DME Company’s Helical Gear Stack Mold Centering Device product line—the HG48-2000—saves time and money in production with interchangeable housings and assemblies that simplify the design, installation, adjustment and maintenance of stack molds. The Helical Gear provides equal and synchronized parting line openings for two- or four-level stack molds. The devices work on standard, spin-stack and other types of stack molds.
Measurements for the new HG48-2000 are as follows: 48mm nominal outside diameter of helical gear; 2000mm (78.74”) standard maximum length of assembly; and 800mm (31.49”) standard maximum parting line opening per side.
The devices contain a double-helical gear shaft with a left-hand thread on one end, a right-hand thread on the other and two mating nuts that fit on the corresponding threads. The gear shaft is retained by a pair of tapered roller bearings in the bearing housings, and the nuts are held in the nut housings.
