The invention discloses a double-rod inclined ejection core-pulling mechanism. The double-rod inclined ejection core-pulling mechanism comprises an upper compound plate and a lower compound plate, the upper compound plate and the lower compound plate are used for supporting the whole mechanism, a mold core is arranged in the lower compound plate, a mold core insert is arranged in the mold core, an ejector pin plate is arranged between the lower compound plate and the mold core, the double-rod inclined ejection core-pulling mechanism is characterized by further comprising a double-rod ejection assembly, the double-rod ejection assembly is arranged on the ejector pin plate, and the double-rod ejection assembly comprises a vertical ejection rod which is used for ejecting an injection molding part, an inclined ejection rod which is used for demolding an undercut product and an inclined ejection assembly which is used for controlling the inclined ejection of the inclined ejection rod. The invention provides the double-rod inclined ejection core-pulling mechanism, while demolding of the undercut product is achieved, the mold structure is simplified, the mold manufacturing cost is reduced, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a core-pulling mechanism of an injection mold, in particular to a double-rod inclined top core-pulling mechanism. Background technique [0002] Due to the needs of assembly, some plastic parts usually enlarge the installation hole or pit and groove angle, so it is not possible to directly design the inclined roof or slider according to the traditional method. Usually we do core-pulling or core-small mold opening. Core-pulling needs to use an oil cylinder to drive the core-pulling slider, and follow the product’s back-drawing angle to break away from the undercut to make the product separate, while small mold opening needs to use external hooks and built-in springs. The core and the core backing plate are opened for a certain distance to make the product out of the undercut, so as to complete the product ejection and pick-up. The disadvantages of this type of structure are: 1. The use of an oil cylinder to pull the core will in...
