Abstract
The invention discloses a die for extruding large-section aluminium alloy sections with easily-broken close teeth. The die comprises a core and a die sleeve, wherein a forming cavity is arranged in the core; a core fixed groove and a discharging cavity are arranged in the die sleeve; the core is fixedly inlaid in the core fixed groove; and the forming cavity is communicated with the discharging cavity. The die has the following benefits: the core and the die sleeve of the die adopt the small-gap inlaying fitting, so that the assembly is convenient; after the core loses efficacy due to breakage, the core is taken out from the die sleeve, and the production can be continued by replacing a new core, so that the die steel material cost caused by the die damage can be greatly reduced.
Description
Technical field
The present invention relates to mould manufacturing field, relate in particular to a kind of for pushing the mould of the easily broken large section aluminium alloy extrusions of close tooth.
Background technology
Aluminium alloy extruded material obtains application more and more widely in every field, is a kind of high added value aluminum alloy materials.In recent years, aluminium alloy extruded material has obtained fast development at field of radiating, need complex-shaped, close tooth in a large number, tongue than the external import of the many dependence of aluminium alloy extruded material large, wall thickness dimension great disparity is large aluminium alloy extruded Cai，Dan China, or can only process in Taiwan, produce.Because this aluminium alloy extruded material has that close tooth, wall thickness dimension great disparity are large, tongue is than large top grade, its production mould is not only difficult for processing, and service life is short, easily fracture, production cost is higher.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of for pushing the mould of the easily broken large section aluminium alloy extrusions of close tooth, and easily broken, the easy inefficacy part of pattern is separated to independent processing from pattern, during use, core is mounted in pattern cover.This mould structure is easy to processing, realizes at circular cross section extrusion dies such as bars, and for aluminium extrusion material for flat wide close tooth radiator, its technical difficulty is just much bigger.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of for pushing the mould of the easily broken large section aluminium alloy extrusions of close tooth, comprise core and pattern cover, in described core, be provided with forming cavity, in described pattern cover, be provided with core holddown groove and discharging chamber, core is inlayed and is fixed in described core holddown groove, and described forming cavity and discharging chamber are communicated with.
Wherein, in the bottom of described core holddown groove, be provided with through hole, described through hole is symmetrically arranged in described discharging Qiang both sides, and its quantity is 4 to 6.
The invention has the beneficial effects as follows: the core of mould and pattern cover adopt the closely spaced cooperation of inlaying, easy to assembly, when core fracture and after losing efficacy, only core need be taken out from pattern cover, change new core and can put into production again, can significantly save the die steel material cost producing because of mould damage.

The specific embodiment
By describing technology contents of the present invention, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1 to Fig. 6, present embodiment is a kind of for pushing the mould of the easily broken large section aluminium alloy extrusions of close tooth, comprises core 10 and pattern cover 20.In described core 10, be provided with forming cavity 11, on forming cavity 11, be provided with close tooth 12.In described pattern cover 20, be provided with core holddown groove 21 and discharging chamber 22, core 10 is inlayed and is fixed in described core holddown groove 21, and described forming cavity 11 and discharging chamber 22 are communicated with.
Wherein, in the bottom of described core holddown groove 21, be provided with through hole 23, described through hole 23 is symmetrically arranged in described discharging Qiang22 both sides, and its quantity is 6.When needs are more talked about core 10, only stock need be stretched into from these 6 through holes 23, core 10 is ejected, reinstall new core 10.
The production of present embodiment comprises following precision and controls:
In the processing of core, in the margin of tolerance of be controlled at-0.02mm to 0mm of overall precision, core and pattern cover are inlayed the be controlled at-0.04mm of bight precision of part to the margin of tolerance of-0.02mm, and the thickness and precision of core is controlled in the margin of tolerance of 0mm to 0.05mm;
In the processing of pattern cover, overall precision is controlled in the margin of tolerance of 0mm to 0.02mm, the bight precision that core holddown groove and core are inlayed part is controlled in the margin of tolerance of 0mm to 0.02mm, in the margin of tolerance of the be controlled at-0.05mm to 0mm of thickness and precision of pattern cover.
The invention has the beneficial effects as follows: the core of mould and pattern cover adopt the closely spaced cooperation of inlaying, easy to assembly, when core fracture and after losing efficacy, only core need be taken out from pattern cover, change new core and can put into production again, can significantly save the die steel material cost producing because of mould damage.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
