■ Features
Heat resistance … Compared with conventional products (PL) whose resin sleeves have heatproof temperature of 80°C, PLH can be used under temperature up to 120°C. Wear resistance … Because even force is applied in vertical direction through special bolt and ring, the center of resin sleeve is smoothly expanded, thus reducing the generation of abrasion powder. Interchangeability … PLH can be replaced with molds for which conventional products are used. Typical usage … The number of parting locks and mold weight for each size are equal to those of conventional products. • PLH is a 3–piece structure. Mount PLH so that the special bolt protrudes from the resin sleeve as shown in the figure. (Pin gate mark is on the bottom surface.) • In terms of shape characteristics, the bolt tightening torque is lower than that of conventional products, so keep it within 1/4 turn at single operation.
• Allows adjustment of friction between the base plate and resin sleeve by tightening/loosening the tapered bolt. • Made of a high grade nylon, this parting lock features excellent corrosion and heat resistance properties. The resin sleeve by itself has heat resistant temperature of 150°C. But use it at 80°C or less because the durability will be reduced due to tightening stress by the tapered bolt when used continuously. • Embed the resin sleeve about 3mm in the movable side die plate. • Create a hole on the fixed side die plate and finish it so that its internal surface roughness finishes within the range between 0.2 1.6 – . Also make sure to R–chamfer the inlet edge. The parting lock's durability becomes lower with a C–chamfered edge. • As to the hole's dimensional tolerance, aim at creating an H7 reamer hole for PL10, and an H7 reamer hole + 0.1 for PL13/16/20. • These R–chamfering and surface polishing processes can be omitted by using a PLBS bushing that is specially designed for use with this parting lock. • The required tension can be obtained by adjusting (tightening/ loosening) the lock's tapered bolt. E Do not lubricate this parting lock. Lubrication reduces its friction force and nullifies its function.
