Latch LocksDKLInternal Latch LockBasic selection and application design guidelines1. Select the appropriate internal latch lock size – 28 mm diameter (small), 34 mm diameter (medium), or 45 mm diameter(large) based on the width of the mold base. However, largemolds, thick plates or heavy load applications may require thenext largest size assembly than is specified.2. Select the appropriate travel range from the two choices foreach size. This selection is based on the specific applicationrequirements for the amount of travel that must occur at oneparting line prior to the latch being released. The total travelrequirements are based on the amount needed for the application as explained above, plus 3 mm minimum additionalallowance. This added 3 mm minimum will make sure the fullrequired travel has occurred before the latch lock starts itsreleasing action.3. Select the appropriate length for the center puller pin fromthe two choices for each size. The length of the pin is determined by the specific application including the mold base platethicknesses, where the pin will be mounted, etc. If possible,the center puller pin should be mounted in the support plate.However, some applications require the center puller pin to bemounted in the bottom clamping plate. This will depend on thetravel or the length of the split sleeve component which controls the travel and the plate thicknesses in the mold base.4. A minimum of four assemblies are recommended per mold.However,for larger molds, thick plates, or an application where loads arenear maximum, additional assemblies and/or next largest sizeassemblies may be required. An application must never exceedthe maximum recommended load values. A balanced loadmust be maintained to avoid cocking and binding which couldcause severe overloading. Only one size latch lock assemblyshould be used in each mold base.5. The center puller pin should be counterbored into its mounting plate 4 mm minimum for most applications, as shown inthe drawings at right. This counterbore aligns the center pullerpin with the other components in the assembly.6. It is important to make sure that the leader pin lengths inall applications are long enough to fully engage the stripperplate through its full travel. The latch lock mechanism latchestwo plates together but is not intended to provide guidance.Instead it relies on the leader pins in the mold for proper alignment and support of the actuated stripper plates.7. In the fully latched position the internal latch lock mechanism will allow movement of approximately 0.4 mm for the 28mm diameter and 34 mm diameter assemblies and approximately 0.5 mm for the 45 mm diameter assemblies.8. Injection molding machine mold opening speed may have tobe reduced in order to make sure that excessive shock loadingdoes not occur.9. The Internal Latch Lock is not recommended for severe loadapplications.10. The Internal Latch Lock must not be exposed to temperatures that exceed 150 C at any time.11. An optional sleeve can be added to the Latch Lock that provides two additional functions. However, this optional sleeveis not required for the Latch Lock function. The optional sleevecan be added to incorporate guided ejection and/or normalejector assembly return functions in the mold.www.diemouldequipment.com.au4 mmMin.Internal Latch Lock application with centerpuller pins mounted in the support plate.This is typically done in applications wherethe travel is shorter and/or when moldplates are thicker.4 mmMin.Internal Latch Lock application with centerpuller pin mounted in the bottom clampingplate.

Latch LocksDKLGuided Ejection SleeveAdd guided ejection and return pin functions to Internal Latch Lock mechanism with this optional sleeveThe optional Guided Ejection and Return Sleeves, although notrequired for the Internal Latch Lock, can add two functions tothe mold base that are typically required in most molds. Theseoptional sleeves can add guided ejection and ejector assemblyreturn functions to the mold base. Additionally, these addedfunctions fall within the space requirements of the plate latchingmechanism. However, these optional sleeves do not create anearly ejection return system that is occasionally required in someapplications. Sleeves can add guided ejection function to mold base alongwith plate latching mechanism Sleeves can replace function of return pins in mold base for mostapplications using the plate latching mechanism Sleeves fit around the center puller pin of the plate latchingmechanism and are mounted in the ejector assembly, thus eliminating the need for additional mold space usually required for theguided ejection and return pin functionsCut off only on this end;refer to note 1 below.L35L39L40 1.6 1D30 Dia. 0.02 0D29 D28 D30Dia.

Two-Stage EjectorsTSTL2-stage Ejector Top LastPositive, precise plate control:DME 2-stage Ejectors (TS) adapt to a number of mold base sizez and plate thicknesses. They are available in two ejection sequences: Top Last (TS) and BottomLast (BS). Each ejection sequence is available in three sizes to accommodatemost standard DME mold bases. The stroke range for each ejection stage isdetermined and fixed by the customer by cutting the Center Rod to the desiredlength (both TSTL and TSBL types) and by also cutting the Travel Sleeve to thedesired length (TSBL type only). Once installed, the DME 2-stage Ejector assurespositive, precise control of the sequence and distance of each stroke of the twoejector plates. Once installed, there are no adjustments that can be accidentallychanged.Benefits:Both the first stage and second stage strokes are set independently. Easy set-upand installation. Fixed strokes cannot be tampered with or accidentally modified.Internal installation avoids interferences with water line connectors and externally mounted components. Utilizes latching mechanism similar to DME InternalLatch lock for smooth operation and guidance. Three sizes, for each style, to choose from to accomadate most standard DME moldbases. Hardened steel components for long life. DME 2-stage Ejectors are considerably more compact and may be centrally located,the preferred method for locating DME 2-stage Ejetors is in pairs, offset from mold center. For more details, assembly guidelines seewww.dme.net.Selection and design guidelines:Select 20 mm Ø (small), 26 mm Ø (medium), or 23 mm Ø (large) 2-Stage Ejector based on the width of the mold base (large molds,thick plates or heavy load applications may require the next size assembly). Determine the travel range for each ejection stroke(first and second), being very careful not to exceed the maximum stroke specified for the chosen 2-Stage Ejector style and size.this selection is based on the specific application. In general, a minimum of two 2-stage Ejectors are required. For larger molds,thick plates, or a application where loads are near maximum, additional assemblies and/or larger assemblies may be required. Anapplication must never exceed the maximum recommended laod values. A balanced load must be maintained to avoid cockingand binding which could cause severe overloading. Only one size of 2-stage Ejectors should be used in each mold base.H1-Stroke 1H2-Stroke 2Basic centerrod d
