Title:
ELECTRIC PRECIPITATOR FOR PRESS MOLD AND PRESS MOLD USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/058651
Kind Code:
A1
Abstract:
Provided is an electric precipitator for a press mold which can collect dust generated during press machining more reliably by using electrostatic force, has good installability, and can be used safely. An electric precipitator for a press mold and a press mold using the same, the electric precipitator being used together with a press mold to collect dust generated during press machining with electrostatic force. The electric precipitator is characterized in that: the electric precipitator comprises a multi-layered sheet configured by layering a dust collection layer that holds dust by contact therewith, a first electrode layer, a second electrode layer, an insulating layer, and a tight-fixing layer for installation and fixation on a mold to be used, and a power supply device that applies a voltage between the first and second electrode layers; the insulating layer at least has a first insulating layer that insulates the dust collection layer and the first electrode layer, a second insulating layer that insulates the first electrode layer and the second electrode layer, and a third insulating layer that insulates the second electrode layer and the tight-fixing layer; the first and second electrode layers are films formed by applying a conductive polymer to a polyethylene terephthalate (PET) base and having a surface resistivity of 104 to 105 Ω; and a polyimide film having a base thickness of 75 μm is used as the second insulating layer.
