Description
Technical field
The present invention relates to the manufacturing process of golden extrusion die, more particularly to a kind of porous Al alloy squeezes pipe and shunts mold
Manufacturing process.
Background technology
In production, tradition of the upper mold reserved margin with mould is generally used to make the manufacturing process of aluminium alloy extruded shunting mold
Technique is made, that is, work band size reserves 0.1-0.3mm surpluses when finishing upper mold, and detection actual wall is then repeatedly assembled by pincers worker
Thick deviation removes surplus or modified manufacturing process again.Although this technique can correct die hole location caused by wire cutting lower die
Deviation leads to the defect of wall thickness dimension inaccuracy, but the actual size of upper mold core print and round degree are difficult to protect when processing pipe mould
Card, therefore the wall thickness tolerance of die hole is unable to time processing qualification.
Invention content
The present invention is intended to provide a kind of manufacturing process of extrusion die, from optimization process is various with removal artificial interference
Hand realizes that core print and mold hole dimension finishing are primary, and pincers worker, which is only assembled, can once match mould success.
