Today is November 24th, 20 years. Time flies, and it is almost the end of the year. The Dongguan Plastic Mould Factory was more or less affected by the epidemic in the first half of this year, and now it has basically improved in the second half of the year. But the losses caused during the epidemic were good enough for the second half of the year. By the way, I haven't shared the knowledge of plastic molds for you for several months. I have introduced you the knowledge of parting surface last time. Today, I will share with you the selection of parting surface in plastic mold design.
Regardless of the structure of the plastic part, which design method is adopted, the parting surface must be determined first, and the mold structure largely depends on the selection of the parting surface. In order to ensure the smooth parting of the plastic part, the main parting surface should first be selected at the largest contour of the shape of the plastic part. Generally, the plastic parts are plastic shells, and the surface quality requirements are high. When selecting the parting surface, according to the selection principle of the parting surface, it is considered that the appearance quality of the plastic part will not be affected, it is convenient to remove burrs and flashes, and it is helpful to eliminate the gas in the mold cavity. After the parting, the plastic part remains in the movable mold. On one side, it is easy to take out the plastic parts and other factors, and the parting surface should be selected at the largest part of the contour of the plastic part.
