Problems solved by technology

The casting is a blank, and the surface of the blank is used as the processing reference surface, and its surface finish and dimensional accuracy cannot meet the positioning requirements. Therefore, the current machining process must select one of the six faces of the casting as the processing reference surface, and machine the surface Processing, and then according to this, the remaining five surfaces are processed on the five-sided machining center

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the drawings.

[0021] See figure 1 , First determine the positions of the eight embedded special-shaped nuts 3 on the template 9.

[0022] See figure 2 with image 3 , Set the Hafur movable block 5 at the position where the special nut 3 is to be buried and bury it in the pattern, then put the special nut 3 with bolt 2 into the Hafur movable block 5 and the bolt 2 shall not be completely screwed into the special shape At the bottom of the nut 3, the gap between the bottom of the bolt 2 and the bottom plane of the special nut 3 is filled with refractory nip 7, and then the special nut 3 with the bolt 2 and the Hafur movable block 5 are placed in the recess of the template 9 In the pit; after covering the upper box 1, fill in the molding sand from the upper box 1. After the molding sand is hardened into a sand mold, lift the upper box 1, and the sand mold together with the Hafur movable block 5 and the...

Abstract

The invention relates to the field of casting, in particular to a casting method of a casting with a machining reference. The casting method is characterized in that when a mould is manufactured, the position of a pre-embedded special-shape nut is confirmed on a template and surrounded by a half movable block; a special-shape nut with a bolt is embedded into the half movable block during moulding; when a box is covered, the screwing depth of the bolt is slightly lower than the nut plane, the bolt is filled by refractory mortar, and the periphery of the nut is sealed by a box sealing strip so as to prevent molten iron from entering screw threads during pouring; the bolt is screwed out and the internal screw thread of the nut is tapped by a screw tap during finishing. Compared with the prior art, the invention not only can pre-embed the special-shape nut on the machining reference surface, but also can perform machining positioning by the nut, prevent the machining working procedure of machining the reference surface and save the machining time and cost.

Description

[Technical Field] [0001] The present invention relates to the field of casting, in particular to a casting method with built-in reference castings. [Background technique] [0002] At present, for the mechanical parts processed in general machining centers, one of the sides must be selected as the machining datum surface. In order to make the machining datum plane position accurate, this surface must be machined. Not only is the process cumbersome, but also easy to cause inaccurate machining and time-consuming Laborious. [0003] In order to achieve high precision and high efficiency, the machine tool castings are all processed by a pentahedral machining center, with one clamping and five face machining completed at one time. The premise of this processing method is that the processing datum plane must be determined in order to accurately locate. The casting is a blank, and the rough surface is used as the machining datum surface, and its surface finish and dimensional accuracy ca...
