Abstract
The utility model discloses a plunger piston head, which comprises a base body and an outer sleeve, wherein the front end of the outer sleeve is inserted into the base body, the center of the outer sleeve and the center of the base body are provided hollow parts, the front end of the base body is the base body end surface, the hollow part of the base body does not penetrate through the base body end surface, the hollow part of the outer sleeve penetrates through the whole outer sleeve, the hollow part of the base body is in butt joint with the hollow part of the outer sleeve, the plunger piston head is also provided with a cooling liquid pipe, the cooling liquid pipe passes through the hollow part of the outer sleeve to be communicated with the hollow part of the base body, the base body end surface is provided with a nanometer coating, and a sealing ring is arranged in a contact position of the front end of the outer sleeve with the base body. The plunger piston head has the advantages that the nanometer coating is arranged at the base body end surface of the plunger piston head, so the whole plunger piston head has higher wear resisting performance, in addition, cooling liquid is filled into the plunger piston head through the cooling liquid pipe, the work temperature of the plunger piston head is reduced, a protection effect is realized on the plunger piston head, and the service life of the plunger piston head can be prolonged. In addition, because the technical scheme is adopted, the production process of the plunger piston head is simpler, and the production cost is lower.
Description
Technical field
The utility model relates to the mechanical industry product technical field, is specifically related to a kind of stopper head that is used for machineries such as die casting machine.
Background technology
The stopper head that uses in the equipment such as present die casting machine adopts the casting of ferrous metal magnesium iron to form usually, and its shortcoming is not wear-resisting, and wearing and tearing are very severe in process of production; Need often to change; Not only cause waste of material, and can delay production, and cause production cost to increase.In order to address this problem; Someone adopts two kinds of different materials to make two independent sectors of stopper head respectively; Usually need wear-resisting part to adopt wear-resisting, high strength tremendous effort non-ferrous metal such as beryllium-bronze to make; Yet this scheme can cause the production technology of stopper head more complicated, and production cost is also higher.In addition, when work, the stopper head temperature inside is very high, generally can reach about 700 degree, and so high temperature also can shorten the service life of stopper head.
The utility model content
The technical problem that the utility model will solve provide a kind of simple in structure, production cost is low, anti-wear performance good, the stopper head of long service life.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of stopper head is characterized in that: comprise matrix and overcoat, the front end of overcoat is inserted among the matrix; Matrix and overcoat center all offer hollow bulb, and the front end of matrix is the matrix end face; The hollow bulb of matrix does not penetrate the matrix end face, and the hollow bulb of overcoat runs through whole overcoat, and the hollow bulb of matrix docks with the hollow bulb of overcoat; This stopper head also is provided with coolant pipe, and coolant pipe passes the hollow bulb of the hollow bulb one of overcoat through to matrix; Cooling fluid flow into the hollow bulb of matrix from coolant pipe, flows out and by special retracting device recycling from the hollow bulb of overcoat then.
Further, the matrix end face of said matrix is provided with nano coating, and this nano coating makes the matrix end face have extraordinary anti-wear performance.
Further, the contacted position of the front end of overcoat and matrix is provided with sealing ring.
Further, said sealing ring is a rubber seal, prevents that cooling fluid from leaking.
Further, overcoat is fixing through being threaded with matrix.
The utility model is provided with nano coating through the end face at the stopper head matrix; Thereby make whole stopper head have higher anti-wear performance; And pass through coolant pipe to the inner cooling fluid of injecting of stopper head; The temperature of reduction stopper head when work shields to stopper head, thereby can prolong the service life of stopper head; Owing to adopt above-mentioned technology, make that the production technology of the utility model is more simple in addition, production cost is lower.
Description of drawings
Fig. 1 is the utility model cross-sectional view.
Among the figure, 1 is matrix, and 2 is overcoat, and 3 is the matrix end face, and 4 is hollow bulb, and 5 is coolant pipe, and 6 is sealing ring.
The specific embodiment
In the present embodiment, with reference to Fig. 1, said stopper head comprises matrix 1 and overcoat 2, and the front end of overcoat 2 is inserted among the matrix 1; Matrix 1 and overcoat 2 centers all offer hollow bulb, and the front end of matrix 1 is a matrix end face 3; The hollow bulb 4 of matrix 1 does not penetrate matrix end face 3, and the hollow bulb of overcoat 2 runs through whole overcoat 2, and the hollow bulb 4 of matrix 1 docks with the hollow bulb of overcoat 2; This stopper head also is provided with coolant pipe 5, and coolant pipe 5 passes the hollow bulb 4 of the hollow bulb one of overcoat 2 through to matrix 1; Cooling fluid flow into the hollow bulb 4 of matrix 1 from coolant pipe 5, flows out and by special retracting device recycling from the hollow bulb of overcoat 2 then.
The matrix end face 3 of matrix 1 is provided with nano coating, and this nano coating makes matrix end face 3 have extraordinary anti-wear performance.
The front end of overcoat 2 and matrix 1 contacted position are provided with sealing ring 6.
Said sealing ring 6 is a rubber seal, prevents that cooling fluid from leaking.
Overcoat 2 is fixing through being threaded with matrix 1.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
