Abstract
The utility model discloses a steel-casting die, which comprises two half dies which are divided longitudinally, wherein a plurality of pairs of radial Y-type ear plates are respectively arranged on the two sides of the two half dies at intervals along the longitudinal direction, after the two half dies are closed together, a longitudinal die cavity with an opening end and a plugged end is formed at the inner cavity of a steel die, a layer of demoulding film covers the surface of the longitudinal die cavity, and the thickness of the demoulding film is 0.2mm-0.4mm. A casting port magnesium-based coating with the thickness larger than the demoulding film also covers on the casting port of one half die, wherein the casting port of the half die is contacted with high-temperature molten steel at first. The magnesium-based coating has high temperature resistance and large heat absorption, when the high-temperature molten steel passes by the magnesium-based coating on the casting port, the magnesium-based coating quickly and greatly absorbs heat, the high temperature is instantly reduced, and the problems of the deformed and molten casting port and die adhered with cast steel blanks due to the washing of the high-temperature molten steel to the steel die are effectively solved. The service life of the die is above three times of that of the existing die, and the production cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of steel-casting mould, but the cylindricality steel-casting mould that particularly a kind of two halves separate belongs to the cast steel technical field.
Background technology
The cylindricality steel-casting adopts two-half die matched moulds casting as high-speed steel circular shaft shape cast steel blank, die joint is located on the diametrical position, and two half module both sides longitudinally are interval with several radially fork-shaped otic placodes to the steel mould that is used to lock.Behind two half module matched moulds, form vertical die cavity that an end opens wide, the other end stops up.The cast steel base does not stick together with die cavity in order to prevent to cast afterwards, cover one deck mold release film in cavity surface, but when casting, high-temperature molten steel at first contacts the punching block casting gate, cause the distortion of die casting mouth to melt the cast steel blank and be difficult to the demoulding, the service life of mould is short, has only about 15 times, mould consumption is big, has strengthened production cost.
Summary of the invention
The purpose of this utility model provides a kind of long service life, die casting mouth be difficult for the deforming steel-casting mould of thawing, the easy demoulding of cast steel blank.
The utility model is achieved by the following technical programs:
A kind of steel-casting mould, two half modules that comprise vertical subdivision, described two half module both sides longitudinally are respectively equipped with at interval several to fork-shaped otic placode radially, behind two half module matched moulds, the punching block inner chamber forms vertical die cavity that an end opens wide, the other end stops up, described vertical cavity surface covers one deck mold release film, and the thickness of described mold release film is 0.2mm～0.4mm; At first contact at high-temperature molten steel on the half module of casting gate and also covered the casting gate magnesium base coating of a layer thickness greater than mold release film.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid steel-casting mould, the thickness of wherein said casting gate magnesium base coating is 1.5～2.5mm, the length of described casting gate magnesium base coating is 180～220mm.
The utility model is a support with molten steel fluid contact radiating principle, has also covered the casting gate magnesium base coating of a layer thickness greater than mold release film on the casting gate of the half module that high-temperature molten steel at first contacts.Magnesium base coating is a primary raw material with magnesium and calcium oxide, and is high temperature resistant, heat absorption is fast.When the magnesium base coating on the high-temperature molten steel process casting gate, the quick and a large amount of heat absorptions of magnesium base coating, high temperature moment passage has solved high-temperature molten steel effectively and washing away of punching block has been caused casting gate be out of shape thawing and cast steel blank sticking to mould problem.Bring up to 50 time or more from present about 15 times the service life of mould, for more than three times of existing mold life-span, greatly reduces production cost.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model comprises two half modules 1 of vertical subdivision, described two half module 1 both sides longitudinally are respectively equipped with at interval several to fork-shaped otic placode 2 radially, behind two half module 1 matched moulds, the punching block inner chamber forms vertical die cavity 11 that an end opens wide, an end stops up, described vertical die cavity 11 surface coverage one deck mold release film 3, the thickness of described mold release film 3 is 0.2mm～0.4mm.At first contact at high-temperature molten steel on the casting gate of a half module and also covered the casting gate magnesium base coating 4 of a layer thickness greater than mold release film 3, the thickness B of described casting gate magnesium base coating 4 is 1.5～2.5mm, and the length L of casting gate magnesium base coating 4 is 180～220mm.The thickness B of present embodiment casting gate magnesium base coating 4 is 2.0mm, and the length L of casting gate magnesium base coating 4 is 200mm.When the utility model was used to cast circular shaft form height speed steel casting, two half module 1 locking backs became a head height, a low tilting state, exhaust when being convenient to cast, the quality of raising steel-casting
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
