Problems solved by technology

The problem is that in the large mold, the length of the slanted ejector rod becomes longer because the slanted top is too small and the mold is too high. Therefore, the strength of the slanted ejector is not enough, which causes the slanted top to bend and break during ejection.

Abstract

The invention discloses an injection mold with a high-strength ejection lifter, and belongs to the technical field of injection molds. The injection mold comprises a movable mold kernel, a movable mold plate, a lifter head, a lifter rod, support blocks and a lower fixing plate, wherein the lifter rod comprises an end ejector rod and a tail ejector rod connected with the end ejector rod; the lifter head is sleeved with an insert; a lifter guiding block is arranged at the bottom of the movable mold plate, the lifter rod is located on the movable mold plate and only fixed and guided by the lifter guiding block, and clearances are reserved between other portions of the lifter rod and the movable mold plate. According to the injection mold, the lifter rod is divided into the end ejector rod and the tail ejector rod, and the diameter of the tail ejector rod is larger than that of the end ejector rod, so that a reasonable movement mechanism of a small part in the large mold is realized, the ejection strength of a lifter ejection mechanism is guaranteed, and the phenomenon that the lifter rod is broken is avoided; material cost is reduced, and the injection mold is simple in structure and convenient to assembly, reduces labor cost and has high market competitiveness.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold with a high-strength ejection inclined top. Background technique [0002] Mold is an indispensable and important tool in injection molding. 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. Since the injection molding processing method has the characteristics of low molding cost, short molding cycle, simple molding process and easy molding of plastic products with complex shapes, it is widely used in the field of plastic product applications. With the continuous development of industry and the continuous introduction of new products, their structures are correspondingly more and more complex. On plastic products, th...
