Description
Technical field
The present invention relates to the rapid mould changing method of vacuum die casting machine liquid metal mold, in particular to liquid metal mold exists
Do not have to quickly change the mold in the case where lower die on vacuum die casting machine.
Background technique
Liquid metal mold is that metal is melt into liquid injection die cast into mold cavity, state metal by vacuum die casting machine
Because having high intensity, high rigidity, good toughness, the elastic limit of superelevation, wearability, corrosion resistance, unique acoustics and thermally conductive
Power receives heat ability and physical chemistry and mechanical property with brilliance, in consumer electronics, space flight, aviation, accurate machine
Tool, the fields of grade are widely used.
Liquid metal during evacuated die-casting process, liquid metal die casting be by high temperature, high pressure, etc. parameters in vacuum item
Die casting forms under part, so as to obtain the good casting of appearance.Liquid metal mold passes through high temperature, high pressure, high speed, Die Casting Condition
Under can cause erosion damage to mold cavity, for having an impact outside die casting after molding, the type chamber of erosion is repaired,
Replacement because of more mold exchange, enters son and takes a long time, and mold cooling, oil pumping need 15 minutes, lower mould needs 30 minutes,
It repairs a die and changes to son, mold will be dismantled, then machine needs 2 hours on assembly mold, therefore longer when mold changing.
Summary of the invention
The invention discloses a kind of rapid mould changing methods of liquid metal die casting, to solve prior art evacuated die-casting process
The die exchange of liquid metal mold is conventional die exchange, the problem of cannot quickly changing the mold.
The purpose of the present invention can be achieved through the following technical solutions.
A kind of liquid metal die casting, including the fixed half and moving half being mutually matched, the cover half includes fixed mold core；It is fixed
Mould enters son and enters in rim of the mouth from the front-installed fixed mold core of fixed mold core, and cover half is entered son from front locking by screw；Described is dynamic
Mould includes mavable module core；Dynamic model enters the sub automatic front-installed mavable module core of mode and enters in rim of the mouth, and dynamic model is entered son from just by screw
Face locking；The cover half enters son and dynamic model enters son and is set as circular conical surface or round table surface；The fixed mold core enters rim of the mouth, mavable module core
It is matching to enter rim of the mouth.
A kind of rapid mould changing method of liquid metal die casting, its step are as follows:
(1) die casting machine is shut down, the indoor vacuum of evacuated die-casting process is bled off；
(2) hatch door for opening die casting room, cover half, dynamic model are opened to range；
(3) turn off the power supply of die casting pump, preparation tool；
(4) mold repair personnel put on high temperature protection clothes with good high temperature gloves, into die casting room；
(5) cover half, the dynamic model on mould of die casting machine are entered son to remove；
(6) cover half is entered sub- loading fixed mold core to enter in rim of the mouth, cover half enters son and locks screw from front；
(7) dynamic model is entered sub- loading mavable module core to enter in rim of the mouth, dynamic model enters son and locks screw from front；Quickly mold changing is completed.
Technical solution of the present invention improves vacuum die casting machine with the switching of minimum down time difference mold time, maximum
Mobility, can be mold quickly more as long as being operated inside vacuum die casting machine progress in the case that mold does not have to lower machine
It changes.Liquid metal mold design structure is different with other mold design structures, liquid metal mold mold in process of production
It is easy erosion, so the type chamber of each product is repaired a die in this way in such a way that line is cut into son when design mould structure
When can accomplish into sub- switching.
The invention has the following advantages: 1. optimize mould inside structure.2. reducing the operation stream of mould inside
Journey.3. optimizing mold exterior operation.4. shortening original mold mould replacing time.Farthest improve vacuum die casting machine
Utilization rate.
Detailed description of the invention
Fig. 1 is fixed mold core structural schematic diagram of the invention；
Fig. 2 is the cross section structure schematic diagram of mavable module core；(save cover half and enter son)
Fig. 3 is mavable module core structural schematic diagram of the invention；
The cross section structure schematic diagram of the position Fig. 4 fixed mold core；(save dynamic model and enter son)
In figure, 1, fixed mold core 2, cover half enter son 3, fixed mold core enters sub-aperture 4, mavable module core 5, dynamic model and enters sub 6, mavable module core
Enter sub-aperture.
Specific embodiment
Technical characterstic of the invention is further illustrated with specific example with reference to the accompanying drawing.
A kind of liquid metal die casting as Figure 1-Figure 4, including the fixed half and moving half being mutually matched, described determines
Mould includes fixed mold core 1；The cover half enters son 2 and enters in rim of the mouth 3 from the front-installed fixed mold core of fixed mold core 1, and will be determined by screw
Mould enters son 2 from front locking；The dynamic model includes mavable module core 4；Dynamic model enters the sub 5 front-installed mavable module cores of automatic mode 4 and enters son
In mouth 6, and dynamic model is entered from front locking by son 5 by screw；It is circular conical surface or circle that the cover half, which enters son 2 and enters son 5 with dynamic model,
Table top；It is matching that the fixed mold core enters rim of the mouth 3, mavable module core enters rim of the mouth 6.
A kind of rapid mould changing method of liquid metal die casting, its step are as follows:
(1) die casting machine is shut down, the indoor vacuum of evacuated die-casting process is bled off；
(2) hatch door for opening die casting room, cover half, dynamic model are opened to range；
(3) turn off the power supply of die casting pump, preparation tool；
(4) mold repair personnel put on high temperature protection clothes with good high temperature gloves, into die casting room；
(5) cover half, the dynamic model on mould of die casting machine are entered son to remove；
(6) cover half is entered sub- loading fixed mold core to enter in rim of the mouth, cover half enters son and locks screw from front；
(7) dynamic model is entered sub- loading mavable module core to enter in rim of the mouth, dynamic model enters son and locks screw from front；Quickly mold changing is completed.
Cover half enter son it is front-installed from fixed mold core, surrounding does gradient, from front lock screw, be conducive to fast assembling-disassembling in this way.
Dynamic model as fixed mould structure, cover half enter son it is front-installed from fixed mold core, surrounding does gradient, from front lock screw, it is advantageous in this way
In fast assembling-disassembling.Mold enters son, accessory will accomplish unified standardization, and mould structure will optimize as far as possible, is just able to achieve so quickly
Method.
