Embodiments of the present invention are directed to a tonnage regulating structure and a mold incorporating same. For example, a tonnage regulating structure (302, 1002, 1202) for use in a mold (502) of a molding machine, the mold (502) being associated with an opening clearance (520) between mold
Embodiments of the present invention are directed to a tonnage regulating structure and a mold incorporating same. For example, a tonnage regulating structure (302, 1002, 1202) for use in a mold (502) of a molding machine, the mold (502) being associated with an opening clearance (520) between mold faces in a mold closed and clamped configuration, is provided. The tonnage regulating structure (302) comprises a body (304, 1040, 1240) having a first height (306) in a resting configuration, the first height (306) selected to be larger than the opening clearance (520) between the mold faces in a mold closed and clamped configuration; the body (304, 1040, 1240) including a compensating structure (308), the compensating structure (308) for regulating, in use under applied clamp tonnage, the body (304, 1040, 1240) to a second height (320), the second height (320) being smaller than the first height (306).

1. A tonnage regulating structure for use in a mold of a molding machine to perform the function of absorbing and re-distributing a portion of a clamp force, the mold being associated with an opening clearance between mold faces in a mold closed and clamped configuration, the opening clearance being a distance between a cavity side mold face and a core side mold face, the tonnage regulating structure comprising: a body having a first height in a resting configuration, the first height selected to be larger than the opening clearance between the mold faces in a mold closed and clamped configuration;the body including a compensating structure, the compensating structure for regulating, in use under applied clamp tonnage, the body to a second height, the second height being smaller than the first height;wherein said compensating structure comprises a plurality of cut-out portions defined in the body, the plurality of cut-out portions is spaced along a height of the body such as to provide a degree of resiliency to the body. 2. The tonnage regulating structure of claim 1, wherein said second height substantially corresponds to the opening clearance between the mold faces in a mold closed and clamped configuration. 3. The tonnage regulating structure of claim 1, wherein said regulating is a controlled regulating by selecting the first height and a degree of resiliency of the compensating structure. 4. The tonnage regulating structure of claim 1, further comprising an aperture, defined therethrough, for accepting, in use, a fastener for coupling to one of the mold faces. 5. A mold for use in a molding machine, the mold comprising: a cavity portion including a cavity side mold face and a core portion including a core side mold face, the cavity portion and the core portion defining therebetween a molding cavity; the mold being associated with an opening clearance between the cavity side mold face and the core side mold face in a mold closed and clamped configuration, the opening clearance being a distance between the cavity side mold face and the core side mold face;a tonnage regulating structure to perform the function of absorbing and re-distributing a portion of a clamp force, the tonnage regulating structure including a body having a first height in a resting configuration, the first height selected to be larger than the opening clearance;the body including a compensating structure, the compensating structure for regulating, in use under applied clamp tonnage, the body to a second height, the second height being smaller than the first height;wherein said compensating structure comprises a plurality of cut-out portions defined in the body, the plurality of cut-out portions is spaced along a height of the body such as to provide a degree of resiliency to the body.
