Abstract

The invention discloses an ejection mechanism and an injection mold. The ejection mechanism comprises a fixing plate, an ejector pin assembly and a buckling machine assembly; the ejector pin assembly is movably arranged on the fixing plate and is in driving connection with an oil cylinder; the buckling machine assembly is connected with the ejector pin assembly and is used for limiting the ejector pin assembly when the injection mold is opened or closed; when the injection mold is in a mold opening state, under driving of the oil cylinder, the ejector pin assembly is separated from the buckling machine assembly to cut off a water gap of a formed product when the ejector pin assembly is ejected out of the initial position to the first preset position. The ejection structure of the mold is improved, the functions of ejection and automatic cutting of the water gap are achieved, the production efficiency of products is improved, and the production and manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an ejection mechanism and an injection mold. Background technique [0002] In the mold design, the ejector mechanism is an important part of the mold, and its main function is to eject the molded parts in the mold cavity or adhered to the core. In general, the ejector mechanism applies thrust to the fixed plate, and drives one or more ejector pins or thimbles against the formed part through the fixed plate, and ejects the formed part formed in the mold cavity or adhered to the main core. In this way, one molding process is completed and the next molding process is started. In the injection machine, the ejector mechanism is usually installed on the side of the movable mold. Or a molded part adhered to the main core on the male side. [0003] However, the molded parts in the mold cavity are generally connected with nozzles. Generally, after the molded parts are removed, the nozzles...
