The machining quality of Pipe Fittings Mould includes two aspects: machining accuracy and surface quality. Machining accuracy is the degree of conformity between the actual size, shape and position of the machined part surface and the ideal geometric parameters required by drawings. It and machining error machining are both geometric parameters for measuring the machined surface of pipe fittings.
Usually, the machining accuracy of pipe fittings mould is measured by tolerance grade, and the smaller the grade value, the higher its accuracy; The machining error is expressed by numerical value, and the larger the numerical value, the greater the error. High machining accuracy means small machining error, and vice versa. It is necessary to know that the actual parameters obtained by any machining method are not absolutely accurate. From the function of parts, as long as the machining error is within the tolerance range required by the part drawing, the machining accuracy is considered. The surface quality of pipe fittings mould depends on the machining quality of parts and the assembly quality of machines. The machining quality of parts is also composed of machining accuracy and surface quality, and the main factor affecting machining accuracy is dimensional accuracy.
There are also the properties of the processing materials used for injection moulding of pipe fittings, which require high hardness of steel materials; At the same time, it is also required that the pipe fittings mould processing equipment have thermal stability and high reliability. For complex cavities and multifunctional compound mould, with the complexity of the shape of the parts, it is necessary to improve the design and manufacturing level of pipe fittings mould.
