Hydraulic mold opener HSB 20/50 of the injection molding machines

The hydraulic mold opener consists of a solid steel frame on which two slide plates are placed. These plates are driven by a pair of hydraulic barrels. Hydraulic barrels do opening and closing and at the same time the movable mounting plates move in a precise linear lines. The source of pressurized oil is separately standing hydraulic unit equipped with a pair of pumps. Regulation of the movement speed of the both plates is provided with a frequency converter and proportional valves which are placed on the hydraulic unit. The unit is also equipped with a separate circuit for controlling of the mold cores. After opening the mold, it is possible to work inside the mold. Safety plates protect the work area, so it is not possible to close the form when a person is standing between its halves. For safety reasons, the whole mold opener is placed in the protective fencing and access to this mold opener is possible only through the doors which are protected by an electric lock.

The hydraulic mold opener of the injection molding machines was designed for safe molds opening because of their control, cleaning and maintenance.
