1 105 Benefits and Selection Table D-M-E s Internal Latch Lock Allows Precision Control of Mold Plate Latchg Operation D-M-E s unique ternally-mounted latch lock mechanism adapts a number of mold base sizes and plate thicknesses. It is available three sizes accoodate most standard D-M-E stripper plate mold bases. Two travel ranges and two center puller p lengths are available for each of the three latch lock sizes. Once stalled, D-M-E s ternal latch locks control the sequence of one partg le openg after the first partg le has traveled a predetermed distance. After stallation there are no adjustments that can be accidentally changed. The ternal latch locks are most coonly used on D-M-E AX-Series stripper plate mold bases but can be used on other D-M-E stripper plate mold bases as well. Three diameter sizes choose from 28, 34, and 45 dependg on the size of the mold and the application Two travel ranges and two center puller p lengths choose from for each of the three sizes Hardened steel components for longer life Latchg mechanism has built- travel limitation When latch is released, latchg cams hold released stripper plate fully traveled position Easy set-up of timg for latchg mechanism Internal stallation avoids terferences with water le connecrs and externally mounted components Basic Latch Size 28 (Small) 34 (Medium) 45 (Large) Internal Latch Lock Assembly Item Number See page 111 for formation regardg an additional option that provides guided ejection and return of the ejecr assembly with guided ejection and return sleeves. "T" Travel Range Mimum Maximum DKL DKL DKL DKL DKL DKL DKL DKL DKL DKL DKL DKL Supplied provide maximum travel with no cuff. To reduce travel between maximum and mimum, cut off slotted travel limitg sleeve on threaded end only per stallation data. Center Puller P Length Options Center puller p length ordered must be slightly longer than application requires. Moldmaker then cuts off as required. See stallation data. Recoended Maximum Standard D-M-E Mold Base Width D-M-E s ternal latch lock allows control of the mold plate openg sequence on mold bases with stripper plates. It enables one plate or group of plates be latched gether while the first partg le openg occurs. Then, after a predetermed amount of travel, the latch lock releases the latched plate or group of plates for the remag partg le or partg les open. Maximum Recoended Load Values (Per Ass'y.)

However, for larger molds, thick plates, or an application where loads are near maximum, additional assemblies and/or next largest size assemblies may be required. An application must never exceed the maximum recoended load values. A balanced load must be mataed avoid cockg and bdg, which could cause severe overloadg. Only one size latch lock assembly should be used each mold base. Internal Latch Lock Benefits and Selection Table Index

