Detailed Description
The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 1-2, an injection mold with a rapid stripping device is provided, the stripping device is mounted on a core or a cavity of the injection mold, a mounting hole 1 is processed on a cavity B of an injection mold a, and the stripping device is arranged in the mounting hole; the injection mold comprises a shell 2, an electromagnet 3, a limit ring 4 and a stripper 5, wherein the shell is cylindrical, the electromagnet is arranged at the bottom in the shell, and the limit ring is arranged at the upper part in the shell;
the stripper comprises a permanent magnet plate 510, a sliding rod 520 and a support-off plate 530, wherein the permanent magnet plate and the support-off plate are respectively fixed at two ends of the sliding rod, the permanent magnet plate is arranged above the electromagnet, the sliding rod penetrates through the limiting ring and can slide along the limiting ring, and the support-off plate is exposed out of the shell; when the material is removed, the electromagnet generates a magnetic force repulsive to the permanent magnet plate to push the material remover to move, and the support-removal plate is bounced to force the injection molding piece to be separated from the injection mold. The limiting ring is matched with the permanent magnet plate to prevent the stripper from slipping.
The sliding rod is sleeved with a spring 6, one end of the spring is connected with the limiting ring, the other end of the spring is connected with the permanent magnet plate, and the spring is used for enabling the support-off plate to reset.
The permanent magnet plate material is samarium cobalt magnet or neodymium magnet. The magnetism of the magnet can be reduced or even completely demagnetized along with the rise of the temperature, the temperature of an injection mold is generally above 150 ℃ during injection molding, the stripping column is repeatedly heated in the environment, the magnetism is easily lost, the high temperature resistance of the samarium-cobalt magnet is much better than that of a neodymium magnet, but the price is much higher, the stripping column can be made of a neodymium-magnet iron material with lower cost for injection molding materials with lower temperature requirements of an injection molding process, and otherwise, the samarium-cobalt magnet material is selected.
The electromagnet is electrically connected with a controller 7, and the controller controls the electromagnet to be powered on or powered off.
