Injection upper mould with cooling function and for CPU (Central Processing Unit) fan blade

Abstract

The invention relates to an injection upper mould with the cooling function and for a CPU (Central Processing Unit) fan blade and belongs to the technical field of injection moulds. The injection upper mould comprises an upper mould body; an injection channel is horizontally formed on the left lower portion of the upper mould body; the upper portion of the upper mould body is provided with a heating aluminum block which is used for heating the upper mould body; the upper surface of the upper mould body is downward to form a groove; the lower surface of the heating aluminum block extends downward to form a protruding block which is matched with the groove; a heating chamber which is used for performing steam heating is formed inside the heating aluminum block; the heating aluminum block portion which is located on the left side of the heating chamber is provided with a steam inlet; the heating aluminum block portion which is located on the right side of the heating chamber is provided with a steam outlet; the bottom surface of the heating chamber is an inclined surface, wherein the left portion of the inclined surface is higher than the right portion of the inclined surface; a cooling water chamber is horizontally formed in the heating aluminum block portion which is located below the heating chamber; the inner side wall of the injection channel is provided with a boss which is of an annular structure. According to the injection upper mould with the cooling function and for the CPU fan blade, the structure is simple, the upper mould body is uniformly heated, the heating speed is high, the production efficiency is high, the installation is convenient, and the qualified rate of products is ensured.

Description

technical field [0001] The invention relates to an injection molding upper mold with cooling for CPU fan blades, belonging to the technical field of injection molds. Background technique [0002] At present, in the production of fan blades such as CPUs, the injection molding method is commonly used, and the production efficiency is fast. If the molds usually used are in mass production, their structures are more complicated. When the structure is more complicated, it will bring many problems in the design, such as : 1. The uniformity of heating; 2. The distribution of vent holes; 3. The distribution of feed ports. If the above problems are not handled properly, the qualified rate of the product will be reduced. Contents of the invention [0003] In view of the above problems, the present invention provides a cooling injection molding upper mold for CPU fan blades, which has a simple structure, convenient operation, uniform heating, avoids the influence of uneven heating on...