2 106 Internal Latch Lock Typical Application Design Guideles Basic Selection and Application Design Guideles Internal Latch Lock Typical Application Design Guideles 1. Select the appropriate ternal latch lock size 28 diameter (small), 34 diameter (medium), or 45 diameter (large) based on the width of the mold base, as dicated the chart on page 105. However, large molds, thick plates or heavy load applications may require the next largest size assembly than is specified. 2. Select the appropriate travel range from the two choices for each size the table on page 105. This selection is based on the specific application requirements for the amount of travel that must occur at one partg le prior the latch beg released. The tal travel requirements are based on the amount needed for the application as explaed above, plus 3 (.12") mimum additional allowance. This added 3 mimum will make sure the full required travel has occurred before the latch lock starts its releasg action. 3. Select the appropriate length for the center puller p from the two choices for each size the chart. The length of the p is determed by the specific application cludg the mold base plate thicknesses, where the p will be mounted, etc. If possible, the center puller p should be mounted the support plate. However, some applications require the center puller p be mounted the botm clampg plate. This will depend on the travel or the length of the split sleeve component which controls the travel and the plate thicknesses the mold base. 4. The answers the above items (1-3) should establish a specific item number assembly from the table on page A mimum of four assemblies are recoended per mold. However, for larger molds, thick plates, or an application where loads are near maximum, additional assemblies and/or next largest size assemblies may be required. An application must never exceed the maximum recoended load values. A balanced load must be mataed avoid cockg and bdg which could cause severe overloadg. Only one size latch lock assembly should be used each mold base. 6. The center puller p should be counterbored its mountg plate 4 (.157") mimum for most applications, as shown the drawgs at right. This counterbore aligns the center puller p with the other components the assembly. U.S. Patent No. 5,494, The most coon applications for the latch locks are for the D-M-E AX-Series stripper plate mold bases. However, many other types of stripper plate mold bases can also be used with this ternal plate latchg mechanism. It is important make sure that the leader p lengths all applications are long enough fully engage the stripper plate through its full travel. The latch lock mechanism latches two plates gether but is not tended provide guidance. Instead, it relies on the leader ps the mold for proper alignment and support of the actuated stripper plates. 8. In the fully latched position the ternal latch lock mechanism will allow movement of approximately 0.4 (.016") for the 28 diameter and 34 diameter assemblies and approximately 0.5 (.020") for the 45 diameter assemblies. 9. Injection moldg mache mold openg speed may have be reduced order make sure that excessive shock loadg does not occur. 10. The ternal latch lock is not recoended for severe load applications. 11. The ternal latch lock must not be exposed temperatures that exceed 150 C (300 F) at any time. 12. Lubricate all metal--metal contact areas itially and periodically as required. A good grade of moldmakers non-meltg type grease for the appropriate temperature should be used. 13. An optional sleeve can be added the latch lock that provides two additional functions. However, this optional sleeve is not required for the latch lock function. The optional sleeve can be added corporate guided ejection and/or normal ejecr assembly return functions the mold. Refer page 111 for specific formation regardg this sleeve option. Internal latch lock application with center puller ps mounted the support plate. This is typically done applications where the travel is shorter and/or when mold plates are thicker. D-M-E AX-Series mold base is shown this typical application. Internal latch lock application with center puller p mounted the botm clampg plate. This is typically done applications where the travel is longer and/or when mold plates are thner. (Some applications may require a thicker than standard botm clampg plate.) D-M-E AX-Series mold base is shown this typical application.

7 111 Optional Guided Ejection and Return Sleeves Add Guided Ejection and Return P Functions Internal Latch Lock Mechanism with the Optional Sleeve The optional Guided Ejection and Return Sleeves, although not required for the Internal Latch Lock, can add two functions the mold base that are typically required most molds. These optional sleeves can add guided ejection and ejecr assembly return functions the mold base. Additionally, these added functions fall with the space requirements of the plate latchg mechanism. However, these optional sleeves do not create an early ejection return system that is occasionally required some applications. Sleeves can add guided ejection function mold base along with plate latchg mechanism Sleeves can replace function of return ps mold base for most applications usg the plate latchg mechanism Sleeves fit around the center puller p of the plate latchg mechanism and are mounted the ejecr assembly, thus elimatg the need for additional mold space usually required for the guided ejection and return p functions Ø D28 Ø D29 Ø D30 L36 L Ø D28 L37 L38 L Ø D30 L40 Cut off only on this end; refer note 1 below Ø D Ø D28 L41 MIN U.S. Patent No. 5,494,435 OPTIONAL SLEEVES GUIDED EJECTION AND RETURN SLEEVE DIMENSIONS Latch Lock Assembly Component L35 Length D28 D29 D30 L36 Length L37 Thickness L38 Length L39 Length L40 Length L41 M Size Item Number Item No 28 DKL-2811, DKL-2812, DKL (Small) DKL-2821 & DKL-2822 DKL Internal Latch Lock Optional Guided Ejection and Return Sleeves 34 DKL-3411, DKL-3412, DKL (Medium) DKL-3421 & DKL-3422 DKL DKL-4511, DKL-4512, DKL (Large) DKL-4521 & DKL-4522 DKL NOTES: 1.

The center puller ps must support and guide the sleeves, as well as the ejecr assembly. The ps must have sufficient bearg surface contact as specified by dimension L41 mimum. 3. Additional bearg surface contact for the center puller ps may require a thicker botm clampg plate or the addition of another plate the botm of the mold for some applications. See stallation data. 4. A mimum of four assemblies are typically recoended per mold. However, for larger molds, thick plates, or an application where loads are near maximum, additional assemblies and/or next largest size assemblies may be required. An application must never exceed the maximum recoended load values. A balanced load must be mataed avoid cockg and bdg which could cause severe overloadg. Only one size latch lock assembly should be used each mold base.
