Description
Technical field
The utility model relates to technical field of mold, is specifically related to a kind of closing-in mould for plunger.
Background technology
Plunger (Fig. 1) is the core component in plunger displacement pump, and itself and piston shoes parts are used in conjunction with.Piston shoes (Fig. 2) have one to accommodate oral pillar plug round end and be placed in this and accommodate mouth, realize plunger round end and in mouth, carry out rotational motion accommodating.And piston shoes mouth is open, therefore piston shoes and plunger round end between to coordinate closing in, plunger round end is shunk and in piston shoes, realizes gap rotating function (Fig. 3).Therefore to invent a kind of mould and realize above-mentioned operation.
Utility model content
For solving the problems of the technologies described above, the utility model provides plunger closing-in mould, provides a kind of piston shoes and plunger realized to realize closing in operation.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of plunger closing-in mould, it comprises mold base, two half modules on described mold base, are arranged symmetrically with, two described half modules be docking together form coupled columns fill in row close up mould, in described half module, comprise the die cavity mouth of circular arc, described die cavity mouth bottom is provided with the lead-in groove tilting to mould inside direction, the bottom of described lead-in groove is provided with guiding gutter and drainage trough, described drainage trough bottom is provided with necking down mouth, and the radius ratio range of the radius of this necking down mouth and die cavity mouth is between 0.6 to 0.8.
Preferably, described half module is that wolfram steel material is made.
Preferably, described mold base is that wolfram steel material is made.
By technique scheme, the plunger closing-in mould that the utility model provides, its beneficial effect is: design a kind of closing-in mould that is specifically designed to plunger, for the closing in of plunger.Guiding gutter is set in mould, and drainage trough carries out water conservancy diversion to metal, prevents the destruction to mould.And compact conformation, effective.
