Abstract

The invention discloses a continuous universal plastic injection mold which comprises a base plate. A cylindrical mounting groove is formed in the middle of the side wall of the base plate; a rotary disc is coaxially and rotatably mounted in the mounting groove; a plurality of containing grooves are evenly formed in the side wall of the rotary disc; a lower mold body and an upper mold body which are matched with each other are arranged in each containing groove; and the side wall of each upper mold is provided with a feeding port communicating with an inner mold cavity of the upper mold. According to the continuous universal plastic injection mold provided by the invention, a first permanent magnet plate, a second permanent magnet plate, a third permanent magnet plate and an ejector pin are arranged, and the ejector pin blocks a nozzle in a normal state, so that an injection molding injection pipe and the nozzle can be prevented from being polluted by external impurities; and the ejector pin can be automatically separated from the nozzle for normal injection molding each time, and after injection molding is finished, the ejector pin and the first permanent magnet plate automatically reset to discharge residual raw materials in the nozzle, so that the nozzle can be prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of plastic injection molds, in particular to a continuous general plastic injection mold. Background technique [0002] The traditional plastic injection molding method is mainly to first melt the granular raw material and inject it into the mold cavity, then cool the mold core, and then open the mold to remove the mold core after the mold core is cooled. [0003] However, in actual operation, in order to prevent leakage after each injection, the nozzle of the injection tube is always in contact with the injection port, wait for the mold core to cool and demould, and then inject the raw materials into the cavity again. This method not only has low injection efficiency, but also has While waiting for the mold core to cool, the remaining raw materials at the nozzle of the nozzle will gradually cool down, which will easily block the nozzle, especially for some molds with complex structures, which require longer...
