The invention discloses a pulley and a pulley production mold. The pulley comprises an injection molding wheel body, the injection molding wheel body is provided with a drum-shaped rolling surface, the rolling surface is provided with a highest line and a lower line, and a joint line of the injection molding wheel body is arranged at the lower line; the water gap of the injection molding wheel body is arranged on the lower line or the end face of the injection molding wheel body. The pulley production mold comprises a movable mold, the movable mold is provided with a first parting surface and a plurality of first cavities, the side wall of each first cavity is of a drum-shaped structure matched with the rolling surface, and the first parting surface is arranged corresponding to the lower line; the fixed mold is provided with a second parting surface and a plurality of second cavities, the fixed mold is provided with a plurality of feeding ports, the feeding ports are communicated with the second cavities, and the feeding ports are arranged corresponding to the water gaps. Compared with the prior art, according to the scheme, the pulley can be directly used after injection molding is completed, the work of polishing the peripheral face of the pulley to remove a joint line and a water gap is not needed, and therefore the machining procedures can be reduced, the machining cost can be reduced, and the production efficiency of a factory can be improved.
本发明公开了滑轮及滑轮生产模具。滑轮包括注塑轮体，注塑轮体设有呈鼓形的滚动面，滚动面设有最高线和较低线，注塑轮体的合模线设置于较低线；注塑轮体的水口设置于较低线或注塑轮体的端面。滑轮生产模具，滑轮生产模具包括：动模，动模设有第一分型面和若干第一型腔，第一型腔的侧壁呈与滚动面匹配的鼓形结构，第一分型面与较低线对应设置；定模，定模设有第二分型面和若干第二型腔，定模设有若干进料口，进料口与第二型腔连通，进料口与水口对应设置。相对于现有技术，本方案将在滑轮注塑完毕后可直接使用，无需对滑轮的外周面进行打磨去除合模线和水口的工作，从而可减少加工工序，以减少加工成本，并且能提高工厂的生产效率。
