This paper focuses on the design of the injection molding machine, it is molding plastic parts is an important process equipment. Injection molding is the use of plastic extrudability and molding, the viscous flow state of melt in certain pressure closed mold molding has a certain shape and size of plastic products. In determining the mould structure, draw the mold assembly drawing, and to calculate. The last map die non-standard parts, after review the production manufacturing.29291

1. The introduction
1.1 topic background and significance
Injection molding machine is a kind of important plastic forming equipment, its products cover automobile, aviation, electrical appliances, light industry and other fields. The quality and the machine performance and process of plastic injection molding products, etc. Various performance parameters are closely related. In injection molding, temperature, pressure, displacement, velocity and other performance parameters is prompted a short shot, flash products, warp size and some shortcomings of the important factors. In order to improve the quality of injection molding products, accurate to obtain and adjust various performance parameters is very necessary. Traditional way of manual detection method, low measuring efficiency and precision is not high, the multi-parameter, quick change, etc has great limitations. With the development of computer technology and instrument technology, especially the national instruments (NI) in the mid - 1980 - s put forward the concept of virtual instrument, presented a test and measurement field a profound technological change. The so-called virtual instrument is on the computer as the core of hardware platform, its function design and definition, by the user has a virtual panel, its test function by the test software implementation of a computer data acquisition system. Because of the virtual instrument integration computer powerful computer processing power and instrument hardware of measurement, control, greatly improve the measurement accuracy and automation degree. However, in terms of a variety of computer data acquisition system, due to its hardware configuration, programming and designers have different design concept, the system reliability, operation convenience and application scope, etc. There are big differences. In the plastic industry, to high precision injection molding machine system and humanized special data acquisition system. To this end, we designed a set of multi-functional, multi-channel data acquisition system, the system with NI company's high-performance data acquisition card and signal conditioning module as the hardware platform, using today's most popular graphical programming environment Lab View as a software development tool, it can be on the injection molding machine performance and process parameters such as high-speed real-time data acquisition, and the data into a computer for analysis and processing in a timely manner, finally the results vividly displayed on a computer screen. In the process of programming, we always adhere to the humanized design concept, standing in the user's point of view, will be a lot of necessary configuration work open to the user, according to their own needs to be configured by the user, greatly improving the universality and flexibility of the system, the practice has proved that this data acquisition system has high measurement precision, reliable and steady work. Is a set of can be truly applied in the production or very good data acquisition in the process of scientific research platform, has the very good application prospect. The author thinks that, the data acquisition system for the future to further develop the other function modules, such as data analysis function module, fault diagnosis function module was built the good foundation.
2. The basic composition and working process of injection molding machine
With injection molding technology widespread application and development of the machine type is more, but it is one of the most representative plunger type and screw type two kinds.
