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 |
20080276744 | SIDE CORE-PULLING MECHANISM OF MOLD - A side core-pulling mechanism of mold includes a slide block, an impacted block and a wobbly block. The bottom of the slide block projects outwards to form a columnar pin. The front surface of the impacted block defines a receiving cavity, a first slot and a second slot. The first slot upright extends downwards to pass through the bottom of the impacted block from the over place of the right end of the receiving cavity and communicates with the right end of the receiving cavity. The second slot extends rightwards and downwards to pass through the bottom of the impacted block from a start end of the first slot. The first and second slots communicate with each other. The columnar pin is movable in the first and second slots. The wobbly block is received in the receiving cavity of the impacted block. The wobbly block is against the bottom wall of the receiving cavity to cut off the first slot at a nature status and rotates upwards in the receiving cavity for making the first slot be in a through status. | 11-13-2008 |
20080277822 | APPARATUS AND METHOD FOR PERIODICALLY COOLING INJECTION MOLD - An apparatus for periodically cooling injection mold has a cavity formed between a cavity insert and a core insert of the injection mold. The bottom of the cavity defines a perforation that extends and passes through a lower pushing plate. An ejector pin is received in the perforation. The bottom end of the ejector pin passes out of the lower pushing plate and is above the top surface of a lower fixed plate. A sensor switch that controls several electric valve actuators is located on the lower fixed plate and is below the ejector pin. The electric valve actuators control cooling liquid to flow into several cooling pipes that are configured in the cavity insert and the core insert respectively. A method for periodically cooling injection mold includes the steps of: closing the injection mold and pouring raw materials into the cavity to form a product; pushing the ejector pin downward along the perforation and the bottom of the ejector pin touching and pressing the sensor switch. The sensor switch is inducted, and further causes the electric valve actuators opened. The cooling liquid flows into the cooling pipes for cooling the injection mold. Then, liberate the bottom of the ejector pin away from the sensor switch when the product is taken out from the injection mold. Last, release induction of the sensor switch for causing the electric valve actuator closed correspondingly and for stopping the cooling liquid into the cooling pipes. | 11-13-2008 |
20080292744 | Mold a secondary molding - A mold for a secondary molding includes a lower mold insert, an upper mold insert coupled to the lower mold insert, and an extraction device loaded in the lower mold insert. The lower mold insert has a lower container, a couple of lower notches adjacent to the two opposite sides of the lower container respectively and a lower cavity with two opposite sides connected to the lower notches respectively. The extraction device has an inserting core. The inserting core includes a body with two molding portions at its opposite sides. The body is inserted into the lower container, the molding portions project into the lower cavities. | 11-27-2008 |
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. The connecting head has a gap for encircling the pole and is slidable along the pole and against the block of the pole. | 01-29-2009 |
20090181119 | Lateral core-pulling mechanism of mold - A lateral core-pulling mechanism of mold includes a cavity plate, a cavity insert configured in the cavity plate and defining a shaping recess, and a core-pulling body including a first slide module longitudinally movably disposed in the front of the cavity plate, an angular pin, and two second slide modules movably disposed at two sides of the cavity insert. The first slide module defines an inclined hole, a first shaping core inserted into the shaping recess and two first guide surfaces at two side edges thereof. The angular pin has an inclined block inclining forward and movably received in the inclined hole to drive the first slide module to move forward or backward. The second slide module defines a second shaping core inserted into the shaping recess and a second guide surface slidably matching the corresponding first guide surface to drive the second slide module to move sideward. | 07-16-2009 |
