Standard Components For Plastic Mold 2021

GUIDE FOR OIL–FREE SLIDE UNITS FOR LOOSE CORE–STANDARD TYPE–

■ How to mount ● The unit can be mounted from both the upper ejector plate and lower ejector plate.

■ Characteristics ① Compact Standard type (SCZN/SCZA) is more compact than SCY.

The unit can be mounted on an ejector plate in two ways: A and B. Use an appropriate bolt that corresponds to each way.

A ： Screwing the unit to the ejector plate • Mounting from the upper side

B ： Screwing it into the unit • Mounting from the upper side

② Precise and maintenance–free product • Realizes smooth movements of loose cores with high–accuracy process in vertical/horizontal way. • Reducing each clearance between the right and left side to 0.1mm allows precise core movements. (SCY is 0.5mm per side.) • When you want to use it with a loose clearance, please make the dowel hole pitch of the mold (size of W 1 in the catalog) 0.5mm–larger than the catalog value with no stopper. (Please remove the stopper before use.) • Further precise rotation of the trunnion unit allows extremely precise movements of the loose core. • Putting solid lubricants in three faces of the slide plate ensures long and stable performance with no oil supply in addition to superior wear resistance/high load capacity/burning resistance. Prior to mounting, please apply grease to the unit in order to protect initial scoring. • Angular pin is prevented from turning with a slotted key with a cubic structure.

• Cleat function Cleat function is in place in the trunnion unit, which allows an easy insert of the angular pin holder. • Interference prevention The compact angular pin holder prevents interference with the mold when it tilts. • Wider variation You can select mounting angle of the slide plate according to the finished product.

① A groove is additionally machined in the side face of the slide base in the same direction as the inclined groove (inner side) To prevent the unit from being installed on the die with the angle of inclination in reverse, a groove was added to enable the direction of the inclined groove to be checked externally. Note that a groove is not machined in the slide plate (A° = 0).

② The length of the slide base dowel hole is extended (D20, 25 and 30 only)

The length of the dowel hole is extended to enable an appropriate effective range for the dowel to be obtained even when a dowel pin drop prevention spring plug is used.

E Notes : Be sure to take measures to prevent the angular pin holder from falling off from the mold. • If the angular pin is not fixed to the angular pin holder, with a structure in which takes measures to prevent the angular pin holder from falling off (such as guide unit stopper), the angular pin holder could fall off when the mold tilts/turns over. Prior to mounting, be sure to take measures to prevent the angular pin holder from falling off from the mold. E Notes : Prior to mounting, be sure to apply running–in grease to the sliding surface.
