  • Patent number: 8529244
    Abstract: An injection mold for molding a product having at least one bar formed at one side thereof. The injection mold includes a stationary mold including an inclined pillar and a movable mold including a movable core and a sliding block mounted on a top thereof. The inclined pillar inserted in the sliding block to drive the sliding block to slide towards or away from the movable core. A shaping cavity for molding the product is formed among the movable core, the sliding block and the stationary mold. The end surface of the sliding block further defines at least one shaping groove connected with the shaping cavity for molding the bar. The movable mold further includes an ejector pin and a maintaining pillar. The maintaining pillar resists against a bottom of the sliding block to avoid the ejector pin moving upward before the bar completely parted from the shaping groove.

  • Publication number: 20120141624
    Abstract: Disclosed is a shaping mold for products with a circular hole, comprising a male mold and a female mold corresponding thereto, forming a core cavity therebetween after the shaping mold is closed. A pin mold core and a female mold core capable of dipping into the core cavity are in the male mold and female mold respectively. A mating face of the pin mold core and the inner face of a square hole shaping portion of the female mold core compress with each other after the shaping mold is closed. With the limitation head and the limitation boards buckling up, the shaping mold of the present invention restricts the pin mold core not rotated in the core cavity to prevent dislocation of the mating face and the square hole shaping portion happening during the insert and shut off operation. Accordingly, the shaping accuracy of the products can be guaranteed.
