A kind of plastic mould matches mold technique, includes step a to e.
Step a, upper mold 7a and lower die 7b are steel, and upper mold 7a fusing point is higher than lower die 7b, and clamping element 3 installs upper mold 7a,
The inner bottom surface of material trough 1 installs lower die 7b.For plastic mould in mould, upper mold 7a has Product Process shape, and electric spark loses steel
Lower die 7b is processed technique shape possessed by upper mold 7a by mode, and upper mold 7a can cooperate with lower die 7b.It is lost using electric spark
The technology of steel, for lower die 7b corrosion molding during guarantee erosion steel, upper mold 7a geomery is stablized, and guarantees the fusing point of lower die 7b
Higher than upper mold 7a.
Lower die 7b is steel, and upper mold 7a selects steel as electrode material, and size is easy to control, and lower die 7b is anti-dandruff uniformly,
It is more stable to lose the resulting lower die 7b performance of steel.Match mould using electric spark steel erosion steel, the electrode in the traditional electric spark erosion steel of change is only
The habit of copper or graphite can be used.

The presence or absence of magnetism.
Step b injects working fluid in material trough 1, and the liquid level of working fluid is higher than 5~15mm of upper surface of lower die 7b, processing
Liquid is made of paraffin base oil, 1.7~2.3cst of viscosity of working fluid.Scale, the note sample height of working fluid is arranged in material trough 1
It is held, guarantee working fluid note sample enough and avoids wasting.
Step c, X-axis component 4 and the drive of Y-axis component 5 upper mold 7a are moved to the surface of lower die 7b, and Z shaft assembly 2 drives
Upper mold 7a is close to lower die 7b.The shaping position for selecting lower die 7b is selected, is driven according to the shaping position X-axis component 4 and Y-axis component 5
Upper mold 7a is moved to the surface of lower die 7b.In step c, when the following table face contact working fluid of upper mold 7a, according to lower die 7b's
Shaping position further adjusts the transverse direction and longitudinal direction position of upper mold 7a, and X-axis component 4 and Y-axis component 5 drive upper mold 7a mobile, protect
The shaping position for demonstrate,proving lower die 7b is corresponding with the technical face of upper mold 7a more acurrate.
Step d, when the lower surface of upper mold 7a is more than 3mm lower than liquid level, Power Supply Assembly is toward between upper mold 7a and lower die 7b
Start to export high-frequency pulse voltage, 20~200V of voltage, 500~1200Hz of frequency.The lower surface of upper mold 7a is more than lower than liquid level
When 3mm, working fluid floods the gap between upper mold 7a and lower die 7b, is powered at this time safer, and electric current is avoided to appear in processing
Liquid liquid level and cause fire and/or other accidents.In step b, upper surface 5 of the working fluid note sample liquid face higher than lower die 7b~
15mm, the then timing node that step d medium-high frequency voltage is initially powered up are relatively easy to hold.In step b and c, reduction of speed under upper mold 7a
Degree is less than 15mm/s；Between upper mold 7a and lower die 7b before making alive, upper mold 7a rapid decrease reduces process period.Voltage 20
~200V, 500~1200Hz of frequency guarantee to form sufficiently strong electric field between upper mold 7a and lower die 7b in step e, at power generation
It generates sufficiently large pressure and washes from the steel of corrosion quickly.

Road makes to generate electric field between upper mold 7a and lower die 7b, forms an ionization path and causes into arc column.Between lower die 7b and upper mold 7a
Gap forms ionization, and high-density current flows to lower die 7b whereby and generates, and generates 1800 DEG C~12000 DEG C of high temperature energy；When
When electric discharge continues, heat is continued growing at electric discharge, the upper epidermis fusing of lower die 7b.High temperature makes working fluid gasify, and at electric discharge
Enormous pressure is generated, the material of corrode is washed from electric discharge, the material at electric discharge is cooled down rapidly by the working fluid of surrounding again.Upper mold
7a continues close, electric discharge toward lower die 7b and continues, and the erosion steel loop section for losing steel and row's corrosion material recycles secondary many times, script surface
Concave-convex not positive mold obtains a smooth technical face.
Preferably, in step d and e, 50~120V of voltage, 800~1000Hz of frequency；In step e, upper mold 7a decrease speed
2~3.5um/s.Electric field strength is preferable between upper mold 7a and lower die 7b, and the pressure at electric discharge is enough and safe, lower die 7b upper epidermis
Steel corrosion speed and wash from that speed is preferable, the machined surface of lower die 7b is more smooth, precision is higher.
Preferably, in step d and e, 65~100V of voltage, 800~1000Hz of frequency；In step e, upper mold 7a is close to speed
Upper mold 7a stops close, high-frequency pulse voltage stopping when the gap of 2.4~2.8um/s, upper mold 7a and lower die 7b are 20~30um.
Clamping element 3 connects lower die 7b by cushion block 8, and 8 part of cushion block, which is worn, to be connect in clamping element 3, is provided on clamping element 3
For fixing the holding screw of cushion block 8.8 part of cushion block, which is worn, to be connect in clamping element 3, and holding screw abuts the outer of the part cushion block 8
Wall, holding screw are threadedly coupled with clamping element 3, so cushion block 8 is connected firmly with clamping element 3.Several be used for is provided on cushion block 8
It is bolted the mounting hole of upper mold 7a.Clamping element 3 connects upper mold 7a by cushion block 8, and clamping element 3 can be set as general shape
Formula, while clamping element 3 being avoided to be soaked in working fluid, 3 neat and tidy of clamping element, long service life reduces the cost exchanged.
Ultrasonic distance measurement component is connected on cushion block 8, ultrasonic distance measurement component includes ultrasonic wave transmitting part and ultrasonic wave
Receiving element, ultrasonic wave emits part and ultrasonic wave is received and is electrically connected with controller.Controller includes counting module, clock mould
Block, controller calculate distance by the transmitting-receiving time difference of ultrasonic wave, such as the height of the upper surface lower die 7b.Ultrasonic distance measurement group
Part is used to detect the height and/or working fluid liquid level of the upper surface lower die 7b；Upper mold 7a is standard component, has the height of calibration
And process structure, the gap between upper mold 7a and lower die 7b is determined by the height of the upper surface lower die 7b.
