Abstract
The utility model discloses plate die casting in a kind of mobile phone aluminium and comprises front mould and rear mold, die cavity is formed between described front mould and described rear mold, described die cavity comprises feed channel, middle sheet metal forming chamber and dreg discharging tunnel, described feed channel and dreg discharging tunnel lay respectively at the two long limits in described middle sheet metal forming chamber, the depth bounds of described feed channel near described middle sheet metal forming chamber place is 1.0 to 1.5mm, and the depth bounds of described dreg discharging tunnel near described middle sheet metal forming chamber place is 1.0 to 1.2mm.In the utility model mobile phone aluminium, plate die casting can use pure aluminum material to be cast into plate in mobile phone aluminium, and yields is high.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to plate die casting in a kind of mobile phone aluminium.
Background technology
Along with the development of mechanics of communication, popularizing of smart mobile phone is more and more wider, and demand significantly improves.Smart mobile phone is generally made up of screen, mainboard, handset mounting and battery, and the middle plate on handset mounting typically uses, and aluminum alloy materials die casting makes, this is because aluminum alloy materials is very good by the flowing of mold cavity in the molten state, therefore, in die casting aluminium alloy out, plate yields is high.
But because aluminium alloy contains the element such as carbon, silicon, therefore, in above-mentioned aluminium alloy, plate can not carry out surface oxidation, this needs to be oxidized to plate in the mobile phone of various color for side, uses aluminum alloy materials to become a large problem of oxidation technology.Obviously, be oxidized by using the fine aluminium of not carbon containing, element silicon, effect can be better, but, because the mobility of fine aluminium is poor, and the charging degree of depth of existing mold cavity is 0.5 to 0.7mm, the discharge degree of depth is 0.5 to 0.6mm, uses existing die casting to become plate in aluminium, easily in mould, produces bubble, make the surface of product more coarse, fraction defective is higher.For above-mentioned contradiction, up to the present, prior art can't solve well.
Utility model content
The purpose of this utility model is to provide one that pure aluminum material can be used to be cast into plate in mobile phone aluminium, and plate die casting in the high mobile phone aluminium of yields.
To achieve these goals, in the mobile phone aluminium that the utility model provides, plate die casting comprises front mould and rear mold, die cavity is formed between described front mould and described rear mold, described die cavity comprises feed channel, middle sheet metal forming chamber and dreg discharging tunnel, described feed channel and dreg discharging tunnel lay respectively at the two long limits in described middle sheet metal forming chamber, the depth bounds of described feed channel near described middle sheet metal forming chamber place is 1.0 to 1.5mm, and the depth bounds of described dreg discharging tunnel near described middle sheet metal forming chamber place is 1.0 to 1.2mm.
Compared with prior art, because the utility model is by laying respectively at the two long limits in described middle sheet metal forming chamber by described feed channel and dreg discharging tunnel, and the depth bounds of described feed channel near described middle sheet metal forming chamber place is set to 1.0 to 1.5mm, the depth bounds of described dreg discharging tunnel near described middle sheet metal forming chamber place is set to 1.0 to 1.2mm, thus effectively improve the mobility of aluminium in mould of melting, and then reach the object that fine aluminium can be cast into plate in aluminium, by improving the mobility of mould inside, bubble in mould is significantly reduced, the surface smoothing of plate in the aluminium processed, thus improve the yields of plate in aluminium.
Preferably, the width of described feed channel equals the length in described middle sheet metal forming chamber.
Preferably, the quantity of described dreg discharging tunnel is many, is distributed in the length direction in described middle sheet metal forming chamber respectively equably.
Preferably, form two described die cavities between described front mould and described rear mold, the described feed channel of die cavity described in two is communicated with same liquid injection port.
Accompanying drawing explanation
Fig. 1 is the structural representation of plate die casting in the utility model mobile phone aluminium.
Fig. 2 is the structural representation of plate die casting in the utility model mobile phone aluminium.
Fig. 3 is the side view of plate die casting in the utility model mobile phone aluminium.
Detailed description of the invention
For describing technology contents of the present utility model, structural feature, the effect that realizes in detail, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
As shown in Figure 1, Figure 2 and Figure 3, in the utility model mobile phone aluminium, plate die casting 100 comprises rear mold 1 and front mould (not shown), two die cavities 11 are formed between described front mould and described rear mold 1, described in two, die cavity 11 is symmetrical set, described die cavity 11 comprises feed channel 11a, middle sheet metal forming chamber 11b and dreg discharging tunnel 11c, and the described feed channel 11a of die cavity 11 described in two is communicated with same liquid injection port 12.The described feed channel 11a of first described die cavity 11 and dreg discharging tunnel 11c lays respectively at the two long limits of described middle sheet metal forming chamber 11b, the depth bounds of described feed channel 11a near the A place of described middle sheet metal forming chamber 11b is 1.0 to 1.5mm, and the depth bounds of described dreg discharging tunnel 11c near the B place of described middle sheet metal forming chamber 11b is 1.0 to 1.2mm; Therefore in the mobile phone aluminium processed, the thickness L1 corresponding to the clout 201 at the A place of feed channel 11a of plate 200 is also 1.0 to 1.5mm, and the thickness L2 corresponding to the clout 202 at the B place of discharge road 11b is also 1.0 to 1.2mm.Described feed channel 11a arranges one, and its width equals the length of described middle sheet metal forming chamber 11b.The quantity of described dreg discharging tunnel 11c is many, is distributed in the length direction of described middle sheet metal forming chamber 11b respectively equably.
Compared with prior art, because the utility model is by laying respectively at the two long limits of described middle sheet metal forming chamber 11b by described feed channel 11a and dreg discharging tunnel 11c, and the depth bounds of described feed channel 11a near the A place of described middle sheet metal forming chamber 11b is set to 1.0 to 1.5mm, the depth bounds of described dreg discharging tunnel 11c near the B place of described middle sheet metal forming chamber 11b is set to 1.0 to 1.2mm, thus effectively improve the mobility of aluminium in mould of melting, and then reach the object that fine aluminium can be cast into plate in aluminium, by improving the mobility of mould inside, bubble in mould is significantly reduced, the surface smoothing of plate in the aluminium processed, thus improve the yields of plate in aluminium.
Above disclosedly be only preferred embodiments of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
