Description

A kind of gate stick coordinated with sand ejection board

Technical field

It the utility model is related to Casting Equipment field, more particularly to a kind of gate stick coordinated with sand ejection board.

Background technology

Running gate system is the passage that liquid metal flows into cavity in casting mold, and the quality of running gate system and casting has close pass System.Sprue cup is a very important component in running gate system, it bears the metal liquid stream from casting ladle and introduces sprue, Prevented from pouring and overflowing；Avoid stream stock from flinging sprue, reduce impact of the liquid stream to casting mold, in addition, sprue cup also have it is certain Pushing off the slag acts on.When being poured into a mould using casting ladle, metal hydraulic head height, impact force is big, and flow is difficult to control, and ladle spout is not easy pair Running channel is collimated, is more needed using sprue cup.

The large enterprise that contemporary foundry industry is especially produced in enormous quantities largely carries out production operation using automatic equipment, After automatic current-following inoculation adder is installed on DISA vertical modeling lines, often generation random inoculant, which is ejected on sand mo(u)ld, makes It is lower than setting value into actual current-following inoculation amount, cause product to occur breeding bad and spoken parts in traditional operas phenomenon；And DISA is vertical at present The pouring cup of mo(u)lding line only tends not to meet production without the effect purified molten metal, rectification is handled by Design of Runner System Quality requires, and the impurity in molten metal can not be handled effectively completely and molten metal turbulent flow causes product to occur largely Sand slag blister and gas hole defect.

Utility model content

In view of the above-mentioned problems, the utility model provides a kind of gate stick coordinated with sand ejection board.

In order to solve the above technical problems, technical solution is used by the utility model：It is a kind of to be poured with what sand ejection board coordinated Mouth rod, it is characterised in that：The gate stick is fixed on sand ejection board by fixed plate, the gate stick include the first gate stick, Second gate stick, cast gate cup body, lead and sprue bush, first gate stick is socketed in sprue cup body, described Second gate stick is socketed in the first gate stick, and the lead is arranged on sprue bush center, second gate stick Equipped with the hollow channel for accommodating lead reciprocating action.

Further, the first gate stick and the second gate stick interference fit.

Further, the socket passage for accommodating the second gate stick reciprocating action is equipped with first gate stick.

Further, first gate stick is interference fitted with cast gate cup body.

Further, the fixed plate is bolted on sand ejection board.

From the above-mentioned description to the utility model structure, compared to the prior art, the utility model has following excellent Point：

1st, the utility model uses split structure, simplifies the structure and processing, manufacturing process of cast gate cup body, and drop Maintenance cost during low renewal part.

2nd, the cooperation of the first gate stick and the second gate stick and lead that the utility model uses, reduces cast gate Rod run-off the straight and stuck possibility, in addition, reducing the abrasion to cast gate cup body, protect gate stick and cast gate cup body etc. Part.
