Embodiment Construction

[0030] Such as figure 1 The first embodiment of the partitioned temperature-controlled roller for microstructure replication of the present invention shown has a cylinder body 1 and an end cap 2, and the end cap 2 is clearance fit with the cylinder body 1 for partitioning of microstructure replication The circumference of the temperature-controlled roller is divided into two or more regions. In order to make the surface temperature change of the temperature-controlled roller body 1 of the partitioned temperature-controlled roller for microstructure replication better match the product process requirements, the size of each region is different. . There is one or more cylinder heating devices for heating the cylinder in at least one area, and the surface temperature of the cylinder 1 in different areas is different; the partition temperature control for microstructure replication The roller also has a cylinder driving mechanism 4 that drives the cylinder 1 to rotate around the ...

Abstract

The invention relates to a zoning temperature control drum for microstructure replication, provided with a drum body and an end cover. The circumference of the zoning temperature control drum for microstructure replication is divided into two or more zones, the drum body in at least one zones is provided with one or more drum heating devices for heating the drum body in the zone, and the drum body has different surface temperatures in different zones. The zoning temperature control drum for the microstructure replication is also provided with a drum body driving mechanism for driving the drumbody to rotate around a central line of the drum body, and the drum body heating device does not rotate relative to the central line of the drum body. The zoning temperature control drum for the microstructure replication can be used to produce accurate-shape sheets with microstructures, increase the cooling speed of the material and shortening the production cycle.

Description

technical field [0001] The invention relates to a hot pressing roller, in particular to a partitioned temperature-controlled roller for microstructure replication. Background technique [0002] The micro-structured components of micro-manufacturing technology are gradually widely used in various high-tech products such as optoelectronics, micro-electromechanical, and optical communications. Through the cooperation and development of high-precision molds and forming technologies, a large number of micro-structured shapes can be replicated Products with micro-structured surfaces generally use molds with fine structures for injection molding, while products with large size and continuity generally require roll replication molding by extrusion calendering. [0003] In order to fully reproduce the fine structure of the mold, microstructure injection molding generally uses two methods to achieve it. 1. Adopt high-speed injection to reduce the flow time of raw materials, reduce the...
