Molds, inserts, and fixtures for inserts
The technical solution of this application provides a mold, an insert, and a fixture for the insert. The mold and the insert have mating tenons and mortises. The mortise is open at at least one extended end and forms a draft angle along the extension direction, resulting in a larger space at the opening. The tenon mates with the mortise on the mold and forms a draft angle along the extension direction, resulting in a smaller initial entry end of the tenon into the mortise. The mold and insert of this application achieve precise positioning of the mold and insert through the mating of the tenon and mortise with the draft angle, reducing the positioning accuracy requirements of the fixture and thus improving overall operational efficiency.
