AI Technical Summary

Technical Problem

The poor cooling efficiency of polyurethane foam in the mold cavity leads to excessively long molding and processing time, reducing work efficiency.

Method used

A rapid prototyping device was designed, which includes a water flow channel, an inlet pipe, an outlet pipe, a metal partition, and a cooling fan. It accelerates the cooling and molding of the foam material inside the mold cavity by combining cooling water and air cooling, uses the metal partition to absorb and conduct heat, and achieves automated material feeding through electric push rods and movable ejector rods.

Benefits of technology

It significantly improves the cooling and molding rate of foamed materials, reduces production time, increases production efficiency, and provides a convenient automated feeding process.

Abstract

This utility model discloses a rapid prototyping device for thermoplastic polyurethane microporous foam elastomer. A fixed mold base is fixedly installed at one end of the top of the base. An extrusion port is opened in the middle of one end of the fixed mold base. Hydraulic telescopic rods are symmetrically fixedly installed at the top end of the base away from the fixed mold base. A movable mold base is fixedly connected between the ends of the two hydraulic telescopic rods. A mold cavity is opened in the middle of one end of the movable mold base. A water flow channel is opened inside the movable mold base at the position corresponding to the mold cavity. A water inlet pipe is fixedly connected to one end of the water flow channel, and a water outlet pipe is fixedly connected to the other end of the water flow channel. This utility model achieves simultaneous heat dissipation through two different methods, which accelerates the heat dissipation process, increases the cooling and molding rate of the foam material, reduces the time required for overall molding, effectively improves production efficiency, and provides great convenience for workers to handle and collect the material after sufficient cooling and heat dissipation.
