The specific embodiment
The utility model provides a kind of porous magnesium alloy pipe extrusion die, comprises patrix 1 and counterdie 2, and patrix 1 is connected with counterdie 2.
As Figure 1-3, patrix 1 is flat cylindrical shape, and patrix 1 is provided with six charging apertures 11, offers between 111, two tap holes 111 of two tap holes and be provided with shunting bridge 112 on charging aperture 11, on shunting bridge 112, is fixedly connected with shaping column 12.The end face that patrix 1 is provided with shaping column 12 is provided with male half coupling 13, and shaping column 12 protrudes from male half coupling 13.Shunting bridge 112 is provided with the first seam chamber 14 with shaping column 12 junctions.
As Figure 4-Figure 6, counterdie 2 is flat cylindrical shape, and patrix 1 is identical with the size of counterdie 2.Counterdie 2 is provided with recessed seam 21, the second seam chamber 22, forming hole 23 and discharging opening 24 successively.Counterdie 2 is provided with six discharging openings 24, and six discharging openings 24 of counterdie 2 are corresponding one by one with six charging apertures 11 of patrix 1.Each discharging opening 24 has corresponding with it forming hole 23 and the second seam chamber 22.The end face that counterdie 2 is connected with patrix 1 is provided with recessed seam 21, and the recessed seam 21 of counterdie 2 cooperatively interacts with the male half coupling 13 of patrix 1.The male half coupling of patrix 1 13 is fastened in the recessed seam 21 of counterdie 2, thereby patrix 1 and counterdie 2 are coupled together.The second seam chamber 22 is corresponding with 14 positions, the first seam chamber.Counterdie 2 is provided with forming hole 23.Shaping column 12 is set in forming hole 23 through the first seam chamber 14 and the second seam chamber 22.The length of shaping column 12 is greater than the length of forming hole 23, is conducive to the moulding of magnesium alloy pipe, prevents that the through hole of magnesium alloy pipe is out of shape under the extruding of forming hole 23.The external diameter of shaping column 12 is less than the internal diameter of forming hole 23.The big or small gap of the external diameter of shaping column 12 and forming hole 23 internal diameters is the thickness of magnesium alloy pipe.The magnesium alloy materials that is squeezed out endoporus at patrix 1 by shaping column 12 squeezes out the profile of magnesium alloy materials by forming hole 23, thereby forms complete magnesium alloy pipe, then the discharging opening 24 by counterdie 2 out.The discharging opening 24 of counterdie 2 is stepped, and the bore of discharging opening 24 becomes greatly gradually, facilitates the discharging of magnesium alloy pipe.
As shown in Figure 7, patrix 1 is provided with four the first dowel holes 15, and counterdie 2 is provided with four the second dowel holes 25.When fixing patrix 1 and counterdie 2, rotation patrix 1 and counterdie 2, make the first dowel hole 15 corresponding with the position of the second dowel hole 25.Patrix 1 and counterdie 2 are fixed by alignment pin, and alignment pin is through the first dowel hole 15 and the second dowel hole 25.The first dowel hole 15 is blind hole, and the second dowel hole 25 is through hole, and the end face that alignment pin is provided with discharging opening 24 from counterdie 2 pierces into the second dowel hole 25, successively through the second dowel hole 25 and the first dowel hole 15, thereby patrix 1 and counterdie 2 is fixed.Patrix 1 is provided with 16, the first suspension ring holes 16, two the first suspension ring holes and the vertical setting of the first dowel hole 15.Counterdie 2 is provided with 26, the second suspension ring holes 26, two the second suspension ring holes and the vertical setting of the second dowel hole 25.The effect in the first suspension ring hole 16 of patrix 1 and the second suspension ring hole 26 of counterdie 2 is that patrix 1 and counterdie 2 is fixing.
The raw material magnesium alloy being heated to soften enters in the tap hole 111 of patrix 1 charging aperture 11, by shunting bridge 112, be divided into two parts magnesium alloy materials, two parts magnesium alloy materials envelopes shaping column 12, shaping column 12 forms through hole in magnesium alloy materials, two parts magnesium alloy materials being divided into by shunting bridge 112 fully mixes in the space of the first seam chamber 14 and the second seam chamber 22 compositions, forms tubulose.The magnesium alloy barred body that is squeezed out through hole is by the forming hole 23 of counterdie 2, at the interior formation magnesium alloy pipe of forming hole 23, from the discharging opening 24 of counterdie 2 out.
By reference to the accompanying drawings embodiments more of the present utility model are described in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from aim of the present invention, make various variations.
