In the process of ejecting the insert-molding product and the injecting waste material out of the injection mold, The injection mold has at least one product ejector pin used to make the insert-molding product separated from the injecting waste material and then eject the insert-molding product out of the injection mold firstly, and at least one delay ejector pin used to eject the injecting waste material out of the injection mold after the insert-molding product are ejected out of the injection mold. | 08-23-2012 |
20120251656 | INJECTION MOLD - An injection mold for molding a product having a barb at a bottom thereof includes a stationary mold, a movable mold, an ejector pin and a sliding mechanism. The sliding mechanism includes a sliding block mounted on the movable mold, a spring contracted between the sliding block and the movable mold, and a locating element vertically inserted in the spring. A top end of the locating element stretches in the receiving cavity. A corner of the sliding block defines a nick connected for molding the barb. When the injection mold is opened, the sliding block moves upward under the bounce thrust of the spring to make the product parted from the top of the movable mold. An elastic retraction area is accordingly formed between the product and the movable mold for assisting the ejector pins to eject the barb out of the sliding block. | 10-04-2012 |
20130101693 | INJECTION MOLD - 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. | 04-25-2013 |

20120070525 | MOULD WITH REPLACEABLE MOULD CORE - Provided is a mould with flat thimble including a lower mould, a mould core, a plurality of thimbles, an upper mould and an anti-pulling out mechanism. The anti-pulling out mechanism is mounted on the lower and upper moulds, and includes at least one spring locking steel ball, a lower ejector pin, an upper ejector pin and a movable locking pin. The movable locking pin forms a holding recess. The spring locking steel ball is mounted on one side of a core through hole of the mould core. The upper ejector pin is fixed on the upper mould. The movable locking pin is placed in the lower through hole and the core through hole. The present mould can prevent the operator from pulling out the mould core before the molding product being pushed out, so that avoiding damaging the thimble and reducing production cost of the product. | 03-22-2012 |
20120093961 | MOULD HAVING MOVABLE MOLD INSERT - Provided is a mould having movable mold insert, including a male mold, a female mold, a movable mold insert and a mold insert positioning mechanism. The female mold is located just above the male mold and disposes a plurality of core pins. The movable mold insert is movable connected to the male mold. The movable mold insert disposes a plurality of inserting holes corresponding to the core pins. The mold insert positioning mechanism includes a positioning hole and a positioning post matched with the positioning hole. The positioning hole is formed on the movable mold insert, and the positioning post is fixed to the female mold. A protruding length from the bottom surface of the female mold, of the positioning post, is larger than that of the core pins. The mould of the present invention can protect the movable mold insert and greatly improve the product quality. | 04-19-2012 |
20120107446 | PLASTIC INJECTION MOLD - Disclosed is a plastic injection mold, including a stationary mold member and a movable mold member mating with the stationary mold member. An inclined guide pillar and a stop block having a block plan are fixedly disposed on the stationary mold member. A slide having a molding portion is slidably disposed on the movable mold member. A guide pillar hole and an ejector hole are defined in the slide, and a molding cavity is defined by the molding portion with the stationary and the movable mold member. An ejection mechanism disposed on the slide includes an ejector rod and a spring. In a mold release process, a product molded with the mold is initially held by an ejector rod to prevent the product from being deformed when pulled by the slide for ensuring the quality of the molding product. | 05-03-2012 |
