Hot runner temperature control and warning method and control system utilizing same

Abstract

The invention discloses a hot runner temperature control and a warning method for a one-mould-with-multi-cavity injection moulding mould and a control system utilizing the same. The method comprises respectively arranging a temperature sensor at the same position in a plurality of mould cavities of the injection moulding mould, selecting one of the mould cavities to serve as a standard mould cavity, and setting a standard filling time, during each filling, calculating a different value between the filling time of the mould cavities and the standard filling time through a computing control module to serve as the basis for controlling a temperature adjusting device to adjust the temperature of the hot runner and serve as the basis for controlling a warning device to start. Therefore, the hot runner temperature control and warning method and the control system utilizing the hot runner temperature control and warning method not only can eliminate the influence of the outer side environment, but also can fast achieve flow balance of multiple cavities so as to reduce development time of a product and maintain quality of the product.

Description

technical field [0001] The present invention relates to one-mold multi-cavity injection molding, in particular to a hot runner temperature control and warning method for a single-mold multi-cavity injection molding die and a control system using the method. Background technique [0002] With the rapid development of semiconductor, optoelectronic, communication and other industries, the market demand for light, thin, high-precision, compact consumer electronic products and optical product specifications is increasing. Therefore, injection molding factories at home and abroad have begun to pay attention to the production of multiple cavities in one mold. The advantage of technology is that it can manufacture products in large quantities in a short period of time, thereby reducing the cost of products. However, one-mold multi-cavity injection molding often has defects such as short shots, warping, and inconsistent finished product weights of each cavity due to unbalanced fillin...

Problems solved by technology

[0004] However, before the aforementioned method reaches multi-cavity flow equilibrium, a new average value will be generated every time filling, that is, the filling time standard will continue to change, and it is easily affected by external environment fluctuations; moreover, the equilibrium state produced The product may have deviations from the user's requirements, so the process parameters still need to be adjusted to make the product quality meet the requirements; To ensure the quality of the product, so there is room for improvement
