Are the DME Round Tapered Interlocks available in a front-loadable option?
Not at this time.
Are there general recommendations available over using a round tapered interlock versus a rectangular tapered interlock?
Yes. Rectangular tapered interlocks have a unique benefit of allowing plate growth either the X axis or Y axis of the mold (depending on the interlock’s orientation in the mold). Normally rectangular tapered interlocks are placed directly on the X or Y axis of the mold parting line. If you run one half of the mold (for example, the “B” half) significantly cooler than the other half of the mold, using rectangular tapered interlocks can accommodate for thermal expansion differences between the plates and still provide precise alignment. Note: Interlocks are used for very precise alignment of the parting line, to a greater extent than the mold’s leader pins. If you have to run the mold haves at significantly different temperatures, it is important to check the molded part dimensions to make sure that there is no adverse effect on the final molded part dimensional conformity, due to significant differences in mold half plate temperature.
Round tapered interlocks are recommended to be placed close to the center portion of the mold, to minimize on any potential impact of mold half plate temperatures. The round feature of round tapered interlocks means that there is less accommodation for thermal expansion differences between the two mold halves.
Where can I find installation instructions or specifications for DME Interlocks?
Packing slips are provided with side, top and X-style interlocks when ordered as replacement items by calling DME Customer Service or through your regional DME Sales Representative. If you order a DME Mold Base with side, top or X-style interlocks already installed, no packing slip is provided for the interlocks as the interlocks are already installed.
For round and rectangular tapered interlocks, machined pocket installation specifications are not provided in the DME Mold Components catalog. Instead, the outside dimensions of the components are provided, and mold makers are expected to fit to suit for the intended mold. Suggested installation methods are also shown and described in the DME Mold Components catalog. Please note that for round tapered interlocks, shoulder plates are offered and must be ordered separately.
For parting line interlocks (using left-hand and right-hand Gibs plus a center Male Interlock), machined pocket installation specifications are not provided in the DME Mold Components catalog. Instead, the outside dimensions of the components are provided and mold makers are expected to fit to suit for the intended mold.
