Novel electromagnetic die

Abstract

The invention discloses a novel electromagnetic die which comprises an upper die, a lower die, an ejection device and a mode locking device. The upper die is arranged on the upper side of the lower die, the ejection device comprises an electromagnet I, a magnet I, an ejection rod, a switch I and a supporting plate, the mode locking device comprises an electromagnet II, a magnet II, a supporting base and a switch II, the ejection device uses repulsive force generated by the electromagnet I and the magnet I, and the mode locking device uses magnetic force generated by the electromagnet II and the magnet II. The novel electromagnetic die has the beneficial effects that the electromagnetic strong attraction capacity is used, buckling of the upper die and the lower die is achieved, teeth arranged on the upper die and grooves arranged in the lower die are matched, and transverse displacement between the dies is avoided; and through simple mechanical matching, the magnetic force generated bythe electromagnets and the magnets are subject to mutual exclusion, workpieces are ejected out further, deformation and die damage are avoided, the die accuracy is guaranteed, and the production requirement is met.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a novel electromagnetic mold. Background technique [0002] The mold is a very common device in the machinery industry. The existing mold is generally equipped with a fixed mold and a moving mold that is used in conjunction with the fixed mold. When in use, the fixed mold and the moving mold are matched and then produced After the fixed mold and the movable mold are closed, a force needs to be added to the outside, and the fixed mold and the movable mold are locked by this force to prevent the separation of the fixed mold and the movable mold during use. The existing fixed mold and the movable mold The locking force of the moving mold is mainly provided by the mechanical equipment itself. For example, the injection mold provides the clamping force of the mold through the injection molding machine, and the stamping mold uses the clamping force through the press. However, in the actu...

AI Technical Summary

Problems solved by technology

When taking out the workpiece, the slider must be in place and the fixed mold should be inserted into the slider at the same time, and there should not be too large a gap that will cause product burrs, which increases the difficulty of the mold and the processing accuracy of each part

At present, most injection mold ejection devices use ejector pins to eject the mold from the mold groove. Because the ejector pin may deform the top of the mold under a certain pressure, or damage the mold, affecting the accuracy of the mold, so that the production requirements cannot be met.
