Abstract
The invention discloses a die-casting die of the radiator of a projector, and aims to provide a die-casting die with good venting performance for manufacturing a radiator with less pores and high heat dissipation efficiency. The die is provided with a material handle which is communicated with the die opening of the die; the material handle is communicated with a sprue in the die; the sprue is communicated with a cross gate; the cross gate is communicated with an ingate; the ingate is communicated with the die opening; in the die opening of the die of the radiator, an air discharge duct is arranged between the die openings of the corresponding radiating fins of the radiator; in the flask joint of the die, an air discharge block for centralized air discharge is arranged. The radiator manufactured by the die has good heat dissipation efficiency and is applicable to the manufacture field of radiators of projectors.
Description
Technical field
The present invention relates to a kind of die casting, more particularly, relate to a kind of die casting of making the radiator of projecting apparatus.
Background technology
In the prior art, projecting apparatus needs to rely on radiator to dispel the heat in operate as normal, if the radiating effect of radiator is bad, can cause projecting apparatus because of overheated and then influence service life of whole instrument, and radiating effect directly translates into the radiating efficiency of radiator, thereby the height of the radiating efficiency of radiator directly influences service life of projecting apparatus in the projecting apparatus, in the use of reality, the quantity of pore will directly influence the efficient of heat radiation in the radiator, if pore is many, then radiating efficiency is low, pore is few, radiating efficiency height then, thereby, in the production process of radiator, the quantity of pore in the control radiator, become the key factor that improves radiator heat-dissipation efficient, in the extrusion process of prior art, because the wall thickness variation of each part is bigger in the radiator, the thickness reaches 10 millimeters, thinnest part has 2 millimeters, thereby difficult forming, and pore is many; Therefore the mode of most use aluminium extruded type of radiator is produced before, but the back operation processing that the mode of aluminium extruded type is produced is many, the cost height, thereby, in the art, be badly in need of providing a kind of and can better control the die casting that pore produces in the radiator.
Summary of the invention
Technical purpose of the present invention provides a kind of well exhaust in the die casting production process, and it is few to produce pore, has the die casting of the radiator of good heat radiating efficient.
For realizing above technical purpose, technical scheme of the present invention is: a kind of die casting of protector radiator, this mould is provided with the material handle that is communicated with the die cavity of described mould, and described material handle is communicated with the sprue in the mould, and sprue is communicated with cross gate, cross gate is communicated with ingate, ingate is communicated with die cavity, in the die cavity of described radiator mould, is provided with air discharge duct between the die cavity of corresponding radiator fin, at the die joint of described mould, be provided with the exhaust piece of concentrating exhaust.
In the present invention, adopted the principle of extrusion casint, big flow when adopting the molten metal casting, low speed, the principle of high pressure designs; Whole running gate system is closed, and this design has reduced the volume gas that molten metal produces as much as possible in casting cycle, part can be satisfied solidify simultaneously and make that the residual gas disperse distributes in the aluminium liquid.The mobile direction of molten metal is to be full of whole die cavity by the injection from bottom to top of material handle, sprue, cross gate, ingate, and the cross section ratio of above-mentioned material passage is 5: 3: 1.3: 1; And, between every fin die cavity, all have the air discharge duct of 0.2mm, making the exhaust smoothly of the dark chamber of mould, described material handle when producing is a hollow pipeline formula structure.
The invention has the beneficial effects as follows, exhaust piece by being arranged on the mould die joint and be arranged on air discharge duct in the fin, when carrying out die casting, above-mentioned exhaust piece and air discharge duct can in time be discharged the gas in the mould cavity admirably, greatly reduced gas residual in the molten metal, can control pore quantity in the radiator that die casting comes out well, make the radiator heat-dissipation efficient height of producing, good heat dissipation effect.
Description of drawings
Accompanying drawing is the structural representation of die casting in the one embodiment of the invention.
The specific embodiment
Present embodiment is the preferred embodiment of the present invention, and all its principles and basic structure are identical with the present invention, all belong within protection scope of the present invention.
As shown in the figure, in the present invention, be provided with the material handle 1 that is communicated with described mould cavity, the sprue 2 that described material handle 1 is communicated with in the mould, sprue 2 is communicated with cross gate 3, cross gate 3 is communicated with ingate 4, ingate 4 is communicated with the die cavity 7 of mould, in the die cavity 7 of described radiator mould, between the die cavity of corresponding radiator fin, be provided with air discharge duct 5, air discharge duct 5 has been communicated with the die cavity 7 and the mould external space, at the die joint of described mould, is provided with the connection cavity body of mould and can concentrates the exhaust piece 6 of exhaust.
Whole casting mold is closed, adopts this design to reduce the volume gas that molten metal produces as much as possible in casting cycle, part can be satisfied solidify simultaneously and make that the residual gas disperse distributes in the aluminium liquid.The mobile direction of molten metal is to be full of whole die cavity by the injection from bottom to top of material handle, sprue, cross gate, ingate, and the cross section ratio of above-mentioned material passage is 5: 3: 1.3: 1; And, between every fin die cavity, all have the air discharge duct of 0.2mm, when producing, make the exhaust smoothly of the dark chamber of mould.
In press casting procedure, high-pressure metal liquid enters sprue 2 by material handle 1, pass through cross gate 3 again, cross gate 3 is communicated with ingate 4, molten metal enters die cavity 7 through ingate 4, in the die cavity 7 of described radiator mould, the residual gas that produces is then by the air discharge duct 5 between the die cavity 7 of corresponding radiator fin, and discharges at the exhaust piece 6 of the concentrated exhaust of the die joint of described mould.
In this preferred embodiment, exhaust piece 6 and air discharge duct 5 also can be communicated with a small-sized air exhauster respectively, in press casting procedure, because the effect of air exhauster, make whole die cavity be a suction type state, thereby the residue gas physical efficiency that may exist in molten metal and the die cavity is discharged better, because the gas in the die cavity is drawn out of, and then the pore that can control product better produces.
In a word, the present invention is by the appropriate design of die cavity, and by exhaust piece and air discharge duct are set, the technical scheme that can better the gas in the mould cavity in time be discharged in press casting procedure makes the radiator heat-dissipation efficient height of producing, good heat dissipation effect.
