Abstract
An injection mold for molding a product which has an inclined groove and a straight gap at a side thereof includes a female mold and a male mold. The female mold includes a female core and an inclined pillar mounted in the female mold. The male mold includes a male core, a first sliding block and a second sliding block. The first sliding block is slidably mounted on the male mold, and has an inclined guiding surface. The second sliding block is slidably mounted on the inclined guiding surface. When the injection mold is opened, the second sliding block is smoothly parted from the product along the inclined guiding surface to form the inclined groove, and then, the first sliding block is parted from the product to form the straight gap under the action of the inclined pillar.
