The utility model can stably produce a fully enwrapped die core aluminum profile with good size and wall thickness, low production cost and longer service life.
Description
(1) technical field
The utility model relates to a kind of aluminium section hot-extrusion die.Be mainly used in the hot extrusion that core rod is little and one of them core rod is all surrounded the full encirclement formula core rod class aluminium section bar of (to call " surrounding the formula core rod entirely " in the following text) by other core rod.Belong to the mold machining technology field.
(2) background technology
Because the high speed development of aluminum products process technology, the client is also more and more higher to the requirement of product, and product also presents diversification, complicated, particularization.The industry that aluminum products relate to is also innumerable.Wherein porous aluminum section bar (see figure 9) is also more and more, and porose aluminium section bar also begins corresponding more and more in the hole.The mould design of this type of section bar is difficulty (particularly little mould) relatively, should guarantee the aluminium that supplies between core rod, guarantees not bullet change of core rod again, does not rupture, and also will guarantee processing and put in place.If quite low according to conventional design scheme (patrix monoblock type) success rate, processing is difficulty not only, and is difficult to put in place by design idea processing.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can stably produce size and wall thickness is good, production cost is low, service life is long full encirclement formula core rod class aluminium section hot-extrusion die.
The purpose of this utility model is achieved in that a kind of full encirclement formula core rod class aluminium section hot-extrusion die, comprise upper die and lower die, the charging face of patrix is evenly equipped with several tap holes, the charge level that goes out of patrix is provided with several core rods, described counterdie charging face is provided with seam chamber and die cavity, it is characterized in that:
Described patrix is divided into symmetrical two parts, the center of described patrix is provided with a lock pin hole, be inserted with lock pin in this lock pin hole, this lock pin and described lock pin hole interference fit, be combined into common core rod, go out with patrix again that other core rod inserts in the die cavity of described counterdie on the charge level
Described core rod is distributed in the periphery in described lock pin hole, and the outside of described core rod is provided with oblique protection, is provided with material guide groove between described core rod.
To the core rod of patrix and the die cavity of following film, aluminium stream is undertaken being extruded synchronously with the aluminium stream of counterdie die cavity after aluminium stream is filled by the empty cutter of material guide groove between the patrix core rod and counterdie discharge opening the tap hole of the utility model process patrix when aluminium bar contact patrix with the aluminium conductance.Thereby obtain qualified goods.
The utility model has been Duoed a lock pin than common mould.Its purpose is that an original patrix is divided into two partly processes assembling again.Abbreviate.Be same as common patrix after the assembling.Assemble with counterdie again.Can solve well like this processing of common patrix less than the place, solve the problem that full encirclement formula core rod class section bar is produced difficulty.And can protect many core rods to greatest extent, and the outside of patrix core rod is all designed oblique protection and is guaranteed the stable of other core rod.Guarantee the feed of reinforcement between core rod again from the material guide groove of the design certain angle and the degree of depth between core rod.Therefore can stably produce size and the full encirclement formula core rod class aluminium section bar that wall thickness is good, production cost low, grow service life.
