The invention provides a multidirectional core-pulling type mold, comprising a first mold and a rear mold, wherein a multidirectional core-pulling mechanism is arranged on the rear mold, and comprises a first cylinder, a first slide core, a second slide core and a third slide core; the first cylinder is fixedly connected with the rear mold through a movable block; the initial end of the first slide core is transversely connected to one side of the movable block in a sliding manner; the initial end of the second slide core is transversely connected with the other side of the movable block in a sliding manner; a third slide core is transversely arranged at the tail ends of the first slide core and the second slide core, and connected with a guide mechanism; the third slide core can slide left and right below the first slide core and the second slide core by the guide mechanism. The multidirectional core-pulling type mold provided by the invention is compact in structure, reasonable in design, stable to transmit, stable in core-pulling action, and smooth to demold, a cylinder is adopted as power, the back-off phenomenon is effectively prevented, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a multidirectional core-pulling mold. Background technique [0002] In the prior art, injection molding is a processing method used in mass production of parts with complex shapes, and injection mold is a tool for producing plastic products, which has been widely used. In actual operation, single-phase core-pulling molds cannot meet the diversified needs of existing products, while for multi-directional core-pulling molds, there are generally problems with unstable operation, difficult demoulding, and even crushing of the mold, making Problems such as short mold life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-directional core-pulling mold with stable operation and smooth demoulding. [0004] The invention provides a multi-directional core-pulling mold, which includes a front mold and a rear mold. The rear mold is provided with a multi-directional cor...
