Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, the drilling mold provided by the present invention includes a mold main body 1 and screws 2 matched with the mold main body, wherein the mold main body 1 is a cylindrical structure, and first drill holes 3 are formed on a front end surface thereof, for example, three first drill holes 3 are provided, and the three first drill holes are uniformly distributed on the front end surface of the mold main body 1; the rear end face of the clamping fixture is provided with a limiting baffle 4, the limiting baffle 4 is used for limiting and connecting screws of a workpiece 5, the limiting baffle 4 and the clamping fixture main body 1 are of an integrated structure, are formed by one-time processing, reduce the processing cost, can be used for multiple times, and have the advantages of simple structure and easiness in manufacturing. Specifically, the center of the limit baffle 4 is provided with a through hole 6, the inner wall of the through hole 6 is provided with internal threads, and the outer wall of the screw 2 is provided with external threads matched with the internal threads of the through hole 6. The side wall of the mould body 1 is provided with a second drilling hole 7, for example, the second drilling hole 7 is one, and is used for positioning the mould, so that the numerical control four-axis positioning is omitted, the operation is simple, a bench worker can conveniently drill holes according to the positioning, and the second drilling hole 7 is communicated with the inner cavity of the mould body 1. The mould main body 1 is internally provided with a cavity for accommodating the workpiece 5 and the screw 2, and the workpiece 5 and the screw 2 are sequentially placed into the cavity and the screw 2 is connected with the mould main body 1 so as to compress the workpiece 5 between the screw 2 and the mould main body 1.
