Description
Technical Field
The invention relates to the technical field of production dies, in particular to a production die with a thin-wall shaped plastic part.
Background
In daily life, the plastic injection molding product has very wide application, and along with the continuous development of society and technology, people have higher requirements on the plastic injection molding product, such as light weight, energy conservation, beautiful appearance, environmental protection, and low price in a word, and the plastic injection molding product needs to be high in quality. Under the requirements of the development speed of different applications of injection molding products and continuous cost reduction, various plastic part manufacturers are forced to develop and adopt new mold designs and production processes, and because certain products are special in use, certain parts of certain plastic parts need to be particularly thin and narrow, namely thin-wall parts, and as for the thin wall, no special standard definition is currently available in terms of the thickness of the thin wall of the plastic part, and the definition is usually called thin-wall plastic part with the thin wall thickness of less than 1.5 MM. The thin wall of the plastic part with the thin wall is thinner, and when the plastic part is manufactured and molded, the molten material of the plastic part flows through the thin wall part after entering the die cavity, and the temperature of the die is far lower than the temperature of the molten material. The melt temperature is drastically reduced and adheres to the mold surface to prevent further progress of the melt, so that the difficulty of injection filling is greatly increased, and therefore, the molding process conditions must be high speed and high pressure Gao Mowen during injection molding, and the method is only suitable for a few resin materials with good fluidity, such as PP, PVC, etc. Most resin materials such as PC, POM, PMMA, LCP and the like which have slightly poor fluidity cannot be manufactured and produced according to the above requirements. Therefore, the production of such plastic parts is limited to a few resin materials with good fluidity, and in order to obtain plastic parts with full filling, attractive appearance and up to standard performance, the injection molding process must require high speed and high pressure Gao Mowen to pass through the thin wall part, so that a plurality of problems inevitably occur: the molding injection is too fast, the pressure is too high, the mold temperature is too high, the defects such as peak, trapped air, scorch, bubbles and the like of the molded part can be caused, and if the defects are avoided, the molding injection speed, the pressure and the mold temperature are required to be reduced. However, once the speed, pressure and mold temperature are reduced, the thin-wall part of the plastic part is extremely easy to cool and solidify, so that the end of the plastic part is difficult to fill, defects such as insufficient filling, glue shortage and shrinkage occur, and the thin-wall shape and the molding process condition are mutually contradictory. Therefore, when the thin-wall plastic part is manufactured, most of resin materials with poor fluidity cannot be manufactured or the manufactured thin-wall plastic part is high in reject ratio and waste and finally high in production cost due to difficult filling and insufficient strength caused by the thin-wall part.
