Abstract
The utility model relates to a kind of production mould of aluminium section bar, particularly relates to low extrusion ratio mould.Comprise the first patrix, the second upper die and lower die, the first described patrix is provided with at least two tap holes, the second described patrix is provided with core rod and at least two conduction holes, and described counterdie is provided with drainage face, and described drainage face forms the angle of 110 ° ~ 130 ° with the top surface of counterdie.This mould is owing to being provided with drainage face, and drainage face is at a certain angle with the top surface shape of counterdie, perfectly achieve the production of section bar of wall thickness, inner hollow, section bar reaches production standard not need to adopt too large extruding force just can ensure, lower to the loss of mould, extend the mold use life-span, decrease the production cost of enterprise.
Description
[technical field]
The utility model relates to a kind of production mould of aluminium section bar, particularly relates to the aluminium section bar production mould of extrusion ratio.
[background technology]
Utilize traditional aluminium section bar production mould to produce square, inner hollow, wall thickness aluminium section bar and possess certain difficulty, main cause is that general production mould extrusion ratio requires to reach more than 8, if can cause being difficult to feed lower than this numerical value, the section bar produced does not reach standard.And the aluminium section bar of inner hollow, wall thickness can not adopt too high extrusion ratio, only require and reach 5.5, in therefore traditional production technology, lack a kind of production mould of low extrusion ratio.
[summary of the invention]
The utility model is intended to solve the problem and provide a kind of low extrusion ratio mould.
For achieving the above object, the low extrusion ratio mould of one of the present utility model comprises the first patrix 10, second patrix 20 and counterdie 30, the first described patrix 10 is provided with at least two tap holes 11, the second described patrix 20 is provided with core rod 22 and at least two conduction holes 21, described counterdie 30 is provided with drainage face 31, and described drainage face 31 forms the angle of 110 ° ~ 130 ° with the top surface of counterdie 30.
Further, the angle that described drainage face 31 is formed with the top surface of counterdie 30 is 120 ° ~ 128 °.
Further, the angle that described drainage face 31 is formed with the top surface of counterdie 30 is 126.9 °.
Further, described tap hole 11 inside is larger than aperture.
Further, the quantity of described tap hole 11 is 4.
Further, the quantity of described conduction hole 21 is 4.
Contribution of the present utility model there are provided a kind of low extrusion ratio mould, this mould is owing to being provided with drainage face, and drainage face is at a certain angle with the top surface shape of counterdie, perfectly achieve the production of section bar of wall thickness, inner hollow, section bar reaches production standard not need to adopt too large extruding force just can ensure, lower to the loss of mould, extend the mold use life-span, decrease the production cost of enterprise.

[detailed description of the invention]
The following example is to further explanation of the present utility model and supplements, and does not constitute any limitation the utility model.
Embodiment 1
The low extrusion ratio production mould of one of the present embodiment comprises the first patrix 10, second patrix 20 and counterdie 30, the first described patrix 10 is provided with four tap holes 11, the second described patrix 20 is provided with core rod 22 and four conduction holes 21, described counterdie 30 is provided with drainage face 31, and described drainage face 31 forms the angle of 120 ° with the top surface of counterdie 30.First the mould of the present embodiment installs according to the first patrix 10, second patrix 20 and counterdie order in process of production, aluminium alloy arrives the extrusion position of counterdie 30 by the conduction hole 21 of tap hole 11, second patrix 20 of the first patrix 10, under the acting in conjunction of extruding force, core rod 22 and counterdie 30, be squeezed into section bar.Due to counterdie 30 being provided with drainage face 31, and drainage face 31 and counterdie 30 top surface define the angle of 120 °, too large extruding force is not needed when making aluminium alloy enter into work strip under the effect in drainage face 31, decrease the loss to mould, extend the mold use life-span, do not need often to change, decrease the production cost of enterprise.
Although disclosed the utility model by above embodiment; but protection domain of the present utility model is not limited thereto; under the condition not departing from the utility model design, all will fall in right of the present utility model the distortion, replacement etc. that above each component does.
