技术领域 technical field
本发明涉及一种注塑模具,具体是一种系列化产品用柔性变形组合式注塑模具,属于机械工程中的模具技术领域。 The invention relates to an injection mold, in particular to a flexible deformation combined injection mold for serialized products, which belongs to the technical field of molds in mechanical engineering.
背景技术 Background technique
注塑模具是生产塑料制品的重要机械装备。产品质量的好坏,精度的高低与之密切相关。随着3C(Computer,Communication,Consumer Electronic)产品的迅速发展,产品更新换代的速度也随之加快。 Injection mold is an important mechanical equipment for the production of plastic products. The quality of the product is closely related to the level of precision. With the rapid development of 3C (Computer, Communication, Consumer Electronic) products, the speed of product replacement is also accelerating.
现有技术领域的注塑模具大都是针对某一固定规格的产品而设计制造的,其模芯和模架都只适用于该产品的生产,不同型号产品需要设计不同的模芯甚至模架,通用性不强。对于系列化生产的产品,其规格、形状特征变化不大,如果一种产品有很多型号,而对每一种型号都去设计制造一种模具的话,必然需要设计制造出很多套模具,这样不仅增加了产品成本,而且生产塑料制件时需要经常更换不同的模具,降低了生产效率,同时造成产品的生产周期比较长,延误了产品占据市场的时间。 Most of the injection molds in the existing technical field are designed and manufactured for a product with a fixed specification. The mold core and mold base are only suitable for the production of this product. Different types of products need to design different mold cores and even mold bases. Sex is not strong. For products produced in series, their specifications and shape characteristics do not change much. If a product has many models, and if a mold is designed and manufactured for each model, it is necessary to design and manufacture many sets of molds. This will not only The product cost is increased, and different molds need to be replaced frequently when producing plastic parts, which reduces the production efficiency, and at the same time causes the production cycle of the product to be relatively long, delaying the time for the product to occupy the market.
因此一种结构简单、生产效率高的生产系列化产品的注塑模具的研制就显得非常必要。 Therefore, it is very necessary to develop an injection mold for producing serialized products with simple structure and high production efficiency.
