Abstract

The invention relates to a die-casting die and a die-casting method of a product, the die-casting die comprises a first die holder, a second die holder and an extrusion assembly, the second die holder is matched with the first die holder, when the first die holder and the second die holder are closed, a cavity is formed between the first die holder and the second die holder, and the cavity is used for injecting molten first metal liquid; an auxiliary cavity communicating with the cavity is further formed in the side, facing the second mold base, of the first mold base, corresponds to the position of a to-be-repaired part of the product blank and is used for containing molten second metal liquid; and the extrusion assembly is used for penetrating through the first die holder and stretching into the auxiliary cavity so as to extrude the semi-molten second metal liquid into the cavity, so that the semi-molten second metal liquid and the semi-molten first metal liquid are fused into a whole. And sand holes are formed in the product due to inconsistent cooling molding shrinkage of some parts of the product.

Description

technical field [0001] The invention relates to the technical field of die-casting, in particular to a die-casting mold and a die-casting method for a product. Background technique [0002] The cold chamber die-casting machine pours the molten metal liquid into the injection chamber (injection barrel) by means of a spoon, and then uses the injection piston (hammer head) to push the metal liquid into the mold at high speed. A casting equipment that is cooled and solidified to obtain a finished product. However, when molding products with uneven wall thickness, some parts of the product are prone to sand holes inside the product due to inconsistent cooling and molding shrinkage, which makes it difficult to ensure the density of the product and affect the yield of the product. Contents of the invention [0003] Based on this, the present invention provides a die-casting mold and a die-casting method for a product that can effectively solve the problem of sand holes inside th...
