Description of the drawings
Fig. 1 is the structural schematic diagram of air-flowing type self-expanding molding equipment for blowing forward direction section.
Specific implementation mode
With reference to embodiment, the present invention is further described：
As shown in the embodiment shown in fig, which is molded equipment for blowing, which uses and traditional equipment for blowing
Similar structure, it includes forming module 1, and it is symmetrical two pieces that the forming module 1, which is divided to, inside the forming module 1
It is machined with forming cavity 11, the top of the forming cavity 11 is equipped with bottle base 2 to be formed, opening up, the bottle of the bottle base 2
The top that base 2 is open is equipped with the main purge valve 3 that can be moved up and down, and 3 lower part of main purge valve is opened with 2 top of the bottle base
Mouth sealing assembly, the main purge valve 3 can be blown into high-pressure hot gas into the bottle base 2；Two pieces of the left and right of the forming module 1
It opposite can open, when carrying out blowing bottle work, the forming module 1 opens, and such as Fig. 1 of bottle base 2 is put into forming cavity,
Then the main purge valve 3 is fallen, 2 upper end of the bottle base is held out against into closing.In the apparatus, the side wall of the forming cavity 11
On be machined with molding pore 12, return-air hole 13, the molding pore 12 is connected by molding control block 4 with high-pressure gas circuit, described
Return-air hole 13 is connected by molding control block 4 with air suction module.
The air-flowing type self-expanding is molded equipment for blowing in use, being filled with the height of heat into the bottle base 2 by main purge valve 3
It calms the anger body so that bottle base 2 expands, while high pressure draught is blown into the forming cavity by the molding pore 12, then general
Main purge valve 3 is closed, and is at this moment molded the air-flow that pore 12 is blown out and is blown onto bottle base 2, moulding so as to be carried out to bottle base 2,
And the return-air hole 13 is opened simultaneously with molding pore 12 so that the pressure kept constant in forming cavity 11, while described in guarantee
It is molded the steady air current that pore 12 is blown out, the gas shock that the molding pore 12 is blown out can make when on the bottle of expansion
It obtains bottle to be deformed, be blown by the different current rates of all molding pores 12, so that it may so that bottle forms needs
Shape.It can so that bottle stable molding is then shut off institute by reducing temperature in forming cavity 11 after bottle dimensionally stable
Return-air hole 13 is stated can easily to take out the bottle with molding pore 12.It is right by main air outlet valve 3 when the device works
Bottle base 2 carries out heating expansion, moulding to the bottle progress of expansion by being molded the air-flow that pore 12 is blown out, as long as passing through into this way
Type control block 4 come control it is each molding pore 12 blow out air-flow size, thus can conveniently produce the doleiform of needs, when
When needing different doleiforms, it is only necessary to change the air-flow of the blowout of each molding pore.The same molding is only needed in this way
Module 1 can produce different doleiforms, and manufacturing process is simple and fast, and the doleiform production cost of small lot is lower.
In specific design, as shown in Figure 1, the forming cavity 11 is cylindrical shape, the molding pore 12, return-air hole 13
It is distributed on the hole wall of the forming cavity 11.The design of 11 cylindrical shape cavity of the forming cavity easily facilitates processing cylinder class
Bottle.The air suction module is connected with the high-pressure gas circuit, in this way can will be at from the return-air hole 13 by air suction module
Hot gas extraction is discharged into high-pressure gas circuit in cavity 11, and aspiration pump is designed in the air suction module, can be in forming cavity 11
Pumping, while will be discharged into after gas pressurized in the high-pressure gas circuit, it is supplied for high-pressure gas circuit, can be effectively reduced in this way
The use of high pressure gas can effectively reduce gas and follow in this way simultaneously because gas needs the temperature for having certain in forming cavity 11
The loss of heat in ring.It, can also be cold by being blown into molding pore 12 simultaneously after the device is to the just machine-shaping of bottle base 2
Gas so that doleiform is more cooling to fix, and improves the process velocity of plastic bottle.
In the present embodiment, 12 diameter of molding pore is less than 13 diameter of the return-air hole.Specifically, all described
Total pumping section of return-air hole 13 is significantly larger than the blowing section of all molding pores 12, can make to be molded gas in this way
The air-flow that hole 12 is blown out has the wind speed of bigger, is influenced by the return-air hole 13 smaller, and plasticity effect is more preferable.
In specific design, as shown in Figure 1, the molding pore 12 be divided into from top to bottom in forming cavity 11 two groups with
On, every group of molding pore 12 is along 11 axis annular array of forming cavity.This structure design can make the molding pore 12
It gathers in the forming cavity 11, centrosymmetric bottle-shaped structure easy to process can be by every group of molding in specific connection
Pore 12 accesses in the outlet chamber of the same molding control block 4 so that control is more easy.Similarly in the present embodiment,
The return-air hole 13 is divided into two groups from top to bottom in the forming cavity 11, and every group of return-air hole 13 is along forming cavity 11 axis annular
Arrangement.Two groups of return-air holes 13 are symmetrical above and below so that pumping effect is more preferable.
In the present embodiment, the outside of the forming cavity is enclosed with control chamber 41, is equipped in the cavity wall of the control chamber
The molding control block 4, the molding control block 4 are connected by metal hose with the molding pore 12, return-air hole 13 respectively.
The control chamber 41 for wrapping up the forming cavity 11 has insulation effect, and the condition of high temperature, institute are in when 11 internal work of forming cavity
The design of control chamber 41 is stated, the loss of heat can be not only reduced, while the high temperature in control chamber 41 can be effectively isolated, make
It obtains more safe when device work.
In specific design, as shown in Figure 1, the lower part of the forming cavity 11 is machined with bottom outlet 14, the bottom outlet 14 passes through
Bottom control block 5 is connected with high-pressure gas circuit.High pressure draught can be blown out from the bottom outlet in this way, so as to the lower part to doleiform
It carries out moulding.
As shown in Figure 1, the top of the forming cavity 11 is equipped with fixed block 6, the bottle base is assemblied on fixed block 6, institute
It states fixed block 6 to be fixedly connected with the top of the bottle base 2, the forming module 1 and 6 rotatable assembly of the fixed block.In this way
During the device carries out blowing bottle, the forming module 1 can be rotated and so that the molding on 11 inside of the forming cavity is thin
Hole 12, return-air hole 13 follow rotation so as to form the air-flow of annular on bottle so that the moulding effect of bottle is more preferable.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, all in the spirit and principles in the present invention
Within, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
