[0002] There is a kind of gasket for mining machinery, which has a special shape. On the outer wall of the barrel-shaped main body of the gasket, there is an annular platform designed as one. Six uniformly distributed holes need to be drilled on the annular platform, and continuous conversion is required. When drilling at an angle, the gasket cannot be directly placed on the bench drill table, and the temperature of the gasket rises during the drilling process, making it inconvenient to touch directly with hands. It is necessary to design a positioning mold to Adapt to drilling needs

Embodiment Construction
[0009] The present invention will be further described below in conjunction with accompanying drawing:
[0010] like figure 1 and figure 2 A positioning mold for gasket drilling is shown, which is composed of an upper mold 1 and a lower mold 2 through a screw 3 and a hexagonal nut 4 matched with the screw 3. The upper mold 1 and the lower mold 2 correspond to The side walls are respectively fixed with long handles 7, 7', the upper mold 1 and the lower mold 2 are both short cylindrical, and the lower end surface of the upper mold 1 and the middle part of the upper end surface of the lower mold 2 are respectively provided with limiting grooves 6 , 6', the diameter and depth of the limit groove 6 of the upper mold 1 are consistent with the shape of the upper half of the barrel-shaped main body of the gasket, and 6 vertically downward positioning through holes are evenly distributed on the upper end surface of the upper mold 1 5. It is consistent with the position on the annula...

The invention relates to a positioning die for gasket drill holes, which is formed by hinging an upper die and a lower die movably by a screw rod and a hexagon nut matched with the screw rod. Long handles are respectively fixed to corresponding side walls of the upper die and the lower die; limit grooves are respectively formed on the middle part of the lower end face of the upper die and the middle part of the upper end face of the lower die; six positioning through holes which are vertical downwards are formed on the upper end face of the upper die uniformly; and corresponding powder leakage holes are formed on the lower die under the positioning through holes. The positioning die has the advantages that: gaskets can be clamped and fixed between the upper die and the lower die to be positioned, the gaskets to be machined are convenient to clamp and move, and the positional deviation of the drill holes can be prevented.
Description
Technical field [0001] The invention relates to a mold for processing mining machinery parts, in particular to a positioning mold for gasket drilling. Background technique [0002] There is a kind of gasket for mining machinery, which has a special shape. On the outer wall of the barrel-shaped main body of the gasket, there is an annular platform designed as one. Six uniformly distributed holes need to be drilled on the annular platform, and continuous conversion is required. When drilling at an angle, the gasket cannot be directly placed on the bench drill table, and the temperature of the gasket rises during the drilling process, making it inconvenient to touch directly with hands. It is necessary to design a positioning mold to Adapt to drilling needs. Contents of the invention [0003] The purpose of the present invention is to provide a positioning mold for gasket drilling, the lower end surface of the upper mold and the middle part of the upper end surface of the lo...
