1, The clamping strength is different

If the force clamping part of the 20 160T injection molding machines is used on the die casting machine, the result is four broken head plates, three broken middle plates, one broken tail plate, and the broken Golin column. Compared with the injection molding machine, the injection molding machine has a faster injection speed, and the impact force is much larger, the impact force is large, and the kinetic energy is naturally larger. The speed of the injection molding machine is 0.22 meters. The speed of the injection piston of the die casting machine is several times higher than that of the injection molding machine, which is about five to ten meters. From the comparison of the piston speeds, it can be seen that the kinetic energy of the two is very different. For example, if you drive to the wall and step on the clutch, then the kinetic energy can only act on the wall. If you do not step on the clutch, the kinetic energy and the thrust of the engine will be superimposed. At this time, the hydraulic pressure and kinetic energy will be superimposed in the cavity, and the kinetic energy is actually not large, because the injection speed is equivalent to the speed of the human running, the key is to look at the buffer, and the kinetic energy may be released within one millisecond in the cavity. Of course, this It is not absolute, and kinetic energy may be released within ten milliseconds in the cavity. The difference in instantaneous release power is extremely obvious.

2, Die casting machine is a double pump

Compared with the double-pump die-casting machine, the injection molding machine is a single-pumping machine. Because the injection molding machine is in the form of high-pressure high-speed (high-speed relative to the displacement of the pump), the injection molding machine can only use a single-pulse large motor. Compared with the injection molding machine which can only use a single pump large motor, the injection molding machine is driven by the energy storage device. The oil storage time of the energy storage device is extremely short, and it is completed in about four seconds. The release time is extremely fast, about 100%. About two seconds. The other cylinders of the machine, high pressure and high speed do not appear at the same time. Therefore, the die casting machine uses a double pump, uses a high pressure small pump to deal with high pressure, and a low pressure large pump to deal with high speed. Theoretically, the motor power of the die casting machine is smaller than that of the injection molding machine.
