Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of inlaying and splicing contour cooling structures, specifically to a kind of inlaying and splicing contour cooling structures of circular deep cavity die casting die. BACKGROUND

[0002] Fig. 1 and Figure 2 The moving die deep cavity core has high quality requirements, and the area also needs to arrange ejector rods. The existing ordinary point cooling 1' cannot achieve ideal cooling effect, which easily leads to serious sintering. The conventional 3D printed whole insert 2' is more easily damaged due to large thermal stress changes in the head shape, and its service life cannot achieve ideal effect. If damaged, it needs to be replaced as a whole, which leads to an increase in use cost. SUMMARY

[0003] To solve the problems of poor cooling effect and inconvenient replacement of whole inserts, the utility model provides an inlaying and splicing contour cooling structure of circular deep cavity die casting die, which improves the cooling efficiency of products and improves product quality.

[0004] The utility model provides the following technical scheme:

[0005] An inlaying and splicing contour cooling structure of circular deep cavity die casting die includes a head insert, a bottom insert, an ejector rod, a contour water tank, a water pan, a cooling hard tube, and a point cooler. The ejector rod is inserted into the bottom insert and passes through the head insert. The contour water tank is arranged inside the head insert for cooling. The water pan is below the contour water tank. The cooling hard tube is inserted into the bottom insert and passes through the water pan. The bottom insert is provided with a point cooling hole. The point cooler is inserted into the point cooling hole. The point cooler is provided with a plug at the top. The water pan and the head insert are welded to form a whole. The water pan and the bottom insert are combined and connected.

[0006] Further, the water pan is provided with a water inlet and a water outlet. Two cooling hard tubes are inserted into the water inlet and the water outlet of the water pan, respectively.

[0007] Further, the water pan and the bottom insert are connected by fastening bolts to form a whole.

[0008] Further, the head insert is provided with a reserved welding process pit.

[0009] Compared with the prior art, the head shape thermal stress changes greatly, and the original whole insert is changed into an insert assembly, which is composed of a head insert and a bottom insert, the head insert assembly is designed to be profiled cooling, and the bottom insert is point cooled.

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Please refer to Figures 3-6 The utility model discloses a kind of insert profiled cooling structures of circular deep cavity die casting mould, including head insert 1, bottom insert 3, ejector rod 4, profiled water tank 6, water pan 2, cooling hard pipe 11 and point cooler 10, ejector rod 4 is inserted into bottom insert 3 and passes through head insert 1.

[0019] ​The two inserts are designed as spliced ​​inserts. A contoured water tank 6 is provided inside the head insert 1 for cooling. Below the contoured water tank 6 is a water isolation tray 2, which plays the role of adjusting the cooling direction and sealing.

[0020] The water-isolating plate 2 and the head insert 1 are integrated by welding.

[0021] A water inlet 21 and a water outlet 22 are provided in the water-isolating tray 2, and a cooling hard pipe 11 is inserted into the bottom insert 3 and passes into the water-isolating tray 2. The two cooling hard pipes 11 are respectively inserted into the water inlet 21 and the water outlet 22 of the water-isolating tray 2 to form a cooling circuit.

[0022] A cooling hole 9 is opened in the bottom insert 3, a cooling device 10 is inserted into the cooling hole 9, and a plug 8 is installed on the top of the cooling device 10 to ensure that the entire component is fully cooled.

[0023] The head insert 1 is combined with the water barrier 2 and then welded together to form a whole. After the sealing test and stress relief tempering, the water barrier 2 and the bottom insert 3 are combined and fastened together as a whole by fastening bolts 5 ( Figure 6 shown).

[0024] A welding process pit 7 is reserved on the head insert 1 to improve the overall connection strength.

[0025] Because the head shape is subject to significant thermal stress changes and is more susceptible to damage, the present invention replaces the original integral insert with a spliced ​​design, consisting of two major components: the head insert and the bottom insert. This reduces maintenance costs by replacing only the head insert, not the entire component. The head insert is equipped with a contoured water tank, while the bottom insert utilizes a spot cooler 10. This design offers better cooling than the original structure, more uniform cooling, a longer service life than 3D-printed integral inserts, and enhanced maintenance for ongoing production.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
