A first upper die comprises a punch casing and a movable punch arranged in a punch casing cavity, a first lower die is arranged in a cavity of a worktable, a drawing die is arranged at a core of the first lower die, a flange screw rod cavity is arranged at the center of the drawing core, a second punch is arranged on a second upper die, a flange screw head forming sizing unit is arranged at the end of the second punch, a flange screw rod-shaped cavity is formed at the core of the second lower die, a third punch is arranged on the third upper die, a flange screw head structure is formed at the top end of the third punch, and a flange screw rod shaped cavity and a tail cavity are both formed at the core of the third lower die. The flange screw heads processed by the production form of three-die three-punch are quite plumped, quality of the flange screws is guaranteed, a spanner used for operating the flange screws can not be slip off, and tails of the flange screws are machined simultaneously, thereby increasing production efficiency.
Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of flange screw head forming mould, belongs to the precision machinery technology field.
Background technology
Existing flange screw mostly is the mode of dashing by a mould two hexagonal of flange head screw is charged and attacked out, and the hexagonal of the flange screw head that this kind mode of production is produced is not full, in use, causes spanner to skid easily.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of flange screw head forming mould with full hexagonal structure of producing.
The utility model is achieved through the following technical solutions:
A kind of flange screw head forming mould, it is characterized in that, comprise three groups of corresponding up and down upper die and lower die that are provided with, promptly comprise first patrix and first counterdie, second patrix and second counterdie, the 3rd patrix and the 3rd counterdie, wherein, first patrix comprises towards shell and the activity that is arranged in the shell mould chamber and dashing, and first counterdie is arranged in the die cavity of board, its mould heart is provided with movable towards corresponding pumping mode, the center of pumping mode is the die cavity of flange lead screw portion, second patrix is provided with second drift, the end of second drift is provided with the sizing of flange screw head moulding, the mould heart of second counterdie then is formed with the die cavity of flange lead screw portion shape, the 3rd patrix is provided with the 3rd drift, the top of the 3rd drift forms the flange screw head structure, and the core rod of the 3rd counterdie is formed with the die cavity of flange lead screw portion shape, is formed with the die cavity of flange lead screw portion Beam End simultaneously.
The beneficial effects of the utility model are: the head of the flange screw that the mode that the utility model dashes by three moulds three is produced is very full, has guaranteed quality, and spanner can not skid when the flange screw is operated; But also can simultaneously the Beam End structure of flange screw be produced, less operation has improved production efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
Fig. 1 is the overall structure schematic diagram of the utility model one embodiment.
As shown in Figure 1: flange screw head forming mould, comprise three groups of corresponding up and down upper die and lower die that are provided with, promptly comprise the first patrix 1a and the first counterdie 1b, the second patrix 2a and the second counterdie 2b, the 3rd patrix 3a and the 3rd counterdie 3b, wherein, the first patrix 1a comprises towards shell 1c and the activity in the shell 1c die cavity of being arranged on towards 1d, and the first counterdie 1b is arranged in the die cavity of board, its mould heart is provided with and the movable corresponding pumping mode 1e of dashing, the center of pumping mode 1e is the die cavity of flange lead screw portion, the second patrix 2a is provided with the second drift 2c, the end of the second drift 2c is provided with the sizing 2d of flange screw head moulding, the mould heart of the second counterdie 2b then is formed with the die cavity of flange lead screw portion shape, the 3rd patrix 3a is provided with the 3rd drift 3c, the top of the 3rd drift 3c forms the flange screw head structure, and the core rod of the 3rd counterdie 3d is formed with the die cavity of flange lead screw portion shape, is formed with the die cavity of flange lead screw portion Beam End simultaneously.
Fig. 2 is first patrix described in the utility model and the first counterdie structural representation.
As shown in Figure 2: we know, the head materials of flange screw are many, so in the utility model, what use on the first patrix 1a is movable towards 1d, the movable shell 1c that dashes towards 1d cooperation activity once beats the flange screw head materials enough, wire rod is not easy to crack like this, metal flow is to evenly, simultaneously can satisfy the head materials again, the first counterdie 1b is directly installed on board die cavity the inside because relatively many of head materials, usefulness be half dental floss material, so the first counterdie 1b adopts the structure of pumping mode 1e, half dental floss is pumped into full dental floss to satisfy the demand of road, back molding procedure.
Fig. 3 is second patrix described in the utility model and the second counterdie structural representation.
As shown in Figure 3: the end of the second drift 2c on the second patrix 2a described in the utility model is provided with a sizing 2d, the second drift 2c is first with head preformed when work, and the second counterdie 2b adopted the form of mould to rise earlier through the mould material of the first patrix 1a and the first counterdie 1b greatly, increase near the size of grinding the tooth footpath, for last preparation is done in last procedure moulding.
Fig. 4 is the 3rd patrix described in the utility model and the 3rd counterdie structural representation.
As shown in Figure 4: the 3rd drift 3c described in the utility model is directly with the flange screw head extrusion modling, like this by preceding two procedures, the mould stub bar portion that the 3rd drift 3c pushes out can be very full, and the 3rd counterdie 3b also can be up to Beam End directly with the moulding of flange lead screw portion simultaneously simultaneously.
Easy to operate, the high efficiency of the utility model, and the head of the flange screw of producing is full, can prevent effectively that spanner from skidding when operating with the flange screw.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
