Rate, while also substantially increasing the quality of product.
Brief description of the drawings
Fig. 1 carries out view during malleation detection for the EPS sheet material machine cavity pressure detection means of the present invention.
Fig. 2 carries out view during detection of negative pressure for the EPS sheet material machine cavity pressure detection means of the present invention.
Embodiment
Present pre-ferred embodiments are provided below in conjunction with the accompanying drawings, to describe technical scheme in detail.
EPS sheet material machine cavity pressure detection means of the invention as depicted in figs. 1 and 2, including it is cylinder body 1, piston 2, close
Seal washer 3, swivel nut 8, taper washer 5, valve element 6, spring 7, screw rod 9 and holding screw 11, the nesting of cylinder body 1 are fixed on EPS sheet material
In machine die cavity wall, piston 2 be arranged on the inside of cylinder body 1 and with EPS sheet material machine mould cavity, the inside of piston 2 is provided with through hole, piston 2
Front end is provided with seal washer 3, and the inside of seal washer 3 is connected provided with through hole and with the through hole inside piston 2, EPS sheet material machine mould
Cavity wall 100 is provided with through hole, and the side of cylinder body 1 is provided with holding screw 11, and the inside of holding screw 11 is provided with through hole, holding screw 11
The through hole in portion is connected with the through hole on the through hole inside piston 2 and EPS sheet material machine die cavity wall 100 respectively, and the front end of cylinder body 1 is provided with
Swivel nut 8, one end of swivel nut 8 is arranged on cylinder body 1, and the other end is provided with inside screw rod 9, swivel nut and is sequentially provided with taper washer 5, valve element 6
With spring 7, the through hole inside taper washer 5 is connected with the interior bone of seal washer 3, and valve element 6 has the conical surface and its conical surface is supported
On the conical surface of taper washer 5, the two ends of spring 7 are against on valve element 6 and screw rod 9 respectively, and the inside of screw rod 9 is provided with through hole and connects pressure
Contracting air intake duct 200；The front end of cylinder body 1 is additionally provided with venthole and connects pressure detecting pipeline 300, pressure detecting pipeline 300
Electro connecting pressure gauge, the venthole of the front end of cylinder body 1 and the through hole of seal washer 3 are provided with, in addition, being set between cylinder body 1 and piston 2
There is O-ring 4, the front end outer side of cylinder body 1 is additionally provided with sleeve 10, and seal washer 3 is provided with the inclined hole communicated with its interior bone.Connect in figure
Continuous arrow show pressure direction.
Because EPS sheet material machine is when heating, EPS particles expanded by heating in die cavity, so when piston is by die cavity
In EPS particle expansion power when, can be toward returning back to top, pressure P can open valve element top if reaching certain value, valve element and taper washer
The conical surface between have gap, at this moment the pressure of compressed air can be sent to electro connecting pressure gauge by compressed air by gap,
Some pressure falls the counteracted by pressure from die cavity simultaneously, and at this moment pressure gauge detection is malleation；
When vacuum system takes out negative pressure to EPS sheet material machine die cavity, the negative pressure in die cavity, by the through hole on aluminium sheet,
By the through hole on holding screw, by the through hole on piston, by the through hole on seal washer, until electric contact pressure
Table, at this moment pressure gauge detection is negative pressure.
Using the pressure sensitive device of the present invention, after the time, charging terminated, program can take out to EPS sheet material machine die cavity automatically
Negative pressure so that the gap between EPS particles and particle in EPS sheet material machine die cavity is compacter；If the electric contact that outside connects
Pressure gauge negative pressure is not set up, and illustrates that the material in EPS sheet material machine is not filled it up with, and die cavity is also to turn on the external world.Such journey
Sequence will again feed to EPS sheet material machine, can also equally be set in secondary charging time-program(me), the secondary charging time
After end, program can also take out negative pressure to EPS sheet material machine die cavity, so circulate, set up until die cavity negative pressure, (generally only
Need secondary charging just can be with).At this moment illustrate that the material of EPS sheet material machine die cavity is filled it up with, but also ensure in die cavity EPS particles it
Between gap also very little.The EPS sheet made also must be square-folded, particularly on angle, before being not in like that, because
Charging is discontented and situations such as unfilled corner.
In vacuum cooled link, it is not required that be manually set cool time processed, but detected according to pressure sensitive device
Negative pressure value, negative pressure value finishes once to cooling, carries out next link.Because during early stage is heated, in die cavity
There are the pressure of steam, the expansive force that EPS particles by heat is produced, so the pressure in die cavity is very high, it is necessary to which vacuum system is to die cavity
Negative pressure is taken out, quickly heat is all taken out, until electro connecting pressure gauge to the negative pressure value of setting.
