  • Patent number: 4657519
    Abstract: In manufacturing a toy doll conventionally, for instance, a front half constituting one half of a doll body, a rear half constituting the other half of a doll body and a set of head, hands and legs connected by a molding gate are molded separately. Thereafter, the head, hands and legs are separated from the gate one by one; the separated parts are independently arranged between the two halves one by one before fixing the two halves with the parts sandwiched therebetween. To improve the productivity, the various parts are molded, in connection with plural molding gates, at such positions that these parts are appropriately supported by and/or engageable with the front and rear halves. Therefore, it is possible to assemble the plastic toy doll immediately without separating various parts one by one from the gate before assembling the toy doll. The molding gates may be broken, after assembling, by twisting the hands or legs.
