Abstract
The utility model discloses a piston die of a railway vehicle braking system. The piston die comprises a die main body, a flow gate and a tie bar, wherein the flow gate with large size is arranged on the top of the die main body; and the tie bar is fixed between the upper inner walls of the die main body. The piston die has the advantages that by additionally mounting the tie bar on the die and enlarging the size of the flow gate, the defects that the die has large internal stress, and is easy to rebound and deform are solved; meanwhile, the problems such as shrinkage porosity, pore and shrinkage cavity when the product is produced can be effectively prevented; the product quality is greatly improved; and the enterprise competitiveness is improved too.
Description
Technical field
The utility model relates to a kind of brake system of rail vehicle part mfg. moulding die, specifically a kind of brake system of rail vehicle piston mould.
Background technology
Piston, i.e. the present said piston of people, reciprocating parts in the pump or in the cylinder of steam engine, internal combustion engine.Effect is that the pressure of steam or fuel outburst is become mechanical energy.
In the present locomotive brakes, include the parts such as piston, voussoir, the material of these products uses of the manufacturer production of general these parts of production all is No. 30 steel now, and the tensile strength of this material does not reach requirement.And there is defective in the employed mould structure of manufacturer, so that the deformation of products degree of producing is large.Because the mould internal stress is large, easily bounce-back, therefore easily distortion.And also the problems such as shrinkage porosite, pore, shrinkage cavity can appear when producing product, the quality of product does not reach instructions for use.
The utility model content
For the deficiency that above-mentioned technical problem exists, the purpose of this utility model provides a kind of brake system of rail vehicle piston mould.
The technical solution of the utility model is: brake system of rail vehicle piston mould, comprise die main body, ingate, lacing wire, and it is characterized in that: the top of die main body is provided with large-sized ingate, is fixed with lacing wire between the upper inside wall of die main body.
The utility model has the advantages that: by mould is increased lacing wire is installed, and the size that strengthens ingate, it is large to have solved the mould internal stress, and the problems such as shrinkage porosite, pore, shrinkage cavity appear simultaneously in the shortcoming that rebounds easily and be out of shape in the time of can effectively preventing from producing product.Improve greatly the quality of product, improved the competitiveness of enterprise.
Description of drawings
Fig. 1 is structure cutaway view of the present utility model.
Fig. 2 is top view of the present utility model.
The specific embodiment
Now by reference to the accompanying drawings, technology contents of the present utility model is described further.
As shown in Figure 1, 2, the top of die main body 1 is provided with large-sized ingate 2, is fixed with lacing wire 3 between the upper inside wall of die main body 1.
Claims (1)
1. brake system of rail vehicle piston mould, comprise die main body (1), ingate (2), lacing wire (3), it is characterized in that: the top of die main body (1) is provided with ingate (2), is fixed with lacing wire (3) between the upper inside wall of die main body (1).
