A linear slide over-molding fabrication method for producing a linear slide by putting a metal base onto a core in an injection mold and filling a molten plastic in the injection mold to mold guide structures on the metal base for guiding cylindrical rolling elements. The metal base has a track groove for matching with a linear guideway, guide structure attachment portions at two opposite sides of the track groove, and first joint surfaces at two opposite sides relative to the guide structure attachment portions. The core has guide structure forming portions corresponding to the guide structure attachment portions, second joint surfaces respectively facing toward the first joint surfaces with a gap about 0.02 mm˜0.04 mm therebetween. Thus, the applied engineering plastic material can fill up the guide structure forming portions to form a plurality of guide structures on the two opposite sidewalls of the track groove.
A linear slide over-molding fabrication method, comprising:
A linear slide, comprising a linear slide metal base, said linear slide metal base comprising a straight track groove located in a bottom side in communication between opposing front and rear sides thereof for mating with a linear guideway, three guide structure attachment portions located in said bottom side at each of two opposite sidewalls of said straight track groove in a parallel relationship and in communication between said opposing front and rear sides of said linear slide metal base, a load track defined between each two adjacent said guide structure attachment portions, a plurality of first joint surfaces located in said bottom side at each of said two opposite sidewalls of said straight track groove and at two opposite sides relative to the respective said three guide structure attachment portions and in communication between said opposing front and rear sides thereof, a plurality of back-flow holes respectively disposed in two opposite sidewalls thereof in communication between the opposing front and rear sides thereof and a plurality of sink holes respectively located in the opposing front and rear sides thereof and abutting opposing ends of said back-flow holes, a plurality of guide structures respectively molded on said guide structure attachment portions at the two opposite sidewalls of said straight track groove adapted for guiding cylindrical rolling elements of a chain belt, a non-load track and a back-flow guide structure molded in each said back-flow hole, a plurality of mounting bore columns molded on the opposing front and rear sides of said linear slide metal base and respectively partially embedded in said sink holes for the mounting of a circulator at each of the opposing front and rear sides of said linear slide metal base, a plurality of through holes located in said linear slide metal base, and a plurality of anchoring structures,
