Abstract
The utility model provides a rotational forming mold for an oil drum, and aims to overcome the defects of high cost, easiness in rustiness and bad corrosion resistance of the existing oil drum, especially a diesel oil drum which is generally made of iron. The mold comprises a mold body, an upper end cover and a lower end cover, wherein an end cover hole is formed in the upper end cover, a double-end positioning screw rod is arranged in the end cover hole, a No.1 nut is positioned on the inner side of the upper end cover and connected with No.1 threads of the screw rod, and a No.2 nut is positioned on the outer side of the upper end cover and connected with No.2 threads of the screw rod. By adopting the rotational forming mold for the oil drum, the sealing effect of the oil drum is effectively improved.
Description
Technical field
The utility model relates to a kind of mould of oil drum, particularly relates to oil drum rotational-moulding mold.
Background technology
Existing oil drum, particularly diesel bucket, generally adopt metal bucket, metal bucket have cost high, easily get rusty, the shortcoming of corrosion-resistant, therefore, by rotation molding legal system, making oily plastics oil drum becomes a kind of trend.When rotation molding, need to oil drum, carry out rotation molding processing with mould, but not this mould sale in the market.
Utility model content
The purpose of this utility model is for using the deficiency of rotational-moulding mold in prior art without oil drum, a kind of oil drum rotational-moulding mold being provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of oil drum rotational-moulding mold, comprise die body, upper end cover and bottom end cover, on described upper end cover, ending cover hole is set, double end positioning screw is set in described ending cover hole, described nut one is positioned at the inner side of described upper end cover and is connected with described screw flight one, and nut two is provided with the outside of described upper end cover and is connected with screw flight two;
On the circumference of described nut one, be provided with middle boss radially;
The inner side that is positioned at described upper end cover of described double end positioning screw is provided with positioning step;
The end cap wall that is provided with ending cover hole place of described upper end cover sinks to forming thin-walled place, between the excircle of described upper end cover and nut one, is provided with gap;
The inner face place of described nut one arranges the radial convex edge of convex, corresponding with position and the shape on described radial convex edge, on double end positioning screw, is provided with radial groove, and described radial convex is along being positioned at described radial groove;
Described ending cover hole is more than two, and the double end positioning screw that at least one is connected with ending cover hole is provided with axially extending bore.
Adopt the oil drum rotational-moulding mold of the utility model structure, owing to being provided with ending cover hole on upper end cover, double end positioning screw is set in ending cover hole, the two ends of double end positioning screw lay respectively at inner side and the outside of end cap, and by screw flight one attaching nut one who is positioned at inner side, so nut one is fixedly installed in die body, when rotation molding, nut one can be connected with the top cover of oil drum, nut one is fixed on the top cover of oil drum, oil drum is sealed, simultaneously, because inner face and the circumferential surface of nut one all leaks in die body, so can form heavy wall place on oil drum top cover, nut one is securely fixed on oil drum top cover, improve the sealing effectiveness of oil drum.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model will be further described:
As Figure 1-5, rotational-moulding mold for this oil drum, comprises die body 3, upper end cover 1 and bottom end cover 2.On upper end cover, be provided with ending cover hole 4, in ending cover hole 4, be provided with double end positioning screw 5.One end of double end positioning screw 5 is screw flight 1, and the other end is screw flight 2 14.Screw flight 1 is arranged on die body 3 inside, and is connected with nut 1, and screw flight 2 14 is arranged on the outside of die body 3, and is connected with nut 28.
Preferably, in the bar portion of double end positioning screw 5, be provided with positioning step 9, this positioning step 9 is positioned at the inner side of upper end cover 1, is namely positioned at die body 3, and double end positioning screw 5 is positioned at the inner side of upper end cover 1 by this positioning step 9.
Preferred structure is on the excircle of nut 1, to be disposed radially middle boss 10.The position that the inner side of upper end cover 1 is provided with ending cover hole 4 sinks to forming thin portion, the end cap wall at ending cover hole 4 places sinks can between the excircle of upper end cover 1 and nut 1, reserve gap 11, when gap 11 is conducive to rotation molding, rotational moulding material flows to the outer surface of nut one, nut one and the top cover of oil drum are linked into an integrated entity, and make the place, top cover hole of oil drum form thickening part, nut one is embedded on the inwall of oil drum top cover.
Preferably, screw flight 1 and 10 of positioning steps at double end positioning screw are provided with groove 12, the corresponding radial convex of stretching in end face one place of nut one is provided with is along 13, and shape and size and the groove on this radial convex edge match, and radial convex is along being arranged in groove.The radial convex that setting matches along 13 and groove 12 can prevent nut one displacement when the rotation molding, the position of nut in rotational moulding process is fixed.
