Embodiment approach
[0014] Please refer to Figure 4 , a preferred embodiment of the injection molding machine clamping control method of the present invention, comprising the following steps:
[0015] Step S101, the controller 30 controls the power supply 20 to charge the molds 52 and 53 so that the molds 52 and 53 are positively charged and negatively charged respectively;
[0016] Step S102, the controller 30 controls the driving unit 40 to make the movable mold base 51 move toward the fixed mold base 54 along the slide bars 55 and 56, so as to adjust the distance between the molds 52 and 53. distance;
[0017] Step S103, the controller 30 senses the voltage between the molds 52 and 53;
[0018] Step S105, the controller 30 judges whether the voltage between the molds 52 and 53 is zero, if the voltage between the molds 52 and 53 is equal to zero, it means that the movable mold base 51 and the fixed mold base 54 are clamped Complete; if the voltage between the molds 52 and 53 is not equal to...

The invention provides a mould-closing control system for an injection molding machine. The system comprises a power source, a controller, a driving unit, a first mould, a second mould, a moveable mould base and a fixed mould base, wherein the first mould is fixed on the moveable mould base, the second mould is fixed on the fixed mould base, the moveable mould base is insulated with the first mould, the fixed mould base is insulated with the second mould, and the controller controls the power source to charge the first mould and the second mould and is used for sensing voltage between the first mould and the second mould; when the voltage between the first mould and the second mould is not equal to zero, the controller controls the driving unit to enable the moveable mould base to move towards the fixed mould base so that the distance between the first mould and the second mould can be adjusted. The invention also provides a mould-closing control method utilizing the mould-closing control system for the injection molding machine.
Description
technical field [0001] The invention relates to a mold clamping control system and method for an injection molding machine. Background technique [0002] When adjusting the mold of the injection molding machine, the movable mold base must first be moved to the fixed mold base through the controller, so that the mold fixed on the movable mold base contacts the mold fixed on the fixed mold base, so that the injection molding machine After the mold clamping is completed, the clamping force is generated for subsequent operations. Traditional injection molding machines generally use sensors to detect the distance between the mold on the movable mold base and the mold on the fixed mold base, and then position the movable mold base and the fixed mold base at the mold clamping position according to the detection results . Due to the large error generated by the sensor during the detection process, the movable mold base and the fixed mold base of the injection molding machine canno...
