Problems solved by technology
At present, the commonly used removal methods are as follows: one is the manual thread removal method, that is, after the injection mold is opened, the injection molded part is removed by hand, and its disadvantages are high labor intensity and low production efficiency; the second is to use the spring top The ejection device, that is, the injection molded part is forcibly ejected by the force of the spring, and its production efficiency is high. Its disadvantage is that the ejection action caused by the change of the spring with the stroke is inconsistent with the axial displacement of the thread ejection, and it is easy to cause radial deformation of the thread and thread turn over

The invention discloses a thread demoulding device of an injection mould. The thread demoulding device comprises a lower mould base, an upper mould base, an ejector plate, a thread mould core, an injection molding part locating and stopping device, a first driving device and a second driving device, wherein the upper mould base is arranged on the lower mould base; the ejector plate is arranged on the upper mould base; the thread mould core is arranged in the upper mould base and the ejector plate; the injection molding part locating and stopping device is arranged on the ejector plate; the first driving device is used for driving the thread mould core to rotate; and the second driving device is used for driving the ejector plate to move upwards. The thread demoulding device disclosed by the invention has the advantages that the original manual thread demoulding way is replaced with a mechanical thread demoulding way, so that the labor intensity is reduced, and the production efficiency is increased; and the thread demoulding device is stable in use and good in using effect.
Description
technical field [0001] The invention relates to a thread-removing device, in particular to a thread-removing device used in an injection mold for releasing a threaded injection molded part. Background technique [0002] The fastest growing mold is the injection mold. Its products are more and more widely used in daily life, such as construction, machinery, electronics, instruments, meters and other industrial fields. After the threaded injection molded part is injected in the injection mold, the threaded injection molded part needs to be ejected. At present, the commonly used removal methods are as follows: one is the manual unthreading method, that is, after the injection mold is opened, the injection molded parts are removed by hand, the disadvantage is that the labor intensity is high and the production efficiency is low; the second is the spring top. The ejection device, that is, the injection molded parts are forcibly ejected by spring force, and its production effici...
