Precautions for plastic mold assembly: Different types of plastic molds and different types of molding plastics (the same mold) have different assembly methods due to different requirements for start and accuracy. Therefore, the assembly drawings and parts drawings should be carefully studied and analyzed before assembly. Determine the assembly benchmark by understanding the functions, characteristics and technical requirements of each part. After careful assembly, all the quality indicators of the product are reached, including the accuracy of the mold movement and other technical requirements in use. Assembly datum Assembly datum refers to the datum used to determine the relative position of parts or components in the product during the assembly process. It can be roughly divided into: core, cavity, insert and other main working parts are used as the assembly reference; the base surface of the guide post and guide sleeve or the mold template side is the assembly reference surface.
Assembly accuracy Assembly accuracy refers to geometric accuracy, machining accuracy, movement accuracy, etc. After the equipment is assembled. The assembly accuracy of the plastic mold includes: the mutual accuracy of various parts, such as distance dimensional accuracy, coaxiality, equality, perpendicularity, etc. Relative motion accuracy, such as transmission accuracy, linear motion and rotational motion accuracy; 3) Coordination accuracy and contact accuracy, such as matching clearance and interference contact conditions; The wall thickness of plastic molded parts. When making a new mold, the wall thickness of the molded part should be at the lower limit of the size.
