Problems solved by technology

[0002] Most of the die-casting molds pour the molten juice into the mold cavity to die-cast the shape of the product, or pour it into the die-casting port of the mold and squeeze it into the mold cavity. Directly pouring the juice into the mold cavity for die-casting will produce a lot of burrs. It is mainly caused by the inability to control the amount of poured juice, and the method of hydraulically casting juice into the mold cavity is mostly to die-cast through the runner. This die-casting method needs to increase the gate so that the molten juice can quickly enter The mold cavity, but it is difficult to separate the product from the solidified metal of the runner, and needs to be cut and polished. This method results in a long time for product repair

Abstract

The invention discloses a die-casting mold, which comprises a master template, a female mold groove, a liquid outlet hole and a liquid inlet hole are arranged in the female mold template, a female mold is arranged in the female mold groove, and a female mold is arranged on the female mold There are cooling liquid inlet holes and cooling liquid outlet holes, the cooling liquid inlet holes and cooling liquid outlet holes are respectively connected with the liquid outlet holes and the liquid inlet holes, and the master mold is provided with several product forming mechanisms. One side of the product molding mechanism is provided with a positioning demoulding hole, and a tailing material separation mechanism is arranged in the positioning demoulding hole, and the working end of the tailing material separation mechanism cooperates with the product forming mechanism; a die-casting mold of the present invention, through The injection ring injects the molten juice into the molding cavity. At the same time, the injection speed is increased by setting multiple injection holes. By controlling the direction of the large-angle side of the conical cavity, the material in the multiple conical cavities will not be separated. The effect of interference occurs, so that the tailings are quickly detached.

Description

technical field [0001] The invention belongs to the field of die-casting equipment, and in particular relates to a die-casting mold. Background technique [0002] Most of the die-casting molds pour the molten juice into the mold cavity to die-cast the shape of the product, or pour it into the die-casting port of the mold and squeeze it into the mold cavity. Directly pouring the juice into the mold cavity for die-casting will produce a lot of burrs. It is mainly caused by the inability to control the amount of poured juice, and the method of hydraulically casting juice into the mold cavity is mostly to die-cast through the runner. This die-casting method needs to increase the gate so that the molten juice can quickly enter The mold cavity, but it is difficult to separate the product from the solidified metal of the runner, and needs to be cut and polished. This method takes a long time to repair the product. Contents of the invention [0003] The technical problem to be so...
