Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a breather pin 1 for optimize 2 exhaust system's of mould exhaust mode, improve the yields and the shaping efficiency of mould 2 in casting or injection moulding process, it is shown according to attached figure 1-attached figure 3, concrete structure includes:
the through holes 11 are provided with a plurality of through holes 11, each through hole 11 penetrates through the vent pin 1, the through holes 11 are regularly arranged on the vent pin 1, the through holes 11 penetrate through the vent pin 1 and are arranged in a hexagonal edge shape according to the attached drawing 2, each through hole 11 extends from a first end to a second end of the vent pin 1, the distance from the first end to the second end of the vent pin 1 is 10mm, and each through hole penetrates through the distance to the other end, so that the whole interior of the vent pin 1 is hollow, and the through holes 11 arranged in a regular mode are beneficial to exhaust in a mold cavity of the mold 2 in the casting process of nonferrous metals such as copper, aluminum alloy and the like or other alloys and exhaust of a grave in the injection molding process.
The pore diameter of each through hole 11 is 0.3-0.5 mm, and the air permeability of the exhaust of the die 2 can reach 3000-3500 by the pores of 0.3 and 0.5; and the through hole 11 is polished, so that the problem that residues exist in pores of the vent pin in the sintering process is solved, the exhaust performance of the vent pin 1 is improved, and the exhaust effect of the mold 2 is improved.
The vent pin 1 and the butt joint part 12 are made of non-magnetic stainless steel, the non-magnetic stainless steel is adopted, the corrosion resistance and the thermal fatigue resistance are good, and the service life of the vent pin 1 is prolonged; it is also avoided that metal debris is absorbed in the exhaust system during casting of the casting mould 2, thereby causing the mould 2 to gradually influence the exhaust of the mould 2 during use.
And an abutting part 12, wherein the abutting part 12 is arranged at the first end of the vent pin 1 body, and/or the second end, the distance from the first end to the second end of the abutting part 12 is 1.5mm, the through hole 11 penetrates through the abutting part 12, one end of the abutting part 12 is gradually enlarged towards the other end, specifically, the outermost end is slightly smaller, and the end is used for being connected with the casting mold 2 or the injection mold 2 according to the figure 3, so that the through hole 11 of the vent pin 1 is communicated with the filling cavity.
