Embodiment Construction

[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] In the embodiment of the processing method of the outer molding of the insulator casting mold in the present invention, the processing method of the outer molding includes the following steps: the first step is to turn the blank, and process the axis extending along the left and right directions and the outer diameter The conical section that gradually becomes larger from left to right, when turning the conical section, also turns the cylindrical section that is connected to the right end of the conical section and is coaxially arranged with the conical section. The outer diameter of the cylindrical section is larger than that of the conical section. The taper of the conical section matches the taper of the inner hole of the tapered hole section 211 of the corresponding cone forming part 21, and the outer peripheral surface of the cylindrical secti...

Abstract

The invention relates to a machining method for an external molded part of an outer mold of an insulator pouring mold. The machining method for the external molded part comprises the following steps that step1, the lathe machining is performed on blank, a circular cone segment with the axis extending in the left and right direction and the external diameter gradually largening from left to right is machined, and the taper of the circular cone segment is matched with that of an inner hole of a cone-shaped hole segment of a corresponding cone molded part; step2, a circular cone segment center hole which runs through in the axial direction of the circular cone segment is cut out in the middle of the circular cone segment through wire-electrode cutting to make the circular cone segment form one or at least two molded pieces with the thickness gradually thickening from left to right, wherein the one or at least two molded pieces are distributed in the periphery direction, the inner surfaceof each molded piece is of a plane structure which is used for forming an insulator plane in pouring, the machining of the external molded part is simple, and the machining efficiency is high. According to the machining method for the external molded part of the outer mold of the insulator pouring mold, the external molded part is machine by means of the above steps, the realization of separated machining of the external molded part and the cone molded part is facilitated, the machining difficulty of the outer mold is lowered, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of insulator casting, and in particular relates to a processing method for an outer molded part of an outer mold of an insulator casting mold. 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 11 includes a conical segment 12 with a conical surface on the outer peripheral surface and an outer hexagonal segment with an insulator plane 13 on the outer peripheral surface. To ensure the shape of t...
