Title: Rotational molding die and production of hollow molded article
Inventor: ONISHI KOJI
IPC: B29L22/00
Filed: 1994-04-08
Abstract: PURPOSE:To form a hollow molded article with a uniform wall thickness by a method wherein the thickness of a mold is specified when a hollow molded article is formed in a rotational molding machine using resin powder or the like. CONSTITUTION:Where a maximum wall thickness of a mold is T1mm and a minimum wall thickness is T2 mm, requirements of 1.2<=T1/T2<=-20 and T2>=1mm are met. A mold is shaped to meet the requirements so that a part where a hollow molded article tends to have a small wall thickness has a large wall thickness and a part where it tends to have a large wall thickness has a large wall thickness, whereby a temperature difference is formed on the inner surface of the mold. As a result, a solid resin layer can be formed on the inner surface of the mold at a uniform speed, and a hollow molded article having a uniform wall thickness can be formed. If T2 is less than 1mm, the mold has a problem in strength, and T2 is determined to 10mm in relation to the weight of the mold. A uniform wall thickness cannot be obtained by a mold having T1/T2 less than 1.2. A mold having T1/T2 more than 20 is difficult to produce.

Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To attempt reduction of heat which is transmitted from the back surface of a carpet to the floor surface, thus escaping to be wasted, by installing a number of dents and protrusions to form an air-layer space on the back surface of the carpet between the back surface and the floor surface. SOLUTION: On the back surface 4 of a carpet, a number of dents and protrusions are installed in order to form an air layer 8 in between with the floor surface 5 where an electric carpet 1 is placed. When the back surface 4 of the carpet is formed, its raw material, felt, is installed, for example, by waling as to have stepwise dents and protrusions in the longitudinal direction. The recessed part of the dents and protrusions installed in such a manner forms an air layer 8 between the carpet back surface 4 and the floor surface 5 and due to the adiabatic effects caused by a holdup of air in the air layer 8, it is possible to reduce the escape of heat which is transmitted from the back surface 4 of the electric carpet 1 to the floor surface 5; thus it can save consumption of electricity.
