Embodiment Construction
[0015] Attached below figure 1 An embodiment of the present invention is described.
[0016] Simplified injection mold structure for slender tubular injection molding parts, with a fixed plate 3 and a moving plate 12 connected to both ends of the machine tool. A main runner 22 is formed, and the inner wall surface of the moving plate 12 is provided with a guide post II 14 and a core 13, and both the guide post II 14 and the core 13 pass through the push plate 11 arranged on the inner side of the moving plate 12, and the guide post II 14 pairs The push plate 11 is positioned and guided and the push plate 11 and the core 13 are in clearance fit. The inner wall surface of the fixed plate 3 is provided with a guide post I9 and the fixed plate 3 is connected to the de-casting plate 4 in the inner wall cavity by a stepped screw I5 One end of the circular die 10 is connected to the fixed plate 8 inside the fixed plate 3 and the mounting plate 7 as a whole, and the other end of the c...

The invention provides a simplified injection mold structure for an elongated tubing injection-molded plastic part. The simplified injection mold structure comprises a fixed flat plate and a movable flat plate which are connected to two ends of a machine tool, wherein a machine tool ejector rod via hole is formed in the movable flat plate; a main runner is formed in the fixed flat plate; a guide column II and a mold core, which pass through a pushing plate on the inner side of the movable flat plate, are arranged on the inner side wall surface of the movable flat plate; a guide column I is arranged on the inner side wall surface of the fixed flat plate; the fixed flat plate is connected with a runner stripper plate in a cavity at the inner wall of the fixed flat plate through a step-shaped screw I; one end of a circular concave mold is integrally connected with a mounting plate and a fixing plate on the inner side of the fixed flat plate while the other end of the circular concave mold is adaptive to the mold core, and a hollow cavity for molding a workpiece is formed between the circular concave mold and the mold core; the hollow cavity is communicated with a branched runner through a feed hole in the circular concave mold, and the branched runner is positioned between the circular concave mold and the runner stripper plate. The simplified injection mold structure has the advantages that the structure is simple, the price, cost and production cycle of a mold are decreased, the processing such as turning, grinding and polishing is easily carried out, the manufacturability is high, and processing and assembling are easy to be carried out.
Description
technical field [0001] The invention belongs to the technical field of injection molds, and in particular relates to a simplified injection mold structure for elongated tubular injection molded parts. Background technique [0002] In the existing textbooks, professional tool materials, and commercial mold base standards, for the design of slender tubes and some push plate type one-mode multi-cavity injection molds, standard structures are generally used or commercial standard mold bases are purchased, and ejector pins, push tubes, The method of pushing the plate ejects the part. The closed height of the mold for this kind of parts is large, which requires a large closed height of the injection molding machine, and the machine tool with a large closed height is required, and the equipment cost is high; the mold structure is complicated and cumbersome to design and manufacture the mold by using a standard structure or purchasing a commercial standard mold base. The price and ...
