Abstract

The utility model provides a connecting piece casting sand mould, comprising a pouring cup and a plurality of casting chambers. The connecting piece casting sand mould is characterized by further comprising a feeding chamber communicated with all casting chambers through a plurality of cross gates, wherein the top end of the feeding chamber is communicated with the first cross gate; the first cross gate is communicated with the pouring cup through a straight gate. An air discharge duct is arranged at one end of the casting chamber in the axial direction; a sand core is arranged in the casting chamber; and core head air discharge ducts are arranged on the core heads at the two ends of the sand core. The casting sand mould provided by the utility model has the advantages that one feeding chamber is communicated with the plurality of casting chambers, only one pouring cup is arranged, the pouring process of each casting is carried out synchronously and the stability of the properties of the casting is improved; the problem of difficult outward discharge of air in the lower end of a cavity is solved by virtue of the air discharge ducts arranged at both ends, and shortcomings of the casting caused by shrinkage holes, air holes and the like are reduced.

Description

Connector casting sand mo(u)ld
Technical field
The utility model relates to a kind of connector casting sand mo(u)ld, specifically is applied to the connector that pipeline connects.
Background technology
The connector of pipeline connection usefulness is strict for sealing, mechanical performance and chemical composition.At present, the casting sand mo(u)ld of connector foundry goods, water a glass upper end that is arranged on casting mold, several foundry goods chambeies can be arranged, generally have two, each foundry goods chamber is provided with dead head, this casting sand mo(u)ld is owing to being provided with separately dead head, the bad control of iron liquid casting time on two foundry goods chambeies, easily cause asynchronously, the cast properties that forms out is variant.Simultaneously, because water the upper end that cup is arranged on casting mold, the molten iron that enters from the upper end ingate flows downward, and stops gas upwards to be discharged, and easily forms the intensive pore in the middle and upper part, and the result causes the connector after the moulding to have the defectives such as shrinkage cavity, pore.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of connector casting sand mo(u)ld, the uniformity of raising foundry goods, the percent defective of reduction foundry goods.
The technical solution of the utility model is:
A kind of connector casting sand mo(u)ld, comprise and water cup and several foundry goods chambeies, it is characterized in that: it also comprises a feeding chamber that is communicated with all foundry goods chambeies by some cross gates, and top, described feeding chamber is communicated with the first cross gate, and described the first cross gate is communicated with the described cup that waters by sprue.
In preferred embodiment of the utility model, comprise that further the axial end in described foundry goods chamber is provided with air discharge duct.
In preferred embodiment of the utility model, further comprise in the described foundry goods chamber being provided with core, the core print at described core two ends is provided with the core print air discharge duct.
In preferred embodiment of the utility model, comprise that further bottom, described feeding chamber is provided with cushion chamber.
The beneficial effects of the utility model are:
1, the utility model adopts a feeding chamber to be communicated with several foundry goods chambeies, and a dead head only is set, and iron liquid enters each foundry goods die cavity through watering cup, sprue, cross gate, feeding chamber, and casting process carries out synchronously, improves the stability of each cast properties.
2, the utility model is equipped with air discharge duct at the axial two ends of core, the gas of upper end is discharged from upper air discharge duct in the die cavity, the gas of lower end is discharged from lower air discharge duct, utilize two ends all to establish the gas that air discharge duct solved the die cavity lower end and upwards discharge hard problem, reduced bad because of shrinkage cavity, pore etc. of foundry goods.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment.
2, water cup, 4, the foundry goods chamber, 6, the feeding chamber, the 8, first cross gate, 10, sprue, 12, air discharge duct, 14, core, 16, the core print air discharge duct, the 18, second cross gate, 22, cushion chamber.
The specific embodiment
In order to make those skilled in the art person understand better the present invention program, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with embodiment and embodiment accompanying drawing.
As shown in Figure 1, a kind of connector casting sand mo(u)ld, comprise and water cup 2 and several foundry goods chambeies 4, select two foundry goods chambeies that the structure of connector casting sand mo(u)ld is described in the present embodiment, certainly, expand based on the utility model structure, the foundry goods chamber can be designed to four, six, eight etc., fully according to need of production.Also comprise feeding chamber 6, sprue 10, cushion chamber 22 and cross gate, cross gate has the first cross gate 8, the second cross gate 18, foundry goods chamber 4 is communicated with feeding chamber 6 by the second cross gate 18,6 bottoms, feeding chamber are communicated with cushion chamber 22,6 tops, feeding chamber are communicated with sprue 10 by the first cross gate 8, sprue 10 with water glasss 2 and be communicated with.Adopt a feeding chamber to be communicated with a plurality of foundry goods chamber, a dead head only is set, iron liquid enters each foundry goods die cavity through watering cup, sprue, cross gate, feeding chamber, and casting process carries out synchronously, improves the stability of each cast properties.
4 axial ends are provided with air discharge duct 12 in the foundry goods chamber, be provided with core 14 in the foundry goods chamber 4, be equipped with core print air discharge duct 16 on the core print at core 14 two ends, be equipped with the core print air discharge duct by the core two ends, the gas of upper end is discharged from upper air discharge duct in the die cavity, the gas of lower end is discharged from lower air discharge duct, utilize two ends all to establish the gas that air discharge duct solved the die cavity lower end and upwards discharge hard problem, has reduced bad because of shrinkage cavity, pore etc. of foundry goods;
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
