Problems solved by technology

[0002] During the injection molding process, due to changes in conditions such as temperature changes and flow channel blockages, there is a possibility of high injection pressure. This high pressure may cause serious consequences of damage to the mold or even the equipment.
If this high pressure is not effectively monitored and controlled, the normal production of the injection molding machine cannot be guaranteed, and even serious accidents will occur.

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] An injection pressure monitoring method for an all-electric injection molding machine, comprising the following steps:

[0023] (1) Initial setting of injection pressure monitoring value

[0024] Such as figure 1 is the initial state diagram for injection pressure monitoring, where:

[0025] (1) Line 5 is the initial pressure monitoring curve for injection pressure monitoring. The initial curve can be changed arbitrarily. In order not to affect the normal process, it is generally set to the maximum pressure of the machine system;

[0026] (2), "Pressure holding switching position" and "screw loosening position" are automatically collected from the customer's process settings, and automatically calculated and divided into 6 equal parts;

[0027] (3) "Monitoring pressure offset" is an artificial setting value, in order not to affect th...

Abstract

The invention relates to an injection pressure monitoring method of a full electric injection molding machine, comprising the following steps of: (1) setting of a monitoring initial curve for injection pressure, with the longitudinal coordinate of monitoring value of injection pressure and horizontal ordinate of injection position; (2) setting of a monitoring curve for injection pressure; and (3) monitoring of practical injection pressure. The method has the advantages that a stepped pressure monitoring curve is formed for a pressure curve in the normal injection process, therefore, in the practical production process, once the injection pressure reaches monitoring pressure, the injection molding machine stops the injection actions immediately and gives an alarm, thus effectively preventing serious results that the mold and equipment are damaged due to abnormal high pressure.

Description

technical field [0001] The invention relates to injection pressure monitoring of an all-electric injection molding machine. Background technique [0002] During the injection molding process, due to changes in conditions such as temperature changes and flow channel blockages, there is a possibility of high injection pressure. This high pressure may cause serious consequences of mold and even equipment damage. If this high pressure is not effectively monitored and controlled, the normal production of the injection molding machine cannot be guaranteed, and even serious accidents may occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a method for monitoring injection pressure of an all-electric injection molding machine, so that it can monitor the pressure in real time and prevent the occurrence of overpressure. [0004] The technical solution adopt...
