Abstract

A dual mold spacer for use with a dual mold assembly is provided that includes a first side portion configured to engage a first side rail of the dual mold assembly. A second side portion is configured to engage a second side rail of the dual mold assembly. A body portion extends from the first side portion to the second side portion and is configured to be located between a press of the dual mold assembly and first and second molds of the dual mold assembly. The body portion is configured for being spaced from and free from engagement with the first and second molds.

First claim

What is claimed is:

1. A dual mold spacer for use with a dual mold assembly, comprising:
a first side portion that is configured to engage a first side rail of the dual mold assembly;
a second side portion that is configured to engage a second side rail of the dual mold assembly;
a body portion that extends from the first side portion to the second side portion, wherein the body portion is configured to be located between a press of the dual mold assembly and first and second molds of the dual mold assembly, wherein the body portion is configured for being spaced from and free from engagement with the first and second molds of the dual mold assembly;
wherein the first side portion is a first side bar, and wherein the second side portion is a second side bar;
wherein the first side bar defines a channel that extends in the longitudinal direction of the dual mold assembly, wherein the channel is configured for receiving a projection of the first side rail, wherein the channel extends from a first terminal end of the first side bar to a second terminal end of the first side bar such that the channel extends along an entire longitudinal length of the first side portion in the longitudinal direction;
wherein the channel of the first side portion is defined by a pair of flanges that are a longer flange and a shorter flange in which the longer flange is longer in a vertical direction of the dual mold assembly than the shorter flange, wherein the shorter flange is closer to the second side portion in a lateral direction of the dual mold assembly than the channel is to the second side portion in the lateral direction;
wherein the body portion has a lower surface that has a surface normal that is located between the first side portion and the second side portion in the lateral direction of the dual mold assembly that extends in the same direction as does the channel in the vertical direction of the dual mold assembly.

2. The dual mold spacer as set forth in claim 1 , wherein the body portion comprising at least one cross-bar.

3. The dual mold spacer as set forth in claim 2 , wherein the body portion has two cross-bars, wherein a first one of the cross-bars engages both the first side bar and the second side bar and extends from the first side bar to the second side bar;
wherein a second one of the cross-bars engages both the first side bar and the second side bar and extends from the first side bar to the second side bar, wherein the first cross-bar is spaced from and free from engagement with the second cross-bar in the longitudinal direction of the dual mold assembly.

4. The dual mold spacer as set forth in claim 3 , wherein the body portion has a third cross-bar that engages both the first side bar and the second side bar and extends from the first side bar to the second side bar, wherein the third cross-bar is located between the first cross-bar and the second cross-bar in the longitudinal direction of the dual mold assembly, and wherein the third cross-bar is spaced from and free from engagement with the first cross-bar in the longitudinal direction of the dual mold assembly, and wherein the third cross-bar is spaced from and free from engagement with the second cross-bar in the longitudinal direction of the dual mold assembly.

5. The dual mold spacer as set forth in claim 3 , wherein the first cross-bar is spaced from and free from engagement with the first and second terminal ends of the first side bar in the longitudinal direction of the dual mold assembly, and wherein the first cross-bar is spaced from and free from engagement with first and second terminal ends of the second side bar in the longitudinal direction of the dual mold assembly; and
wherein the second cross-bar is spaced from and free from engagement with the first and second terminal ends of the first side bar in the longitudinal direction of the dual mold assembly, and wherein the second cross-bar is spaced from and free from engagement with the first and second terminal ends of the second side bar in the longitudinal direction of the dual mold assembly.

6. The dual mold spacer as set forth in claim 2 , wherein the second side bar has a lower surface that is flat, wherein the flat lower surface of the second side bar is configured for engaging a flat upper surface of the second side rail.

7. The dual mold spacer as set forth in claim 2 , wherein each of the cross-bars defines a center rib groove that are configured for the receipt of a center rib of the dual mold assembly, wherein the center rib grooves are configured such that the center rib is spaced from and free from engagement with the cross-bars.

8. The dual mold spacer as set forth in claim 2 , wherein the cross-bars are located in the vertical direction of the dual mold assembly at a lower location than an upper surface of the first side bar, and wherein the cross-bars are located in the vertical direction of the dual mold assembly at a lower location than an upper surface of the second side bar.

9. The dual mold spacer as set forth in claim 1 , wherein the first side portion, the second side portion, and the body portion are all made of aluminum alloy.

10. The dual mold spacer as set forth in claim 1 , wherein the longitudinal length of the first side portion is less than a longitudinal length of a first mold of the dual mold assembly, wherein the longitudinal length of the first side portion is less than a longitudinal length of a second mold of the dual mold assembly; and
wherein a longitudinal length of the second side portion is less than the longitudinal length of the first mold, and wherein the longitudinal length of the second side portion is less than the longitudinal length of the second mold.

11. A dual mold spacer for use with a dual mold assembly, comprising:
a first side portion that is configured to engage a first side rail of the dual mold assembly;
a second side portion that is configured to engage a second side rail of the dual mold assembly;
a body portion that extends from the first side portion to the second side portion, wherein the body portion is configured to be located between a press of the dual mold assembly and first and second molds of the dual mold assembly, wherein the body portion is configured for being spaced from and free from engagement with the first and second molds of the dual mold assembly;
wherein the first side portion is a first side bar, and wherein the second side portion is a second side bar;
wherein the body portion comprising at least two cross-bars;
wherein each of the two cross-bars defines a center rib groove that are configured for the receipt of a center rib of the dual mold assembly, wherein the center rib grooves are configured such that the center rib is spaced from and free from engagement with the cross-bars, and wherein the center rib grooves are located between the first and second side bars in a lateral direction of the dual mold assembly and are aligned with one another in the lateral direction of the dual mold assembly.
