Abstract
The utility model discloses a gate stick for casting a train friction block. The gate stick comprises a pouring cup (1) and a sprue (2), wherein the sprue (2) is provided with a first internal gate (3), a second internal gate (4) and a third internal gate (5) which are respectively connected with a first gate, a second gate and a third gate on a friction block wax mold; each of the first internal gate (3) and the third internal gate (5) is provided with two symmetrically arranged insulation boards (6), and the free end of each insulation board (6) extends horizontally along the direction that the friction block wax mold is arranged. According to the gate stick for casting the train friction block, the internal shrinkage porosity of the friction block can be eliminated during casting.
Description
Technical field
The utility model relates to model casting technical field, is specifically a kind of for casting the gate stick of train brake pad.
Background technology
Model casting, claim again to lose cured method, it is will cast the mould of implements with cured making, then on cured mould, coats mud, form mud mould, after drying Deng mud mould, then roasting Cheng Taomo, in the process of roasting, cured mould all melts loss, surplus Tao Mo only, then the sprue gate staying during from mud mould processed pours into molten metal, just makes required implements after cooling.In the model casting of prior art, the design of pouring and riser systems directly has influence on the precision of foundry goods, pouring and riser systems generally comprises cup, sprue and ingate, cup is connected to the upper end of sprue, on sprue, be evenly distributed with a plurality of ingates, the corresponding die cavity that is communicated with a foundry goods of each ingate, is called gate stick by cup and sprue merging conventionally.
At present, the brake pad using on train (as shown in Figure 1), its structure comprises brake pad body 101, the two side of this brake pad body 101 is all outwards provided with projection 102.In casting during this brake pad, make the first cast gate 103, the second cast gate 104 and the 3rd cast gate 105 on brake pad wax-pattern body respectively with gate stick (as shown in Figure 2) on the first ingate 203, the second ingate 204 and the 3rd ingate 205 assembly weldings; In when casting because the cross section of the first cast gate 103 on brake pad wax-pattern body and the 3rd cast gate 105 is less, and the thickness of the projection 102 of brake pad wax-pattern body both sides and brake pad wax-pattern body sidewall is thicker, molten steel is when flowing through the first cast gate 103 and the 3rd cast gate 105, cooling very fast, make brake pad body sidewall and projection not have enough molten steel to carry out feeding, thereby make sidewall and projection inner generation shrinkage porosite or the shrinkage cavity of the brake pad after casting, the brake pad casting out can not meet the requirement of the high-compactness of this interiors of products, and defect rate is high.
Utility model content
The technical problems to be solved in the utility model is, overcomes the defect of above prior art, provide a kind of when casting, can eliminate the inner shrinkage porosite of brake pad for casting the gate stick of train brake pad.
Technical solution of the present utility model is, provide a kind of have following structure for casting the gate stick of train brake pad: it comprises cup and sprue, described sprue is provided with respectively the first ingate, the second ingate and the 3rd ingate being connected with the first cast gate, the second cast gate and the 3rd cast gate on brake pad wax-pattern, on described the first ingate and the 3rd ingate, be equipped with two symmetrically arranged warming plates, and the free end of each warming plate extends to the direction of brake pad wax-pattern.
Adopt after above structure, the utility model for the gate stick of casting train brake pad compared with prior art, have the following advantages: this gate stick in use, make the first ingate of gate stick, the second ingate and the 3rd ingate respectively with brake pad wax-pattern on the first cast gate, the second cast gate is connected with the 3rd cast gate, when fusible pattern is cast, after warming plate thawing due to the first ingate and the 3rd ingate place, be filled with the insulation effect of molten steel, make molten steel on flowing through brake pad wax-pattern when the first cast gate and the 3rd cast gate, can be not cooling very soon, so just delayed the cool time of the first cast gate and the 3rd cast gate place molten steel, guarantee that molten steel is fully filled with brake pad wax-pattern, make sidewall and the projection inside of the brake pad after casting can not produce shrinkage porosite or shrinkage cavity, meet the requirement of the high-compactness of this interiors of products, the brake pad percent defective of casting is low.
As preferably, described warming plate is the thick and middle smooth continuous warming plate in thin the inner, outer end.The design of this shape warming plate can realize the consecutive solidification of brake pad when casting, also from brake pad, this brake pad of a side direction away from gate stick solidifies sequentially near a side of gate stick, so just prevents that the sidewall of brake pad and projection inside from can not produce shrinkage porosite or shrinkage cavity well.
As preferably, the width of described warming plate is at least the twice of brake pad wax-pattern wall thickness and bump width sum.Warming plate just can have enough temperature to guarantee to delay the consecutive solidification requirement of the cooling and brake pad of the first cast gate and the 3rd cast gate place molten steel like this.
