Description
Technical field
The present invention relates to the hot-working process of metal material, relate to the technology equipment of the cast form of high-abrasive material medium, specifically, relate to a kind of rising head and casting mold cavity integrated molding mould.
Background technology
Along with the technical merit of melting and casting industry improves constantly, considerable part mechanization or intelligent production line progressively are applied to the melting and casting industry, replace manual work.Especially in the Foundry Production mode of horizontal parting, the dead head technology still is in the handwork level stage, has seriously restricted the development of mechanization or intelligent production line.
Dead head is one of requisite technique of melting and casting.In the melting and casting industry, dead head is made the common several manufacture methods that adopt of moulding and is at present:
1, adopt damp film sand by easy wooden model or metal mould forming, damage is large.
2, adopt water-glass sand to realize the dead head moulding by easy wooden model or metal die, or by back-up sand moulding in metal mold dead head mould bases, need to be to the heating of dead head sand mold or baking-curing moulding.
3, adopt resin sand to realize the dead head moulding by metal die, or, by back-up sand moulding in metal mold dead head mould bases, in forming process, constantly heat it is solidified.In order to realize the dead head moulding, need to add separately a core shooter, its dead head mould structure complexity, the comprehensive method of investment is large.
Above-mentioned several dead head is made, and workload is large, more needs to shift to an earlier date prefabricated and stores, and during use, need to install one by one.In carrying, installation process, be easy to cause the damage of dead head to have waste, during installation, more easily produce a large amount of loose sands, must carry out necessary cleaning, take time and effort, particularly the loose sand cleaning is not thorough, during cast, can be brought into running gate system by molten metal, directly affects the cast article quality.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of rising head and casting mold cavity integrated molding are provided, overcome the rising head carrying and the defect that exists is installed, time saving and energy saving, cost is lower, and can guarantee rising head and the casting mold cavity integrated molding mould of cast article quality.
To achieve these goals, the technical solution used in the present invention is:
This rising head and casting mold cavity integrated molding mould, comprise that core shooter, casting mould patrix reach and the forming panel of casting mould patrix mould assembling, the penetrating to chew with the core shooting hole of casting mould patrix of described core shooter is connected, also comprise the rising head molding sleeve that is located on described casting mould patrix, on described rising head molding sleeve top, be provided with end cap; On described casting mould patrix, establish the nib that communicates with described rising head molding sleeve trepanning; Also comprise and be located at the upper core in described trepanning and be located at the lower core on described forming panel, described upper core top stretch out described end cap and be fixed on core shooter to penetrate head upper, described upper core bottom and described lower core top are stretched into respectively in nib or trepanning and are connected.
On the end face of core bottom, be provided with detent on described, on described lower core top, establish the positioning step that matches with described detent, the docking that matches with positioning step by detent of described upper core and lower core.
Described lower core is not less than with the area of the butt end of upper core docking the contact-making surface that described lower core contacts with described upper core.
Described nib is located at the center of described casting mould patrix, and the center line of described rising head molding sleeve, described casting mould patrix, described upper core and described lower core overlaps.
Described upper core inner is cavity structure, and the core bottom center is provided with the aperture that reduces self temperature distortion on described.
On described rising head molding sleeve, reach described Xia Xin center and be equipped with bottoming hole, in described bottoming hole, be provided with electrothermal tube.
On described end cap, be provided with air discharge duct; Described air discharge duct is uniformly distributed on the end cap circumference; On the air discharge duct of described end cap or described end cap, be provided with venting plug.
Penetrating on head of described core shooter, be provided with groove, described upper core top is fixed in described groove by locking nut.
Described end cap with described rising head molding sleeve, be structure as a whole or described end cap with together with described upper core, be fixed on core shooter penetrate that head is upper or described end cap is structure as a whole with described rising head molding sleeve and end cap is fixed on penetrating on head of core shooter together with described upper core.
Cavity between described upper core and lower core and described trepanning and nib forms rising head moulding die cavity.
The invention has the advantages that: this rising head and casting mold cavity integrated molding mould, at first, rising head and casting mold cavity integrated molding, when cast article, do not need to install separately rising head like this, just do not need carrying and rising head is installed, and can not cause damage to rising head; Simultaneously can not produce loose sand, not only save the loose sand clearance time, time saving and energy saving, can avoid the impact of loose sand on cast article simultaneously, guarantee the cast article quality.
Secondly, rising head and casting mold cavity integrated molding, only need to use the core shooter of casting mold cavity originally to realize, can save cost.
Secondly, rising head molding sleeve and upper core can be realized the machine automatization equalization with docking of lower core again, when reducing hand labor intensity, can greatly enhance productivity.
Finally, this mould, realize rising head and the moulding of casting mold cavity synchronous integrated, the two synchronous heat curing molding, and process is easy, has omitted carrying, the installation of dead head, directly reduces recruitment, reduces the recruitment cost; And its can meet under heated condition work or the normal temperature state under cold forming work.
