Die-casting die of horizontal cold chamber die-casting machine and process thereof

Abstract

The invention discloses a die-casting die of a horizontal cold chamber die-casting machine. The die comprises a movable die and a fixed die, wherein the movable die is arranged on the left side of thefixed die, a cavity is formed in the outer wall of the right side of the movable die, the outer wall of the right side of the fixed die communicates with a pouring pipeline, and the pouring pipelinecomprises an inner pipe communicating with the outer wall of the right side of the fixed die; the outer wall of the inner pipe is sleeved with an outer pipe, supporting rods are evenly arranged between the outer wall of the inner pipe and the inner wall of the outer pipe, a filling pipeline in the device is composed of the outer pipe and the inner pipe, a cavity is formed by separating the supporting rods to have an heat insulation effect, and the temperature drop amplitude of a metal liquid raw material added into the filling pipeline is reduced, so that the metal liquid raw material in the pouring pipeline is prevented from being cooled rapidly, and the use performance of the die-casting die is improved. The temperature in the pouring pipeline cannot be too low through an heat insulationlayer and a heating piece, and the probability that the metal liquid raw material is cooled in the pouring pipeline is further reduced.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a die-casting die for a horizontal cold chamber die-casting machine and a process thereof. Background technique [0002] The die-casting mold is an important component of the die-casting machine. When the die-casting mold of the existing horizontal cold chamber die-casting machine is in use, the liquid metal raw material in the holding furnace is added to the pouring pipe of the die-casting mold, and the liquid metal raw material is poured by the die-casting machine. It is input into the cavity of the die-casting mold to produce the product. However, the holding furnace of the horizontal cold chamber die-casting machine is separated from the pressure chamber, which leads to the fact that the metal liquid raw material is completely in the outside during the process of adding the metal liquid raw material, resulting in the loss of the metal liquid raw material. The temperature drops...

[0002] The die-casting mold is an important component of the die-casting machine. When the die-casting mold of the existing horizontal cold chamber die-casting machine is in use, the liquid metal raw material in the holding furnace is added to the pouring pipe of the die-casting mold, and the liquid metal raw material is poured by the die-casting machine. It is input into the cavity of the die-casting mold to produce the product. However, the holding furnace of the horizontal cold chamber die-casting machine is separated from the pressure chamber, which leads to the fact that the metal liquid raw material is completely in the outside during the process of adding the metal liquid raw material, resulting in the loss of the metal liquid raw material. The temperature drops, and the pouring pipe of the die-casting mold is generally just a steel pipe. Because the steel material has a certain thermal conductivity, the metal liquid raw material added to the pouring pipe from the outside is easy to cool down, resulting in the cooling of the metal liquid raw material, and When the die-casting mold starts to be used, the temperature of the metal pouring pipe is low, which will easily lead to the cooling of the metal liquid raw material added from the outside to the inside of the pouring pipe, which will affect the performance of the die-casting mold. Therefore, we propose a horizontal cold chamber die-casting machine Die-casting mold and its process
