Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] like figure 1 In the shown embodiment, a mold cooling system includes a core holder 2 and a core 1 embedded in the core holder. For the convenience of processing and manufacturing, the core is usually fixed on the core holder. The base part 11 and the protruding part 12 for forming are formed, and an upper concave cavity 13 is set on the bottom surface where the base part of the core fits with the core holder, and the lower cavity is provided at the position corresponding to the upper cavity of the core holder. 21. A cluster cooling seat 3 extending to the bottom surface of the lower cavity is embedded in the upper cavity, that is to say, the cluster cooling seat is fitted in a closed cavity formed by the upper and lower cavity. The cooling core of the present invention adopts a cooling well structure, which is different from the existi...

Abstract

The invention discloses a mold cooling system, which comprises a mold core fixation seat and a mold core embedded on the mold core fixation seat, wherein the bottom surface of attaching of the mold core and the mold core fixation seat is provided with an upper concave cavity, the mold core fixation seat position corresponding to the upper concave cavity is provided with a lower concave cavity, a cluster cooling seat extending to the bottom surface of the lower concave cavity is embedded inside the upper concave cavity, a column-shaped upper cooling well is arranged inside the mold core, the cluster cooling seat position corresponding to the upper cooling well is provided with a lower cooling well, the bottom surface of the lower cooling well is provided with a cooling pipe extending to the upper cooling well, water flowing channels are arranged between the cooling pipe and the upper cooling well, and the cooling pipe and the lower cooling well, a water inlet pipeline for communicating a cooling pipe inner hole and a water outlet pipeline for communicating the lower cooling well are arranged inside the cluster cooling seat, and a cooling water sealing structure is arranged between the mold core and the cluster cooling seat and is positioned on the docking position of the upper cooling well and the lower cooling well. According to the present invention, when the mold cooling system is used for cooling a mold core, a cooling temperature can remain uniform, a cooling effect is good, and arrangement of the cooling water pipeline is convenient.

Description

technical field [0001] The invention relates to a structure of a molding die, in particular to a cooling system of the die. [0002] Background technique [0003] In molding molds such as die-casting molds and plastic thermoforming molds, a cooling system is usually required to keep the mold at a suitable temperature by cooling the cavity (concave mold) and core (convex mold) of the mold, so that It is beneficial to ensure the quality of molded products and improve the efficiency of mold molding. There are two types of common structures in the existing mold cooling system. One is used to cool the cavity. Usually, a straight-through cooling pipeline is arranged on the die near the cavity, and cooling water circulates in the cooling pipeline so as to The other type is used to cool the core, usually a cylindrical cooling well is set in the core, and a partition is set in the cooling well to form two connected cooling cavities, and the cooling water flows from the cooling pipe...
