Along with the rapid development of the light weight and the integration of the automobile body, a plurality of complex structural parts can be realized by high-pressure casting, and the new structure innovation of the die casting die is imperative. For complex large die casting molds, a good temperature field is a critical condition for producing good quality castings. The unbalance of the temperature field of the die often causes quality problems such as shrinkage cavity, shrinkage porosity and the like of the internal quality of the casting, so that reasonable arrangement of cooling water in a limited space is very important. In the past, the setting mode of the mold cooling water is two kinds of line cooling and high-pressure point cooling, and the line cooling is generally poor because a cooling water channel can only be formed on a mold sliding block, and the length of a flow channel is limited. The high-pressure spot cooling effect is better but is mostly used for core cooling, and the quantity is limited due to space limitation when the high-pressure spot cooling device is used for large-area cooling of complex modules.

Detailed Description

The utility model will be described in further detail with reference to specific embodiments and drawings.

The integrated water-through positioning key for the die-casting mould as shown in fig. 1-2 comprises a positioning key body 1, a water inlet pipe 2, a sealing sleeve 3, a cooling water pipe 4 and a water outlet pipe 5, wherein the positioning key body 1 is subjected to 45-steel thermal refining, two layers of waterways are formed in the positioning key body, one layer of waterways is a water inlet waterway 6, the other layer of waterways is a water return waterway 7, and a waterway side outlet is plugged by a metal plug. The water inlet pipe 2 and the cooling water pipe 4 are respectively connected with the two sides of the positioning key body 1 and are directly communicated with the water inlet waterway 6 inside. The number of the cooling water pipes 4 is multiple, and the cooling water holes can be matched specifically according to the mold slide block to be cooled, and other useless water outlets can be closed by plugs. The cooling water pipes 4 are distributed on the positioning key body 1 at intervals, the cooling water pipes 4 are arranged in parallel, and the cooling water pipes 4 are higher than the end face of the positioning key body 1 by a preset height, so that the cooling water pipes can extend into cooling water holes of the sliding blocks or the inserts on the die.

The outside at condenser tube 4 is established to seal cover 3 cover, and the quantity of seal cover 3 and condenser tube 4's quantity phase-match, and seal cover 3 is provided with a plurality of sealing rings on the seal cover 3 on location key body 1, seal cover 3 lower half passes through sealing ring and location key body 1 sealing connection, and seal cover 3 upper half exceeds the terminal surface reservation height of location key body 1 for connect the cooling water hole on mould or the slider.
