Description

TECHNICAL FIELD

[0001] The utility model relates to an automobile die technical field especially, relates to a kind of automobile die quick cooling mechanism. BACKGROUND

[0002] In the stamping, injection molding and other production processes of automobile die, the temperature of the die increases due to the heating of high-temperature workpieces. If the temperature of the die is too high, it will not only affect the forming quality of the workpiece, such as causing size deviation, surface defects, etc., but also shorten the service life of the die. Therefore, the quick cooling mechanism can quickly reduce the temperature of the die to ensure the continuity and stability of the production process and improve the product quality and production efficiency.

[0004] As shown in the above literature, in the traditional cooling mechanism, the lower die cavity is generally hollow, and the cooling liquid is injected into the lower die cavity to cool the injection molded part in the lower die through heat transfer. Since the upper part of the lower die needs to be opened and connected with the upper die, only the side and bottom of the injection molded part can be wrapped, and thus only the side and bottom of the injection molded part can be cooled. The upper part of the injection molded part is exposed to the outside for natural cooling, which reduces the overall cooling efficiency. At the same time, the water cooling circulation system is commonly used for automobile die cooling. The key part of the water cooling circulation system is to extract the cooling liquid for heat exchange, so the cooling efficiency is limited by the effect of the heat exchange mechanism. The method is relatively single. Therefore, the present application designs a kind of automobile die quick cooling mechanism which can fully contact with injection molded part and combine two cooling methods. UTILITY MODEL CONTENTS
