Patent ID: 8038921

Claim:
A process for producing a molded object with an embedded member, comprising a first step of heating to a given temperature, a mold which is formed with a gate capable of packing a thermoplastic resin therethrough, and in which a plurality of pins extending from the outside to the inside of the mold are withdrawable outward; a second step of supporting a member to-be-embedded which is embedded in the thermoplastic resin, including an upper part side thereof, with the pins, so as to hold the member to-be-embedded at a given position within the mold; a third step of packing the thermoplastic resin in a pressurized state from the gate into the mold, wherein initially introduced resin enters the mold in an upward direction against a downwardly facing side of the member to-be-embedded, so that the upwardly flowing resin exerts an upward force on the member to-be-embedded and causes the member to-be-embedded to be pressed upwardly against the pin on an upper part side of the mold; a fourth step of packing the thermoplastic resin into the remaining part within the mold; and a fifth step of withdrawing the pins successively from a lower part side of the mold, before the thermoplastic resin cools down to a temperature at which it solidifies and loses its flowability, said fifth step started during the fourth step, so gravitational movement of the member to-be-embedded is opposed by the upward force of the pressurized thermoplastic resin being packed into the remaining part within the mold.
