The shape of the injection molded part and the analysis of the obstacle body elements, the injection mold structure scheme of Shanghai Mulan Injection Molding Processing Factory is determined based on the shape factors on the injection molded part that affect the mold structure scheme. These physical factors include: 'shape and obstacle', 'hole and groove', 'deformation and dislocation', 'movement and interference', 'appearance and defect' and 'plastic and batch'. In fact, each element can be divided into two sub-elements, so there should be 12 sub-elements in total. Two sub-elements in one element have both similarities and differences. For example, the obstacle body itself is a shape of the injection molded part, but the obstacle body is a shape that hinders the movement and shape processing of the mold member, and the shape only refers to the shape of the injection molding part. The shape inside and outside of the part, these shapes will not affect the movement and shape processing of the mold components. For example, a type hole refers to a circular or non-circular through hole and a blind hole, while a type groove refers to a non-circular blind hole. The six elements affect the structural scheme of the injection mold and the determination of various mechanisms and components to varying degrees. Therefore, it is necessary to analyze the shape of the injection molded parts before designing the injection mold. The design of the injection mold is based on the analysis of the 'six elements' of the shape of the injection molded part. Other cavity molds such as die-casting molds, rubber molds, foaming molds, and composite molding molds can only transition to the mold structure plan through the analysis of the 'six elements' of the molded parts. Formulation, in order to carry out the design and modeling of the mold.
The shape analysis of injection molded parts, in layman's terms, is to extract all the elements of the six elements from the shape analysis of injection molded parts. To extract all the elements in the shape of the injection molded part, it must be correct and complete. Therefore, the 'six elements' analysis is the basis and foundation of the structural design of the injection mold, and it is also the key to the structural design of the injection mold. Only when the 'six elements' of the injection molded parts are analyzed in place, can the design of the injection mold be in place. The so-called 'six elements' analysis in place means that the 'six elements' extracted from injection molded parts must be correct and complete. Just imagine, if there is a lack or error in the analysis of the 'six elements' of the shape of the injection molded part, can there be corresponding measures to solve the impact on the mold structure plan? Without the necessary measures, the mold structure plan can still be complete and correct So under the premise that the design of injection molded parts is correct, the analysis of the 'six elements' of the shape of the injection molded parts is the key to determine whether the mold structure is correct or not, so the analysis of the 'six elements' of the shape of the injection molded parts must not be underestimated. How to extract the 'six elements' of the shape of injection molded parts has certain methods and skills. The analysis diagram of the 'six elements' of the injection molded part is based on the parts diagram of the injection molded part, and the symbols of the 'six elements' of the injection molded part are marked on the positions of the elements according to the analysis results.
The shape and obstacle elements on the injection molded part are the main factors that the injection molded part affects the injection mold. The shape element on the injection molded part is the main factor that determines the shape, precision, quantity and size of the mold cavity and core, and the obstacle element is the main factor that determines the opening and closing of the injection mold, core pulling and the ejection movement of the injection molded part. Main factors affecting mold cavity and core processing. The structural design of the injection mold is related to the 'shape' of the injection molded part, and more related to the 'obstacle' on the injection molded part. The 'obstacle body' on the injection molded part is the factor that affects the mold structure scheme in the shape of the injection molded part.
The shape of injection molded parts and the analysis of obstacle body elements, due to the different functions and functions of injection molded parts in equipment, the shape, size and precision of injection molded parts are ever-changing. If the shape of the cavity and core of the molded injection molded part is the same as that of the injection molded part, since any object has the characteristics of thermal expansion, cooling and contraction, the cooling of the injection molded part must be smaller than the size required by the drawing. In order to meet the characteristic that the shape of the injection molded part will increase when the plastic is heated and expanded, Shanghai Mulan Injection Molding Factory needs to increase the shrinkage of the plastic for the size of the mold cavity and core. In this way, when the plastic is cooled in the mold, it can be guaranteed to be consistent with the drawing size of the injection molded part. The shape and size of injection molded parts mainly affect the shape and quantity of mold cavity and core and the selection of insert form; the setting of form, position and size of mold gating system; the selection of mold base form and size Selection of surface, core pulling mechanism and ejection mechanism of injection molded parts, etc. Any injection molded part has external or internal shape elements, otherwise it is not a solid injection molded part.
