Abstract

PURPOSE:To make it possible to facilitate the finishing of deep groove and to easily form vent hole in the deep groove by a method wherein a plurality of slide core plates, which are divided so as to mold the top surface and the rear surface of each fin of a multistage finned part, are laminated one another so as to be installed in a slide core. CONSTITUTION:Respective slide core plates 22 are laminated in a slide core main body 21 and positioned by knock pins and clampingly fixed by bolts. Each slide core plate 22 is produced by cutting a metal plate having a thickness of 2mm, for example, in the predetermined shape and by working recessed molding surfaces 22b having a depth of 0.5mm, for example, on both its sides by electric discharge machining or the like. In this case, electric discharge machining or polish finishing can be easily performed and the thin parts of a slide core 20 can be finished highly accurately, since the stock is flat plate. The bisected slide cores 20 are slidably set onto a movable mold main body 15. Further, angular pins 6 on fixed side is inserted in inserting holes 23 on both the bisected slide core sides. A molding cavity is surrounded by the respective molding surfaces of a movable side core 14, a movable side liner 13, a sprue bushing 3, a fixed side core 4 and the slide cores 20 at mold closing.

<Effects of the Invention> As explained above, the resin molding mold of the present invention can be used for molding a resin molded product having a multi-stage fin portion in which a plurality of thin-walled portions are arranged in parallel at intervals. In the mold, a slide core for molding the multi-stage fin section is placed inside the mold, and a part of the slide core is divided into multiple slide core plates that mold the top and bottom surfaces of each fin of the multi-stage fin section, respectively. Since the slide core plates are laminated and placed inside the slide core, there is no need to perform substantial deep groove machining while leaving a thin wall part, unlike with conventional slide cores of this type. A slide core with a multi-stage fin-like thin section can be made. Furthermore, since a flat slide core plate is processed, highly accurate processing and finishing can be performed satisfactorily. Therefore,
There is little resistance when removing the molded product during mold release, and damage to the molded product during mold release can be prevented. In addition, by providing very thin grooves on the top or bottom surface of each slide core plate, gas can be easily vented from the deep grooves of the slide core, and molded products may be damaged due to air being trapped when filling the material. Meat etc. can be prevented. Furthermore, if the thin wall part of the slide core is damaged due to use, it can be easily repaired by removing the slide core plate and repairing or replacing it, without having to remanufacture the entire slide core as in the case of conventional methods. can.
