Description
What are Latch Locking Units?
The latch locking unit is a kind of clamping device, which is used to fix the die mold. It is widely used in stamping molds, die-casting molds, automotive parts, and equipment manufacturing industries. There are certain requirements for the material selection and processing technology of the mold clamping buckle.
Noted: The latch lock device design is simple, easy to install, and highly reliable in operation.
Latch locking units are used primarily on injection molds with multiple plate movements. They can be subject to particularly high loads as a function of the component dimensions and the size of the mold.
With its extensive range of latch-locking units, DGMF offers a variety of options for solving complex applications on a customized basis.
Latch locking units include lock devices Z170/, Z171/, Z173, and Z174/…, which now have a DLC coating on their functional surfaces, which is said to keep friction and wear down to a minimum. They are especially suited to use in the food and medical sectors, since production can be run without lubricants, making it compatible with a cleanroom environment.
The coating does not lead to any dimensional changes in the functional surfaces, hence the new latch locking units can be fitted 1:1 to existing systems. The latch locking units show good slip properties, due to the low coefficients of friction, and show high corrosion protection.
Tested and tested with Z171 can be used in two.

The mechanical interlock design is safe and reliable; this Latch Locking Unit Z170 not only has the function of controlling the mold opening sequence but also can control the order of clamping; the tail end of the plunger adopts high-frequency annealing treatment to facilitate the secondary processing of the mounting hole.
MISUMI standard: PLS PLM PLL MPLK MLK MLKC latch locks
During the closing and opening of injection molds, the requirements for a snap-off machine are accurate and reliable, with low noise and impact.
The MISUMI standard Latch Locks PLS/PLM/PLL is a high-performance latch consisting of 7 parts (excluding screws and locating pins) and is characterized by: Compact and small size of the latch.
Accurate mold opening sequence with no reaction forces. There is no clamping load at all and it can be applied to low-pressure clamping molding. Its action has nothing to do with the mold closing sequence. If the runner push plate closes before the parting surface, the clamping block will retract by itself, so there is no need to worry about interference.
Usage of MISUMI standard Latch Locks
When using, it is important to note that these machines should be used in pairs and installed symmetrically. Two or four sets are commonly used.
PLS is suitable for molds up to 1.0 tonne with 2 sets installed; PLM is suitable for molds up to 1.8 tonne with 2 sets installed; PLL is suitable for molds up to 4.0 tonne with 2 sets installed.
