In the past 10 years, China’s automobile market has developed rapidly and has become the world’s largest automobile consumer market. The entire automotive industry is ushering in new development opportunities. The growth of the automotive industry has also driven the development of the entire industry chain. For example, the auto parts industry. In recent years, the demand for plastic products in the auto industry has increased, and many auto parts have begun to use plastic products. Instead, the quality of plastic parts is particularly important. The quality of plastic parts is determined by injection molds. How to design auto parts molds is a problem that every molder needs to consider, so design a set of high-quality auto molds What details need to be paid attention to?
1. Simplify the design
The design of plastic products is a key stage in the design of automotive injection molds. For the design of plastic products, it is necessary to simplify the plastic product model as much as possible. The simplified design scheme is a clearly proposed regulation for each optimization stage of plastic products. Consider the basic regulations of important links, such as the thickness design of automobile injection molds, try to make the thickness of the mold symmetrical to prevent the occurrence of suitable uneven thickness.
2. Pay attention to the standard compressive strength
The compressive strength and strength should be regulated to a certain degree. Otherwise, the construction quality cannot be withstood by friction. The strength requirement must not be less than HRC35. A few special requirements are specified above 50～52HRC. Plastic products are After forming, the surface layer should be glossy, which can be finished by grinding and polishing.
3. Choose the parting line and parting surface of automobile injection mold
The clear method of the parting line can be clarified according to the appearance of the part. The function of the fractal line is just to divide the product into two parts, and the boundary line is the same. It is divided into two parts and located in the fixed mold forming, while the movable mold forming is the other part. To obtain the parting surface of the automobile injection mold, you can use the fractal line, and use the fractal line to scan the parting surface of the mold around multiple molds.
4. Frequently asked questions about parting surface design
One aspect of the parting surface of automobile injection molds must be paid attention to, that is, to ensure that each of the same inclined surfaces has a sealed spacing, and the effectiveness of the spacing must be ensured, so that the plastic melt will not be lost casually during the entire injection process. The name of the sealing material spacing is matched by this efficiency, which can seal the material. In the whole process of establishing the parting surface, if you encounter a parting surface with a slope or slope and its steps with a large difference in height-to-width ratio, whether it is one or several, be sure to set a standard plan for it, which can be beneficial Production processing and measurement.
