Abstract

PURPOSE:To be able to cast a resin raw material in a preset amount and under a predetermined condition by a method in which an expansible resin raw material is cast into molds being fed from an injection means having a specific synchronous motor, a differential gear, etc., and moving toward the feeding direction. CONSTITUTION:The moving mechanism of an injector 30 to cast an expansible resin into molds 11 being fed by a feeding means 13 in accordance with a predetermined manner 12 is made up of a feed motor 34 attached to the fixing base 21 of a machine base 20, a synchronous motor 35, a differential gear mechanism 36, a screw 37 connected wit the gear mechanism 36, and a moving base holder 38 with a threading part with the screw 37. When a variation occurs in the speed of a conveyer 13 moving at a given speed, the revolving number of the synchronous motor 35 is changed and thereby the turning output of the differential gear mechanism 36 is changed.
