In the blink of an eye again at the end of May, at the end of the month, when the boss of Dongguan Plastic Mould Factory suffered a headache, because he had to pay wages, pay rent, pay suppliers, and all kinds of money, the pressure was not small. . Well, today's editor introduces the determination of the core and cavity structure for plastic mold manufacturing.
Molded parts are in direct contact with high-temperature, high-pressure plastics, and their quality directly affects the quality of the parts. Therefore, molding is required.
The parts have sufficient strength, stiffness, hardness, and wear resistance, should be made of high-quality mold steel, and should also be heat-treated to have a hardness of 50 to 55 HRC.
Cavity design: The cavity adopts an integral cavity. The integral cavity is directly processed on the cavity plate, has high strength and rigidity, and is not easily deformed during use.
Core design: The core structure design should also be an integral core, which can save expensive die steel and reduce processing.
