Abstract
The utility model relates to a multi-cavity low-pressure casting press vane wheel device, which is characterized by employing multiple liquid lifting tubes in a crucible, arranging stainless steel filter screens on openings of the lifting tubes, mounting gypsum mould anti-spilt protecting sleeves on the stainless steel filter screens, installing gypsum moulds inside the gypsum mould anti-spilt protecting sleeves, covering light alloy casting cover plates on gypsum moulds, connecting pressing plates to the upper portion of the light alloy casting cover plates and wrapping heat barrier materials and protecting sheaths with thick sandwich layers surrounding furnaces. The utility model with reasonable design has the advantages of reducing physical output of workers caused by standing thermal radiation as a result of saving electricity and insulating heat, shortening working time of casting aluminum liquids due to high production efficiency, decreasing rate of spoiled with inclusion and dust due to utilization of the stainless steel filter screens and guaranteeing chemical composition, metallographic structure and physical properties of vane wheels with the light alloy cover plates.
Description
Technical field
The utility model relates to a kind of a multi-cavity mold low pressure casting and presses impeller device, and especially a kind of equipment that is used for low pressure casting booster pressure impeller belongs to casting technology field.
Background technology
In prior art, the low pressure casting aluminum alloy compressor impeller normally adopts the forging type in a mould one chamber, this kind mode yield is low, the electric heating utilization rate is low, and labor strength is big, lacks safety prevention measure, particularly the filtration of aluminium liquid is not in place, the alumiaum article crystallization is thick, and it is many to be mingled with ash, the quality instability.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and providing a kind of can enhance productivity, and shortens the casting working time of aluminium liquid; Can reduce the percent defective that is mingled with ash; And can guarantee the chemical analysis of impeller and a multi-cavity mold low pressure casting pressure impeller device of structure and physical property.
According to the technical scheme that the utility model provides, a multi-cavity mold low pressure casting is pressed impeller device, adopts and be provided with seal cover board on the crucible in electrothermal furnace, and feature is: be provided with a plurality of stalks in the crucible; There is compressed gas (or indifferent gas) pipe to feed in the crucible; on the stalk mouth, place stainless steel filtering net; place plaster mold anticracking protective sleeve on the stainless steel filtering net; plaster mold places in the plaster mold anticracking protective sleeve; light-alloy casting cover plate is stamped in the plaster mold top, and light-alloy casting cover plate top connects pressing plate.
Safty shield is stamped in the utility model entire equipment top, and heat-insulating shield is connected with safty shield; Described electrothermal furnace periphery is surrounded by the abundant heat-barrier material of interlayer, and heat-barrier material is provided with heat-insulating shield outward; Described plaster mold is in advance through preheating in the baking oven of heating, and the baking oven of heating is lifted voluntarily and put down by the pneumatic hoist that is installed on its below.
The utility model scientific structure design is reasonable, and power saving is heat insulation; Can reduce the physical demands that the workman causes because of thermal radiation; And the production efficiency height can shorten casting working time of aluminium liquid; Owing to adopted stainless steel filtering net, reduced the percent defective that is mingled with ash again; The use integral body of light-alloy cover plate has been guaranteed chemical analysis and the structure and the physical property of impeller.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, comprise stainless steel filtering net 1, stalk 2, plaster mold 3, anticracking protective sleeve 6, light-alloy casting cover plate 7, safty shield 8, heat-barrier material 9, pressing plate 10, compression gas pipe 11, crucible 12, electrothermal furnace 13, heat-insulating shield 14 and crucible seal cover board 15 etc.
Crucible is provided with crucible seal cover board 15 in the electrothermal furnace 13, and crucible 12 is positioned at electrothermal furnace 13, is provided with a plurality of stalks 2 in the crucible 12, and compressed gas (or indifferent gas) pipe 11 feeds in the crucible 12; Place stainless steel filtering net 1 on 2 mouthfuls of stalks, place plaster mold anticracking protective sleeve 6 on the stainless steel filtering net 1, plaster mold 3 places in the plaster mold anticracking protective sleeve 6, and light-alloy casting cover plate 7 is stamped in plaster mold 3 tops, and light-alloy casting cover plate 7 tops connect pressing plate 10.Described electrothermal furnace 13 peripheries are surrounded by the abundant heat-barrier material of interlayer 9, the heat-barrier material 9 outer heat-insulating shields 14 that are provided with.
We replace original thicker mineral wool fiber filter screen to be placed on above 2 mouthfuls of the stalks with very thin stainless steel filtering net 1; then plaster mold 3 is taken out in the small bake oven 4 of the preheating of heating; put into the plaster mold anticracking protective sleeve 6 on the stalk; cover light-alloy casting cover plate 7 and clamping platen 10, put down safty shield 8 at last.By compression gas pipe 11 compressed air or inert gas are pressed into the aluminium liquid in the crucible 12 in the combination die in each gypsum die cavity simultaneously, casting so far presses the impeller process to finish.
Whole electrothermal furnace 13 peripheral abundant heat-barrier material 9 of interlayer and the heat-insulating shields 14 used are protected, and can prevent that heat from distributing.
