Abstract

The invention relates to a casting technology, in particular to a core embedding casting method for a middle trough casting, and solves the technical problems of low casting quality, low efficiency and the like due to low core setting quality in the conventional casting process. The core embedding casting method for the middle trough casting comprises the following steps of: arranging a core box at a sand core of the casting according to a part drawing of the casting; hammering the sand core according to the core box, and embedding the manufactured sand core into a mold in advance before molding; and starting a sand mixer for molding, directly taking the mold out to ensure that the sand core is directly embedded into a sand mold, and casting. By the casting method, the position of the sand core is very accurate, the sand mold is compact, casting quality is ensured, and production efficiency is improved.

Description

Intermediate channel foundry goods superimposed core casting
 
Technical field
The present invention relates to a kind of foundry engieering, be specially a kind of intermediate channel foundry goods superimposed core casting.
Technical background
The present casting production process of my company is fat hardened sodium silicate sand casting technique, produces main scrapper conveyor ledge, support needling, the belt feeder parts etc. produced.Wherein casting quality directly has influence on quality and the market competitiveness of our mechanized equipment, in order to improve the foundry goods comprehensive quality, satisfies the development that group company's high-end coal machine product forms a complete production network demand and progressively adapts to the market external environment condition.We must improve the quality of foundry goods.Through years of work, we find that according to normal casting technique requirement all foundry goods all are after moulding, carry out lower core according to the various shape needs of part.Play like this core foundry goods out following problem to occur easily: 1, the position of core is offset easily under the foundry goods, causes foundry goods to be scrapped; 2, the slit consolidation is inadequate during lower core, and molten steel is string disorderly, and more skin seam, the bad cleaning of foundry goods appear in cast(ing) surface; 3, core can't be played in the position that has of part foundry goods.The problem that the existence of this problem brings is that casting quality has flaw, percent defective height, operating efficiency reduction.
Summary of the invention
The present invention for the lower core that solves existing casting technique and exist of low quality cause casting quality poor, the technical problem such as efficient is low provides a kind of intermediate channel foundry goods superimposed core casting.
Technical scheme of the present invention is, a kind of intermediate channel foundry goods superimposed core casting at first according to the foundry goods part drawing, designs core box on the position with sand cores of castings, then accomplish fluently core according to core box, before moulding, the core of having made is embedded on the mould in advance, then open puddle mixer and carry out moulding, after having made type, direct delivery, core just directly is embedded in the sand mold like this, casts again.
Compared with prior art, the present invention is embedded in core on the mould first, and then to the die modeling with core, taking-up mould after moulding is finished, core are then stayed in the sand mold, guarantees that so at first the position of core is very accurate, guarantees not occur waste product; Secondly, the sand mold of making is consolidation relatively, the skin seam especially can not occur in the position of core, has guaranteed cast surface quality, has particularly reduced the burr of foundry goods post processing; Again, simple in structure, easy to operate, cost is low; To the part of any shape, can adopt this method of burying in advance core, the part of having avoided some special shape just can't play the situation of core according to existing technique, has improved production efficiency.
The specific embodiment
Embodiment 1,A kind of intermediate channel foundry goods superimposed core casting, at first according to the foundry goods part drawing, design core box on the position with sand cores of castings, then accomplish fluently core according to core box, before moulding, be embedded in advance the core of having made on the mould, then open puddle mixer and carry out moulding, made type after, direct delivery, core just directly is embedded in the sand mold like this, casts again.

Claims (1)

1. intermediate channel foundry goods superimposed core casting, it is characterized in that: at first according to the foundry goods part drawing, design core box on the position with sand cores of castings, then accomplish fluently core according to core box, before moulding, be embedded in advance the core of having made on the mould, then open puddle mixer and carry out moulding, made type after, direct delivery, core just directly is embedded in the sand mold like this, casts again.
