Abstract
A kind of vacuum melting anti-splash device, it is characterized in that: on vacuum furnace wall, be provided with sealing shroud, sealing shroud is provided with curved bar, it is provided with Splashproof cover on the inner of curved bar, Splashproof cover is arranged with bimetallic pawl, being provided with dual insulation cover in bimetallic pawl, the outer end of curved bar is provided with connecting rod, the lower end of connecting rod is connected with the pedal being arranged on vacuum drying oven；Use the bimetallic pawl being arranged under Splashproof cover, can press into insulation cover during cold conditions；When vacuum melting, cover Splashproof cover and play the effect preventing impurity to be splashed into fusible pattern mouth, when opening the molten metal after Splashproof cover injects melting, when covering Splashproof cover again under the effect that molten die temperature raises, bimetallic pawl just makes insulation cover unclamp with Splashproof cover, is covered in time on fusible pattern mouth by insulation cover, effectively plays splashproof, the dual function of insulation feeding in time, improve product quality from improving of equipment, reduce production cost.
Description
Technical field
The present invention relates to hot investment casting field, a kind of vacuum melting anti-splash device.
Background technology
Precision-investment casting needs to use vacuum melting furnace, but in Vacuum Melting, the impurity sputtered can be splashed in fusible pattern cast gate often, has a strong impact on the qualification rate of product, and conventional metal film covering method is the most uneconomical, also no insulation feeding effect.
Summary of the invention
For problem above, the present invention provides a kind of vacuum melting anti-splash device, to improve product quality.
The technical scheme provided according to the present invention, described vacuum melting anti-splash device, it is included on vacuum furnace wall the sealing shroud arranged, sealing shroud is provided with curved bar, being provided with Splashproof cover on the inner of curved bar, Splashproof cover is arranged with bimetallic pawl, is provided with dual insulation cover in bimetallic pawl, being provided with connecting rod on the outer end of curved bar, the lower end of connecting rod is connected with the pedal being arranged on vacuum drying oven.
The present invention uses the sealing shroud being arranged in vacuum furnace wall to install curved bar, does not affect the vacuum of vacuum melting furnace；Use the pedal being arranged on vacuum drying oven to be connected with the lower end of connecting rod, make Splashproof cover switching manipulation convenient；Use the bimetallic pawl being arranged under Splashproof cover, can press into insulation cover during cold conditions；When vacuum melting, cover Splashproof cover and play the effect preventing impurity to be splashed into fusible pattern mouth, when opening the molten metal after Splashproof cover injects melting, when covering Splashproof cover again under the effect that molten die temperature raises, bimetallic pawl just makes insulation cover unclamp with Splashproof cover, is covered in time on fusible pattern mouth by insulation cover, effectively plays splashproof, the dual function of insulation feeding in time, improve product quality from improving of equipment, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In Fig. 1, including vacuum furnace wall 1, sealing shroud 2, curved bar 3, connecting rod 4, pedal 5, Splashproof cover 6, insulation cover 7, bimetallic pawl 8, fusible pattern mouth 9 etc..
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is further illustrated.
Shown in Fig. 1, the present invention is a kind of vacuum melting anti-splash device, sealing shroud 2 is arranged at the side on vacuum furnace wall 1, curved bar 3 is arranged in sealing shroud 2, Splashproof cover 6 is arranged on the inner of curved bar 3, and bimetallic pawl 8 is connected to Splashproof cover 6 times, and insulation cover 7 is arranged in bimetallic pawl 8, the upper end of connecting rod 4 is connected with the outer end of curved bar 3, and the lower end of connecting rod 4 is connected with the pedal 5 being arranged on vacuum drying oven.
The present invention uses the pedal being arranged on vacuum drying oven to be connected with the lower end of connecting rod, makes Splashproof cover switching manipulation convenient；Use the bimetallic pawl being arranged under Splashproof cover, can press into insulation cover during cold conditions；When vacuum melting, cover Splashproof cover and play the effect preventing impurity to be splashed into fusible pattern mouth, when opening the molten metal after Splashproof cover injects melting, when covering Splashproof cover again under the effect that molten die temperature raises, bimetallic pawl just makes insulation cover unclamp with Splashproof cover, is covered in time on fusible pattern mouth by insulation cover, effectively plays splashproof, the dual function of insulation feeding in time, improve product quality from improving of equipment, reduce production cost.
