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

Part No. HLCP-PS01 Page 1 of 12

IMPORTANT SAFETY INFORMATION

1. To avoid injury, exercise caution by reading these instructions before servicing or operating the system.

2. These instructions must be passed on to the end user where they should be read before using this product. Failure to do so can result in injury.

Failure to comply can result in injury:

STORED ENERGY HAZARD

1. This product maintains hydraulic pressure during normal operation in both full back (retracted) and full forward (extended) position of the cylinder

assembly’s piston. Use caution when operating and servicing the system. Proper protective equipment, including eye protection, must be worn.

2. Hydraulic service to the cylinder assembly must not exceed 3625 PSI hydraulic pressure.

Failure to comply can result in improper equipment operation or damage:

1. The DME Hydraulic Locking Core Pull Cylinder (HLCP) assembly includes two inductive proximity sensors at low power. The proximity sensors require

power to deliver a signal. It is the responsibility of the customer to provide proper electrical service for sensor operation.

2. The proximity sensors require proper adjustment while installing into the cylinder assembly, as each sensor must be installed to a different depth. Please

follow the provided sensor installation instructions properly, or else the cylinder may not operate properly, or, the sensors will fail to detect the proper

position of the piston.

3. The proximity sensors are available in two types: NPN (standard) or PNP (optional). If PNP type is required, this must specified at system order.

Electrical wire-up schematics are provided for both types in this document. Please follow the proper wire-up for the proximity sensor.

4. If the proximity sensors are not used, it is always important to monitor the position of the sliding core. External limit switches may be used if the machine

cannot deliver power to the sensors, or where the service temperature of the proximity sensors is expected to be exceeded, or in cases were an elevated

level of magnetism or electrical current is expected to be in close proximity to the sensors. For proper system function, it is important that full forward

(extended) position as well as the full reverse (retracted) position of the piston (or sliding core) be monitored.

5. If using the proximity sensors provided with this device, do not exceed the maximum service temperature of 176°F (80° C).

6. When using external limit switches in the mold instead of the proximity sensors supplied with this product, the maximum service temperature of this

device is 356°F (180° C).

7. A minimum of 870 PSI holding pressure (hydraulic service) is required at all times. If the 870 PSI holding pressure is not maintained while the piston is in

full forward (extended position), the piston may not remain locked in forward position within the cylinder assembly.

8. The Mold Designer and/or Mold Maker is required to select the proper size of cylinder assembly in order to counter load that will act on the sliding core

due to plastic injection pressure within the mold cavity. Improperly selected cylinder assembly size can result in molded part flash or damage to the mold

during operation.

9. When selecting the appropriate size of cylinder assembly, take care to account for the necessary preload when the sliding core needs to shut off on an

opposing core face inside the mold. Load capacity of the cylinder assembly is reduced when preload of the sliding core is required. The recommended

preloads for each cylinder assembly size are provided in this document, as well as load capacities for both with and without preload.

10. The piston rod is not to be used as the sliding core itself. Do not modify the piston rod in any way. The piston rod is intended to be attached to the sliding

core in the mold, and it is the responsibility of the mold designer and/or mold maker to select appropriate sliding core design for the intended application.

MOLD DESIGN CONSIDERATIONS:

 This product is available in several sizes, and each size has a two available “standard” stroke lengths. If you require a stroke that is different than the

available standard strokes, then a non-standard stroke design is required. When ordering this product, please specify the required stroke if the standard

strokes available are not suitable for the intended application.

 This product maintains a sliding core in full back (retracted) or full forward (extended) positions. In order for the cylinder assembly to “lock”, the piston

must be full extended forward.

 This product includes a spacer disk. The spacer disk is placed between the front of the body flange and pocket installation. The mold maker must grind

the spacer disk to ensure proper fit at the desired mold operation temperature. The adjustment of the spacer disk is important for when the sliding core

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.
