Abstract

The utility model relates to a sand mold of a riser for the placement of a horizontal projected shoulder of a casting, which comprises a sand mold, the sand mold is provided with a casting pattern, the riser and a sand mold runner, the casting pattern is provided with two parallel vertical planes, one vertical plane of the casting pattern is provided with the horizontal projected shoulder, the other vertical plane of the casting pattern is provided with a core, and a position on the core, which corresponds to the horizontal projected shoulder, and communicates with the riser is provided with a horizontal riser neck. Compared with the prior art, the sand mold of the riser has the advantages that: the feeding problem of the projected shoulder in the middle of the casting is solved, the structure is simple, and the effect is good.

Description

A kind of foundry goods level is protruded the sand mold mould that shoulder block is laid rising head

Technical field

The utility model relates to a kind of continuous casting sand mold, relates in particular to a kind of foundry goods level and protrudes the sand mold mould that shoulder block is laid rising head.

Background technology

Usually the structure of foundry goods is a thick middle, and is thinner on every side, as vertical casting technology, protrudes shoulder block for the level of plate casting, because the restriction of die joint has determined the middle thermal center of protrusion shoulder block can not obtain feeding and form shrinkage porosite and shrinkage cavity, causes foundry goods to be scrapped.At this kind situation, common way is to lay chill in the centre, but this kind method easily increases the probability of pore, the change of metallographic and poor processability, and the use of chill shifted the position of thermal center, makes feeding a casting more difficult.

Summary of the invention

The purpose of this utility model is to have proposed the sand mold mould that a kind of foundry goods level protrusion shoulder block is laid rising head for addressing the above problem, in sand mold, lay core, core protrudes shoulder block in foundry goods mould level and is shaped as tapered hole as riser neck, riser neck is communicated with rising head, has solved foundry goods and has protruded the difficult problem of shoulder block feeding.

To achieve these goals, the technical solution of the utility model is: a kind of foundry goods level is protruded the sand mold mould that shoulder block is laid rising head, include a sand mold, cast model, rising head and sand mold cast passage are arranged in the sand mold, described cast model has two vertical planes that are parallel to each other, there is level to protrude shoulder block on one of them vertical plane, another vertical plane of cast model is provided with core, described core is protruding the riser neck that the corresponding position of shoulder block is provided with a level with level, and riser neck is communicated with rising head.

The outlet of described rising head and sand mold cast channel connection.

Described riser neck is a tapered hole riser neck.

The beneficial effect that the utility model is compared the prior art generation is: have the feeding problem of protruding shoulder block in the middle of having solved foundry goods, and simple in structure effective.

Below in conjunction with drawings and Examples the utility model being done one describes in detail.

Description of drawings

Fig. 2 is foundry goods, core and the rising head graph of a relation of the utility model sand mold mould, and the B-B of Fig. 1 is to cross-sectional schematic;

Fig. 3 is foundry goods, core and rising head, the cast passage graph of a relation of the utility model sand mold mould, and the A-A of Fig. 1 is to cross-sectional schematic.

The specific embodiment

A kind of foundry goods level is protruded the sand mold mould embodiment that shoulder block is laid rising head, referring to Fig. 1, Fig. 2 and Fig. 3, described sand mold mould includes a sand mold 1, cast model 2 is arranged in the sand mold, rising head 3 and sand mold cast passage 4, described cast model has two vertical planes that are parallel to each other, there is level to protrude shoulder block 2-2 on one of them vertical plane 2-1, another vertical plane of cast model 2-3 is provided with core 5, described core is protruding the riser neck 5-1 that the corresponding position of shoulder block is provided with a level with level, riser neck is communicated with rising head, the outlet of rising head is normally at the upper surface of sand mold, outlet of the described rising head of present embodiment and sand mold cast channel connection, this kind structure can prevent that foreign material from calling in model from rising head.

Described riser neck is a tapered hole riser neck.Tapered hole can improve the pressure of riser neck port, quickens to reduce the formation of shrinkage cavity to protruding additional that shoulder block shrinks.

Usually the structure of foundry goods is a thick middle, and is thinner on every side, because the restriction of die joint 1-1, what determined middle thermal center can not obtain feeding, and forms shrinkage porosite and shrinkage cavity.

Present embodiment has two protrusion shoulder blocks up and down in conjunction with a kind of example of the iron chair foundry goods on a kind of vertical line making high-speed railway in the middle of the iron chair 2, the shoulder block place forms circles mark place among the thermal center 2-4(figure on foundry goods).The taper hole of square (also can be circle) made in the middle of the core 1 is as riser neck, and rising head is accepted the molten iron of cast passage to the direct feeding of foundry goods thermal center.

Claims

1. a foundry goods level is protruded the sand mold mould that shoulder block is laid rising head, include a sand mold, cast model, rising head and sand mold cast passage are arranged in the sand mold, described cast model has two vertical planes that are parallel to each other, there is level to protrude shoulder block on one of them vertical plane, it is characterized in that another vertical plane of cast model is provided with core, described core is protruding the riser neck that the corresponding position of shoulder block is provided with a level with level, and riser neck is communicated with rising head.

2. a kind of foundry goods level according to claim 1 is protruded the sand mold mould that shoulder block is laid rising head, it is characterized in that the outlet of described rising head and sand mold cast channel connection.
