Abstract
The utility model discloses a forging mold ejector beam and an ejector hole structure of the forging mold ejector beam. The forging mold ejector beam and the ejector hole structure of the forging mold ejector beam comprise a mould. An ejector hole is arranged in the middle of the mould. An ejector beam is arranged in the ejector hole in match. The forging mold ejector beam and the ejector hole structure of the forging mold ejector beam are characterized in that the upper end portion of the ejector hole is a stepped hole, the upper end of the stepped hole is a hole of large diameter and the lower end of the stepped hole is a hole of small diameter, and the transition portion of the stepped hole is connected and matched with an inclined plane to form an inverted-cone hole. The lower end of the ejector beam is arranged in the hole of small diameter of the stepped hole in a matched mode. The upper portion of the ejector beam is provided with an inverted-cone platform installed in the inverted-cone hole in a matched mode. The forging mold ejector beam and the ejector hole structure of the forging mold ejector beam are stable in shape and size, small in mould damage, and easy to assemble and replace.
Description
Technical field
The utility model relates to the forging die field, relates in particular to a kind of forging die ejector beam and liftout pore structure thereof.
Background technology
In the existing forging die, its ejector beam is simple in structure, mostly is the straight-bar type structure, and in use ejector beam is yielding, stuck, size is unstable, and the suffered hitting power of ejector beam is delivered to mould bases simultaneously, make the mould bases local deformation, and the dress mould to join ejector beam cumbersome, can not satisfy instructions for use.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of forging die ejector beam and liftout pore structure thereof are provided, it is simple in structure to have solved existing ejector beam, in use ejector beam is yielding, stuck, size is unstable, and the suffered hitting power of ejector beam is delivered to mould bases simultaneously, make the mould bases local deformation, and the dress mould is joined the problems such as ejector beam is cumbersome.
The utility model is achieved through the following technical solutions:
A kind of forging die ejector beam and liftout pore structure thereof, include mould, the middle part of described mould is provided with the liftout hole, cooperate in the described liftout hole ejector beam is installed, it is characterized in that: the upper end in described liftout hole is stepped hole, the upper end of described stepped hole is large diameter hole, the lower end is small diameter bore, and the transition position of stepped hole connects by the inclined-plane and cooperates the formation reverse taper hole, the lower end of described ejector beam cooperates installation with the small diameter bore of stepped hole, the upper end is provided with the back taper platform, and described back taper platform cooperates installation with reverse taper hole.
The deviation angle of described reverse taper hole and large diameter hole is 15-60 °.
The height of described back taper platform is less than or equal to the height with reverse taper hole.
Its principle is: by the back taper platform in ejector beam and liftout hole and the structural design of reverse taper hole, the suffered hitting power of ejector beam all can be delivered to mould, main force part is apart from weak point, it is more stable to be difficult for the distortion size, less to the mould bases damage, be easy to simultaneously assembling, be convenient for changing.
The utility model has the advantages that:
1. be easy to assembling, be convenient for changing.
2. the suffered hitting power of ejector beam all is delivered to mould, and main force part is apart from weak point, and it is more stable to be difficult for the distortion size.
3. less to the mould bases damage.
Description of drawings
Fig. 1 is the utility model blast structural representation.
The specific embodiment
Referring to accompanying drawing, a kind of forging die ejector beam and liftout pore structure thereof, include mould 1, the middle part of mould 1 is provided with liftout hole 2, cooperate in the liftout hole 2 ejector beam 3 is installed, the upper end in liftout hole 2 is stepped hole, the upper end of stepped hole is large diameter hole, the lower end is small diameter bore, and the transition position of stepped hole connects by the inclined-plane and cooperates formation reverse taper hole 4, the lower end of ejector beam 3 cooperates installation with the small diameter bore of stepped hole, and the upper end is provided with back taper platform 5, and back taper platform 5 cooperates installation with reverse taper hole 4; Reverse taper hole 4 is 15-60 ° with the deviation angle of large diameter hole; The height of back taper platform 5 is less than or equal to the height with reverse taper hole 4.
Claims (3)
