Abstract
The invention relates to a turnout mould capable of being preheated and cooled and replacing a mould core. The turnout mould is characterized by comprising an upper mould seat, a lower mould seat and removable mould core pieces, wherein the mould core pieces are embedded in the upper mould seat and the lower mould seat and fastened with the upper mould seat and the lower mould seat through fastening bolts; guide sleeves are arranged on the two sides of the upper mould seat; a guide pillar is arranged on the lower mould seat at the position corresponding to the guide sleeve of the upper mould seat; the upper mould seat and the lower mould seat are also provided with cooling holes; and the mould core pieces are provided with heating holes. The turnout mould has the advantages that: when the turnouts with different sizes or shapes are processed, the mould core can be replaced conveniently and quickly; when the mould is used for the first time, the mould is preheated to 200-300 DEG C so as to avoid mould deformation and effectively protect the mould functions; and when the mould is frequently used and the temperature is overhigh, cooling water is fed to cool the mould so as to prevent tensile stress action and cracking phenomenon on the surface of the mould cavity, thereby prolonging the service life of the turnout mould.
Description
Technical field
The invention belongs to technical field of forging, but particularly relate to the track switch mould of a kind of preheating, cooling and replacing core rod.
Background technology
At present, high speed railway construction has significant effects to the national economic development, and Develop High-Speed Railway needs high precision heavy rail.The last forging die and the anvil tool that are used to forge the rail switch mould in the prior art are an overall structure, each is processed by a module promptly to go up forging die and anvil tool, this kind structure interchangeability is poor, when the track switch shape and size of forging are close, then need to provide in addition mould, and when certain the local part in the mould was damaged, entire die was promptly scrapped, and causes the consumption and the serious waste phenomenon of mold materials.In addition, add man-hour in forging, because the temperature of mould itself is very big with forging processing temperature gap, and mold cavity surface and red-hot Metal Contact, cause the mold surface temperature can be up to 600-700 ℃, intensification causes mould distortion to occur easily rapidly so at short notice; And when red-hot metalwork taking-up, mould cools off rapidly, and the mold cavity surface is subjected to action of pulling stress, is prone to cracking etc., so shortened the service life of track switch mould.
Summary of the invention
But the present invention provides a kind of simple in structure, preheating, the cooling of being convenient to dismounting core rod and long service life and the track switch mould of changing core rod for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: but the track switch mould of preheating, cooling and replacing core rod, it is characterized in that: comprise upper bolster, die shoe and removable core rod piece, in upper bolster and die shoe, be embedded with core rod piece and fastening with it by set bolt, the upper bolster both sides are shaped on guide pin bushing, the corresponding upper bolster guide pin bushing of die shoe position is shaped on the guide pillar that is mated, also be shaped on the cooling hole on upper bolster and die shoe, described core rod piece is provided with bottoming hole.
The present invention can also adopt following technical scheme:
Described core rod piece is divided into upper mold core piece and lower mold core piece.
Described core rod piece comprises three station core rod pieces, and each station core rod piece constitutes by upper mold core piece and lower mold core piece.
Cooling hole on described upper bolster and the die shoe is a through hole.
In the bottoming hole on the described core rod piece heating element heater is housed.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, promptly three station core rods link to each other with die shoe with upper bolster respectively by the setting-in mode, when needs forge different size or difform track switch, can convenient and swift replacing core rod; Be provided with bottoming hole on core rod, preheating can be adopted the electric heater for heating mode, when using forging mold for the first time, mould can be preheated to 200-300 ℃, can avoid die deformation, and protect functional die effectively.Be shaped on the cooling hole on upper bolster and the die shoe, when mould frequently used intensification too high, logical water quench mould prevented that the mold cavity surface is subjected to action of pulling stress and cracking phenomena occurs, and then has prolonged the service life of track switch mould.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, upper bolster; 2, die shoe; 3, upper mold core piece; 4, lower mold core piece; 5, cooling hole; 6, bottoming hole; 7, guide pin bushing; 8, guide pillar; 9, set bolt; 10, survey hole of thermocouple.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, but the track switch mould of preheating, cooling and replacing core rod comprises upper bolster 1, die shoe 2 and removable core rod piece, described core rod piece is divided into upper mold core piece 3 and lower mold core piece 4.Described core rod piece comprises three station core rod pieces that are used to forge track switch, and each station core rod piece constitutes by upper mold core piece and lower mold core piece.Described upper mold core piece is inlaid in the upper bolster, and is fastening with it by set bolt 9.Lower mold core piece 4 is inlaid in the die shoe 2, and fastening by set bolt 9 and die shoe.The upper bolster both sides are provided with guide pin bushing 7, and the corresponding upper bolster guide pin bushing of die shoe position is provided with the guide pillar 8 that is mated, and described guide pillar is inserted in the guide pin bushing.Also be shaped on cooling hole 5 on upper bolster and die shoe, the cooling hole on described upper bolster and the die shoe is a through hole.Be equipped with bottoming hole 6 on described upper mold core piece and the lower mold core piece, heating element heater is housed in the bottoming hole.Be equipped with survey hole of thermocouple 10 on this external every upper mold core piece and the lower mold core piece, can realize detection by this hole to mold temperature, the more intuitive like this track switch mold temperature that demonstrates is so that can in time control the heating-up temperature and the chilling temperature of mould.
