Abstract: A socket information retrieval mechanism and information retrieving agent services on the basis of injection machines is proposed in this research. The proposed agent adapted customized packet format for client-server connection communication, and sent process parameters back to production process database constructed by this Institute. The production process data of injection machines can be accessed by the agent services pro-posed in any networking environment through standard services to construct a variety of systems for machine monitoring and information analysis. If an error occurs, remote machine diagnosis can be executed at once.

Abstract: The paper deals with the regranulate impact on the mechanical properties of fundamental material. It focuses on the mechanical properties analysis of materials with different regranulate content. To determine the mechanical properties we chose the tension test, which is one of primary mechanical properties tests.

Abstract: The analysis of motion and mechanics property has been studied on the five hinged incline arranged and double elbowed force increasing mechanism of injection machine in this paper. An optimization design is proposed on the force increasing mechanism by use of genetic simulated annealing algorithms. A complete procedure of optimal design is introduced so as to increase the stroke ratio and the amplification of the force, and to decrease the total length of mechanism, which belongs to multi-object optimization problem. Compared with the traditional methods, the result shows that the stroke ratio is increased, the amplification of the force is increased and the total length of mechanism is decreased. Moreover a sensitivity analysis of design parameters has been performed to see changes in injection performance parameters, and results show that the length of back elbowed bar and the length of connected bar have a significant impact on the performance measures. And the results recommend that the close clearance of the length of back elbowed bar and the length of connected bar must be maintained.

Abstract: The analysis of motion and mechanics property was carried out on the five hinged incline arranged and double elbowed force increasing mechanism of injection machine. A complete optimization designing procedure was carried out by improved ant colony algorithms, so as to increase the stroke ratio and the amplification of the force, and to decrease the total length of mechanism. Its optional mathematics model was established. The procedure of optimal design belongs to multi-object optimal problem. The optimal solution of the force increasing mechanism was found with improved ant colony algorithms. Compared with the traditional methods, the result shows that the total length of mechanism is decreased, the stroke ratio is increased, and the amplification of the force is increased. Furthermore, a sensitivity analysis of various design parameters has been performed to observe changes in injection performance parameters, and results show that the length of back elbowed bar and the length of connected bar have a significant impact on the performance measures. And the results recommend that the close clearance of the length of back elbowed bar and the length of connected bar must be maintained. Therefore it can provide some valuable instruction and theory to engineers. The instance of 1000 N large-scale injection molding machine is taken as an example to demonstrated that such method is effective and practical.

Abstract: The paper is to simulate and analyze the mechanical behavior of the clamp system of an injection molding machine. Different commercial simulation tools are combined to create complete model of the system. The flexibility of several components is included by importing a FE model generated in ANSYS. Then the dynamic characters are presented in MBS software ADAMS. The mechanical behavior of connecting bars, tie bars were analyzed and quantified in order to work out improvements. The results show that the rear link and tie bar were the weakest parts in terms of safety.
