Baffle pipe and core-cooling device for an injection mold

Abstract

The present invention relates to a core-cooling device for an injection mold which molds plastic injection-molded articles. More particularly, the present invention relates to a core-cooling device for an injection mold, wherein cooling water is efficiently supplied to circulate through a cooling water channel of a core and thus uniformly and quickly cool the core. The core-cooling device for an injection mold according to the present invention comprises: a basic cooling water pipe which is formed on a lower disk (20) and which includes a cooling water inlet (110) and a cooling water outlet (120); and core-cooling water pipes (200) in communication with the cooling water inlet (100) and the cooling water outlet (120) of the basic cooling water pipe so as to enable cooling water to circulate through the interior of a lower core (30).; Baffle pipes (210) divided into left and right sections are coupled to respective core-cooling water pipes (200). The cooling water inlet (110) of the basic cooling water pipe enables cooling water to be simultaneously fed into each of the core-cooling water pipes (200) via distribution pipes (111) connected to the lower ends of baffle pipes (210), respectively. The cooling water outlet (120) of the basic cooling water pipe is connected to lower portions of the core-cooling water pipes (200) so as to discharge, to the outside from the core-cooling device, the cooling water which is fed through the lower ends of the baffle pipes (210), discharged from upper portions of the core-cooling water pipes (200), and falling down toward the lower portions of the core-cooling water pipes (200) in order to cool the lower core (30).

Description

technical field [0001] The invention relates to an injection mold core cooling device for molding plastic injection moldings, in particular to a baffle tube and a mold core cooling device, which can effectively supply cooling water circulating along a cooling water path of the core, This enables rapid and uniform cooling of the core. Background technique [0002] Generally speaking, molds include: injection molds for producing plastic products, stamping molds for making products from iron plates, and die-casting molds for melting metals to make products like plastic products. [0003] Among them, the injection mold is to fill the high-temperature molten material into each mold through high pressure, so as to produce corresponding plastic products according to the internal shape of the mold. It roughly includes the following processes: raw material input process, drying process, injection molding machine raw material Input process, injection molding process, product removal ...

Problems solved by technology

[0013] Second, since the cooling efficiency of the cooling water decreases during circulation, the problem of uneven temperature between one side of the lower core 30 and the other side occurs
