Husky FL-BASE03A User Manual

Mold Base Technologies
Our Mold Technologies team supplies a wide range of mold bases and mold accessories. From simple, strippable, closure mold bases to complex 2- and 4-level stack systems, we offer fully engineered and optimized mold base solutions featuring mold technologies such as the patented Rotating Ratchet Ring unscrewing system. With over 40 years of mold base experience with expertise in high cavitation and stack sys­tems for closure, medical, packaging and cutlery applications.
Each mold base includes:
• Precisely machined stainless steel plates
• Cooling channels sized for each application
• Balanced hydraulic and pneumatic functions for smooth plate actuation
• Calculated insert stack compression to extend insert life
• Front-mounted cavity and core designs for easy maintenance
• All accessories, including lift bars, latches, water connection kits and hardware
Each mold base is completely assembled and fully tested, mak­ing mold insert installation fast, simple and trouble-free.
PRODUCTS
Husky’s mold technology is built upon years of design experience paired with new product innovation. Husky offers many technologies to increase cavitation, reduce cycle times and produce better molded parts.
STACK MOLD BASES
We have pioneered stack technologies since the 1970s. Our stack mold bases feature balanced hot runners, robust link­age systems and rugged mold supports. Mold base plate actuation can be controlled through compact pneumatic or hydraulic systems and/or rocker arms in order to meet part ejection requirements. Husky’s stack mold bases substan­tially increase output while maintaining cycle times and part quality. In addition to conventional 2-level stack mold bases, Husky also offers the following stack technologies:
Stack platens convert similar individual molds into a single-stack mold.
Four-Level Stack Mold Bases — four-level stack molds virtually quadruple the output of an injection molding machine, with minimal increase in clamp tonnage relative to a single-face mold. Husky’s 4-level systems utilize dual sprue bars control­ling melt flow to both hot runners as well as a primary and secondary harmonic linkage system for advanced mold open­ing. Four-level systems are effective for parts with compatible part heights and shot sizes requiring simple ejection systems.
Stack Platens – The stack platen permits the consolidation of two single-face molds in one injection molding machine. This system delivers melt to a center platen via an offset sprue bar. The center platen is configured with a Euromap or SPI interface and transports melt to either side of the platen. This allows two similar individual molds to function as a sin­gle-stack mold, increasing machine output, reducing floor space requirements and utilizing existing tooling.
4-level stack molds quadruple output, without significant increase in clamp tonnage.
UNSCREWING MOLD BASES – ROTATING RATCHET RING
For parts that are unscrewed during ejection, Husky’s Rotating Ratchet Ring (RRR) mold bases provide a superior alternative to conventional unscrewing molds. The patented RRR design uses teeth in the ratchet ring to unscrew the molded part from a stationary core. The primary benefits of using a stationary core are larger cooling channels and no rotary seals. Additionally, the RRR design incorporates a unique unidirectional clutch on the drive gear. The clutch permits the ratchet ring to rotate in one direction to eject the part and allows the ring to idle during rack reset.
Larger cooling channels, no rotary seals and the unique clutch design of the
Rotating Ratchet Ring provide faster cycles with less maintenance.
Integrated servo swingchutes for fastest possible cycle times.
SWINGCHUTES
Husky’s patented swingchutes replace costly robotics for product handling. Swingchutes are actuated by cams or servo motors and are integrated directly into the mold base. Suction cups at the end of the swingchute arms grip the parts, remove them from the mold and place them into a stationary chute next to the mold.
GATE INSERTS
Properly designed gate inserts improve cycle time and gate quality. Correctly positioned and sized gate insert cooling lines provide the widest possible processing window with­out compromising gate quality. Accurate insert manufactur­ing and finishing ensures correct nozzle and cavity seal off, eliminating detrimental resin hang-up spots. Husky provides standard and custom gate inserts manufactured from hardened tool steel and designed for easy maintenance and optimal heat extraction.
WORKING WITH HUSKY
Ordering a mold base from Husky means one-stop shopping, full project management and single-source responsibility. We provide:
• Extensive mold base engineering expertise, including experience with closures, unscrewing systems, thinwall parts and cutlery
• Stack mold experience with 2- and 4-level stack mold bases, stack platens and offset stack systems to maximize machine output
• Rotating Ratchet Ring technology for unscrewing closures, providing faster cycles and reduced maintenance
• Manufacturing capacity to handle multi-mold orders and large plate production
Automated manufacturing cells provide capacity for large and multi-mold
projects.
Incorporating Husky mold bases into the mold is easy:
• You provide Husky with part drawing, including cavitation, machine tie bar and shutheight specifications
• Husky recommends mold base size and ejection system
• Husky furnishes a core/cavity stack installation drawing specific to the mold base
• Husky designs and manufactures a complete mold base with all necessary accessories
The moldmaker simply designs and manufactures the core/ cavity stacks, supplying only the fasteners and seals to install these components into the mold base.
Accurate bore alignment ensures extended mold insert life.
