Thin-walled parts is widely used in producing and life.The size of thin-walled parts on maximum direction be greater than 5 times of its minimum wall thickness (MINI W.), for example the various housings of plastic cement injection moulding or die cast metal moulding.This type of thin-walled parts all has an outside opening, the Mould Machining of loosing core capable of using.The part thin-walled parts simultaneously for economical with materials, needs to exist the opening towards inside for the needs of profile and function.For example, be used for the operation handwheel of valve, main body is cylindrical tube, and hand is non-slip in order to operate, and on the excircle of main body, is parallel to a bump axially is set, and for economical with materials, this bump also adopts thin walled structures.Processing mode of the prior art is opening is turned to other directions or on technology, to increase the opening of other directions and carry out shutoff in the later stage through change design, can increase machining complexity like this, and influence the attractive in appearance of function or outward appearance.
The model utility content:
The purpose of the utility model is to provide a kind of structure that the thin-walled parts of inside opening is arranged, the technical problem that the described this structure that the thin-walled parts of inside opening arranged will solve in the existing technology that thin-walled parts towards inside opening is difficult to process, function or outward appearance can not reach purpose of design.
This structure that the thin-walled parts of inside opening is arranged of the utility model; The housing that comprises plastic cement injection moulding or die cast metal moulding; Include first inner chamber that forms after the demoulding in the described housing, described first inner chamber has a die sinking outlet, wherein; Include one second inner chamber in the described housing; Described second inner chamber has an opening, and second inner chamber is positioned at outside the side of described first inner chamber, and the opening of second inner chamber is communicated with this side of first inner chamber; One side of second lumen openings is provided with an inclined-plane; The die sinking of the described inclined-plane and first inner chamber outlet is adjacent, between the direction of inclined-plane and the first inner chamber die sinking outlet angle greater than 0.1rad is arranged, and the direction of described first inner chamber die sinking outlet is to extend and be parallel to the axial of first inner chamber to opening end from the closed end of first inner chamber.
Further, the length of described housing on its maximum direction is greater than 5 times of its minimum wall thickness (MINI W.).
Further; Described first inner chamber is cylindrical body; The lower end surface opening of first inner chamber, to being outside equipped with a bump, described bump is parallel to extending axially of first inner chamber in the housing; Described second inner chamber is positioned at the inboard of described bump, and the lower end of bump is connected with an edge of the first inner chamber lower end surface through described inclined-plane.
Further again, in the radial plane of first inner chamber, described bump is circular arc, and the housing of the both sides of bump and the first inner chamber periphery is the circular arc transition
The course of working of the utility model is: in the process of plastic cement injection moulding or die cast metal moulding; At first utilize mould to form housing through injection moulding or pressure casting method; After the housing cooling; Keep interior mould of second inner chamber and the relative position between the housing, and from first inner chamber, deviate from all the other moulds, utilize an oblique movement mechanism that the mould in second inner chamber is deviate from from housing then.
The utility model and prior art are compared, and its effect is actively with tangible.The utility model is provided with the inclined-plane between the die sinking outlet of the inside opening of thin-walled parts and thin-walled parts; Adopt the substep release method can make thin-walled parts once-through in mould; Simple and convenient processing method; Improved product and shunk uneven phenomenon, product appearance and function can reach purpose of design, and can save material.
