The hydraulic system that has obtained the invention patent is upgraded from the traditional open hydraulic system to a closed hydraulic system, and the respirator that exchanges the oil tank with air is removed, and the entire oil tank system adopts a closed structure. Avoid water vapor and tiny particles in the air from entering the hydraulic system. At the same time, the entire hydraulic system is equipped with three sets of high-precision filtration systems, which makes the hydraulic system cleaner as it is used, and the probability of hydraulic system valve stuck and wear is greatly reduced, and the service life of hydraulic oil is greatly improved. improve.

Host hydraulic system configuration: constant force hydraulic pump, hydraulic valve (German rexroth) imported, and the selection of the valve group with feedback, to ensure the speed and accuracy of the system and service life. Host electrical system configuration: the new version of SIEMENS 1500 control system. It extends the network connection with users to realize remote control, remote diagnosis, remote monitoring, remote data upload and other functions.

1. Servo drive with invention patent has the following obvious advantages over hydraulic drive (patent type: invention patent; Name of invention: a vertical parting molding machine; Patent number: ZL 2020 1 0320484.2) Pure electric molding machine has the advantages of hydraulic molding machine, so that the end user can reduce consumption and energy saving in each mold, and virtually reduce the start-up cost. To enable users to improve the boot time, reduce maintenance costs, reduce spare parts consumption, reduce environmental pollution, improve the working environment. 2. The guide rod, wear-resistant base plate and other wear-resistant parts are made of high hardness tungsten carbide surface treatment than the traditional chromium plating life increased by more than 10 times

The automatic core machine automatically puts the sand core into the back of the last sand mold, and the grating protection device ensures the safety and speed of the operator to put the sand core into the sand mold. The automatic new speed can reach 330 to/hour. The maximum thickness of the sand core can reach 250mm.
