Design the injection mould of the support block
Abstract
This design is plastic injection mold design, plastic injection mold molding plastics is for Switching power supply Case, The design contents are parts of technology establishment：technology Analysis of part，The computation of volume and quality of part，Injection machine parameter is determined；structural design：the choice of parting surface，the determine of cavity number，the design of the gate and the core-pulling mechanism，calculating the size Cores cavity；the calculation mould heating and cooling system，The mold closed highly determined；Injection machine related parameter examination.
Plastics has the smaller dimension, use a two-cavity, single parting surface injection structure，choose the parting surface in plastic parts on the biggest section level umbriferous, use push structure，running calmly and safely, Launched in plastic parts won't leave ejection trace, due to the plastics side has holes, so we must adopt slanted-guide-pillar core-pulling mechanism.
The design of such a structure can be used to ensure reliable Die work to ensure that the other parts of the tie. Finally has carried on the examination to the mold structure and the injection machine match.
Key word: injection moulding；Switching Power Supply Case；the structural design；Computer - Aided Design
