An apparatus for producing a soap cake comprising a mold which has a cavity of prescribed shape, a feed passage for feeding molten soap to the cavity, and means for pushing molten soap remaining in the feed passage at the time of feeding molten soap to the cavity to remove molten soap remaining in the feed passage. One end of the feed passage is a gate, in which a gate pin for shutting the connection between a feed port and the cavity is slidably provided. As the gate pin advances, molten soap remaining in the feed passage is removed in the step of feeding molten soap to the cavity.

What is claimed is: 1. A method of producing a soap cake which comprises: moving one of a separate nozzle and a feed port of a mold to insert said nozzle into said feed port of said mold such that the nozzle moves in a first direction relative to the feed port during insertion of the nozzle; feeding molten soap to be metered from a molten soap source to the mold having a cavity of prescribed shape, a gate leading to said cavity, and a gate pin slidably provided in said gate, said feeding being through said nozzle, said feed port, and said gate, and pushing said gate pin through said gate while maintaining the feed of said molten soap into said cavity from the molten soap source to plug said gate thereby to stop said feeding and to press the molten soap remaining in said gate into said cavity, wherein the gate pin moves in a second direction, different from the first direction during said pushing. 2. The method according to claim 1, wherein said gate is located under said cavity, and the molten soap is fed in the upward direction from the lower part of said cavity. 3. A method of producing a soap cake which comprises: feeding molten soap from a molten soap source to a mold having a cavity of prescribed shape, a gate leading to said cavity, a gate pin slidably provided in said gate, said feeding being through said gate, and at a time when the gate is at least partially open with respect to the gate pin, removing the molten soap remaining in said gate out of said mold by suction while pushing said gate pin. 4. A method of producing a soap cake comprising: feeding molten soap to the cavity of prescribed shape of a mold through a feed passage leading to said cavity and solidifying the molten soap, wherein said feed passage is formed of at least a gate which is formed in said mold and leads to said cavity and an injection nozzle directly connected to said gate; plugging said gate with a gate pin to expel any molten soap remaining in said gate; and plugging said injection nozzle with a plug to expel any molten soap remaining in said injection nozzle, wherein the gate pin and the plug are separately moveable. 5. The method according to claim 4, wherein the molten soap is fed at a low rate in the initial stage of feeding such that air bubbles of sizes perceptible to the eye do not generate and remain in the resulting soap cake, at a higher rate in the intermediate stage of feeding than in the initial stage, and at a lower rate in the final stage of feeding than in the intermediate stage of feeding. 6. The method according to claim 5, wherein a feeder for delivering a set-up volume of the molten soap to said cavity is provided in the upstream of said nozzle with respect to the flowing direction of said molten soap, and the feeding rate of said molten soap is controlled by said feeder. 7. The method according to claim 4, wherein the molten soap is fed to the cavity while adjusting the opening of said feed passage and, simultaneously with the feeding, said feed passage is plugged to expel any molten soap remaining in said feed passage. 8. The method according to claim 7, wherein the opening of said feed passage is adjusted so that the molten soap is fed at a low rate in the initial stage of feeding such that air bubbles of sizes perceptible to the eye do not generate and remain in the resulting soap cake, at a higher rate in the intermediate stage of feeding than in the initial stage, and at a lower rate in the final stage of feeding than in the intermediate stage of feeding. 9. The method according to claim 4, wherein the molten soap is fed in the upward direction from the lower part of said cavity. 10. An apparatus for producing a soap cake comprising: a mold for molding molten soap into a prescribed shape; and an injection section for feeding molten soap to said mold, wherein said mold has a molten soap feed port, said injection section has a nozzle which sticks out from part of said injection section with its diameter decreasing toward the tip thereof and a plug which has substantially the same shape as the inner shape of said nozzle and is slidably disposed in said nozzle, said nozzle is capable of being inserted into said feed port of said mold, at least one of said mold and said nozzle is movable to join with each other and separate from each other, said molten soap feed port is configured to be plugged by a pin, and the pin and the plug are separately moveable. 11. The apparatus according to claim 10, wherein a feeder for delivering a set-up volume of the molten soap to said cavity is provided in said feed pipe in the upstream of said nozzle with respect to the flowing direction of said molten soap, said feeder being capable of adjusting the feed rate so that the molten soap is fed at a low rate in the initial stage of feeding such that air bubbles of sizes perceptible to the eye do not generate and remain in the resulting soap cake, at a higher rate in the intermediate stage of feeding than in the initial stage, and at a lower rate in the final stage of feeding than in the intermediate stage of feeding. 12. The apparatus according to claim 10, wherein said feed port is positioned under the cavity of said mold, and the molten soap is fed in the upward direction from the lower part of said cavity. 13. The apparatus according to claim 10, wherein a feeder for delivering a set-up volume of the molten soap is provided in said feed pipe in the upstream of said nozzle with respect to the flowing direction of said molten soap, and said feeder is equipped with a switchover valve for connecting said feeder alternatively to the upstream or the downstream of said feed pipe. 14. The apparatus according to claim 10, wherein said feed pipe is equipped with a pressure pump which is adapted to feed the molten soap to the cavity of said mold under pressure.
