Automobile part injection mold with accelerated ejection mechanism

Abstract

The invention discloses an automobile part injection mold with an accelerated ejection mechanism. The automobile part injection mold comprises an upper mold body, a lower mold body, a first ejector plate and a second ejector plate, wherein the upper mold body is buckled on the lower mold body, an injection molding cavity is formed in the buckling face, an injection molding opening communicating with the injection molding cavity is formed in the upper mold body, a plurality of ejector pin holes are formed in the lower mold body, an upper pin sleeve groove is formed in the outer side of the lower portion of one ejector pin hole, a mold base is arranged below the lower mold body, the four vertex angles of the mold base support and fix the lower mold body through supporting columns, the firstejector plate is arranged between the mold base and the lower mold body and fixedly provided with an ejector pin positioning plate, a lower pin sleeve groove is formed in the position, corresponding to the upper pin sleeve groove formed in the lower mold body, of the first ejector plate, a fixed pin sleeve is arranged in the lower pin sleeve groove, and a movable pin sleeve is sleeved with the fixed pin sleeve in a sliding mode. According to the automobile part injection mold, a gear and the movable pin sleeve with the teeth are designed in an ejection device to complete accelerated lifting ofan ejector pin, so that one side of an injection molding workpiece is lifted quickly, direct discharging is completed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an injection mold for auto parts with an accelerated ejection mechanism. Background technique [0002] Injection molding is a processing method that injects hot-melt plastic material into a closed cavity with the required shape in the mold at high speed, and after the plastic material cools and solidifies, the mold is opened to eject the solidified plastic product to obtain a molded product. Many automobile parts are completed by injection molding. In terms of injection mold design, the mold generally has an ejection mechanism, which lifts the ejector base plate and ejector plate through the ejector rod, and then ejects the product through the ejector pin on the ejector plate. In special cases, some products have complex or special shapes, and only one vertical ejection will cause the product to be ejected, or the product will be deformed due to too fast ejection force, and in...

Problems solved by technology

Many automobile parts are completed by injection molding. In terms of injection mold design, the mold generally has an ejection mechanism, which lifts the ejector base plate and ejector plate through the ejector rod, and then ejects the product through the ejector pin on the ejector plate. In special cases, some products have complex or special shapes, and only one vertical ejection will cause the product to be ejected, or the product will be deformed due to too fast ejection force, and in severe cases, the product assembly will be buckled. Pulling off, making the product need to be repaired or causing the product to be scrapped, thereby reducing the product qualification rate
