Further, slide block is two, is separately positioned on two ends of dynamic model.

Further, slide block is by hydraulic oil cylinder driving.

Further, also be provided with ejecting mechanism on the dynamic model, it is used for ejecting product.

Compared with prior art, the utlity model has following advantages: the utility model provides a kind of die casting, cover half mold insert and the dynamic model mold insert of this die casting are made by the beallon material, the beallon material has high strength, high thermal conductivity, and wear-resisting, corrosion-resistant, use cover half mold insert and the dynamic model mold insert thermal diffusivity of this kind material very good, thereby in the process of converted products, so that the molding cycle of product is short, and then greatly improved operating efficiency, reduced production cost, be with a wide range of applications.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby more removes clear and definite defining so that advantage of the present utility model and feature are easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model made.

Consult Fig. 1 to Fig. 3, Fig. 1 is the top view of die casting of the present utility model, and Fig. 2, Fig. 3 are respectively the upward view of cover half of this die casting and the top view of dynamic model.As can be seen from the figure, the cover half 1 that is used for linking to each other with the compression section of die casting machine is provided with the cover half die cavity, dynamic model 2 is arranged on the below of cover half 1 movably, in general, dynamic model 2 can be fixed in the die casting machine on the plate, move with plate in the die casting machine, dynamic model 2 is provided with the dynamic model die cavity, and the cover half die cavity matches with the dynamic model die cavity and forms the die cavity of mould.Cover half 1 is provided with the cover half mold insert 11 of being made by the beallon material, it is fixed by the cover half cage plate, also be provided with the dynamic model mold insert 21 of also being made by the beallon material on the dynamic model 2, it is fixed by the dynamic model cage plate, cover half mold insert 11 matches with dynamic model mold insert 21 during matched moulds, because the beallon material has the premium properties such as high strength and high heat conduction, thereby in the production process of product, mold insert has improved good heat radiation function, can greatly shorten the molding cycle of product, the molding cycle of the product of traditional die casting is approximately 90 seconds, and the formed product cycle of die casting of the present utility model can shorten to about 53 seconds, that is, die casting of the present utility model can shorten the molding time of single product about 37 seconds in the process of shaping finished product, like this, operating efficiency improves greatly, and output has had significantly lifting, but the demand that day by day improves of satisfying the market, simultaneously also reduce widely cost, saved fund.3, two slide blocks 3 of two slide blocks that also are fixed with oil cylinder 4 on the dynamic model 2 and are slidably disposed on the dynamic model 2 are separately positioned on two ends of dynamic model 2, and slide block 3 can take out product with convenience in the driving lower slider of oil cylinder 4.Also be provided with the ejecting mechanism 5 for ejecting product on the dynamic model 2, after the formed product, away from product, Free up Memory is so that ejecting mechanism 5 ejecting products under the drive of oil cylinder 4 for slide block 3.
