Abstract
The utility model relates to a ball support molding device for a hail impact test. The device comprises a pressure rod, an outer frame, a top cover, a cylinder and a bottom cover. The middle of the outer frame is hollow, side frames are arranged on the periphery, and the top cover, the cylinder and the bottom cover are arranged on the hollow portion of the outer frame from the top to the bottom. A vertical guide hole is formed in the upper side frame of the outer frame, and the pressure rod penetrates the guide hole vertically. A screw connected with a threaded hole in the upper end of an inner rod is arranged at the lower end of the top cover, and the inner rod is completely disposed in the cylinder. According to the device, the foaming process is not required to be controlled by manual applying of external force, and potential safety hazards are prevented; the quality and the density of the ball support are well controlled; the guide hole is formed in the frame, so that the inner hole perpendicularity is well controlled.
Description
Technical field
The utility model belongs to hail impact test field, relates in particular to a kind of bullet holder device for producing molds for hail impact test.
Background technology
In hail impact test, the quality of bullet holder and quality have a significant impact for the speed tool of controlling hail, if the weight of bullet holder differs, density degree difference, may directly have influence on the speed of hail, causes experimental error; The perpendicularity of bullet holder endoporus, also directly has influence on the flight angle of hail.
There are following two problems in existing technology, and first: in the process of blowing agent foaming, mainly rely on manpower to apply external force, such as directly trampling mould, doing like this, the mould density degree level that not only causes different people to work it out is uneven, also has potential safety hazard; Second: adopt manpower to suppress foaming process, be easy to cause internal mold to be offset, cause the perpendicularity of endoporus not all right, directly have influence on the flight path problem of ice bullet.
In view of above-mentioned defect, the utility model creator has obtained this creation finally through long research and practice.
Summary of the invention
The purpose of this utility model is to provide a kind of bullet holder device for producing molds for hail impact test, in order to overcome above-mentioned technological deficiency.
For achieving the above object, the utility model provides a kind of bullet holder device for producing molds for hail impact test, described bullet holder device for producing molds comprises the bar of exerting pressure, housing, top cover, cylinder and bottom, wherein, in the middle of described housing, be hollow, surrounding arranges frame, and described top cover, cylinder and bottom are arranged on the hollow space of described housing from top to bottom;
On the upper side frame of described housing, be provided with a vertical pilot hole, described in exert pressure bar vertically through this pilot hole;
Described top cover lower end is provided with screw rod, and described screw rod is connected with the screwed hole of interior bar upper end; Described interior bar is placed in described cylinder completely.
The described bar top of exerting pressure is one handle, and lower end also arranges a backing plate.
Described bottom is arranged on the lower frame of described housing, supports described cylinder.
Described bottom upper end is provided with boss, and described cylinder is directly socketed on described boss; Described boss external diameter and barrel bore are measure-alike.
Further, described screw rod is threaded or pegs graft with described top cover, or directly one-body molded.
Further, on described interior bar, cylinder inner wall and bottom, scribble lubricating oil.
Compared with prior art, the beneficial effects of the utility model are: the utility model no longer needs people to go to apply external force and suppresses foaming process, has avoided potential safety hazard; Quality and the density degree of bullet holder are well controlled; Pilot hole is set on framework, so that the perpendicularity of endoporus is well controlled.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model bullet holder device for producing molds;
Fig. 2 is the decomposing schematic representation of the utility model bullet holder device for producing molds.
The specific embodiment
Below in conjunction with accompanying drawing, technical characterictic and the advantage with other above-mentioned to the utility model are described in more detail.
Refer to shown in Fig. 1, it is the perspective view of the utility model bullet holder device for producing molds, this bullet holder device for producing molds comprises the bar 1 of exerting pressure, housing 2, top cover 3, cylinder 4 and bottom 5, wherein, in the middle of described housing 2, be hollow, surrounding arranges frame, and described top cover 3, cylinder 4 and bottom 5 are arranged on the hollow space of this housing 2 from top to bottom.
On the upper side frame of described housing 2, be provided with a vertical pilot hole, the described bar 1 of exerting pressure is vertically through this pilot hole, and described in the bar top of exerting pressure be one handle, person easy to use presses down or lifts, lower end at the described bar 1 of exerting pressure also arranges a backing plate, in order to increase the contact area of itself and described top cover 3.
Described bottom 5 is arranged on the lower frame of described housing 2, supports described cylinder 4.Described bottom 5 upper ends are provided with boss, and described cylinder 4 is directly socketed on described boss; This boss size is suitable with cylinder 4 internal diameters, guarantees that cylinder 4 can firmly connect described bottom 5.
Described top cover 3 lower ends are provided with screw rod 31, and this screw rod 31 can be threaded or peg graft with described top cover, or directly one-body molded; Described screw rod 31 is connected with the screwed hole of interior bar 32 upper ends; After installation, described interior bar 32 is placed in described cylinder 4 completely.
In the time of work, described screw rod 31 is connected with top cover 3, coats lubricating oil, so that the demoulding on interior bar 32, cylinder inner wall and bottom 5; By described cylinder 4 and bottom 5 combinations, the blowing agent mixing is poured in described cylinder 4, cover top cover 3, described top cover 3, cylinder 4 are put into described framework 2 together with bottom, the bar 1 of exerting pressure described in screwing.
The utility model no longer needs people to go to apply external force and suppresses foaming process, has avoided potential safety hazard; Quality and the density degree of bullet holder are well controlled; Pilot hole is set on framework, so that the perpendicularity of endoporus is well controlled.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for utility model, and nonrestrictive.Those skilled in the art is understood, and in the spirit and scope that require to limit, can carry out many changes to it in utility model right, revise, and even equivalence, but all will fall in protection domain of the present utility model.
