The utility model absorbs plastic required to be formed to the forming convex mould through vacuum and negative pressure, so that the plastic is formed perfectly, and pictures and texts on plastic cup cover manufactured are clear.
Description
Technical field
The utility model relates to a kind of former of non-toxic plastic bowl cover, having what relate to is the shaped device that adopts the plastics bowl cover of negative pressure of vacuum structure.
Background technology
At present, because plastic cup is easy to use, and purposes more and more widely, as ice river in Henan Province icepro, fruit juice, milk etc. and can come splendid attire with plastic cup or dixie cup, avoid dust to spill in order to make the food in the cup, edible for convenience simultaneously, all a plastics bowl cover to be set on plastic cup or dixie cup.In the prior art, this bowl cover is also finished with a kind of shaped device, this shaped device also is made of cylinder, forming convax mould, molding concave die, also be provided with valve on shaped device, valve is aimed at molding concave die, during moulding, after forming convax mould and the molding concave die coupling, valve ventilation blows to the plastics bowl cover, makes picture and text on the molding concave die can be molded over plastic cup and covers.But the mode of this air-blowing is because pressure is little, often makes picture and text on the molding concave die clearly not to be molded over plastic cup and covers, and makes that the plastics bowl cover after the moulding all becomes substandard products.Adopt this shaped device to produce the plastic cup lid, yield rate is lower.
The utility model content
In view of the deficiency that background technology exists, the technical problems to be solved in the utility model provides a kind of picture and text of mould that make can clearly be molded over the shaped device that plastic cup covers.
For this reason, the utility model is realized by the following technical solutions: a kind of shaped device of plastics bowl cover, include cylinder, forming convax mould, molding concave die, the push rod that it is characterized in that described cylinder is connected with pressing plate, below described pressing plate, be provided with forming convax mould, this forming convax mould is connected with described pressing plate, and the upper surface of forming convax mould and described pressing plate constitute negative pressure cavity, described negative pressure cavity is communicated with vavuum pump by vacuum tube, described forming convax mould is provided with inhales the hole, this suction hole is communicated with described negative pressure cavity, is provided with molding concave die below described forming convax mould, described forming convax mould and described molding concave die coupling; Be provided with the cooling fluid cavity volume in the described pressing plate, this cooling fluid cavity volume is connected with the turnover coolant pipe; Described pressing plate is provided with guide pillar, and described cylinder is provided with the cylinder seat board, and described cylinder block sleeve-board is on guide pillar; Described molding concave die is connected with an elevating mechanism; Described elevating mechanism comprises connecting rod, roller and cam, and an end of described connecting rod is connected with described molding concave die by lifter plate, and the other end is equipped with described roller, and described roller contacts with cam, and described cam and transmission mechanism are in transmission connection.
In the utility model, the upper surface of its forming convax mould and described pressing plate constitute negative pressure cavity, negative pressure cavity is communicated with vavuum pump by vacuum tube, described forming convax mould is provided with inhales the hole, and this inhales hole and the structure that described negative pressure cavity is communicated with, and makes moulding bowl cover suck-back on forming convax mould, because the negative pressure of its generation is big, plastic cup lid is effectively inhaled on forming convax mould, made picture and text on the forming convax mould clearly to be molded over plastic cup and cover, solved the deficiency in the background technology.The cooling fluid cavity volume that is provided with on the pressing plate can make pressing plate cool off at any time, prevents that the bowl cover of moulding is out of shape owing to pressing plate is heated; The cylinder block sleeve-board makes cylinder push-rod reliable and stable in pushing course after on the guide pillar; Molding concave die is with after elevating mechanism is connected, and makes that molding concave die also can lifting, and when the moulding punch moved down, molding concave die rose, and cooperates.
Description of drawings
Further describe relevant details of the present utility model below more in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is not provided with the structure chart of cooling fluid cavity volume on the utility model pressing plate.
The specific embodiment
With reference to accompanying drawing, the shaped device of this plastics bowl cover, include cylinder 1, forming convax mould 8, molding concave die 9, the push rod 19 of described cylinder 1 is connected with pressing plate 6, described forming convax mould 8 is set below described pressing plate 6, this forming convax mould 8 is connected with described pressing plate 6, and the upper surface of forming convax mould 8 and described pressing plate 6 constitute negative pressure cavity 14, for guaranteeing the pressure of negative pressure cavity 14, described forming convax mould 8 is provided with sealing ring 7 with the joint face of described pressing plate 6, described negative pressure cavity 14 is communicated with vavuum pump (not drawing among the figure) by vacuum tube 3, described forming convax mould 8 is provided with inhales hole 15, this suction hole 15 is communicated with described negative pressure cavity 14, and described molding concave die 9 is set below described forming convax mould 8, described forming convax mould 8 and described molding concave die 9 couplings; Be provided with cooling fluid cavity volume 17 in the described pressing plate 6, this cooling fluid cavity volume 17 is connected with turnover coolant pipe 16,18; Cooling fluid circulates by turnover coolant pipe 16,18, and pressing plate 6 is carried out moment cooling, to keep the chilling temperature of pressing plate 6, prevents the distortion of plastics bowl cover.Described pressing plate 6 is provided with guide pillar 4, and described cylinder 1 is provided with cylinder seat board 2, and described cylinder seat board 2 is enclosed within on the guide pillar 4, when regulating the position of cylinder 1, make cylinder seat board 2 to move, guarantee the levelness of cylinder, can produce normal pressure to pressing plate 6 when its push rod 19 is promoted along guide pillar 4; Described molding concave die 9 is connected with an elevating mechanism; Described elevating mechanism comprises connecting rod 10, roller 11 and cam 12, one end of described connecting rod 10 is connected with described molding concave die 9 by lifter plate 13, the other end is equipped with described roller 11, and described roller 11 contacts with cam 12, and described cam 12 is in transmission connection with transmission mechanism.Cam 12 is by the transmission of transmission mechanism, and make lifter plate 13 rise or descend, and then make molding concave die 9 rise or descend, its rising or decline all cooperate described forming convax mould 8, be that moulding die 9 rises, forming convax mould 8 descends, and molding concave die 9 descends, and forming convax mould 8 rises.When the utility model is worked, plastic sheeting after the heating is delivered between forming convax mould 8 and the molding concave die 9, at this moment, the push rod 19 of cylinder 1 promotes pressing plate 6 and forming convax mould 8 moves down, simultaneously, elevating mechanism promotes molding concave die 8 and rises, after both cooperate, carry out one-step forming just, then, vavuum pump work produces negative pressure by vacuum tube 3 in negative pressure cavity 14, thereby by inhaling hole 15 bowl cover of first one-step forming is drawn onto on the forming convax mould 8, makes picture and text on the forming convax mould 8 to be molded over plastic cup clearly and cover.The push rod 19 of cylinder shrinks then, and elevating mechanism makes molding concave die 9 descend simultaneously, and vavuum pump quits work, and carries out the process of demoulding, has just finished forming process.
