Design of the hot-melt molding working-platform

Abstract：The hot-melt molding working-platform is an automated equipment, which uses the advanced technology of hot-melt to process some special raw materials, that combines machinery, electronics and electricity. The equipment is mainly composed of three different devices, which are called moving part, pressing part and electrical-heating part respectively.The moving part is driven by single-acting cylinder and guided by standard guide rail to transport the raw part to the fixed location. Then the product is melted and molded by the electrical-heating device driven by the pressing cylinder. Thereafter, the finished product is transported back and the above process is repeated. This equipment can circulate the motions of automated material delivery and automated melting and molding so that it improve the working efficiency and decrease the working intensity to a large extent. And we could process various products by changing the mould.

This paper analyzes the working principle and main parameters and carries out the main design plan for the whole equipment, which includes the main material selection, structure analyses and basic calculations.
