Description
Technical Field
The utility model belongs to the technical field of mould injection moulding, concretely relates to intelligent control system that prevention process of moulding plastics rises mould.
Background
Today, the rapid development of the industry, the injection molding of the mold becomes the basis of the industrial development. In the injection molding process, the mold expansion is a serious mold accident, the mold expansion can cause overlarge holding force of a product, the ejector pin is broken or pushed through when the product is ejected, a workpiece is damaged, and the maintenance cost is huge. However, the method for effectively preventing mold expansion can only monitor the maximum injection pressure and the injection time of the injection molding machine by controlling, and the two monitoring methods have the following defects:
firstly, the method comprises the following steps: the mold expansion is prevented by monitoring the maximum injection pressure. The injection molding process is divided into three stages, namely, an injection molding runner, an injection molding sprue and an injection molding filling product. However, the maximum pressure is generated in the whole process, and the maximum pressure is generated in the injection runner, the injection gate and the product filling process. What is actually required to monitor to prevent the die from expanding is the maximum pressure generated during the product filling phase. However, the maximum injection pressure of the whole process can be monitored by the current injection molding machine, and the maximum injection pressure cannot be distinguished at which stage, so that the defect exists.
Secondly, the method comprises the following steps: the mold expansion is prevented by monitoring the injection time. The injection time is the total time from the start of injection molding of the runner to the completion of filling during injection molding. In the injection molding process, due to batch change of resin materials, feed back proportion, uniformity of material mixing and the like, the injection time is generally monitored by increasing the actual injection time value by 0.05 s-0.1 s. Increments of less than 0.05s can lead to fatal starvation of the product, starvation of the material, etc. However, even if the increment monitoring is carried out for 0.05s at the minimum in the actual process, the die is expanded in the abnormal process, and huge die cost loss is caused.
