Problems solved by technology

The ejection process of the existing ejection mechanism is generally carried out at a constant speed along with the mold opening process of the movable mold, the ejection effect is easily affected by the stroke of the movable mold, and the ejection effect is not good
In addition, since the ejector rod is prone to friction with the movable mold during the ejection process, the movement resistance is increased, the contact parts are easily worn, the life of the equipment is reduced, and the production and maintenance costs are increased.
Third, improper or offset position of the ejector rod may cause damage to the product

Abstract

The invention provides an injection mold. The injection mold comprises a fixed mold, a movable mold, a top plate, a fixed mold core and a movable mold core, wherein the top plate and the fixed mold are relatively fixed; core pulling sliding blocks are fixed inside the top plate; the core pulling sliding blocks are connected with cylinders; the inner sides of the core pulling sliding blocks are inclined planes; at least one ejector rod is arranged on each inclined plane; and ejection channels for allowing the ejector rods to perform reciprocating motion in the vertical direction are arranged inside the fixed mold and the movable mold. According to the injection mold, a product can be stably demolded more quickly.

Description

technical field [0001] The invention creates the technical field of mold processing and manufacturing, and in particular relates to an injection mold for cylinder core pulling and ejection. Background technique [0002] After the injection molding of the mold is completed, it is generally necessary to use an ejector mechanism including an ejector rod to eject the formed product during the mold opening process, so that the product can be completely separated from the mold. The ejection process of the existing ejection mechanism is generally carried out at a constant speed along with the mold opening process of the movable mold, the ejection effect is easily affected by the stroke of the movable mold, and the ejection effect is not good. In addition, since the ejector rod is prone to friction with the movable mold during the ejection process, the motion resistance is increased, the contact parts are easily worn, the service life of the equipment is reduced, and the production ...
