Abstract: Mainly for the cooling system has carried on the summary. Put emphasizes on the research and design the cooling system. Including: meaning and purpose of the cooling system, the layout of the cooling water channel, mold temperature, injection molding and products quality, the relationship between the effect of cooling rate on the products production efficiency and improve the relevant calculation method, and cooling system, etc. Cooling system calculation include: the heat released and the volume of cooling water flow rate and cooling water velocity of flow in the pipe, tube wall film heat transfer coefficient between cooling water, cooling pipe in the heat transfer area and number of cooling pipe hole open. The design of injection mould from mould material and structure analysis, step by step in accordance with the purpose of molding parts correctly to complete the design of each part of the mold and molding equipment choice, Including: molding parts, distributary channel, gate, pull rod, demoulding mechanism, the design of the cooling water and the choice of injection molding machine and mold frame. And the die structure of parts of the check, including: check, mould clamping force stroke and the filling high of mold respectively.
Key words: cooling system;the motor seat; injection mould
