Abstract
The pouring gate structure with cycloid shape for die casting molding, comprise the pouring gate structure body with branched form, on the opposite of branched form, to the bridge joint running channel that a cycloid shape is set between branched form, some running channels that enter are set in running channel periphery, the opposite of branched form.It is described that to enter running channel be rectilinear form.The molded line of cast gate of the present utility model is that Second Order Continuous is smooth, and changeover portion adopts cycloid to connect, and can realize melt forward and can arrive at filling end with prestissimo, reaches good die casting effect.Meanwhile, the design of cycloid and machining are all more convenient.
Description
[technical field]
The utility model belongs to the shaping processing technique field of metallic element, specifically refers to a kind of pouring gate structure with cycloid shape of the ADC6 of being applicable to aluminum alloy die-casting die.
[background technology]
ADC6 is the aluminium alloy of the Japanese trade mark, suitable with China GB aluminium alloy ZL303 performance, and its magnesium elements composition accounts for 4%, higher with conventional aluminium alloy phase ratio content.Utilize this manufacture of materials diecast parts, the advantage of part is: (1) institutional framework is fine and close, can be used for carrying class part and alternate load occasion; (2) meet high strength and lightweight requirements; (3) corrosion resistance and good.Its weak point is: (1) magnesium element content is high, and material flowability can be poor, difficult forming thin-walled, limits its light-weighted scope; (2) there is stronger red brittleness; (3) diecasting alloys smelting technology and moulding process all need to redesign or improve, and Design of Dies difficulty is also larger.
In this case, at the parts such as piston rod of motorcycle pedal, engine cylinder of motorcycle, minitype motivation machinery, all select this material.In automobile and motorcycle accessory, the requirement due to functions such as connection, installation or carryings, has the common ADC6 aluminum alloy die casting of a class, and it is tabular that its feature is self, has peninsular structure, has dividing of the He Wai peninsula, the interior peninsula.Peninsular structure increases die casting flow channel length greatly, adds the poor mobile performance of ADC6 aluminium alloy self, realize filling full, is that difficulty all increases greatly on technique or mould.And the design of the pouring gate structure of mould is also the focus of industry thinking.
In view of this, the inventor, for the defect further investigation of prior art, has this case to produce then.
[summary of the invention]
The technical problems to be solved in the utility model, be to provide a kind of pouring gate structure with cycloid shape of the ADC6 of being applicable to aluminum alloy die-casting die, this structure changes conventional linear pattern runner as pseudo-tangent line type curve into, utilize the Second Order Continuous character of matched curve, reduce the flowing pressure attenuation of ADC6, make die casting forward arrive at smoothly thin-walled place, substantially eliminate impact flow, realize steadily and filling.
The utility model is achieved in that
The pouring gate structure with cycloid shape for die cast, comprise the pouring gate structure body with branched form, on the opposite of branched form, to the bridge joint running channel that a cycloid shape is set between branched form, some running channels that enter are set in running channel periphery, the opposite of branched form.
Further, described in, entering running channel is rectilinear form.
The utility model has the advantage of: fully take into account the feature of ADC6 material, the molded line of the cast gate of design is smooth, changeover portion adopts cycloid to connect, and can realize melt forward and can arrive at filling end with prestissimo, reaches good die casting effect.Meanwhile, the design of cycloid and machining are all more convenient.
[accompanying drawing explanation]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the aluminum alloy part structural representation of the utility model peninsula thin-wall construction.
Fig. 2 is pouring gate structure schematic diagram of the present utility model.
[specific embodiment]
As shown in Figure 1, ADC6 aluminum alloy spare part with peninsula thin-wall construction, comprise die ontology 1, apparatus derivatorius 2, the design of its pouring gate structure, as shown in Figure 2, comprise the pouring gate structure body 10 with branched form 20, on the opposite 30 of branched form 20, to the bridge joint running channel 40 that a cycloid shape is set between branched form 20, some running channels 50 that enter are set in the 30 running channel peripheries, opposite of branched form 20.Enter running channel 50 for rectilinear form.
The utility model fully takes into account the feature of ADC6 material, and the molded line of the cast gate of design is that Second Order Continuous is smooth, and changeover portion adopts cycloid to connect, and can realize melt forward and can arrive at filling end with prestissimo, reaches good die casting effect.Meanwhile, the design of cycloid and machining are all more convenient.This configuration flexibility is large, can reach the effect that significantly reduces the die casting pressure loss, meets the die-cast product feature that shape is changeable.
The foregoing is only better enforcement use-case of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any modification of doing, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. for the pouring gate structure with cycloid shape of die cast, it is characterized in that: comprise the pouring gate structure body with branched form, on the opposite of branched form, to the bridge joint running channel that a cycloid shape is set between branched form, some running channels that enter are set in running channel periphery, the opposite of branched form.
2. the pouring gate structure with cycloid shape for die cast as claimed in claim 1, is characterized in that: described in to enter running channel be rectilinear form.
