Embodiment Construction
[0029] refer to Figure 1 to Figure 9 , a three-opening hook-type mold opening and closing mechanism for an injection mold of the present invention, including a cavity plate lockway 1, a panel hook 2, and a core plate hook 3. Based on the description of the application mold, the side facing the mold is the inner side, and the side facing the mold The outer side is the outer side, wherein: the inner side of the cavity plate lockway 1 is a rectangular block-shaped base, and the outer side is provided with a protruding rectangular door frame-shaped steel door frame in the center of the base. Components; the outer surface of the base of the cavity panel lockway to the inner wall size of the door frame crossbeam, which is slidingly matched with the thickness of the B step 22 of the panel hook 2; the spacing dimension of the inner wall of the door frame two sides of the cavity panel lockway, and the The overall width of the core board hook 3 is slidably matched; on the base of the c...

The invention discloses a three-opening hooked opening / closing mould mechanism for an injection mould. The three-opening hooked opening / closing mould mechanism for the injection mould comprises a cavity plate locking channel (1), a panel hook (2) and a core plate hook (3). In the three-opening hooked opening / closing mould mechanism for the injection mould, a stationary mould cavity plate is provided with the cavity plate locking channel; the panel hook is arranged on a stationary mould panel; the core plate hook is arranged on a moveable mould core plate; and the stationary mould panel, the stationary mould cavity plate and the moveable mould core plate are connected with one another to form a three-opening series-wound structure according to a mould opening / closing program, so that the problems of high comprehensive cost and low production efficiency in the prior art are solved. In the three-opening hooked opening / closing mould mechanism for the injection mould provided by the invention, a mechanical linkage core-pulling mechanism can be arranged in the stationary mould panel and the stationary mould cavity plate to perform core pulling; and the mould opening / closing program actions of stationary mould core pulling, mould opening of the moveable mould and the stationary mould, mould closing of the moveable mould and the stationary mould and stationary mould core block resetting are integrated through the mould opening / closing action of an injection machine, so the injection mould which needs the stationary mould to perform core pulling firstly fulfills the aims of reducing the comprehensive cost and improving the production efficiency.
Description
technical field [0001] The invention relates to a mold opening mechanism of an injection mold, in particular to a three-opening hook-type mold opening and closing mechanism applied to an injection mold whose injection mold needs to be fixed and core-pulled first. Background technique [0002] In the prior art, for injection molds that need to be core-pulled first for fixed molds, refer to Figure 10 , using a hydraulic cylinder core-pulling mechanism on the fixed mold to pull the core; before the mold is opened, the core-pulling slider set in the fixed mold cavity must be pulled out by the oil cylinder, and then the movable and fixed molds of the mold are allowed to open the mold; When the mold is closed, the movable and fixed molds must be closed first, and then the oil cylinder pushes the core-pulling slider to reset; otherwise, the moving mold core, the core-pulling slider of the fixed mold, and the finished product will be damaged. The core-pulling mechanism of the oil c...
