Abstract
The utility model provides a one-mold two-cavity lateral threaded de-molding structure. Two products can be molded in one mold at one time, so that the production efficiency is improved, the labor time of a worker is saved, and time and labor are saved. The lateral threaded de-molding structure comprises a front mold, a rear mold and mold inserts, wherein the mold inserts are inserts with external threads. The lateral threaded de-molding structure is characterized in that two mold cavities are formed between the front and rear molds, wherein the mold inserts are lateral inserts; the external threads of the mold inserts are correspondingly inserted into the two mold cavities respectively; corresponding rotating shafts are fixedly connected to the outer sides of the mold inserts respectively; a support block is arranged on the sides, with the rotating shafts, of the front and rear molds, is positioned in an outer mounting cavity formed between the front and rear molds, and is fastened on the rear mold; external threads are arranged at the middle parts of the rotating shafts; the middle parts of the rotating shafts penetrate through the support block, and are in threaded connection.
