DME HYDRAULIC LOCKING CORE PULL CYLINDERS Specification No. ME-E32-0001(C)

Part No. HLCP-PS01 Page 2 of 12

MOLD DESIGN CONSIDERATIONS (continued):

must “shut off” against an opposing core wall or face, so that plastic flashing is avoided. For proper “shut-off” as described above, recommended preload

amounts are provided in this document. Adjust the spacers prior to final mold assembly. Ensure sufficient pocket clearance around the piston rod and

spacer disk is present for smooth operation.

 Positional alignment of the cylinder assembly is achieved by aligning the forward collet of the cylinder body (protrudes forward of the mounting flange)

into the mold plate via the outer diameter of the collet. The collet will protrude past the spacer disk. Rotational alignment of the overall assembly is

achieved via the mounting screws, as rotational alignment is only used to position the proximity sensors and hydraulic fitting connections and/or hoses

within the overall installation. The piston may freely rotate, therefore if rotational alignment of the sliding core is required, rotational alignment of the

sliding core must be achieved via other means.

 The positional alignment of the mold’s sliding core is not to be maintained by the cylinder assembly’s piston. The sliding core must have it’s own

provision for positional alignment within the mold plate.

 The suggested installation pocket details are based on the cylinder assembly being recessed into the side of the mold plate. It is possible to have the

cylinders assembly mounted fully “proud” of the side of the mold plate, however, positional alignment of the cylinder assembly to the mold plate requires

the forward collet (protruding forward of the mounting flange of the cylinder body) to be recessed partially into the side of the mold. Please adjust the

overall installation as required to fit your application, while maintaining minimum clearances for the hydraulic fitting connections and/or hoses, as well as

maintaining clearances for the proximity sensors. It is the responsibility of the mold designer and/or mold maker to select appropriate hydraulic fittings, as

well as provide necessary pocket clearances (where required) for the hydraulic fittings. Clearance for hydraulic service may need to accommodate hoses

or other features, in addition to the hydraulic fittings themselves. Standard hydraulic thread is NPTF type, but other types are available upon request.

 Please see Detail 3.4 for additional notes regarding necessary clearance needed to accommodate the proximity sensors.

 Mounting screws provided should not be modified (shortened). Ensure the tapped mounting holes are deep enough to ensure the screw heads can fully

seat on the mounting flange after the screws are installed fully and torque is applied.
