Problems solved by technology
[0002] The existing products with threaded structure on the inner wall have only one cavity in a mold, and the threaded insert is placed in the cavity. When the mold needs to be demolded, the guide post drives the threaded insert to rotate. The spiral rotation of the product is separated from the threaded insert. Since there is only one cavity in a mold, when the product needs to be mass-produced, the production efficiency is low, and the labor time of the workers is long, time-consuming and labor-intensive.

The invention provides a lateral one-mold double-cavity threaded demolding structure. According to the invention, two products can be formed in one mold at the same time, the production efficiency is improved, the labor time of workers is saved, and time conservation and labor conservation are realized. The lateral one-mold double-cavity threaded demolding structure comprises a front mold, a rear mold and mold inserts, wherein external threads are arranged on the mold inserts; the lateral one-mold double-cavity threaded demolding structure is characterized in that two cavities are formed between the front mold and the rear mold; the mold inserts are lateral inserts; the external thread parts of the corresponding mold inserts are respectively mounted in the cavities in an inserting way; the outer sides of the mold inserts are respectively in fastening connection with corresponding rotating shafts; the front mold and the rear mold are mounted with a supporting block which is positioned on one side of each of the rotating shafts and is positioned in an outer-side mounting cavity formed between the front mold and the rear mold; the supporting block is fastened with 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 supporting block and are in threaded connection with the supporting block.
Description
technical field [0001] The invention relates to the structural technical field of product molds, in particular to a side threaded demoulding structure with one mold and two cavities. Background technique [0002] The existing products with threaded structure on the inner wall have only one cavity in a mold, and the threaded insert is placed in the cavity. When the mold needs to be demolded, the guide post drives the threaded insert to rotate. The spiral rotation of the product is separated from the threaded insert. Since there is only one cavity in a mold, when the product needs to be produced in large quantities, the production efficiency is low, and the labor time of the workers is long, time-consuming and labor-intensive. Contents of the invention [0003] The invention provides a single-mold double-cavity spiral ejection structure, which enables one mold to form two products at one time, improves production effic...
