Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

< example >

fig. 1 is a schematic structural diagram of a mold with a shape following water path cooling structure in an embodiment of the invention.

as shown in fig. 1, in the present embodiment, a mold 100 having a conformal water path cooling structure is used for processing a matched product to be processed. The mold 100 is composed of a plurality of mold pieces 10 having a predetermined thickness, where the predetermined thickness of each mold piece 10 has a value of 20 to 30 mm.

In this embodiment, the number of the dies 10 shown in fig. 1 is three, and the overall shape and size of the three dies 10 are completely the same, and only the positions of the water passages provided therein are different. Each die 10 has two surfaces 11, the two surfaces 11 of the middle die 10 facing the two side dies 10, respectively, one surface 11 of the two side dies 10 facing the adjacent die 10 and the other surface 11 facing outward.

A water flow groove 12 is provided at a predetermined position of the surface 11 of each die 10 based on the shape and size of a corresponding product to be processed for processing by the mold 100; thus, when two adjacent dies 10 are fixed, two corresponding water channels 12 form a water channel 13, and each water channel 13 has a water inlet 14 and a water outlet 15.

The bottom of each water flow channel 12 has a predetermined distance from the bottom of the corresponding product cavity, where the predetermined distance has a value of 10 to 15 mm. Thus, a certain distance is always kept between the waterway channel 13 and the injection product, the cooling water flowing through the waterway channel 13 is close to the surface of the mold, the heat accumulated in the mold is greatly reduced, and the heat is limited in the area between the waterway channel 13 and the surface of the mold, so that the path for conducting heat from the surface of the mold cavity to the waterway channel 13 is also greatly shortened.

In this embodiment, only the inward surfaces 11 of two mold pieces 10 at both ends of the plurality of mold pieces 10 are provided with water flow grooves 12, and the outward surfaces 11 thereof are the outer surfaces of the mold 100 and are kept as smooth surfaces, without providing the water flow grooves 12.

The waterway channel 13 can be designed into a complex shape, wherein the waterway channel 13 is curved, the diameter of the waterway channel 13 can be changed continuously, and the cross section can be any one of a circle, an ellipse or a square according to the cooling requirement. Here, the shape and diameter of each waterway channel 13 are calculated based on a predetermined analysis algorithm, and the cooling manner of the mold can be greatly optimized through calculation and cooling analysis, thereby shortening the mold cycle and improving the quality of parts, especially in the volatile real and deformation regions.

Further, when the plurality of layers of the mold pieces 10 are fixed to form the mold 100, all the water passages 13 formed in the mold 100 can be distributed along with the shape of the product to be processed, so as to form a conformal water passage cooling structure, and the conformal water passage cooling structure has one less water passage 13 than the number of the mold pieces 10. In addition, every two adjacent dies 10 are fixedly connected by diffusion welding.

In addition, the mold 100 has a product cavity for injection molding to form a product to be processed, and the processing step of the product cavity is that after the plurality of layers of mold pieces 10 are fixedly connected, the plurality of layers of mold pieces 10 with the processed shape-following water paths are assembled together, smelting is carried out by using a diffusion welding technology to form a complete square material, and then the product cavity is processed, so that the material of the whole mold 100 is ensured to be unchanged, any material is not required to be added, and the polishing precision of the product injection molded by the mold 100 is ensured.
