Abstract
The utility model relates to a precision casting aluminum alloy device, in particular to a precision casting aluminum alloy pouring pressure-maintaining equipment. According to the technical scheme, the precision casting aluminum alloy pouring pressure-maintaining equipment comprises a pressure gauge, a supporting frame, a compressed air connecting-in end, a furnace door, a furnace body and a handle, wherein the supporting frame is arranged at the bottom of the furnace body, the compressed air connecting-in end and the pressure gauge are arranged at the top of the furnace body, the furnace door is arranged at one side of the furnace body, and the handle is arranged at the outer side of the furnace door. The precision casting aluminum alloy pouring pressure-maintaining equipment has the advantages of carrying out pressure-maintaining processing in the time when molten aluminum is fully solidified, preventing hydrogen from being separated out and gathering to form air holes under high air pressure, further meeting use requirements, solving technical problems, guaranteeing product quality, improving production efficiency, lowering production cost, and achieving cyclic utilization of waste equipment.
Description
Technical field
The utility model relates to a kind of aluminum alloy casting apparatus, particularly a kind of hot investment casting aluminium alloy cast pressurize equipment.
Background technology
Aluminium alloy air-breathing tendency of aluminium liquid in the hot investment casting fusion process is more serious, such aluminium alloy of China in essence casting process mainly by raw material stoving process, Argon refinery by de-gassing and avoid carrying out at wet weather the measure such as melting in the fusion process, it is qualified to guarantee to pour into a mould the rear surface pinhole rate.It is all higher that this kind technique uses equipment, smelting technology and weather to require to raw material processing procedure, melting, and wherein the words that go wrong of any point all can cause the product surface pin hole to occur.The product of having relatively high expectations for pinhole rate adopts the technique of vacuum-assist pouring-compression solidification, pours into a mould in the negative pressure still, can only pour into a mould one at every turn, and is high especially to equipment requirement, and production efficiency is very low.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of hot investment casting aluminium alloy cast pressurize equipment is provided.
Its technical scheme is: comprise Pressure gauge, bracing frame, compressed air incoming end, fire door, body of heater and handle, the bottom of body of heater is provided with bracing frame, the top of body of heater is provided with compressed air incoming end and Pressure gauge, and a side of body of heater is provided with fire door, and the fire door outside is provided with handle.
The beneficial effects of the utility model are: carry out pressurize and process within the time that aluminium liquid solidifies fully, be not gathered into pore so that hydrogen can not separated out from cast(ing) surface under higher air pressure, thereby satisfy instructions for use, solved technical problem; Guarantee product quality, enhanced productivity, reduced production costs, reached the recycling of used facilities.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is side views of the present utility model;
Among the upper figure: Pressure gauge 1, bracing frame 2, compressed air incoming end 3, fire door 4, body of heater 5, handle 6.
The specific embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises Pressure gauge 1, bracing frame 2, compressed air incoming end 3, fire door 4, body of heater 5 and handle 6, the bottom of body of heater 5 is provided with bracing frame 2, the top of body of heater 5 is provided with compressed air incoming end 3 and Pressure gauge 1, one side of body of heater 5 is provided with fire door 4, opposite side is connecting axle, fire door 4 outsides are provided with handle 6, place and can build a plane with dry refractory brick brick at bottom of furnace body for ease of formwork.
During use, with the aluminium alloy die head of model casting casting complete, (the common foundry goods time is no more than 5 minutes, and thick and large casting is no more than 10 minutes) puts into body of heater 5 within the shortest time, close fire door when the furnace cavity of body of heater 5 does not allow to put into formwork again, then internal pressurization is to 0.6MPa.For the thin-wall part dwell time more than 10min, the general wall thickness spare dwell time will reach 25-30min, the thick especially large foundry goods dwell time can extend to 1h.Open fire door after reaching the dwell time, formwork is picked out, after cooling off fully, formwork is cleared up.
