Abstract

The invention relates to an insulator casting die, an outer die thereof, and an outside square shaping part. The insulator casting die comprises an inner die and the outer die which cooperate with each other in a sleeving manner, a casting cavity for cast molding of an insulator is arranged between the outer die and the inner die, the outer die comprises the outside square shaping part and a coneshaping part which are arranged in a split manner, the axis of the cone shaping part extends along the left and right direction, the outside square molding part is inserted to the cone shaping part, the cone shaping part comprises a cone shaping part inner bore with the axis extending along the left and right direction, the cone shaping part inner bore comprises a conical hole segment having an internal diameter gradually increasing from the left to the right and used for forming the conical surface segment of the insulator, the outside square molding part comprises at least one molding sheet,and the molding sheet has a molding sheet external surface used for being laminated to the hole wall of the tapered hole segment and a molding sheet internal surface used for forming the plane of theinsulator during casting. The cone shaping part and the outside square shaping part are respectively processed, so the processing difficulty is reduced, and the precision is easily guaranteed.

Description

technical field [0001] The invention belongs to the technical field of insulator casting, and in particular relates to an insulator casting mold, an outer mold and an outer molded part thereof. Background technique [0002] When the insulator is cast, the insulator casting mold is used to ensure the shape and size of the insulator. Usually, the insulator casting mold includes an inner mold and an outer mold that are fitted with a sleeve. There is a pouring cavity between the inner mold and the outer mold. Cavity, the shape and size of the inner cavity of the insulator are guaranteed by the inner mold, and the shape and size of the outer shape of the insulator are guaranteed by the outer mold. For such as figure 1 and 2 In the shown insulator, the insulator includes a conical segment 12 with a conical surface and an outer hexagonal segment with an insulator plane 13 on the outer peripheral surface. To ensure the shape of the insulator with this structure, the cavity of the ...
