Abstract
The invention provides a casting method capable of eliminating air holes in a machine tool casting. The casting method includes the steps of firstly, setting a casting system, wherein the casting system comprises the machine tool casting, a machine tool casting lower portion is connected with an internal runner mounted below a transverse runner, the transverse runner is connected with a straight runner, and an upper-plane inner runner is arranged between each of the three machining faces of the upper plane of the machine tool casting and the transverse runner; secondly, pouring at 1380-1390 DEG C for 53-58 seconds with the pouring weight being 4400kg, and allowing molten iron to sequentially enter the straight runner, the transverse runner and the internal runner through a sprue cup and to be injected into a cavity from the bottom; thirdly, allowing the molten iron to enter the upper plane of the machine tool casting from the straight runner, the transverse runner and the upper-plane inner runners. The casting method has the advantages that the three inner runners are added to the upper plane of the casting to respectively guide in the molten iron from the upper-portion machining faces, up-down temperature difference is small, bubbles in the molten iron can be smoothly discharged out of the cavity, casting time is short, the quality of the casting is increased, and waste products are reduced.
Description
Technical field
The present invention relates to casting technology field, relate in particular to a kind of casting method of eliminating lathe casting inner air vent.
Background technology
43M bed piece overall size is 2700 × 2100 × 900, rail thicknesses is 120, average wall thickness 30,3800 kilograms of weight, material is HT350, on machined surface, do not allow any defect, internal structure more complicated, is convenient to core under moulding for ensuring the quality of products, below guide rail is placed in, foundry goods is mainly at mo(u)ld bottom half, and when cast, iron liquid injects die cavity by cup from bottom. This casting mode is because foundry goods height is higher, iron liquid rises on foundry goods temperature step-down after plane, viscosity is large, owing to being HT350 material, its mobility is poor, and the speed that gas that iron liquid is involved in cavity filling process rises slows down, and is finally trapped in foundry goods inside and causes and on foundry goods, after plane machining, have gas hole defect, casting quality is poor, and percent defective is higher.
Summary of the invention
The present invention provides a kind of casting method of eliminating lathe casting inner air vent in order to address the above problem.
Technical scheme of the present invention is achieved in that a kind of casting method of eliminating lathe casting inner air vent, comprise the following steps: (1), running gate system is set, running gate system comprises lathe casting, lathe casting bottom is connected with ingate, cross gate below is equipped with ingate, cross gate is connected with sprue, on lathe casting, between three of plane machined surfaces and cross gate, plane ingate is set respectively;
(2), 1380～1390 DEG C of pouring temperatures, poured weights 4400kg, 53～58 seconds durations of pouring, iron liquid enters sprue, cross gate and ingate successively by cup, injects die cavity from bottom;
(3) the upper plane that, iron liquid enters lathe casting from sprue, cross gate and plane ingate simultaneously.
The invention has the beneficial effects as follows: the present invention's plane on foundry goods increases by three Inner running channels and introduces respectively iron liquid from machined surface position, top, not only for having increased high temperature iron liquid herein, improve again the die cavity temperature in this region, upper and lower temperature difference diminishes, the resistance force diminishes of gas floating in iron liquid, the bubble being involved in molten iron can successfully be discharged die cavity, and casting time is short, improve casting quality, reduced the generation of waste product.
Brief description of the drawings
Fig. 1 is the structural representation of casting system of the present invention;
Fig. 2 is the side view of casting system of the present invention.
Part explanation: 1, lathe casting, 2, sprue, 3, upper plane ingate, 4, machined surface, 5, cross gate, 6, ingate.
Detailed description of the invention
For Comprehension and Implementation better, below in conjunction with accompanying drawing, the invention will be further described: a kind of casting method of eliminating lathe casting inner air vent, comprises the following steps:
(1), casting system is set, casting system comprises lathe casting 1, and lathe is cast 1 bottom and is connected with ingate 5, and cross gate 5 belows are equipped with ingate 6, cross gate 5 is connected with sprue 2, on lathe casting 1, between three of plane machined surfaces 3 and cross gate 5, plane ingate 3 is set respectively; (2), 1385 DEG C of pouring temperatures, poured weights 4400kg, 54 seconds durations of pouring, iron liquid enters sprue 6, cross gate 5 and ingate 6 successively by cup, injects die cavity from bottom; (3), iron liquid enters in the upper plane of lathe casting 1 from sprue 6, cross gate 5 and plane ingate 3 simultaneously.
The present invention's plane on foundry goods increases by three Inner running channels and introduces respectively iron liquid from machined surface position, top, not only for having increased high temperature iron liquid herein, improve again the die cavity temperature in this region, upper and lower temperature difference diminishes, the resistance force diminishes of gas floating in iron liquid, the bubble being involved in molten iron can successfully be discharged die cavity, and casting time is short, improve casting quality, reduced the generation of waste product.
