Abstract
The invention discloses a ball pin cold extrusion mold. The ball pin cold extrusion mold is characterized in that an upper mold outer ring and a lower mold outer ring are arranged inside a mold frame respectively; a lower mold middle ring is sleeved into the lower mold outer ring; a first lower mold core and a second lower mold core are arranged in the lower mold middle ring respectively; the upper end of an ejector rod is sleeved into the second lower mold core; an upper mold core is arranged inside the upper mold outer ring; an insert is inserted into the upper mold core. According to the ball pin cold extrusion mold, the mold cores are installed in a detachable manner, so that the utilization rate of materials is improved; moreover, the mold cores which are abraded or broken are just replaced, so that the utilization rate of the mold is improved, scraps caused by abrasion or breakage of the mold cores are reduced, the production efficiency is improved, and the product quality is ensured.
Description
Technical field
The present invention 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, carelessness easy generation mismatch just slightly, causes the generation of defective work etc. in process of production.
Summary of the invention
Object of the present invention is that a kind of ball pin cold extrusion die is provided.
To achieve these goals, the present invention installs 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, in inside, patrix outer ring, install core rod, insert and be embedded in upper mold core inside.
By above setting, core rod of the present invention adopts the mounting means decomposing, so not only improved 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 the waste product that weares and teares or break and produce because of core rod appearance, improve production efficiency, guaranteed the quality of product.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
In figure: 1, mould bases, 2, patrix outer ring, 3, counterdie outer ring, 4, counterdie centre circle, the 5, first lower mold core, the 6, second lower mold core, 7, push rod, 8, upper mold core, 9, insert.
The specific embodiment
As shown in Figure 1, the present invention installs 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, in 2 inside, patrix outer ring, install core rod 8, 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 is separated 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 by equipment, make patrix outer ring 2 and the cylindrical iron charge of counterdie outer ring 3 crushing failure at high speed, 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.
