Generally speaking, the components

Generally speaking, the components of the mold can be divided into two categories, namely, the movable mold and the fixed mold. It can also be understood as a male mold or a female mold. When the two molds receive force, they will be closed. The part in contact between the two in the state is called the parting surface. The parting surface can also be regarded as the parting surface of the workpiece such as the model and the part, and the meaning is more diversified. The parting surface is very important in the design stage, because the parting surface design has a direct impact on the product quality, the structure of the mold and even the ease of operation of the equipment. When determining the parting surface, the following should be followed. Point principle: First, the structure of the hand mold is complicated and difficult to operate, which affects the difficulty of processing and the lateral fractal, so the mold structure is required to be as simple as possible. Secondly, it provides strong conditions for the demolding of plastic parts. For example, when the mold is opened, the plastic parts should be kept on the edge of the movable mold as much as possible, which allows the ejection mechanism above the injection molding machine to be fully utilized, which greatly delays the lateral length The distance core pulls the phenomenon that the small mold size becomes smaller. The product needs to be guaranteed in terms of dimensional accuracy, and adjust the parts with accuracy requirements on a module as much as possible, so as to shorten the error of equipment and manufacturing. Finally, the smoothness of the cavity exhaust must be ensured. At this point, the smoothness of the cavity exhaust can be achieved by overlapping the parting surface with the surface wall of the filled cavity.
