases 1 inside, counterdie centre circle 4 is enclosed within counterdie outer ring 3, in interior the first lower mold core 5 and the second lower mold core 6 of installing respectively of counterdie centre circle 4, the upper end of push rod 7 is enclosed within the second lower mold core 6, install core rod 8 in 2 inside, patrix outer ring, inserting 9 is embedded in upper mold core 8 inside.
By above setting, after mould bases 9 is connected with equipment, patrix outer ring 2 separates with counterdie outer ring 3, cylindrical iron charge is put in the first lower mold core 5 and the second lower mold core 6, then make patrix outer ring 2 and the cylindrical iron charge of counterdie outer ring 3 crushing failure at high speed by equipment, realize the one-shot forming of ball pin, after machine-shaping, push rod 7 ejects ball pin from the first lower mold core 5 and the second lower mold core 6.
