Description

A kind of hydraulic wedge mechanism of counter-pressure casting machine

Technical field

The invention belongs to Casting Equipment technical fields, more particularly, to a kind of difference using Counter-gravity Mould Filling, High Pressure Solidification The hydraulic wedge mechanism of pressure casting machine.

Background technique

Differential air pressure casting method is the casting new method to grow up the beginning of the sixties, have concurrently low pressure casting and autoclave pressure casting it is excellent Point.There is obviously advantage in large size, complexity, thin-walled, precision, the production of high-quality high strength light alloy-steel casting.Differential pressure casting Make is added with seal closure outside casting mold, to cover interior compressed air suits on the basis of low-pressure die casting plant, casting mold is made to be in certain Under pressure.When liquid metal filling, make gas in holding furnace pressure be greater than casting mold in gas pressure, when as low pressure casting that Sample realization molten metal fills type, pressure maintaining and pressurization, but casting is higher under seal closure and autoclave pressure bidirection press at this time Pressure act on lower crystallization and freezing, obtain the higher casting of consistency so can guarantee.During counter-pressure casting, holding furnace gold Belonging to the scheme that on liquid level and casting mold internal pressure differences obtain has supercharge method and two kinds of decompression method, wherein supercharge method be first to seal closure and The gas of same pressure is passed through in holding furnace simultaneously, makes pressure balance.Then the gas pressure value in seal closure, Xiang Baowen are kept It is gradually passed through the bigger gas of pressure in furnace on metal bath surface, creates the pressure difference of tank up and down, so that realizes molten metal fills type And pressure maintaining.And depressurizing method is first into seal closure and holding furnace while to be passed through the gas of same pressure, after equilibration had been achieved, gradually The compressed gas in seal closure is put, is that pressure gradually reduces, that realizes molten metal fills type and pressure maintaining.

Counter-pressure casting is on the basis of low pressure casting, added with seal closure outside casting mold, while into cover and in holding furnace It is passed through the compressed gas of controllable pressure, is in casting mold under certain pressure, molten metal is filled to casting mold under the action of pressure difference In, a kind of process for being crystallized, being solidified and obtained casting.Compared to low pressure casting, casting obtained by counter-pressure casting is more caused Close, casting tensile strength can be improved 10~50%.But since in counter-pressure casting cavity filling process, the back-pressure of casting mold type chamber is larger, because And complicated thin-wall part is not easily molded, is easy to fill the casting of type and the longer heavy wall of setting time or mean wall thickness suitable for producing Part, while the dimensional profile of casting is limited by upper pressure chamber diameter, is suitable for producing middle-size and small-size.

In modern production, as the quality requirements to casting are higher and higher, counter-pressure casting Processes and apparatus is also required Need to constantly improve update.Current counter-pressure casting machine, it is complete not enough for the specific forging type of certain complex-shaped casting It is kind, and traditional counter-pressure casting machine the degree of automation and safety be not high, it is difficult to it realizes high production efficiency and guarantees that casting is high The quality of production, and then largely effect on the yield rate and production cost of casting.

Summary of the invention

In order to solve the above technical problems, the present invention provides a kind of counter-pressure castings using Counter-gravity Mould Filling, High Pressure Solidification The hydraulic wedge mechanism of machine.

A kind of hydraulic wedge mechanism of counter-pressure casting machine of the invention assists master cylinder to generate mold clamping force, packet to mode locking Include hydraulic slider wedge, upper hydraulic wedge and lower hydraulic wedge, hydraulic slider wedge is located on the downside of upper plate, and there are upper hydraulic wedge in two sides, under it is hydraulic Wedge is located at column upper section, and lower rod end and movable plate are rigidly connected, and pillar side is equipped with locked groove, when mode-lock status, upper hydraulic wedge It is driven by hydraulic slider wedge and is bonded with lower hydraulic wedge, seal pillar data feedback channel；Lower rod end and movable plate are rigidly connected, thus It prevents autoclave pressure and mold from opening, realizes mode locking；Safety lock head is drawn back by cylinder under working condition, does not interfere pillar to move, Off working state cylinder stretches out, and safety lock head is inserted into pillar side locked groove, prevents pillar downslide from movable plate being caused to fall extremely.

Counter-pressure casting machine of the present invention compared with the existing technology the advantages of be: use reasonable, compact structure, and combine it is cold But system and control system realize the full-automatic production of counter-pressure casting.Hydraulic slider wedge, upper hydraulic wedge and under hydraulic wedge shape Molding and mode locking effect are realized well at hydraulic wedge structure, improve production efficiency.Unloading mechanism can be according to different casting It realizes a variety of material returned strokes, improves applicability.Middle partition retaining mechanism improves safety, and locking effect is good, flexible form. Pneumatic metal bath transport packet improves the safety of molten aluminum transportational process.
