Abstract
The utility model discloses a mold, which comprises a middle mold, an upper blanking mold and a lower blanking mold, wherein the center of the middle mold is provided with a middle mold hole, the upper blanking mold is inserted into the middle mold hole from the upper side of the middle mold, the lower blanking mold is inserted into the middle mold hole from the lower side of the middle mold, a gap is formed between the blanking surface of the upper blanking mold and the blanking surface of the lower blanking mold for forming a die cavity, a plurality of upper blanking mold holes are arranged on the upper blanking mold, lower blanking mold holes in one-to-one correspondence with the upper blanking mold holes are arranged on the lower blanking mold, the mold comprises a plurality of core rods, and each core rod is respectively sheathed into a corresponding lower blanking mold hole and is inserted into the corresponding upper blanking mold hole after passing through the middle mold hole. The utility model has the advantages of simple structure and convenient operation, and is applicable to blanking elements with two center holes.
Description
Technical field:
The utility model relates generally to a kind of mould.
Background technology:
When using stamping machine to carry out punching press, a cover diel all can be installed in it, every cover diel correspondence stamps out a kind of part.The stamping parts that has has two centre bores, the diel supporting with it realize punch forming.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of mould to be provided, and it is applicable to the stamping parts that has two centre bores.
The utility model is achieved through the following technical solutions:
A kind of mould, it is characterized in that: include middle mould, upper trimming die and following punch die, the mould center has middle nib in described, described upper trimming die therefrom mould upside inserts in the described middle nib, described down punch die is during therefrom the mould downside inserts in the nib, leave the space between the stamping surface of the stamping surface of described upper trimming die and following punch die and form die cavity, have some upper punch nibs on the described upper trimming die, have with the upper punch nib on the described punch die down and descend one to one the punch die hole, include some plugs, each plug is inserted in respectively in the corresponding following punch die hole and in passing and inserts in the corresponding upper punch nib behind the nib.
Described a kind of mould, it is characterized in that: have two upper punch nibs on the described upper trimming die, have with the upper punch nib on the described punch die down and descend one to one the punch die hole, include two plugs, each plug is inserted in respectively in the corresponding following punch die hole and in passing and inserts in the corresponding upper punch nib behind the nib.
The course of work of the present utility model is as follows: earlier fill metal dust in the middle nib of middle mould, start upper trimming die and following punch die more simultaneously, in making upper trimming die therefrom the mould upside inserting in the nib, following punch die is therefrom in the insertion of mould downside in the nib.At this moment, the stamping surface of upper trimming die pushes it from the metal dust upside, and following punch die stamping surface pushes it from the metal dust downside.Because the upper and lower both sides of metal dust are extruded simultaneously, make it be compressed in extrusion modling in the die cavity.At last, start plug, make plug be inserted in down punch die up and down in the punch die hole and in passing behind the nib in the insertion upper punch nib, like this, in forming part, be formed centrally centre bore.
The utility model has the advantages that:
The utility model is simple in structure, easy to operate, is applicable to the stamping parts that has two centre bores.
Description of drawings:
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.
The specific embodiment:
A kind of mould, mould 1 in including, upper trimming die 2 and following punch die 3, nib 4 during mould 1 center has in described, described upper trimming die 2 therefrom mould 1 upside inserts in the described middle nib 4, described down punch die 2 is during therefrom mould 1 downside inserts in the nib 4, leave the space between the stamping surface of the stamping surface of described upper trimming die 2 and following punch die 2 and form die cavity, have two upper punch nibs 5 on the described upper trimming die 2, have with upper punch nib 5 on the described punch die 3 down and descend one to one punch die hole 6, include two plugs 7, every plug 7 is inserted in respectively in the corresponding following punch die hole 6 and in passing and inserts in the corresponding upper punch nib 5 behind the nib 4.
