Abstract

The utility model provides a forming device for sealing bottle which includes a mould, an air feeder and a capper. The mould is formed by involution of a left mould and a right mould which are concavely provided with at least one mould impression oppositely and respectively. The mould impressions after involution forms a forming space for a primary embryo to be arranged in. The air feeder is arranged on the mould and is provided with a feeding needle that can penetrate into the approach top end part of the primary embryo through the side. The capper can seal the hole left by the feeding needle. The forming device can shorten the manufacture time and lead the left materials not easy to drop in a sealing bottle.

Description

The shaped device of air-tight bottle

[technical field]

The utility model relates to a kind of blowing moulding device, particularly relates to a kind of shaped device that can blow out air-tight bottle fast.

[background technology]

As shown in Figure 1, but the hollow container 1 of general squash type, normally adopt the blowing mould mode and make, the hollow germule 2 that just will be the thermoplastic state is inserted between two side forms 301 of a mould 3, again mold closing and vertically penetrate a blow needle 4 to germule 2 top ends by mould 3 tops, then, be fed into air by blow needle 4, with germule 2 blow moldings, die sinking is taken out and finishing again, so, can make opening hollow container 1 up.

Though, above-mentioned manufacture can produce hollow container 1, but, because the top of hollow container 1 is open bottleneck, so when hollow container 1 transportation and before material fills, be easy to foreign matter and entered in the hollow container 1 and produce and pollute, particularly at the filling tomato ketchup, during food such as salad, its pollution can cause food to eat, cause waste, therefore, the dealer is promptly arranged when blow needle has poured into air and withdraws from germule, use enclosed mechanism that the hole that blow needle stretched through is sealed simultaneously, make and embryogenesis one air-tight bottle just when transportation, promptly do not have foreign matter and enter in the air-tight bottle like this, and when the sealing bottle is desired charge material, again bottleneck is cut filling and get final product.

But because blow needle is arranged on the mould top, when mold closing, blow needle is to fall from top to bottom to pass mould and enter in the germule and blow, so, make that the blow needle displacement stroke is oversize and produce deviation easily when wearing, also lose time simultaneously, in addition, because blow needle is positioned at germule top vertical lift, so the clout that is adhered on the blow needle falls in the air-tight bottle in lifting process easily.

[utility model content]

The purpose of this utility model is to provide a kind of manufacturing time that shortens, and clout is difficult for falling into the shaped device of the air-tight bottle in the air-tight bottle.

The shaped device of the utility model air-tight bottle is to insert for a unshaped germule, and to be blow molded into an air-tight bottle, this shaped device comprises a mould, at least one inflatable body and at least one enclosed mechanism.Mould is to be involuted by a left mould and a right mould, and left and right mould each be concaved with at least one die cavity relatively, respectively form a molding space after the die cavity of left and right mould is involutory, insert for germule, and the profile in moulding space is the face shaping of air-tight bottle.Inflatable body is arranged on left and right mould wherein on the mould, and just corresponding each molding space of each inflatable body, and inflatable body has a blow needle, blow needle is when left and right mould mold closing, penetrate germule proximal portion in the molding space forward by side, to pour into air, with the germule blow molding.Enclosed mechanism respectively is provided with two corresponding plungers, two plungers are separately positioned on the left and right mould, and after germule was blow molded into air-tight bottle, plunger just contracted when withdrawing from molding space behind blow needle, close involutory by the opposite two side places of blow needle toward air-tight bottle, and the hole that blow needle stays is sealed.

[specific embodiment]

As Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, first preferred embodiment of the shaped device 5 of the utility model air-tight bottle is to insert for a unshaped germule, to be blow molded into an air-tight bottle 6, shaped device 5 comprises a mould 10, two inflatable bodies 20 and two enclosed mechanisms 30.

Mould 10 is to be involuted by a left mould 11 and a right mould 12, and left and

right mould

11,12 respectively has a mould pedestal 111 (121), a primary module 112 (122), a bottleneck module 113 (123) and a backform piece 114 (124).Backform piece 114 (124), bottleneck module 113 (123) and primary module 112 (122) are from top to bottom locked in regular turn and are struck up partnership, and locking is on a side of mould pedestal 111 (121), and primary module 112 (122) is concaved with two bottle die cavitys 115 (125) and holds material chamber 116 (126) for two times, expect that chamber 116 (126) respectively is arranged on the bottom of bottle die cavity 115 (125) the following appearance, and bottleneck module 113 (123) is concaved with two bottleneck die cavitys 117 (127), bottleneck die cavity 117 (127) engages with bottle die cavity 115 (125) respectively, in addition, backform piece 114 (124) is concaved with and holds material chamber 119 (129) on two capping die cavitys 118 (128) and two, capping die cavity 118 (128) engages with bottleneck die cavity 117 (127) respectively, and expect that chamber 119 (129) respectively is arranged on the top of capping die cavity 118 (128) the last appearance, backform piece 124 capping die cavitys 128 sides of right mould 12 respectively are the projection shape to dual side-edge edge place, backform piece 114 opposite positions of left side mould 11 then respectively are recess, and when a left side, right mould 11, behind the 12 involutory mold closings, bottle die cavity 115,125, bottleneck die cavity 117,127 and capping die cavity 118,128 joints are formed with two profiles and respectively are the molding space of air-tight bottle 6 face shapings, insert moulding usefulness for germule, and on, following appearance material chamber 116,126,119,129 sides are ccontaining for the flash of germule.

The backform piece 124 that inflatable body 20 installs respectively at right mould 12 is projection shape place, and inflatable body 20 proper corresponding molding spaces, and a cylinder pressure 21 and a blow needle 22 arranged respectively, 22 horizontal displacements of cylinder pressure 21 control blow needles make blow needle 22 when left and

right mould

11,12 mold closings, penetrate germule proximal portion in the molding space forward by side, to pour into air, germule is blow molded into air-tight bottle 6, and during die sinking, then makes shrink back state when originally pressing close to capping die cavity 128 of blow needle 22.

Enclosed mechanism 30 respectively has left plunger 31, one left cylinder pressure 32, one a right plunger 33 and a right cylinder pressure 34, left side plunger 31 is arranged on the backform piece 114 of left mould 11 with left cylinder pressure 32, right plunger 33 then is arranged on the backform piece 124 of right mould 12 with right cylinder pressure 34, and left and

right cylinder pressure

32,34 is controlled left and

right plunger

31,33 horizontal displacements respectively, make corresponding left and

right plunger

31,33 just behind blow needle 22, contract when withdrawing from molding space, close involutory by blow needle 22 opposite two side places toward air-tight bottle 6, with the hole sealing that blow needle 22 is stayed.

As shown in Figure 5, after air-tight bottle 6 demouldings were taken out, the flash of its bottom and the flash on top had excised totally.

As shown in the above description, the utility model is that blow needle 22 is arranged in the backform piece 124 of right mould 12, and quite near capping die cavity 128, therefore, shift length when blow needle 22 uses is very short, wear Shi Buxu and calibrate especially, also deviation can not take place, and can shorten manufacturing time, again because blow needle 22 is to be stretched through in the germule by the side level, so,, also be difficult for when displacement, falling in the air-tight bottle 6 even blow needle 22 is stained with clout when penetrating.
