In the field of mold manufacturing, the collaborative work of non-standard mold accessories and standard mold accessories is crucial, which is related to the efficient operation of the entire mold system and product quality.
First, the compatibility of dimensions and interfaces is the basic point to be considered during design. The dimensions of non-standard mold accessories must be precisely designed to ensure seamless connection with standard mold accessories. For example, when designing the ejector pin of a non-standard mold, its diameter and length must match the ejector pin hole on the standard mold base, and the tolerance range must be strictly controlled to ensure that the ejector pin can smoothly pass through the mold base and complete the ejection action during operation. For the interface part, whether it is a mechanical connection interface or a fluid channel interface, it must follow the general standard specifications or be consistent with the interface form of standard mold accessories. For example, the interface design of the cooling channel must ensure that the non-standard cooling pipeline can be smoothly connected with the cooling system of the standard mold to avoid leakage or poor flow.
Secondly, functional complementarity is the core of collaborative work. The design functions of non-standard mold accessories should complement those of standard mold accessories to improve the functions of the entire mold. For example, in an injection mold, standard cavities and cores complete the basic product molding shape, while non-standard design sliders or inclined tops are used to solve the molding problems of special structures such as undercuts and side holes. When designing these non-standard accessories, it is necessary to fully consider their action sequence and mutual coordination with standard accessories during mold closing, mold opening and molding. For example, the action stroke and speed of the slider should be coordinated with the opening and closing actions of the standard mold to ensure that the slider can accurately enter or exit the working position when the mold is opened and closed, and does not interfere with other standard accessories.
Furthermore, the matching of material properties and service life should not be ignored. The materials selected for non-standard mold accessories should match those of standard mold accessories in terms of hardness, strength, wear resistance and other properties. If the performance difference between the two is too large, it may cause a certain accessory to be damaged prematurely during the working process. For example, in a stamping mold, the standard punch and the non-standard design of the die material should have similar hardness and fatigue resistance. In this way, they can maintain a synchronized wear rate during the long-term stamping process, reduce the frequency of mold maintenance caused by damage to individual accessories, and thus improve the overall working life of the mold.
Finally, the dynamic balance of the system also needs to be considered during the design process. The mold will generate various dynamic forces during operation, such as clamping force, demolding force, etc. The design of non-standard mold accessories must ensure that the entire mold system can still maintain balance under the action of these forces. For example, when designing the support columns of non-standard molds, the position and number of support columns should be reasonably determined based on the overall structure of the mold and the distribution of other standard accessories, so that they can effectively share the clamping force, prevent the mold from deforming during operation, and ensure that standard mold accessories and non-standard mold accessories can work together in a stable working environment.
