A titanium plate die body consists of a plurality of titanium plates; a model consisting of two halves is arranged among the titanium plates as required by the rear earth irregular section bar; the titanium plate die body is externally provided with a die body upper shrink-ring and a die body lower shrink-ring; the die body upper shrink-ring and the die body lower shrink-ring are symmetrical shrink-rings; the shrink-rings are connected by metal connection parts; a graphite plate is arranged under the titanium plate die body; a casting hopper is arranged on the titanium plate die body; the periphery of the casting hopper is provided with a hopper shrink-ring; and the hopper shrink-ring is fixedly connected with the casting hopper by the metal connection parts.

Description

The special-shaped section bar casting die of rare earth

Technical field

The utility model relates to the mold and pattern for casting tool, is used for the high pure rare earth metals metallurgy and foundry, particularly relates to a kind of casting die of special-shaped section bar.

Background technology

In high pure rare earth metals is smelted, because rare earth metal fusing point height, chemism are strong.At high temperature very easily have an effect with other media.When producing the rare earth section bar, adopted common steel metal die in the past, and mold materials and rare earth often occurred and produce reaction, in case reagentia has taken place in rare earth metal and mold materials under the high temperature, will in the casting finished product, bring impurity into, influence product purity, finally also can't the demoulding.

The utility model content

The purpose of this utility model provides a kind of mould that at high temperature can not meet extraordinary demand with rare earth metal reaction, the easily demoulding, casting type shape

For achieving the above object, the utility model is taked following technical scheme: the special-shaped section bar casting die of rare earth, comprise: sprue cup, the funnel collar, titanium template die body, the collar on the die body, metal connecting piece, the die body lower collar, graphite cake, titanium template die body is made up of some blocks of titanium plates, be provided with the mould shapes of double combination between the titanium plate by the special-shaped section bar requirement of rare earth, the titanium template die is external to be equipped with the collar and die body lower collar on the die body, the collar and die body lower collar are the collar of symmetry on the die body, the collar connects by metal connecting piece, be placed with graphite cake under the titanium template die body, on the titanium template die body sprue cup is installed, sprue cup is peripherally equipped with the funnel collar, and the funnel collar is fixedlyed connected with sprue cup by metal connecting piece.

The utility model has the advantages that, adopt detachable titanium template die body, make under the hot conditions and can reaction occur, guaranteed the purity of rare-earth products, adopt demountable structure simultaneously, be convenient to the demoulding, the shape of product after the casting is met the requirements with rare earth.

Description of drawings

Fig. 1 is the structure cutaway view that the special-shaped section bar of the utility model waters mold.

Fig. 2 is a K-K cutaway view among Fig. 1.

Among the figure: 1-sprue cup, the 2-funnel collar, 3-titanium template die body, the collar on the 4-die body, 5-screw, 6-die body lower collar, 7-graphite cake.

The specific embodiment

Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments, referring to Fig. 1 and Fig. 2, the special-shaped section bar casting die of rare earth, comprise: sprue cup [1], the funnel collar [2], titanium template die body [3], the collar on the die body [4], metal connecting piece [5], die body lower collar [6], graphite cake [7], it is characterized in that, titanium template die body [3] is made up of some blocks of titanium plates, be provided with the mould shapes of double combination between the titanium plate by the special-shaped section bar requirement of rare earth, the outer collar on the die body [4] and the die body lower collar [6] of being equipped with of titanium template die body [3], the collar on the die body [4] and die body lower collar [6] are the collar of symmetry, the collar connects by metal connecting piece [5], be placed with graphite cake [7] under the titanium template die body [3], sprue cup [1] is installed on the titanium template die body [3], sprue cup [1] is peripherally equipped with the funnel collar [2], and the funnel collar [2] is fixedlyed connected with sprue cup [1] by metal connecting piece [5].

Embodiment:

The titanium template die body [3] that three is had the semicircle type grooving in detachable, be placed on the graphite cake [7], make the collar [4] and die body lower collar [6] on the symmetrical die body with the 45# steel, clamp at two ends up and down at titanium template die body [3] respectively, fix with screw again, a garden bench-type sprue cup [1] is formed with two titanium rings that have been processed into semicircle type in top, the outer ring clamps by bolt with the 45# steel funnel collar [2], titanium sprue cup [1] is placed directly on the titanium template die body [3] of casting, the product of guaranteeing to cast directly advances titanium template die body [3] by sprue cup [1], and the casting product is not outer to be spattered and make.

Claims

1. the special-shaped section bar casting die of rare earth, comprise: sprue cup [1], the funnel collar [2], titanium template die body [3], the collar on the die body [4], metal connecting piece [5], die body lower collar [6], graphite cake [7], it is characterized in that, titanium template die body [3] is made up of some blocks of titanium plates, be provided with the mould shapes of double combination between the titanium plate by the special-shaped section bar requirement of rare earth, the outer collar on the die body [4] and the die body lower collar [6] of being equipped with of titanium template die body [3], the collar on the die body [4] and die body lower collar [6] are the collar of symmetry, the collar connects by metal connecting piece [5], be placed with graphite cake [7] under the titanium template die body [3], sprue cup [1] is installed on the titanium template die body [3], sprue cup [1] is peripherally equipped with the funnel collar [2], and the funnel collar [2] is fixedlyed connected with sprue cup [1] by metal connecting piece [5].
