Embodiment Construction

[0017] Such as Figure 1-Figure 4 As shown, including the mold 1, there are several oil ports 2 on the left and right sides of the mold 1, and two of the oil ports on each side communicate through the pipeline embedded in the mold 1 and form a set of oil guide passages , one of the oil ports is used as the inlet, and the corresponding other oil port is used as the outlet.

[0018] Such as figure 1 As shown, in the first embodiment, every three sets of oil guide passages are connected in series through the oil pipes 3 installed externally on the corresponding oil ports and connected to a mold temperature controller to form an oil circuit cycle. According to the key points in casting molding The area is divided into several temperature control zones at the corresponding positions of the mold 1, and each temperature control zone is formed by the covering part of each oil circuit circulation in the mold body. According to the shape characteristics of the casting, the mold 1 in E...

Abstract

The invention relates to a temperature control method for a magnesium alloy pressure casing die. A plurality of temperature control areas are divided according to a corresponding position of a critical area during casting forming in the die and temperature of every temperature control area is controlled through a die temperature controller to provide temperature constant oil to heat when encounters cold and to cool when encounters heat. According to the temperature control method for the magnesium alloy pressure casing die, the plurality of temperature control areas are divided in the critical area of the die; the temperature of the temperature control areas are controlled through the temperature constant oil provided through the die temperature controller; when a casting deforms, cooling shrinkage of the casting is controlled through adjustment of the temperature differences of the temperature control areas, deformation of the casting is reduced, and the casting quality of the casting is guaranteed; meanwhile compared with the traditional technology which cools through water and heats through oil, a flexible control purpose is achieved due to the fact that the temperature constant oil heats the die when encounters cold and cools the die when encounters heat. The temperature control method for the magnesium alloy pressure casing die is applied to casting of magnesium alloy vehicle door pressure castings.

Description

technical field [0001] The invention relates to a temperature control method of a die-casting mold, in particular to a temperature control method of a magnesium alloy die-casting mold. Background technique [0002] At present, the vast majority of car door frames are sheet metal parts formed by stamping, which has disadvantages such as difficult manufacturing, many processes, and complicated processes. Therefore, technicians at home and abroad hope to use magnesium alloy die-casting manufacturing methods to produce aluminum alloys. Door frame. Magnesium alloy door frame die-casting is an extra-large thin-walled part. The door frame has a large external dimension, the wall thickness is only 2mm, and the weight of a single casting is less than 3kg. It is an extra-large automotive die-casting thin-walled part. Due to the use of magnesium alloy material, magnesium liquid is easier to oxidize than aluminum liquid, and the mold is huge, and the mold temperature has a great influe...
