System of forming a protective covering for a wire harness
View Patent ↗A motion-powered liquid sprayer that can increase the number of rotations of the pump relative to each rotation of the wheel or axle is provided. The sprayer can include a gearing assembly that employs gears to increase the number of pump revolutions as a function of the wheel or axle rotation. The sprayer can also include a gear pump that employs an over-capacity or enhanced gullet together with blow-by spacing to control consistent liquid flow relative to variable motional velocities. Further, the sprayer can include a vertically adjustable nozzle as well as a free reverse rotation wheel hub.
1. A system that forms a wire harness covering according to a predetermined three-dimensional geometry, comprising:
a wire harness;
an injection mold that includes two mold halves that define a cavity therebetween and that is substantially flat in shape that forms a partially-cured wire harness covering having an intermediate, substantially two-dimensional shape; and
a post-molding fixture that orients the partially-cured wire harness covering in accordance with the predetermined three-dimensional geometry,
wherein the partially-cured wire harness covering is positioned in the post-molding fixture within a first predetermined time after forming the partially-cured wire harness covering, and
wherein the cavity comprises sub-cavities that form a corrugated covering of a predetermined thickness for the wire harness.
2. The system of claim 1 , wherein the post-molding fixture comprises a base with a plurality of guide members that project from the base that orients the wire harness in accordance with the predetermined three-dimensional geometry.
3. The system of claim 2 , wherein the plurality of guide members are pins.
4. The system of claim 3 , wherein the pins are disposed in pin receiving holes in the base.
5. The system of claim 4 , wherein a subset of the pin receiving holes are arranged about the base according to a predetermined configuration.
6. The system of claim 2 , wherein the guide members are walls.
7. The system of claim 6 , wherein the base has a top surface and the walls are upstanding from the top surface.
8. The system of claim 6 , wherein at least one of the walls has a tab protruding from the at least one wall.
9. The system of claim 1 , wherein the post-molding fixture is made from one of wood, fiberglass, composite, metal, alloy, or cardboard.
10. The system of claim 1 wherein the post-molding fixture comprises a tie that engages two portions of the harness for holding the harness in a fixed position while the covering cures.
11. A system that forms a wire harness, comprising:
a first mold portion and a second mold portion that define a cavity therebetween, each of the first mold portion and second mold portion is substantially flat in shape for forming a partially-cured wire harness covering having a substantially two-dimensional shape; and
a post-molding fixture that orients the partially-cured wire harness covering in accordance with a predetermined three-dimensional geometry,
wherein the post-molding fixture comprises a base with a plurality guide members that project from the base that orients the wire harness in accordance with the predetermined three-dimensional geometry.
12. The system of claim 11 , wherein the cavity comprises sub-cavities that form a corrugated-like covering of a predetermined thickness that encapsulates the wire harness.
13. The system of claim 12 , wherein a subset of the sub-cavities position the wire harness within each the first mold portion and the second mold portion.
14. The system of claim 11 , further comprising a plurality of leader pins that facilitate alignment of the first mold portion with the second mold portion.
15. The system of claim 11 , further comprising one of interlocking teeth, grooves, slots or channels that facilitate alignment of the first mold portion with the second mold portion.
16. A system of forming a three-dimensional wire harness, comprising:
a two piece mold that defines a cavity therebetween, wherein a combination of a polyol and an isocyanate facilitate a reaction injection molding (RIM) process to form a partially-cured wire harness covering having an intermediate shape;
a means for post-molding that orients the partially-cured wire harness covering from the intermediate shape into a predetermined three-dimensional configuration; and
means for establishing a predetermined cure time based at least in part upon the molding process in view if thickness of the wire harness covering.
17. The system of claim 16 , further comprising means for corrugating the wire harness covering.
18. The system of claim 16 , wherein means for post-molding is a wood, fiberglass, composite, metal, alloy or cardboard fixture.
