Abstract
The utility model provides a low-voltage pouring resistance furnace which aims to solve problems that operators are easy to be scalded when taking liquid alloy from a crucible by the aid of a casting ladle and pouring quality is unstable. The low-voltage pouring resistance furnace is characterized in that a furnace cover is arranged on a protecting cover, a plurality of fastening bolts are arranged at the edges of the protecting cover and the furnace cover, and the furnace cover and the protecting cover are fastened together by the fastening bolts; two concentric sealing rings are arranged on a surface, which contacts with the furnace cover, of the protecting cover, wherein the small sealing ring is an asbestos heat-insulation sealing ring, and the large sealing ring is an airtight rubber sealing ring; a compressed air delivery pipe is arranged between a furnace body and the protecting cover, and the inner end of the compressed air delivery pipe leads to a furnace chamber; and the upper end of a riser tube is inserted and fixed on a circle center hole of the furnace cover. The low-voltage pouring resistance furnace has the advantages of simplicity and safety in operation and capability of remarkably increasing the quality of castings.
Description
Technical field
The utility model relates to a kind of low-pressure casting resistance furnace.
Background technology
Existing low-pressure casting resistance furnace comprises body of heater, crucible and protective cover, and pouring procedure is a molten alloy solution in crucible, treat that the solution melting is accomplished after, artificially contain out with casting ladle, directly pour into die cavity.Its defective is: in crucible, get alloy solution with casting ladle, scald easily.And be difficult to during cast hold poring rate and stability, uncontrollable because of poring rate, defectives such as the foundry goods slag inclusion of cast, pore are more, and casting density is poor, and processing performance is unstable, and percent defective is high.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of low-pressure casting resistance furnace that can avoid above-mentioned deficiency.
The purpose of the utility model is achieved in that it comprises body of heater, crucible and protective cover, is characterized in that: be bell above the protective cover, several fastening bolts that are used for the two is tightened together are arranged on the edge of protective cover and bell; The concentric sealing ring of two circles is set on the contact-making surface of protective cover and bell, and wherein ringlet is the asbestos insulation sealing ring, and great circle is the airtight rubber seal circle; The compressed gas appendix is arranged between body of heater and the protective cover, and the inner end of compressed gas appendix leads to furnace chamber; The upper end of stalk is inserted and secured on the bell circle center hole.Casting sand mold is placed on the bell, and die cavity is facing to circle center hole; In operating room, start the low-pressure casting machine, gas is imported in the stove by the compressed gas appendix, and solution in the stove is pressed into the casting sand mold die cavity by stalk, treat that solution is full of die cavity after, stop supercharging, pressurize, pressure release finish to fill the type casting process.
Compared with prior art, the good effect of the utility model is: change original pouring type, simple to operate, safety.Good seal, heat are difficult for running off.The low-pressure casting machine can expand to by the computer control poring rate, significantly improves the foundry goods casting quality, greatly reduces waste product.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
It comprises body of heater 1, crucible 2 and protective cover 7, is bell 4 above the protective cover, and several fastening bolts 3 that are used for the two is tightened together are arranged on the edge of protective cover and bell; The concentric sealing ring of two circles is set on the contact-making surface of protective cover and bell, and wherein ringlet is an asbestos insulation sealing ring 8, and great circle is an airtight rubber seal circle 9; Compressed gas appendix 10 is arranged between body of heater and the protective cover, and the inner end of compressed gas appendix leads to furnace chamber; The upper end of stalk 5 is inserted and secured on the bell circle center hole; The porose sealing gasket 6 in the center of circle is placed on the bell, and promptly sealing gasket 6 is placed between casting sand mold and the bell, can prevent that gas from leaking.Casting sand mold is placed on the sealing gasket, and die cavity is facing to circle center hole; In operating room, start the low-pressure casting machine, gas is imported in the stove by the compressed gas appendix, and solution in the stove is pressed into the casting sand mold die cavity by stalk, treat that solution is full of die cavity after, stop supercharging, pressurize, pressure release finish to fill the type casting process.
Claims (2)
