Abstract
The utility model relates to a piston die used for a piston casting process. The utility model is characterized in that the internal wall of a gating chamber is provided with a concave trough; heat preservation material is fixedly packaged in the concave trough by an iron plate. In the casting process, the high-temperature aluminium liquid does not directly wash the heat preservation material, without the problem of falling of the heat preservation material. Therefore, the utility model has the advantages of good heat preservation effect, stable use effect, and long service life.
Description
The utility model relates to a kind of Piston mould that uses in the piston casting process.
In the piston casting process, cool off in proper order at present, often be coated with the last layer insulation material, reach this control effect by dead head inner surface at Piston mould in order to control high temperature aluminum liquid.Its shortcoming is: insulation material directly is subjected to washing away of high temperature aluminum liquid, easily comes off, and the heat insulation effect instability has shortened service life of Piston mould.
The purpose of this utility model provides a kind of high insulating effect, and the life-span is long, the adeciduate Piston mould of insulation material.
The technical solution of the utility model is: a kind of Piston mould, form by die matrix and dead head, and it is characterized in that: on dead head cavity madial wall, be provided with a groove, the insulation material fixed sealing be contained in the groove with iron plate.
Because adopt said structure, in casting process, high temperature aluminum liquid does not directly wash away insulation material, there is not the insulation material problem that comes off, so high insulating effect, result of use is stable, the life-span is long.
Come the technical solution of the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that A-A among Fig. 1 is to profile.
Fig. 3 is that B-B among Fig. 1 is to profile.
With reference to figure 1, Fig. 2, Fig. 3.Piston mould matrix 1 right part is provided with a dead head 2, is milled with groove 3 on the dead head 2 cavity madial walls, with iron plate 5 insulation material 4 fixed sealing is contained in the groove 3; Insulation material is to be made by asbestos, and what it fills and decide according to the heat insulation effect that will reach; Iron plate 5 is to be welded on the groove, and again through polishing, the last very thin coating of last layer that is coated with on the iron plate surface is bonded on the iron plate in casting process to stop high temperature aluminum liquid, and can improve heat insulation effect and get final product.
