Title: Control of thickness for molded product
Inventor: NOMURA AKIHIRO
IPC: B29C48/30
Filed: 1985-07-10
Abstract: PURPOSE:To permit to control easily the thickness distribution in the circumferential direction of molded product such as parison or the like by a method wherein a heating and cooling device is provided on the circumferential direction of the nozzle to control the temperature of circumference of the nozzle upon molding a material. CONSTITUTION:In case of controlling the thickness distribution in the circumferential direction of parison, the outer peripheral rim section of lower end of a mandrel 1 and the outer peripheral section of lower end of the main body 5 of nozzle are heated or cooled locally by the heating and cooling devices 6, 7. When the circumferential thickness of the parison is (t1) at right side and (t2) at left side, for example, and (t1)>(t2), only the right sides of the outer circumferential rim of lower end of the mandrel 1 and the outer circumferential section of lower end of the main body 5 of nozzle are cooled locally by the heating and cooling device 6, 7. When one part of the nozzle is cooled in such manner, the swell of the cooled section is enlarged while nozzle gap G is kept in constant in the circumferential direction, therefore, the thickness of the parison 8 becomes thick in this part locally. Accordingly, the thickness distribution in the circumferential direction of the parison 8 may be controlled properly by heating or cooling a necessary position in the circumferential direction of the nozzle properly.

Abstract: PURPOSE:To facilitate wire connecting and improve reliability by making a jet nozzle movable in the axial direction with respect to an upper wire electrode guide and increasing the distance toward a nozzle outlet at the time of connecting a wire electrode while reducing the distance at the time of electric discharge machining. CONSTITUTION:At the time of connecting a wire electrode, as a jet water column forming liquid 11 which can overcome a compression spring 25 is made flow, a jet nozzle 12a is depressed by receiving liquid pressure on the top face of a flange 24 and the inner bottom face of the nozzle increasing the distance L between an upper diamond die 5 and a nozzle outlet 13.
