20090304845 | Demolding Mechanism of Mold - A demolding mechanism of mold includes a male mold, a swingable block and an elastic element. The male mold defines a receiving groove therein. The swingable block mounted in the receiving groove of the male mold has a pressing arm and a shaping arm connected with the pressing arm. The shaping arm defines a shaping portion for shaping a part of a product to be molded in the mold. The elastic element is resiliently disposed between the bottom of the pressing arm of the swingable block and the male mold for causing the swingable block to swing, which makes the product be disengaged from the shaping portion of the swingable block. | 12-10-2009 |
20090304849 | Injection Mold - An injection mold includes a stationary mold section, a movable mold section and an up-down sliding side core. The movable mold section and the stationary mold section define a molding cavity capable of receiving liquefied molding material for forming an article. The sliding side core is received between the stationary mold section and the movable mold section and adjacent to the molding cavity, a side of the sliding side core defines a fixing portion for engaging and further moving upwardly the expected product out of the molding cavity. The injection mold can mold the expected product and conveniently guide the product out of the mold, the injection mold is easy to be manufactured, the cost for manufacturing the injection mold is lower. | 12-10-2009 |

20080236221 | Slide having a fixing mechanism of a slide insert - A slide having a fixing mechanism of a slide insert includes a slide body, a slide insert and a slide core. The slide body has a connecting portion and an inserting portion. The connecting portion defines a locating hole which stretches through the top surface to bottom surface of the connection portion. The inserting portion defines an inserting hole passing through the front and back surface of the inserting portion. A core hole is defined at the junction of the connecting portion and the inserting portion. The slide insert is located in the inserting hole. One end of the slide insert protrudes around to form a preventing part. The slide core is inserted in the core hole to fix the preventing part between the back surface of the inserting portion and the slide core. Then the slide insert is fixed in the slide. | 10-02-2008 |
20080241304 | Slide having a fixing mechanism of a slide insert - A slide having a fixing mechanism of a slide insert includes a slide body, a slide insert and a slide core. The slide body has a front wall and two sidewalls. The front wall defines a receiving hole. The sidewall defines an inlay cavity. The inlay cavity passes through the receiving hole. The slide insert held in the receiving hole has a moldboard on one end, and on one side it defines a locating opening. The moldboard stretches out of the front wall of the slide body. The slide core is inserted in the inlay cavity of the slide body and further inserted in the locating opening of the slide insert. Then the slide insert is fixed in the slide body. | 10-02-2008 |
20080241310 | Injection mold with a quick-change apparatus - An injection mold with a quick-change apparatus includes a top clamping plate, a cavity plate, a core plate, a core plate frame, an ejector mechanism and a bottom clamping plate. The core insert and the ejector mechanism are defined between the core plate and the core plate frame. A plurality of connecting rods are defined between the core insert and the ejector plates, one end of the connecting rod received in the passageway of the ejector plate, the other end of the connecting rod fixed in the cavity of the core insert to enable the ejector plate and the ejector ret plate to move up and down and connect with the connecting rod all long. So the ejector mechanism and the core insert are connected together, and can be changed together. | 10-02-2008 |
20080248151 | CAVITY INSERT POSITIONING MECHANISM OF AN INJECTION MOLD - A mold insert positioning mechanism of an injection mold includes a top clamping plate, a cavity insert, a restricting bar, multiple screws and a cavity plate fastened on the top clamping plate. The mold cavity is arranged in an approximate central position of the cavity plate so as to form a locating surface, a second back side and a third wall. The accepting space is arranged on the edge of the cavity plate and communicates with the mold cavity so as to form a first front side, a first connecting side, a second front and a connecting side. The second back side urges the cavity insert to move in on the locating surface so as to position the cavity insert once the cavity insert moves in the mold cavity. Multiple screws lock the restricting bar and the cavity plate as an integral so that the cavity insert is positioned in the mold cavity completely. | 10-09-2008 |
20090028983 | Injection mold with a tie bar - The injection mold with a tie bar includes an upper stationary board, a stripping plate, a female board, a male board and a lower stationary plate from top to bottom. The upper stationary plate extends outward to form a projection plate, an accepting hole opened in the projection plate and having a step therein. A tie bar is arranged on the outside of the injection mold and includes a stud, a connecting head and a pole. The stud passes through the accepting hole and is fixed on the top of the pole. The stud is slidable along the accepting hole and against the step. The top of the pole is located the outside of the stripping plate while the bottom extends outward to form at least one block.
