Abstract
A negative make-up apparatus of vacuum sucking-moulding machine comprises a box body, a mould, a water cooling mould disc, a supporting aluminum board, a lower mould plate, up/down drive mechanism, and an air blowing and ejecting apparatus; wherein, the mould is fixed on the water cooling disc, which is fixed on the supporting aluminum board; the aluminum disc and the lower mould are fixed on the up/down drive mechanism; the lower mould is arranged under the supporting aluminum board, and the air blowing and ejecting apparatus is connected with the air ejecting hole on the lower mould through an air blowing pipe. The utility model is characteristics in that the box is arranged with a mouth on the top, that four sealing side boards are arranged on the top to match with the lower mould, that the four sealing side boards are arranged on the four sides of the mould, that an air hole with the open/close controller is arranged on the box. The beneficial effects of the utility model compared with the prior art are that the figure of the slice material after being baked, and that releasing from the mould is relatively easy after moulding, with greatly decreased rate of wasted products, increased production efficiency, with simple structure, easy fulfillment and low cost.
Description
Technical field
The utility model relates to a kind of vacuum plastic-absorbing machine, more specifically to a kind of vacuum forming device of vacuum plastic-absorbing machine.
Background technology
Existing vacuum plastic-absorbing machine, the vacuum forming device that is adopted, when baking sheet, the deliquescing because sheet material is heated, its middle part is not supported, so the sheet of falling easily, influences the quality of moulding, the percent defective height, and after the moulding, goods are not easy the demoulding.
Summary of the invention
The purpose of this utility model provides a kind of vacuum forming device of vacuum plastic-absorbing machine, can control the shape of sheet material behind the roasting sheet, and goods demoulding ratio is easier to after the moulding, and the technical scheme of employing is as follows:
The vacuum forming device of vacuum plastic-absorbing machine of the present utility model, comprise casing, mould, the water-cooled mould, lower bolster, lift drive mechanism and take out aerating device, mould is fixed on the water-cooled mould, the water-cooled mould is fixed on the lower bolster, lower bolster is fixed on the lift drive mechanism, taking out aerating device links to each other with aspirating hole on the lower bolster by exhaust tube, it is characterized in that: described casing upper end open, and the upper end is provided with four sealing side plates that cooperate with lower bolster, four the sealing side plate lay respectively at mould around, also be provided with air-vent and air-vent folding control device on the casing.
Like this, when baking sheet, sheet material to be processed and casing form a confined space, and when baking sheet, because the effect of gas in the confined space, sheet material to be processed is not easy tenesmus like this.Therefore and the casing of the vacuum forming device of conventional vacuum Packing Machine is actually a frame, can't form a confined space with sheet material, thus the tenesmus of sheet material middle part, the phenomenon of the sheet that can occur falling.Like this, by air-vent folding control device, can control the shape of sheet material behind roasting sheet.And can control the pressure of gas in the casing by taking out aerating device, increase the pressure of gas in the casing, sheet material is upwards heaved, make the suitable pressure of gas maintenance in the casing, just can make sheet material keep smooth, reduce the pressure of gas in the casing, therefore sheet material can control the shape of sheet material according to actual needs just to tenesmus.
In the time will carrying out thermoforming, lift drive mechanism drive mould, water-cooled mould, lower bolster move upward to the operating position, and four sealing side plates contact with lower bolster, and form a confined space with sheet material to be processed, take out aerating device and bleed.At this moment, because lower bolster can be to sinking, the effect that influence vacuumizes, just need air-vent folding control device control air-vent to open, air pressure and the outer air pressure of casing in the casing are consistent, thereby avoid lower bolster to sinking, other the time air-vent folding control device control air-vent closure, avoid air to come in and go out from air-vent.
Described air-vent folding control device is a cylinder.
Described air-vent folding control device also can be an electrically operated valve.Like this, when thermoforming, electrically operated valve is opened, and casing and case are communicated with outward, and the outer air pressure of air pressure in the casing and casing is consistent, other the time electrically operated valve close.
Described lift drive mechanism is a cylinder.
Described lift drive mechanism is a hydraulic drive mechanism.Also can adopt other similar driving mechanism.
The utility model beneficial effect against existing technologies is, can control the shape of sheet material behind the roasting sheet, and goods demoulding ratio is easier to after the moulding, greatly reduces percent defective, has improved production efficiency, and simple in structure, be easy to realize, cost is low.
Description of drawings
Accompanying drawing is the structural representation of the utility model preferred embodiment.
The specific embodiment
As shown in drawings, the vacuum forming device of the vacuum plastic-absorbing machine in this preferred embodiment, comprise casing 1, mould 2, water-cooled mould 3, lower bolster 8, lift drive mechanism 5 and take out aerating device 11, mould 2 is fixed on the water-cooled mould 3, water-cooled mould 3 is fixed on the lower bolster 8, lower bolster 8 is fixed on the lift drive mechanism 5, takes out aerating device 11 and links to each other with aspirating hole 9 on the lower bolster 8 by exhaust tube 10.
Described casing 1 upper end open, and the upper end is provided with four sealing side plates 4 that cooperate with lower bolster 8, four the sealing side plate 4 lay respectively at mould 2 around, also be provided with air-vent 12 and air-vent folding control device on the casing 1, air-vent 12 links to each other with air-vent folding control device.
Like this, when baking sheet, sheet material to be processed and casing 1 form a confined space, and when baking sheet, because the effect of gas in the confined space, sheet material to be processed is not easy tenesmus like this.Also can be by taking out aerating device 11, the shape of control sheet material behind roasting sheet.Can control the pressure of gas in the casing 1 by taking out aerating device 11, increase the pressure of gas in the casing 1, sheet material is upwards heaved, make the suitable pressure of gas maintenance in the casing 1, just can make sheet material keep smooth, reduce the pressure of gas in the casing 1, therefore sheet material can control the shape of sheet material according to actual needs just to tenesmus.
In the time will carrying out thermoforming, lift drive mechanism 5 drive moulds 2, water-cooled mould 3, lower bolster 8 move upward to the operating position, four sealing side plates 4 contact with lower bolster 8, and form a confined space with sheet material to be processed, take out aerating device 11 and bleed.At this moment, need air pressure and casing 1 outer air pressure in the air-vent folding control device control casing 1 to be consistent.
Described air-vent folding control device is a cylinder 13.When thermoforming, cylinder 13 control air-vents are opened, and air pressure and casing 1 outer air pressure in the casing 1 are consistent.
Described lift drive mechanism 5 is cylinders.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be all equivalents of being done according to claim scope of the present utility model, be the utility model claim scope and cover.
