The information of general design The topic of this graduation design is the annual output of 200000 sets of car front and rear bumpers injection molding workshop process design. Based on factors such as the conditions of use, the processing condition, establish standards for the bumper to bumper before number 327-807-217-L, rear bumper number 327-807-417-E, front bumper Numbers weight 3850 g, rear bumper Numbers weight 4400 g, product appearance size 1720 * 720 * 720 mm.
General context of the design are as follows: from the introduction to the description of the formula and processing methods, and out of the total process into extrusion equipment parts parameter design and calculation, determine the equipment selection, and then by the material balance and energy balance to the workshop process, economic accounting and workshop layout, one by one, will fully improve the design content.
In the introduction, mainly introduces the application and production status, the bumper and, from the Angle of utility and economic performance of several commonly used car bumper, finally confirmed the PP and EPDM as this design in the use of materials. At the same time, this chapter has been clear about the purpose of this design and meaning, and the design specifications, and the design is proposed to solve problems.
In formula design, first elaborated the formula and function of each composition was introduced in the components commonly used materials. According to the characteristics of the PP, combining with the physical and mechanical properties such as standards, for a better formula design. In the process of selecting the components, in addition to the need to meet PP physical and chemical properties, also considering the interaction of each component in the formula, raw material is relatively easy to take, the price is reasonable. Determine the number of copies between components. Finally, the comprehensive consideration, in the form of a list of formula design table is given.
Choose a chapter in the molding method. PP molding methods are introduced. Reaction injection mould molding and injection molding (RIM), analyze, and determine the reaction injection mould molding (RIM) as the design of the molding method. In the second section of this chapter, mainly introduces the reaction injection mould molding (RIM), the working principle and characteristics of the method.
In the production chapter. First, make sure the total process of the design, the production process to make the necessary description, general layout and production technology process is given. Secondly, according to the order according to the production process, which in turn is introduced and the design of each production process. Its main including molding compound preparation process, molding process, etc. Section, it should be said injection molding process is the key point of this chapter, this section in addition to the details for the production equipment and technology, also for injection molding with screw's nose and mouth in all kinds of parameter selection and design of the detailed, to meet the design requirements. Finally, based on the screw and obtained the best working point, the nose mouth mould parameter selection for equipment type selection and material balance part provides the choice basis.
