Abstract
A kind of vacuum melting anti-splash device, it is characterized in that: on vacuum furnace wall, be provided with sealing shroud, curved bar is provided with in sealing shroud, the inner of curved bar is provided with Splashproof cover, Splashproof cover is arranged with bimetallic pawl, be 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 be arranged on vacuum drying oven; Employing is arranged at the bimetallic pawl 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, molten metal after opening Splashproof cover injection melting, under the effect raised in molten die temperature when covering Splashproof cover again, bimetallic pawl just makes insulation cover and Splashproof cover unclamp, and is covered by insulation cover in time on fusible pattern mouth, effectively plays the double action of splashproof, insulation feeding in time, improve product quality from improving of equipment, reduce production cost.
Description
Technical field
The utility model relates to hot investment casting field, specifically 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 not only uneconomical, also no insulation feeding effect.
Summary of the invention
For above problem, the utility model provides a kind of vacuum melting anti-splash device, to improve the quality of products.
According to the technical scheme that the utility model provides, described vacuum melting anti-splash device, be included in the sealing shroud that vacuum furnace wall is arranged, curved bar is provided with in sealing shroud, the inner of curved bar is provided with Splashproof cover, and Splashproof cover is arranged with bimetallic pawl, is provided with dual insulation cover in bimetallic pawl, the outer end of curved bar is provided with connecting rod, and the lower end of connecting rod is connected with the pedal be arranged on vacuum drying oven.
The utility model adopts the sealing shroud be arranged in vacuum furnace wall to install curved bar, does not affect the vacuum of vacuum melting furnace; Employing is arranged at the pedal on vacuum drying oven and is connected with the lower end of connecting rod, makes Splashproof cover switching manipulation convenient; Employing is arranged at the bimetallic pawl 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, molten metal after opening Splashproof cover injection melting, under the effect raised in molten die temperature when covering Splashproof cover again, bimetallic pawl just makes insulation cover and Splashproof cover unclamp, and is covered by insulation cover in time on fusible pattern mouth, effectively plays the double action of splashproof, insulation feeding in time, improve product quality from improving of equipment, reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1, comprise 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 accompanying drawing, detailed description of the invention of the present utility model is further illustrated.
Shown in Fig. 1, the utility model 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 be arranged on vacuum drying oven.
The utility model employing is arranged at the pedal on vacuum drying oven and is connected with the lower end of connecting rod, makes Splashproof cover switching manipulation convenient; Employing is arranged at the bimetallic pawl 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, molten metal after opening Splashproof cover injection melting, under the effect raised in molten die temperature when covering Splashproof cover again, bimetallic pawl just makes insulation cover and Splashproof cover unclamp, and is covered by insulation cover in time on fusible pattern mouth, effectively plays the double action of splashproof, insulation feeding in time, improve product quality from improving of equipment, reduce production cost.
