Technical field:
The utility model relates to mould applications, specifically is a kind of rolling stock bolster integral shooting core box mould.
Background technology:
Railway car partly is made up of car body, bogie, brake apparatus etc., and wherein the effect of bogie is a supporting body, and guided vehicle is exercised along track, and bears the various load from car body and circuit.Bolster is the main support part in the bogie system, and it can make car body change traffic direction, the weight of bearing body on the other hand on the one hand.The rolling stock bolster shooting core box mould of prior art generally combines by six, needs six cover core boxes, and soon six cover core boxes are pieced together and are combined into one; Production efficiency is low; Be easy to generate defective at six cover core box combination joints, reduce the service life (prior art is generally about 15,000 times) of mould, and whole core be formed by connecting several cores also; Reduce the casting accuracy of product, also influenced the intensity of core simultaneously.
The utility model content:
The technical problem that the utility model will solve is, a kind of rolling stock bolster integral shooting core box mould of integral type is provided, and improved the service life of mould and the casting accuracy of product.
The technical solution of the utility model is, a kind of rolling stock bolster integral shooting core box mould of following structure is provided, comprise core box and following core box formation the core box body, penetrate sand plate and plunger tip structure; The die cavity that described core box is up and down formed is rolling stock bolster integral core shooting chamber; Side, described core shooting chamber is provided with tie rod hole and looses core, and describedly penetrates the top that the sand plate is positioned at core box, penetrates the sand plate and is provided with nozzle; Described nozzle is communicated with the die cavity that core box is up and down formed; Described plunger tip structure comprises plunger tip plate and following plunger tip plate, and described plunger tip plate down is arranged on down the below of core box, is equipped with a plurality of push rods on the plunger tip plate about described.
Adopt after the above structure compared with prior art, the utlity model has following advantage: adopt the utility model structure, earlier up and down core box and tie rod hole loose core be connected with equipment respectively after matched moulds, be in locking state; Penetrate the sand plate and pass through nozzle, remove and penetrate the sand plate, by the blowning installation on the equipment core in the die cavity is blown and harden die cavity injection sand; Tie rod hole loosed core open, then upper plate is moved to the core box top, the push rod work on the upper plate also will descend core box and core to eject; Adopt lower roof plate that integral sand core is ejected at last, accomplish a production cycle, next descend core box to be advanced to and penetrate the sand station; The clamping that resets of loosing core moves on the following core box and penetrates the sand position, penetrates sheet reset; Matched moulds clamps up and down, returns to and penetrates the sand state, goes round and begins again; The utility model is an integral type shooting core box mould, need not the combination of many molds, and production efficiency is high, the good and zero defect of type quality, and internal intensity is high, has improved the intensity of core and the service life of mould simultaneously, reaches service life about 60,000 times.
As improvement, described tie rod hole is connected with hydraulic cylinder on loosing core, and like this, tie rod hole is loosed core by hydraulic cylinder control, and making looses core cooperates closely with the hole, and turnover is convenient.
As improvement, the described bottom of core box down is connected with down the plunger tip rebound, and described plunger tip rebound down is connected with following plunger tip plate through connecting rod, and following plunger tip rebound is positioned at the below of plunger tip plate down.In order to satisfy the different needs of core box height down, must not so increase rebound, guarantee the stability of time plunger tip bar simultaneously with descending the plunger tip bar to design longly again simultaneously to prolong the control length of plunger tip plate down.
