Die component group processing and manufacturing technology

The group processing and manufacturing technology of mold components is developed in the context of solving the above three major problems, mainly for the processing of similar or mirror components of molds (movable punch, press plate, insert) : By simplifying the manufacturing process of similar parts, optimizing NC programming, realizing offline clamping and flexible CNC machining, the machining accuracy and efficiency of mold processing are effectively improved, and the equipment and labor costs are effectively controlled.

Some key technologies have been developed and applied in the project of manufacturing technology of mold forming zero group, which has laid a good foundation for the subsequent advanced technology.


Status quo

Mold moving punch, press plate, insert is an important working part in the mold, the original processing method is a single piece of CNC machining, a device each processing only a piece of insert, each piece needs to find once. The cycle and quality of insert processing directly affect the mold manufacturing cycle and quality.


Existing problem

1. The processing process of movable punch, press plate and insert is complex;
2. Due to the large number of inserts and the processing content of the press plate, it does not match the processing rhythm of the bottom plate and the slide block;
3. Due to inconsistent processing benchmarks, processing errors will accumulate, leading to frequent problems in the assembly process

The flexibility of the equipment is low, the operator's single auxiliary time is long, and the cost is large.

Core technology and innovation
Mold assembly (insert) fast clamping, accurate alignment technology
In view of the similar shape of the mold parts, the number of pieces and single processing, resulting in complex processing procedures, long time and high cost, through the development and application of the mold group technology once clamping, alignment technology, to achieve the group of pieces offline clamping, CNC equipment processing once to complete multiple insert processing.

The basis of the assembly clip is the screw hole of the part as instructed by the process, and then the two farthest screw holes of the part are selected, one is the positioning screw and the other is the installation screw, and the final clip is quickly installed in the T-slot; The precision alignment technology adopts the D10 reference pin on the mounting plate, adopts the principle of unified reference, reduces the accumulation of errors generated by single processing, and improves the processing accuracy.

Mold components (movable punch, press plate, slider) fast clamping, accurate alignment technology
The positioning of the movable punch and the press plate on the process mounting plate is based on the cross key, and the reference ball on the movable punch and the three-pin hole on the press plate are located.

Due to the large difference in shape, structure and size of the slider in the mold component parts, the original positioning method on the process mounting plate will cause the deformation of the slider because of the excessive clamping force; If the clamping force is insufficient, the workpiece is easy to loosen, and there will be processing and clamping plate, screw interference problems, in order to solve this problem, the use of double magnetic circuit conversion principle design of the new fixture, by electronic control device conversion magnetic circuit to achieve the magnetic force line in the system inside and outside the two cycles of conversion, to achieve the purpose of relaxation and clamping.

The above description is for the mold component parts (movable punch, press plate, slide) on the process mounting plate assembly clip and line accurate alignment technology, this technology provides a good prerequisite for the successful achievement of the subsequent project.

value
1. The processing of mold component parts has developed from single-piece processing to multi-piece processing, which has a milestone significance for the improvement of the ability of mold manufacturing;
2. Through the effective mastery of group processing technology, the operating ability can be greatly improved and the fatigue can be reduced;
3. Standardize the component processing process to enhance the management ability of on-site processing;
4. The key technology in the development of this technology has a good role in laying the groundwork for future projects and is sustainable.

Closing remarks
The group processing and manufacturing technology of mold components solves the processing and manufacturing problems of mold similar parts and mirror parts. Batch processing in group processing greatly simplifies the process flow, improves the CNC processing efficiency of the mold, improves the processing quality of the mold surface, shortens the mold manufacturing cycle, and reduces the labor intensity of the operator. Strict in the mold assembly pass rate achieved, for the subsequent mold debugging to win enough time; Automatic mold processing has become the mainstream trend of mold manufacturing, and the next step is to better serve the mature group processing technology for automatic mold processing.
