Abstract

The invention discloses an injection mold. The injection mold comprises a movable mold and a fixed mold combined with the movable mold, wherein the movable mold comprises a movable template, a movable mold core located on one side, which is arranged towards the fixed mold, of the movable template, inclined ejection heads located on one side, which is arranged towards the fixed mold, of the movable template, a guide structure fixed between the movable mold core and the inclined ejection heads, and driving pieces fixedly connected with the movable template; the movable mold core comprises a fixed surface which is arranged towards the movable template and is combined with the movable template, a movable forming surface opposite to the fixed surface, and a peripheral side surface connected between the edge of the movable forming surface and the edge of the fixed surface; the inclined ejection heads are movably and convexly arranged on the peripheral side surface of the movable mold core through the guide structure; and the driving pieces are connected with the inclined ejection heads so that the inclined ejection heads are driven to move along a guide direction of the guide structure. The injection mold disclosed by the invention has the effect that an inclined injection structure is stable.

Description

technical field [0001] The invention relates to the field of molds, in particular to injection molds. Background technique [0002] Please see figure 1 , The injection mold includes a movable template 10, a fixed template (not shown), and a movable core 20 and a fixed mold core (not shown) between the movable template 10 and the fixed template. Wherein, the movable mold core 20 is fixed on the movable template 10, and the fixed mold core is fixed on the fixed template. When the movable platen 10 moved close to the fixed platen, the movable mold core 20 was closed with the fixed mold core to form the product; when the movable platen 10 moved away from the fixed platen, the movable mold core 20 and the fixed mold core were opened so that out products. For the undercut of the injection molded product, the injection mold also includes a needle plate 30 and an inclined top 40 . A movable space is provided between the movable mold core 20 and the movable template 10, and the n...
