Description
Technical field
This utility model relates to die casting machine particular manufacturing craft field, is specifically related to a kind of backrest mould.
Background technology
Die casting is a kind of metal casting technique, is characterized in utilizing the mold cavity metal to melting to apply high pressure.Mould typically processes with the higher alloy of intensity, some the similar injection mo(u)lding of this process.According to the difference of die casting type, cold chamber die casting and hot chamber diecasting can be divided into.Cold chamber die casting can be used, including the kirsite that aluminum, magnesium, copper and aluminum content are higher when die casting being not used to the metal of hot chamber diecasting technique.In such a process, need first metal molten to be fallen in an independent crucible.The most a number of motlten metal is transferred in an injection room the most heated or injection nozzle.By hydraulic pressure or mechanical pressure, these metals are injected among mould.Owing to needs are transferred into cold house motlten metal, the shortcoming of this technique maximum is that circulation time is the longest.And die casting is a requisite part in die-casting system, its main purpose is so that in metallic solution energy mould inside die cavity formation die casting machine, but during metallic solution injection enters die cavity, too fast and too early press-in die cavity always makes the air of mold cavity cannot discharge too much, in turn result in die casting and there is pore, the defects such as shrinkage cavity, for the backrest of seat, attractive in appearance for structure, multiple curve is generally used to be mutually combined the backrest forming different-style, and structure is hollow out state, thus the firmness of backrest and stability are always the problem that producer needs to solve.
Utility model content
In view of the above, the purpose of this utility model is to provide a kind of backrest mould, by the optimization of himself structure while guaranteeing that structure is attractive in appearance, strengthen the stability of backrest, reduce die casting and produce pore, the probability of shrinkage cavity.
A kind of backrest mould, it is characterized in that, including die holder, described die holder corner is respectively arranged with the locating piece of projection, described die holder both sides are respectively arranged with hole, location, described die holder front is provided with sprue, described sprue both sides are respectively arranged with overflow launder, two overflow launders are also respectively provided with secondary channels away from side, sprue direction, described sprue is connected with the holding groove of genesis analysis respectively with secondary channels, wherein, oval die cavity it is provided with on described die holder centre position, multilamellar ellipse runner it is provided with outside it, described oval runner both sides are connected to half round runner, the side frame die cavity of cross direction profiles it is provided with between described half round runner two ends, and it is arranged above running through the ornamental strip of whole die holder at oval runner and half round runner.
A kind of backrest mould that this utility model provides can be further arranged between described multilamellar ellipse runner be additionally provided with the through runner in lateral arrangement.
A kind of backrest mould that this utility model provides can be further arranged to outside described sprue be additionally provided with injection mouth, and the cross section of injection mouth is round platform cross section.
A kind of backrest mould that this utility model provides can be further arranged to described overflow launder and taper into the direction collecting volume away from sprue from sprue.
Of the present utility model preferential and have the beneficial effect that
1, sprue and the cooperation of secondary channels so that molten metal can enter die holder inner chamber body the most slowly, when the molten metal injected is too much, can show and play certain cushioning effect by overflow launder；
2, hole, location and the setting in hole, location, it is ensured that die holder can accurately dock, it is ensured that die holder stability during injection molten metal；
3, the ornamental strip of through die holder makes the molten metal containing gas or material slag can be discharged by ornamental strip both side ends, prevents the generation of defect ware.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings preferred implementation of the present utility model is the most preferably described, wherein,
A kind of backrest mould schematic diagram that Fig. 1 provides for this utility model.
Detailed description of the invention
With reference to Fig. 1, this utility model one backrest Die Embodiment is described further.
