The function of the clamping system of the high-speed snack box machine is to ensure that the mold is closed, opened and ejected. At the same time, after the mold is closed, the mold is provided with sufficient clamping force to resist the cavity pressure generated by the molten plastic entering the mold cavity, preventing the mold from cracking, which causes the defective status of the product. Fast food box high-speed machine mold clamping system mainly consists of mold clamping device, machine winch, mold adjustment mechanism, ejection mechanism, front and rear fixed template, mobile template, mold clamping cylinder and safety protection mechanism. Hydraulic system The function of the hydraulic transmission system is to realize that the fast food box high-speed machine provides power according to the various actions required by the process, and meets the pressure, speed, temperature and other requirements of the fast food box high-speed machine. It is mainly composed of various kinds of hydraulic components and hydraulic auxiliary components, of which the oil pump and the motor are the power source of the high-speed machine of the snack box. Various valves control oil pressure and flow to meet the requirements of the injection molding process.
