Wet base product dehydration mould assembly and the plant fiber plastic suction forming apparatus skill with the assembly disclosed in present patent application
Art scheme before realizing the molding discharging of fiber pulp adsorption mould, wet base plastics sucking moulding is completed in molding machine and wet base free water is de-
Except operation, the subsequent drying process pressure of wet base, energy can be greatly reduced in novel wet base product dehydration mould assembly and molding machine
Source consumption, shortens the dry used time, substantially reduces plastic uptake finished product manufacturing process, improves product scale manufacturing efficiency, also drop
The low either cost consumption of natural seasoning or high-temperature oven drying method.In addition to this, the technical program also has following prominent
Technological merit out: 1, wet base product free water removal, the work are implemented in wet base product dehydration mould assembly and the cooperation of adsorption forming mould
Industry method combines density between improving fiber, improves the intensity of plastic uptake finished product；2, because dewatered wet base products thickness more connects
It is bordering on finished product thickness requirement, is easier to control quality of finished by technical requirement in forming process, makes up to design skill
The requirement of art index accuracy；3, it overcomes and directly dries or spontaneously dry processing method after existing forming method pulp and collapse, collapse
With the appearance of internal capillary hole phenomenon, finished surface free of bark shape fold, internal density is uniform, product shape is smooth, beautiful；4,
Free water in wet base product squeeze it is de- after, airtight film is also detached from dewatered wet base under the action of negative pressure immediately, between wet base
With apparent interval, it is broken to avoid the wet base that the touching friction that existing plastic suction forming apparatus divides in Mo Shiyin relative movement is caused
Technical problem is damaged, therefore, the technical program is more convenient for designing and manufacturing the higher fiber pulp plastics suction mould of demoulding verticality requirement
And its product, product category can be widened significantly, and product quality also greatly improves.

Specific embodiment
The wet base product that present patent application provides is dehydrated mould assembly, as shown in Figure 1, its composition includes die body 1 and airtight film
2.The die body 1 has die face 10 in profile corresponding with the molding of the mould surface bumps of plastics sucking moulding mould assembly B, airtight film 2
Be made of soft resilient material, such as silica gel, flexible rubber, coincide be covered in the profile of die body 1 in die face 10, edge with
1 air-tight fit of die body.To cast a brick to attract jade, Fig. 4,5 give one implementation knot of airtight film 2 and the assembly of the detachable air-tight fit of die body 1
Structure.It include edge press box 7 in the structure, the edge press box 7 and 2 edge of airtight film are in the same size, edge press box 7 and mould
The male-female card slot 8 for withholding airtight film is equipped between 1 peripheral lip of body, airtight film 2 is matched in edge press box 7 and 1 card slot 8 of die body
Pressed in conjunction, and fixed by screw 9, it is ensured that the air-tightness at airtight film 2 edge and die body 1.
In die body 1, gas chamber 3 is equipped in profile on the inside of die face 10, gas chamber 3 leads to die face 10 in profile and is equipped with several air flues 4.
The connection of gas control unit is connected to setting with gas chamber 3.The gas control unit includes pressurization gas circuit composition 5 and its air delivery valve 15 and true
Air road composition 6 and its vacuum valve 16.When vacuum valve 16 is closed, air delivery valve 15 is opened, the compressed air being filled in gas chamber 3, and
Top airtight film 2 is filled by air flue 4, expands airtight film 2 outward, is squeezed using its bulbs of pressure wet on plastics sucking moulding mould assembly B
Base removes wet base free water；When vacuum valve 16 is opened, air delivery valve 15 is closed, gas chamber 3 is in negative pressure, and airtight film 2 is immediately from expansion
State is fitted in profile in die face 10 from new covering, is separated with wet base.
Plastic uptake dehydration mold forming method disclosed in the present application is realized by plant fiber plastic suction forming apparatus.This plant fiber plastic uptake
Shaping machine set installing is equipped with above-mentioned wet base product dehydration mould assembly A, includes the longitudinal rail along shaping station M in complete machine composition
It is squeezed above the plastics sucking moulding mould assembly B of 11 operations, plastics sucking moulding mould assembly B, along the wet base product that horizontal guide rail 12 is run de-
Water mould assembly A and transfer mould assembly C, 12 width of horizontal guide rail is across forming outer station L, shaping station M and blanking station
N.It is equipped on the horizontal guide rail 12 of this complete machine in shaping station outer stroke switch, shaping station travel switch and blanking station row
Cheng Kaiguan, does not show that each travel switch position in figure, but with following plastic uptake dehydration mold forming method technology illustrate at
The outer station L of type, shaping station M and the position blanking station N are corresponding, make wet base product extrusion dehydration mould assembly A and transfer mould C in
Above three station replaces transfer tasks.
The dehydrating process realized by the plant fiber plastic suction forming apparatus, this method is mainly through plastics sucking moulding, conjunction
Mould squeezes dehydration and transfer three big process process periods of discharging back and forth complete the manufacture of plastic uptake mold forming, and specific operation process is:
Plastics sucking moulding: plastics sucking moulding mould assembly B is sunk in the slurries of stock tank 30, and it is in adsorption operation state that negative pressure, which is opened, such as
1. position in Fig. 6 forms wet base 20 in its shaping mould adsorption, is lifted up after reaching adsorption entails；
Molding squeeze dehydration: plastics sucking moulding mould assembly B is lifted up, finally with the wet base product extrusion dehydration of shaping station M
Mould assembly A molding is molded such as the 2. position in Fig. 6 as shown in Figure 1, the vacuum valve 16 of wet base extrusion dehydration mould assembly A is closed, sent
Air valve 15 is opened, and the compressed gas being filled in gas chamber 3 fills top airtight film 2, the therefore expansion outward of airtight film 2, such as Fig. 2 along air flue 4
It is shown, wet base 20 is sufficiently squeezed, most free waters in wet base 20 are squeezed out, is removed by adsorption forming mould B；Thereafter, change
Become gas control cell operation state, air delivery valve 15 is closed, vacuum valve 16 is opened, and airtight film 2 increases with 3 negative pressure of gas chamber from swelling state
It is fitted in profile in die face 10 from new covering, realization is separated with dewatered wet base 20；
Shift blanking: wet base product extrusion dehydration mould assembly A is separated with plastics sucking moulding mould assembly B, as shown in Figure 6 3.
Position；Thereafter by wet base product extrusion dehydration mould assembly A remove shaping station M, with wet base product extrusion dehydration mould assembly A remove at
Type station M is synchronous, and transfer mould assembly C moves into shaping station M, and molds with plastics sucking moulding mould assembly B, such as the 4. position, 5. in Fig. 6
Position state；At this point, plastics sucking moulding mould assembly B suction stop, shift mould assembly C suction open, force be dehydrated after wet base 20 be transferred to transfer mould
On assembly C, such as the 6. position state in Fig. 6, shifts wet base 20 after mould assembly C carrying is dehydrated, moves to blanking work along horizontal guide rail 12
Position N, mould blanking is spat, at the same time, plastics sucking moulding mould assembly B sinks in the slurries of stock tank 30 again and is transferred to adsorbed state, into
Enter next adsorption mould molding cycle, such as the 7. position in Fig. 6,8. position state.
