Description
Technical field
The present invention relates to a kind of compound semisolid die forging die device.
Background technology
Fixture block part 4 is the connector of conventional fixing wire on high-voltage switch gear, as Figure 1-3, fixture block part 4 surface
There are multiple curved surfaces（1、2、3）, due to working under the conditions of extra-high voltage, for preventing point discharge, must be smooth between each surface
Transition, requires fixture block part 4 to have higher material corrosion resistance and higher mechanical property simultaneously.
Conventional fixture block part material used for high-voltage switch is aluminium alloy, and at present, fixture block part adopts casting method to become mostly
Type, be then machined out, drilling and tapping and follow-up heat treatment to obtain final products, inherently scarce due to mo(u)lded piece
Fall into, lead to the fixture block part strength of casting relatively low, the easy running of screw thread, the stability of impact high-tension circuit.For improving folder
The performance of block part, by using forging method carry out manufacture produce, but forging method can only a mould single-piece production, effect
Rate is relatively low, and needs larger pressure, tonnage of equipment etc. is required higher, input cost is larger.
And the low pressure casting of routine, one as disclosed in the Chinese utility model patent that Authorization Notice No. is CN 2569950 Y
Plant anti-oxidation magnesium alloy low-pressure die-casting machine, including holding furnace, die device and stalk, will be protected using pulsometer aborning
Molten metal in warm stove is pressed in the die cavity of die device, carries out pressurize for a period of time simultaneously, treats that the molten metal in die cavity coagulates
Gu after, then discharge pressure and so that the not solidified molten metal in stalk is back in holding furnace, and long pressure repeatedly is big
The big service life reducing holding furnace, because, in pressure maintaining period, the precise control of air pressure is relatively difficult, is easily caused batch production
When each batch between unstable product quality.And, the pressure of low-pressure casting process low it is difficult to eliminate cast sturcture, make casting
The mechanical property of part reduces.

Mold, lower mold apparatus include the lower mould with lower mode cavity corresponding with each upper cavity, and upper cavity is closed with corresponding lower mode cavity
Form die cavity, upper mould device up or down die device is provided with the passage for connecting holding furnace and each die cavity, described passage after mould
It is provided with the check valve entering each die cavity for molten metal.
Described passage includes vertical stalk running channel corresponding with each die cavity with the liquid outlet connecting stalk, stalk
There is the inlet connecting with holding furnace, check valve includes the valve element of the liquid outlet for blocking stalk.
Described die cavity has more than three and the radial direction along stalk is radially distributed.
Connection is provided with the position corresponding to the thermal center position of each part to be produced on described upper mould device corresponding
The extrusion chamber of upper cavity, can move up and down in extrusion chamber and be coated with pressure ram, and pressure ram moves up to maximum with respect to upper mould
During displacement, the extrusion chamber below pressure ram forms the feeding space carrying out feeding for the thermal center position treating manufactured parts.
There is between described pressure ram and extrusion chamber the gap that can discharge for the gas in upper cavity, lower mode cavity.
Described upper mould device also includes upper bolster, and upper bolster has the vertically extending cavity of axis, described cavity
In up and down guiding movement be provided with for pressure ram hard-wired pressure ram mounting blocks, stalk is arranged on lower mold apparatus.
It is provided with stage clip between described pressure ram mounting blocks and mold.
It is provided with coldplate between described upper bolster and mold, upper coldplate is provided with for cooling flow of media
