An automotive regulator mold assembly with a reverse top mechanism

Abstract

The invention discloses an automobile adjuster mold assembly with reverse-ejecting mechanisms. The automobile adjuster mold assembly comprises an upper movable mold and a lower fixed mold, the interiors of the upper movable mold and the lower fixed mold are provided with the reverse-ejecting mechanisms through mounting layers respectively, wherein each mounting layer comprises a cylindrical sliding groove, a rectangular stop-rotating groove, a cylindrical rod groove and an ejecting block groove; and each reverse-ejecting mechanism comprises a cylindrical magnetic sliding block, a rectangular transmission rod, a hollow ejector rod and an ejecting block, wherein an electromagnetic seat is arranged at the bottom end of the cylindrical magnetic sliding block. A forming product is easily separated from a mold cavity under the thrust action of high-pressure gas, so that the integrity and the quality of the ejection forming product are guaranteed, energy is saved, and the ejection efficiencyis improved; and the reverse-ejecting mechanisms are enabled to eject the forming product through the two driving modes of the magnetic field force effect of the electromagnetic seat and the gas pressure action of a piston type air pump correspondingly, the diversity of the driving mode improves the error-tolerant rate of the reverse-ejecting mechanisms, so that the service life of the reverse-ejecting mechanisms is longer, the ejecting block can return to an initial position every time correspondingly, and a groove or a defect cannot be generated on a produced adjuster outer shell either.

Description

technical field [0001] The invention relates to the field of automobile molds, in particular to an automobile regulator mold assembly with an anti-jacking mechanism. Background technique [0002] The car regulator is composed of three relays, one is responsible for adjusting the output voltage of the generator, it connects the magnetic field excitation of the generator to different circuits through the relay contact connection and separation, so as to control the excitation current of the generator and realize the The purpose of stabilizing the output voltage of the generator; one is responsible for preventing the charging current from being too large. When the charging current is too large, the circuit will make the voltage regulation relay and the current limiting relay act simultaneously, disconnect the excitation circuit of the generator, and stop the generator from working; one It is responsible for cutting off the charging circuit when reverse current occurs, and the r...

Problems solved by technology

[0005] (1) The driving mode of the ejector mechanism is single, and most of them use the cylinder to drive the ejector pin to eject the formed product. Therefore, once the oil cylinder is damaged or other parts are damaged, it must be repaired in time, which will delay the production efficiency of the ejector mechanism;

[0006] (2) The ejector rod of the mold ejector mechanism returns to its original position mostly by the elastic restoring force of the spring, but the spring will decrease in elasticity after being used for a long time, so that the ejector rod cannot return to its original position in time, which not only affects production Efficiency, and because the ejector pin cannot return to its original position and the top protrudes in the mold cavity, a groove will be formed after the product in the mold is formed, thus affecting the production quality of the automobile regulator shell;

[0007] (3) Most of the ejector mechanisms rely on the ejector pin to eject the molded product, but when the product is formed, its outer side is often adhered to the inner cavity of the mold. If the ejector force is too large, it is easy to damage the adhesive part and cause It affects the product quality, so the product must be ejected slowly, so the ejection efficiency is low, and the ejector pin has to overcome the adhesion force between the product and the mold to do work, so the driving requirements of the ejection mechanism are high and consume a lot of energy
