Description
The utility model relates to a kind of rotomoulding apparatus, particularly a kind of both arms rotational moulding device.The rotational moulding device is fit to produce large-scale hollow plastic product.State-of-the-art in the world at present rotational moulding device is a kind of four arm rotational moulding machines, as shown in Figure 1.
But this rotational moulding machine die is many, cost is high, complex structure, fault probability are big; And because spiral arm and mould rotation turnover heating furnace, the both sides oven wall need be opened fully, need there be opening positive furnace wall, not only be unfavorable for insulation but also waste energy, the both sides oven wall is opened backward with the Yishanmen form, close forward, make the time of opening wide long owing to stroke is long, waste energy equally and be unfavorable for being incubated; In addition, this machine only is fit to produce in enormous quantities, must assort quadruplet mould ability ordinary production, and the single armed machine that is not suitable as small lot batch manufacture uses.
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of simple in structure, superior performance, cost is low and can quantity-produced rotational moulding device.
The design basis of four arm rotational moulding is slow process for cooling, and goods cool off naturally, and be the twice of fusion time cool time.
The utility model basis is process for cooling fast, and the outside water-cooled of goods is internally air-cooled, only needs 1/10th of fusion time cool time.
Rotational moulding device design of the present utility model comprises a heating furnace, rotary column, a mould, is used to spray the spray equipment of cooling die, the spiral arm that it is characterized in that two molds are arranged, two links to each other respectively with rotary column with a mold and be used to make mould to move back and forth the transmission device that is loaded with described rotary column of turnover heating furnace.Also further comprise the ventilation unit that is used in dies cavity ventilation cooling.
This device method of operation is that a mold plastifies in heating furnace, another set of mould carries out outside spray and inner ventilation cooling simultaneously, and carry out the demoulding and reinforced, with transmission device the mould in heating furnace is withdrawed from then, with rotary column two molds are replaced, with transmission device charged mould is sent into heating furnace and plastify, so move in circles, produce continuously.This device is a chronomere with fusion time, and be about 0.1 chronomere cool time, and the demoulding and reinforced operating time are 0.5 chronomere, and the reinforced operation of the cooling and demoulding two procedures is incorporated in a station and carries out.Article two, spiral arm, two molds, chronomere of every mistake, spiral arm and mould fall once head, realize producing continuously.
This device can be produced continuously with four arm rotational moulding machines are same, but structure simplified widely, has reduced half mould, has reduced cost widely, and product yield and quality do not reduce.This device also can be made single armed machine usefulness, only needs to make a mold, carry out small lot batch manufacture, and because cool time is short, and efficient improves greatly than traditional single armed machine, output is enhanced about more than once.
This device can be suitable for the production of the plastic products of any material (as PE, ABS, AS etc.) and shape.
The heating furnace sidewall need not open wide in the device of the present utility model, the two fan doors that positive furnace wall available reverse opens and closes, and stroke is short, and the time of opening wide is short, has saved the energy and has helped insulation.
The described a kind of ventilation unit that is used to make the dies cavity cooling can comprise air inlet and the exhaust outlet on the mould, the blast pipe that links to each other with described air inlet and wind regime device such as air blast.Blast can be 0.01-0.2kg/cm
2Gas (as air) from the wind regime device during cooling enters die cavity through blast pipe and air inlet, discharges from exhaust outlet then, and heat is taken away.Refrigerating gas also works to support plastic products simultaneously to be made it not separate with die wall.
Described air inlet and exhaust outlet area preferably equate or are close, so that gas turnover speed is identical or close, help cooling and support.
The described another kind of ventilation unit that is used to make the dies cavity cooling can comprise the exhaust outlet on the mould, and a segment distance and sectional area are less than the blast pipe and the wind regime device (as air blast) of exhaust outlet area in exhaust outlet inserts mould.Blast can be 0.01-0.2kg/cm
2Gas (as air) from the wind regime device during cooling enters die cavity through blast pipe, discharges from exhaust outlet then, heat is taken away, and supported plastic products.
The sectional area that the internal perisporium of described blast pipe surrounds preferably with blast pipe and exhaust outlet between the annular space area equate or close.
The transmission device that is used to make mould to move back and forth the turnover heating furnace of the present utility model can comprise the driving that is loaded with described rotary column of a belt wheel and two and described track of taking turns to cooperate (as rail or rail).Driving is advance and retreat in orbit.Driving is advanced, and a mold enters heating furnace plasticizing, and driving a vehicle after plasticizing is finished retreats, withdraw from heating furnace after, Rotate 180 °, driving is advanced, and another set of mould enters the heating furnace plasticizing, the described mould that plastified this moment cools off, the demoulding, reinforced, and circulation is and so forth produced continuously.
Every mold described in the utility model can comprise one or two mould.
Device of the present utility model can comprise X-axis and perpendicular and by the Y-axis of its drive, Y-axis links to each other with mould, and they are used to drive described mould and rotate along spherical track.Like this, help plasticizing and spray cooling.X-axis and Y-axis also can have the inner passage, and blast pipe communicates with the Y-axis inner passage, the X-axis inner passage with one around the groove of Y-axis outer surface with this groove is communicated with the duct that the Y-axis inner passage communicates.
