Abstract
The utility model discloses a molding die for a bolt, which comprises a lower die and an upper die. A stepped groove is arranged in the lower die, and a vertically-sliding ejection column is arranged at the center of the bottom of the groove. A stepped protrusion matched with the groove is arranged at the lower portion of the outer wall of the upper die, a die cavity is arranged in the upper die, a hexagonal-prism-shaped sunken groove is arranged at the center of the die cavity, the bottom of the sunken groove is provided with a through hole matched with the support column, a die cover is covered at the upper end of the sunken groove, and a pouring hole communicated with the sunken groove is arranged on the die cover. The molding die for the bolt is reasonable in structural design, cooling is performed through the structure matched with the bolt shape in the upper die after pouring, the bolt is ejected out through the ejection column in the lower die, the structural strength of the bolt is high, the connection process is stable and reliable, and the requirements of the work environment are met.
Description
Technical field:
The utility model relates to the bolt processing technique field, relates in particular to a kind of bolt and uses mould.
Background technology:
Develop rapidly along with national economy; To the production technology of standard component with require increasingly highly, the industry of specific (special) requirements is especially arranged, in the manufacturing like the railway machine of China, visitor, lorry at secure context; Because the raising of road speed; With having higher requirement, such as the traffic safety of fastening force after must satisfying speed-raising of bolt, the high-intensity bolt of so a large amount of different stages has replaced the plain bolt that is adopted in the past to securing member.
At present high-strength bolt be processed with dual mode, a kind of method is special-purpose hexangle type steel processing bolt, another kind of method is to forge blank, carries out machining then, all there are a lot of drawbacks in these two kinds of methods.
Therefore the designer is changed traditional method, design is used shaping jig with bolt, is convenient to make high-intensity bolt.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of bolt and uses mould, and modern design is convenient to make high-intensity bolt, connects the demand that fastening force satisfies actual working environment.
The technical scheme of the utility model is following:
Bolt is used mould, comprises counterdie and patrix, it is characterized in that: be provided with stair-stepping groove in the described counterdie, the bottom centre of groove is provided with the fore-set that slides up and down; Described patrix outer wall bottom is provided with the stair-stepping convexity that matches with groove; Be provided with die cavity in the patrix, the die cavity center is the deep gouge of hexagon, and the deep gouge bottom has the through hole that matches with fore-set; Die cap is stamped in described deep gouge upper end, and die cap is provided with the plug hole that is connected with deep gouge.
Described bolt is used mould, it is characterized in that: described counterdie outer wall both sides are provided with lug, have installing hole on the lug.
The utility model has the advantages that:
The utility model reasonable in design, through being provided with the structure that matches with the bolt profile in the patrix, cool off the cast back, and through the fore-set liftout bolt in the counterdie, bolt arrangement intensity is high, and is reliable and stable in the connection procedure, satisfies the needs of working environment.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Referring to Fig. 1:
Bolt is used mould, comprises counterdie 1 and patrix 2, is provided with stair-stepping groove 3 in the counterdie 1, and the bottom centre of groove 3 is provided with the fore-set 4 that slides up and down; Patrix 2 outer wall bottoms be provided with match with groove 3 stair-stepping protruding 5; Be provided with die cavity in the patrix 2, the die cavity center is the deep gouge 6 of hexagon, and deep gouge 6 bottoms have the through hole 7 that matches with fore-set; Die cap 8 is stamped in deep gouge 6 upper ends, and die cap 8 is provided with the plug hole 9 that is connected with deep gouge 6.
Counterdie 1 outer wall both sides are provided with lug 10, have installing hole 11 on the lug 10.
The utility model raw material must be annealed, pickling, phosphatization are handled, and help to protect mould, prolong die life, and the utility model makes the head and the one-shot forming of bar portion of bolt, and specious, intensity improves greatly.
Claims (2)
1. a bolt is used mould, comprises counterdie and patrix, it is characterized in that: be provided with stair-stepping groove in the described counterdie, the bottom centre of groove is provided with the fore-set that slides up and down; Described patrix outer wall bottom is provided with the stair-stepping convexity that matches with groove; Be provided with die cavity in the patrix, the die cavity center is the deep gouge of hexagon, and the deep gouge bottom has the through hole that matches with fore-set; Die cap is stamped in described deep gouge upper end, and die cap is provided with the plug hole that is connected with deep gouge.
