Based on 01 injection mold, the development of human 0-dimensional standard parts library He Liping, Liu Zijian Hunan University, people, 7, 搿 dad line model, milling and frying 82, in the wide programming environment, how to shoot based on 01 skills, shoot In the injection mold (3) remaining type, the standard library is not developed on the basis of the establishment of standard data, by calling, the disc office provides the dish object model. Implement the dimension parameter model. And automatically generate the standard shape of the standard parts, for the establishment of injection molding dimension 1 system planing conditions Introduction The diversified development of the mold industry makes the general mold, software can no longer fully meet the special needs of enterprises. Therefore, the research on the basis of the general-purpose software is the last time the development of the enterprise from the small model 1 system is necessary, special, 0 software must be combined with the actual situation of the enterprise, establish a mold standard parts library mold that meets the national standard industry standards and enterprise standards. General structure library and standard mold base library. In the implementation of the standard library, the corresponding data observing system is established to improve the current dimension of the entity. The software is gradually developed, and the sub-development of the software is also the result of our research. . Need to pay the current situation of China's small and medium-sized enterprises based on the microcomputer platform, select 5, Jia, spit 8 as the secondary development platform. 5, plus, the soil 8 uses the same underlying core with Qiu 108, 1380, its core technology Windows3l`JjlT generated, is conducive to the realization of secondary development technology.

Technical Overview Object Linking and Embedding. Ten. 1 stop 3! ; 1 is not another programming skill but a kind of programming mode technology rooted in Jia 8 environment, the core of which is to allow one, should, and order to meet the force of the secret object. Pull and operation, the 4, the goods 8 call is called the program to expose its own object architecture for the caller reference. Through technology, many object-oriented weaving scales such as 3vc, 8 people, etc. and applications can be combined with 5, Xianjie, and 8di, thus splicing and manipulating 8, compiling with corpse programs to meet design needs, such as menu design standard parts library The establishment of parametric design, etc. 28, the object model tree for secondary development, are carried out by calling the 3 broadcast, 1 object architecture. Base, 0 technology 8, body, 1. Put 3, with rain, 1. Various functions are packaged in 8, 1.1 objects for programming calls. As an object, it includes the type of image with several square blood 1; 2 the attribute method of the object 3 object, the hair piece creates its own application by manipulating the genus 1 of the image and calling the object, realizing the sub-development . For example, if you create a cuboid to access the part entity model, then 8, the heart rain, 1. Provide the image type, which contains the entity entity Canzhou 31 return entity feature name.

3, Hong 1 Jia 08 development system 1 does not.

Face we give 8, similar, such as the establishment of the object model tree 3 database design reasonable standard parts database management, will greatly facilitate the development of injection shuttle 21 system. The database is used to manage the standard parts of the injection mold. The standard part data is stored in the database in the form of a fixed data structure. Management of relational databases by data symbols can be applied to data types of relational structures.

Therefore, considering the assembly relationship of the injection mold, selecting the relational database in the database of establishing the standard part of the injection mold will facilitate the management of various standard parts in the assembly model. Based on the establishment of a standardized standard parts database. The interface program is developed by the program language of the face-to-face image. Realize the communication between the data bucket and the 5,1 grasping entity modeling, so that the required standard parts can be directly generated by calling the database, and various management of the standard parts can be realized through the management database.

4 object-oriented development environment through the compilation of 4 dynamic links for filed 31 131.; 7, file, file 8, capture, 1.1 loading up, can achieve the development of 5, anvil, spit 8 bottom. For example, writing a menu file directly hangs on the 3, like the menu, such as the menu, forming a system that should be programmed and torn!

In order to access 8 also provide the entity object. It is more intuitive to use it to write parametric design programs and to call the database interface program. We can make full use of the advantages of these object-oriented programming languages ​​to achieve the next development of the injection mold 00 system. 3 is to use the object-oriented programming language 0, by calling 3, the menu resource object model provided to achieve the sub-development menu design.

Cao Na, using the butterfly to guide the bribery to change the technique, automatically generate the dimension, for the mold designer to call as an example, to illustrate the development of the 0-dimensional 0-dimensional standard library of the injection mold based on the 01 technology under the 3,14 platform. .

Firstly, in the 5, 8-like modeling environment, the limit nail model with the national standard series size as the driving parameter is established. Secondly, the limit nail national standard library is established in the relational database; then, the programming interface is designed by using 8 Access the database, and call 5 at the same time, as in the class, the class 1 object realizes the parameterized drawing of the limit pin.

Finally, use, compile the menu file, load it up at runtime, and implement the menu.

An example of the next development using the 5, such as the provided 0, in the 8 environment is given below. In 6 visit 3, heart 1 Jia, 1 know the object code limit, limit nail basic size 0 technology and later developed the network version of the object link and embedding technology out 6, the technology is a major object-oriented programming technology progress. The use of 0 people 0 technology is also increasingly widespread. The latest version, the human, the software system supports this from the human wheel, and enters the parameter in the field other than the arc of the sentence. First select the tool. In order to get better processing results, here choose a ball cutter with a diameter of 16.

Choose the way of the knife, there is a choice, into the sweat, radiation cutting. Here, it is like a 01-radiation cutting. Its step is to increase the angle by the center angle; LKlCREMKMii0fy0.3. The system also gives the starting angle and the ending angle, and the programmer can freely define the starting and ending positions. The position of the radiation point system defaults to the coordinate origin.耵, defined in 60; axis point.

There are some processing methods, such as 0-way two-way signal. This is to improve the efficiency of the choice of 7 processing and finally define the margin value and processing accuracy. Because it is finishing, the precision is higher.

The calculation results in a side finishing process of 5.

3 volumes, 1 surface milling can not only process free-form surfaces, but also use it to calculate the machining plane. It can also receive good results. Take the bottom plane as an example to take the intersection of the bottom plane and other curved surfaces, and define the area inside the line as Processing range, select, 0 select the tool as the slot cutter with diameter 161, define the cutter mode as 31-like spiral cutting, the step distance is 10mm, select the bidirectional machining pass mode; 1 define the machining allowance to 0, the machining precision is 0.02. In the same way, this method can be used to define the upper part of the machining intermediate boss part, and the calculation can obtain the 6-plane finishing process.

At this point, the stage of NC machining is basically finished, but there is also a part between the waist-shaped boss and the round table that the CNC machine tool cannot process in place. It can only be achieved by CNC machining of the electrode and by EDM.

Through this example, the NC machining process of a workpiece is basically performed, and the processing process of other complicated cavity cores is roughly the same. In the next issue, some other programming methods and techniques will be introduced.
