Abstract
The invention relates to a small round aluminum alloy thermal squeeze mold that comprises the top mold and the bottom mold whose inner hole wall dotted with alloy interior liner under the bottom mold welding chamber, the said top mold having two separation flow holes, middle of the top mold radially set a horizontal bar shape bridge, two separation flow holes set at both sides of the bridge, connected to the upper mold alloy inlaid parquet, bridge with the fitting face of the bottom mold welding chamber forming into a top mold setting bridge which is the top mold welding chamber, the top mold alloy inlaid parquet inserted into the alloy inner liner of the bottom mold to form the overall cavity inside the section bar. It not only improves production efficiency, but also reduces production cost, also ensuring welding quality.
Description
Technical field
The present invention relates to a kind of mould, especially relate to a kind of pipe aluminium alloy section bar heat extruding mold.Be mainly used in the hot extrusion of roundlet pipe aluminium alloy extrusions.Belong to the mold machining technology field.
Background technology
Along with the needs of market development, the requirement of small round tube aluminium alloy section bar is increasing, and the requirement of section bar seam line is more and more higher, and section bar wall thickness tolerance is more and more tighter, and require more and more higher die life, and extrusion speed requires more and more faster.But section bar manufacturer often adopts the extruder of little tonnage to squeeze small round tube aluminium alloy section bar at present, and the phenomenon that ubiquity efficient is not high, production cost is high mainly shows:
1, the seam chamber all is arranged on the counterdie, and mould specification is big, and the used material of mould is many, the die cost height;
2, can only realize the extruding of " goes out ", extruding force is big, and production efficiency is low;
3, two above bridge locations are arranged, the seam line of section bar has three or four, and the welding quality line of section bar is not high;
4, upper and lower mould all adopts same material, and the wearability of die working length is relatively poor, and the service life of single mold is short, yields poorly.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of and not only can improve section bar factory production efficiency, but also can reduce section bar factory production cost, also can guarantee the small round tube aluminium alloy section bar heat extruding mold of section bar welding quality simultaneously.
The object of the present invention is achieved like this: a kind of small round tube aluminium alloy section bar heat extruding mold, comprise upper die and lower die, it is characterized in that: described counterdie crown center is concaved with counterdie seam chamber downwards, is inlaid with counterdie alloy lining cover on the counterdie endoporus hole wall of below, counterdie seam chamber; Described patrix top is provided with two tap holes, and patrix top intermediate radial is provided with " one " font bridge location, and two tap holes are divided into the left and right both sides of bridge location, are connected with the patrix alloy under the bridge location and insert; The mating surface place of bridge location and counterdie seam chamber sinks to forming the heavy bridge place of patrix, the zone at the heavy bridge place of this patrix is patrix seam chamber, patrix seam chamber and counterdie seam chamber constitute the whole seam chamber of mould, and the patrix alloy of the patrix part of inserting is inserted the whole die cavity that constitutes section bar in the counterdie alloy lining cover of counterdie.
The present invention adopts the version of " primary and secondary mould ", can be implemented in and assemble two or more " submodule tools " in the die sleeve simultaneously, reach the state of " goes out two " or " go out several ", reduce the product moulding extruding force, improve the purpose of section bar production efficiency thereby reach.
Compare with existing similar mould, the present invention has following advantage:
1, the seam chamber some be arranged on the counterdie, some is arranged on the patrix, mould specification can dwindle, and can significantly reduce the used material of mould, reduces die cost;
2, can realize the extruding of " goes out two " or " go out several ", reduce extruding force, enhance productivity;
3, adopt the version of " one " word bridge, have only two bridge locations, the seam line of section bar also only has two, is less than three or four of other mould, and the welding quality of section bar improves;
4, adopt the structure of upper and lower mould edge alloy, improve the wearability of die working length, thereby reach the purpose that improves single mold output.
