Abstract


With the improved performance of plastic and die technology continues to evolve, more and more products have been replaced by plastic. But most of the injection mold grinding and repair, still using the traditional manual way behind, so that the final accuracy and efficiency of the mold greatly reduced. This design of the mold can be opened spotting test press mold, mold repair, assembly, you can simulate working conditions and conduct accurate and comprehensive examination, injection mold assembly to improve the efficiency of the repair mode, early detection of the design and manufacture of plastic injection molds issues in order to improve the mold promptly and fix shorten tryout time, reduce operator repair mode, test mode of labor intensity. In this paper, the problems injection mold and die spotting press the status quo, the first under plastic injection mold testing and assembly features, proposed for the injection molding die spotting presses trial design, and based on SolidWorks 3D modeling software created 1000KN mold Spotting a three-dimensional solid model test presses. Secondly, on the flip mechanism based on MATLAB movement and force analysis carried out to calculate the hydraulic cylinder elongation and flip flip angle of rotation between the table and the corresponding motion, force and angular velocity relationship. Analysis shows: Flip the process, acting on the flip cylinder rod into force on the tensile stress. In addition, the use of COSMOS / Motion motion analysis capabilities for turning mechanism motion simulation carried out to compare the uniform rotation and flip flip table uniform translational cylinder piston under the program of the two movements of the moving parts of the motion characteristics. Meanwhile, based on the finite element analysis software COSMOS / Works on racks and master cylinder static finite element analysis, based on static analysis of data to establish optimal design model to optimize the design of its structure, respectively. Master cylinder after the design has been optimized to reduce mass by 32%. Rack up 9.28 percent reduction in volume, gained more reasonable frame structure, thereby improving the die spotting press rack test force status. Finally, the die spotting test press machine hydraulic system is analyzed and calculated, and the use of hydraulic pipes on the hydraulic modeling software Routing piping system cabling, to a great extent as a substitute for the traditional design of the hydraulic system piping layout design verification process to ensure that the hydraulic lines routing rational structure, greatly shortening the design cycle.
