Abstract
The invention relates to a magnesium alloy die casting machine, which comprises a cavity body and an injection body. A feeding hole is arranged on the cavity body. A piston is arranged in the cavity body. A gooseneck is arranged at the outlet of the cavity body. The gooseneck and the injection body are connected in a matched manner. An intermediate-frequency heating pipe is arranged on the periphery of the gooseneck. A resistance wire is arranged on the periphery of the injection body. The resistance wire is uniformly wound on the outer wall of the injection body. A transition sleeve is arranged between the gooseneck and the injection body. A through hole is in the centre of the transition sleeve. According to the magnesium alloy die casting machine disclosed by the invention, because the transition sleeve is additionally arranged between the gooseneck and the injection body, a molten magnesium alloy solution is more smooth in the process of flowing through the gooseneck and the injection body, and the seam which is easy to cause the magnesium alloy solution to overflow is effectively prevented; meanwhile, because a heating component is arranged, the heat deformation amplitude of the injection body is matched with the heat deformation amplitude of the gooseneck, the magnesium alloy solution can be more effectively prevented from overflowing through the joint, and the normal high-efficiency operation of the magnesium alloy die casting machine is facilitated.

According to another embodiment of the invention; It is corresponding with the molten magnesium alloy leadout hole diameter of gooseneck that a kind of magnesium alloy pressure casting machine comprises that further said spacer shell is positioned at the through-hole diameter of first end of gooseneck side, and the through-hole diameter that spacer shell is positioned at second end of penetrating the body side is corresponding with the molten magnesium alloy entrance hole diameter of penetrating body.
According to another embodiment of the invention, a kind of magnesium alloy pressure casting machine further comprise said gooseneck molten magnesium alloy leadout hole diameter greater than the molten magnesium alloy entrance hole diameter of penetrating body.
According to another embodiment of the invention; A kind of magnesium alloy pressure casting machine comprises that further the molten magnesium alloy leadout hole end of said gooseneck is provided with first heavy stand; The said molten magnesium alloy entrance hole head end of penetrating body is provided with second heavy stand; Said first heavy stand matches with first end of spacer shell, and said second heavy stand matches with second end of spacer shell.
According to another embodiment of the invention, a kind of magnesium alloy pressure casting machine comprises that further said heating element heater is a resistance wire.
According to another embodiment of the invention, a kind of magnesium alloy pressure casting machine comprises that further said resistance wire uniform winding penetrating the body outer wall.
Magnesium alloy pressure casting machine of the present invention; Through at gooseneck and penetrate between the body to increase spacer shell is set; And the through-hole diameter that makes this spacer shell matches with the molten magnesium alloy leadout hole diameter of gooseneck and the molten magnesium alloy entrance hole diameter of penetrating body respectively; Make the magnesium alloy solution of fusion at the gooseneck and more smooth and easy when penetrating body of flowing through, effectively prevented to be prone to cause the generation of the seam that magnesium alloy solution overflows; Simultaneously through heating element heater is set; Can realize that independent correlation body heats; And then control penetrate body the thermal deformation amplitude; Thereby the thermal deformation amplitude of penetrating body is matched with the thermal deformation amplitude of gooseneck, avoided magnesium alloy solution to overflow more effectively, help working normally and efficiently of magnesium alloy pressure casting machine from gaping of joints.

The specific embodiment
Combine accompanying drawing and preferred embodiment that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Like Fig. 1, a kind of magnesium alloy pressure casting machine shown in Figure 2, comprise cavity 1, penetrate body 2, said cavity 1 is provided with charging aperture 3; Be provided with piston 4 in the cavity 1, cavity 1 outlet is provided with gooseneck 5, said gooseneck 5 with penetrate body 2 and be connected; Said gooseneck 5 outer periphery are equipped with heating in medium frequency pipe 6; Said body 2 outer periphery of penetrating are equipped with heating element heater 7, and said heating element heater 7 is a resistance wire, and said resistance wire uniform winding is being penetrated body 2 outer walls; Said gooseneck 5 and penetrate and be provided with spacer shell 8 between the body 2, said spacer shell 8 centers are through hole 9.
The through-hole diameter of first end 12 that said spacer shell 8 is positioned at gooseneck 5 sides is corresponding with molten magnesium alloy leadout hole 16 diameters of gooseneck 5; The through-hole diameter that spacer shell 8 is positioned at second end 13 of penetrating body 2 sides is corresponding with molten magnesium alloy entrance hole 17 diameters of penetrating body 2, and molten magnesium alloy leadout hole 16 diameters of said gooseneck 5 are greater than molten magnesium alloy entrance hole 17 diameters of penetrating body 2.
For guarantee spacer shell 8 and gooseneck 5 and penetrate body 2 contact tight also fixed, also to gooseneck 5 and penetrate body 2 and improve with the end face that spacer shell 8 contacts.End at the molten magnesium alloy leadout hole 16 of gooseneck 5 is provided with first heavy stand 10; Said first heavy stand 10 matches with first end 12 of spacer shell 8; Be provided with second heavy stand 11 at said molten magnesium alloy entrance hole 17 head ends of penetrating body 2, said second heavy stand 11 matches with second end 13 of spacer shell 8.Above-mentioned first heavy stand 10 and second heavy stand 11 are set can effectively be positioned spacer shell 8, and the perforate of its first end 12 closely is connected with leadout hole 16, and the perforate of its second end 13 closely is connected with entrance hole 17, reduces the possibility that molten magnesium alloy solution overflows.
Because the present invention has adopted spacer shell 8; And the through hole 9 two ends opening diameters of spacer shell 8 respectively with the diameter of the leadout hole 16 of gooseneck 5, penetrate body 2 the diameter of entrance hole 17 corresponding; Make that molten magnesium alloy can be from flow through the smoothly through hole 9 of spacer shell 8 of leadout hole 16; Get into the entrance hole 17 of penetrating body 2 again; And can not take place molten magnesium alloy in the prior art can spread all over the end face of penetrating body 2 and with the situation of the horn mouth 14 inner contact positions of gooseneck 5, avoided the generation of molten magnesium alloy spillover effectively.
Simultaneously; Through heating in medium frequency pipe 6 being set in gooseneck 5 peripheries; Penetrate body 2 peripheries resistance wire is set, 2 heating of correlation body, the thermal deformation amplitude that body 2 is penetrated in control; The heat that adds that makes that the resistance wire of penetrating body 2 obtains adds heat greater than gooseneck 5 from what intermediate frequency heating tube 6 obtained, has avoided molten magnesium alloy to overflow from gaping of joints.
