4. All the plates are connected by diffusion welding to form a whole, and the shape of the whole is cuboid, cube, cylinder and other structures. At this time, the welded beryllium copper material part needs to be machined with high precision. The high-precision machining mainly processes the mechanism characteristics required by beryllium copper material parts during design: such as the processing of the shape of the product, such as the ejection structure ejector rod hole, the processing of the injection molding glue inlet flow channel, the peripheral shape of the product and the like. The beryllium copper material die system can be ensured to be capable of producing finished products reasonably.

The parts are prevented from being collided and damaged in the installation process.

The embodiment of the invention provides a beryllium copper material-based mold conformal water channel which is manufactured by adopting a beryllium copper material, and specifically comprises a pipe body 8 arranged in the mold and used for transmitting a heat transfer medium to adjust the temperature of the mold, wherein the pipe body 8 is of a multi-layer pipeline structure, two adjacent layers of pipeline structures are connected in a diffusion welding mode to form a communication structure, one end of the pipe body 8 is provided with a plurality of connecting ports 6 which are respectively communicated with corresponding parts of the pipe body 8 in a diffusion welding mode to realize the inlet and outlet of the heat transfer medium, the connecting ports 6 are communicated with the outside of the mold, the beryllium copper material-based mold conformal water channel manufacturing method is provided, the beryllium copper material-based mold conformal water channel part which is manufactured by adopting a diffusion welding process is designed by using an optimized cooling scheme, compared with brazing or other welding processes, the connecting strength and the service life are better, the cooling efficiency can be optimized, the die can be used for mass production, and the problems that steel is adopted in the conventional die system along with the shape water path and is processed in a conventional machining mode, or beryllium copper is adopted to be processed through the conventional welding process, and the cooling efficiency is not high are solved.
It should be noted that, the main forming parts of the traditional mold system are processed by the cooling waterway flow channel by the traditional machining method, the traditional mold steel material parts can also have a cooling system with good heat dissipation efficiency by using the diffusion welding process, and the beryllium copper material parts cannot be manufactured into the shape following waterway parts with high reliability because the diffusion welding process is not available. The cooling water channel processing can be carried out only by the traditional processing mode, and though the heat conductivity of the beryllium copper material is better than that of the die steel material, the beryllium copper material is not an optimal cooling scheme.
The beryllium copper material mould conformal waterway part manufactured by adopting the diffusion welding process has an optimized cooling scheme, and the design scheme of high heat conductivity of the beryllium copper material and high degree of freedom of the conformal waterway can efficiently take away heat generated in the moulding process of the mould system. The die system does not generate metal fatigue due to high temperature, and has longer service life and higher economic benefit. The beryllium copper material die conformal water channel parts can achieve mechanical properties similar to those of parent metal through a diffusion welding process connection method, and compared with brazing or other welding processes, the beryllium copper material die conformal water channel parts have better connection strength and service life by adopting the diffusion welding process, and meanwhile, the cooling efficiency can also be optimized. Moreover, because the die system is known as an industrial banknote printing machine, the beryllium copper material die conformal waterway part manufactured by adopting the diffusion welding process can be used for mass production, and the efficient cooling efficiency shortens the forming period as much as possible and prolongs the service life. The economic gain is much greater than with conventional die systems.
It should be further noted that the present invention has a significant effect on heat dissipation of the product molded part during the injection molding process. The invention is characterized in that the die steel is used as a forming part material in the traditional die, the beryllium copper material is used in the invention, the heat dissipation effect of the conventional die steel material conformal waterway part is not better than that of the beryllium copper material conformal waterway part, and the beryllium copper material part can also have the conformal waterway by combining the beryllium copper material with a diffusion welding connection process.
