Mold latch

Fiber reinforcement of polymers allows us to use them in engineering applications that were previously off limits, We use fiber reinforced injection moldings in many under-the-hood automotive applications, such as rocker box covers and front end modules, which support the radiator, cooling fan, and hood latch, that are subjected to a wide range of temperatures. 

Latch plate A plate used for retaining a removable mold core of relatively large diameter, or for holding insert-carrying pins on the upper part of a mold. Release of the pins or core is effected by moving the latch plate. 

Rigid permanent magnets have a smaller maiket than flexible magnets. These magnets are formed by injection molding or powder metallurgy methods. Major applications are in fractional-horsepower motors, TV components, toys, and latches. The binder for these molding compounds is often nylon.

Figure 6-29. A collapsible HDPE (Petrothene LY 656, from Quantum Chemical) foam shipping container injected molded by the J.I.T. Corp. of Southfield, Michigan. This is 114 cm x 122 cm X 86 cm (45 in. x 48 in. x 34 in.) high. It holds and delivers. 85 m (30 cu. ft.) of materials, but on the return it takes only. 28 m (10 cu. ft.), because of its plastic mechanical hinges and latches. Stacked three high, they can hold 1.8 metric tons (4,000 lbs.) in a shipping mode.

For demolding the multi-gate runner, an additional parting surface is needed. The mold now consists not only of "fixed plate and ejector plate but has an additional middle plate which is moved by latches and stopped by anchor bolts. The parting surface of the gate opens first.

Figure 10.17 illustrates a semiautomatic floating-plate (loose-plate) mold. The floating plate is a permanent component of the press. It has an opening at its center that will accommodate different size pots and plungers that are needed to fabricate different parts. The floating plate moves either by hydraulic or pneumatic force or by bolts/latches that are built into the mold. An important advantage of these molds is their low cost. 

In summary an all thermoplastic blow molded seatback molded in Dow s PC/ABS thermoplastic is able to meet all the FMVSS and ECE r ulations for different latch configurations. It is expected that plastic seatbacks will become more widespread in the future due to the capability to reduce weight and costs, while extending functionality and comfort.
