Description

A kind of rotational molding machine of heating chamber variable volume

Technical field

It the utility model is related to rotational molding machine technical field, and in particular to a kind of rotational molding machine of heating chamber variable volume.

Background technology

Rotation molding is to put into powder material in mould, and heating while makes mould ceaselessly be rolled in direction in length and breadth Rotation, makes material be covered with dies cavity and melt with borrowing self gravitation effect and centrifugal force even action, mould subsequently enters Refrigerating work procedure, is cooled down by modes such as forced ventilations, is demoulded again after cooling, and the product of completion takes out, and then carries out again Next round circulates.The characteristics of rotational molding technique, has：1. the selectivity of equipment and mold is more, adaptable, rotational moulding can produce entirely Product is closed, also plastic large-scale, super-large size plastic hollow product；2. product one-pass molding, internal stress free, is unlikely to deform, nothing Seam, rotational moulding product edge strength are good, it is possible to achieve the thickness of product edge thoroughly solves hollow product edge more than 5 millimeters The problem of relatively thin；Mould need not be adjusted, the wall thickness of rotational moulding product can freely adjust (more than 2mm).3. the shape of rotational moulding product Can be extremely complex, and wall thickness can be more than more than 5 millimeters, product strength is high.4. suitable for multi items, small lot plastic products Production, easily convert product color.It is 5. several in production process without waste materials such as runner, cast gates during rotation molding There is no foundry returns, the wall ratio of product is more uniform, therefore can give full play to the efficiency of material, therefore the technique is for the profit of material It is high with rate, be conducive to save material.

Current rotational molding machine, the heating chamber of particularly shuttle type rotational molding machine is cylindrical type, square-column-shaped, eight prismatics mostly Deng again rotational molding machine of the energy-saving effect preferably with ball-type heating chamber occurs in later in the market.And wherein with ball-type heating chamber Rotational molding machine heating space is optimal.But current rotational molding machine industry still suffers from the problem of one very big, is exactly that rotational molding machine is using During utilization rate be not very high, form the very big wasting of resources.Many users are producing large-scale work using rotational molding machine Energy normal use during part, but when needing to produce miniature workpiece, mould also diminishes, and heating chamber is constant, is so being heated Time and spatially there is very big waste, resource also has very big waste., can only be small by opening if user will save the energy more Mould buys small-sized rotomoulding apparatus to solve.Cost of investment is so not only increased, also is difficult to completely bear in actual use Lotus uses equipment, causes different degrees of idle of equipment, also result in the waste of fund, while also result in the wave of the energy Take, add production cost, and the energy consumed more also form more environmental pollutions.Existing rotational molding machine on Vehicles Collected from Market There is not the equipment that heating chamber space volume can change also.

The content of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of rotational moulding of heating chamber variable volume Machine, is adopted the technical scheme that：

A kind of rotational molding machine of heating chamber variable volume, including work arm rail plate, preceding station work arm, rear station work arm, Before the preceding station work arm is arranged in station trailer driving device, the rear station work arm is arranged on rear station trailer driving dress Put, the preceding station trailer driving device and the rear station trailer driving device are separately positioned on the work arm rail plate Front and back can simultaneously be moved forward and backward relative to the work arm rail plate, it is characterised in that：Further include and slided with the work arm The heating chamber rail plate of dynamic guide rail right-angled intersection, the big left heating chamber trailer driving of left support of the heating chamber rail plate Device and small left heating chamber trailer driving device, big left heating chamber is set in the big left heating chamber trailer driving device, described Small left heating chamber is set in small left heating chamber trailer driving device, and the small left heating chamber can be socketed with the big left heating chamber； The big right heating chamber trailer driving device of right support of the heating chamber rail plate and small right heating chamber trailer driving device, institute State and big right heating chamber is set in big right heating chamber trailer driving device, the small right side is set in the small right heating chamber trailer driving device Heating chamber, the small right heating chamber can be socketed with the big right heating chamber；Heater and circulation are set in the small right heating chamber Wind turbine；The big left heating chamber and big right heating chamber are opposite hemispherical, the two abutting forms big heating chamber；The small left side adds Hot cell and small right heating chamber are also opposite hemispherical, the two abutting forms small heating chamber.

Compared with prior art, the utility model has following features：Heating chamber space can be within the specific limits according to work The big I of part is adjusted change, so that adapt to what rotary space needed for workpiece was minimised as starting point and was invented, advantage It is more to save space than existing rotational moulding machine equipment, more saves the energy, more saves cost, and the reduction of energy consumption, also make ring Border is more environmentally-friendly.
