Describes the development of mold manufacturing processes in technology

With the demand of production, few branch industries of metal processing can be as dynamic as die manufacturing. Therefore, it is essential for any die factory to constantly seek the latest technology and innovative ideas. This paper introduces some technological advances that are conducive to creating opportunities or providing a leading position for die and mould processing.

Firstly, the core and cavity of the die are combined to form a part which is processed in parallel on a multi-task machine tool. With flexible inclined milling spindle (b axis) and reverse turning spindle (c axis), the cooling holes on four sides and back of rectangular workpiece are finished by milling. Core and cavity parts are processed while the workpiece is still integrated. By coordinating the rotation of the turning spindle with the tilt of the milling spindle, the surface roughness and tool life can be improved by optimizing the orientation of the tool. The workpiece can also be reversed periodically to facilitate chip dumping.

Then the core and cavity are separated, and each part is still firmly clamped on the reverse turning spindle. Planar milling is carried out for two parts with two new sides exposed respectively, while cooling holes on the two parts of the die are drilled out in one clamp. Compared with traditional processing, this method greatly reduces the clamping times and procedures. Because the two parts of the die keep excellent orientation to each other until they are separated, the accuracy is also improved.

Secondly, the ability of five-axis gun drilling to drill pipelines with composite angles makes it possible to improve the cooling performance of large-scale dies. Five-axis gun drilling machine tools can achieve good economy by eliminating many complex clamps. Dies for automobile bumpers, dashboards and other plastic parts rely on rapid and effective cooling to achieve competitive production cycles. These solutions are not very attractive, and they can not even meet the customer's demand to reduce the price of the mould.

Mold manufacturing and processing technology: The machine features a programmable rotary table and a CNC spindle head 25 degrees more than the lower limit of normal rotation range and 15 degrees more than the upper limit. The machine can be equipped with traditional gun drills, STS (single tube system) type drills, or both. When drilling deep holes with the latter type of bit with a diameter of 1 inch, the speed is as high as 9 inches per minute. The process control system of the machine tool can display the oil pressure, flow rate, feed resistance and torque in a graphical way in real time. This means that the optimal drilling speed can be monitored and the risk of tool failure can be reduced. The machine is designed to be rigid and capable of high-speed milling, drilling and tapping. It needs to be equipped with a tool changer.
