Push-out device

Abstract

The invention discloses a push-out device, which comprises a lower mold base, an upper mold base, a top plate and a drive device, wherein the upper mold base is arranged on the lower mold base; the top plate is arranged on the upper mold base; the drive device is used for driving the top plate to move upwards, and comprises a motor, a worm, a worm gear, a gear, a rack, a push rod plate and push rods; the worm is arranged on an output shaft of the motor, and is matched with the worm gear; the gear is arranged at the inner end of the worm gear, and is matched with the rack; the rack is connected with the push rod plate; a plurality of push rods are arranged on the push rod plate; and the top of each push rod contacts the top plate. According to the push-out device disclosed by the invention, manual taking of injection molding parts in the past is replaced with mechanical pushing of the injection molding parts, so that the labor intensity is reduced and the production efficiency is improved; the use effect is good; the production cost is reduced; and the production efficiency is also improved.

Description

technical field [0001] The invention relates to a push-out device, in particular to a push-out device used in injection molds for pushing out injection molded parts. 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 injection molded part is finished injection molding in the injection mold, the injection molded part needs to be taken out. At present, the commonly used removal methods are as follows: one is manual removal, 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 to use a spring ejection device , That is, the injection molded parts are ejected by the spring force, and its production efficiency is high. The disadvantage is that the sp...

At present, the commonly used removal methods are as follows: one is manual removal, 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 to use a spring ejection device , that is, the injection molded parts are ejected by the spring force, and its production efficiency is high. The disadvantage is that the spring force is difficult to control and the stability is poor, which makes it difficult to control the axial displacement of the injection molded parts, and the spring needs to be replaced frequently, which increases the production cost.
