Today in the editor I will tell you about the development prospects of providing blister-related? It doesn’t matter if you don’t understand it like this, so let me follow the editor of Shenzhen Yonghengsheng Blister Machine.
Blister products are processed by plastics. The principle of product generation is to heat the flat plastic hard sheet material to soften it, then use vacuum to absorb it on the mold surface, and then cool to form. Blister products are widely used. They are mainly used in electronics and electrical appliances. Industry, food industry, hardware tools, cosmetics industry, toy industry, daily necessities industry, medicine, health care products, automobiles, stationery, stationery, sports goods and other industries.
Blister products have been widespread throughout the country and involve all walks of life, making the blister industry spread rapidly in our country. Various blister manufacturers have sprung up in the motherland. Blister is not only widely used in various industries, but now people's daily life is also inseparable from it. The advantages of blister products make it more popular than other products. Some blister tableware is not only gorgeous but also beautiful in shape, and it is resistant to fall and wear.
Blister is also an indispensable raw material for mold processing for some mold lovers. For example, the blister boat mold is heated by a thin plastic sheet and then adsorbed on a special mold by a vacuum blister machine. When the temperature drops, the same plastic sleeve as the mold is made. This production process is very simple, and some mold lovers can do it by themselves. They can choose their favorite model to make at will, and create their own works by themselves. Because of this, blister has become one of their favorite products.
No matter it is in the streets and lanes, we can see blister products everywhere, and they have spread all over the country. It will take root in China forever with its unique performance.
From design to production of blister products is a very complicated process, which should include product conceptual design, overall mold design, mold structure design, mold parts manufacturing and processing, mold assembly, and molding production. In the meantime, some analysis simulations and checks are required. Traditional design and manufacturing methods cannot fully consider all these links. Now, computers have been used in all the above-mentioned links. With the help of the powerful tool of computer and advanced technology of CAD, these links can be organically combined, and the effect that cannot be obtained by manual method can be obtained.
1. Blister product design
The design of blister products needs to comprehensively consider product application requirements, positioning blister product structure and process characteristics, requirements for blister performance, requirements for mold structure and manufacturing process, molding equipment and production volume, production costs, etc. Influencing factors in various aspects. Due to the mutual influence of these factors, it is not easy to get a reasonable design plan for blister products. In traditional manual design methods, this complicated task is done by experienced designers. Because the factors considered cannot be comprehensive, the rationality of the design is often not ideal, and the efficiency of the design is not high.
In addition, choosing the best material for blister products is a very important and complex issue in conceptual design. There are many types of blister, and its performance indicators include many types in many aspects. In traditional design, designers rely on their own experience and consult relevant manuals and technical materials to make choices. They can only consider some major aspects of product requirements and material performance, and it is impossible to comprehensively weigh all factors. Therefore, it is generally not very satisfactory.
In recent years, people began to use KBS technology in the conceptual design and selection of blister products, and achieved good results.
Second, the overall design of the mold
The overall design of the mold is based on the shape, size, process requirements and production volume of the blister product to determine the overall structure of the mold, including the number of cavities, insert materials and lateral core pulling mechanism, pouring system, cooling system, and film release The structure of the mechanism, etc., but also choose the type of mold base and determine the specifications of the mold base and the requirements for molding equipment. The overall design of the mold belongs to the category of conceptual design and has a decisive influence on the entire design process and design results. However, it is highly experienced and needs to consider many factors and requirements. Therefore, the quality requirements of designers are high. In addition. Due to the complexity of the mold structure, the overall plan design is often revised repeatedly. The process of gradual optimization.
Now, the research on the flexible technology of mold structure CAD has attracted people's attention. Different solutions for assembly models, virtual parts and symbolic parts have been proposed, and some CAD systems for the overall design of injection molds have been developed. This system is an effective means for mold designers to express design ideas and repeatedly modify design schemes, thereby improving the rationality of design results and design efficiency.
The application of KBS technology in the overall design of molds has also become a hot research topic. This technology uses the design knowledge in the knowledge base, starting from the application requirements of the blister product, the characteristics and process characteristics of the blister used, and gradually inferring the various parts of the mold structure to obtain the overall design plan. At the same time, designers can also intervene in the system design process and play their leading decision-making role.
Three, analysis and simulation
The molding of blister products is a very complicated process. For a newly designed mold, it is difficult to determine whether it can produce fully qualified blister products based on experience alone. Only after repeated trials and mold repairs can it meet the requirements. It is difficult to completely avoid the scrapping of parts and even the entire mold. This leads to a long mold design and manufacturing cycle and cost deviation.
The computer is used to analyze, calculate and simulate the molding process, which can provide a theoretical basis for mold design or check the design plan, so that the designer can find some problems in the design before the tool is manufactured, so as to proceed early The necessary modifications. Today's viewing software generally has functions such as blister flow analysis simulation, cooling analysis simulation, and analysis and calculation of mold mechanical properties. It establishes a rheological mathematical model of blister based on the rheological characteristics of blister, simulates and analyzes the non-steady state and non-isothermal flow behavior of blister non-Newtonian fluid in the mold cavity based on fluid mechanics, and analyzes the plastic based on viscoelasticity theory. The pressure holding process and pressure loss of the melt in the runner and cavity are simulated and analyzed, and the heat exchange between the flow and cooling process of the blister melt is quantitatively divided according to the heat transfer, and the mechanical principle and finite element method are used to analyze The strength and stiffness analysis and calculation of molds and plastic products have achieved good results.
Fourth, mold manufacturing
Numerical control machine tools are commonly used in the manufacture of mold forming parts, and manual production methods are becoming history. With the application of CAD/CAM integrated system, the design result can be directly generated according to the processing procedure, and the continuous connection of the design and manufacturing process is realized, thereby further shortening the design and manufacturing cycle.
5. Production of blister products
In the production process of blister products, computers have already been used for process control, production automation and product quality have been further improved.
