SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the problem that above-mentioned prior art exists, provide a chain belt mold processing, this mould can put into the chain belt with the ball when processing the chain belt, has reduced a large amount of manpower and materials, and the clearance between ball and chain belt is little, and the degree of cooperation is high, and the slider that adopts this chain belt removes smoothly and the security is high.
The utility model provides a technical scheme that its technical problem adopted: the chain belt processing mold comprises an upper mold and a lower mold, wherein a runner groove surrounding the plane of the upper end of the lower mold for a circle is formed in the upper end of the lower mold, a middle runner connected with the left end and the right end of the runner groove is formed in the upper end of the lower mold, a plurality of injection molding grooves formed in the upper end of the lower mold are formed in the front end and the rear end of the middle runner, fixing groove grooves are formed in the front side and the rear side of the upper end of the injection molding grooves, a plurality of ball grooves distributed uniformly are formed in the inner sides of the injection molding grooves, ejector part holes are formed in the bottoms of the ball grooves at intervals, a plurality of first runners connected with the middle runner are formed in the outer sides of the injection molding grooves, a plurality of second runners connected with the runner groove are formed in the front side and the rear side of the injection molding grooves, the runner groove is formed in the upper side of the front end of the lower mold, and machining errors of the ball and the chain belt are eliminated.
For further improvement, the upper die structure and the lower die structure are symmetrically arranged.
Further perfect, open the lower mould front end left and right sides has first cooling hole, the lower mould left end is opened around both sides and is opened the second cooling hole that has with first cooling hole connection, conveniently cools off the lid mould fast, increases the practical life of mould.
Further perfection, a plurality of guide grooves located on the outer side of the runner groove are formed in the periphery of the upper end of the lower die, and errors are avoided when the upper die and the lower die are assembled.
Further perfection, all be equipped with round chamfer on the upper end of lower mould all around and runner groove cell wall, it is good to operating personnel's protectiveness, also can be better protection shaping good mould.
The utility model discloses profitable effect is: the utility model has the advantages of reasonable design, be equipped with the ball groove for ball and chain belt integrated into one piece have reduced the time of assembling the ball, also make the clearance between ball and the chain belt littleer, have eliminated the machining error of ball and chain belt, make this chain belt slide when using smoothly and steadily.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
referring to figures 1-4: the chain belt processing mold in the embodiment comprises an upper mold and a lower mold 69, wherein the upper end of the lower mold 69 is provided with a runner groove 70 which surrounds the periphery of the upper end plane of the lower mold 69, the upper end of the lower mold 69 is provided with a middle runner 71 which is connected with the left end and the right end of the runner groove 70, the front end and the rear end of the middle runner 71 are provided with a plurality of injection molding grooves 72 which are arranged at the upper end of the lower mold 69, the front side and the rear side of the upper end of each injection molding groove 72 are provided with fixing belt grooves 82, the inner side of each injection molding groove 72 is provided with a plurality of ball grooves 73 which are uniformly distributed, the bottoms of the ball grooves 73 are provided with ejector holes 74 at intervals, the outer side of the middle injection molding groove 72 is provided with a plurality of first runners 75 which are connected with the middle runner 71, the outer side of the front injection molding groove 72 and the rear groove is provided with a plurality of, the left side and the right side of the front end of the lower die 69 are provided with first cooling holes 79, the left end of the lower die 69 is provided with second cooling holes 80 which are connected with the first cooling holes 79 and are arranged on the front side and the rear side, the periphery of the upper end of the lower die 69 is provided with a plurality of guide grooves 78 which are positioned on the outer side of the runner groove 70, and the periphery of the upper end of the lower die and the wall of the runner groove are provided with round chamfers 81.
