Whether the clamping force is optimized and whether the load is evenly distributed on the four drawbeads of the injection molding machine is an important index to evaluate the performance of the injection molding machine.In order to continuously improve the performance of the injection molding machine and the quality of the injection molding product, more and more Injection molding machine manufacturers to install the sensor rod method to ensure that the injection molding machine to obtain excellent performance.
Generally, only injection molding machines with uniform load distribution can ensure the molding quality of the products and prolong the service life of molds and injection molding machines.Obviously, parallelism plays an especially important role in the injection molding process.If the molds or molds are not parallel, Each tie rod is subject to different loads, which may cause the tie rod to rupture and interrupt production, which can be avoided if a sensor is installed on the injection molding machine.
The clamping force can be measured in the following ways:
Install the sensor on the surface or interior of the pull rod to measure the force of each pull rod. After the total force is obtained, the pulling force of all the pull rods is obtained, which is the clamping force.
Install the surface strain sensor on the elbow and indirectly measure the clamping force by measuring the crankshaft deformation.
Install a pressure sensor in the clamping cylinder to measure the clamping force by measuring the oil pressure.
Install surface strain sensors on the stencil and measure the clamping force indirectly by measuring the amount of deformation of the stencil.
